Heart surgery patients could dramatically improve their recovery outcomes through structured preparation programs, yet most healthcare systems have failed to implement these evidence-based interventions. This gap represents a missed opportunity to reduce complications and accelerate healing in one of medicine's most demanding procedures.
Prehabilitation combines three core elements: targeted exercise training, nutritional optimization, and psychological support delivered before cardiac surgery. Unlike other surgical specialties where such programs are standard practice, cardiac surgery has lagged in adoption despite treating patients who often present with compromised fitness, frailty, and reduced physiological reserves. The timing challenge proves particularly complex, as emergency cardiac cases cannot benefit from weeks of preparation that elective patients receive.
This comprehensive review reveals a striking disconnect between biological rationale and clinical implementation. While individual components of prehabilitation show promising signals in smaller studies, robust multimodal trials remain scarce. The cardiac surgery population presents unique obstacles: patients often have severely limited exercise capacity, complex comorbidities, and urgent surgical timelines that compress preparation windows.
The field stands at a critical juncture. Large pragmatic trials currently in development will finally provide definitive evidence on whether prehabilitation programs justify their costs through improved outcomes and reduced complications. Given cardiac surgery's high stakes and substantial healthcare costs, even modest improvements in recovery could translate to significant benefits. However, successful implementation will require behavioral frameworks that motivate patient engagement across all three intervention pillars, not just clinical protocols.
