Lets not forget that Viagra orignally started life as a possible blood pressure medication!!..
In essence a heart "attack" is where a bit of muck carried around in the bloodstarem gets lodged in the heart muscele so it can't work as well as it might owing to lack of blood supply. So it protestes with pain and it gived off an enyzeme called Troponin which is a very good marker to know if you have suffered a bout.
Assuming you get past that point stents are uised to prop open blocked or semi blocked artieries and then hypertension treatment candasartern and Amlodpine etc then blood thinners and an anticoagulent and thats more or less that apart from nitrates are sometimes admisnered and thats wot cauuses the issue with Viagra and the like..
In a nutshell! In fact quite a few people mainly women can have a heart attack and not reliase it they don't always present with someone clutching their chest saying call me an ambulance!!!
Etc...
High Blood Pressure and Angina Pectoris was what viagra was intended to treat until the people in the trial noticed the unintended benefits
If you check BNF you can see the indications and contra indications relating to Viagra being prescribed
The main concern is hypotension caused by taking medications that lower blood pressure at the same time.
That doesn’t mean a person with previous cardiac problems won’t be prescribed it, but I would suspect most online pharmacy’s would not prescribe it, your own GP or Consultant will likely have a different opinion based on the fact they can examine you and have access to your full medical history
Many people don’t know the different between angina and an MI.
Often people with angina think they are having a “Heart Attack” when they aren’t
MI is diagnosed initially by 12 lead ECG then confirmed with Trops.
If you are diagnosed pre hospital with a STEMI you may be taken directly to a Cath Lab rather than A&E, since the early 2000’s in London where the early trials of bypassing A&E took place and you would’ve taken directly to Bonner Road
The only medical episode I have seen after Viagra usage was a stroke not an MI or hypotension
