Dyspnea is a subjective experience of breathing discomfort; patients experience qualitatively distinct sensations that vary in intensity. Acute dyspnea might be secondary to an acute problem, or it might be an exacerbation of an existing disease (eg, asthma, chronic obstructive pulmonary disease, heart failure). It also accompanies a variety of ...

Atrial fibrillation (AF) remains a major risk factor for stroke. Unfortunately, clinical trials have failed to demonstrate that a strategy of rhythm control--therapy to maintain normal sinus rhythm (NSR)--reduces stroke risk. The apparent lack of benefit of rhythm control likely reflects the difficulty in maintaining NSR using currently available therapies. ...
