In atrial fibrillation, allapinine was shown to enhance rhythm by 7% and to increase cardiac output (p less than 0.05), as well as to slightly lower mean blood pressure and peripheral vascular resistance at rest. With exercise, both in atrial fibrillation, and sinus rhythm, there was a decrease in end-diastolic and end-systolic volumes of the left ventricle (p less than 0.05), a slight drop in ventricular ejection, that was statistically significant only with sinus rhythm (p less than 0.05). Physical exercise was not followed by an apparent additional aggravation of myocardial contractility, which makes allapinine preferable for long-term application to preserve sinus rhythm in patients without evident signs of heart failure. |
