What is the link between heart disease, stroke and smoking?

Smoking causes coronary heart disease, accounting for one of every six deaths. Cigarette smokers are 2 to 4 times more likely than nonsmokers to develop coronary heart disease, and cigarette smokers are approximately 2 times more likely to have a stroke.

Both cigarette smoking and exposure to secondhand smoke increase the risk for heart disease. Cigarette smoking reduces circulation in coronary arteries by narrowing the blood vessels, decreasing HDL (good) cholesterol, increasing blood pressure, and increasing clotting in the blood.

Smoking is one of the biggest risk factors for a heart attack. It also puts you at risk for lung cancer, increases your chance of a stroke, and leads to coughing and shortness of breath. The good news is that it’s never too late to quit. If you stop smoking, you’ll improve your health and reduce your long-term risks—and you’ll see immediate benefits, some within just a few hours! And the benefits don’t stop there—within several years your stroke and heart disease risk can equal that of a non-smoker’s and your risk of cancer will be dramatically reduced as well.
