This study revealed a direct correlation between serum PIIINP levels, severity of cardiac fibrosis, and indicators of diastolic function after 1 year of STEMI with preserved LVEF. Patients with PIIINP levels exceeding 381.4ng/ml on the 12th day post-STEMI had an increased risk of cardiac fibrosis. Monitoring PIIINP levels during the inpatient period may help identify high-risk patients for cardiac fibrosis 1 year after STEMI with preserved LVEF.
The aim of the study were to evaluate the prognostic potential of serum level of N-terminal propeptide procollagen type III (PIIINP) and heart parameters for predicting heart cardiac fibrosis 1 year after ST-segment elevation myocardial infarction (STEMI) with preserved left ventricular ejection fraction (LVEF). 68 patients with STEMI and preserved LVEF with acute heart failure of the I-III degree according to the Killip classification were examined. Echocardiography was performed and PIIINP levels were measured on days 1 and 12, as well as 1 year after STEMI. A year after STEMI, was performed contrast magnetic resonance imaging and patients were assigned into four groups depending on the severity of cardiac fibrosis: cardiac fibrosis 0% (n=49, 57% of 86 patients); <= 5% (n=18, 20.9%); 6-15% (n=10, 11.6%); >= 16% (n=9, 10.5%). Direct correlations between the severity of cardiac fibrosis, PIIINP level and indicators of diastolic function were established. The risk of cardiac fibrosis increases at the level of PIIINP >= 381.4 ng / ml on the 12th day after STEMI with preserved LVEF (p=0.048). Thus, measuring the level of PIIINP in the inpatient period can allow timely identification of patients with a high risk of cardiac fibrosis 1 year after STEMI with preserved LVEF.
