Background
The purpose of this study was to investigate the prognostic value of dynamic changes of P‐wave terminal force in lead V
1
(PtfV
1
) 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.
Methods
According to the PtfV
1
value, the patients were divided into four groups: PtfV
1
(−)/PtfV
1
(−), PtfV
1
(−)/PtfV
1
(+), PtfV
1
(+)/PtfV
1
(−), and PtfV
1
(+)/PtfV
1
(+).
Results
The highest incidence of MACEs was the PtfV
1
(−)/(+) group with 24 patients (24.7%). The lowest incidence was the PtfV
1
(−)/(−) group with 28 patients (4.9%). Compared with the PtfV
1
(−)/(−) group, the risk for the occurrence of MACEs in the PtfV
1
(−)/(+)group was significantly increased (24.7% vs 4.9%,
P
= .000). Similarly, the risk in the PtfV
1
(+)/(+) group was also increased (10.1% vs 4.9%,
P
= .000).
Conclusion
The persistence of PtfV
1
(+) and conversion of PtfV
1
/(−) to PtfV
1
/(+) at discharge significantly increased the incidence of MACEs.
