Insights
Coronary artery bypass graft (CABG) surgery positively impacts erectile dysfunction (ED) in patients with coronary artery disease (CAD). This study found improvements in ED after on-pump CABG, suggesting a beneficial effect on sexual health.
Area of Science:
- Cardiovascular Surgery
- Urology
- Sexual Health
Background:
- Erectile dysfunction (ED) is prevalent in cardiovascular disease (CVD) patients.
- ED is a recognized complication following coronary artery bypass graft (CABG) surgery.
- This study investigated ED status in coronary artery disease (CAD) patients pre- and post-CABG.
Purpose of the Study:
- To evaluate the impact of on-pump CABG on erectile function in male patients with CAD.
- To assess changes in the severity of erectile dysfunction before and after CABG surgery.
Main Methods:
- Prospective cohort study of male patients undergoing elective on-pump CABG.
- Data collected using the International Index of Erectile Function (IIEF-5) questionnaire at baseline and 6 months post-surgery.
- ED severity categorized as normal, mild to moderate, or moderate to severe based on IIEF scores.
Main Results:
- 426 male patients participated; mean age 58.69 years.
- Significant improvement in mean IIEF-5 scores post-CABG (13.95±5.44 vs. 14.20±5.69, P=0.001).
- A shift in ED severity distribution was observed 6 months post-surgery (P=0.01).
Conclusions:
- On-pump CABG surgery demonstrates a positive effect on improving erectile function.
- The findings suggest CABG may benefit sexual health in patients with CAD.
- Further research can explore mechanisms and long-term effects.
Background:
Erectile dysfunction (ED) is common in cardiovascular disease (CVD) and indicates a complication of coronary artery bypass graft surgery (CABG). This study was designed to evaluate the status of erectile dysfunction in patients with CAD before and after CABG surgery.
Methods:
We designed a prospective cohort study on male patients candidates for elective on-pump CABG between June 2006 to October 2012 in 3 hospitals in Sari, Iran (Fatemeh Zahra, Shafa and Nime-Shaban Hospitals). Patient's primary data were collected based on the International Index of Erectile Function questionnaire (IIEF-5) at baseline 6 months after surgery. The severity of dysfunction was categorized as, normal, mild to moderate and moderate to severe based on IIEF score.
Results:
Four hundred twenty-six male patients with mean age of 58.69±12.49 years participated in this study. 166 patients had DM (38.96%) 230 patients had hypertension (54%). 307 patients had three-vessel impairment (72.07%) and 119 patients with one or two vessel impairment (27.93%). The 15.02%, 18.07%, 23%, 31.92% and 11.97%, at baseline changed to 16.90%, 19.95%, 23.71%, 32.22% and 8.21%, at endpoint (P=0.01). Also, the mean±SD of IIEF-5 score before and after surgery was 13.95±5.44 and 14.20±5.69, respectively (P=0.001).
Conclusion:
The result of our study shows that on-pump CABG surgery has a positive effect on the improvement of erectile dysfunction 6 months after surgery.
