In another study, altered thermoregulatory responses in heart failure patients exercising in the heat was analysed.
“Heart failure (HF) patients appear to exhibit impaired thermoregulatory capacity during passive heating, as evidenced by diminished vascular conductance,” noted the study.
It continued: “This is the first study to examine both the thermoregulatory responses and heat balance parameters in HF during exercise.
“Our findings show that when exercising in a warm environment, HF had comparable changes even though metabolic heat production per unit mass was greater.
“These findings demonstrate for the first time that thermoregulatory capacity in HF is disrupted during exercise combined with a thermal challenge.”
