In this video, Dr. Anil Kumar Naralasetty explains how smoking greatly increases the risk of a heart attack.
🚭 Over 90% of heart attacks in smokers are linked to smoking-related damage.
Reduced oxygen in blood – Smoking lowers the oxygen supply in the blood and increases hemoglobin levels (16–18 g/dL), making the blood thicker. This can lead to thrombosis — blood clots that block heart arteries.
Endothelium damage – The endothelium is the inner lining of blood vessels. Smoking damages this layer, making it easier for clot-forming elements in the blood to stick together, which can block blood flow to the heart.
Increased clotting elements – Smokers have more direct clot-promoting substances in their blood, further increasing the risk of dangerous clots.
Raised heart rate & blood pressure – Smoking increases heart rate and blood pressure 📈, which strains the heart and causes repeated endothelium damage, leading to more clot formation.
