ABSTRACT
OBJECTIVE:
Left ventricular hypertrophy (LVH) is a marker of cardiovascular risk. However, the progression of the risk as a function of the course of the LVH has only been the subject of few studies.METHODS:
We report the consequences of the evolution of the left ventricular mass (LVM) in a cohort of hypertensive patients whose LVM was measured before any antihypertensive treatment.RESULTS:
We followed up for an average of 12 years, 763 hypertensives with LVM measurement by echocardiography on inclusion. In this population, 117 cardiovascular complications occurred and the initial LVM appeared to be the most powerful marker of risk. A cutoff of 51 g/m(2.7) for the LVM index (LVMI) offered the best compromise of sensitivity and specificity in the prediction of complications. A second determination of LVM was carried out in 436 patients on average 5 years after inclusion. In this sub-group, 82 complications were recorded after an average interval of 13 years. The 51 g/m(2.7) value of LVMI over the follow-up offered the same sensitivity (74%) and specificity (52%) in the prediction of complications. The progression of the LVM was related to the occurrence of complications independently of the basal value and other risk factors.CONCLUSIONS:
We confirm LVMI as a powerful risk factor in hypertension with a cutoff of 51 g/m(2.7), which offers the same sensitivity and specificity whether the LVM was determined before or during treatment. The progression of LVM, on average 5 years after the initial measurement had a prognostic value independent of the initial determination.
