Although sudden cardiac death is a leading cause of death in the United States, most victims of sudden cardiac death are not identified as at risk prior to death. We sought to derive and validate a population-based risk score that predicts sudden cardiac death. ⋯ The proposed risk scores may be used to identify those at risk for sudden cardiac death within 10 years and particularly classify those at highest risk who may merit further screening.

Patent foramen ovale closure represents a potential secondary prevention strategy for cryptogenic stroke, but available trials have varied by size, device studied, and follow-up. ⋯ In patients with recent cryptogenic stroke, patent foramen ovale closure reduces recurrent stroke/transient ischemic attack compared with medical therapy, but is associated with a higher risk of new-onset atrial fibrillation/flutter.

Most patients with asthma are managed by primary care providers. Severe asthma is associated with substantial morbidity and health care resource use, and long-term sequelae of severe asthma include airway remodeling and a greater risk of developing chronic obstructive pulmonary disease. These consequences highlight the importance of early identification and improved management of patients with severe asthma. ⋯ An increased understanding of asthma pathophysiology and its relationship to disease activity has identified therapeutic targets and associated biomarkers. Biologic therapies directed at these targets offer individualized targeted treatment of severe asthma. We review evidence-based guidelines for identification and management of severe asthma, clarify the relationship of asthma control and asthma severity, and provide an overview of new biologic therapies offering additional treatment options for patients with severe asthma.
