I do have some experience with this problem. Mild heart attack in
2007 (most probably caused by spasm, arteries were in pristine condition), followed by insertion of 6 cypher stents to support the one artery: 1 x 18mm, 1 x 23mm, 2 x 30mm and 2 x 33mm. Three and a half years later in 2010, naturally I was no longer taking dual anti-platelet therapy that long post-stenting - just the 81mg aspirin. But, had a very severe stent thrombosis and a serious MI. I'm very lucky to be here today.
