Abstract

AIM We assessed the association between obstructive sleep apnea (OSA) and left ventricular hypertrophy (LVH) subtypes (i.e., concentric and eccentric LVH) trough a meta-analysis of echocardiographic studies. DESIGN The PubMed, OVID-MEDLINE, and Cochrane library databases were systematically analyzed to search full papers published from 1st January 2000 to 31st August 2019. Studies were detected by using the following terms: “obstructive sleep apnea”, “sleep disordered breathing”, “left ventricular mass”, “left ventricular geometry”, “left ventricular hypertrophy”, “echocardiography”. RESULTS Meta-analysis included 1,760 patients with OSA and 1,284 non-OSA controls from 9 studies. The prevalence rates of concentric and eccentric LVH in the pooled OSA population were 24.0% (confidence interval [CI] 16.0-33.0%) and 16.0% (CI 12.0-23.0%), respectively. Meta-analysis of six studies comparing the prevalence of LVH subtypes in participants with OSA and controls showed that OSA was associated with an increased risk of both concentric (odds ratio [OR] = 1.62, CI: 1.27-2.07, P < 0.0001) and eccentric (OR = 1.34, CI: 1.07-1.67, P < 0.009) LVH, respectively. CONCLUSIONS Our findings suggest that in the OSA setting concentric LVH is more frequent than eccentric LVH. From a practical perspective, in consideration of the particularly adverse prognostic significance of concentric LVH, a comprehensive echocardiographic evaluation targeting LVH subtypes could improve cardiovascular risk stratification in patients with OSA.
