Cardiac training improves sexual function, erectile performance in CHD patients
A decrease in blood pressure caused by cardiac training improves erectile performance in patients with coronary heart disease (CHD), a recent study has shown.
Researchers recruited 101 men (mean age 59.50±7.93 years) with erectile dysfunction and who were treated invasively for CHD. For 5 days per week, cardiac rehabilitation was performed with the following components: 2 days of gym workouts and 3 days of cycle ergometer exercises. Training was conducted over 6 months.
Cardiac rehabilitation produced a significant change in baseline systolic blood pressure (SBP; 130.2±112 to 125.2±9.2 mm Hg; mean change, 5.1±3.1 mm Hg; p<0.001) and diastolic blood pressure (DBP; 81.9±5.1 to 80.3±5.1 mm Hg; mean change, 1.6±1.5 mm Hg; p<0.001).
The change in SBP was associated with interventricular septum end-diastolic diameter (p=0.024), hypertension (p=0.000) and the use of angiotensin-converting enzyme inhibitor/angiotensin receptor blockers (ACEIs/ARBs; p=0.000).
Similarly, hypertension (p=0.023) and the use of ACEIs/ARBs (p=0.000) were significantly correlated with the change in DBP values. As expected, baseline SBP and DBP values had a significant impact on the change in values following cardiac rehabilitation (p=0.000 for both).
Median scores in the International Index of Erectile Function 5 questionnaire score increased significantly after cardiac rehabilitation (15 to 18 points; p<0.001).
“After excluding patients with diabetes, a greater decrease in SBP was found to be significantly associated with greater improvement in erectile performance. This effect is the strongest in patients with hypertension and those with dyslipidaemia,” researchers noted.
