Chen R, Bai K, Lu F, et al. - In a hypertensive Chinese population (n = 284) aged 80 years and older, researchers inquired about the correlation between electrocardiographic pattern of left ventricular hypertrophy (ECG LVH) and mortality. A Sokolow-Lyon voltage, calculated as the amplitude of SV1+ (max RV5 or RV6) greater than 3.5 mV, defined ECG LVH. Two groups of participants were defined based on the status of baseline ECG LVH. Participants were observed over a 28-month median follow-up. An increased risk of cardiovascular mortality was observed in participants with ECG LVH vs those without ECG LVH. All-cause mortality was not predicted by ECG LVH. Overall, the prediction of the risk of cardiovascular mortality in an oldest-old hypertensive Chinese population was enabled by ECG LVH.
