Hypoxia-Induced BACH1 Elevation Drives Pulmonary Hypertension via Activation of TGFBR2/SMAD Signaling

By MedXY 07/15/2026

BACH1 stabilization under hypoxia promotes pulmonary hypertension by enhancing TGFBR2/SMAD pathway activity in pulmonary artery smooth muscle cells, suggesting BACH1 as a promising therapeutic target for PH.

Impact of Short-Term High-Altitude Exposure on Right Ventricular Load and Oxygen Delivery in Pulmonary Vascular Disease Patients

By MedXY 07/05/2026

A two-day stay at 2500 m altitude increases right ventricular afterload and impairs ventricular-arterial coupling but maintains oxygen delivery in stable pulmonary vascular disease patients.

CT Small-Artery Loss Tracks Severe Pulmonary Hypertension in COPD and Fibrosing ILD More Closely Than Parenchymal Damage

By MedXY 06/02/2026

CT-derived pulmonary vascular metrics, especially the small-artery to total arterial volume ratio, identify severe pulmonary hypertension in chronic lung disease, with distinct vascular remodeling patterns in COPD and fibrosing ILD.

Dual versus monotherapy pretreatment before balloon pulmonary angioplasty in CTEPH: effects on complications and outcomes

By MedXY 05/18/2026

In CTEPH patients undergoing balloon pulmonary angioplasty, dual pulmonary hypertension-targeted pretreatment was linked to fewer thoracic complications and better 6-month clinical improvement than monotherapy.

The BMPR2 Nexus: How Breast Cancer Acts as a Second Hit for Pulmonary Hypertension

By MedXY 03/01/2026

Emerging evidence identifies a bidirectional link between breast cancer and pulmonary arterial hypertension (PAH) driven by BMPR2 signaling and IL-1β-mediated inflammation. This study suggests breast cancer may serve as a critical second hit, unmasking latent vascular susceptibility in at-risk populations.
