Obesity and metabolic features associated with long-term developing diastolic dysfunction in an initially healthy population-based cohort.
Diastolic dysfunction (DD) is increasingly common. However, its metabolic determinants are poorly known. This study aims to determine which metabolic and inflammatory features predict DD in initially healthy adults.. We prospectively analyzed the association between metabolic features and DD in 728 initially healthy adults aged 30-60 from Eastern France enrolled in the STANISLAS population-based cohort. Clinical and biological cardiovascular features were collected at baseline (1994-1995). DD was assessed twenty years later (2011-2016) by echocardiography using current international guidelines. For replication purposes, 1463 subjects from the Malmö Preventive Project cohort were analyzed.. In the STANISLAS cohort, 191 subjects (26.2%) developed DD. In age-sex-adjusted logistic models, significant predictors of DD were body mass index (BMI, odds ratio for 1-standard-deviation increase (OR) 1.28, 95% CI 1.08-1.52), waist circumference (WC, OR 1.48, 95% CI 1.18-1.84), waist-hip ratio (OR 1.53, 95% CI 1.16-2.02), systolic blood pressure (OR 1.19, 95% CI 1.00-1.43) and triglycerides (TG, OR 1.18, 95% CI 1.00-1.40). Subjects with elevated WC (> 80th percentile) and TG (> 50th percentile) had a twofold higher DD risk (age-sex-adjusted odds ratio 2.00, 95% CI 1.20-3.31, P = 0.008), whereas no such interplay was observed for BMI. In the Malmö cohort, BMI was similarly associated with DD; participants with both elevated BMI and TG were at higher DD risk (age-sex-adjusted odds ratio 1.61, 95% CI 1.18-2.20, P = 0.002).. Subjects with elevated WC and TG may have a higher long-term DD risk. Prevention targeting visceral obesity may help reduce the incidence of DD.

Effects of sulphydryl- and non-sulphydryl-containing ACE inhibitors on left ventricular relaxation in the isolated guinea pig heart.
ACE inhibitors exert both acute and chronic beneficial effects on cardiac function (e.g remodelling, diastolic dysfunction). We have previously reported that the ACE inhibitor captopril induces selective left ventricular (LV) relaxant effects in the isolated ejecting guinea pig heart. The aim of the present study was to further investigate the mechanism of the captopril-induced changes in early LV relaxation by comparing the effects of two sulphydryl and two non-sulphydryl containing ACE inhibitors in the same experimental preparation. Isolated ejecting guinea pig hearts were studied under conditions of constant loading and heart rate. LV pressure was monitored by a 2F micromanometer-tipped catheter transducer inserted in the LV cavity. The sulphydryl-containing ACE inhibitors captopril and zofenaprilat enhanced early LV relaxation, whereas the non-sulphydryl-containing ACE inhibitors lisinopril and quinaprilat did not. The effects of captopril and zofenaprilat were attenuated both by the nitric oxide-scavenger haemoglobin and the bradykinin B2-kinin receptor antagonist HOE 140. Neither the oxygen free-radical scavenger superoxide dismutase nor the sulphydryl-containing compound N-acetyl cysteine administered together with lisinopril had any effect on LV relaxation. These data demonstrate that inhibition of intra-cardiac ACE activity may acutely modulate LV relaxation through increased activity of the bradykinin-nitric oxide pathway. The presence of a sulphydryl group on the relevant ACE inhibitor appears to be essential for this LV relaxant effect.
