BACKGROUND
Only a few previous studies have focused on the long-term prognosis of the patients with infective endocarditis (IE). Our purpose was to delineate factors potentially associated with the long-term outcome of IE, recurrences of IE and requirement for late valve surgery.
METHODS
A total of 326 episodes of IE in 303 patients were treated during 1980-2004 in the Turku University Hospital. We evaluated the long-term outcome and requirement for late valve surgery for 243 of these episodes in 226 patients who survived longer than 1 year after the initial admission. Factors associated with recurrences were analysed both for the 1-year survivors and for all 303 patients.
RESULTS
The mean (SD) follow-up time for the 1-year survivors was 11.5 (7.3) years (range 25 days to 25.5 years). The overall survival was 95%, 82%, 66%, 51% and 45% at 2, 5, 10, 15 and 20 years. In age and sex adjusted multivariate analyses, significant predictors for long-term overall mortality were heart failure within 3 months of admission (HR 1.97, 95% CI 1.27 to 3.06; p = 0.003) and collagen disease (HR 2.54, 95% CI 1.25 to 5.19; p = 0.010) or alcohol abuse (HR 2.39, 95% CI 1.30 to 4.40; p = 0.005) as underlying conditions, while early surgery was significantly associated with lower overall mortality rates (HR 0.31, 95% CI 0.17 to 0.58; p < 0.001). Heart failure was also significantly associated with the long-term cardiac mortality (p = 0.032). Of all 303 patients, 20 had more than 1 disease episode. Chronic dialysis (p = 0.002), intravenous drug use (p = 0.002) and diabetes (p = 0.015) were significant risk factors for recurrent episodes of IE, but when analysed separately for the 1-year survivors, only chronic dialysis remained significant (p = 0.017). Recurrences and late valve surgery did not confer a poor prognosis.
CONCLUSION
Heart failure during the index episode of IE was the complication, which significantly predicted a poor long-term outcome. Patients who underwent surgery during the initial hospitalisation for IE faired significantly better than those who did not.
背景
以往仅有少数研究关注感染性心内膜炎(IE)患者的长期预后。我们的目的是明确可能与IE长期预后、IE复发以及晚期瓣膜手术需求相关的因素。
方法
1980年至2004年期间,图尔库大学医院共治疗了303例患者的326次IE发作。我们评估了226例初始入院后存活超过1年的患者中243次发作的长期预后和晚期瓣膜手术需求。对1年幸存者和所有303例患者分析了与复发相关的因素。
结果
1年幸存者的平均(标准差)随访时间为11.5(7.3)年(范围25天至25.5年)。2年、5年、10年、15年和20年时的总生存率分别为95%、82%、66%、51%和45%。在年龄和性别校正的多变量分析中,入院后3个月内出现心力衰竭(HR 1.97,95%CI 1.27至3.06;p = 0.003)以及潜在疾病为胶原病(HR 2.54,95%CI 1.25至5.19;p = 0.010)或酒精滥用(HR 2.39,95%CI 1.30至4.40;p = 0.005)是长期总死亡率的显著预测因素,而早期手术与较低的总死亡率显著相关(HR 0.31,95%CI 0.17至0.58;p < 0.001)。心力衰竭也与长期心脏死亡率显著相关(p = 0.032)。在所有303例患者中,20例有不止1次发病。慢性透析(p = 0.002)、静脉吸毒(p = 0.002)和糖尿病(p = 0.015)是IE复发的显著危险因素,但对1年幸存者单独分析时,只有慢性透析仍然显著(p = 0.017)。复发和晚期瓣膜手术并未导致不良预后。
结论
IE首次发作时的心力衰竭是显著预测长期预后不良的并发症。在IE初始住院期间接受手术的患者比未接受手术的患者预后明显更好。
