Video: The severity of LUTS is associated with an increase of Framingham CVD risk score

To determine the relationship between lower urinary tract symptoms (LUTS)/benign prostatic hyperplasia (BPH) and 10-year risk of cardiovascular disease (CVD) assessed by the Framingham CVD risk score in a cohort of patients without previous episodes of stroke and/or acute myocardial infarction.

From September 2010 to September 2014, 336 consecutive patients with BPH-related LUTS were prospectively enrolled. The general 10-year Framingham CVD risk score, expressed as percentage and assessing the risk of atherosclerotic CVD events, was calculated for each patient. Individuals with low risk had ≤10% CVD risk at 10 years, with intermediate risk 10–20% and with high risk ≥20%. Logistic regression analyses were used to identify variables for predicting a Framingham CVD risk score of ≥10% and moderate–severe LUTS (International Prostate Symptom Score [IPSS] ≥8), adjusted for confounding factors.

As category of Framingham CVD risk score increased, we observed higher IPSS (18.0 vs 18.50 vs 19.0; P < 0.05), high IPSS–voiding (6.0 vs 9.0 vs 9.5; P < 0.05) and worse sexual function. Prostate volume significantly increased in those with intermediate- vs low-risk scores (54.5 vs 44.1 mL; P < 0.05). Multivariate logistic regression analysis showed that intermediate- [odds ratio (OR) 8.65; P < 0.01) and high-risk scores (OR 1.79; P < 0.05) were independently associated with moderate–severe LUTS. At age-adjusted logistic regression analysis, moderate–severe LUTS was independently associated with Framingham CVD risk score of ≥10% (OR 5.91; P < 0.05).

Our cross-sectional study in a cohort of patients with LUTS–BPH showed an increase of more than five-fold of having a Framingham CVD risk score of ≥10% in men with moderate–severe LUTS.
