Preventable cardiovascular disease (CVD) risk factors are responsible for the majority of CVD-related deaths, and are increasingly recognized as a cause of morbidity and mortality for HIV-infected persons taking antiretroviral therapy (ART). Simplified tools such as the American Heart Association's ideal cardiovascular health (iCVH) construct may identify and prognosticate CVD risk in resource-limited settings. No studies have evaluated iCVH metrics in sub-Saharan Africa or among HIV-infected adults. Thus, the central aim of this study was to compare levels of iCVH metrics and their correlations with carotid atherosclerosis for HIV-infected adults versus uninfected controls in a well-phenotyped Ugandan cohort. We analyzed the prevalence of iCVH metrics in a mixed cohort of HIV-infected persons on stable ART and uninfected, population-based comparators in Mbarara, Uganda. We also assessed the validity of iCVH by correlating iCVH values with common carotid intima media thickness (CCIMT). HIV-infected persons had a mean of 4.9 (SD 1.1) iCVH metrics at ideal levels versus 4.3 (SD 1.2) for uninfected controls (p = .002). This difference was largely driven by differences in blood pressure, blood glucose, and diet. In multivariable-adjusted linear regression models, each additional iCVH metric at an ideal level was associated with a significant 0.024 mm decrease in CCIMT (p < .001).HIV-infected persons on ART in rural Uganda had more iCVH metrics at ideal levels than uninfected persons. The difference appeared driven by factors that are putatively influenced by access to routine medical care. Composite scores of iCVH metrics were associated with subclinical atherosclerosis and more predictive of atherosclerosis for uninfected persons.
可预防的心血管疾病(CVD)风险因素是大多数与CVD相关死亡的原因,并且越来越被认为是接受抗逆转录病毒疗法(ART)的HIV感染者发病和死亡的原因。诸如美国心脏协会的理想心血管健康(iCVH)构建等简化工具可以在资源有限的环境中识别和预测CVD风险。尚无研究评估撒哈拉以南非洲或HIV感染成年人中的iCVH指标。因此,本研究的主要目的是比较在一个特征明确的乌干达队列中,HIV感染成年人与未感染对照的iCVH指标水平及其与颈动脉粥样硬化的相关性。我们分析了乌干达姆巴拉拉一个混合队列中接受稳定ART的HIV感染者和基于人群的未感染对照者的iCVH指标患病率。我们还通过将iCVH值与颈总动脉内膜中层厚度(CCIMT)相关联来评估iCVH的有效性。HIV感染者理想水平的iCVH指标平均有4.9个(标准差1.1),而未感染对照者为4.3个(标准差1.2)(p = 0.002)。这种差异主要由血压、血糖和饮食差异驱动。在多变量调整线性回归模型中,理想水平每增加一个iCVH指标,CCIMT就显著降低0.024毫米(p < 0.001)。乌干达农村地区接受ART的HIV感染者理想水平的iCVH指标比未感染者更多。这种差异似乎是由可能受获得常规医疗服务影响的因素驱动的。iCVH指标的综合评分与亚临床动脉粥样硬化相关,并且对未感染者的动脉粥样硬化预测性更强。
