Guideline-directed medical therapy (GDMT) has been shown to improve outcomes for people with cardiovascular disease (CVD). Our goal was to assess racial and socioeconomic differences in GDMT use among a diverse population.
We examined the cross-sectional association of race and poverty status with GDMT among 441 participants with CVD in a longitudinal cohort of urban-dwelling Black and White adults in Baltimore City, Maryland, using multivariable logistic regression. CVD status and GDMT were self-reported.
The participants' mean age was 60.5 (SD 8.5) years, with 61.7% women, 64.4% Black, and 46.9% living below poverty. Of the 126 participants with coronary artery disease (CAD), 37.3%, 54.8%, and 62.7% were on aspirin, antiplatelets, and statins, respectively. Black participants with CAD were less likely to be on aspirin, OR 0.29 (95% CI 0.13-0.67), and on combination GDMT (antiplatelet and statin), OR 0.36 (0.16-0.78) compared to Whites. There were no differences by poverty status in GDMT for CAD. Fully, 222 participants reported atrial fibrillation (AF), but only 10.5% were on anticoagulation with no significant difference by race or poverty status. The use of GDMT for heart failure and stroke was also low overall, but there were no differences by race or poverty status.
Among an urban-dwelling population of adults, the use of secondary prevention of CVD was low, with lower aspirin and combination GDMT for Black participants with CAD. Efforts to improve GDMT use at the patient and provider levels may be needed to improve morbidity and mortality and reduce disparities in CVD.
有研究表明,指南指导的医学治疗(GDMT)可改善心血管疾病(CVD)患者的预后。我们的目标是评估不同人群中 GDMT 使用的种族和社会经济差异。
我们使用多变量逻辑回归,分析了马里兰州巴尔的摩市居住的黑人和白人成年人的纵向队列中,441 名 CVD 患者的种族和贫困状况与 GDMT 之间的横断面关联。CVD 状况和 GDMT 均为自我报告。
参与者的平均年龄为 60.5(8.5)岁,其中 61.7%为女性,64.4%为黑人,46.9%生活在贫困线以下。在 126 名患有冠心病(CAD)的患者中,分别有 37.3%、54.8%和 62.7%服用阿司匹林、抗血小板药物和他汀类药物。与白人相比,患有 CAD 的黑人患者服用阿司匹林的可能性更低,OR 为 0.29(95%CI 0.13-0.67),服用联合 GDMT(抗血小板和他汀类药物)的可能性也更低,OR 为 0.36(0.16-0.78)。在 CAD 患者中,根据贫困状况,GDMT 无差异。共有 222 名参与者报告患有心房颤动(AF),但仅 10.5%服用抗凝剂,种族或贫困状况无显著差异。心力衰竭和中风的 GDMT 总体使用率也较低,但种族或贫困状况无差异。
在城市居住的成年人中,CVD 二级预防的使用率较低,黑人 CAD 患者阿司匹林和联合 GDMT 的使用率较低。可能需要在患者和医务人员层面上努力提高 GDMT 的使用率,以改善发病率和死亡率,并减少 CVD 方面的差异。
