Abstract:
Introduction:Erectile dysfunction (ED) has numerous links to cardiovascular disease. Numerous studies show the severity of ED is strongly associated with atherosclerosis and endothelial dysfunction implicated in the pathogenesis of coronary artery disease (CAD). These common vascular pathways have led to evidence that ED onset may be used as a marker of the severity of CAD as well as a preclinical marker of early onset-CAD. The researchers aim to determine the association of ED and CAD in terms of prevalence, clinical presentation and severity and extent of vessel involvement by SYNTAX score among CAD patients undergoing coronary angiography.
Methods:This is a prospective, cross sectional, analytical study design set at Perpetual Succour Hospital – Cebu Heart Institute, a private, tertiary hospital with cardiac specialty units located in Cebu City. This study includes all Filipino patients admitted at Perpetual Succour Hospital suspected to have coronary artery disease based on symptoms of angina, dyspnea or other anginal equivalent with indications to undergo coronary angiography during the period of October 1, 2014 to September 30, 2015 were included.
Results:A total of 160 patients were included in the study. The mean age is 57.23 years with most of the patients admitted for stable ischemic heart disease (SIHD) of 54.7%, non-ST elevation acute coronary syndromes (NSTEACS) 33.5% and ST-elevation myocardial infarction (STEMI) 11.8% with multiple cardiovascular risk factors like hypertension, diabetes mellitus, smoking and dyslipidemia. Eighty-two percent complained of ED symptoms with a mean International Index of Erectile Function (IIEF) score of 15.15. Most ED patients identified had mild to moderate ED (31.7%), mild ED (21.7%), moderate ED (17.4%) and severe ED (11.8%). There were only 17.4% of patients who had undergone coronary angiography for CAD complaints that had no ED symptoms on admission. Per clinical presentation, there was a significant association between patients presenting with severe ED, moderate ED and mild to moderate ED with those presenting with SIHD and ACS-NSTEMI on admission, moderate ED and mild to moderate ED. ED was significantly associated with obstructive CAD (p=0.001) and correlated directly with the number of vessels involved (p<0.01) and inversely related to SYNTAX scores (p<0.001). ED symptoms were noted to precede CAD diagnosis by 4.9 to 5.9 years.
Conclusion:In conclusion, there is a high prevalence of ED among CAD patients and its existence is significantly associated with obstructive CAD varying directly with extent and number of vessel involvement. There is a significant inverse relationship with severity of ED and SYNTAX scores. The existence of ED was present in all subsets of CAD patients, regardless of presentation of admission and preceded CAD symptoms and diagnosis by four to five years. - Full text:FINAL_2018-001_Association.pdf
