ObjectiveTo investigate the mid-to-long term quality of life (QOL) and influencing factors in the patients after heart valve replacement.MethodsConvenient sampling method was used to recruit 224 patients who had heart valve replacement surgery in our hospital from June 2008 to June 2017. There were 63 males and 161 females, aged 18-83 (51.49±10.60) years. General information questionnaire and MOS SF-36 scale were used to collect data. Univariate analysis and multiple linear regression analysis were used to analyze and determine the influencing factors for the QOL.ResultsThe total score of QOL of 224 patients was 71.78±17.60 points. All these scores of the patients were significantly lower than those of the general population of Chengdu (P<0.05) except the dimension of vitality. The QOL scores differences between sex, marital status, family income, working condition, the occurrence of anticoagulant complications and other complications were significant (P<0.05). Multivariate analysis showed that family income, working condition, the occurrence of anticoagulant complications and other complications could be included in the regression model, explaining 26.8% of total variance. ConclusionThe mid-to-long term QOL is lower in the patients after heart valve replacement. Family income, working condition, anticoagulant complications and other complications are the main influencing factors for mid-to-long term QOL for patients after heart valve replacement.
