Background
Because of the establish and maintain green channel for patients with acute chest pain, the mortality of fatal chest pain such as myocardial infarction has decreased. There are still some patients with chest pain, such as acute pulmonary embolism(PE) and acute aortic dissection(AAD), which is very easy to miss diagnosis and misdiagnosis. Therefore we establish a new modified HEART score for fatal chest pain risk stratification in emergency department to judge the prognosis of patients.
Methods
There were 541 patients enrolled in Yixing people’s Hospital from November 2018 to June 2020 at Department of Cardiology, Yixing people’s hospital. All patients were detailed medical history, years old, risk factors, hypertension and were detected by blood pressure, ECG, troponin, cardiac function, D-dimer. All patients with chest pain were scored by using HEART score and a new modified HEART score.
Results
A total of 317 patients with non fatal chest pain were divided into low-risk group, medium-risk group and high-risk group according to HEART score and modified HEART score. The results showed that the proportion of three groups were no significant difference. In 224 cases of fatal chest pain patients, according to the HEART score and modified HEART score, they were divided into three groups: low-risk group, medium risk group and high-risk group. The results showed that the proportion of low-risk group was no significant difference. The proportion of patients diagnosed as medium risk group was significant difference(36.16% vs 12.50%, p < 0.05). The proportion of high-risk group was significant difference(57.59% vs 82.59%, p < 0.05). The area under Receiver Operating Characteristic curve(ROC) evaluate new modified HEART score for the prognosis of fatal chest pain. The area under ROC curve of new modified HEART score were 0.975 (95%CI 0.964–0.987, p < 0.001), the best cut-off point was 5 scores, sensitivity and specificity were 90.7% and 93.3%.
Conclusion
Our study demonstrated that a new modified HEART score can effectively and rapidly distinguish fatal chest pain and can play an important role in the prognosis of patients with chest pain in emergency department.
