Acute Coronary Syndrome (ACS) is an umbrella term for a group of clinical symptoms that can occur when the blood supplied to the heart muscle is suddenly blocked. ACS is the most common cause of morbidity and mortality in the US, with approximately 1.5 million hospital discharges in the US involving patients with ACS, and accounts for half of all deaths due to cardiovascular disease. The economic impact of ACS is also very high, costing Americans more than $150 billion annually.
