Effect of environmental exposure to cigarette smoke on blood pressure in 24‑hour ambulatory blood pressure monitoring in patients with essential hypertension

78 nonsmoking patients with essential hypertension treated with hypotensive agents, mean age ~54 years, 41% men. Group 1 (n=39) was environmentally exposed to cigarette smoke, and Group 2 (n=39) was not exposed. Patients were matched for age, sex, BMI, hypertension duration and grade, and hypotensive treatment.

Environmental exposure to cigarette smoke (passive smoking) defined as being exposed in a closed space for at least an hour a day, staying for at least 30 minutes a day next to persons who smoke, or living with 1 or more smokers.

No environmental exposure to cigarette smoke (matched controls).
