Acute Coronary Syndrome Explained

Acute coronary syndrome (ACS) refers to a group of conditions characterized by sudden, reduced blood flow to the heart. These conditions include acute myocardial infarction (heart attack) and unstable angina. In medical terminology, ACS is the more precise term used to describe these urgent cardiac events. A heart attack can be further classified into two types based on electrocardiogram (ECG) findings: ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI).

Understanding the Underlying Causes

These conditions share a common pathological basis: the rupture or erosion of atherosclerotic plaques within the coronary arteries. When these plaques break apart, they can partially or completely block blood flow through a coronary artery. This blockage leads to ischemia (lack of oxygen) and, in the case of a heart attack, eventual necrosis (death) of heart muscle tissue.

Why Immediate Treatment Is Crucial

Acute coronary syndrome is considered a medical emergency requiring prompt intervention. Whether it's a heart attack or unstable angina, timely treatment is essential. Unstable angina, if not properly managed, can progress to a full-blown heart attack. Therefore, the approach to managing these conditions follows similar principles, focusing on rapid diagnosis and immediate therapy to restore blood flow and prevent further damage.

Standard Treatment Protocols

In the absence of contraindications, treatment for ACS typically involves dual therapy with antiplatelet and anticoagulant medications. These drugs work together to prevent further clot formation and reduce the risk of complications. Early intervention significantly improves outcomes and can be lifesaving.
