Exploring the Inflammation-Related Mechanism of Lingguizhugan Decoction on Right Ventricular Remodeling secondary to Pulmonary Arterial Hypertension based on Integrated Strategy using UPLC-HRMS, Systems Biology Approach, and Experimental Validation

Pulmonary arterial hypertension (PAH) and the consequent right heart dysfunction persist with high morbidity and mortality, and the mechanisms and pharmacologic interventions for chronic right-sided heart failure (RHF) have not been adequately investigated. Research has shown that prolonged inflammation is critical in precipitating the progression of PAH-associated right heart pathology. Some research demonstrated that Lingguizhugan decoction (LGZGD), as a classical Chinese medicine formula, had beneficial effects in alleviating PAH and RHF, while its underlying mechanisms involved are not fully elucidated.
