口服抗凝药一直是机械性主动脉瓣置换术的一个局限。本研究纳入了PROACT临床试验中的201名年龄≥18岁接受mAVR治疗的无血栓栓塞风险的患者,并将其随机分成DAPT治疗组(n=99)和标准的华法林联合阿司匹林治疗组(n=102),此为低风险组;另外,375名接受mAVR治疗且伴有1个或多个血栓栓塞风险的患者被随机分成低剂量华法林联合阿司匹林治疗组(n=185)和标准华法林联合阿司匹林治疗组(n=190),此为高风险组。结果显示,低风险组由于DAPT组过高的脑栓塞事件发生率而提前终止(3.12% vs 0.29%;p=0.02),但在出血和全因死亡率方面无明显差异。此外,高风险组患者的出血事件发生率明显更低,且两组在栓塞事件和全因死亡率方面无明显差异。本研究结果显示,在栓塞低风险的接受机械主动脉瓣置换术患者中,双重抗血小板药物会增加脑栓塞事件的发生风险。

目前,有关感染性心内膜炎(IE)在二叶主动脉瓣(BAV)和二尖瓣脱垂(MVP)患者中的情况信息甚少,且IE抗生素预防疗法(IEAP)在这些患者中是不推荐的。本研究的目的旨在评估BAV和MVP患者感染性心内膜炎的临床和微生物学特征,并评价IEAP对这些患者的潜在作用。本研究纳入了3208名来自西班牙31家医院的IE患者,并将其分成高风险且有IEAP指征的患者(高风险组,n=1226),中低风险无IEAP指征的患者(中低风险组,n=1839)和IE伴BAV(n=54)或MVP(n=89)组。分析结果显示,BAV或MVP伴IE患者发生草绿色链球菌感染的概率大于高风险组和中低风险组患者,另外,IE伴BAV或MVP患者发生心脏内并发症的概率大于中低风险组患者,与高风险组患者相似。本研究结果显示,感染性心内膜炎伴BAV或MVP患者发生草绿色链球菌感染和心脏内并发症的风险更大,应列于高风险IE组,且IE抗生素预防疗法的指征应重新修正。

许多侵入性医疗操作会引起菌血症,从而导致感染性心内膜炎的发生。本研究的目的旨在量化感染性心内膜炎与侵入性医疗和外科手术相关的过度风险。本研究纳入了1998年至2011年瑞典因感染性心内膜炎住院治疗的7013例患者,采用病例交叉设计,比较心内膜炎发生前12周内患者接受侵入性医疗操作的情况与其1年前相同12周内的操作情况。分析结果显示,许多心血管医疗操作,尤其是冠状动脉旁路移植术、皮肤和伤口处理的操作、输血、透析、骨髓穿刺、以及一些内窥镜特别是支气管镜检查,与感染性心内膜炎的发生呈强相关性。本研究结果显示,许多非牙科的侵入性操作会增加感染性心内膜炎的发生风险。

主动脉局限性内膜撕裂(LITs)是急性主动脉综合征(AAS)患者的常见形式,但LITs很难通过影像学手段提前检测。本研究的目的旨在比较和评估LITs与其他AAS在发病率、病理学特征、治疗和预后方面的差异。本研究纳入了2003年至2012年诊断的497名AAS患者,并将其分成经典解剖类型(AD)、壁内血肿、LITs、穿透性动脉粥样硬化溃疡和破裂胸主动脉瘤。分析结果发现,共有24例LITs患者(男性占16名,17名A型,7名B型),且患者年龄普遍大于AD患者,A型LITs患者的升主动脉扩张程度与AD患者相似。3名患者发生破裂,11名患者接受了急诊主动脉置换术,2名患者接受了血管内皮修复术。LITs患者的院内死亡率为4%(1/24),共有5名患者在出院后1.5年内相继死亡。另外,对所有LITs患者均进行了计算机断层成像检测,但仅1例LITs患者没有检测到最佳可视化的体积渲染图像。本研究结果显示,局限性内膜撕裂是急性主动脉综合征中较为罕见的类型,且临床特征和预后与经典解剖类型的AAS相似,通过高质量计算机断层成像检测可以对LITs进行早期诊断
