| Chest pain is a common clinical symptom. Several life threatening disorders should be excluded upon presentation. The first diagnostic study to be ordered within 10 minutes is the [[electrocardiogram|12 lead electrocardiogram]]. A full medical history may assist in the prompt management of the patient with chest pain. | | ==[[Chest pain overview|Overview]]== |

| ===Electrocardiogram=== | | ==[[Chest pain natural history, complications and prognosis|Natural History, Complications, and Prognosis]]== |
| * [[Electrocardiogram]] is usually required for initial evaluation.
| |
| * [[ST elevation]] should require further urgent evaluation for reperfusion therapy.
| |
| * Salient findings on ECG are:
| |
| ** New ST elevation (>1 mm) or Q waves on ECG (MI)
| |
| ** ST depression >1 mm or ischemic T waves (unstable angina)
| |
|
| |
|
| ===X-rays of the chest and/or abdomen=== | | ==Diagnosis== |
| *A [[chest X-ray]] can be useful in the initial evaluation of the patient to ascertain if there is [[cardiomegaly]], [[pulmonary edema]] and [[aortic dissection]].

| *[[Computed tomography|CT scanning]] may be better but is often not available
| |
| | |
| ===Echocardiography or Ultrasound===
| |
| * [[Echocardiogram]] usually required for patients with suspected [[coronary artery disease]]
| |
| * To rule out [[aortic dissection]], [[transesophageal echocardiogram]] of the chest may be indicated
| |
| | |
| ===MRI and CT===
| |
| * CT angiography, lung scan may be helpful in ruling out [[pulmonary embolism]] These tests are sometimes combined with lower extremity venous ultrasound or D-dimer testing.
| |
| * To rule out [[aortic dissection]], a [[CT]] scan chest with contrast, [[MRI]] or transesophageal echocardiography can be used.
| |
| ===Other Imaging Findings===
| |
| * [[Ventilation/perfusion scan|V/Q scintigraphy]] or CT Pulmonary angiogram (when a [[pulmonary embolism]] is suspected)
| |
| * For patients who are suspected to have [[coronary artery disease]] may require stress testing or [[cardiac catheterization]]
| |
| * Peak flow studies and pulmonary function tests may be indicated for patients requiring further evaluation
| |
| ===Other Diagnostic Studies===
| |
| * Upper gastrointestinal [[endoscopy]] if [[esophagitis]] is suspected

|
| ===General strategies for management of acute chest pain=== | | ==Case Studies== |
| * In finding the cause, '''the history given by the patient is often the most important tool'''. In [[angina pectoris]], for example, blood tests and other analysis are not sensitive enough ''(Chun & McGee 2004)''.
| | [[Chest pain case study one|Case #1]] |
| * The physician's typical approach is to '''rule-out the most dangerous causes of chest pain first''' (e.g., heart attack, blood clot in the lung, aneurysm). By sequential elimination or confirmation from the most serious to the least serious causes, a diagnosis of the origin of the pain is eventually made. Emergency reperfusion therapy either by percutaneous coronary intervention or thrombolytic agents is recommended after diagnosis
| |
| * Often, no definite cause will be found, and the focus in these cases is on '''excluding severe diseases and reassuring the patient'''.
| |
| * If [[acute coronary syndrome]] (e.g.[[unstable angina]]) is suspected, many patients are admitted briefly for observation, sequential [[ECG]]s, and determination of cardiac enzyme levels over time ([[creatine kinase|CK-MB]], [[troponin]] or [[myoglobin]]). On occasion, later out-patient testing may be necessary to follow-up and make better determinations on causes and therapies.
| |
| * Recommendations regarding the minimum length of stay in a monitored bed for a patient who has no further symptoms have decreased in recent years to 12 h or less
| |
|
| |
|
| ===Immediate Management=== | | ==Related Chapters== |
| * Special attention to: '''airway''', '''breathing''', and '''circulation'''. Supplemental O2 should be administered to patients with suspected [[coronary artery disease]] | | *[[NICE guidelines for management of chest pain]] |
| * Once it's ensured that the patient has stable vitals then a detailed history, physical examination and lab tests are required to reach a diagnosis. Special attention to pain's nature and risk factors are required. | | *[[Unstable angina]] |
| * ECG, cardiac marker, blood test and chest Xrays are initial primary tests done.
| | *[[Chronic stable angina]] |
| * Nitroglycerine and proton pump inhibitors are usually the initial treatment given. However, caution should be taken by the physician in diagnosis based on response to theses therapies as relief of pain on antacids doesn't exclude ischemic heart diseases.
| | *[[Myocardial infarction]] |
| * Treat all underlying etiologies as clinically indicated
