What is coronary thrombosis? Explained

Coronary thrombosis is a condition where a blood clot forms in an artery that supplies blood to the heart. This blockage can severely restrict blood flow, potentially leading to a heart attack. The actor Nana Patekar's death after a blood clot blocked his left main coronary artery drew attention to this serious health issue. Coronary thrombosis occurs when a blood clot forms within a coronary artery, which supplies the heart with oxygen and nutrients.

Atherosclerosis, characterized by fatty deposits, cholesterol, and other substances building up in the artery walls, is often associated with coronary thrombosis. When a plaque ruptures or its surface is damaged, platelets gather at the site and a clot may form, potentially blocking blood flow. Symptoms of coronary thrombosis include chest discomfort, pain radiating to the arms, shoulders, back, neck, or jaw, breathlessness, sweating, nausea, dizziness, and unusual fatigue.

Immediate medical attention is required if these symptoms occur, especially in individuals with risk factors such as smoking, high blood pressure, high LDL cholesterol, diabetes, physical inactivity, an unhealthy diet, older age, or a family history of heart disease. Diagnosis involves assessing symptoms, medical history, and using tests like electrocardiograms (ECG), blood tests for cardiac troponin, and coronary angiography to determine the location and severity of the blockage.

Treatment focuses on restoring blood flow and preventing further clot formation, using methods like angioplasty, antiplatelet medicines, anticoagulants, and in some cases, coronary artery bypass surgery. Preventive measures involve managing risk factors and adhering to a prescribed treatment plan.
