RESULTS: Resulted abnormal values of serum Biomarkers,echocardiographic and Doppler indices,PFTs,ABGs and Blood tests presented significant correlations as follows: CRP with A) D-dimers B) PCO2 C) NT-ProBNP D) EF E) LVID. Furthermore, A) D-dimers with A1) RVSP,correlated to LAD and LVID, A2) RVSP correlated with P(A-a)O2 and -FVC and -TLC, A3) PCO2. B) PCO2 with NT-ProBNP, FEV1 and Na, correlated with left ventricular E-Wave . C) NT-ProBNP with EF, PCO2 and C1) Tr-I, C2) ASH, C3) Hb, C4) Urea and Creatinine, C5) Pleural NT-ProBNP. However, C1) Tr-I correlated with left ventricular E/A ratio, MMP-2, EPO, - FVC and -TLC, - Na and Creatinine. C2) ASH with EF, Urea and Creatinine. C3) Hb with Pleural NT-ProBNP, TLC and PCT,correlated with MMP-2, Tr-I, EPO and PCO2. D) EF with FVC and Tr-I. E) LVID with LAD, RVSP, RVID, Creatinine and Urea.
