Relationship Between Right Ventricular Function and Chronotropic Incompetence in Pulmonary Arterial Hypertension Associated With Connective Tissue Disease
Background Pulmonary arterial hypertension associated with connective tissue disease (CTD-PAH) is a progressive disease characterized by remodeling of the pulmonary vasculature, leading to increased right ventricular (RV) afterload and impaired exercise capacity. Research Question The impact of RV dysfunction on chrono...
