[Smoking and blood pressure: A complex relationship]

Area of Science:

• Cardiovascular Medicine
• Public Health

Background:

• Hypertension and tobacco smoking are primary modifiable risk factors for atheromatous disease and its cardiovascular complications.
• Smoking impacts stroke risk (hypertension) and coronary events, aortic aneurysms, and peripheral artery disease more profoundly.

Purpose of the Study:

• To elucidate the multifaceted impact of tobacco smoking on hypertension and cardiovascular disease.
• To highlight the role of smoking in accelerating arterial aging and contributing to hypertension.
• To emphasize the importance of smoking cessation in managing cardiovascular risk.

Main Methods:

• Review of existing literature on the physiological effects of smoking on blood pressure regulation.
• Analysis of smoking's influence on autonomic nervous system activity, arterial aging, and metabolic factors.
• Examination of smoking's contribution to renal artery stenosis and its effect on antihypertensive medication efficacy.

Main Results:

• Smoking transiently alters blood pressure regulation via the autonomic nervous system and accelerates arterial aging.
• Chronic sympathetic activation from smoking affects lipid metabolism and insulin resistance, contributing to atheromatous disease.
• Smoking can lead to renal artery stenosis, worsen hypertension, and reduce the effectiveness of antihypertensive drugs, often coexisting with alcohol consumption.

Conclusions:

• Tobacco smoking is a significant contributor to poor blood pressure control and cardiovascular complications.
• Smoking cessation is an effective intervention for all patients, irrespective of age or smoking duration.
• Supporting smoking cessation is vital, as exemplified by initiatives like the French 'Plan Sans Tabac'.
