[Association between serum cardiac troponin I and myocardial remodeling in patients with chronic heart failure].
OBJECTIVE
To investigate the association between serum cardiac troponin I (cTnI) and cardiac function/structure in patients with chronic heart failure.


METHODS
One hundred and twenty patients with decompensated chronic heart failure were included. The patients were divided into cTnI normal group (cTnIn; n = 80) and cTnI elevated group (cTnIe; n = 40). Systolic dimension of the left atrium (LAd), the maximal width of the left ventricle (LVd), the thickness of the interventricular septum (IVS) and posterior wall (LVPW) during diastole, left ventricle ejection fraction (LVEF), E and A wave velocities ratio (E/A) were determined. Bivariate correlation analysis was applied to show the correlation of serum cTnI level with above indices. Partial correlation analysis was performed followed by multivariate logistic regression.


RESULTS
LAd and LVd dimensions were significantly higher (P < 0.05), IVS, LVPW, LVEF and E/A ratio were significantly lower (P < 0.05) in cTnIe group than in cTnIn group. Moreover, serum cTnI was positively correlated with LAd, LVd, and inversely correlated with IVS, LVPW, LVEF and E/A ratio (P < 0.05). The correlation persistent after adjusting with sex, history of heart failure, NYHA functional class and treatment. In multivariate modeling, cTnI was positively associated with LAd, LVd and the history of heart failure, and negatively related with the treatment with angiotensin-converting enzyme inhibitor.


CONCLUSIONS
Serum cTnI correlated with cardiac structure and function. Intensively serum cTnI monitoring and suitable therapy strategy may be helpful to attenuate the cardiac remodeling in patients with chronic heart failure.
