Hello, I have a friend who is 77 years old, CEO of a mid-sized international accounting firm, Caucasian, male, with extensive (pitting) edema of lower extremities and is prescribed three diuretics (loop, thiazide, and pril). He is in located in Manila, I suspect right heart failure, and convinced him to come to US (Stanford Med Ctr) for a workup next month. Any interim thoughts?
