Men with testosterone deficiency and a history of cardiovascular diseases benefit from long-term testosterone therapy: observational, real-life data from a registry study
BACKGROUND/OBJECTIVES
Long-term testosterone therapy (TTh) in men with hypogonadism has been shown to improve all components of the metabolic syndrome. In this study, we investigated the effects of long-term TTh up to 8 years in hypogonadal men with a history of cardiovascular disease (CVD).


PATIENTS AND METHODS
In two urological clinics observational registries, we identified 77 hypogonadal men receiving TTh who also had a history of CVD. The effects of TTh on anthropometric and metabolic parameters were investigated for a maximum duration of 8 years. Any occurrence of major adverse cardiovascular events was reported. All men received long-acting injections of testosterone undecanoate at 3-monthly intervals.


RESULTS
In 77 hypogonadal men with a history of CVD who received TTh, we observed a significant weight loss and a decrease in waist circumference and body mass index. Mean weight decreased from 114±13 kg to 91±9 kg, change from baseline: -24±1 kg and -20.2%±0.5%. Waist circumference decreased from 112±8 cm to 99±6 cm, change from baseline: -13±0.3 cm. Body mass index decreased from 37±4 to 29±3, change from baseline: -8±0.2 kg/m(2). Cardio-metabolic parameters such as lipid pattern, glycemic control, blood pressure, heart rate, and pulse pressure all improved significantly and sustainably. No patient suffered a major adverse cardiovascular event during the full observation time.


CONCLUSION
In men with hypogonadism, TTh appears to be effective in achieving sustained improvements in all cardiometabolic risk factors and may be effective as an add-on measure in the secondary prevention of cardiovascular events in hypogonadal men with a history of CVD.
