  • Title: Left ventricular hypertrophy: a potent cardiovascular risk factor and its relationship to office and ambulatory blood pressure.
    Author: Mansoor GA, Massie BM.
    Journal: Blood Press Monit; 1999; 4 Suppl 1():S19-22. PubMed ID: 10822413.
    Abstract:
    Left ventricular hypertrophy (LVH) is an important cardiovascular risk factor. The presence of LVH carries risk independent of hypertension. LVH can be detected non-invasively using electrocardiography or echocardiography. Clinical studies have consistently shown that ambulatory blood pressure is a stronger correlate of left ventricular mass than office blood pressure. Furthermore, treatment-induced decreases in left ventricular mass index are also more tightly related to reductions in ambulatory blood pressure than reductions in office blood pressure. The primary intervention for subjects with hypertension and LVH is optimal blood pressure control. Several small studies now suggest that therapeutic changes resulting in regression of left ventricular mass also confer a reduction in cardiovascular risk. Therefore, LVH is a serious negative risk factor that is more closely related ambulatory rather than office blood pressure. Fortunately, current evidence suggests that optimal antihypertensive therapy resulting in regression of hypertrophy will reduce at least short-term cardiovascular events. Physicians need to be more aware of LVH as a cardiovascular risk factor.
