To investigate changes in the clinical characteristics, etiology and prognosis of prosthetic valve endocarditis at a tertiary-care hospital.
Retrospective cohort study of all patients diagnosed with prosthetic valve endocarditis using modified Duke criteria between 1986 and 2005. The analysis covered two time periods: January 1986 to December 1995 (P1) and January 1996 to December 2005 (P2).
In total, 133 episodes of endocarditis occurred in 122 patients. Of these, 73 (54.9%) were diagnosed in P1 and 60 (45.1%) in P2, with incidences of 2.19% and 2.18%, respectively. The patients' mean age (SD) was 52.6+/-16.6 years in P1 and 66.2+/-11.5 years in P2 (P=.0001). Clinical characteristics were similar in the two study periods. The increase in Enterococcus infection was remarkable (12.5% in P2 vs. 4.9% in P1; relative risk [RR]=2.5; 95% confidence interval [CI], 0.7-9.6), as was the decrease in viridans group Streptococcus infection (12.5% in P2 vs. 31.1% in P1; RR=0.4; 95% CI, 0.2-0.9). Some 90.4% of patients (63/73) underwent surgery in P1, while 68.3% (41/60) underwent surgery in P2. The difference was significant (RR=0.8; 95% CI, 0.6-0.9). The in-hospital mortality rate was 28.8% in P1 and 30% in P2 (RR=1; 95% CI, 0.6-1.7).
Changes in the epidemiology and microbiological etiology of prosthetic valve endocarditis were observed over the 20-year study period. Diagnostic and therapeutic approaches also changed, but mortality remained high.
研究一家三级护理医院中人工心脏瓣膜心内膜炎的临床特征、病因和预后的变化。
回顾性分析 1986 年至 2005 年间使用改良的 Duke 标准诊断为人工心脏瓣膜心内膜炎的所有患者的队列研究。分析涵盖两个时间段:1986 年 1 月至 1995 年 12 月(P1)和 1996 年 1 月至 2005 年 12 月(P2)。
共发生 133 例心内膜炎,122 例患者中 73 例(54.9%)为 P1 期,60 例(45.1%)为 P2 期,发病率分别为 2.19%和 2.18%。患者的平均年龄(SD)分别为 P1 期 52.6±16.6 岁和 P2 期 66.2±11.5 岁(P=0.0001)。两个研究期的临床特征相似。肠球菌感染显著增加(P2 期 12.5%,P1 期 4.9%;相对风险 [RR]=2.5;95%置信区间 [CI],0.7-9.6),而草绿色链球菌感染减少(P2 期 12.5%,P1 期 31.1%;RR=0.4;95%CI,0.2-0.9)。P1 期 90.4%(63/73)的患者接受手术治疗,P2 期 68.3%(41/60)的患者接受手术治疗,差异有统计学意义(RR=0.8;95%CI,0.6-0.9)。P1 期住院死亡率为 28.8%,P2 期为 30%(RR=1;95%CI,0.6-1.7)。
在 20 年的研究期间,观察到人工心脏瓣膜心内膜炎的流行病学和微生物病因学发生了变化。诊断和治疗方法也发生了变化,但死亡率仍然很高。
