Impact of Metabolic Syndrome and/or Diabetes Mellitus on Left Ventricular Mass and Remodeling in Patients With Aortic Stenosis Before and After Aortic Valve Replacement

In aortic stenosis (AS), metabolic syndrome (MetS), and diabetes mellitus (DM) are associated with more pronounced left ventricular (LV) hypertrophy and more concentric remodeling. We aimed to assess the impact of MetS and DM on LV mass, remodeling, and LV mass regression after aortic valve replacement (AVR) in patients with severe AS. We included 177 patients with severe AS and preserved LV ejection fraction (>50%). All patients underwent a complete echocardiogram before and 1 year after AVR. Forty-seven (27%) patients had MetS, 37 (21%) DM, and 93 (52%) neither MetS nor DM (No MetS-DM). Before AVR, indexed LV mass was higher in MetS and DM groups compared with No MetS-DM group (56.1 ± 14.2, 56.2 ± 18.2 vs 49.2 ± 14.1 g/m 2.7 , respectively; p
