Condicionamento físico precoce de pacientes submetidos à cirurgia de revascularização do miocárdio. Influência sobre a capacidade funcional / Early physical conditioning of patients surgically treated for myocardial revascularization. Influence on the functional capacity

PURPOSE--To evaluate the early physical conditioning (PC) effect [initiated 15 days after the myocardial revascularization surgery (MRS)] in the functional capacity. METHODS--Twenty-two male patients (mean-age of 52y-o), divided in two groups (A and B, 11 patients each), were studied. Group A started PC 3 months after MRS (phase III), with a training intensity of about 70 of the maximum heart rate reserve, during three months, three sessions per week with one hour duration. Group B started PC 15 days after the MRS (fase II), with a training intensity up to five metabolic unities, three times a week, 1 hour and 15 duration. The post-MRS period of three months was designated as the time I (beginning of fase III) and six months as time 2. Stress test, Kraus-Weber flexibility test, coxo-femural flexibility test (flexion, elevation and abduction) and scapule-umeral flexibility test (flexion, extension and abduction) were applied. RESULTS--The maximum oxygen uptake and the total work increased significantly from time 1 to time 2 in both groups, but there was no significant difference between the two groups, either in time 1 or 2. Flexibility in the Kraus-Weber test and in the scapule-umeral flexibility test when in flexion, were significantly greater in group B than A, in both times (1 and 2). Other flexibility variables studied show no significant difference, neither between the studied groups nor in the times 1 and 2 of evaluation. CONCLUSION--Early PC after MRS increased the value of two variables that measure flexibility. However, it has not increased other flexibilities variables and the aerobic capacity.

Ergoespirometria como método de prediçäo do comportamento evolutivo da miocardiopatia isquêmica, chagásica e idiopática / Spyroergometry a prediction ethod to evaluate patients with ischemic, chagas disease and idiopathic cardiomyopathy

Objetivo—Comparar e avaliar as modificações das variáveis obtidas pela ergoespirometria em grupos de pacientes portadores de miocardiopatia de etiologia isquêmica (IS), por doença de Chagas (CH) e idiopática (ID). Estudar a tolerância às condições anaeróbias em pacientes que foram a óbito entre os grupos acima descritos. Métodos Estudaram-se 50 indivíduos do sexo masculino, dez dos quais eram sadios e 40 portadores de miocardiopatia com insuficiência cardíaca (IC) compensada. Dentre os miocardiopatas, nove faleceram (subgrupo OB) no período de estudo que se estendeu a 1.005 dias. Estes foram comparados ao subgrupo NOB, formado pelos 31 pacientes restantes. Estes pacientes foram avaliados em 4 condições: repouso (REP), limiar anaeróbio (LA), pico de esforço (P) e recuperação no 4º minuto (REC). A investigação constou do estudo de dados obtidos por meio de ergoespirometria; consumo de O2 (Mets), produçao de CO2 (VCO2 ), equivalente respiratório de O2 (VE/VO2), pulso de O2 (VO2 / FC) e o tempo decorrido entre o LA e o ponto P. Resultados Houve diferença siginificativa quando os três grupos patológicos (IS, CH, ID) foram comparados com o grupo controle (N). Não houve diferença significativa quando os três grupos patológicos foram comparados entre si. Em relação a tolerância às condições anaeróbias houve diferença significativa entre os pacientes do subgrupo NOB...

Purpose To compare and evaluate the modifications variables obtained through spyroer gometry in groups of patients with ischemic cardiomyopathy (IS), Chagas disease (CH), and idiopathic cardiomyopathy (ID). To study tolerance to anaerobic conditions of patients from the above groups who died. Methods A study was carried with 50 male patients, 10 of which were found in normal conditions whereas 40 presented cardiomyopathy with compensated heart failure. We observed that from the 40 patients from the cardiomyopathy groups, nine died, subgroups OB—during the study period of 1.005 days. These were compared to subgroups NOB—the remaining 31 patients. These patients were evaluated under 4 conditions—Rest (Rep), anaerobic threshold (LA), power peak of the exercise (P) and in the fourth minute recovery (REC). The investigation was based on data collected by means of spyroergometry: oxygen consumption (MET), production of CO2 (VCO2), respiratory equivalent of oxygen (VE/ VO2), oxygen pulse (VO2 /FC) and the time elapsed between LA and P. Results—There were significant differences when the three pathological groups (IS, CH, ID) were compared with the control groups (N). There were no significant differences when the three pathological groups compared among themselves. In relation to tolerance to anaerobic conditions significant differences were found among the patients of subgroup OB—1.33 minwho died when compared to subgroup...
