Impact of Inflammatory and Hematological Factors to The Left Ventricule Function, Remodeling, and Clinical Outcomes after The First Myocardial Infarction

Abstract Background It is known that hematological and inflammatory factors can affect the prognosis of patients with AMI, but the interpretations are different. Material and methods The study included 182 patients with their first AMI age < 70 years. Inflammatory (CRP, Sedimentation and Leukocytes), hematological factors (Platelets, Iron, Hct) and coronary status were obtained at admission. Doppler echocardiography was performed two days after admission and after 6 months.The degree of heart failure was assessed by clinical examination. Results and conclusions Remodeling of LV, measured by LV volume increase and Sphericity index was closely related to Sedimentation level (P = 0.013; P = 0.028). Sedimenation was related to systolic function measured by LVEF (P = 0.011) and with diastolic dysfunction measured by E/e ratio (P < 0.001). A significant impact of CRP on LVEF (P = 0.028) and degree of diastolic dysfunction (P = 0.024) was estimated. Iron level had an effect on LVEF (P = 0.017), while E/e was negatively correlated with Iron (P = 0.005). The degree of heart failure was positively correlated with the level of Iron and Sedimentation. Sedimentation level of 22.5 cut off had a sensitivity of 75%, a specificity of 52% in predicting NYHA III and IV. Iron level of 8.1 has a sensitivity of 72.4%, specificity of 57.9% in predicting NYHA III and IV. There were no significant correlations between coronary status and inflammation parameters .Inflammatory hematological status of patients is associated with changes in the morphology and function of the LV after the first MI. The sedimentation level and CRP contribute to a better risk stratification for the severity of heart failure.
