arteriosclerosis

DEAR MAYO CLINIC: I know that heart disease is the leading killer among men and women, but is it true that men and women have different risk factors for heart disease? ANSWER: You are correct that heart disease is the leading cause of death in men and women in the United States. Many risk factors are the same for both genders. But there are some differences between men and women that can have an impact on an individual’s risk of heart disease. One of most significant heart disease risk factors for both men and women is smoking. Nicotine can narrow your arteries, and carbon monoxide can damage their inner lining. That makes the vessels more likely to become thick and stiff, a condition known as arteriosclerosis. Eventually arteriosclerosis limits blood flow, increasing the risk of a heart attack. Because of this, heart attacks are more common in smokers than in nonsmokers.
