Relationship between lower urinary tract symptoms and cardiovascular risk scores including Framingham risk score and ACC/AHA risk score

AimsThis study attempted to investigate the association between lower urinary tract symptoms (LUTS) and cardiovascular disease (CVD) risk using International Prostate Symptom Score (IPSS) and CVD risk scores and to overcome the limitations of previous relevant studies. MethodsA total of 2994 ostensibly healthy males, who participated in a voluntary health check in a health promotion center from January 2010 to December 2014, were reviewed. CVD risk scores were calculated using Framingham risk score and American College of Cardiology (ACC)/American Heart Association (AHA) score. Correlation and multivariate logistic regression analysis to predict the CVD risk severity were performed. ResultsCorrelation between total IPSS with CVD risk scores demonstrated significant positive associations, which showed higher correlation with ACC/AHA score than the Framingham score (r=0.18 vs 0.09, respectively). For ACC/AHA score, the partial correlation after adjustment of body mass index (BMI) showed significant positive correlations between all LUTS parameters and PSA. For the Framingham score, all variables, except IPSS Q2 and IPSS Q6, showed significant positive correlations. After adjustment of BMI, prostate volume and PSA, only the severe LUTS group showed significant relationship with intermediate-high CVD risk severity, as compared with normal LUTS group (OR=2.97, 95%CI (1.35-6.99)). ConclusionUsing two validated CVD risk calculators, we observed that LUTS is closely associated with future CVD risk. To predict the intermediate-high CVD risk severity, severe LUTS was a sentinel sign, the presence of which warrants the importance of an earlier screening for CVD.
