 Hello, I am Dr. Bhushan Bari working as a consultant interventional cardiologist in Manipal Hospital, Kharadi, Pune. Today we are going to discuss about effects of smoking on your heart health. Smoking is one of the major factors for coronary artery diseases and it leads to one in four days due to heart attacks. It also is responsible for multiple more critical blockages, early onset heart attacks and poor recovery after the heart attacks. So how does smoking exactly affect your heart? It increases the catacolysm in the level of the senile body which leads to increase in your blood pressure and increase in your heart rate. It also raises the levels of triglycerides. Triglyceride is one of the fat in your blood. It also reduces the HDL that is high density lipoprotein. High density lipoprotein is a good cholesterol so smoking reduces the level of HDL. It also leads to formation of atherosclerotic plugs comprising of cholesterol, fat and calcium in the blood vessels. Smoking also makes the blood more sticky when more prone for clotting which can block the arteries. Also it leads to something called as endothelial dysfunction. So endothelial lining is the inner cell lining of the blood vessel. So because of endothelial dysfunction there are chances of formation of atherosclerotic plugs. So in general it leads to narrowing of the blood vessels supplying the critical organs in the body. So please quit smoking and make everyone around you to do so because smoking in any form is dangerous be it active or passive. Thank you.
