Abstract in Portuguese
Inúmeros problemas cotidianos estão mal esclarecidos para portadores de marcapasso cardíaco definitivo (MCD). Dentre eles, destaca-se sua relação com atividades físicas e programas de treinamento. Este estudo, PRACTICING - Physical Training Effect In Pacemaker Patients, tem o objetivo de avaliar o impacto do treinamento físico sobre o consumo de oxigênio (VO2 pico) e a qualidade de vida em portadores de MCD. Métodos - estudo prospectivo, unicêntrico e randomizado que incluiu portadores de MCD atrioventricular com funções sinusal e ventricular normais, sedentários, com idade entre 18 e 80 anos. Os pacientes foram distribuídos em três grupos: GTFS - grupo treinamento físico supervisionado; GTFNS - treinamento físico não supervisionado e GC - controle. Foram analisadas as variáveis obtidas por teste ergoespirométrico (TEE) e questionários de qualidade de vida (SF36 e Aquarel), no inicio do estudo e após 4 meses de seguimento. Resultados - Foram incluídos 18 pacientes no GTFS; 20 no GTFNS e 20 no GC. A idade média foi 55,4 ± 10 anos, 69,0% era do sexo feminino e a FEVE média foi 63,41 ± 5,0%. Hipertensão arterial, diabetes mellitus e doença de Chagas estiveram presentes em 56,9%, 25,8% e 25,9%, respectivamente. O tempo médio de uso de MCD foi de 59,4 ± 62,6 meses. O VO2máx médio inicial da população foi de 24,0 ± 5,8ml/kg/min e não houve diferença entre os três grupos (P=0,279). Apenas no GTFS ocorreu melhora significativa no VO2máx após treinamento físico: 23,86±4,38 versus 26,74 ± 4,18 ml/kg/min, (P=0,001). A avaliação da qualidade de vida demonstrou apenas diferença no domínio desconforto no peito no GTFNS e dispneia no GC (Aquarell). Conclusão - Em portadores de MCD sem disfunção ventricular, o treinamento físico supervisionado proporcionou melhora expressiva do consumo de oxigênio e de suas repercussões funcionais, embora com baixo impacto na qualidade de vida

Abstract in English
Many everyday problems are poorly cleared for permanent cardiac pacemaker (MCD). Among these, there is its relation to physical activities and training programs. This study, PRACTICING- Physical Training Effect In Pacemaker Patients - aimed to assess the impact of physical training on the oxygen uptake (VO2 peak) and the quality of life in patients with MCD. Methods - prospective, singlecenter, randomized trial that included patients with atrioventricular MCD with sinus function and ventricular normal, sedentary, aged between 18 and 80 years. Patients were divided into three groups: GTFS - group supervised physical training; GTFNS - physical training unsupervised and GC - control. We analyzed the variables obtained by cardiopulmonary exercise test form (TEE) and quality of life questionnaires (SF36 and Aquarel) at study start and after four months of follow-up. Results - We included 18 patients in GTFS; 20 in GTFNS and 20 in the control group. The mean age was 55.4 ± 10 years, 69.0% were female and the mean LVEF was 63.41 ± 5.0%. hypertension, diabetes mellitus and Chagas disease were present in 56.9%, 25.8% and 25.9%, respectively. The average time of use of MCD was 59.4 ± 62.6 months. The initial average VO2max of the population was 24.0 ± 5,8 ml/kg/min and there was no difference among the three groups (P = 0.279). Only in GTFS was significant improvement in VO2max after physical training: 23.86 ± 4.38 versus 26.74 ± 4,18 ml/kg/min (P = 0.001). The evaluation of quality of life, demonstrated only difference in discomfort in the chest area in GTFNS and dyspnoea in CG (Aquarell). Conclusion - In patients with MCD without ventricular dysfunction, physical training protocol supervised provided significant improvement in oxygen uptake and its functional repercussions, albeit with low impact on quality of life
