Prognostic effect of inappropriately high left ventricular mass in asymptomatic severe aortic stenosis

ObjectivesIn patients with aortic stenosis (AS) left ventricular (LV) myocardial growth may exceed individual needs to compensate LV haemodynamic load leading to inappropriately high LV mass (iLVM), a condition at high risk of adverse cardiovascular events. The prognostic impact of iLVM was determined in 218 patients with asymptomatic severe AS.MethodsiLVM was recognised when the measured LV mass exceeded 10% of the expected value predicted from height, sex and stroke work (prognostic cut-off assessed by a specific ROC analysis). For assessment of outcome, the endpoint was defined as death from all causes, aortic valve replacement or hospital admission for non-fatal myocardial infarction and/or congestive heart failure.ResultsAt the end of follow-up (22+13 months) complete clinical data were available for 209 participants (mean age 75+11 years). A clinical event occurred in 81 of 121 patients (67%) with iLVM and in 26 of 88 patients (30%) with appropriate LV mass (aLVM) (p
