Furthermore, in a study involving 37 patients with ST-elevation myocardial infarction (STEMI), those assigned to an ET group exhibited increased numbers and migration capacity of circulating progenitor cells (CPCs), decreased brain natriuretic peptide (BNP) levels, and elevated maximum oxygen consumption (VO2 max) after regular ET [101]. This evidence concerns the gene NPPB and ST Elevation Myocardial Infarction.
