在非梗阻性冠心病(NOCAD)心绞痛患者中,确定冠脉微血管功能不良(CMD)至关重要,且难度较高。心脏磁共振(CMR)可以较准确地评估心肌的灌注状态,并被广泛应用于诊断梗阻性冠心病。本研究的目的旨在评估CMRNOCAD心绞痛患者中的诊断价值。本研究纳入了50名心绞痛患者(65 ± 9岁)和20名年龄匹配的正常对照,对其进行腺苷负荷心脏磁共振检查,以评估左室功能、诱导性心肌缺血和梗塞情况。在接下来的7天时间内进行血管造影术,发现有28名患者出现梗阻性冠心病,22名患者出现NOCAD。在NOCAD患者中,微循环阻力(IMR)<25U患者的心肌灌注储备指数(MPRI)正常,而IMR25U患者的MPRI明显受损,与梗阻性冠心病患者缺血的心肌类似。在MPRI受损的NOCAD患者中,心肌血流在应激状态下的扩增也明显受损,静息状态下不变。研究结果显示,在非梗阻性冠心病伴心绞痛患者中,心脏磁共振能客观且非侵入性地评估微血管功能情况。

 

2. 体外循环冠脉搭桥术远期生存率要高于非体外循环

DOI: 10.1016/j.jacc.2017.12.049

 

我们在比较体外循环和非体外循坏冠状动脉旁路移植术(CABG)的临床效果时,常常忽视了两者远期疗效的差异,目前尚缺乏两者术后5年的疗效差异。本研究的目的旨在对体外循坏和非体外循环CABG的远期效果做一个荟萃分析。本研究对患者术后的死亡率、心梗发生率、心绞痛发生率、卒中发生率和血运重建进行了全面的评估。最终共纳入分析了来自6临床研究的8145名患者,死亡率在体外循环组是12.3%,在非体外循环组是13.9%,二者的比值比(OR)是1.1695% [CI] 1.02 -1.32 p = 0.03 13.9% vs. 12.3%)。此外,两者在心梗发生率、心绞痛发生率、卒中发生率和血运重建方面无明显差异。研究结果显示,体外循坏冠状动脉旁路移植术的远期生存率比非体外循环要更高。

 

3. 丙磺舒在治疗高龄痛风患者中心血管发生风险更小

DOI: 10.1016/j.jacc.2017.12.052

 

痛风患者发生心血管疾病的风险大大增高。本研究的目的旨在比较评估痛风患者接受的两者不同药物治疗(丙磺舒和别嘌呤醇)在心血管方面的安全性。本研究纳入了2008年至2013年年龄≥65岁服用丙磺舒或别嘌呤醇治疗的痛风患者,主要终点事件是心梗和卒中的复合住院治疗,次要终点事件是心梗、卒中、冠脉血运重建、心衰和死亡。最终,共纳入分析了9722名接受丙磺舒治疗的患者,29166名接受别嘌呤醇治疗的患者,平均年龄是76 ± 7岁,男性占54%。主要终点事件的发生率每100人年在丙磺舒治疗组中为2.36,在别嘌呤醇治疗组中是2.83,危险比(HR)是0.895% Cl 0.69-0.93)。此外,与别嘌呤醇治疗组相比,丙磺舒可以降低心梗、卒中、心衰和死亡率。研究结果显示,在高龄痛风患者的药物治疗中,丙磺舒在心血管安全性方面要更佳。

 

4. Fontan手术存活至成年的患者预后如何?

DOI: 10.1016/j.jacc.2017.12.054

 

对于存活至16岁及以上的接受Fontan手术患者的临床预后尚未阐明。本研究的目的旨在评估接受Fontan手术治疗的成年患者的临床预后。本研究纳入了澳大利亚和新西兰Fontan注册数据库(ANZFR)中年龄≥16岁的患者。最终共纳入分析了683名成年幸存者,有201名患者存在心房肺动脉(AP)交通,482名患者存在全腔静脉肺动脉交通。对于这些患者,30岁的存活率为90%95% CI 87%-93%),40岁的存活率为80%95% CI 75%-87%)。在存活至30岁的患者中,存在AP交通的患者预后要更差(p = 0.03)。在最近一次随访中,仅53%患者的纽约心功能分级为I级。此外,有136名(20%)患者经历过至少一次新发的心律失常,42名(6%)患者接受了永久起搏器治疗,45名(7%)患者出现了血栓栓塞事件,135名(20%)患者需要再次接受手术干预。在存活至40岁的患者中,仅41% (95% CI 33%-51%)的患者没有出现严重的不良反应。研究结果显示,在接受Fontan手术的成年患者中,并发症常见,并且死亡率不低,尤其在存在心房肺动脉交通的患者中。
