P<0.05 versus control. AS Aortic stenosis; CRF Chronic renal failure; DM Diabetes mellitus; EF Ejection fraction; HBP High blood pressure; NA Data not available; NS Not statititically significant. FS_m and FS_l are generally reduced despite relatively preserved FS_en and EFs. FS_en are greater than FS_m and FS_ep
