Testosterone levels in males with type 2 diabetes and their relationship with cardiovascular risk factors and cardiovascular disease

Abstract:

Introduction One of the factors involved in type 2 diabetes in males is a reduction in levels of testosterone, which has been shown to predict resistance to insulin and the development of cardiovascular diseases. Aim To assess the levels of testosterone in patients with type 2 diabetes and to evaluate their relationship with cardiovascular risk factors, peripheral arterial disease (PAD) and silent myocardial ischemia (SMI). Methods Total testosterone and sex hormone binding globulin were measured and free and bioavailable testosterones were calculated using Vermeulen’s formula. Levels of total testosterone ≥12 nmol/L or free testosterone >225 pmol/L were considered normal. PAD was evaluated using the ankle-brachial index. SMI was assessed using a baseline ECG, Doppler echocardiogram, 24-hour electrocardiogram (ECG) Holter, exercise stress …
