Carvedilol prospective randomized cumulative survival (COPERNICUS) trial: carvedilol as the sun and center of the beta-blocker world?

Heart failure is a deadly disease that has reached epidemic proportions in industrialized countries. Patients living with heart failure carry a heavy burden in terms of morbidity. Many patients require repeated hospitalizations for cardiovascular problems, especially for episodes of worsening heart failure. In fact, heart failure is one of the most important causes of hospital admissions in the United States, accounting for over 2.5 million admissions per year. Once hospitalized, patients with heart failure have an increased risk of recurrent hospitalizations and death. Approximately 30% to 40% of patients are readmitted within 6 months of an index hospitalization. Angiotensin-converting enzyme (ACE) inhibitors, digitalis, and spironolactone decrease the risk of hospitalization in heart failure patients; however, the annual rate of hospital admission for worsening heart failure has remained high.1–3
