Acute Coronary Syndrome Worldwide Statistics Each year: > 4 million patients are admitted with unstable angina and acute MI > 900,000 patients undergo PTCA with or without stent Myocardial Ischemia Spectrum of presentation silent ischemia exertion-induced angina unstable angina acute myocardial infarction Ischemic Heart Disease evaluation Based on the patient’s history / physical exam electrocardiogram Patients are categorized into 3 groups non-cardiac chest pain unstable angina myocardial infarction Acute Coronary Syndrome Ischemic Discomfort Unstable Symptoms No ST-segment elevation ST-segment elevation Unstable Non-Q Q-Wave angina AMI AMI ECG Acute Reperfusion History Physical Exam Acute Coronary Syndrome The spectrum of clinical conditions ranging from: unstable angina non-Q wave MI Q-wave MI characterized by the common pathophysiology of a disrupted atheroslerotic plaque Unstable Angina - Definition angina at rest (> 20 minutes) new-onset (< 2 months) exertional angina (at least CCSC III in severity) recent (< 2 months) acceleration of angina (increase in severity of at least one CCSC class to at least CCSC class III) Agency for Health Care Policy Research - 1994 Canadian Cardiovascular Society Classification Unstable Angina Likelihood of CAD Previous history of CAD presence of risk factors older age ST-T wave ischemic ECG changes Unstable Angina precipitating factors Inappropriate tachycardia anemia, fever, hypoxia, tachyarrhythmias, thyrotoxicosis High afterload aortic valve stenosis, LVH High preload high cardiac output, chamber dilatation Inotropic state sympathomimetic drugs, cocaine intoxication Unstable Angina prognostic indicators Presence of ST-T-wave changes with pain Hemodynamic deterioration pulmonary edema, new mitral regurgitation, 3rd heart sound, hypotension Other predictors left ventricular dysfunction, extensive CAD, age, comorbid conditions (diabetes mellitus, obstructive pulmonary disease, renal failure, malignancy)
