Had a heart attack in 2007. A 100% blocked artery, but no indication of clogged arteries or need for surgery. They did place a stent. I was 58 at the time and had been experiencing what I later found to be unstable angina 2 days prior to the MI. Have read that some heart attacks are the result of vasoconstriction, (sp?) and wonder if my having Raynaud s disease is related? I always have a lower than normal body temp too, usually around 96.8, but gets as low as 94 when ill. For the past year I ve been taking a vaso dilator, isosorbide, and have only had to take my nitro once in that time. Guess my actual question is how does being cold, Raynaud s, and heart attack relate?

Summarized question: Does Raynaud s disease cause heart attacks?
