To explore the Heart risk score in predicting 30-day major adverse cardiovascular events (MACE) for the patients with acute chest pain in the emergency department.
There are 209 Patients presented to emergency department with acute chest pain included. Clinical data and Heart scores were collected from the original data. All causes leading to MACE were followed up at 30 days by Health Insurance Information System and call interview.
The Heart risk score in MACE patients were significantly higher than that in non MACE patients(P<0.05), as well as the age, hypertension, ACS, SPO2 and the number of in-patient. However, the blood pressure at the admission of MACE patients was significantly decreased than that in non MACE patients(P<0.05). The incidence ratio of MACE within 30 days was 5.74%, and the area under the curve(AUC) for 30-day MACE was 0.908(95% CI: 0.846 to 0.974). Meanwhile the sensitivity was 83.33% and specificity was 86.29% when the cutoff value of heart risk exceeded 6. Within 30 days, the percent of MACE in patients with Heart risk scores between 0 to 3, 4 to 6 and 7 to 10 was 0%, 2.5% and 27%, respectively.
Heart risk scores maybe a simply, rapidly and accurately rule to predict MACE within 30 days for the patients with acute chest pain presenting to emergency department, and plays an important role in effective elimination MACE for low-risk patients.
