Objective:To explore influence of evidence -based nursing mode on lifestyle and negative emotion in aged pa‐tients with coronary heart disease (CHD) .Methods:A total of 88 CHD patients treated in our department of cardiology were selected .According to random number table ,they were randomly and equally divided into routine nursing group and evidence-based nursing group (received evidence -based nursing based on routine nursing ) . Unhealthy lifestyle status , negative emotion score ,nursing satisfaction and incidence rate of adverse events were recorded and compared between two groups before and four weeks after intervention .Results:Compared with routine nursing group after intervention ,there were significant reductions in percentages of smoking (40.9% vs .22.7% ) ,drinking (54.5% vs .38.6% ) ,high fat diet (43.2% vs .29.5% ) ,physical inactivity (45.5% vs .25.0% ) and overweight or obesity (52.3% vs .29.5% ) in evidence‐based nursing group , P<0.05 all;compared with before intervention ,there were significant reductions in scores of self -rating anxiety scale (SAS) and self-rating depression scale (SDS) in both groups after intervention(P<0.05 or <0.01) , and compared with routine nursing group ,scores of SAS and SDS significantly reduced in evidence -based nursing group , P<0.05 all .Compared with routine nursing group ,there was significant rise in nursing satisfaction (86.4% vs .97.7% ) and significant reduction in incidence rate of adverse events (25.0% vs .11.4% ) in evidence -based nursing group , P<0.05 all .Conclusion:Evidence-based nursing can effectively reduce unhealthy lifestyle and remit the negative emotional state in aged CHD patients ,which is worth extending in clinic .
