Boxer Karol Itauma says a heart attack halted his promising career after doctors told him to stop, warning that continuing could be fatal. In interviews, he describes the shock of the medical scare and the decision to end boxing as part of his recovery and long-term health planning.

Afterward, Itauma shifts from competing to working on public-facing health initiatives. He co-founds Club Eight Three, a project he presents as focused on health and longevity. The outlets cover the same core events—his heart attack, the medical advice he received, and the move toward a new track centered on wellness—while primarily framing the story through his personal perspective and post-career goals rather than offering separate new details or controversies.
