Over the past decade, understanding about feedback mechanisms involving the heart, lung and kidney is significantly improved. Each organ injury may trigger hemodynamic, neuro-hormonal and cellular pathway that may damage diverse organs. Recurrent acute on chronic injury may lead to the advanced stage of disease. On the other hand, chronic pathological conditions may decrease functional reserve leading to a high susceptibility to acute injury. Assessment of functional reserve and dosage of novel biomarkers may allow an early diagnosis and treatment. This review summarizes the current state-of-the-art understanding of cardio-pulmonary-renal interactions.
Keywords: biomarkers; cardio-pulmonary-renal interactions; functional reserve; organ cross-talk.
