Results of native T1 and T2 Mapping:
Using the 2SD above the mean T1 (1284.4 ms) and T2 (49.8 ms) values of
the healthy controls as a cut-off, raised T1 was reported in 16 (53.3%)
patients and raised T2 in 12 (40%) patients. Myocardial T1 (1284+ 43.8 ms vs 1147.6 + 68.4 ms; P<0.0001) and T2
values (50.8+ 16.7 ms vs 42.6+ 3.6 ms; P=0.04) were
significantly higher among post COVID-19 recovered subjects as compared
to healthy controls (Table 2). Additionally, subjects with abnormal CMR
findings had significantly higher myocardial T1 (1301.04+ 42.19 vs
1264.62+ 38.41; P=0.022) and T2 values (55.62+ 21.85 ms vs
45.25+ 3.02 ms; P=0.004) as compared to those with normal CMR
findings (Table 3).
