Cardiac health, type I collagen, and aging in the mouse model of osteogenesis imperfecta and a cohort of adults with OI.

Osteogenesis imperfecta (OI) is a heritable connective tissue disorder with marked skeletal fragility and increased recognition as a pleiotropic type I collagenopathy. The impact of OI-causing gene variants on cardiac health and lifespan is just beginning to be understood. To begin to investigate cardiac manifestations of OI-causing type I collagen variants, we utilized the osteogenesis imperfecta murine () model to examine survival with increased age, as well as cardiac function and collagen expression at 4 and 18 mo of age.

The management of patients on dual antiplatelet therapy undergoing orthopedic surgery.

Cardiovascular disease is prevalent in patients undergoing orthopedic surgery. Many patients who have undergone previous percutaneous coronary intervention (PCI) with stenting are on dual antiplatelet therapy in order to minimize the risk of stent thrombosis. The optimal management of these patients in the perioperative setting remains unclear.
