Viagra for heart attacks

 Theres been talk in the press recently of using Viagra to treat a heart attack or some heart conditions. 
 I strongly advise anyone with a heart condition reading that not to try it without consulting a doctor FIRST!  The reason is having read the paper (the medical paper not the daily mail) theres a number of factors that need to be addressed, and some heart conditions are made much worse by the drug, it also affects several other conditions that someone with a heart problem may well suffer too.
