I am curious as to what percent of people who are stented after MI end up progressing to heart failure in the long term. anyone have any information on this?
There are some many variable to take into consideration that an estimate of what you're asking would be extremelity diffucult to make. For example, just to name a few of the progression from AMI to HF depends on:
1. Time between onset of AMI and PCI, obviously the longer the wait, the worse the outcome.
2. Vascular territory compromised: LAD occlusions tend to have worse outcomes since the anterior wall and septum are likely the most important walls for an adequate pump function.
3. Type of AMI, STEMI vs. NSTEMI, the former tends to cause transmural (full thickness) myocardial damage, whereas NSTEM, often times cause non-transmural infarcts, however that's not a rule. In any case, transmural infarctions do worse than non-transmural infacts.
4. Comorbidities: Diabetics and patients with severe renal dysfunction do worse than other patients.
5. And perhaps, the type of stent, baremetal vs. drug eluting stents, may also have some differences in outcomes.
