Minimally Invasive Heart Procedure Outperforms Medication for Advanced Atrial Fibrillation in Major International Trial

A major international clinical trial led by University of British Columbia researchers has found that a minimally invasive heart procedure may be superior to medication as a first-line treatment for people with advanced atrial fibrillation. The condition affects more than 50 million people worldwide, including about one million Canadians, causing irregular heartbeats that lead to symptoms like fatigue, shortness of breath, and palpitations. Atrial fibrillation significantly increases the risk of stroke, heart failure, and early death, making effective treatment critical. The trial results suggest that the minimally invasive procedure offers improved outcomes compared to traditional medication approaches for patients with this common and serious heart rhythm disorder.

Clinical trial findings on catheter ablation versus medication

• ▪Researchers at the University of British Columbia led a major international clinical trial on atrial fibrillation treatment.
• ▪A major international clinical trial led by researchers at the University of British Columbia found that a minimally invasive heart procedure may be a better first-line treatment than medication for people living with advanced forms of atrial fibrillation.

Atrial fibrillation prevalence and health impacts

• ▪Atrial fibrillation causes the heart to beat irregularly.
• ▪Atrial fibrillation is a common and serious heart rhythm disorder that affects more than 50 million people worldwide.
• ▪Atrial fibrillation affects about one million Canadians.
• ▪Atrial fibrillation significantly increases the risk of stroke, heart failure and early death.
• ▪Atrial fibrillation can lead to symptoms like fatigue, shortness of breath and palpitations.

Perspective of University of British Columbia researchers

• ▪The minimally invasive heart procedure offers improved outcomes for patients with advanced atrial fibrillation compared to medication.
• ▪The minimally invasive heart procedure should be considered as a first-line treatment rather than medication for advanced forms of atrial fibrillation.
