Meanwhile, the mean T1 values of infarcted myocardium were higher in patients with high GSDMD concentrations (≧ 13 ng/L) both in the acute and chronic phase after infarction (1564 ± 79 ms vs. 1370 ± 50 ms, P = 0.01; 1660 ± 73 ms vs. 1335 ± 48 ms, P = 0.01) (Figure 3, Table 3). The gene discussed is GSDMD; the disease is infarction.
