Acute Coronary Syndrome (ACS) is a critical and potentially life-threatening condition that encompasses a range of cardiovascular emergencies, including unstable angina and myocardial infarction (heart attack). ACS arises from the sudden reduction or blockage of blood flow to the heart muscle, often caused by the rupture of a plaque within a coronary artery. This disruption leads to the formation of blood clots, further compromising blood supply. The hallmark symptoms of ACS include chest pain or discomfort, shortness of breath, and sweating, requiring immediate medical attention. Rapid and accurate diagnosis is paramount, as timely intervention can mitigate damage to the heart muscle and improve patient outcomes. Treatment strategies for ACS may involve medications to alleviate symptoms, restore blood flow, and prevent future events, along with lifestyle modifications and cardiac rehabilitation. Ongoing research continues to refine our understanding of ACS, contributing to advancements in both diagnostic techniques and therapeutic interventions, with the ultimate goal of enhancing the prognosis and quality of life for individuals affected by this cardiovascular emergency.
