The Link between Smoking and Heart Disease

Smoking is one of the leading causes of preventable death in the world. It is responsible for numerous health problems, including cancer, lung disease, and heart disease.

How Does Smoking Contribute to Heart Disease?

Smoking damages the heart and blood vessels in several ways.

Nicotine constricts blood vessels, reducing blood flow to the heart. This can lead to angina (chest pain), heart attack, and stroke.

Carbon monoxide in cigarettes binds to red blood cells, reducing their ability to carry oxygen. This can lead to shortness of breath, fatigue, and heart failure.

Tar and other chemicals in cigarettes damage the lining of the arteries, making them more likely to develop atherosclerosis (plaque buildup). Plaque buildup can narrow the arteries and restrict blood flow to the heart.

Smoking also increases inflammation throughout the body, which can damage the heart and blood vessels.

Smoking and Heart Attack

Smoking is a major risk factor for heart attack. In fact, smokers are two to four times more likely to have a heart attack than nonsmokers.

Smoking damages the heart and blood vessels in several ways that make them more susceptible to a heart attack. For example, smoking:

Increases blood pressure

Raises cholesterol levels

Causes inflammation

Damages the lining of the arteries

These changes can lead to the formation of plaque, which is a buildup of fat, cholesterol, and other substances that can narrow the arteries and restrict blood flow to the heart. If a plaque ruptures, it can form a blood clot that can block an artery and cause a heart attack.

Smoking and Stroke

Smoking is also a major risk factor for stroke. In fact, smokers are two to four times more likely to have a stroke than nonsmokers.

Smoking damages the blood vessels in several ways that make them more susceptible to a stroke. For example, smoking:

Increases blood pressure

Raises cholesterol levels

Causes inflammation

Damages the lining of the arteries

These changes can lead to the formation of blood clots, which can travel to the brain and block an artery, causing a stroke.

Other Heart Health Risks of Smoking

In addition to heart attack and stroke, smoking can also increase your risk of:

Coronary artery disease (CAD)

Peripheral artery disease (PAD)

Aortic aneurysm

Buerger's disease

The Bottom Line

Smoking is a major risk factor for heart disease. If you smoke, quitting is the best thing you can do for your heart health. Quitting smoking can reduce your risk of heart disease by up to 50%.

Tips for Quitting Smoking

If you're ready to quit smoking, there are many resources available to help you. You can talk to your doctor, join a support group, or use nicotine replacement therapy. There are also many websites and apps that can help you quit smoking.
