Changes of cardiac troponin I and hypersensitive C‑reactive protein prior to and after treatment for evaluating the early therapeutic efficacy of acute myocardial infarction treatment

Abstract

The present study aimed to evaluate the utility of the extent of change (C) and change rate (Cr) of cardiac troponin I (cTnI) and hypersensitive C-reactive protein (hs-CRP) prior to and after treatment in evaluating the early therapeutic efficacy of acute myocardial infarction (AMI) treatment. A total of 145 patients with AMI who received regular MI treatment were enrolled in the present study. Patients were divided into the effective group and the ineffective group based on the early therapeutic efficacy. The values of two parameters, namely the serum levels of cTnI and hs-CRP, were collected prior to and after AMI treatment. Data were analyzed by using the t-test, Chi-squared test, logistic regression and receiver operating characteristic (ROC) curve analysis. Compared with those in the ineffective group, the values of cTnI and hs-CRP after treatment [cTnI (post) and hs-CRP (post) ], as well as their C and Cr values, were significantly decreased in the effective group (P<0.01). Furthermore, the positive rates (PR) of cTnI (post) , hs-CRP (post) , (cTnI+hs-CRP) (post) , C (cTnI) , C (hs-CRP) and C (cTnI+hs-CRP) were significantly lower in the effective group compared with those in the ineffective group (P<0.01). It was indicated that hs-CRP (post) and C (hs-CRP) , as well as the PR-cTnI (post) and the PR-C (cTnI) , may be used as independent factors for early therapeutic efficacy evaluation (P<0.05). In addition, the area under the ROC curve, as well as the associated sensitivity and specificity analysis for cTnI (post) , hs-CRP (post) , C (cTnI or hs-CRP) and Cr (cTnI or hs-CRP) , all indicated that these parameters were able to distinguish between the effective and the ineffective groups. The present study revealed that compared with the cTnI (post) and hs-CRP (post) , the C and the Cr of cTnI and hs-CRP may have enhanced value for evaluating the early therapeutic efficacy of AMI treatment.

Estimation of HsCRP and Cardiac Troponin I in Ischemic Heart Disease Iraqi Patients

“…The same result was observed by (Seyedian et al, 2016) study who reported that there was no significant difference between SA and HC groups. While in both UA and MI patients, the HsCRP marker could be reported very good indicators for patient's diagnosis, these results agree with (Seyedian et al, 2016) (23) study regarding to UA and agree with (Wang et al, 2020) study (24) which stated that the HsCRP has an important clinical value in the MI diagnosis. Also the present study observed that the HsCRP marker is always significant in the diagnosis between all the groups' combinations, as pointed by the many studies such as (23) , (25) and (24) studies.…”
