ABSTRACT
Objective: To understand the cardiac involvement of Dengue fever patients and to analyze the clinical characteristics of Dengue fever combining cardiac complications. Methods: A total of 395 patients of Dengue fever treated in our hospital were analyzed. Blood levels of CK, CK-MB, CTnT, NT-proBNP were examined, ECG and echocardiography (UCG) were conducted in all patients. Upon Dengue recovery, the levels of CK and CK-MB were re-examined in patients with elevated indexes. Results: Overall, there were 47.3% patients with increased CK, 61.3% with increased CK-MB, 42.5% with increased CTnT and 22.4% with increased NT-proBNP; 37.2% patients with abnormal ECG and 29.9% with abnormal UCG. There were 65.5% patients showing CK and CK-MB reduction more than 4 days upon Dengue recovery. Compared to those without the history of heart disease (HD), the patients with HD history had the higher abnormal rates of CTnT (17.7 vs 60.8) %, NT-proBNP (4 vs 32.3) % and ECG (25.1 vs 51.7) %, UCG (15.7 vs 41.7) %, allP Conclusion: Blood levels of CK, CK-MB, CTnT, NT-proBNP and ECG, UCG could be used to evaluate the patients with Dengue fever in order to prevent the cardiac complications at the early stage.
