Diastolic dysfunct: achieving max heart rate(HR) important to assess for issues of poor blood flow/blockages in heart arteries. Not as important to assess dyastolic dysfunction (heart does not relax fully in between beats). Pulmonary HTN also does not need max HR to assess. Any risks for obstructive sleep apnea (common cause of pulm HTN)? Stay in touch with your cards. Might discuss sleep study. Hope this helps.

Predictor of disease: It seems that you may be referring to two different things-an exercise stress test and a heart catheterization are two different things.In an exercise stress test,if the heart rate does not get up to 85% of its maximal predicted value, this is known as chronotropic incompetence and can be a predictor of coronary heart disease and left ventricular dysfunction.Cath is diagnostic of specific disease

Result of heart echo slightly hypertrophied in diastole with some diastolic dysfunction i don't understand im no doctor, help? I'm worried !
The results of my Echocardiogram was: Reduced LV systolic function with LVEF 40%. Mild diastolic dysfunction. Normal RV systolic function. No significant valvular heart disease. What exactly does this mean? How is it treated?
I had heart cath done -the results -23mmHG peak to peak gradient across the aortic valve on pullback and the LVEDP is 17mmHG - the LV systolic and diastolic pressures are elevated. I also have POTS and NCS. Does this test suggest valve replacement?
Chest pain. Ekg, d-dimer, asa, chest xray, ESR "normal". Echo says "restrictive pattern lv diastolic fill". Anxious re risk of cad/athero & heart attack. ?
