Correlation of psychological factors with periodontal and erectile dysfunction diseases in coronary heart disease (CHD) patients

Studies have shown common risk factors between coronary heart diseases, periodontal and erectile dysfunction. The most important factors contributing to such diseases are psychological factors. The aim of this study was to determine the effect of psychological factors on correlation between periodontal diseases and erectile dysfunction in CHD patients. This descriptive-correlational study was carried out in 2014 in which 31 CHD male patients whom referred to Mehr Clinic in Tehran were selected by convenience sampling. Data were gathered by four questionnaires namely “Depression Anxiety Stress Scale”, “The International Index of Erectile Function”, “Florida Sexual History Questionnaire” and “CPD Self-Check Sheet”. The content validity of these instruments, based on their content validity were measured and reliability was confirmed using Cronbach’s alpha method. Data were analyzed by SPSS/19. In total, 74.2% of patients had organic and 25.8% had psychogenic erectile dys-function. In addition, no significant correlation was observed between periodontal disease and erectile dysfunction. Furthermore, only stress had an effect on this correlation. Results are showed that anxiety could predict the type of erectile dysfunction (P-value<0.05). There was no correlation between periodontal disease and erectile dysfunction in CHD patients. It is suggested that patients with both organic and psychogenic impotence, be evaluated for stress, anxiety and depression as well as periodontal disease with more compre-hensive questionnaires. Additionally, such study can be carried out on higher number of CHD patients to allow generalizability of the findings.
