Meds for the heart - Is that really helping or making you die in other ways?

This is an open discussion regarding wether meds are good or bad, in which I'll speak about my private and unique problem:

As time goes by, I thought that I'll cut the meds off by doctors' advice, but those are not coming, instead they want to add another type. 

Yeah I know that I should consult with a doctor, but already did, and when you read between the lines you realise one thing - this is not life or death, this is to keep you healthy, but there are nice probabilities that it is not necessarily helpful. And of course, those meds are serious. 

So serious that I ask myself - maybe I'm "saving" my heart from another heart incident, but killing my liver, kidneys and who knows what else.

The more I read and as time goes by and us simple citizens getting more suspicious, I don't even know that I'm doing the right thing here. Yeah, that is the western way and the "sure" way. 

But I have many (hopefully) years of taking those meds, as I was told it's for life in order to prevent another heart incident (though I didn't have a typical heart attack, something unusual which should not come back, but because it already happened, I should be cautious and take the F meds). I take 4 different meds - blood thinners, beta blockers, and statins. 

I really don't know wether I'm being fooled by the system (and don't say they don't care about 1 case, every case matters because when you sum all cases - you get a lot of money).

Maybe they are such good robots that say what they are told to say?

I really don't know, but with this new era of information, I'm wondering. Worrying and wondering. 

I take a bunch of pills now the worse for me is Plavix I get cut and bleed as if my carta artery was severed and any little thing I scrape against I bruise as if rocked by Tyson, but I was told it was needed for my body trying to clot the stints in my heart.

I was given a two year window till a new vessel wall built over the exposed metal stint. I take them for I see the benefits and the short term risks minimal vs not taking them and ending up with bypass or worse invasive procedure....
