RESUMO
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...
ABSTRACT
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...
