hi
as per your query
bee sting has nothing to do with congestive haret ailure
there are a numbe of causes of chf, in most of the people it takes many year for the ef to lower from 60% to 35% but there are diseases like cardiomyopathies
avandia (rosiglitatzone) has been banned in the market because it has serious side effects like causing a
heart attack and precipitating chf...this rapid detoriation of your father lv functions can be because of rosiglitazone
if there is no findings of any particular cardiac disease in his echo,it can be a chf caused by rosiglitazone
if echo reports of your father showed some regional wall motion abnormality then another possiblity is that your father got a silent heart attack(as a side effect of rosiglitazone) (in diabetic due to neuropathy many times
chest pain is not there),so as the heart attack passe un noticed his
ejection fraction decreasedby time
till the time you see a specialist
tab lasilactone 50 mg once daily
tab carca(carvedilol) 3.125mg twice daily
tab cardace (
ramipril) 2.5 mg once daily
tab flavidon mr 35mg(trimetazidine increases the ejection fraction ) should be given
