How Smoking Affects Your Heart?
Compared to people who have never smoked, smokers have twice the risk of heart attack. But what makes this habit so bad for our tickers?
Harms of smoking prevent our hearts from working properly. It changes the lining of our heart arteries, allowing fat to build up. This buildup further narrows the arteries, which, in turn, restricts the flow of blood and nutrients through the heart. Smoking also causes blood clots to form together, further obstructing blood flow.

But when you breathe in cigarette smoke, the blood distributed to the rest of the body becomes contaminated with chemicals from the smoke. These chemicals can damage your heart and blood vessels, 1 leading to cardiovascular disease (CVD), the leading cause of all deaths in the United States.
These changes in blood chemistry can cause plaque—a waxy substance that contains cholesterol, scar tissue, calcium, fat, and other substances—to build up in your arteries, the large blood vessels that lead to your heart. carries blood to your body. This plaque buildup can lead to a disease called atherosclerosis.
