Pacemaker implications in the functional capacity and quality of life of cardiopathic patients

Abstract Introduction: Cardiovascular diseases are among the main causes of death, and in recent years there has been an increase in pacemaker implants (PM), which is intended not only to increase survival, but also to improve quality of life. Objective: To evaluate the quality of life, cardiorespiratory fitness and level of physical activity of patients before and after permanent PM implant in a large hospital in the north of the state of Rio Grande do Sul. Method: The study comprised 19 patients submitted to PM surgery who had their electronic health record and quality of life (AQUAREL) evaluated as well as their cardiorespiratory fitness and the limit of daily physical activity (VSAQ), peripheral muscle strength (PMS), respiratory muscle strength (manovacuometry), their degree of dyspnea (modified PMS) and the hemodynamic parameters, all of which were assessed in the preoperative period and after 30 days. Results: A mean age of 71.79 years was observed and in 63.1% of the cases Total Atrioventricular Block was the pathology, while 89.5% of the participants presented systemic arterial hypertension and 31.6% also presented Diabetes Melittus. Statistically significant improvement was observed in all the values under evaluation, namely: dyspnea (p = 0.0001), peripheral muscle strength (p = 0.0001) and respiratory muscle strength (PIMAX p = 0.0001 and PEMAX p = 0.0001), Quality of Life (p = 0.0001) and Cardiorespiratory Fitness and level of physical activity p=0.0001). Conclusion: Improvement was verified in all parameters analyzed, thus suggesting that the PM positively influences the quality of life and the functionality of the patients. Resumo Introdução: As doenças cardiovasculares estão entre as principais causas de mortes, e nos últimos tempos observa-se aumento nos implantes de marcapasso cardíaco definitivo (MP), sendo que esse visa não apenas aumentar a sobrevida, mas também a qualidade de vida. Objetivo: Avaliar a qualidade de vida, a aptidão cardiorrespiratória e nível de atividade física de pacientes antes e após o implante de MP em um hospital de grande porte do norte do estado do Rio Grande do Sul. Método: O estudo contou com 19 pacientes submetidos ao MP, onde avaliou-se o prontuário eletrônico, a qualidade de vida (AQUAREL), a aptidão cardiorrespiratória e o nível limite de atividade física diária (VSAQ), a força muscular periférica (MRC), a força muscular respiratória (manovacuometria) o grau de dispneia (MRC modificado) e os parâmetros hemo
