Differences in clinical features,in-hospital treatment and outcomes of heart failure patients with different age shock indexes
Objective:To analyze the clinical features,in-hospital treatment and 12-month outcomes of heart failure inpatients with different age shock indexes (ASI).Methods:A total of 259 heart failure patients aged over 18 years who were admitted in the Second Affiliated Hospital of Baotou Medical College from October 2020 to November 2021 were consecutively included in this study.The baseline data were collected and ASI (age × heart rate/systolic blood pressure)was calculated on the day of admission.Patients were divided into the high ASI (n=129)and low ASI group (n=129).Clinical features of the two groups of patients,differences in hospital treatment and outcomes of 12 months after discharge,and correlation between ASI and the risk for all-cause mortality 12 months after discharge in patients were analyzed.Results:Lower body mass index,systolic blood pressure,diastolic blood pressure and left ven-tricular ejection fraction value were found in the High ASI group of patients,with thinner left ventricular posterior wall and higher brain natriuretic peptide and white blood cell count.More patients in the high ASI group took β-blockers o-rally and used inotropes and diuretics intravenously than in the low ASI group (P<0.05).12 months after discharge,patients in the high ASI group had more rehospitalizations (34.9％)and all-cause deaths (23.3％),and a higher risk of all-cause death after 12 months.(HR=3.05,95％CI:1.25～7.45,P=0.014).Conclusion:Patients in the high ASI and low ASI groups had different clinical characteristics and similar treatments during hospitalization.The risk of all-cause death 12 months after discharge was higher in patients with high ASI than patients with low ASI.ASI was an independent risk factor for long-term prognosis of hospitalized patients with heart failure.
