Contributing Factors to Infectious Disease Risk and Vaccine Strategy Optimization in Cardiac Surgery Patients.

Patients undergoing cardiac surgery are particularly vulnerable to infectious diseases, which may adversely affect perioperative outcomes and long-term prognosis both before and after the procedure. Moreover, those requiring heart transplantation must take immunosuppressive medications, further compromising their immunity. This narrative review aims to look for the sources of increased risk for infections as well as synthesize vaccination recommendations for these patient groups based on the available literature and guidelines. We considered the influence of age, comorbidities, length of hospitalization, procedure-related risks, and blood product transfusions on the increased risk of vaccine-preventable diseases. By comprehensively addressing these factors, healthcare providers can develop tailored vaccination strategies that maximize protection for cardiac surgical patients while minimizing potential complications and optimizing overall health outcomes.
