We investigated the correlation between ECG LVH and mortality in a hypertensive Chinese population aged 80 years and older.Patients and methods: In this study, we included 284 Chinese participants older than 80 years. All included participants with hypertension (sitting systolic blood pressure [BP] 160 to 200 mmHg; sitting diastolic BP <110 mmHg) were ascertained at the baseline. ECG LVH was defined as a Sokolow-Lyon voltage calculated as the amplitude of SV1+ (max RV5 or RV6) greater than 3.5 mV. We categorized participants into two groups by the status of baseline ECG LVH. We used Cox regression models to calculate hazard ratio (HRs) for mortality due to ECG LVH, including cardiovascular mortality and all-cause mortality.Results: In this study, with a 28-month median follow-up, a total of 35 (12.3%) patients died; 21 of those died due to cardiovascular causes. Compared with participants without ECG LVH, there was an increased risk of cardiovascular mortality in participants with ECG LVH (adjusted HR 4.25 [95% confidence interval [CI], 1.50–12.06]) but ECG LVH did not predict all-cause mortality (adjusted HR 2.31 [95% CI, 0.93–5.72]).Conclusion: Our study shows that ECG LVH predicts the risk of cardiovascular mortality in an oldest-old hypertensive Chinese population.Keywords: left ventricular hypertrophy, mortality, oldest-old, hypertension, ChinaChen RBai KLu FZhao YPan YWang FZhang LDove Medical Pressarticleleft ventricular hypertrophymortalityoldest-oldhypertensionChinaGeriatricsRC952-954.6ENClinical Interventions in Aging, Vol Volume 14, Pp 1657-1662 (2019)
