Which risk increases when a hibernating mammal’s shivering thermogenesis rapidly intensifies after arousal?

💡 Explanation

When shivering thermogenesis intensifies, it causes rapid metabolic rate increase mobilizing calcium rapidly, increasing platelet reactivity and blood viscosity, potentiating clot formation potentially causing myocardial infarction. Therefore myocardial infarction is the risk, rather than other listed organ failures occurring via completely different mechanisms.

• Which outcome directly limits long-duration high-altitude avian flight when air sacs cannot fully inflate?
• Which outcome reduces lion hunting success with increased density of spotted hyenas?
• Which outcome occurs when a marine mammal dives into icy water and surface blood vessels experience dramatic vasoconstriction?
• Which physiological outcome occurs when a mammal experiences prolonged exposure to high ambient temperatures influencing thermoregulation?
• Which navigational error occurs when polarized light availability changes, impairing the location 'maps' used by migrating monarch butterflies?
• Which outcome occurs when vessel element cavitation interrupts cohesion-tension?
