Background The benefit of statin use after acute ST-segment elevation myocardial infarction （STEMI） has been well established, however, the influence of the timing of statin administration has not been elucidated. The objective of this study focused on early clinical outcomes after percutaneous coronary intervention （PCI）. Methods This analysis of the Korea Working Group on Myocardial Infarction registry （KorMI） study included 3,584 STEMI patients （mean age, 63 ±13 years;male, 2,684, 74.9%） undergoing PCI from January 2008 to June 2009. Rates of major adverse cardiac events （MACE：all-cause death, recurrent MI, and target lesion revascularization） were compared among patients grouped according to statin therapy timing：I, both during and after hospitalization （n=2,653, 74%）;II, only during hospita-lization （n=309, 8.6%）;III, only after discharge （n=157, 4.4%）;and IV, no statin therapy （n=465, 13%）. Mean follow-up duration was 234 ± 113 days. Results Multivariate factors of statin use during hospitalization included prior statin use, multiple diseased vessels, final thrombolysis in myocardial infarction flow grade III, and low-density lipoprotein cholesterol level. At 6-month follow-up, groups Ⅲ and Ⅳ had the highest MACE rates （2.3%, 3.9%, 5.1%, and 4.9%for groups I-IV, respectively, P=0.004）. After adjusting for confounders, groups Ⅱ-Ⅳ had a higher MACE risk than group Ⅰ [hazard ratio （HR）：3.20, 95%confidence interval （95%CI）：1.31-7.86, P=0.011;HR：3.84, 95%CI：1.47-10.02, P=0.006;and HR：3.17, 95%CI：1.59-6.40, P=0.001;respectively]. Conclusions This study, based on the national registry database, shows early and continuous statin therapy improvs early outcomes of STEMI patients after PCI in real-world clinical prac-tice.

Are prostatic calculi independent predictive factors of lower urinary tract symptoms？

引用

Asian Journal of Andrology 2010年第2期12卷 221-226页

作者： Sung-Woo Park Jong-Kil Nam Sang-Don lee Moon-kee Chung Medical Research Institute and Department of Urology Pusan National University Yangsan Hospital Yangsan 626-770Korea

We determined the correlation between prostatic calculi and lower urinary tract symptoms （LUTS）,as well as the predisposing factors of prostatic calculi. Of the 1 527 patients who presented at our clinic for LUTS,802underwent complete evaluations,including transrectal ultrasonography,voided bladder-3 specimen and international prostatic symptoms score （IPSS）. A total of 335 patients with prostatic calculi and 467 patients without prostatic calculi were divided into calculi and no calculi groups,respectively. Predictive factors of severe LUTS and prostatic calculi were determined using uni/multivariate analysis. The overall IPSS score was 15.7±9.2 and 14.1±9.1 in the calculi and no calculi group,respectively （P = 0.013）. The maximum flow rate was 12.1±6.9 and 14.2±8.2 mL s^（-1） in the calculi and no calculi group,respectively （P = 0.003）. On univariate analysis for predicting factors of severe LUTS,differences on age （P = 0.042）,prostatic calculi （P = 0.048） and prostatitis （P = 0.018） were statistically significant. However,on multivariate analysis,no factor was significant. On multivariate analysis for predisposing factors of prostatic calculi,differences on age （P〈0.001） and prostate volume （P = 0.001） were significant. To our knowledge,patients who have prostatic calculi complain of more severe LUTS. However,prostatic calculi are not an independent predictive factor of severe LUTS. Therefore,men with prostatic calculi have more severe LUTS not only because of prostatic calculi but also because of age and other factors. In addition,old age and large prostate volume are independent predisposing factors for prostatic calculi.
