How Does Smoking Cause Coronary Heart Disease?

Tobacco present in cigarette or cigar contains innumerable toxins. These toxins are the major cause for developing atherosclerosis. Atherosclerosis is a medical term for what we refer to as hardening of arteries. The hardening occurs gradually as fat start accumulating in the arterial walls. This leads to plaque buildup which narrows the internal arterial lumen. As a result of partial blockage, blood flow becomes restricted or less.

All the arteries of the body are affected to lesser or greater extent. The heart vessels are also affected in the same way and they become narrow. The blood which is saturated with oxygen is unable to flow at its normal, giving rise to chest pain especially with increased activity and extra burden on the heart.

When the arterial blockage is complete, it can lead heart attack.

The toxin nicotine present in tobacco is responsible for it. It increases heart beats, raises blood pressure, and constricts the arteries of the heart as well as in other parts of the body.

Carbon monoxide is another harmful chemical present in tobacco that robs of oxygen from the blood.

Smoking increases the level of LDL cholesterol (bad cholesterol), triglyceride and at the same time it reduces HDL level (good cholesterol) in the blood. These factors are important for buildup and deposition of fats in the coronary vessels.
