Examining how biological sex affects heart function in CTEPH patients

Biological Sex and Sex Hormones Moderate Right Ventricular (RV) Dysfunction and Recovery in Chronic Thromboembolic Pulmonary Hypertension

Observational Intermountain Health Care, Inc. · NCT06105242

This study looks at how being male or female affects heart function in people with chronic thromboembolic pulmonary hypertension (CTEPH) to see if there are any differences in their recovery after surgery.

What this trial studies

This observational study aims to identify differences in right ventricular (RV) function between biological sexes in patients diagnosed with chronic thromboembolic pulmonary hypertension (CTEPH). It will analyze historical data from patients who have undergone right heart catheterization and echocardiography to assess RV function at diagnosis and after pulmonary thromboendarterectomy (PTE) surgery. The study will also explore the relationship between sex hormone levels and RV function during diagnosis and recovery. The methodology includes TTE strain analysis to compare RV function across sexes.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older diagnosed with CTEPH who have undergone the necessary diagnostic procedures.

Not a fit: Patients with unclear or mixed pulmonary hypertension diagnoses, those under 18, or pregnant individuals may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and treatment strategies for CTEPH based on biological sex differences.

How similar studies have performed: While studies examining sex differences in cardiovascular conditions exist, this specific focus on CTEPH and RV function recovery is relatively novel.
