Smoking and heart/cardiovascular disease

Smoking causes an accumulation of fatty substances in the arteries, known as atherosclerosis, the main contributor to smoking-related deaths. Smoking is also a significant contributory factor in coronary heart disease risk. People with coronary heart disease are much more likely to have a heart attack.

Tobacco smoke raises the risk of coronary heart disease by itself. When combined with other risk factors, such as hypertension (high blood pressure), obesity, physical inactivity, or diabetes, the risk of serious, chronic illness and death is huge.

Smoking also worsens heart disease risk factors. It raises blood pressure, makes it harder to do exercise, makes the blood clot more easily than it should. People who have undergone bypass surgery and smoke have a higher risk of recurrent coronary heart disease.

According to the American Heart Association:

"Cigarette smoking is the most important risk factor for young men and women. It produces a greater relative risk in persons under age 50 than in those over 50."
A female smoker who is also on the contraceptive pill has a considerably higher risk of developing coronary heart disease and stroke compared to women using oral contraceptives who don't smoke.

If you smoke your levels of HDL, also known as good cholesterol will drop.

If you have a history of heart disease and smoke, your risk of having such a disease yourself is extremely high.

A much higher percentage of regular smokers have strokes compared to other non-smokers of the same age. The cerebrovascular system is damaged when we inhale smoke regularly.

Those who smoke run a higher risk of developing aortic aneurysm and arterial disease.

"It's easy to quit smoking; I've done it hundreds of times." -- Mark Twain

There are many different ways to give up smoking. Some experts advocate using pharmacological products to help wean you off nicotine, others say all you need is a good counselor and support group, or an organized program. To add to the confusion, you may find there is a study that says this way works better than that one, and then when you look again, you find there is another study that says, no, that one works better than this one.

But one thing most experts agree on is that a combination works best. For example, nicotine replacement therapy on its own, or counseling on its own is not as effective as a combination of the two.

In this article you can read about some of the more common elements of successful quit smoking programs. And at the end is a list of Top Tips to Quit Smoking.
