Hemodynamic effects of acute digitalization several months after acute myocardial infarction.
Left ventricular function was investigated at rest and during exercise by heart catheterization in 15 patients 3-5 months after acute myocardial infarction. The effect of 1 mg digoxin i.v. in ten patients was correlated to placebo (saline solution) in five patients. A significant decrease of the left ventricular enddiastolic pressure, increase of left ventricular systolic ejection fraction and a shift of the left ventricular function curve to left upwards was found after digoxin with no changes in the placebo group. This beneficial effect of acute digitalization in patients convalescing from uncomplicated myocardial infarction without clinical signs of manifest heart failure could have therapeutic implication.
