Secondary prevention of coronary heart disease in women and men in Germany from 1997-1999 and from 2008-2011-Trend analysis with two national health population surveys

Abstract

The benefit of medicines in the secondary prevention of coronary heart disease (CHD) has been demonstrated in women and men. However, gender-specific differences have been observed in the prescription of these medicines. Information on trends in prevalence use in women and men from population-based studies are still lacking. Data of people aged 40-79years with CHD from the national health interview and examination surveys for adults in Germany from 1997-1999 (GNHIES98, n = 411) and from 2008-2011 (DEGS1, n = 440) were analyzed. Trend analyses via multivariable regression models, taking into account relevant covariables, were used to calculate the prevalence of medicine use in secondary prevention of CHD between GNHIES98 and DEGS1. The following groups were considered: antiplatelet, statins, beta-receptor blockers, agents acting on the renin-angiotensin system (RAS blocker), calcium-channel blockers, and nitrate. In one decade, the prevalence had increased for antiplatelet (24.0% vs. 59.6%), statins (18.5% vs. 56.2%), beta-receptor blockers (24.7% vs. 65.5%), and RAS blockers (31.6% vs. 69.0%). The prevalence of calcium-channel blockers (33.3% vs. 20.5%) and nitrate (40.6% vs. 10.1%) had decreased. In GNHIES98, men were more likely to use RAS blockers. Significant gender differences were found in DEGS1 only for angiotensin-converting-enzyme (ACE) inhibitors. This study showed an improvement in the use of drugs for the secondary prevention of CHD in both sexes.
