【摘要】 目的 探討2型糖尿病(T2DM)胰島素抵抗導致糖尿病性心功能不全的臨床表現特點及相關激素的改變。 方法 2008年1-4月對T2DM患者35例(胰島素抵抗指數HOMA-IRlt;2.69者19例為A1組,HOMA-IR≥2.69者16例為A2組)及健康體檢者20人B組測體重指數(BMI)、空腹血糖(FPG)、胰島素、心鈉素(ANP)、腦鈉素(BNP)水平;心臟彩色多普勒超聲分別測E/A、e/a、S/D、LVEF、DT期。 結果 A2組BMI較A1、B組均明顯增加(Plt;0.05),A1、B組間差異無統計學意義(Pgt;0.05)。ANP、BNP及DT值在A1、A2組均較B組增高(Plt;0.05),BNP在A2組高于A1組(Plt;0.05),ANP、DT值在A1、A2組間差異均無統計學意義(Pgt;0.05)。E/A、e/a和S/D在A1、A2組均較B組降低(Plt;0.05),A1、A2組間差異均無統計學意義(Pgt;0.05)。A2組患者LVEF較A1、B組均明顯降低(Plt;0.05),A1、B組間差異無統計學意義(Pgt;0.05)。 結論 隨著胰島素抵抗加重,心肌舒張順應性較差和收縮力下降,伴隨相關激素(心臟利鈉肽)分泌增加,最終產生心功能不全的臨床表現、體征及多普勒超聲心動圖表現。【Abstract】 Objective To investigate the clinical features and related hormone changes of diabetic cardiac insufficiency leaded by insulin resistance in type 2 diabetes mellitus (T2DM). Methods From January to April 2008, 35 patients with T2DM (group A1: HOMA-IRlt;2.69, n=19; group A2: HOMA-IR≥ 2.69, n=16) and 20 subjects without T2DM (group B) were enrolled. The body mass index (BMI), fasting plasma glucose (FPG), insulin (FINS), atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), and E/A, e/a, S/D, LVEF and DT stage of all subjects were detected. Results The BMI in group A2 was higher than those in group A1 and group B (Plt;0.05), while the difference between the later two groups was not statistically significant (Pgt;0.05). The ANP, BNP and DT stage were all higher than those in group B (Plt;0.05), the BNP was higher in group A2 than in group A1 (Plt;0.05), while the difference of neither ANP nor DT stage between the later two groups was statistically significant (Pgt;0.05). The values of E/A, e/a and S/D in group A1 and A2 were all lower than those in group B (Plt;0.05), while there were no statistically significant diferences between group A1 and A2 (Pgt;0.05). The values of LVEF of group A1 and A2 were both significantly reduced than that in group B (Plt;0.05), and the values in group A2 were the lowest (Plt;0.05). Conclusion With the aggravating of insulin resistance, myocardial contractility and diastolic function will decline, meanwhile the ANP and BNP secretion will increase, and then the clinical and echocardiographic manifestation will appear.
分析心功能不全冠心病患者施行非體外循環冠狀動脈旁路移植術(OPCAB)的臨床資料,探討其手術風險,提出治療方案。 方法 將2004年1月至2008年6月首都醫科大學附屬北京安貞醫院66例冠心病患者,按心功能不同分為3組,每組22例,組1:男18例,女4例;年齡55.3±9.1歲;術前左心室射血分數(LVEF)lt;30%;組2:男19例,女3例;年齡55.5±10.2歲;30%≤LVEFlt;40%;組3:男17例,女5例;年齡55.8±8.7歲;LVEF≥40%;組2和組3作為對照。觀察圍術期臨床資料包括術前調整時間、移植血管支數、同期室壁瘤手術、呼吸機輔助呼吸時間、主動脈內球囊反搏(IABP)使用時間、住ICU時間、強心藥種類、術后住院時間和住院費用等的改變。 結果 術后無死亡和嚴重并發癥發生,均痊愈出院。組1術前調整時間(18.9±14.6 d vs. 10.8±7.4 d,P=0.023)、使用IABP例數(7 vs.1, P=0.012)、住ICU時間(3.0±0.7 d vs. 1.2±0.6 d,P=0.008)、強心藥種類(1.6±0.7種 vs. 1.0±0.2種,P=0.000)、術后住院時間(17.4±12.1 d vs. 11.8±34 d,P=0.038)和住院費用(11.4±5.2萬元 vs. 7.6±1.7萬元,P=0.007)均多于組3,兩組比較差異均有統計學意義。3組患者均獲得隨訪,隨訪時間3~6個月,均生存,隨訪期間無明顯心絞痛發作。 結論 心功能不全患者行OPCAB手術安全,但所需醫療資源多,須慎重選擇。
