How are smoking and heart disease linked?

Smoking damages the lining of blood vessels, increases fatty deposits in the arteries, increases blood clotting, adversely affects blood lipid levels,and promotes coronary artery spasm. Nicotine accelerates the heart rate and raises the blood pressure.

Smoking cigarettes increases the risk of heart disease, which is America's number one killer. Almost 180,000 Americans die each year from cardiovascular disease caused by smoking. Smoking, high blood pressure, high blood cholesterol, and lack of exercise are all risk factors for heart disease, but smoking alone doubles the risk of heart disease. Among those who have previously had a heart attack, smokers are more likely than non-smokers to have another.

How Smoking Affects the Body

Smoking harms nearly every organ in the body, including the heart, blood vessels, lungs, eyes, mouth, reproductive organs, bones, bladder, and digestive organs. This article focuses on how smoking affects the heart and blood vessels.
