How long can hyperdynamic cardiac dysfunction last after a burn injury?

Hyperdynamic cardiac dysfunction following a burn injury can indeed last for an extended period, potentially spanning months to years. This is primarily due to the physiological changes and stress response that occur within the body after significant burns. When a patient experiences a serious burn, the body's metabolic demands increase dramatically. This heightened state can lead to long-term cardiovascular effects, including sustained increases in cardiac output and heart rate, in an effort to meet the metabolic needs of healing tissues and combating stress-related responses.

Moreover, the systemic inflammatory response triggered by the burn injury can contribute to ongoing stress on the heart and circulatory system, prolonging dysfunction beyond the acute phase of recovery. Even after the initial healing has progressed, some patients may continue to exhibit signs of hyperdynamic dysfunction, driven by factors such as lingering inflammatory mediators, changes in fluid volume status, and alterations in vascular resistance.

Understanding this long-term potential helps medical professionals monitor and manage cardiovascular health in burn patients beyond the immediate recovery phase.
