Effects of benzonal on intracardiac hemodynamics in experimental myocardial infarct

: Benzonal was tested for effects on the natural history of experimental myocardial infarction. Systemic and intracardiac hemodynamic parameters were studied in 35 Shinshilla rabbits. Benzonal was found to exert a positive action of myocardial diastolic relaxation and to be beneficial on the natural history of experimental myocardial infarction.
