The purpose of this study was to investigate the prognostic value of dynamic changes of P-wave terminal force in lead V (PtfV ) at electrocardiogram (ECG) in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) during the long-term major adverse cardiovascular events (MACEs) of patients. According to the PtfV value, the patients were divided into four groups: PtfV (-)/PtfV (-), PtfV (-)/PtfV (+), PtfV (+)/PtfV (-), and PtfV (+)/PtfV (+). The highest incidence of MACEs was the PtfV (-)/(+) group with 24 patients (24.7%). The lowest incidence was the PtfV (-)/(-) group with 28 patients (4.9%). Compared with the PtfV (-)/(-) group, the risk for the occurrence of MACEs in the PtfV (-)/(+)group was significantly increased (24.7% vs 4.9%, P = .000). Similarly, the risk in the PtfV (+)/(+) group was also increased (10.1% vs 4.9%, P = .000). The persistence of PtfV (+) and conversion of PtfV /(-) to PtfV /(+) at discharge significantly increased the incidence of MACEs.
