he rst step in the evaluation of a patient with
T
chest pain is to determine whether the pain is a life-threatening condition. Acute coronary syndrome includes myocardial ischemia and myocardial infarc­tion (MI), aortic dissection, pulmonary embolism (PE), or pneumothorax. These are life-threatening causes of chest pain and must be assessed rapidly so emergent treatment can be initiated. A quick diagnosis of acute MI greatly increases the patient’s chances of survival. Aortic dissection is a rare but catastrophic cause of chest pain. Pulmonary embolism is accompanied by the sudden onset of dyspnea.
If acute ischemic heart disease is an unlikely cause, other causes of acute chest pain should be considered, such as pulmonary, gastrointestinal (GI), psychologi­cal, musculoskeletal, or other conditions (such as peri­carditis). A signicant proportion of patients whose presenting symptoms include acute chest pain have esophageal spasm, or gastroesophageal reux disease (GERD); however, harmless conditions can mimic more serious disease. Pericarditis and valvular dis­eases, such as aortic stenosis and mitral valve prolapse, are less emergent causes of cardiac pain.
Pain in any organ or system can be the result of inammation, obstruction/restriction, or distention/ dilation. All pain arising from the GI, musculoskeletal, respiratory, cardiac, and pulmonary systems transmits to the same spinal cord segments—T1 through T5— and makes identication of the specic origin of dis­comfort difcult. Many causes of noncardiac chest pain relate to chest anatomy, specically skin, muscles, ribs, cartilage, pleura, lungs, esophagus, mediastinum, and thoracic vertebrae.
In an infant, sweat on the forehead can indicate congenital heart disease (CHD). A decrease in cardiac output causes a compensatory sympathetic overactiv­ity, resulting in a cold sweat on the forehead.
In children, chest pain is rarely associated with seri­ous organic disease. The most common causes of chest pain in children are costochondritis, trauma, muscle strain to the chest wall, and respiratory conditions

associated with cough. Chest pain from rheumatic heart disease or other cardiac disease is relatively rare in children. However, patients and families often as­sociate chest pain with heart disease and can be anx­ious about the condition because of reports of sudden death in young athletes.
DIAGNOSTIC REASONING: FOCUSED HISTORY
The identication of potentially acute, life-threatening situations must be made immediately. After you have determined that there is no immediate risk of severe oxygen deprivation to vital organs (e.g., MI, aortic dis­section, and PE), proceed with a focused history.
First, is this a life-threatening condition?
Key Questions
l
Can you describe the pain? What does it feel like?
(Dull, sore, stabbing, burning, squeezing?)
l
Does the pain radiate?
l
When did it start?
l
What were you doing when it started?

What other symptoms have you noticed?
Characteristics of Pain
Typical anginal pain is described as substernal heavi­ness, pressure, or a squeezing sensation that is provoked by exertion and relieved with rest or nitroglycerin. The substernal pain or discomfort radiates to the left shoul­der and down the left arm, and can extend to the neck and lower jaw. An abrupt tearing pain, located in the anterior or posterior chest, characterizes aortic dissec­tion. This pain can migrate to the arms, abdomen, back, or legs. Patients with Marfan syndrome are at risk for aortic dissection.
Pneumonia, PE, and pneumothorax present with chest pain. The patient with PE is able to point to the area of pain over the affected lung and usually
81
82
https://t.me/med1917
Chapter 8  •  Chest Pain
describes a gripping, stabbing pain that is moderate to severe in intensity. The pain can radiate to the neck or shoulders. Patients experiencing a pneumothorax most frequently report mild to severe chest pain of sudden onset, located in the lateral thorax, and radiating to the ipsilateral shoulder. The quality of pain is described as sharp or tearing. Chest pain of pneumonia is located over the area of inltration and does not radiate. It frequently has a burning or stabbing quality, and is as­sociated with cough (see Chapter 11).
Remember that chest pain is subjective and that prior experience, personal attitudes, and cultural values form the patient’s perception of pain. Assessment of the intensity of the pain is done using a 0 to 10 analog scale, with 0 being no pain and 10 being the worst pain ever experienced.
Onset of Pain
Determine if the onset of pain was sudden or gradual, and what the patient’s activity was at the time of onset. The typical onset of angina occurs during ex­ercise, exertion, or emotional stress and is relieved by rest or nitroglycerin. Chest pain of MI can occur at any time and is relieved by rest in 2 to 5 minutes. Sudden onset of chest pain and dyspnea is common with PE. In a pneumothorax, the patient usually reports a sudden onset of severe coughing, exertion, or straining that precipitated the chest pain. Chest pain caused by pneumonia occurs gradually over several hours or days. Chest pain in adolescents that occurs after activity can indicate organic cardiac disease.
Most MIs occur in the morning hours, with a peak on Mondays. Patients might also report acute chest pain hours after heavy exertion, such as snow shovel­ing, sexual intercourse, or other physical activity.
In children, ask about recent choking episodes or swallowing a foreign body if the pain increases with attempts to swallow. Pain that usually occurs when lying down after eating is associated with GERD. Trauma to the chest wall from a fall or strenuous activity can cause rib fractures or chest contusions.
activity, as compared to stable angina pain, which lasts 2 to 5 minutes and is relieved with rest.
Associated Symptoms
The person experiencing an acute MI frequently reports nausea, vomiting, diaphoresis, shortness of breath, and syncope. Pulmonary embolus is often associated with shortness of breath, apprehension, hemoptysis, and chest pain that increases with deep breathing. Fever, cough, and thick sputum production usually accompany chest pain caused by pneumonia.
Does the patient have risk factors for coronary artery disease?
Key Questions
l
How old are you?
l
Do you smoke?
l
Do you have high blood pressure, diabetes, or heart
disease?
l
Do you have a history of myocardial infarction?
l
Has anyone in your family had a heart attack, or
stroke before the age of 60?
Risk Factors
According to the report of the U.S. Preventive Services Task Force, clinically signicant coronary artery disease (CAD) is uncommon in men under 40 and premeno­pausal women, but risk increases with advancing age. The presence of risk factors, such as smoking, hyperten­sion, diabetes, high cholesterol level, obesity, and family history of heart disease increase the risk of CAD. The National Cholesterol Education Program identies the following major risk factors for CAD: cigarette smok­ing, hypertension, low high-density lipoprotein (HDL) cholesterol level (less than 40 mg/dL), a family history of premature coronary heart disease, age (men 45 years and older; women 55 years and older), and diabetes. In addition, a fasting lipoprotein panel should be obtained that includes low-density lipoprotein (LDL) (less than 100 mg/dL is optimal), and total cholesterol values (less than 200 mg/dL is desirable).
Duration
The most life-threatening conditions produce an acute onset of chest pain. The more chronic the pain, the less likely it is that a specic cause will be found. Intermit­tent chest pain that occurs frequently probably indi­cates a more serious problem, such as angina, than one episode of brief, mild pain. Unstable angina is a persistent chest pain, lasting about 30 minutes, not related to

Acute or Chronic
After life-threatening causes of acute chest pain are ruled
out, sudden-onset pain can be associated with trauma,
musculoskeletal injury, or inammation. Chronic, gradual-
onset chest pain is rarely an emergent situation. Chest
pain can be the sequel to an upper respiratory tract infec-
tion. Pain from GERD often occurs at night or after a
large meal.
Location and Character of Pain
Pain arising from the thoracic skin and other super-
cial tissues, such as that associated with furuncles,
contusions, and abrasions, is sharply localized.
Irritation of the intercostal nerves can result in a neuritis that produces sudden onset of a stabbing, burn­ing pain and tenderness. The pain is easy to locate at the intercostal spaces and along inamed nerves with three maximal pain points: adjacent to the vertebrae, in the axillary lines, and along the parasternal lines. Pain can be severe when the patient breathes deeply, coughs, or moves suddenly.
Dorsal root irritation associated with herpes zoster can present with intense burning or knifelike pain along the spine to the lateral thoracic wall and the anterior midline. This pain can restrict movement of the trunk and respirations. Generally this pain is continuous and increases in severity.
Nerve root pain is caused by mechanical irritation or edema of the nerve root. This pain can be felt at the point of irritation, but is frequently referred to points along the peripheral course of the nerve. Thoracic spi­nal segment root pain is often referred to the lateral and anterior chest wall, and is seen with spinal diseases and thoracic deformities.
Costal cartilage that loosens from the brous attach­ment most often causes localized, dulling, aching pain, and tenderness over the eighth, ninth, and tenth ribs on either side; however, the pain can be acute, paroxys­mal, or stabbing.
Musculoskeletal pain is produced by irritation of tissues and transmitted through the sensory nerves. The stimulus travels through the nerve to the dorsal gan­glion and up the spinal afferent pathway to the central nervous system.
Bone pain results from irritation of sensory nerve endings in the periosteum, is intense, and well localized. Chronic diseases affecting the bone marrow can cause a poorly localized pain of varying severity. Ribs are
Chapter 8  •  Chest Pain
83
common sites for metastatic malignant deposits, proba­bly because of their rich vascularity. Metastasis to the rib and the periosteum results in pain. Referred pain from a dermatome is described as intense, aching, and boring.
When tumors involve the mediastinum, chronic aching or dull substernal chest pain is produced by pressure of the tumor against the spine or ribs.
Bronchial pain is caused by the involvement of adjacent structures. The trachea and large bronchus are innervated by the vagus nerve (cranial nerve X). The ner bronchi and lung parenchyma are free of pain innervation, therefore extensive disease can occur in the periphery of the lungs without pain until the process extends to the parietal pleura. Pleural pain, or pleuritis, results from the loss of normal lubricating function, and irritation of the serous mem­branes of the pleural surfaces. The pain waxes and wanes with respirations, movement, and cough. Dia­phragmatic pleural pain can be referred to the base of the neck or abdomen. Children often report chest pain from tachyarrhythmia because they are unable to dif­ferentiate between true pain and the discomfort of the arrhythmia. Cardiac causes of chest pain in children are usually associated with congenital anomalies or acquired diseases of the coronary artery, such as Kawasaki disease.
Sleep
Distinguish between awakening with pain and awaken­ing from pain. Awakening because of pain signals a more serious problem of organic origin, such as car­diac ischemia. Psychogenic chest pain in adolescents commonly accompanies sleep disturbances.
What do associated symptoms tell me?
Key Questions

Do you have a cough or a change in your usual
cough?
l
Do you bring up sputum? If so, how much and what
color?
l
Do you have a fever?
l
Are you lightheaded or dizzy?
l
Do you feel like your heart is racing?
Cough and Sputum Production
Chest pain associated with cough and colored sputum production is usually caused by an acute infection, such as pneumonia. Pain results from a pleural effu­sion, or the collection of uid in the pleural space.
84
https://t.me/med1917
Chapter 8  •  Chest Pain
Sputum associated with pneumonia can be dark green, rust color, or red. Frequent lower respiratory tract infections can be caused by congenital heart disease, with large left-to-right shunts, and an increase in pul­monary blood ow. Children and older adults, with persistent cough, can experience chest pain related to the musculoskeletal strain associated with coughing. People with asthma can develop chest pain from straining of the chest wall muscles caused by tachypnea, coughing, or retraction.
Fever
Fever can indicate pneumonia, myocarditis, pericar­ditis, or PE. It is possible that elderly and immuno­suppressed people will not have fever, even with bacterial infections.
Lightheadedness, Dizziness, or Fainting
Arrhythmias caused by hypoxia, trauma, or electrical shock can cause insufcient coronary blood ow and chest pain. Paroxysmal atrial tachycardia (PAT) can cause lightheadedness. Diastole is shortened in PAT, and thus cardiac output is decreased. Most cases of syncope in adults are caused by cardiac problems such as structural heart disease, arrhythmias, and coronary insufciency. Most cases of syncope in children are benign and are the result of breath holding, ortho­static syncope, hyperventilation, or vasovagal syncopal episodes.
Palpitations
Caffeine, stress, and hormonal changes can cause the sensation of a rapid or forceful heartbeat. Mitral valve prolapse can present with a history of palpitations.
Theophylline, levothyroxine and b-adrenergic agents
can cause arrhythmias such as supraventricular tachy­cardia, which can be perceived as palpitations.
Rib fractures, musculoskeletal strains, and contusions can cause signicant chest pain, especially with move­ment. Musculoskeletal disorders are the most common cause of chest pain in children and younger adults.
Decreased exercise tolerance can result from sig-
nicant heart disease such as shunts, arrhythmias, or CAD. In children, congenital coronary anomalies can arise abnormally (as from the pulmonary artery), take an abnormal course, or have stula connections to other structures, resulting in exertional chest pain. Any episode of moderate to severe chest pain during or after exercise should be investigated as cardiac in origin.
History of Chest Trauma
A careful history of preceding activities should be obtained to detect any recent muscle strain. Posttrau­matic pericardial effusion can develop 1 to 3 months after chest trauma. Blunt injury can cause hemothorax, pneumothorax, soft tissue injury, and rib fracture. A ruptured spleen can cause irritation of the phrenic nerve, producing shoulder pain.
Pain With Movement
Pain of cardiac origin, except for pericarditis, is not affected by respiration. Pain on inspiration suggests pleural etiology. A sharp, pleuritic pain, relieved by sitting upright and leaning forward, suggests pericardi­tis. Pain that is aggravated by chest wall movement, especially along the sternal border, is most frequently costochondritis; both adults and children can experi­ence this inammatory condition of the costal carti­lage. Lying at, consuming alcohol, taking aspirin, eating spicy meals, and wearing tight clothing often precipitate the pain of esophagitis. Frequently, patients report that this pain occurs after lying down following eating a meal.
Is the pattern of pain related to activity and position change?
Key Questions
l
Can you describe your recent physical activities?
l
Have you had any injury to the chest?
l
Does chest movement or position make the pain better
or worse?
Recent Activities
Recent strenuous exercise (especially weight lifting) or horseplay can strain the pectoral, trapezius, latissi­mus dorsi, serratus anterior, and shoulder muscles.
Is there a gastrointestinal origin for the patient’s chest pain?
Key Questions
l
Does the pain get better or worse from eating?
l
Do you have blood in your stools?
l
Have you vomited any blood?
Food Association
Differentiating between esophageal and cardiac origin of chest pain can present a challenge because the character and location of the pain can be very similar. Nitroglycerin can relieve both the pain of angina and

the pain of esophagitis. In these instances, an electro­cardiogram is indicated.
Esophagitis, usually as a result of gastroesophageal reux (GERD), is the most frequent GI cause of chest pain. Patients describe this pain as “heartburn,” or a dull, burning sensation in the epigastric and retroster­nal area. The esophagus is more pain sensitive in its proximal portion. Therefore chest pain that is tempo­rally related to eating meals or particular foods should suggest esophagitis.
Sometimes associated symptoms of a sour taste in the mouth and mild nausea are associated with esophagitis. An esophageal tear or spasm causes more acute, severe chest pain, described as a “tearing” or “crushing” sensation. Frequently the patient experi­encing pain of GI origin reports mild to moderate chest pain occurring intermittently over days to months.
Peptic ulcer and cholecystitis can cause chest pain. Hematemesis (blood in the emesis) or hematochezia (blood in the stool) frequently accompanies peptic ul­ceration. Cholecystitis is frequently reported as right anterior chest pain that radiates to the shoulder or upper back.
Acute pancreatitis should be considered if the chest pain is severe and constant and is reported in the epi­gastric area of the abdomen, radiating to the chest, shoulder, and arm. Pancreatitis is often accompanied by hypotension. Physical examination and diagnostic tests are necessary to differentiate it from chest pain of cardiovascular origin.
cervical and thoracic spine and shoulders can produce upper chest pain. This pain is aggravated by range of motion of the affected joints.
Sickle cell disease (SCD) can cause chest pain. In sickle cell anemia, the erythrocytes become rigid and “sickle,” leading to capillary occlusion and sickle cell crisis. The heart increases the stroke volume to com­pensate for the anemia. The heart gradually dilates and heart failure ensues. Chest pain in a patient with SCD can also originate from acute coronary syndrome (ACS). In this condition, chest pain, fever, dyspnea, and cough are caused by infarction of lung tissue or an infectious agent.
Marfan syndrome is a hereditary connective tissue disease. Cardiovascular involvement occurs in more than 50% of people by age 21. Mitral valve involve­ment is common, with auscultatory ndings of mitral regurgitation and mitral valve prolapse. Marfan syn­drome is associated with an increased risk of aortic dissection.
Kawasaki disease often has a long-term complica­tion of CAD, coronary occlusion, or MI.
What does the family history tell me?
Key Questions
l
Has anyone in your family had heart disease, chest
pain, or sudden death from cardiac arrest?
l
Was anyone in your family born with heart
problems?
l
Does anyone in your family have high cholesterol?
Could this pain be from a systemic cause?
Key Questions
l
Do you have any skin problems?
l
Do you have any chronic health problems?
Skin Symptoms
If the patient reports persistent unilateral chest pain of pruritic, burning, or stabbing quality, consider herpes zoster. This pain will follow the distribution of a cervical or thoracic nerve root. A vesicular rash in the area of pain is characteristic; this rash occurs several days after the occurrence of chest pain.
Systemic Conditions
Chest muscle pain can be caused by localized inam­mation of the muscles in collagen diseases, such as polymyositis, bromyalgia, or systemic lupus ery­thematosus. Arthritic inammatory changes of the
Family History
History of congenital heart disease in close relatives increases the chances of its occurrence in a child. When one child has the condition, the risk of siblings having the condition increases by one-third. Essential hypertension and CAD show a strong family pattern. Hypertrophic cardiomyopathy has a positive family history, with autosomal dominant transmission in one­third of patients.
Children who have a homogenous family history of hypercholesterolemia can present with CAD before the age of 20.
What is the emotional state of the patient?

l
In the past 6 months, have you had a spell or an attack
Chapter 8  •  Chest Pain
in which for no apparent reason your heart suddenly began to race, you felt faint, or you could not catch your breath?
Panic Disorder
A response of “yes” to the above key questions can be a highly sensitive screen for a psychogenic component of pain, and is a positive screen for panic disorder. Patients with anxiety or depression often describe feelings of chest heaviness or tightness that can last for days, and dyspnea unrelated to exertion or rest. Patients can also report difculty taking a deep breath.
DIAGNOSTIC REASONING: FOCUSED PHYSICAL EXAMINATION
A focused physical examination of the patient experi­encing chest pain will provide objective data for the assessment. A thorough examination of the cardiovas­cular, pulmonary, upper GI, dermatologic, and upper body musculoskeletal systems is essential. The electro­cardiogram (ECG) greatly improves the accuracy of the diagnosis of acute chest pain and should be obtained early in the assessment if cardiac causes are suspected.
Observe General Appearance
Initial observation of the patient will provide clues to the severity of the problem. Observe for grimacing, diaphoresis, pallor, cyanosis, tachypnea, use of ac­cessory muscles for breathing, splinting of chest wall, and unequal chest wall excursion. People expe­riencing an MI can be diaphoretic, pale, and anxious. Patients manifesting PE appear diaphoretic and anx­ious; respirations are rapid; splinting of the chest is common; and peripheral cyanosis can be present. People with fractured ribs or signicant chest wall contusions splint their chest wall, and take shallow breaths to avoid aggravating pain with respiratory expansion.
Observe the height and weight of a child. Abnormal
ndings for age can indicate chronic disease.
Measure Vital Signs and Note Respiratory Patterns
Vital signs for people experiencing angina can be within normal ranges. Frequently, however, with acute MI, blood pressure is elevated and cardiac arrhyth­mias are present. Hypotension can indicate cardiogenic shock.
The patient with aortic dissection can be hypoten-
sive with unequal peripheral pulses. Pericarditis can be accompanied by fever, rapid and shallow respirations, and hypertension. Myocarditis can present with fever, respiratory distress, and paradoxical pulse.
In heart failure, decreased stroke volume reduces
the systolic blood pressure, and compensatory vaso­constriction maintains a constant diastolic pressure. This can result in a decreased pulse pressure.
Pneumothorax is manifested by tachypnea and un-
equal chest wall excursion. The patient with pneumo­nia can also be tachypneic, with signs of infection that include fever and a productive cough.
In children, chest pain with tachycardia and hypoten-
sion is generally caused by hypovolemia, secondary to a hemothorax, hemopneumothorax, or vascular injury. Pain can also be caused by rhythm disturbance.
The rate, rhythm, and depth of respirations in patients
experiencing costochondritis, GI disease, or herpes zoster are not usually altered.
Hyperventilation can cause chest pain as a result
of hypercapnic alkalosis or coronary artery vasocon­striction. Most hyperventilation is associated with a stressful event or emotional upset; however, aspirin overdose, severe pain, and diabetic ketoacidosis can be organic causes.
Inspect the Skin
Cool, pale, moist skin can accompany an acute MI, PE, or aortic dissection. Observe the skin overlying the area of chest pain for signs of the vesicular rash of herpes zoster. Petechial rash on the face and shoulders can be a sign of protracted coughing as a result of pneumonia, asthma, or upper respiratory tract infec­tion. Bruises can indicate trauma or abuse.
Palpate Trachea and Chest
Tracheal shift can occur with pneumothorax and in children with atelectasis, involving a signicant por­tion of one lung. To assess the trachea for lateral dis­placement, position your index nger rst on the right side of the suprasternal notch, and then the left. If the trachea has shifted to the side, you will feel the wall on one side but only soft tissue on the other. In a pneumo­thorax, the trachea is deviated to the opposite side during exhalation and toward the side of the pneu­mothorax during inspiration. The trachea is displaced toward a lung that is atelectatic, with the displacement exaggerated during inspiration.
Palpate the entire chest wall for tenderness, depres-
sions, or bulges. Fractured ribs and contusions will
Chapter 8  •  Chest Pain
https://t.me/med1917
87
result in tenderness to palpation and possible defor­mity. Palpate each costochondral and chondrosternal junction. Costochondritis will be manifested by pain with palpation over the cartilage between the sternum and the ribs. Palpation and range of joint motion can elicit arthritic pain in the shoulder or cervical spine. Musculoskeletal chest pain is usually reproduced with palpation or by moving the arms and chest through a variety of positions. Subcutaneous emphysema may be palpable at the neck or upper chest wall. Rib pain on palpation in children without a reported history of trauma can indicate child abuse.
To check the chest wall for symmetry, rst test for diaphragmatic expansion of both the anterior and the posterior thorax between the eighth and tenth ribs. As the patient takes a deep breath, the practitioner places each hand over the chest with thumbs inward. Each thumb should move the same distance from the spine or costal margins. Pneumothorax, pneumonia, and frac­tured ribs can alter this nding.
Percuss the Chest
Percussion in the area of pneumothorax will result in a hyperresonant sound of an air-lled cavity. Areas of inltration, as in pneumonia, will produce a dull or at sound.
Auscultate Breath Sounds
Instruct the patient to breathe through the mouth slowly and deeply. Auscultate systematically from the lung apexes to the lower lobes anteriorly, posteriorly, and laterally (Table 8-1).
Auscultation of bronchial or bronchovesicular breath sounds over the peripheral lungs can indicate consolidation. If breath sounds are diminished over all lung elds, suspect chronic obstructive pulmonary disease (COPD). Obese patients can have breath sounds that are difcult to auscultate. Breath sounds will be inaudible in areas of pneumothorax.
Auscultate for Adventitious Sounds
Adventitious lung sounds are superimposed on normal sounds and can be auscultated over any area of the lung eld during inspiration or expiration. Documentation of abnormal lung sounds should include the type of sound heard, location, and changes during both inspiration and expiration phases of respiration.
Crackles or rales are discontinuous popping sounds heard most often during inspiration. Any disease process that increases peripheral airway resistance, obstructs the peripheral airway, or causes a loss of elastic recoil will produce crackles. These indicate the presence of uid, mucus, or pus in the smaller airways. Fine crackles are soft and high pitched. Medium crackles are louder and lower pitched. Crackles might be heard over the site of a PE.
Wheezing is frequently described as a whistling sound, and can be heard during inspiration, expira­tion, or both. The sound is high pitched and musical. Wheezing indicates that there is uid in the large airways, such as in severe heart failure; more often it is associated with bronchospasm, as seen in asthma. Wheezing occurs on exhalation because that is when small airways collapse. During inhalation, the nega­tive pressure in the chest tends to hold open the air­ways. However, during exhalation, positive pressure in the alveoli is conducted from the outside of the small airways and tends to collapse them. The sound is usually polyphonic; this means that multiple, slightly different, high-pitched sounds are heard at the same time. Most of the causes of wheezing affect many small airways at the same time; each one col­lapses at a slightly different time, creating a slightly different tone. The presence of a single-tone wheeze suggests a single area of blockage, such as with a foreign body. A prolonged expiratory phase of respiration is produced by intrathoracic airway obstruction associated with lower respiratory tract involvement.

Rhonchi are continuous, deep-pitched, coarse breath sounds usually heard during expiration. They are gen­erated by turbulent air passing through secretions in large airways. Rhonchi can be present when the patient has pneumonia.
Pleural friction rub is a grating or squeaking sound heard in the lateral lung elds during inspiration and expiration. It indicates that inamed parietal and visceral pleural linings are rubbing together.
If abnormal lung sounds are detected, additional auscultation for bronchophony, egophony, and whis­pered pectoriloquy are indicated (see Chapter 14).
Auscultate Heart Sounds
Auscultate for normal heart sounds in all positions, iden­tifying S1, S2, rate, and rhythm. Identication of myocar­dial ischemia cannot be reliably performed by physical examination alone. An ECG must be obtained to assess electrical conduction and the condition of myocardial function. Abnormal sounds, such as paradoxical S2 during pain, are a sign of coronary ischemia. A transient, para­doxical S2 could indicate a transient left ventricular dys­function, congestive heart failure, or left bundle branch block. A transient S3 (ventricular gallop) or mitral regur­gitation murmur at the apex can occur occasionally with myocardial ischemia or congestive heart failure. An S4 (atrial gallop) typically indicates a stressed heart, which can be the result of hypertension, MI, or CAD causing heart failure. A summation gallop is the result of an S3, S4, and rapid rate; this can also occur with heart failure. Abnormal rhythms and heart rates are often heard during MI. ECGs are necessary to identify the specic rhythm.
Also note any murmurs and their location, grade, and radiation. Incompetent heart valves produce mur­murs and can be the cause of heart failure. In children, a loud murmur, best audible at the upper right sternal border, or upper left sternal border with a thrill, can indicate a congenital heart defect.
Aortic diastolic murmur can be present with a dis­secting aorta. In aortic valve stenosis, a harsh ejection systolic murmur, with radiation to the neck, is heard on auscultation.
Midsystolic click/late systolic murmur (honk) is heard with mitral valve prolapse. The patient must be examined in both the supine and upright positions to elicit the characteristic sounds.
Observe the Spine for Evidence of Scoliosis
People with scoliosis are at increased risk for pulmo­nary problems because of structural variations that can cause compression of intrathoracic contents.
Examine the Abdomen
Auscultate for bowel sounds. Palpate the abdomen for tenderness and masses. Epigastric pain with palpation can occur with pancreatitis, esophagitis, or peptic ulcer disease. Cholelithiasis or cholecystitis can be mani­fested by pain on palpation in the right upper quadrant. Pancreatitis can produce epigastric pain radiating to the back.
Examine the Extremities
Clubbing of the ngers can be an indication of chronic hypoxia resulting from CHD in children or COPD in adults. Peripheral cyanosis indicates hypoxia if accom­panied by central cyanosis. Consider exposure to a cold environment, or anxiety, if peripheral cyanosis is observed. Lower extremity edema is a sign of heart failure or venous stasis. Note the progression of the edema or whether there is pitting edema up the leg.
Absent peripheral pulse(s) can be a sign of athero­sclerotic vessel disease or dissecting aortic aneurysm. Compare the quality of the pulses bilaterally.
LABORATORY AND DIAGNOSTIC STUDIES
Diagnostic tests are indicated when cardiovascular, pulmonary, or GI pathology is the suspected cause of chest pain. Musculoskeletal and neurological causes of pain usually do not require diagnostic tests.
Electrocardiogram
An ECG can add objective data to the diagnostic pro­cess in evaluating chest pain. ECGs are most valuable when there is a previous ECG with which to compare the ndings, or when serial ECGs are obtained. ST seg­ment elevation or depression indicates the presence of injured myocardium. T wave inversion demonstrates the presence of ischemia. The appearance of both strongly supports ischemia but is not diagnostic of CAD. Arterial spasm, pericarditis, and electrolyte im­balance can also cause these variations from normal. Q waves are indicative of myocardial muscle loss but are not diagnostic of CAD.
Evidence of ischemia is not always obvious on an ECG, even when the patient is reporting anginal pain. This is crucial to keep in mind as you are evaluating a patient with chest pain; a normal ECG rules out isch­emia in the setting of ongoing chest pain.
Stress Testing
People experiencing intermittent chest pain who have a normal ECG and are not taking digoxin should have
