Efeitos Terapêuticos da Tripla Antiagregação Plaquetária em Pacientes Femininas Idosas com Diabetes e Infarto Agudo do Miocárdio

BackgroundDual antiplatelet therapy (DAPT) is the cornerstone treatment of acute myocardial infarction (AMI).ObjectiveThe present study aimed to investigate the efficacy and safety of triple antiplatelet therapy (TAPT) in elderly female patients with diabetes and ST segment elevation myocardial infarction (STEMI), who had undergone percutaneous coronary intervention (PCI).MethodsWe designed a randomized, single-blind study. Control group A (97 elderly male patients with diabetes and STEMI, whose CRUSADE scores were < 30) received aspirin, ticagrelor, and tirofiban. A total of 162 elderly female patients with diabetes and STEMI were randomly divided into two groups according to CRUSADE score. Group B (69 patients with CRUSADE score > 31) received aspirin and ticagrelor. Group C (93 patients with CRUSADE score < 30) received aspirin, ticagrelor and tirofiban. P values < 0.05 were considered statistically significant.ResultsCompared to the findings in group A, post-PCI Thrombolysis in Myocardial Infarction (TIMI) grade 3 blood flow and TIMI myocardial perfusion grade 3 were significantly less prevalent in group B (p < 0.05). When compared to groups A and C, the incidence of major adverse complications was significantly higher in group B (p < 0.05).ConclusionTAPT could effectively reduce the incidence of major complications in elderly female patients with diabetes and STEMI. However, close attention should be paid to hemorrhage in patients receiving TAPT. (Arq Bras Cardiol. 2020; [online].ahead print, PP.0-0)     

改良内固定融合术治疗成人Ⅱ型痛性足副舟骨

目的探讨改良内固定融合术治疗成人Ⅱ型痛性足副舟骨（painful accessory navicular，PAN）的疗效。方法2016 年 1 月—2017 年 12 月，采用改良内固定融合术治疗 29 例（37 足）Ⅱ型 PAN。其中男 12 例，女 17 例；年龄 18～50 岁，平均 41.4 岁。扭伤 24 例，无明显诱因 5 例。患者均行 6 个月以上保守治疗，症状无明显改善。术前及末次随访时采用美国矫形足踝协会（AOFAS）中足评分评估临床疗效；X 线片测量跟骨倾斜角、距骨第 1 跖骨角、距舟关节包容角、距骨第 2 跖骨角。结果术后 1 例出现切口浅表感染，经加强换药后愈合；其余患者切口均Ⅰ期愈合，无深部感染或骨髓炎发生。29 例均获随访，随访时间 12～33 个月，平均 25.1 个月。X 线片示关节面均于术后 2～5 个月愈合，平均 3.4 个月。随访期间未见内固定物松动或断裂。末次随访时，AOFAS 疼痛、功能、力线评分及总分以及距舟关节包容角、距骨第 1 跖骨角和距骨第 2 跖骨角均较术前显著改善，差异有统计学意义（P<0.05）；跟骨倾斜角手术前后差异无统计学意义（t=1.097，P=0.276）。 结论采用改良内固定融合术治疗成人Ⅱ型 PAN 可有效缓解症状，患足功能恢复良好，并发症少。
