A diagnosis of left ventricular hypertrophy on ECG is associated with a high cardiovascular risk: findings from a 40- to 69-year-old cohort in general practice.

Abstract

Left ventricular hypertrophy (LVH) is an independent cardiovascular (CV) risk factor in both sexes. We studied if a diagnosis of LVH on electrocardiogram (ECG) was associated with a 'high CV risk condition' among 40- to 69-year-old individuals cared for by GPs. We studied 4250 individuals, 5.4% of whom had LVH. Cross-sectional frequencies, and age- and gender-adjusted statistical differences have been calculated. All the study variables were significantly worse for 'LVH' than 'non-LVH' individuals (except smoking). The 'LVH' had both a mean '5-year CV risk' significantly greater than 'non-LVH' individuals (27.0% versus 8.6%), and a significantly higher prevalence of a '5-year CV risk >15%' (89% versus 15%). A diagnosis of LVH on ECG among the adult individuals of an opportunistic cohort from general practice was associated with a 6-fold greater prevalence of a 'high CV risk condition'.
