Clinical Scorecard: Dysfunction of Microcirculation and Cardiac Protection During Cardiac Surgery with Cardiopulmonary Bypass: Mechanisms, Assessment, and Treatment Approaches

At a Glance

CategoryDetail
Condition
Key MechanismsEndothelial dysfunction, glycocalyx shedding, inflammation, oxidative stress, hemodilution, functional shunting, microthromboemboli, ischemia-reperfusion injury
Target Population
Care Setting

Key Highlights

  • CPB disrupts capillary perfusion despite normal systemic hemodynamics
  • Microcirculatory assessment tools include imaging and circulating biomarkers
  • Cardioprotective strategies aim to preserve microcirculatory function, including ischemic preconditioning and glycocalyx-preserving therapies
  • Clinical evidence for interventions remains heterogeneous and inconclusive, particularly regarding specific pharmacologic agents
  • Gaps exist in translating experimental findings to clinical practice

Guideline-Based Recommendations

Diagnosis

    Management

    • Implement cardioprotective strategies during CPB, including ischemic preconditioning and glycocalyx-preserving therapies

    Monitoring & Follow-up

      Risks

        Patient & Prescribing Data

        Pharmacologic interventions include volatile anesthetics, nitric oxide, statins, antioxidants, and antithrombotic agents, which help mitigate microcirculatory dysfunction.

        Clinical Best Practices

        • Focus on optimizing microcirculation during CPB
        • Integrate bedside imaging techniques such as orthogonal polarization spectral imaging and biomarkers with biophysiological principles
