The symptoms of chest pain can help to discern whether there is an underlying cause that may be dangerous. Symptoms that should cause alarm are; chest pain radiating to the back ([[aortic dissection]]), left arm or jaw pain, [[nausea]], [[vomiting]], lightheadedness, and anginal pain that is different from baseline ([[myocardial infarction]]). Pain that is reproduced with palpation, greatest in the abdominal region, radiating to lower extremities, brought on by inspiration, or brought on my movement or postural changes, is less characteristic of [[myocardial ischemia]].

Overview

Chest pain is discomfort or pain that you feel anywhere along the front of your body between your neck and upper abdomen.

Historical Perspective

Classification

Pathophysiology

Causes

There are many organ systems, that when affected, can lead to the symptoms of chest pain. The most common organs involved are the heart, lungs, and the digestive system. Psychiatric disorders, can also lead to the perception of chest pain. The most important facet of diagnosis is distinguishing the life-threatening causes of chest pain, to the more benign causes.

Differentiating Chest pain from Other Diseases

There are several life-threatening causes of chest pain which need to be evaluated for first, which include; myocardial infarction, aortic dissection, esophageal rupture, pulmonary embolism, and tension pneumothorax. The other possible causes of chest pain can be evaluated for by carefully assessing the nature of the pain, and obtaining a thorough patient history.

Epidemiology and Demographics

Risk Factors

Screening

Natural History, Complications, and Prognosis

Chest Pain in Pregnancy

Causes of chest pain in pregnancy are similar to those in the general population. Acute life-threatening causes include myocardial infarction, aortic dissection, tension pneumothorax, as well as thromboembolic diseases that are more common in pregnancy, such as pulmonary embolism and amniotic fluid embolism. Occasionally, chest pain in pregnant women is caused by physiological changes in pregnancy, namely chest expansion and breast tenderness.

Diagnosis

Diagnostic Study of Choice

History and Symptoms

The symptoms of chest pain can help to discern whether there is an underlying cause that may be dangerous. Symptoms that should cause alarm are; chest pain radiating to the back (aortic dissection), left arm or jaw pain, nausea, vomiting, lightheadedness, and anginal pain that is different from baseline (myocardial infarction). Pain that is reproduced with palpation, greatest in the abdominal region, radiating to lower extremities, brought on by inspiration, or brought on my movement or postural changes, is less characteristic of myocardial ischemia.

Physical Examination

Physical examination should focus on evaluating for the life-threatening causes of chest pain first. A complete physical exam should be done, which includes a thorough cardiac, lung, and abdominal exam.

Laboratory Findings

Serial troponins and CK-MB should be ordered. Additional laboratory tests include serum electrolytes, a complete blood count, renal function tests, and liver function tests.

Electrocardiogram

The key findings to look for on EKG is ST elevation which is characteristic of myocardial infarction. Diffuse ST elevation may point to the diagnosis of pericarditis. Serial EKG's should be obtain to evaluate for continued or progression of myocardial injury over time.

X-ray

Chest X-ray can be useful in the initial evaluation of the patient to ascertain if there is cardiomegaly, pulmonary edema and aortic dissection. CT scanning may be better for visualizing the etiology of chest pain depending on the patient history and their symptoms.

Echocardiography and Ultrasound

CT scan

CT angiography may be helpful in ruling out a pulmonary embolism. These tests are sometimes combined with lower extremity venous ultrasound or D-dimer testing. To rule out aortic dissection, a chest CT scan with contrast, MRI or transesophageal echocardiography can be used.

MRI

To rule out aortic dissection, a chest CT scan with contrast, MRI or transesophageal echocardiography may be done.

Other Imaging Findings

Other imaging studies that may be used in the evaluation of chest pain include V/Q scintigraphy, CT angiogram, and endoscopy.

Other Diagnostic Studies

Other diagnostic studies used in the evaluation of chest pain include cardiac stress testing, peak flow studies, and pulmonary function testing.

Treatment

Medical Therapy

A correct diagnosis of the underlying cause of the chest pain should be obtained prior to deciding on an appropriate treatment strategy. The most dangerous causes should be evaluated first. If myocardial infarction or ischemia is suspected, the immediate pharmacotherapies often used include morphine, oxygen, nitrate, aspirin, and possibly also beta-blockers, ACE inhibitors, thrombolytic therapy and Glycoprotein IIb/IIIa inhibitors.

Interventions

Surgery

Surgery may be indicated in the setting of an MI (angioplasty) or in an aortic dissection.
