The Connection between Smoking and Heart Attack
The Connection between Smoking and Heart Attack
Smoking is one of the leading causes of preventable death in the world. It is responsible for a multitude of health problems, including heart disease, stroke, cancer, and chronic obstructive pulmonary disease (COPD).
How Smoking Causes Heart Attacks
Smoking damages the heart and blood vessels in a number of ways:
It increases blood pressure. Nicotine, the addictive chemical in cigarettes, causes blood vessels to constrict, which raises blood pressure. High blood pressure is a major risk factor for heart attack.
It increases inflammation. Smoking triggers inflammation throughout the body, including in the heart and blood vessels. Inflammation is a key factor in the development of atherosclerosis, a buildup of plaque in the arteries that can lead to a heart attack.
It damages the lining of the blood vessels. Smoking damages the endothelium, the thin layer of cells that lines the blood vessels. This damage makes it easier for plaque to form and for blood clots to develop.
It increases the risk of blood clots. Smoking makes blood more likely to clot. This is because nicotine increases the levels of fibrinogen, a protein that helps blood to clot.
It lowers levels of good cholesterol. Smoking lowers levels of high-density lipoprotein (HDL) cholesterol, the "good" cholesterol that helps to protect against heart disease.
The Risk of Heart Attack for Smokers
Smokers are at a significantly increased risk of heart attack compared to non-smokers. The risk of heart attack is:
Twice as high for current smokers as for non-smokers
Three times as high for people who smoke more than a pack of cigarettes per day as for people who smoke less than a pack per day
Four times as high for people who have smoked for more than 20 years as for people who have smoked for less than 20 years
The Benefits of Quitting Smoking
Quitting smoking is one of the best things you can do for your heart health. Within just a few weeks of quitting, your blood pressure and cholesterol levels will start to improve. Your risk of heart attack will also start to decline. The sooner you quit, the greater the benefits will be.
If you are a smoker, talk to your doctor about quitting. There are many resources available to help you quit, including counseling, medication, and support groups.
