Emphasizing Heart-Lung Interactions in Pulmonary Vascular Disease: A Call for Advanced Research

A recent editorial published in Comprehensive Physiology highlights the critical need for a deeper understanding of the complex interactions between the heart and lungs in pulmonary vascular disease (PVD). Led by Dr. Tim Lahm of National Jewish Health, the article emphasizes that pulmonary hypertension is not solely a lung disorder but involves systemic processes affecting multiple organs, necessitating a broader research focus. The authors advocate for investigating how the right atrium and right ventricle respond to pressures in the pulmonary circulation, revealing that dysfunction in these heart components can exacerbate pulmonary and systemic pathologies.

The editorial underscores that the heart and lungs operate as a tightly interconnected unit—sometimes referred to as the 'right atrium–right ventricle–lung vascular unit.' Disruptions in one can significantly impact the other, with repercussions extending to the kidneys, liver, brain, and skeletal muscles. This systemic view challenges traditional lungs-centric perspectives and calls for novel research strategies that include molecular mediators, mechanical stress pathways, and cutting-edge models like organ-on-a-chip and computational simulations.

Furthermore, the authors extend an invitation for submissions of basic, translational, and clinical research papers exploring these cardiopulmonary interactions. They emphasize studying sex and age differences, disease phenotypes, and innovative diagnostics and treatments.

This editorial advocates for a paradigm shift towards understanding pulmonary hypertension and PVD as systemic diseases, urging the scientific community to expand its investigative horizons. Unlocking these complex cardiopulmonary dynamics holds promise for advancing patient care, improving outcomes, and developing personalized therapeutic strategies.
