My mother (60 yrs age) has been suffering from vertigo like symptoms and excessive tiredness after physical activity (brisk walking). I got a heart checkup done. The 2D Echocardiography reports states as follows: IMPRESSION: ISGHEMIC HEART DISEASE Comments: RWMA AT REST LV SYSTOLIC DYSFUNCTION LVEF = 50% TYPE II DIASTOLIC DYSFUNCTION NO PERICARDIAL EFFUSION NO MR,NO TR NO CLOT/VEGETATION The doctor is insisting we go for an angiography. I would like a second opinion before going for it.
