D'Orio; COSTA, Roberto; TAMAKI, Wagner T.; CREVELARI, Elizabeth S.; PEIXOTO, Giselle De Lima; RAMIRES, Jose A. F.; KALIL, RobertoIntroductionMuscle sympathetic nerve activity (MSNA) is an independent prognostic marker in patients with heart failure (HF). Therefore, its relevance to the treatment of HF patients is unquestionable. ObjectivesIn this study, we investigated the effects of cardiac resynchronization therapy (CRT) on MSNA response at rest and during exercise in patients with advanced HF. MethodsWe assessed 11 HF patients (51 3.4 years; New York Heart Association class III-IV; left ventricular ejection fraction 27.8 2.2%; optimal medical therapy) submitted to CRT. Evaluations were made prior to and 3 months after CRT. MSNA was performed at rest and during moderate static exercise (handgrip). Peak oxygen consumption (VO2) was evaluated by means of cardiopulmonary exercise test. HF patients with advanced NYHA class without CRT and healthy individuals were also studied. ResultsCRT reduced MSNA at rest (48.9 +/- 11.1 bursts/min vs 33.7 +/- 15.3 bursts/min, P < 0.05) and during handgrip exercise (MSNA 62.3 +/- 13.1 bursts/min vs 46.9 +/- 14.3 bursts/min, P < 0.05). Among HF patients submitted to CRT, the peak VO2 increased (12.9 +/- 2.8 mL/kg/min vs 16.5 +/- 3.9 mL/kg/min, P < 0.05) and an inverse correlation between peak VO2 and resting MSNA (r = -0.74, P = 0.01) was observed. ConclusionsIn patients with advanced HF and severe systolic dysfunction: (1) a significant reduction of MSNA (at rest and during handgrip) occurred after CRT, and this behavior was significantly superior to HF patients receiving only medical therapy; (2) MSNA reduction after CRT had an inverse correlation with O-2 consumption outcomes.

C.; HIGA, K.; NOMURA, C.; MARTINELLI FILHO, M.; COSTA, R.- Quality of Life and Functional Capacity after Long-Term Right Ventricular Pacing in Pediatrics and Young Adults with Congenital Atrioventricular Block(2013) SILVA, Katia Regina da; COSTA, Roberto; OLIVEIRA JR., Roberto Marcio De; LACERDA, Marianna Sobral; HUANG, Adriana I. Un; ROSSI, Marina Bertelli; CREVELARI, Elizabeth Sartori; TAMAKI, Wagner Tetsuji; MARTINELLI FILHO, Martino; PIETROBON, RicardoBackgroundAlthough several studies have demonstrated deleterious consequences of chronic right ventricular (RV) pacing on ventricular function and synchronicity, its effects on health-related quality of life (HRQoL) and functional exercise capacity remain uncertain. We aimed to evaluate the effect of RV pacing on HRQoL and functional capacity of children and young adults with congenital complete atrioventricular block (CCAVB). MethodsWe included 66 consecutive subjects with RV cardiac pacemaker due to CCAVB and under clinical follow-up for more than 1 year. Multidimensional HRQoL scores were evaluated by Short Form-36 Health Survey (SF-36) and Child Health Questionnaire-Parent Form 50 (CHQ-PF50). Functional capacity was tested by a 6-minute walk distance test (6MWDT). Association analysis was performed to examine if any demographic and clinical characteristics were associated with lower HRQoL scores and shorter distances at the 6MWDT. ResultsDomains presenting lower HRQoL scores were vitality (64.0 17.3), mental health (67.3 +/- 8.0), role emotional (69.7 +/- 35.8) in the SF-36 questionnaire; general health perceptions (61.3 +/- 8.3), general behavior (61.9 +/- 15.6), parental impactemotional (67.7 +/- 28.7) in the CHQ-PF50. Female gender (P = 0.009), left ventricular ejection fraction lower than 55% (P = 0.013), cardiovascular drugs (P = 0.003) were significantly associated with lower HRQoL scores. Average distance traveled during the 6MWDT was 539.8 +/- 82.9 m. The 6MWDT showed significant association with age (P = 0.006) and cardiovascular drugs (P = 0.024). ConclusionsChronic RV pacing did not affect the HRQoL and physical capacity of pediatrics and young subjects. Female gender, ventricular function, and cardiovascular drugs were associated with lower HRQoL scores. Older subjects walked shorter distances in the 6MWDT, as well as subjects who were taking cardiovascular drugs.
