Hormones and Sexual Function Predict Outcomes in Revascularized Men With Diabetes (HEART-MEND)

2016年8月10日更新者：Icahn School of Medicine at Mount Sinai

The purpose of this study is to find out if androgen deficiency (low levels of testosterone, a male hormone produced by the sex glands) and erectile dysfunction (sexual dysfunction) will predict over time the development of a heart attack, stroke, or death in men with Diabetes Mellitus who have angiographically proven coronary artery disease (CAD) (≥50%) with or without percutaneous coronary intervention (PCI). A substudy aims to show the different factors and processes that may show a relationship between sexual function and levels of androgen in the body to heart disease.

详细说明

Diabetes mellitus (DM) and multi-vessel coronary artery disease (CAD) entail significant risk for progression of cardiac morbidity and mortality. Compelling recent research points to biological pathways that link DM and CAD to androgen status and sexual function. We hypothesize that androgen deficiency (AD) and erectile dysfunction (ED) independently serve as sentinel indicators, predicting the future development of adverse cardiovascular and cerebrovascular events in men with diabetes following coronary revascularization.

ED is emerging as a barometer of overall endothelial function. We hypothesize that as a consequence of this relationship, erectile dysfunction is predictive of cardiovascular outcomes in men with diabetes and CAD. We also propose that AD affects morbidity and mortality in men with DM and CAD by influencing presentation and progression of endothelial dysfunction as well as inflammation and hemostasis.

We propose to investigate four specific aims using 1,143 diabetic men who have angiographically proven coronary artery disease (CAD) (≥50%) in at least one major epicardial vessel with or without percutaneous coronary intervention (PCI). Specific aims of this study are: 1) To determine whether androgen status at baseline independently predicts primary and secondary endpoints in men (n=1,143) with DM and CAD. 2) To determine whether erectile dysfunction at baseline independently predicts cardiovascular outcomes in men with DM and CAD. 3) To determine whether change of androgen status and sexual function over time independently predict cardiovascular outcomes in men with DM and CAD. 4) To demonstrate specific mediators and pathways that link sexual function and androgen status to cardiovascular disease.

The primary endpoint is defined as the combined all-cause mortality, non-fatal myocardial infarction (MI), and stroke. Secondary endpoints include major adverse cardiovascular and cerebrovascular events (MACCE), defined as death, nonfatal MI, stroke or revascularization at one year and angina status as evaluated with the Seattle Angina Questionnaire (SAQ) at 6 months, 12 months, 18 months, 24 months, 30 months and 36 months following catheterization.

Signed and received copy of informed consent

Exclusion Criteria:

Severe congestive heart failure (class III or IV according to NYHA, or pulmonary edema) at the time of enrollment;
Previous stroke within 6 months;
Prior history of significant bleeding (within the previous 6 months) that might be expected to occur during PCI/DES related anticoagulation;
Acute ST-elevation MI (Q-wave) within 72 hours prior to enrollment requiring revascularization;
Abnormal creatine kinase (CK > 2x normal); or abnormal CK-MB levels at time of randomization;
Contraindication to either CABG or PCI/DES because of a coexisting clinical condition];
Significant leukopenia, neutropenia, thrombocytopenia, anemia, or known bleeding diathesis;
Intolerance or contraindication to aspirin or both clopidogrel and ticlopidine;
