Electrocardiographic index in aortic root enlargements and ventricular hypertrophy with Phi-based chest-wall thickness derived measure

Introduction: In addition to left ventricular hypertrophy (LVH), dilated aortic root (DAo) is a risk factor for cardiovascular events. There is a ack of a practical index that considers both scenarios. Objective: To assess an electrocardiographic index in DAo and LVH considering echocardiographic guidelines and those values stemming from the chest wall thickness (CT). Methodology: The population was 631 patients, 236 hypertensives (HT) and 395 non-hypertensives (NHT), the diameter of the aortic root was based on the Phi number and a derived formula CT x 1.33 = Ao, using a cut-off >15%.
