Solution
The rise in blood pressure is due both to an increase in cardiac output and total peripheral vascular resistance.
Nicotine is the main active agent in cigarette smoke, other chemicals and compounds such as tar and carbon monoxide are also harmful to heart in many ways. These chemicals lead to the buildup of fatty plaque in the arteries (atherosclerosis), possibly by injuring the vessel walls. And they also affect cholesterol levels and levels of fibrinogen, which is a blood-clotting material. This increases the risk of a blood clot that can lead to a heart attack or stroke.
