Reuters Health - 03/12/2020 - Differences in left atrial structure and pathophysiology between Black and white ischemic stroke patients may help explain racial disparities in stroke risk, a U.S. study suggests. Researchers examined data on 3,426 ischemic stroke patients who were participants in the Greater Cincinnati/Northern Kentucky Stroke study and had no history of atrial fibrillation or flutter. The mean left atrial diameter measurement was 3.65cm, with a smaller mean diameter for Black patients (3.58 cm) than for white patients (3.69 cm), based on an analysis of data for 2,391 participants. When researchers analyzed P-wave terminal force in ECG lead V1 (PTFV1) in a subset of 3,209 participants, they found the overall mean PTFV1 measurement was 3,434 mV*ms. Black race was associated with higher measurements (adjusted beta coefficient 1.45), with a mean in Black patients of 3,183 mV*ms versus 2,258 mV*ms in white patients, according to the report publishe...
