Abstract：Objective To explore the predictive effect of heart rate turbulence(HRT) on longterm prognosis of old myocardial infarction(OMI) patients. Methods A total of 127 OMI patients who had been admitted in our hospital from March 2014 to June 2015 were selected.[JP] According to the range of Nterminal probrain natriuretic peptide(NT-proBNP) value and HRT, they were classified into NT-proBNP＜1 800 ng/L group and NT-proBNP≥1 800 ng/L group, and HRT normal group(TO＜0 and TS＞2.5) and HRT abnormal group[TO≥0 and(or) TS≤2.5]. In the follow-up one year later, the incidences of major adverse cardiovascular events(MACE) were analyzed statistically; the difference and relativity of MACE incidences between HRT normal group and HRT abnormal group, HRT normal group and NT-proBNP＜1 800 ng/L group, and HRT abnormal group and NT-proBNP≥1 800 ng/L group were separately compared. Results The incidences of MACE(except for the rate of sudden death) in HRT abnormal group were all significantly higher than those in HRT normal group, with statistically significant differences. However, neither of the differences of MACE incidences(except for the rate of sudden death) between HRT normal group and NT-proBNP＜1 800 ng/L group, and HRT abnormal group and NT-proBNP≥1 800 ng/L group was statistically significant. Conclusion HRT has some predictive effect on longterm prognosis of OMI patients. The difference of predictive effect between HRT and NT-proBNP is not obvious.
