Acute Coronary Syndrome (ACS) is one of the most critical cardiac emergencies, caused by reduced blood flow to the heart muscle, often from plaque buildup in the coronary arteries. In this lesson, we’ll explore the role of the left coronary artery, the differences between angina and myocardial infarction, and the types of heart attacks that fall under ACS. You’ll also learn how to identify key EKG changes such as ST depression and T-wave inversion in NSTEMI, understand how tissue death occurs in myocardial infarction, and review the importance of cardiac enzymes in making a timely and accurate diagnosis.
