Prevalence and covariates of electrocardiographic left ventricular hypertrophy in the Hypertension in the Very Elderly Trial

Abstract

Prevalence and covariates of electrocardiographic LVH varied by sex, race, and ECG criterion. CP-LVH may prove to be the most useful measure of LVH in this study owing to its close relationship to SBP, at least in women, and independence from BMI.

Left ventricular hypertrophy is a predictor of cardiovascular events in elderly hypertensive patients

“…In the studies of people aged at least 75 years, the prevalence of anatomical, x-ray LVH or ECHO LVH is very high at 44%-87% [ 12,13] and the prevalence of ECG LVH 2-25% [12][13][14][15], depending on the age-subgroup, LVH criterion and hypertensive status used. Despite this, the information on the risks associated with LVH in very elderly hypertensive subjects is scarce [10,12] and to our knowledge, this information is missing in hypertensive subjects aged 80 years and more.…”

“…The relationship between the endpoints, the presence of baseline SL-, CV-, and CP-LVH and other baseline variables (age, gender SBP, DBP, heart rate, BMI, serum cholesterol, hemoglobin, creatinine and uric acid concentration, history of CVD, diabetes, antihypertensive drug treatment at baseline, smoking and alcohol use and randomization to intervention/placebo group) was determined using a Cox proportional hazard regression model. The variables selected have been associated with the presence of ECG LVH in previous studies[15,22,23]. Information was missing for serum uric acid in 17 participants, cholesterol in six, hemoglobin level in four, heart rate measurements in three and BMI in one participant.…”
