title: Modification in serum concentrations of aminoterminal propeptide of type III procollagen in patients with previous transmural myocardial infarction.
abstract: The aim of our study was to evaluate the modification of serum concentration of aminoterminal propeptide of type III procollagen (PIIINP) in 70 patients with previous transmural myocardial infarction. In 38 patients (group 1 ) PIIINP levels increased at 6 and 12 months after infarction; in 32 patients (group 2) PIIINP increased at 6 months, returning to baseline at 12 months. At the same time we observed a significant left ventricular enlargement and worsening of the performance in group 1, whereas in group 2 an improvement was seen in left ventricular volumes and performance. In conclusion, rearrangement of collagen myocardial matrix plays an important role in left ventricular postinfarction modification. This process can be easily followed over time in a noninvasive manner by dosing serum PIIINP concentrations.
