Mitral Stenosis
Effect of Ivabradine on Heart Rate & Effort Tolerance in Mitral Stenosis in Sinus Rhythm
The purpose of this study is to study the effect of Ivabradine vs Atenolol on heart rate and effort tolerance in patients with mild to moderate mitral stenosis and normal sinus rhythm.

Heart Rhythm Disorder
Role of Ivabradine for Heart Rate Control in Management of Patients With Sepsis and Septic Shock
Tachycardia is associated with excess mortality during septic shock. This may be related to the increase in cardiac metabolic demand, impaired cardiac diastolic function and less effect of administered exogenous catecholamines.
- Trial name
- NCT06742164
- Testing
- Ivabradine 5mg Tab, control
- Volunteers
- 76 people

Persistent Atrial Fibrillation
Comparison of Brain Perfusion in Rhythm Control and Rate Control of Persistent Atrial Fibrillation
Atrial fibrillation (AF) is associated with impaired cognitive function (CogF) and/or dementia, but it is unclear whether rhythm control of AF improves CogF or brain perfusion.
