Abstract: Objective:To explore the effects of authorized education combined with family support on the self-care ability and compliance behavior in patients with acute myocardial infarction(AMI) during convalescence.Methods:Eighty-four patients with AMI during convalescence were divided into the observation group(n=42) and control group(n=42) according to the random number table.The control group was nursed with routine method,and the observation group was nursed with authorized education combined with family support based on control group.The levels of self-care ability,compliance behavior,quality of life in two groups were evaluated using self-care ability(ESCA) scale,compliance behavior questionnaire and angina pectoris quality of life scale(SAQ) before and after intervention.Results:The differences of the self-care ability and each dimension scores between two groups before intervention were not statistically significant(P>0.05).After intervention,the self-care ability and each dimension scores in two groups were improved(P<0.05 to P<0.01),and which in observation group was significantly higher than that in control group(P<0.01).After intervention,the compliance behavior rate(including reasonable diet,timely medication,suitable exercise,regular checking,giving up smoking and limiting alcohol) in observation group was significantly higher than that in control group(P<0.01).The differences of the SAQ and each dimension scores between two groups before intervention were not statistically significant(P>0.05).After intervention,the SAQ and each dimension scores in two groups were improved(P<0.05 to P<0.01),and which in observation group was significantly higher than that in control group(P<0.01).Conclusions:Authorized education combined with family support can effectively improve the self-care ability and compliance behavior of AMI patients,so as to improve the quality of life of patients.
