Grade 1 Diastolic Dysfunction Is Not "Normal for Your Age"
Grade 1 diastolic dysfunction shows up on echocardiograms all the time, and it's routinely brushed off. Your heart's relaxation phase is slightly stiff, but your filling pressures look fine, and you probably feel nothing. The problem: community data link this silent finding to higher all-cause and cardiovascular mortality over 15 to 20 years, even when it appears completely isolated with no other echo abnormalities. It also predicts future heart failure, stroke, and end-stage renal disease, particularly when it shows up between ages 40 and 55. So if someone tells you this is just what happens with aging and not worth worrying about, that's incomplete at best. Grade 1 diastolic dysfunction is the earliest detectable stage of abnormal left-ventricular filling, a point where the trajectory can still be changed.
