To test the effect of cMyBP-C phosphorylation status on the MI-HF rat model, we collected protein samples from the left ventricular (LV) infarct zone of MI rats and a comparable area from sham animals at five different time points post-MI surgery: day 1, day 3, week 1, week 4 and week 8. This evidence concerns the gene MYBPC3 and myocardial infarction.
