What this trial studies

This observational study aims to evaluate the effectiveness of a therapeutic strategy to increase 24-hour systolic blood pressure in patients suffering from hypotensive syncope. It consists of two parallel substudies: one focusing on deprescribing antihypertensive medications in patients whose syncope is related to these drugs, and the other on adding fludrocortisone for patients with drug-unrelated hypotension. The study will monitor patients over a year to assess the reduction in syncope occurrences through 24-hour ambulatory blood pressure monitoring.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 with severe, recurrent reflex syncope that is resistant to lifestyle changes and education, and who have been diagnosed with hypotensive syncope.

Not a fit: Patients under 18, those with cardioinhibitory reflex syncope, or those with competing causes of syncope may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the frequency of syncope episodes in affected patients.

How similar studies have performed: While this approach is innovative, similar studies have shown promise in managing syncope through blood pressure modulation.
