“…Circulatory support devices include the use of prosthetic ventricles (390-392), the LV turbine (Hemopump) (393)(394)(395), and percutaneous cardiopulmonary bypass circuits (396). Each has been used in patients with cardiogenic shock after AMI with improvement in other organ perfusion, in many cases as a bridge to definitive revascularization or cardiac transplantation.…”

It is the aim of these revised guidelines to reflect what the committee has identified as the most important changes to be made in thinking about patients with AMI. Many therapies and procedures in current use are not based on sound scientific evidence. The committee proposes the abandonment of such therapies and procedures that can be identified with confidence. On the other hand, new information suggests that a practical division of all patients with AMI is to classify them as those with ST-segment elevation and those without it. Evidence now shows a distinction in pathoanatomy between the two that demands different therapeutic approaches. Ample evidence exists that persons with suspected MI and ST-segment elevation or bundlebranch block (BBB) should undergo immediate reperfusion, and those without these findings should not. Committee members were selected from cardiovascular specialists with broad geographical representation and combined involvement in academic medicine and primary practice. The Committee on Management of Acute Myocardial Infarction was also broadened by members of the American Academy of Family Physicians, the American College of Emergency Physicians, the AHA Council on Cardiovascular Nursing, and the American Association of Critical-Care Nurses.

“…Continuous nonpulsatile flow occurring throughout the cardiac cycle independent of cardiac rhythm augments coronary perfusion and im proves collateral blood flow into the ischemic region [11]. Although significant hemodynamic improvement was re ported during Hemopump assistance in patients with car diogenic shock, the large size of the device prevented sur gical insertion via the iliofemoral system in 23% of patients [60], A newly designed 14-french Hemopump capable of delivering 1.5-2.2 1/min permits percutaneous transfemoral insertion and has recently been used success fully for supported high-risk angioplasty. One patient remained conscious with a mean aortic pressure of 50 mm Hg during Hemopump assistance, despite ventricular fibrillation that followed balloon inflation [61].…”

Myocardial necrosis progresses with the duration of coronary occlusion in the early stages of acute myocardial infarction. Prompt recanalization of the infarct-related artery resulting in effective and sustained reperfusion of jeopardized myocardium is the goal of modern therapy. Clinical thrombolysis trials have demonstrated a significant survival advantage for treated patients, but only a modest recovery of global or regional systolic left ventricular function. Accelerated regimens of administering currently available thrombolytic agents are associated with early coronary patency rates approaching 85%, although effective coronary perfusion is restored in only slightly better than one half of patients treated. Primary angioplasty without antecedent thrombolytic therapy has resulted in high patency rates with superior coronary flow when performed in some experienced centers. Treatment of cardiogenic shock requires immediate mechanical or surgical intervention to reestablish coronary perfusion often following placement of a circulatory assistance device. Future trends toward very early initiation of thrombolytic therapy, improvements in adjunctive therapy and advances in the noninvasive detection of recanalization should permit selective use of aggressive interventional therapy for failed thrombolysis in a minority of patients with acute myocardial infarction.
