79 year old father with diagnosis today at yearly check up at cardio specialist of 1. diastolic heart failure (chronic), 2. atrial fib, 3. Benign hypertension, 4. Hypercholesterolmia, 5. Cardiomyopathy, other primary, 6. Dyspnea, 7. Low blood pressure. Previous year official diagnosis was only atrial fib, dyspnea, slight hypertension, with possible CHF, little or no high cholesterol readings, not diabetic. Was told he had a heart murmur when young, never has eaten much salt, however drank up to a liter of diet soda daily up until six months ago, never smoked. Has always been overweight, current weight is 284, which is somewhat less than last year. Sleeps with breathing machine due to apnea, cannot walk 25 feet without shortness of breath. Occasionally has legs fall asleep, especially when driving. Over he past few weeks left hand has had tingling and sensation of falling asleep. Meds prescribed over the last year or so are amlodipine 10 mg 1xdaily, hydrochlorothiazide 25 mg 1x, lotensin 40 mg 1x, meloxicam 15 mg 1x, and pradaxa 75 mg 2x daily. Today they scheduled his annual 2Dwith CFD Echocardiogram for mid October. On the hour drive back from the appointment, his hand fell asleep again with the tingling sensation. The doctor seems unconcerned, but I feel that today s BP readings of 82/38 should be of concern. I had always thought that diastolic readings that low were dangerous, and also reflected low oxygen levels, although I can see why they need to be kept somewhat low for his condition. I am questioning the medication program as to whether it may be more than he needs. What critical symptoms do I need to watch for?
