Coronary thrombosis
Why in News?
Coronary thrombosis is in the news because actor Nana Patekar’s post-mortem report, released on 12 October 2026, reportedly cited acute myocardial infarction due to left main coronary artery thrombosis—a blood clot blocking a major artery supplying the heart—as the cause of death.
What is Coronary Thrombosis?
- Definition: It is the formation of a blood clot (thrombus) inside one of the coronary arteries, which are the primary blood vessels supplying oxygen and nutrients to the heart muscle.
- Mechanism: When a clot partially or completely blocks the artery, it severely restricts or cuts off blood flow.
- The Heart Attack Link: If the blood and oxygen supply are cut off for too long, the heart tissue begins to die, leading directly to a myocardial infarction (heart attack).
Causes and Trigger Factors
- Atherosclerosis: The primary underlying cause is the long-term buildup of fatty deposits, cholesterol, and other materials (called plaque) on the artery walls.
- Plaque Rupture: Clots usually form when a piece of this plaque suddenly ruptures or cracks.
- Platelet Aggregation: In response to the rupture, blood cells called platelets rush to the scene to heal the injury, rapidly clotting and accidentally blocking the entire blood vessel.
- Other Triggers: Vessel wall injuries, severe systemic inflammation, or intense acute stress can also cause sudden clotting.
Common Warning Signs & Symptoms
- Chest Discomfort: Sudden pressure, squeezing, tightness, or pain in the center or left side of the chest.
- Radiating Pain: Pain that spreads outward to the neck, jaw, shoulders, back, or down the arms (especially the left arm).
- Respiratory Issues: Unexplained shortness of breath and difficulty breathing.
- Systemic Signs: Heavy cold sweating, dizziness, lightheadedness, nausea, or profound sudden fatigue.
Who is Most at Risk?
- Existing Heart Conditions: Individuals with diagnosed or undetected coronary artery disease (CAD).
- Lifestyle Factors: Chronic smokers, individuals with a sedentary lifestyle, and those consuming high-fat, unhealthy diets.
- Medical Comorbidities: People suffering from high blood pressure (hypertension), elevated LDL cholesterol, obesity, or diabetes.
- Demographics & Genetics: Individuals over the age of 60, or anyone with a prominent family history of early heart disease.
Diagnosis and Treatment
- Diagnostic Tests: Doctors utilize Electrocardiograms (ECG) to check electrical irregularities, blood tests to screen for cardiac troponin (a protein marking heart damage), and a Coronary Angiography (X-ray with contrast dye) to locate the exact site of the clot.
- Immediate Medications: Emergency first-line treatment includes blood thinners and antiplatelet drugs (like aspirin or heparin) to halt clot growth.
- Surgical Interventions:
- Angioplasty: A balloon catheter is inflated inside the artery to flatten the blockage and instantly restore blood flow.
- Stenting: A tiny mesh tube (stent) is permanently placed inside the artery to keep it structurally open.
