Intraaortic balloon pumping prevented ischemia in 9 of 11 patients (81.8%) and reduced ischemic attacks in 2 patients with recurrent angina resistant to medical therapy.

Does intraaortic balloon pumping reduce ischemic attacks in patients with medically refractory recurrent angina at rest?
Intraaortic balloon pumping effectively controls myocardial ischemia resistant to medical therapy, facilitating safe subsequent coronary angiography and bypass surgery.
Eleven patients were studied because of recurrent angina at rest. In five cases ischemic pain developed 3-10 days after acute myocardial infarction. Pain recurred in all cases despite therapy with bedrest, oxygen, heparin anticoagulation, nitrates, and whenever possible, beta blockade. Intraaortic balloon pumping with a 30-cc balloon prevented ischemia in nine patients and markedly reduced the frequency of ischemic attacks in two. Coronary angiograms were obtained during circulatory assistance without complication and confirmed proximal coronary artery obstructions in all patients. Saphenous vein aortocoronary bypass grafting was then performed. Intraaortic balloon pumping will effectively control myocardial ischemia resistant to medical therapy.
Gold et al. (1973) conducted an observational in Recurrent myocardial ischemia (n=11). Intraaortic balloon pumping was evaluated on Prevention of ischemia. Intraaortic balloon pumping prevented ischemia in 9 of 11 patients (81.8%) and reduced ischemic attacks in 2 patients with recurrent angina resistant to medical therapy.
