Abstract

Clinical trials in patients with congestive heart failure have shown a wide disparity in the hemodynamic responses to chronic therapy with newer positive inotropic drugs. Therefore, the long-term efficacy of enoximone was studied in 10 patients with severe congestive heart failure. Patients were evaluated clinically, left ventricular dimensions and contractile state were assessed by echocardiography, and exercise testing was performed at basic conditions and after 1 and 8 weeks of enoximone treatment with a daily dose between 150-300 mg. Previous therapy of heart failure was continued during the study period. Clinical symptoms of eight patients were improved after 1 week and six patients showed sustained improvement after 8 weeks of enoximone treatment. The administration of enoximone increased ejection fraction by about 25% after 1 week with a similar response after 8 weeks. Five of six patients who were able to perform exercise testing initially experienced an increased exercise capacity over the study period. The enoximone regimen was continued in the responders; after 1 year, data on three patients are available and show sustained efficacy of enoximone treatment in two patients. The administration of the drug was well toler...Continue Reading

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.
