title: [Influence of blood pressure lowering treatment on IPSS, Qmax in old and middle-aged male patients with essential hypertension].
abstract: OBJECTIVE
  To explore the influence of blood pressure lowering treatment on the International Prostate Syndrome Score (IPSS) and maximum flow rate (Qmax) in old and middle-aged male patients with essential hypertension.
  
  
  METHODS
  We enrolled 193 hypertensive male patients aged 50-75 years from the rural area of Anqing, Anhui, treated them with Amlodipine for 4 weeks, and then analyzed the correlation of their baseline blood pressure and reduced blood pressure with the changes of IPSS and Qmax.
  
  
  RESULTS
  After 4 weeks of medication, the systolic blood pressure (SBP) and diastolic blood pressure (DBP) of the subjects dropped by 16.8 +/- 16.7 and 8.1 +/- 7.7 mmHg respectively (P < 0.01), IPSS decreased by 2.5 +/- 5.5 points (P < 0.01) and Qmax increased by 0.2 +/- 4.7 ml/s (P = 0.46). Changes of Qmax were not significantly correlated with either the baseline or decreased blood pressure, while changes of IPSS had a significant linear correlation with the former but not with the latter.
  
  
  CONCLUSIONS
  Lowering blood pressure in old and middle-aged male patients with essential hypertension can prevent or alleviate the subjective symptoms of benign prostatic hyperplasia, and it reduces IPSS more significantly in those with higher baseline blood pressure.
