Increased incidence of myocardial infarction and stroke in hypertensive men with reduced lung function

J Hypertens. 2001 Feb;19(2):295-301. doi: 10.1097/00004872-200102000-00017.


Background and objective: Although hypertension is associated with increased cardiovascular risk, many individuals remain free from disease. This study is aimed to investigate whether this variation in individual susceptibility is associated with lung function.

Design: Population-based prospective cohort study.

Participants: 'Men born in 1914', Malmö, Sweden. Subjects (n = 639) were examined and considered free from prevalent cardiovascular disease at age 55 years.

Main outcome measures: Mortality, fatal and non-fatal stroke and cardiac events (fatal or non-fatal myocardial infarction) during 28-years follow-up.

Results: Of the men, 467 had normal blood pressure and 172 (27%) had hypertension (> or = 160/95 mmHg or treatment for hypertension). Hypertensive men with height-adjusted forced expiratory volume during 1 s (FEV1.0) below median had significantly higher rates of stroke (13.4 versus 5.8/1,000 person-years), cardiac events (27.1 versus 12.8/1,000 person-years) and all cause mortality (52.5 versus 28.6/1,000 person-years) than hypertensive men with high FEV1.0. These differences remained statistically significant after adjustment for potential confounders. Men with normal blood pressure and FEV1.0 below median had higher rates of stroke (5.4 versus 4.2/1,000 person-years), cardiac events (13.3 versus 11.6/1,000 person-years) and all cause mortality (29.9 versus 21.2/1,000 person-years) than men with normal blood pressure and high FEV1.0. After adjustments for potential confounders, FEV1.0 was significantly associated with mortality among men with normal blood pressure, whereas the associations with stroke and cardiac events did not reach significance.

Conclusion: The incidence of cardiovascular disease and death associated with hypertension is increased among men with reduced lung function. The synergistic interaction between hypertension and lung function was independent of smoking and other potential confounders.
