2. Cardiac enzymes (Myoglobin, Troponin I and CK MB.)

3. Chest X ray (for exclusion of trauma, pulmonary conditions & aortic aneurysm).

The patient should receive:

1. Aspirin 300 mg for chewing (to prevent propagation of the thrombus)

2. Oxygen inhalation session (5-10 Litres / minute)

3. Nitro glycerine 10 mg sublingual tablets (for coronary vasodilatation) >> ask 1st^ about intake of

sildenafil.

4. Morphine 5-10 mg IV (for relieving pain)

If the patient’s condition improved he should be put under observation for 24 hours.

Drugs taken after stabilization of the condition:

5. Heparin SC injection (to prevent new thrombus formation)

6. Glycoprotein IIb & IIIa inhibitors.

7. Beta Blockers to decrease cardiac demands

8. Diltiazim (if beta blockers are contraindicated, e.g. Asthma)

If the patient’s condition didn’t improve or MI was present

9. Primary PCI within 90 minutes (if available)

10. Thrombolytics if PCI is not available (unless absolutely Contraindicated)

Scientific background

Chest pain

INTRODUCTION

Patients with acute no traumatic chest pain are among the most challenging patients cared for by emergency

physicians. They may appear seriously ill or completely well and yet remain at significant risk for sudden death or an

acute myocardial infarction (AMI).

CLINICAL FEATURES

The typical pain of myocardial ischemia has been described as retrosternal or epigastric squeezing, tightening,

crushing, or pressure-like discomfort. The pain may radiate to the left shoulder, jaw, arm, or hand. In many cases,

particularly in the elderly, the predominant complaint is not of pain, but of a poorly described visceral sensation with

associated dyspnea, diaphoresis, nausea, lightheadedness, or profound weakness. The onset of symptoms may be

sudden or gradual, and

Symptoms usually last minutes to hours. In general, symptoms that last less than 2 minutes or are constant over days

are less likely to be ischemic in origin. Symptoms that are new or familiar to the patient but now occur with

increasing frequency, severity, or at rest are called unstable and warrant urgent evaluation even if they are absent at

the time of presentation. Cardiac risk factors should be used only to predict coronary artery disease within a given

population and not in an individual patient. It should also be mentioned that women, diabetics, and patients with

psychiatric disorders may have more subtle signs of ischemia.

PHYSICAL EXAMINATION

Patients with acute myocardial ischemia may appear clinically well or be profoundly hemodynamically unstable. The

degree of hemodynamic instability is dependent on the amount of myocardium at risk, associated dysrhythmias, or

preexisting valvular or myocardial dysfunction.

Worrisome signs may be clinically subtle, particularly the presence of sinus tachycardia, which may be due to pain

and fear or may be an early sign of physiologic compensation for left ventricular failure. Patients with acute ischemia

often have a paucity of significant physical findings. Rales, a third or fourth heart sound, cardiac murmurs, or rub are

clinically relevant and important findings.

The presence of chest wall tenderness has been demonstrated in 5 to 10 percent of patients with AMI, so its

presence should not be used to exclude the possibility of acute myocardial ischemia.

Also, response to a particular treatment such as nitroglycerin should not be taken as evidence of a certain disease.

DIAGNOSIS AND DIFFERENTIAL Electrocardiography

Of all the diagnostic tools clinically used in assessing chest pain, the electrocardiogram (ECG) is the most

reliable when used and interpreted correctly. Patients with acute infarctions may have ECG findings that

range from acute ST-segment elevations to completely normal. This range means that the ECG is useful only

when it has a positive, or diagnostic, finding. New ST-segment elevations, Q waves, bundle branch block,

and T-wave inversions or normalizations are strongly suggestive of ischemia and warrant

aggressive management in the emergency department (ED). The presence of a normal or

unchanged ECG does not rule out the diagnosis of acute myocardial ischemia.

Serum Markers

Serum markers, if positive, are highly specific for AMI. Myoglobin rises predictably in AMI but is

found in all muscle tissue, making it less reliable in the setting of AMI. Creatinine kinase and its

MB isoenzyme constitute the historical gold standard for diagnosing AMI. Cardiac-specific

troponin I is not found in skeletal muscle, so it has a much greater sensitivity and specificity for

AMI. The documentation of normal serum markers in the bloodstream does not exclude the

diagnosis of AMI.

In addition, these enzymes will not become elevated in serious disease conditions such as

unstable angina. The use of these markers can aid the clinician in assessing risk for patients with

chest pain, including disposition within the hospital. It must be remembered that a serial

enzyme evaluation is needed to appropriately risk stratify individual patients.

Echocardiography

Emergency 2-dimensional echocardiography may have value in the evaluation of chest pain

when the ECG is nondiagnostic, eg, in patients with pacemakers, have a bundle branch block, or

have a baseline abnormal ECG. The finding of regional wall motion abnormalities in the acutely

symptomatic patient is strongly suggestive of active ischemia. Wall motion abnormality also

may represent previous myocardial injury. Twodimensional echocardiography also may aid in

the diagnosis of other conditions that may mimic ischemic disease, such as pericarditis, aortic

dissection, or hypertrophic cardiomyopathy.

Provocative Tests

Many tests currently being performed in some EDs will unmask otherwise unrecognized,

clinically significant ischemic disease. Patients with atypical chest pain and a normal stress

thallium or technetium scan have a very low incidence of short- and long-term subsequent

ischemic events.

Thallium or sestamibi testing can be done in the ED to further risk stratify patients in the

hospital and perhaps be used in consideration for patient discharge from the ED.

Differential Diagnosis

The priority must always be to exclude life-threatening conditions, and the ED physicians

should organize their test-ordering strategies to screen for those conditions first. (Table lists

possible causes of nontraumatic chest pain.)

Table Serious Causes of Chest Pain and Their Presentation
Diagnosis Presentation
Pulmonary embolism Sudden onset, pleuritic pain, and dyspnea
Aortic dissection Tearing pain with radiation to back, neurologic symptoms
Pericarditis Positional ache, dyspnea
Pneumothorax Pleuritic pain and dyspnea
Acute coronary syndrome Vague, pressure-like pain, radiation to arm, neck, jaw
Esophageal rupture Constant retrosternal, epigastric pain, history of inciting event
Pneumonia Pleuritic pain, cough, dyspnea, chills

SPECIFIC CAUSES OF CHEST PAIN Angina Pectoris

The pain of chronic stable angina is episodic and lasts 5 to 15 minutes. It is precipitated by exertion and

relieved with rest or sublingual nitroglycerin within 3 minutes. The pain is typically visceral in nature

(aching, pressure, and squeezing), with radiation to the neck, jaw, arm, or hand. In individual patients

the character of each attack varies little with recurrent episodes. Most patients can differentiate their

usual angina from other causes of pain. Physicians evaluating patients with stable angina should screen

carefully for changes in the pattern that would suggest a shift from stable to unstable angina or even

suggest a different diagnosis.

Unstable Angina :

Patients who complain of recent onset of angina, changes in the character of the angina, or angina at

rest are thought to have an unstable pattern of their angina. They are at risk for an AMI or sudden

cardiac death (see Chapter 21 for management).

Variant (Prinzmetal) Angina

This form of angina is thought to be due to spasm of the epicardial vessels in patients with normal coronary
arteries (one third of cases) or in patients with underlying atherosclerotic disease (two thirds of cases). Pain
typically occurs at rest and may be precipitated by the use of tobacco or cocaine. The ECG typically shows ST-
segment elevations during an acute attack.

Acute Myocardial Infarction

Ischemic pain that lasts longer than 15 minutes, is not relieved by nitroglycerin, or is accompanied by
diaphoresis, dyspnea, nausea, or vomiting suggests the diagnosis of AMI. The clinician must understand the
limitations of the screening tools used in the ED and should have a high level of suspicion for AMI in patients

with risk factors and prolonged or persistent symptoms for whom there is no other clear diagnosis. Aortic

Dissection

This diagnosis should be suspected in the patient who complains of sudden onset of severe, tearing pain in the
retrosternal or midscapular area. High-risk patients are also those at risk for AMI, specifically the middle-age
hypertensive male. The patient may be hypertensive or hypotensive in shock. There may be a diastolic murmur of
aortic regurgitation, indicating a proximal dissection, or distal pulse deficits, indicating a distal dissection. The
dissection may occlude coronary ostia, resulting in myocardial infarction, or the carotids, resulting in cerebral
ischemia and stroke. Chest x-ray, computed tomography, trans esophageal echocardiography (TEE), and

angiography can aid in the diagnosis of this condition. Musculoskeletal Causes

Chest pain due to irritation or inflammation of structures in the chest wall is commonly seen in the ED. Possible
causes include costochondritis, intercostal strain due to severe coughing, and pectoralis muscle strain in the setting
of recent physical exertion. Patients will complain of sharp pain that is worsened with movement of the chest wall
(eg, coughing, and some pain that can be elicited by palpation of the chest wall). These findings in patients without
any other symptoms and no history of significant cardiac disease support the diagnosis of musculoskeletal pain.
This pain is generally responsive to no steroidal anti-inflammatory drugs. It is important to emphasize that the
presence of chest wall tenderness does not rule out the possibility of myocardial ischemia.

Gastrointestinal Causes

Esophageal reflux, dyspepsia syndromes, and esophageal motility disorders can produce chest pain that is difficult
to distinguish from ischemic pain. Patients may complain of burning, gnawing pain associated with an acid taste
radiating into the throat. Pain may be exacerbated by meals, worsen when supine, and may be associated with
belching. Clinicians should determine whether the symptoms are due to a GI disorder based on the clinical
presentation and the absence of findings and/or risk factors suggesting an ischemic cause. Diagnostic decisions
should not be made on the basis of a response to a therapeutic trial of antacids, GI cocktails, or nitroglycerin.

EMERGENCY DEPARTMENT CARE AND DISPOSITION

Assume that every patient complaining of chest pain might be having an AMI.

Patients with suspicious histories should have large-bore IV line established, a cardiac monitor,

supplemental O 2 , and ECG obtained as soon as possible. Vital signs and pulse oximetry should be

monitored continuously.

Ask patients about cardiac risk factors, preexisting coronary artery disease, quality of chest pain, time

of onset and duration of symptoms, and whether the pattern has been stable, unstable, continuous, or

intermittent. Ask specifically for clues to noncardiac causes of chest pain: ability to elicit pain by

movement or cough; the relation of pain to meals; or pain that is of sudden onset, referred to the back,

or pleuritic in nature.

Examine patients while noting evidence of heart failure or valvular insufficiency, pericardial rubs, or

tenderness of the chest wall. Specifically, physicians should ask whether pain elicited on palpation of

the chest wall exactly reproduces the patient's pain.

An ECG should be obtained on all patients for whom there is a reasonable suspicion of myocardial

ischemia. A normal ECG, although minimizing the likelihood of an AMI, does not definitively rule out the

possibility of MI.

If the etiology of chest pain remains unclear in some patients, clinicians should consider more diagnostic

tests as guided by clinical suspicion and findings.

Clinicians should not use patients' clinical response to GI cocktails, nitroglycerin, or NSAIDs to exclude

the possibility of myocardial ischemia.

In patients with nondiagnostic ECGs for whom there is a clinical suspicion for ischemia, clinicians should

consider provocative testing, echocardiography, or admission and observation. Physicians should not

rely on serum enzyme testing to rule out the possibility of clinically significant disease.
