• GLORIA™-AF Registry Programme shows half of patients in China with an irregular heart beat (atrial fibrillation, or AF) suboptimally protected against potentially devastating stroke1
• Treatment guidelines recommend preventative treatment with anticoagulants over antiplatelets (such as ASA*) for AF patients at risk of stroke**2,3
• GLORIA™-AF Registry Programme will enrol up to 56,000 patients in 50 countries4

Ingelheim, Germany, 7 May, 2014 – Boehringer Ingelheim today announces first worldwide data from the GLORIA™-AF Registry Programme highlighting substantial regional differences in how patients with an irregular heart beat (atrial fibrillation, or AF) were treated with stroke prevention medicines. Data collected from nine countries over one and a half years (May 2011-January 2013) before the approval of novel oral anticoagulants4 show that a large proportion of patients with atrial fibrillation at risk of stroke were treated with antiplatelet therapy, such as ASA*, or did not receive any stroke prevention treatment at all. These patients were at increased risk of suffering a disabling or fatal stroke. The data were presented today at the World Heart Federation's World Congress of Cardiology Scientific Sessions 2014 in Melbourne, Australia.1

Patients with atrial fibrillation, the most common heart rhythm disorder worldwide, are at five-times higher risk of stroke if not appropriately treated.2,5 Blood-thinners are essential for stroke prevention in these patients.6,7 Latest treatment guidelines recommend that AF patients deemed at risk of stroke** should take warfarin or a novel oral anticoagulant (NOAC), rather than less effective antiplatelet therapies such as ASA*.2,3 Warfarin has a narrow therapeutic window and administration limitations, leading to significant underuse in some regions of the world and leaving many AF patients inadequately protected against stroke.8

The results from the first phase of the GLORIA™-AF Registry Programme were collected prior to the availability of novel oral anticoagulants in the participating countries. 1,063 newly diagnosed AF patients with a moderate to high risk of stroke were enrolled globally with results demonstrating:1

  • The majority of enrolled patients should have received stroke prevention treatment as they were deemed at moderate or high risk of stroke (CHA2DS2-VASc≥2). Despite this, 1 in 4 (25.9%) patients in China received no antithrombotic therapy compared to only 8.6% in Europe
  • Most patients in China were treated with antiplatelet therapy (53.7%) versus 27.1% in Europe
  • Use of warfarin is lowest in China and highest in Europe
  • Nearly two thirds (63.9%) of AF patients in Europe received warfarin compared to only 20.3% in China
  • Overall warfarin was most frequently prescribed for patients at high risk of stroke (36.1%, CHA2DS2-VASc≥2) versus those deemed at moderate risk of stroke (20.1%, CHA2DS2-VASc=1)

"These data show that more patients with atrial fibrillation in China were at potentially increased risk of stroke compared to Europe due to no treatment or lower usage of effective anticoagulants," said Professor Chang-Sheng Ma, Professor and Department Chair, Department of Cardiology, Beijing Anzhen Hospital, Capital Medical University, China and member of the GLORIA™-AF Steering Committee. "The ongoing publication of results from the GLORIA™-AF Registry Programme will help physicians, especially those based in China, to recognise that the gap between prescribing patterns in China compared to other parts of the world needs to be bridged. We look forward to future results which will enable us to advance management of atrial fibrillation and to ultimately better protect patients against a potentially devastating stroke wherever in the world they live."

Boehringer Ingelheim launched the GLORIA™-AF Registry Programme, the Global Registry on Long-Term Oral Antithrombotic Treatment in Patients with Atrial Fibrillation, to provide important scientific information from everyday clinical practice on antithrombotic prescribing patterns and patient outcomes. GLORIA™-AF which will enrol up to 56, 000 patients in 50 countries, is set to become one of the largest AF registries worldwide.4 Patient enrolment into the registry programme has now commenced in all major regions of the world with over 11,000 patients already participating in the registry.9

The GLORIA™-AF Registry Programme is just one part of Boehringer Ingelheim’s ongoing commitment to advancing stroke prevention in atrial fibrillation. Boehringer Ingelheim led the anticoagulant field by bringing Pradaxa® (dabigatran etexilate), the first NOAC for stroke prevention, to patients with atrial fibrillation.10 The efficacy and safety profile of Pradaxa® is well documented in the extensive RE-VOLUTION® clinical trial programme which has led to regulatory approvals in over 100 countries to date.9,11-22 Clinical experience with Pradaxa® continues to grow worldwide and currently equates to over 2.9 million patient-years in all licensed indications supporting Pradaxa® as the leading novel oral anticoagulant.9


GLORIA™-AF (Global Registry on Long-Term Oral Antithrombotic Treatment in Patients with Atrial Fibrillation)
GLORIA™-AF is a large, multinational, prospective registry programme designed to investigate patient characteristics influencing choice of antithrombotic treatment for stroke prevention in atrial fibrillation (AF). The registry will use outcome data from clinical practice to provide valuable insights on the effectiveness and safety profile of Pradaxa® versus warfarin. With up to 56,000 patients newly diagnosed with non-valvular AF at risk of stroke planned to be enrolled in up to 2,200 sites in nearly 50 countries, GLORIA™-AF will be one of the largest registries in atrial fibrillation.4

GLORIA™-AF will report patient outcome data that will assist in the evaluation of how antithrombotic therapies are used in the real world for the prevention of AF-related stroke.4 Patient enrolment into the registry programme has now commenced in all major regions of the world with over 11,000 patients already participating in the registry.9
