Symptoms and Signs – Differential Diagnosis of Chest Pain
Chest Pain
Thoracic or abdominal organs, such as the heart, pleurae, lungs, esophagus, rib cage, gallbladder, pancreas, or stomach, are often the causative agents of chest discomfort. In addition to being a significant signal of acute and life-threatening cardiac and gastrointestinal problems, chest pain can also arise from musculoskeletal or hematologic disorders, anxiety, and pharmacological treatment.
The onset of chest pain can be either abrupt or gradual, and sometimes its underlying cause may be challenging to determine upfront. The pain may extend peripherally to the arms, neck, mouth, or dorsum. It might manifest as either continuing or sporadic, moderate or sudden. The sensation may vary in kind, ranging from a strong shooting pain to a sense of heaviness, fullness, or even indigestion. It may be triggered or intensified by stress, anxiety, physical activity, conscious breathing, or consuming specific foods.
Emergencies Interventions
Interrogate the patient on the onset of his chest discomfort. Did it manifest abruptly or progressively? Does it exhibit more severity or frequency at present compared to its initial onset? Does any treatment alleviate the pain? Does any factor worsen the pain? Enquire with the patient regarding any related symptoms. Abrupt and intense chest discomfort necessitates immediate assessment and therapy since it could indicate a potentially fatal condition.
Historical Background and Physical Assessment
Should the chest pain be of moderate intensity, continue with the medical history. Question whether the patient experiences widespread pain or can indicate the specific location of the pain. In certain cases, a patient may not interpret the sensation they are experiencing as pain. Therefore, inquire whether they are experiencing any discomfort that extends to their neck, jaw, arms, or back. If he does, invite him to provide a description. Does the sensation like dull, painful, pressure? Has the pain a sharp, stabbing, knifelike quality? Is his sensation palpable externally or internally? Determine if it is a constant or occasional phenomenon. Given its intermittent nature, what is its duration? Request information on whether physical activity, physical effort, respiration, changes in posture, or consumption of specific foods exacerbate or alleviate the pain. Is there any specific factor that appears to trigger it?
Evaluate the patient's medical records for any cardiovascular or pulmonary disorders, chest injuries, gastrointestinal disorders, or sickle cell anemia. Determine his current drug regimen, if any, and inquire about any recent adjustments in dosage or timing.
Take the patient's vital signs, observing for tachypnea, fever, tachycardia, oxygen saturation, pulse that is both paradoxical and either hypertension or hypotension. Additionally, identify any distention of the jugular vein and peripheral edema. Assess the patient's respiratory rhythm and examine his chest for any abnormal expansion. Do a pulmonary auscultation to detect pleural friction rub, crackles, rhonchi, wheezing, or reduced or missing sounds.
Respiratory noises. Scan for murmurs, clicks, gallops, or pericardial friction rubs next. Detect lifts, heaves, thrills, gallops, tactile fremitus, and abdominal masses or soreness by palpation.
Differential Diagnosis of Chest Pain
Angina pectoris
Angina pectoris is characterized by a bodily sensation of constriction or pressure in the chest, which the patient reports as discomfort or a perception of indigestion or enlargement. The discomfort typically manifests in the retrosternal region, encompassing an area of palm size or greater. The radiation may extend to the neck, jaw, and arms, typically to the inner side of the left arm. Angina typically initiates gradually, reaches its peak, and then gradually diminishes. Typically triggered by physical activity, mental strain, or a substantial meal, the discomfort lasts for a duration of 2 to 10 minutes, often not exceeding 20 minutes. Comorbidities include dyspnea, nausea, vomiting, increased heart rate, vertigo, sweating, excessive salivation, and irregular heartbeats. The presence of an atrial gallop, which is a fourth heart sound, or a murmur may be detected during an anginal episode.
Prinzmetal's angina, resulting from vasospasm of coronary arteries, usually manifests as chest pain during periods of rest or upon awakening. Concomitant symptoms may include dyspnea, emesis, vertigo, and arrhythmias. Auditory perception of an atrial gallop may occur during an episode.
Anthrax (inhalation)
The acute infectious disease known as anthrax is attributed to the gram-positive, spore-forming bacterium Bacillus anthracis. While the disease mostly affects wild and domestic grazing animals, such as cattle, sheep, and goats, the spores can persist in the soil for an extended period through many years. The disease can manifest in humans who are exposed to infectious animals, diseased animal tissue, or as a result of biological warfare. Primarily, natural cases manifest in agricultural areas across the globe. Anthrax can manifest as cutaneous, inhalation; or gastrointestinal (GI) infection.
Inhalation anthrax is caused by inhalation of aerosolized spores. First indications and manifestations resemble those of influenza and encompass a high body temperature, shivering, debility, a cough, and angina. Typically, the disease progresses in two phases, followed by a time of recuperation following the first manifestations and symptoms. The second phase progresses suddenly with swift decline characterized by a fever, shortness of breath, shallow breathing, and low blood pressure, often resulting in death within 24 hours. The radiological examination reveals mediastinitis and symmetric mediastinal widening.
Anxiety
Acute anxiety, particularly panic episodes, can cause sporadic, acute, stabbing pain often felt under the left breast. This discomfort is incidental to physical activity and has a brief duration of a few seconds. However, the patient may have a precordial aching or a feeling of weightiness that persists for several hours or even days. The usual indications and manifestations include precordial pain, palpitations, fatigue, headache, sleeplessness, dyspnea, nausea, vomiting, diarrhea, and tremors. Panic episodes can be linked to catastrophic occurrences or agoraphobia, which is the phobia of leaving home or being in public places associating with others.
Aortic aneurysm (dissecting)
The start of chest pain accompanying a dissecting aortic aneurysm often occurs abruptly and is particularly intense. In his chest and neck, the patient reports an agonizing tearing, ripping, stabbing pain that extends to his upper back, belly, and lower back. The individual may also exhibit abdominal tenderness, a detectable abdominal mass, increased heart rate, murmurs, fainting, loss of consciousness, weakness or temporary paralysis of the arms or legs, a systolic bruit, systemic hypotension, uneven brachial pulses, lower blood pressure in the legs compared to the arms, and weak or absent femoral or pedal pulses. His complexion is pallid, chilled, perspiration-prone, and discolored below the waist. Toes exhibit an extended capillary refill period, and examination may detect reduced pulse in either one or both carotid arteries.
Asthma
A life-threatening asthma episode is characterized by the abrupt onset of widespread and painful chest tightness, accompanied by a dry cough and slight wheezing. These symptoms then advance to a productive cough, audible wheezing, and severe difficulty breathing. Relevant respiratory observations include the presence of rhonchi, crackles, extended expirations, intercostal and supraclavicular retractions during inspiration, active activation of auxiliary muscles, flared nostrils, and tachypnea. Furthermore, the patient may manifest symptoms such as anxiety, tachycardia, diaphoresis, flushing, and cyanosis.
Blast lung injury
Blast lung damage is the result of a large explosion generating a gust wave that produces intense chest discomfort, skin tears, contusions, edema, and bleeding of the lungs. Common respiratory symptoms include shortness of breath, coughing up blood, rapid breathing, lack of oxygen, wheezing, breathlessness, redness of the skin, reduced breath sounds, and unstable blood pressure. Acts of terrorism on a global scale have heightened the prevalence of this disorder. Chest radiography, arterial blood gas analysis, computerised tomography scans, and Doppler technologies are frequently used diagnostic instruments. There are currently no clear and conclusive recommendations for the care of individuals with Surgical management of blast lung injury depends on the characteristics of the explosion, the surrounding environment, and the presence of any chemical or biological contaminants.
Rheumatic fever
In its acute manifestation, bronchitis causes a sensation of constriction in the chest or a searing ache below the sternum. Moreover, it induces a cough, first arid but thereafter productive, which exacerbates the chest discomfort. Additional symptoms include a mild temperature, chills, a sore throat, arrhythmia, muscular and back discomfort, rhonchi, crackles, and wheezing. More severe bronchitis results in a fever ranging from 101°F to 102°F (38.3°C to 38.9°C) and potential bronchospasm accompanied by worsened wheeze and increased coughing.
Cholecystitis
Cholecystitis usually causes sudden discomfort in the epigastric or right upper quadrant, potentially characterized by sharpness or severe aching. Persistent or sporadic discomfort may extend to the posterior or right shoulder. Frequently observed symptoms include emesis, oedema, pyrexia, perspiration, and rigor. Examination of the right upper quadrant by palpation may detect an abdominal lump, stiffness, enlargement, or redness. Murphy’s sign, which is the occurrence of inspiratory arrest when the examiner palpates the right upper quadrant as the patient takes a deep breath, may also manifest.
Interstitial lung disease
Advanced interstitial lung disease may manifest as pleuritic chest pain, accompanied by increasing dyspnea, cellophane-type crackles, a nonproductive cough, weariness, weight loss, reduced exercise tolerance, clubbing, and cyanosis.
Lung abscess
Pleuritic chest pain gradually manifests in lung abscess disease, accompanied by a pleural friction rub and a cough that produces large quantities of purulent, malodorous, blood-tinged sputum. Pulmonary examination reveals dullness on the afflicted side, accompanied by reduced breath sounds and crackles. In addition, the patient exhibits diaphoresis, anorexia, weight loss, pyrexia, chills, weariness, tenderness, shortness of breath, and clubbing.
Lung cancer
An intermittent aching sensation felt deep within the chest is a common description of the chest discomfort associated with lung cancer. Metastasis of the tumor to the ribs or vertebrae results in localized, persistent, and gnawing discomfort. Common manifestations include cough (sometimes accompanied by blood), wheezing, difficulty breathing, exhaustion, loss of appetite, weight loss, and a high body temperature.
Mitral valve prolapse
While the majority of people with mitral valve prolapse may not show any symptoms, a few may have acute, stabbing chest discomfort before the onset of coronary blockage. The duration of the discomfort can range from a few seconds to several hours and also sometimes resembles the agony experienced in ischemic heart disease. A distinctive indication of mitral prolapse is the presence of a midsystolic click succeeded by a systolic murmur at the apex. Patients may manifest symptoms such as cardiac awareness, migraine headache, dizziness, weakness, intermittent intense fatigue, difficulty breathing, rapid heart rate, mood fluctuations, and palpitations.
Myocardial infarction (MI)
Angina during a myocardial infarction (MI) can last from 15 minutes to several hours. Commonly a constricted pain below the sternum that does not improve with rest or nitroglycerin, it can extend to the patient's left arm, jaw, neck, or shoulder blades. Additional observations include pallor, edema, shortness of breath, excessive sweating, nausea, vomiting, anxiety, restlessness, a sense of imminent catastrophe, low or high blood pressure, an atrial fibrillation, murmurs, and crackles.
Plague caused by Yersinia pestis
. Plague is a very aggressive bacterial infection and, if left untreated, constitutes one of the most potentially fatal illnesses documented. Although most cases are occasional, there is still a possibility for widespread epidemic transmission. Possible clinical manifestations of plague include bubonic (the predominant), septicemic, and pneumonic disease. Transmission of the bubonic form to a human occurs when Infected by a flea bite. Clinical manifestations include pyrexia, rigor, and enlarged, inflamed, and sensitive lymph nodes in close proximity to the flea bite location. Typically, septicemic plague manifests as a fulminant disease with the bubonic form. The pneumonic variant can be transmitted between individuals by direct contact through the respiratory system or by biological warfare through the dispersion and inhalation of the organism aerosols. Acute onset is often abrupt, accompanied by chills, fever, headache, and myalgia. The pulmonary manifestations consist of a productive cough, chest discomfort, tachypnea, dyspnea, hemoptysis, chronic respiratory distress, and cardiopulmonary insufficiency.
Pleurisy
Pulmonary pain of pleurisy develops suddenly and reaches its peak intensity within a few hours. The pain is acute, often penetrating, typically experienced on one side, and situated in the lower and lateral regions of the chest. Prolonged deep breathing, coughing, or thoracic movement typically worsens it. Acoustic examination of the painful region may detect reduced breath sounds, crackles during inspiration, and a rub of the pleura. Also present may be dyspnea, fast, shallow breathing, cyanosis, fever, and weariness.
Pneumonia
Pulmonary infection causes pleuritic chest pain that worsens with deep inhalation and is accompanied by tremors, chills, and fever. The patient presents with a nonproductive cough that subsequently progresses to work. Additional indications and manifestations encompass crackles, rhonchi, tachycardia, tachypnea, myalgia, weariness, nausea, shortness of breath, stomach discomfort, loss of appetite, cyanosis, reduced breath sounds, and excessive sweating.
Pneumothorax
Spontaneous pneumothorax is a potentially fatal condition characterized by abrupt and intense chest pain that is usually localized to one side and rarely grows worse with movement of the chest. A centrally placed ache that extends to the neck may imitate the symptoms of a myocardial infarction (MI). Following the initiation of the discomfort, dyspnea and cyanosis become increasingly severe. Respiratory sounds are reduced or nonexistent on the afflicted side accompanied by increased resonance or tympany, subcutaneous palpitations, and reduced vocal fremitus. Additional symptoms include asymmetrical chest expansion, auxiliary muscle use, a nonproductive cough, tachypnea, tachycardia, anxiety, and restlessness.
A pulmonary embolism
A pulmonary embolism is an occlusion of a lung artery usually resulting from a thrombus formation in a deep vein, leading to chest discomfort or a feeling of choking. The patient usually initially presents with abrupt shortness of breath accompanied by severe angina-like or pleuritic discomfort that worsens with deep breathing and movement of the chest. Additional observations comprise tachycardia, tachypnea, a cough (either nonproductive or generating blood-tinged sputum), a mild temperature, restlessness, diaphoresis, crackles, and peripleural friction rub.
Manifestations include diffuse wheezing, dullness to percussion, indications of circulatory collapse (a feeble, rapid pulse; hypotension), paradoxical pulse, indications of cerebral ischemia (transient unconsciousness, coma, seizures), indications of hypoxia (restlessness), and, especially in older individuals, hemiplegia and other localized neurological impairments. Other less frequent indications include excessive coughing up of blood, splinting of the chest, and swelling of the legs. A patient presenting with a substantial embolus may exhibit cyanosis and distension of the jugular vein.
Q fever
Q fever is a rickettsial illness resulting from the infection by Coxiella burnetii. Human infection chiefly arises from contact with infected animals. Cattle, sheep, and goats are the most probable carriers of the pathogen. Transmission of the disease to humans occurs by contact with contaminated milk, urine, feces, or other bodily fluids from affected animals. As well, infection can occur from inhaling infected barnyard dust. Clostridium burnetii is very contagious and is regarded as a potential airborne pathogen for implementation in biological warfare. Manifestations encompass pyrexia, rigor, an intense cephalalgia, lethargy, angina, emesis, and gastrointestinal distress. The fever may persist for a maximum of 2 weeks. More severe instances may result in the patient developing hepatitis or pneumonia.
Sickle cell crisis
In sickle cell crises, chest discomfort often has an unusual distribution. Initial symptoms may manifest as an indistinct discomfort, often affecting the dorsal region, hands, or feet. Exacerbation of the pain leads to its generalization or localization to the abdomen or chest, resulting in intense pleuritic pain. Timely assistance is necessary when confronted with chest discomfort and respiratory distress. The patient may in addition exhibit abdominal distension and stiffness, dyspnea, pyrexia, and jaundice.
Thoracic outlet syndrome
Thoracic outlet syndrome, predominantly resulting in paresthesia along the ulnar distribution of the arm, may be mistaken for angina, particularly when it impacts the left arm. Angina-like pain typically manifests in the patient following activities such as raising arms over the head, working with hands above the shoulders, or lifting a weight. The ache subsides when he lowers his arms. Additional indicators include pallid complexion and a significant disparity in blood pressure between the two arms.
Tuberculotic disease (TB)
Pleuritic chest discomfort and tiny crackles manifest in a patient with tuberculosis following coughing. Common manifestations include nocturnal perspiration, loss of appetite, unintentional weight loss, elevated body temperature, general malaise, difficulty breathing, excessive fatigue, a moderate to severe productive cough, intermittent coughing up blood, lack of response to percussion, heightened sensitivity to touch, and the presence of amphoric breath noises.
Tularemia
Tularemia, sometimes referred to as rabbit fever, is a contagious illness caused by the gram-negative, non-spore-forming bacterium Francisella tularensis. Typically, it is a disease prevalent in rural areas, affecting wild animals, water, and damp soil. Transmission of the disease to humans occurs via a bite from an infected insect or tick, direct contact with infected animal corpses, consumption of contaminated water, or inhalation of the germs. It is identified as a potential airborne agent for use in biological warfare. Following inhalation of the organism, signs and symptoms include sudden onset of fever, chills, headache, widespread muscle soreness, nonproductive cough, shortness of breath, chest discomfort with pleuria, and swelling of the chest.
Additional factors
Chinese Restaurant Syndrome (CRS)
Chinese Restaurant syndrome (CRS) is a non-malignant disorder caused by the excessive consumption of monosodium glutamate, a frequently added ingredient in Chinese cuisine. It imitates the symptoms of an acute myocardial infarction (MI). The patient may present with retrosternal heat, ache, or pressure; a sensation of burning throughout the arms, legs, and face; a complaint of facial pressure; a headache; dyspnea; and tachycardia.
Drugs. Abruptly discontinuing a beta-adrenergic blocker can lead to rebound angina in patients with coronary heart disease, particularly if they have been taking high doses for an extended period.
Special Considerations
As needed, prepare the patient for cardiopulmonary studies, such as an electrocardiogram and a lung scan. Collect a serum sample for cardiac enzyme and electrolyte levels. Explain the purpose and procedure of each diagnostic test to the patient to help alleviate his anxiety. Also, explain the purpose of any prescribed drugs, and make sure that the patient understands the dosage, schedule, and possible adverse effects.
Keep in mind that a patient with chest pain may deny his discomfort, so stress the importance of reporting symptoms to allow adjustment of his treatment.
Patient Counseling
Alert the patient or caregiver to signs and symptoms that require medical attention. Explain the diagnostic tests needed. Provide instructions about any prescribed drugs.
Pediatric Pointers
Even a child old enough to talk may have difficulty describing chest pain, so be alert for nonverbal clues, such as restlessness, facial grimaces, or holding of the painful area. Ask the child to point to the painful area and then to where the pain goes (to find out if it’s radiating). Determine the pain’s severity by asking the parents if the pain interferes with the child’s normal activities and behavior. Remember, a child may complain of chest pain in an attempt to get attention or to avoid attending school.
Geriatric Pointers
Because older patients have a higher risk of developing life-threatening conditions (such as an MI, angina, and aortic dissection), you must carefully evaluate chest pain in these patients.

Thoracic outlet syndrome, predominantly resulting in paresthesia along the ulnar distribution of the arm, may be mistaken for angina, particularly when it impacts the left arm. Angina-like pain typically manifests in the patient following activities such as raising arms over the head, working with hands above the shoulders, or lifting a weight. The ache subsides when he lowers his arms. Additional indicators include pallid complexion and a significant disparity in blood pressure between the two arms.
Tuberculotic disease (TB)
Pleuritic chest discomfort and tiny crackles manifest in a patient with tuberculosis following coughing. Common manifestations include nocturnal perspiration, loss of appetite, unintentional weight loss, elevated body temperature, general malaise, difficulty breathing, excessive fatigue, a moderate to severe productive cough, intermittent coughing up blood, lack of response to percussion, heightened sensitivity to touch, and the presence of amphoric breath noises.
Tularemia
Tularemia, sometimes referred to as rabbit fever, is a contagious illness caused by the gram-negative, non-spore-forming bacterium Francisella tularensis. Typically, it is a disease prevalent in rural areas, affecting wild animals, water, and damp soil. Transmission of the disease to humans occurs via a bite from an infected insect or tick, direct contact with infected animal corpses, consumption of contaminated water, or inhalation of the germs. It is identified as a potential airborne agent for use in biological warfare. Following inhalation of the organism, signs and symptoms include sudden onset of fever, chills, headache, widespread muscle soreness, nonproductive cough, shortness of breath, chest discomfort with pleuria, and swelling of the chest.
Additional factors
Chinese Restaurant Syndrome (CRS)
Chinese Restaurant syndrome (CRS) is a non-malignant disorder caused by the excessive consumption of monosodium glutamate, a frequently added ingredient in Chinese cuisine. It imitates the symptoms of an acute myocardial infarction (MI). The patient may present with retrosternal heat, ache, or pressure; a sensation of burning throughout the arms, legs, and face; a complaint of facial pressure; a headache; dyspnea; and tachycardia.
Drugs. Abruptly discontinuing a beta-adrenergic blocker can lead to rebound angina in patients with coronary heart disease, particularly if they have been taking high doses for an extended period.
Special Considerations
As needed, prepare the patient for cardiopulmonary studies, such as an electrocardiogram and a lung scan. Collect a serum sample for cardiac enzyme and electrolyte levels. Explain the purpose and procedure of each diagnostic test to the patient to help alleviate his anxiety. Also, explain the purpose of any prescribed drugs, and make sure that the patient understands the dosage, schedule, and possible adverse effects.
Keep in mind that a patient with chest pain may deny his discomfort, so stress the importance of reporting symptoms to allow adjustment of his treatment.
Patient Counseling
Alert the patient or caregiver to signs and symptoms that require medical attention. Explain the diagnostic tests needed. Provide instructions about any prescribed drugs.
Pediatric Pointers
Even a child old enough to talk may have difficulty describing chest pain, so be alert for nonverbal clues, such as restlessness, facial grimaces, or holding of the painful area. Ask the child to point to the painful area and then to where the pain goes (to find out if it’s radiating). Determine the pain’s severity by asking the parents if the pain interferes with the child’s normal activities and behavior. Remember, a child may complain of chest pain in an attempt to get attention or to avoid attending school.
Geriatric Pointers
Because older patients have a higher risk of developing life-threatening conditions (such as an MI, angina, and aortic dissection), you must carefully evaluate chest pain in these patients.
