Erectile Dysfunction and Coronary Artery Disease: An Association of Higher Risk in Younger Men

INTRODUCTION The association between erectile dysfunction (ED) and coronary artery disease (CAD) has been described in various settings, but it is unclear if there is an independent interaction with age. AIM To investigate the interaction of age in the association between ED and CAD. METHODS This case-control study was conducted among 242 patients referred for elective coronary angiography. One hundred fourteen patients with significant CAD were identified as cases and 128 controls without significant CAD. ED was evaluated by the erectile function domain of the International Index of Erectile Function (IIEF) questionnaire, determined by a score ≤ 25 points. MAIN OUTCOME MEASURES Significant CAD was based on stenosis of 50% or greater in the diameter in at least one of the major epicardial vessels or their branches. The analysis was conducted in the whole sample and according to the age strata, controlling for the effects of cardiovascular risk factors, testosterone, and C-reactive protein. Results.  Patients had on average 58.3 ± 8.9 years. CAD and ED were associated exclusively in patients younger than 60 years (ED in 68.8% of patients with CAD vs. 46.7% of patients without CAD, P = 0.009). The association was independent of cardiovascular risk factors, testosterone and C-reactive protein (risk ratio 2.3, 95% confidence interval from 1.04 to 5.19). Severity of CAD was higher in patients younger than 60 years with ED. CONCLUSIONS Men with less than 60 years of age who report ED presented a higher risk of having chronic CAD and more severe disease diagnosed by coronary angiography.

Effects of nurse telesupport on transition between specialized and primary care in diabetic patients : study protocol for a randomized controlled trial

BackgroundAccording to the Global Diabetes Plan, a unified health system with preventive and educational strategies is essential to proper diabetes care and primary settings should be the main site of care. In Brazil, there is limited access to outpatient hospital diabetes services, while primary-care diabetes support is underutilized. Telemedicine can be a useful adjunct to support discharge of stable patients with type 2 diabetes to the primary care setting. In this paper, we present a randomized controlled trial (RCT) protocol designed to evaluate the effects of telehealth support for stable type 2 diabetes patients discharged from hospital outpatient diabetes clinics.MethodsWe designed a RCT. Patients with stable type 2 diabetes (glycated hemoglobin < 8%) considered eligible for discharge from specialized to primary care will be included. Those with uncontrolled ischemic heart disease, severe neuropathy, and stage IV/V nephropathy will be excluded. Enrolled patients will be randomized into two groups: follow-up supported by periodic phone calls by a nurse (intervention group) plus primary care or routine primary care only (control group). The intervention group will receive regular telephone calls (every three months for one year) and will have a toll-free number to call in case of questions about disease management. The main outcome measure is a comparison of glycemic control between groups (assessed by glycated hemoglobin) at one-year follow-up.DiscussionWe plan to evaluate the effectiveness of a telephone-based intervention on glycemic control in patients with type 2 diabetes followed by primary care teams. Telemedicine can be an important adjunct in type 2 diabetes management, improving patient education and knowledge about the disease. Furthermore, it can help the healthcare system by alleviating overload in specialized care settings and supporting the stewardship role of primary care.Trial registrationClinical Trials, NCT02768480.
