<qa>  What is the most prevalent complication after MI?A brief description of the issue and the original value of the subject: Epidemiological studies show a clear increase ininfarct-related complications due to increased survival after MI and aging population. Heart failure is the most prevalent complication after MI, which has reached epidemic proportions in western societies. For the period between 2010 and 2030,according to projections made in developed countries, about 10 increment in all cardiovascular disease is being predictedhowever increment in heart failure HF would be such a dramatic figure which is about 25. HF is an increasing burden tosociety and healthcare systems, since its prevalence and incidence is dramatically increasing. There has not been aprospective study that assesses the exact cellular and geometric course after MI in human. This study will allow us tounderstand the behavior of cells involved in cardiac repair after MI. In addition, it will show us the exact functional andgeometric course after MI. Finally, the current study will also provide novel diagnostic and therapeutic targets via genomic andproteomic studies. All together, we envision to find new efficient ways to identifytreat patients at risk to develop HF after MI.
