Impact on the quality of life after mitral clip implantation

Abstract

Abstract Background and objectives Mitral regurgitation is a very limiting disease for the patient. The objetctive is to analitze the effectiveness of the mitral clip implantation on the quality of life and the degree of dependence in patients with mitral regurgitation Methods Almost experiment study of time series. The quality of life was evaluated with the Minnesota Living With Heart Failure (MLWHFQ) and Short-Form 36 (SF-36) questionnaire, 6 months before the intervention, 1 day before, 1 month after and 6 months later. The degree of dependence was evaluated with the Katz Index. The intervention was considered effective when the MLWHDQ decreased in 10 points and/or the Katz Index 1 point. Other variables were socio-demographic and clinical factors Results Twenty patients were introduced with a mean age of 78,6 ± mostly men (75%) and with very prevalent cardiovascular risk factors. The total MLWHFQ score decreased significantly after the intervention by 26.63 points (p = 0.004) and in the physical dimension by 12.13 points (p = 0.004) and 5.75 points (p = 0.007). In contrast, the modification of the score in the Katz Index was 0.14 points (p = 0.257) There was a significant decrease in pre and post intervention symptoms: dyspnea (p = 0.063), fatigue (p = 0.000) and maleolar oedema (p = 0.063) In the SF-36 health transition question, 75% of patients reported feeling better or much better after 6 months of the intervention. Conclusions These results suggest that mitral clip implantation improves short-term quality of life in patients with mitral insufficiency, although it doesn"t change the degree of dependence for short-term daily life activities. In addition, mitral clip implantation improves the limiting symptoms of these patients and the health perception at 6 months.
