Abstract:
To explore predictive value of fragmented QRS wave (fQRS) for prognosis in patients with a‐cute no ST elevation myocardial infarction (NSTEMI).Methods : According to ECG measure result , 120 NSTEMI patients treated in our hospital from Jan 2015 to Feb 2017 were divided into fQRS group (n＝73) and no fQRS group (n＝47).Both groups received same treatment .General information and incidence of MACE during one‐year fol‐low‐up were compared between two groups .Results : There were no significant difference in heart rate ,percentage of dyslipidemia ,hypertension and diabetes mellitus between two groups ( P＞ 0. 05 all).Compared with no fQRS group ,there were significant reduction in left ventricular ejection fraction [(63. 81 ± 5.67)% vs.(52. 18 ± 5. 81)%, P＝0. 001] , and significant rise in percentage of previous myocardial infarction (21.28% vs.39. 73%, P＝0.035) and more than three coronary stenosis greater than or equal to 50%(36.17% vs.54.79%, P＝ 0.046) in fQRS group .Compared with no fQRS group ,incidence of MACE of fQRS group was higher (25. 53% vs.45.21%, P＝0.030).Conclusion :Cardiac function of NSTEMI patients with fQRS is significantly poorer than that of patients without fQRS ,so patients with fQRS predicts their state of an illness is serious and prognosis is poor .
