1. Chemoreflex modulation by hypoxia and hypercapnia through submaximal exercise in heart failure patients / "Modulação do quimioreflexo por hipóxia e hipercapnia durante exercício submáximo na insuficiência cardíaca"
Heart failure(HF) dyspnea is complex with potential enrolment of central(CC) and peripheric chemoreceptors(PC).We investigated CC and CP behavior through submaximal exercise in 15 HF patients and 7 normal subjects in treadmill 6-minute cardiopulmonary walking tests:isocapnic hypoxia(HPO), hypercapnia hyperoxic(HCP) and room air.HPO increased:ventilation(VE)
