Clinical Vignettes
Case 1
A 48-year-old diabetic, hypertensive man with unlimited exercise tolerance was referred to echocardiography to evaluate atypical chest pain. His blood pressure was 160/100 mm Hg on valsartan and hydrochlorothiazide. He was mildly overweight with a normal exam. The LV ejection fraction (LVEF) was normal with normal valvular function. On echocardiographic exam, LV geometry was normal (Figure 5-13A):
Case 2
A 60-year-old man with hypertension, myelofibrosis, and multiple falls underwent echocardiography during evaluation of presyncope. His blood pressure was 131/77 mm Hg on amlodipine and captopril. He was normal weight with a normal exam. His hemoglobin was 8.0 gm/dL. The LVEF was normal with normal valvular function (Figure 5-14A). On echocardiographic exam:
