Hello, so I have familial hyper cholesterol and had my first stent at 30 years old. I now have a total of 5 and I’m 42. My question is this…..I have had heart palpitations on and off for years now, usually I just take my nitroglycerin and it goes away. Will this always be an issue? Last night I felt a discomfort in my chest that I have felt many times in the past, it was followed by sweating all over. This has happened several times before as well, I took my nitroglycerin and it went away. Is this something I should be worried about, or just normal for someone with heart disease and 5 stents?
