Does cigarette smoking have an effect on coronary heart disease?

Cigarette smoking is widely recognized as a significant risk factor for coronary heart disease (CHD). Numerous studies have established a clear causal relationship between smoking and the development of CHD. When individuals smoke, harmful chemicals in tobacco can damage the lining of blood vessels, promote atherosclerosis (the buildup of plaque in arteries), and lead to increased heart rate and blood pressure—all of which contribute to the risk of heart disease.

The assertion that smoking does not have an effect on coronary heart disease is not supported by scientific evidence. In fact, smoking is known to increase the risk of heart disease significantly, and quitting smoking can greatly reduce this risk over time.

Recognizing this, it is evident that the answer regarding the impact of cigarette smoking on coronary heart disease must be true, as overwhelming research consistently supports the notion that smoking adversely affects cardiovascular health.
