Best Answer

Smokeless tobacco and cigarettes affects the heart by increasing your chances of getting a heart attack. After constant exposure to the substances in tobacco, the arteries in your body start to shrink. This increases your cholesterol level and white cell count, which in turn causes a blockage in the artery. This restricts the blood and oxygen supply flowing to the heart which triggers the heart attack.
