Heart disease in patients with osteogenesis imperfecta - A systematic review.

Introduction: Osteogenesis imperfecta (OI) is a rare, inherited systemic connective tissue disease that causes decreased bioavailability of collagen type 1. Collagen type 1 is the most abundant connective tissue in the body and a key part of many organs. While the bone phenotype in OI is well described, less is known about the effects of decreased collagen on other organs.

Anticoagulant treatment in patients with atrial fibrillation and ischemic stroke.

Background: Atrial fibrillation (AF) is the most common cardiac dysrhythmia, with a lifetime risk of 25%, and it is a well-known independent risk factor for ischemic stroke. Over the last 15 years, efforts have been made to initiate relevant treatment in patients with AF. A retrospective study was set up to clarify whether this effort has resulted in a decreased proportion of patients with known AF experiencing an ischemic stroke.
