Ahmad MI, et al. - Given that left ventricular hypertrophy (LVH) and left atrial abnormality (LAA) represent common correlated complications of hypertension, researchers investigated the prevalence of the coexistence of electrocardiographic markers of LAA (ECG-LAA) and ECG-LVH, and focused on the influence of their coexistence on their prognostic value. From the Third National Health and Nutrition Examination Survey, a total of 4,077 participants (61.2 ± 13.0 years; 51.2% women; 48.6% white) with hypertension were identified and included in this analysis. Cornell voltage criteria were used to define ECG-LVH. Deep terminal negativity of P wave in V1 > 100 µV defined ECG-LAA. The reported baseline prevalence of ECG-LVH was 3.6%; ECG-LAA was 2.7% and the concomitant presence of both was 0.34%. ECG-LAA and ECG-LVH were identified as independent markers of poor outcomes in participants with hypertension, and a higher risk was reported in relation to their concomitant presence vs the presence of either marker alone.
