Mental stress-induced myocardial ischemia is a frequent phenomenon in patients with coronary artery disease. Women with coronary artery disease tend to have more mental stress-induced myocardial ischemia and more chest pain/anginal symptoms than men, but whether the association between mental stress-induced myocardial ischemia and angina burden differs in women and men is unknown. ⋯ In women, but not in men, anginal symptoms may be a marker of vulnerability toward ischemia induced by psychologic stress. These results highlight the psychosocial origins of angina in women and may have important implications for the management and prognosis of women with angina.

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.

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.
