Sudden cardiac death (SCD) remains a public health problem of immense magnitude, afflicting an estimated 300,000 persons per year in the US.1 SCD, defined as death occurring within one hour from symptom-onset, is associated with ischemic heart disease in 80% of cases. Approximately one-third of cases are the result of an acute occlusion of an epicardial coronary artery.2 Some 50% of the mortality…

Heart disease remains the leading cause of death in the US, with ischemic heart disease comprising almost half of these deaths based on the most recent 2013 mortality data.1 While there have been reports of declining rates of acute myocardial infarction (AMI) from various registries and Medicare beneficiary reports, coronary heart disease remained the underlying cause of death in one out of seven…

Previously considered to be separate disease entities, the acute coronary syndromes (ACS) are somewhat arbitrarily divided on the basis of their electrocardiographic manifestations and are now thought to arise from a common disease process. Based on a number of factors, the severity of the ACS and, consequently, their attendant clinical risk may vary. The management of patients with ACS should…

Why Do We Need Risk Stratification Tools?
Sudden death accounts for between 300,000 and 500,000 deaths each year in North America.1 Patients with a history of myocardial infarction (MI) have a four-fold higher risk of sudden death than those without such a history. Most sudden deaths in ambulatory populations result from life-threatening ventricular arrhythmias that lead to a cardiac arrest.2…

Approximately five million people present to the emergency department (ED) each year with chest pain, and billions of dollars are spent on assessment and treatment. Many therapies are time-dependent, so rapid identification of patients with acute coronary syndrome (ACS) - unstable angina (UA) and acute myocardial infarction (MI) - at high risk for adverse outcomes is essential. Missed or…

Both the art and the science of echocardiography have made tremendous strides in the 50 years since their earliest origins. In its modern-day form, echocardiography maintains a legacy of bedside utility while adopting many of the technologic advances ushered in by the digital era. As a result, it boasts a broad and growing spectrum of application including routine use in primary cardiac diagnosis…

Accurate and timely biochemical marker testing for aiding the diagnosis of myocardial infarction (MI) has been important for the appropriate disposition and treatment of patients for the past several decades. Creatine kinase (CK) muscle and brain (CK-MB) mass and myoglobin measurements were the standard up to the mid-1990s, when assays for the cardiac-specific isoforms of troponin I and troponin…
