The observation of cardiac troponin T in hemodialysis patients / 中华老年医学杂志

ABSTRACT

Objective To observe the possible relationship of cardiac troponin T (cTnT) with cardiac disease and death events in hemodialysis patients Methods The cTnT was measured with dry chemical method in 57 hemodialysis patients The patients were followed up for one year Results The concentration of cTnT was more than 0 10 ?g/L in 12 of the 57 unselected hemodialysis patients 8 in the 12 patients were diagnosed as diabetes mellitus 7 of 12 patients died and the death reason was acute left ventricular failure(33 3%) in 4 patients In other 45 patients with normal cTnT, 3 died and only 1 died of heart failure(2 22%) The cTnT concentrations of pre-and post-hemodialysis were measured in 24 patients The concentration was more than 0 1 ?g/L in 6 patients before dialysis Post-dialysis concentration was increased in 5 patients', the value was decreased in the other one Conclusions In hemodialysis patients without acute myocardial infarction, mortality and cardiovascular events are closely correlated with the increase of cTnT concentration. Patients with diabetes mellitus have higher incidence in the abnormality of cTnT concentration.The process of hemodialysis does not affect the concentration of cTnT.
