摘要

Left ventricular hypertrophy (LVH) is one of the strongest predictors of cardiovascular disease (CVD) and mortality; yet the means to diagnose LVH in resource-constrained settings remain limited. The objectives of this study were to determine LVH prevalence by transthoracic echocardiography (TTE) in a high-risk group, and compare TTE vs. electrocardiography (ECG-LVH) for LVH detection. We analyzed enrollment data from the Haiti cardiovascular disease cohort study on adults (≥ 18 years, n = 3,005) in Port-au-Prince between 2019 and 2021. All participants underwent questionnaires, vital signs, physical exams, and 12-lead ECGs. TTEs were acquired on those with hypertension or exhibiting CVD symptoms (n = 1040, 34.7%). TTE-LVH was defined according to the American Society of Echocardiography guidelines and ECG-LVH by Sokolow-Lyon, Cornell, and Limb-Lead Voltage criteria. The prevalence of TTE-LVH was 39.0% (95% CI 36.6–41.5%) and associated with older age. Only 26% of those with TTE-LVH and elevated blood pressure were on antihypertensives. Prevalence of ECG-LVH ranged from 1.9 to 5.0%, and compared to TTE-LVH had low agreement (κ < 0.20), low sensitivity (< 10%) and high specificity (> 90%). These findings indicate a high prevalence of TTE-LVH among high-risk Haitian adults, and poor detection using ECGs compared to TTEs. For those with TTE-LVH, treatment with antihypertensives may reduce the risk of adverse CVD outcomes.
