Abstract

OBJECTIVES:Persons living with HIV (PLWH) are at greater risk for acute coronary syndrome (ACS). Practice patterns of ACS management by HIV serostatus are unknown. We examined the presentation and management of ACS in PLWH. DESIGN:Retrospective case-control study. METHODS:We included 86 PLWH and 263 sex-matched and race-matched HIV-negative controls hospitalized with ACS between 2004 and 2013. We performed multivariable conditional logistic regression to determine the associations between HIV serostatus and ACS type and management. RESULTS:Both groups were predominantly of black race and male sex. PLWH were significantly younger (53 vs. 60 years) and more likely to smoke (48 vs. 31%). Among PLWH, 30% had CD4 cell count less than 200 cells/μl and 58% had undetectable HIV RNA. PLWH had more single-vessel disease and a higher median Gensini score among those with single-vessel disease (32 vs. 4.25) than controls. HIV serostatus was positively associated with ST-elevation myocardial infarction (STEMI) [adjusted odds ratio (aOR) (95% confidence interval (CI)):5.05 (1.82-14.02)], and any revascularization procedure after ACS [aOR (95% CI): 2.90 (1.01-8.39)] and negatively associated with non-STEMI [aOR (95% CI): 0.33 (0.14-0.79)] presentation. PLWH who underwent stent placement had a higher likelihood of bare metal stent placement compared with controls [70 vs. 15%, aOR (95% CI): 5.94 (1.33-26.55)]. Among PLWH, ACS characteristics were not significantly associated with CD4 cell count, HIV RNA, or antiretroviral therapy. CONCLUSION:PLWH hospitalized with ACS were more likely to have severe single-vessel disease, present with STEMI rather than non-STEMI, and undergo revascularization, and less likely to have a drug-eluting stent placed than matched HIV-negative controls, suggesting that coronary plaque morphology and/or distribution is different with HIV infection and warrants further investigation.

摘要

目的: HIV 感染者 (PLWH) 患急性冠状动脉综合征 (ACS) 的风险更大。通过 HIV 血清状态进行 ACS 管理的实践模式尚不清楚。我们检查了 PLWH 中 ACS 的表现和管理。 设计: 回顾性病例对照研究。 方法: 我们纳入了 86 例 PLWH 和 263 例性别匹配和种族匹配的 HIV 阴性对照,2004年和 2013 例 ACS 住院。我们进行了多变量条件 logistic 回归,以确定 HIV 血清状态与 ACS 类型和管理之间的相关性。 结果: 两组主要是黑人种族和男性。PLWH 显著年轻 (53 vs.60 岁),更容易吸烟 (48 vs.31%)。在 PLWH 中,30% 的 CD4 细胞计数小于 200 个/μ l,58% 的 HIV RNA 检测不到。与对照组相比,PLWH 有更多的单支血管病变和更高的中位 Gensini 评分 (32 vs.4.25)。HIV 血清状态与 ST 段抬高型心肌梗死 (STEMI) 呈正相关 [校正比值比 (aOR) (95% 置信区间 (CI)): 5.05 (1.82-14.02)], 和 ACS 后任何血运重建手术 [aOR (95% CI): 2.90 (1.01-8.39)],与非 STEMI 负相关 [aOR (95% CI): 0.33 (0.14-0.79)] 演示文稿。行支架置入术的 PLWH 与对照组相比,裸金属支架置入的可能性更高 [70 vs.15%,aOR (95% CI): 5.94 (1.33-26.55)]。在 PLWH 中,ACS 特征与 CD4 细胞计数、 HIV RNA 或抗逆转录病毒治疗无显著相关性。 结论: PLWH 住院的 ACS 患者更可能有严重的单支血管病变,表现为 STEMI 而不是非 STEMI,并进行血运重建。与匹配的 HIV 阴性对照相比,放置药物洗脱支架的可能性较小,提示冠状动脉斑块形态和/或分布与 HIV 感染不同,值得进一步研究。

METHODS:BACKGROUND: Glycoprotein IIb/IIIa inhibitors (GPIs) in combination with clopidogrel improve clinical outcome in ST-elevation myocardial infarction (STEMI); however, finding a balance that minimizes both thrombotic and bleeding risk remains fundamental. The efficacy and safety of GPI in addition to ticagrelor, a more potent P2Y12-inhibitor, have not been fully investigated. METHODS: 1,630 STEMI patients who underwent primary percutaneous coronary intervention (PCI) were analyzed in this subanalysis of the ATLANTIC trial. Patients were divided in three groups: no GPI, GPI administration routinely before primary PCI, and GPI administration in bailout situations. The primary efficacy outcome was a composite of death, myocardial infarction, urgent target revascularization, and definite stent thrombosis at 30 days. The safety outcome was non-coronary artery bypass graft (CABG)-related PLATO major bleeding at 30 days. RESULTS: Compared with no GPI (n = 930), routine GPI (n = 525) or bailout GPI (n = 175) was not associated with an improved primary efficacy outcome (4.2% no GPI vs. 4.0% routine GPI vs. 6.9% bailout GPI; p = 0.58). After multivariate analysis, the use of GPI in bailout situations was associated with a higher incidence of non-CABG-related bleeding compared with no GPI (odds ratio [OR] 2.96, 95% confidence interval [CI] 1.32-6.64; p = 0.03). However, routine GPI use compared with no GPI was not associated with a significant increase in bleeding (OR 1.78, 95% CI 0.88-3.61; p = 0.92). CONCLUSION: Use of GPIs in addition to ticagrelor in STEMI patients was not associated with an improvement in 30-day ischemic outcome. A significant increase in 30-day non-CABG-related PLATO major bleeding was seen in patients who received GPIs in a bailout situation.

METHODS:OBJECTIVES:There are limited data on bivalirudin monotherapy in patients with non-ST-segment elevation acute coronary syndromes (NSTE-ACS) with positive biomarkers of myocardial necrosis (troponin and/or creatine kinase-myocardial band isoenzyme). We sought to evaluate the safety and efficacy of bivalirudin monotherapy in patients with positive biomarkers from the Acute Catheterization and Urgent Intervention Triage Strategy (ACUITY) trial. PATIENTS AND METHODS:We compared the net adverse clinical events [composite ischemia - (death, myocardial infarction, or unplanned ischemic revascularization) - or noncoronary artery bypass graft surgery (CABG)-related major bleeding] among patients with biomarker-positive NSTE-ACS in the ACUITY trial overall and by antithrombotic strategy. RESULTS:Among 13 819 patients with NSTE-ACS enrolled in ACUITY, 4728 patients presented with positive biomarkers and underwent an early invasive strategy. Of those, 1547 were randomized to heparin plus a glycoprotein IIb/IIIa inhibitor (GPI), 1555 to bivalirudin plus GPI, and 1626 to bivalirudin monotherapy. Compared with biomarker-negative patients, biomarker-positive patients had higher 30-day rates of net adverse clinical events (14.0 vs. 12.4%; P = 0.04), all-cause death (1.3 vs. 0.5%; P = 0.001), cardiac death (1.1 vs. 0.5%; P = 0.005), and non-CABG-related major bleeding (6.5 vs. 5.2%, P = 0.03). At 30 days, bivalirudin monotherapy was associated with significantly less non-CABG-related major bleeding (bivalirudin monotherapy 4.1% vs. bivalirudin plus GPI 8.4% vs. heparin plus GPI 7.1%) with comparable rates of composite ischemia (bivalirudin monotherapy 9.2% vs. bivalirudin plus GPI 9.9% vs. heparin plus GPI 8.4%). In a multivariable model, bivalirudin monotherapy was associated with a significant reduction in non-CABG-related major bleeding but was not associated with an increased risk of death, myocardial infarction, unplanned revascularization or stent thrombosis. CONCLUSION:Compared with heparin plus GPI or bivalirudin plus GPI, bivalirudin monotherapy provides similar protection from ischemic events with less major bleeding at 30 days among patients with NSTE-ACS and positive biomarkers.

METHODS:Atrial fibrillation (AF) and concomitant coronary artery disease (CAD) create a therapeutic dilemma as the risk of bleeding with triple antithrombotic therapy (TATT) must be balanced against the risk of ischemic events with double antithrombotic therapy (DATT). The aim of this meta-analysis is to compare the efficacy and safety of DATT versus TATT in AF and CAD. MEDLINE, Cochrane, and ClinicalTrials.gov databases were searched for relevant articles published from inception to May 1, 2019. Studies comparing the safety and efficacy of DATT versus TATT in patients with AF and CAD were included. Among 9 studies, where 6,104 patients received DATT and 7,333 patients received TATT, there was no statistically significant difference in the outcomes of mortality, nonfatal myocardial infarction, stent thrombosis, and stroke. There was a lower rate of major bleeding in DATT (risk ratio [RR] 0.64 [95% confidence interval [CI] 0.54 to 0.75]; p <0.001). There was no significant difference in stent thrombosis (RR 1.52 [95% CI 0.97 to 2.38]; p = 0.07). However, subgroup analysis of trials with direct oral anticoagulant use demonstrated a borderline higher rate of stent thrombosis in DATT (RR 1.66 [95% CI 1.01 to 2.73]; p = 0.05). In conclusion, DATT showed no difference in the outcomes of mortality, stroke, nonfatal myocardial infarction, and stent thrombosis compared with TATT. DATT demonstrated a lower rate of major bleeding. DATT demonstrated a borderline higher rate of stent thrombosis in the subgroup analysis of trials with direct oral anticoagulant which needs to be evaluated in further studies.
