In the univariate regression analysis, the following parameters were associated with the numbers of persisting symptoms defining both post-acute COVID-19 syndrome and the presence of DD, along with average E/e’ values: age (p < 0.001), BMI (p < 0.001), the number of MS factors (p < 0.001), CRP levels (p < 0.001), pulmonary injury on CCT (p < 0.001), weeks since COVID-19 infection (p < 0.001), PCFS (p < 0.001), SBP values (p < 0,0001), DBP values (p < 0.0001), and LVMI (p < 0.0001). Here, CRP is linked to myeloid sarcoma.
