Objective To analyze the clinical application effect of evidence-based nursing in the nursing of elderly patients with acute left heart failure. Methods Patients with acute left heart failure in the cardiology department of our hospital were selected as the research samples. A sample size of 100 cases was screened. The collection time points were from February 2022 to February 2024. The patients were divided into two groups: 50 cases in the conventional care group received conventional care, and 50 cases in the evidence-based care group received evidence-based care. The vital sign indicators, cardiac function indicators, quality of life, clinical efficacy, occurrence of in-hospital respiratory tract infections, occurrence of adverse events and nursing satisfaction of the two groups were statistically analyzed. Results The LVEF and quality of life scores in the evidence-based nursing group were higher than those in the conventional nursing group (P<0.05), while the respiratory rate, heart rate, blood pressure, LVESD, LVEDD, and NT-proBNP levels were all lower than those in the conventional nursing group (P<0.05). The total effective rate was 90.00% (45/50), which was higher than 66.00% (33/50) in the conventional nursing group (χ2=4.812, P<0.05), and the incidence of nosocomial respiratory tract infection was 10.00% (5/50), which was lower than 30.00% (15/50) in the conventional nursing group (χ2=6.250, P<0.05). The incidence of adverse events was 6.00% (3/50), which was lower than 20.00% (10/50) in the conventional nursing group (χ2=4.332, P<0.05), and the nursing satisfaction rate was 96.00% (48/50), which was higher than 80.00% (40/50) in the conventional nursing group (χ2=6.061, P<0.05). Conclusion The effect of evidence-based nursing for elderly patients with acute left heart failure is relatively good.
