title: [Risk factors of erectile dysfunction in patients with cardiovascular diseases].
abstract: OBJECTIVE
  To investigate the penile erectile function of hospitalized male patients with cardiovascular diseases, the incidence of erectile dysfunction (ED) in this cohort, and the relationship of ED with cardiovascular diseases and its risk factors.
  
  
  METHODS
  Using a self-designed questionnaire, we conducted an investigation among the hospitalized patients in the Department of Cardiovascular Diseases of the First and Second Affiliated Hospitals of Xi'an Jiaotong University. We measured their body height, body mass index (BMI), waist circumference, hip circumference, and blood pressure, obtained their personal data, past history, metabolic indexes, and erectile function scores by IIEF-5, and analyzed the risk factors of ED using univariate and multivariate logistic regression and OR analyses.
  
  
  RESULTS
  Totally, 225 valid questionnaires were included in this investigation, which showed a 66.7% incidence of ED, 15.8% mild, 27.0% mild to moderate, 17.6% moderate, and 6.3% severe. The incident rates of ED in the 18-35 yr, 36-49 yr, 50-65 yr, and > 65 yr age groups were 13.6%, 39.1%, 89.2%, and 91.2%, respectively. Univariate logistic regression analysis manifested that the risk factors of ED in the patients with cardiovascular diseases included age (OR = 3.122, 95% CI 2.040-4.779), smoking (OR = 1.768, 95% CI 1.209-2.584), BMI (OR = 1.261, 95% CI 1.114-1.427), total cholesterol (OR = 1.77, 95% CI 1.339-2.340), TC/HDL (OR =1.715, 95% CI 1.349-2.181), hypertension (OR = 1.717, 95% CI 1.110-2.658), and coronary heart disease (OR = 2.235, 95% CI 1.169-4.275), while multivariate logistic regression analysis showed the risk factors to be age (OR = 4.99, 95% CI 2.264-10.998), financial condition, (OR = 2.804, 95% CI 1.127-6.976), smoking (OR = 2.109, 95% CI 1.179-3.772), BMI (OR = 1.414, 95% CI 1.136-1.760), and TC/HDL (OR = 2.001, 95% CI 1.016-3.943).
  
  
  CONCLUSIONS
  The incidence of ED is high in hospitalized patients with cardiovascular diseases and rises with the increase of age. Age, smoking, financial condition, BMI, and TC/HDL are the risk factors of both ED and cardiovascular diseases, and financial condition is closely associated with ED.
