Summary
To delve deeper into the molecular mechanisms underlying pulmonary hypertension secondary to left heart disease (PH-LHD), an essential step toward developing a comprehensive classification, reliable biomarkers and targeted therapies. In this study, we analyzed the whole transcriptome (mRNA) of a unique cohort of patients with persistent PH due to valvular heart disease (PH-VHD) to identify biological pathways associated with disease prognosis. The analysis was performed using the well-characterized SIOVAC (Sildenafil for Improving Outcomes after Valvular Correction) clinical trial cohort. We included 116 patients with demonstrated PH-LHD after valvular correction, and 30 VHD patients with no or mild PH (Control).
