Sex-specific Genetic Determinants of Right Ventricular Structure and Function.

Rationale: While sex differences in right heart phenotypes have been observed, the molecular drivers remain unknown.

Objectives: To provide biological insights into sex differences in the structure and function of the right ventricle (RV) using common genetic variation.

Methods: RV phenotypes were obtained from cardiac magnetic resonance imaging in 18,156 women and 16,171 men from the UK Biobank.

Residual risk identified in routine noninvasive follow-up assessments in pulmonary arterial hypertension.

Background: The 2022 ESC/ERS guidelines on pulmonary hypertension recommend noninvasive risk assessments based on three clinical variables during follow-up in patients with pulmonary arterial hypertension (PAH). We set out to test whether residual risk can be captured from routinely measured noninvasive clinical variables during follow-up in PAH.

Methods: We retrospectively studied 298 incident PAH patients from a German pulmonary hypertension centre who underwent routine noninvasive follow-up assessments including exercise testing, echocardiography, electrocardiography, pulmonary function testing and biochemistry.
