from what i understand, nitroglycerin is a strong venodilator, not as much as a arterial vasodilator. It wouldn’t be as strong as something like dipyramidole which is used for pharmacologic stress testing. AMBOSS says “Administration of vasodilators (e.g., dipyridamole) → coronary vasodilation → decreased hydrostatic pressure in the normal coronary arteries → blood shunting back to well-perfused myocardium → decreased flow to the ischemic myocardium → myocardial ischemia downstream to the pathologically dilated vessels → angina pectoris and/or ECG changes”
