Correlation of serum cardiac troponin levels and cardiovascular events in elderly type 2 diabetes patients / 中华老年医学杂志

ABSTRACT

Objective To study the correlation of serum cardiac troponin levels and cardiovascular events in elderly type 2 diabetes patients,and provide the basis for prevention and treatment of cardiovascular disease combined with type 2 diabetes mellitus.Methods Totally 200 elderly type 2 diabetes patients were selected in the First Affiliated Hospital of Zhengzhou University,and divided into cardiac troponin-positive and negative groups according to serum cardiac troponin levels.The incidence of cardiovascular events and mortality was compared between the two groups.Results The levels of fructosamine and hemoglobin in cardiac troponin-positive group were significantly lower than those of cardiac troponin-negative group (P＜0.05).The C-reactive protein levels were increased in cardiac troponin-positive versus negative group (P ＜0.05).The incidences of cardiovascular events and mortality in cardiac troponin-positive group showed higher than those of cardiac troponin-negative group[63.3％ (19/30)vs.4.1 ％ (7/170),26.7％ (8/30) vs.1.2％ (2/170),x2 =73.45,28.44,all P＜0.05].Conclusion Lower levels of serum fructosamine and hemoglobin,higher C-reactive protein level exist in diabetes patients with high cardiac troponin levels.The serum cardiac troponin level has a certain relationship with cardiovascular events in diabetes patients.
