Most healthcare providers agree that the first step in fighting heart problems is to quit smoking. The nicotine in cigarette smoke acts as a stimulant, making the heart beat faster and raising the blood pressure. At the same time, nicotine causes the arteries to shrink up, which interferes with the flow of blood in the body and makes the heart work even harder.
Smoking also releases carbon monoxide into the body which lowers the amount of oxygen in the blood.
As a result, the heart has to work harder to supply the oxygen the body needs. Under these conditions, normal activities can make a person breathless and strenuous activity may become impossible. Smoking also makes the blood thick and sticky, so it's easier for clots to form in the arteries, leading to heart attacks or other life-threatening situations. Smoking can also severely damage blood vessels by causing fatty deposits to build up in the walls of the arteries. Clogged arteries make it difficult for the heart to get the oxygen it needs, putting a severe strain on the heart.
