A model for comparison of left ventricular mass and systolic blood pressure as risk factors for stroke.
Electrocardiographic left ventricular hypertrophy (increased left ventricular mass) is a known risk predictor of stroke independent of blood pressure level. However, electrocardiography is an insensitive index of such hypertrophy. To assess the potential risk associated with increased left ventricular mass via continuous measurement (as is becoming available with echocardiography), published longitudinal data from the Framingham study were used to estimate risk of stroke associated with various levels of increased left ventricular mass. This model predicts that left ventricular mass is at least as powerful as, if not more powerful than, systolic blood pressure levels for predicting risk of stroke.
