Abstract :

Objective To explore the early warning of acute aggravation in discharged patients with chroninc heart failure. Methods Patients of chronic heart failure with reduced effection fraction (HFrEF) were selected from consecutive cases discharged from Songshan hospital in 2016 to 2020. A follow-up table of integrals (EWI, early warning Integral) according to the ralative factors of pathogenesis, inducement, EF, early sympotum, early sign and BNP level was designed to investigate retrospectivly the latest acute aggravation before hospitalization. Logistic regresion was used to defi ne early warning factors and their judgement criterium. Results Altogether 100 patients were selected from 105 consecutive discharged patients. Male/female was 46/54 with age 63.5±7.6 years and EF 41.3±5.2%. Annual hospitalization was 1.8±0.7 times. All patients complicated with organic heart disease and most of them were atrial fi brillation, hypertension, coronary heart disease and degenerative valvular disease (18%-56%). Regression showed that early acute aggravation was signifi cantly related to pathogenesis 0.89, EF0.87, overwork 0.83, aggravated edema 0.72, shortness of breath 0.68, declined activity 0.56 (P<0.05-0.01). EWI was designed according to 2 major factors (organic heart disease and reduced EF 2 scores in each ) and at least 1/4 minor factors (overwork, aggravated edema, shortness of breath, declined activity 1 score in each). A score larger than 5/8 suggests strongly high risk of early acute aggravation of chronic HFrEF. Subsequent BNP tests were positive in the whole group of patients.

Biography :

Discharged patients with chronic HFrEF exist identifi nable sigh of early warning. EWI could be used to fi nd their early acute aggravation. Defi ned diagnosis could be made by subsequent BNP test.
