Heart failure with preserved ejection fraction-determinants and predictors of mortality, hospitalization and quality of life (analysis from a large heart failure registry). / CUHK electronic theses & dissertations collectionJanuary 2012 (has links)
近年,研究發現許多心臟衰竭患者的左室射血分數在正常範圍內。這種類型的心臟衰竭,已被稱為“射血分數保持的心臟衰竭(HFPEF)。研究還發現,HFPEF患者往往是老年女性,有高血壓病史,其預後比射血分數降低的心衰更好。 / 然而,很少人研究過中國人中HFPEF患者的死亡率。同時,經治療后HFPEF患者長期的生活質量是否改善沒有得到很好的研究,特別是在老年HFPEF患者中。此外,到目前為止,一直沒有一個風險評分系統用於預測HFPEF患者的預後。 / 我們從2006年至2010年在一所大學附屬醫院建立的心臟衰竭注冊研究中,前瞻性納入了847 名HFPEF的患者進行研究。此外,我們通過國際疾病分類第九版臨床修正(ICD-9- CM)代碼428進行數據檢索,回顧性分析了2001年至2005年入住我院的心臟衰竭的患者。其中170名射血分數超過50的患者納入本研究。爲了消除兩組病人基線差異對臨床終點的影響,我們計算出傾向性得分。在建立風險評分方面,所有HFPEF患者隨機分為推導組和驗證組。從推導組中,我們得到了風險評分,然後我們再在驗證組中測試評分系統是否可行。本研究中,生活質量是通過明尼蘇達州心力衰竭問卷(MLHFQ)進行評估。 / 我們研究的主要發現包括: / 1、與2001-2005年納入的HFPEF患者比,2006-2010年納入的HFPEF患者,一年生存率有顯著提高(76.9%比65.5%,P = 0.001),心臟衰竭的再次住院率也顯著下降(33.3%比50.6%,P <0.001)。傾向得分匹配調整後1年生存率提高(78.9%比68.1%,P = 0.02)和心衰再次住院率降低(34.3&比51.2%,P = 0.002)仍然顯著。 / 2、各個年齡組基線(32±16比30±15比34±11,P = 0.12)和12個月(16±14比16±12比19±13,P = 0.62)的MLHFQ得分均沒有顯著。HFPEF患者12個月時生活質量得到改善的比例在年齡組之間相似(84.0%比80.2%比87.5%,P = 0.68)。 / 3、我們通過Cox多因素回歸分析得到了了6個獨立的預測HFPEF患者1年死亡率的預後因素。每個因素根據其回歸系統獲得一個分數:低蛋白血症(5分),不使用鈣通道阻滯劑(3分),充血性心臟衰竭病史(2.5分),腦血管疾病病史(2.5分),尿素氮> 10mmol / L(2.5分),年齡> 78歲(2分)。每一個患者根據風險分數而被分為三個危險人群:低風險(0至5.5分),中等風險(10.5分)和高風險(11至17.5分)。在推導隊列,這三組的1年死亡率分別為10.5%,22.3%和48.7%分別。在驗證隊列,相應的死亡率分別為15.4%,25.3&和39%。 / 4、低蛋白血症為HFPEF患者1年死亡率的最有力的預測指標。 / 綜上所述,我們發現,近年來,HFPEF患者一年的死亡率和心臟衰竭再次住院率有所下降。與相對年輕的HFPEF患者相比,老年HFPEF患者經歷了類似的生活質量的改善。從臨床常用的變量得到的風險評分可用於預測HFPEF患者1年死亡率。低蛋白血症為HFPEF患者1年死亡率的最有力的預測指標。 / Recently, many studies have found that many patients presenting with clinical heart failure (HF) had a left ventricular ejection fraction in the normal range. This entity has been termed “heart failure with preserved ejection fraction (HFPEF). Previous studies have indicated that patients who have HFPEF tend to be older, female, and to have a history of hypertension. / However, little was known about the clinical outcome and related predictors of HFPEF patients in Chinese population. Long term quality of life (QOL) after treatment in HFPEF patients have not been well studied, especially in very elderly HFPEF. Furthermore, there has been no a risk score used HFPEF patients. / We studied 847 HFPEF patients who were prospectively enrolled into a HF Registry from 2006 to 2010 at a teaching hospital. In addition, a historical cohort of patients admitted in our hospital from 2001 to 2005 was retrospectively retrieved and data searched using the ICD-9-CM code 428. Among this, 170 with HFPEF were selected for study. To adjust for the impact of baseline differences between the 2 cohorts on clinical outcomes, we calculated a propensity score. To establish a risk score, HFPEF patients were randomly divided into derivation group and validation group. We got a risk score from the derivation group and then checked in the validation one. QOL was assessed by the Minnesota Living with Heart Failure Questionnaire (MLHFQ) instruments. / Main findings of our study included: / 1. 1-year survival rates improved (65.5% vs. 76.9%, p=0.001) and HF re-hospitalization rates decreased (50.6% vs. 33.3%, p<0.001 in HFPEF patients admitted between 2001-2005 and 2006-2010, respectively). The improvement in 1-year survival (68.1% vs. 78.9%, p=0.02) and HF re-hospitalization (51.2% vs. 34.3%, p=0.002) remained significant after propensity score matching. / 2. Baseline (30±16 vs. 28±16 vs. 29±16, p=0.87) and 12-months (15±14 vs. 16±14 vs. 15±12, p=0.92) MLHFQ score showed no significant differences with advancing age. Proportion of patients who experienced improvement in QOL at 12-months were similar among age groups (84.0% vs. 80.2% vs. 87.5%, p=0.68). / 3. Six independent prognostic factors were identified, and each was assigned a number of points proportional to its regression coefficient: hypoalbuminemia (5 points), not use of CCB (3 points), history of HF (2.5 points), history of CVD (2.5 points), BUN>10mmol/L (2.5 points), age>78 years (2 points). Wecalculated risk scores for each patient and defined three risk groups: low risk (0 to 5.5 points), intermediate risk (6 to 10.5 points) and high risk (11 to 17.5 points). In the derivation cohort, the 1-year mortality rates for these three groups were 10.5%, 22.3%, and 48.7% respectively. In the validation cohort, the corresponding mortality rates were 15.4%, 25.3% and 39%. / 4. Hypoalbuminemia was the most powerful predictor of 1 year mortality for HFPEF patients. / In summary, we found that the mortality of HFPEF patients in the first year decreased over time. Elderly HFPEF patients experienced similar improvements in QOL compared to younger ones. The clinical based risk score can be used to predict mortality of HFPEF patients. Hypoalbuminemia was the most powerful predictor of 1 year mortality for HFPEF patients. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Liu, Ming. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2012. / Includes bibliographical references (leaves 124-150). / Electronic reproduction.
