title: Exerimental evaluation of antianginal drugs.
abstract: A technique for testing antianginal drugs has been developed measuring hemodynamic variables, such as heart rate, left ventricular pressure and its dp/dt, aortic root and coronary sinus pressure, Veragut's index and area under the curve of LVP and metabolic variables, such as A-V difference of oxygen and lactate, oxygen content in coronary sinus, percentage extraction of oxygen, excess lactate. Physiological experimental conditions included spontaneously breathing dogs, catheters introduced under X-rays control and closed chest. A commentary about activity criteria, usefulness and inconvenients of this technique is presented.
