- Background There is growing evidence that erectile dysfunction is a sentinel for future coronary artery disease. Recently published studies have shown signs of impaired coronary endothelial function in patients with erectile dysfunction, without clinical cardiovascular disease and diabetes. We evaluated the magnitude of coronary vasodilatory dysfunction in men with erectile dysfunction, as compared with men with impaired glucose metabolism (impaired fasting glucose or diabetes) and healthy controls. Methods We investigated men aged 68-73 years with erectile dysfunction (n=12), age-matched men with impaired glucose metabolism, who all proved to have erectile dysfunction (n=15), and age-matched male controls (n=12). Erectile dysfunction was evaluated using the International Index of Erectile Function (IIEF)-5 questionnaire. Coronary flow velocity reserve in the left anterior descending artery was examined using Doppler ultrasound and intravenous adenosine provocation. Results Coronary flow velocities at rest did not differ between the three groups, but maximum coronary flow velocity was significantly lower in the erectile dysfunction group (P= 0.004) and in the impaired glucose metabolism group (P= 0.019), as compared with controls. There was no difference between the erectile dysfunction and impaired glucose metabolism groups. Coronary flow velocity reserve was reduced in the erectile dysfunction group (P=0.026) compared to controls, but was similar compared to the impaired glucose metabolism group. In multivariate analysis including all groups, erectile dysfunction score was the only independent predictor of reduced coronary flow velocity reserve (P=0.020). Conclusions The magnitude of early coronary endothelial and smooth muscle cell dysfunction in otherwise healthy men with erectile dysfunction was comparable to that of patients with impaired glucose metabolism: a well known risk factor for coronary artery disease.

- Aim: To investigate the impact of classical coronary heart disease (CHD) risk factors on the development of future erectile dysfunction (ED). Methods and results: A total of 830 randomly selected subjects were included. Baseline CHD risk factors were evaluated in relation to ED (evaluated by the International Index of Erectile Function-5 questionnaire) 25 years later. At follow-up, 499 men (60%) had some degree of ED. In age-adjusted logistic regression analysis, self-rated health [odds ratio (OR) 1.59, 95% confidence interval (CI): 1.09-2.31], family history of CHD (OR 1.75, CI: 1.17-2.61), fasting blood glucose (OR 1.52, CI: 1.14-2.02), triglycerides (OR 1.25, CI: 1.01-1.54), systolic blood pressure (SBP) (OR 1.19, CI: 1.04-1.35), body mass index (OR 1.08, CI: 1.03-1.13) and serum glutamyl transferase (GT) (OR 1.81, CI: 1.23-2.68), predicted ED. Independent predictors were higher age, low self-rated health, higher blood glucose, higher GT and a family history of CHD. Higher SBP was borderline significantly independent (p = 0.05). Furthermore, baseline age-adjusted Framingham risk score for CHD, also predicted future ED (OR 1.20, CI: 1.03-1.38). Conclusions: Our study supports and expands previous findings that ED and CHD share many risk factors, further underscoring the close link between ED and CHD. Men presenting with ED should be evaluated for the presence of other CHD risk factors.

- Abstract Objectives. Glucometabolic disturbances are associated with myocardial dysfunction. Brain natriuretic peptides (BNP) are used for detecting myocardial dysfunction in clinical practice. However, studies on elderly subjects and gender-specific analyses are sparse. Design. We examined cross-sectional associations between Nt-proBNP and 1) fasting plasma glucose (FPG), and 2) categories of glucometabolic disturbances, in middle-aged and older subjects (1266 men, 526 women), applying multivariate linear regression analysis. Results. FPG was positively correlated with Nt-proBNP among middle-aged men (p = 0.04) and negatively albeit non-significantly (p = 0.1) among middle-aged women. Weaker non-significant correlations were seen among older subjects. Middle-aged men with new-onset and prevalent diabetes had higher Nt-proBNP than the reference group (FPG ≤5.0 mmol/L): 9.53 (p = 0.002) and 8.23 (p = 0.02) vs. 5.71 pmol/L. No differences in Nt-proBNP between categories of glucometabolic disturbance were observed among older men or women. Conclusions. The results indicate an age- and gender difference in the ability of Nt-proBNP to identify myocardial dysfunction in relation to glucometabolic disturbances. Therefore, Nt-proBNP should be used with caution as a general surrogate marker for myocardial dysfunction in this setting.

- BACKGROUND: Left ventricular (LV) diastolic dysfunction has been associated with impaired glucometabolic status. However, studies of older subjects are lacking. We examined associations between echocardiographic indices of LV diastolic function and LV mass index (LVMI) and glucometabolic status among middle-aged and elderly subjects free from heart disease, hypothesizing that the associations would be comparative to younger cohorts.METHODS: We examined the Age Gene/Environment Susceptibility Reykjavik Study (Iceland; n = 607, 76 +/- 6 years) and the Malmö Preventive Project Re-Examination Study (MPP-RES) cohorts (Sweden; n = 1,519, 67 +/- 6 years), evaluating associations with multivariable regression analysis.RESULTS: In the Age Gene/Environment Susceptibility Reykjavik Study, LVMI was positively correlated with glycosylated hemoglobin (HbA1c) (P = .001). Otherwise, echocardiographic variables were not associated with glucometabolic status. In the MPP-RES, LVMI increased with increasing glucometabolic disturbance among both older (70-80 years) and middle-aged (57-69 years) subjects. Among older subjects, HbA1c was positively correlated with 2 variables reflecting LV diastolic function: late transmitral peak flow velocity (A) (P = .001) and early transmitral peak flow velocity (E)/early diastolic peak tissue velocity (Em) (P = .046). In middle-aged MPP-RES subjects, increasing glucometabolic disturbance was correlated with increasing late diastolic peak tissue velocity (Am) (P = .002) and, after age adjustment, with increasing A (P = .001) and decreasing Em/Am (P = .009). With age adjustment, Am and A were positively correlated with fasting glucose and HbA1c.CONCLUSIONS: Contrary to our hypothesis, in 2 independent cohorts of older individuals, associations between glucometabolic status and LV diastolic function were generally weak. These contrast with previous reports, as well as with observations among middle-aged subjects in the present study. Changes in LV diastolic function may be more age-related than associated with glucose metabolism in older subjects.

- Background: The increased risk of cardiovascular disease (CVD) in diabetic compared to non-diabetic subjects seems to decrease with age. Whether this age-related reduction applies to CVD risk factors, and whether it is limited to established diabetes mellitus (DM) or also applies to pre-diabetic conditions are not well known. Methods: Using a cross-sectional design we compared the strength of the correlation between glucometabolic disturbances (by grouping), CVD risk factor burden and self-rated health, in two age groups: middle-aged (57-69 years) and older (70-86 years) subjects, (63% men), participating in the Malmo Preventive Project Re-examination Study (n = 18,238). Simple (unadjusted) logistic regression analysis was applied to estimate between-group differences and trends. Interaction analysis was applied to estimate differences between age groups. Results: CVD risk factor burden and the proportion of subjects reporting poor self-rated health increased with increasing glucometabolic disturbance for men and women in both age groups (p-trend < 0.0001 for all). The slope of the trend curve with increasing CVD risk factor burden was significantly steeper for older women than for older men (p-interaction = 0.002). The slope of the trend curve for poor self-rated health was significantly steeper for middle-aged than for older men (p-interaction = 0.005), while no difference was observed between the age groups among women (p-interaction = 0.97). Conclusions: We found no reduction in risk factor accumulation with increasing glucometabolic disturbance between middle-aged and older subjects. Our results indicate life-long CVD risk factor clustering with increased glucometabolic disturbance, and suggest that previously observed age-related reduction in excess CVD risk for subjects with DM might be due to a survival bias. However, our observations indicate more pronounced risk factor clustering and worse self-rated health with increased glucometabolic disturbance in older women than in older men.
