Power Failure in Acute Myocardial Infarction

摘要: PROMPT ALTERATION in the cause of death secondary to acute myocardial infarction was recognized several years ago with advent coronary care units. Arrhythmic deaths unit have become rare, and power failure heart has emerged as major (Fig. 1). The survival rate for individuals who develop shock syndrome associated is less than 15 per cent most reported series, remained essentially unchanged 90 years. Our current understanding pathophysiology all forms remarkably incomplete. Furthermore, postmortem findings such patients discourage hopes development successful medical treatment; area necrotic left ventricular mass dying seldom 40 entire ventric1e.l It conceivable, nevertheless, that a considerable impact on mortality from may be seen next few Before advances can made, it will necessary to: (1) define structural derangements at onset failure, rather hours or days later after interventions prolonged hypotension; (2) prognostic indices, either data time admission hospital collected serially. These indicators allow identification high-risk recognition apparently compensated before irreversible changes ensued. first systematic reports begun appear past year; (3) On basis initiate support circulation an earlier point course illness-perhaps within one hour hospital. This review restricted consideration ( 1) microscopic macroscopic failure; relation these alterations physical examination hemodynamic findings; antecedent evaluation risk mortality; (4) unresolved issues effectiveness therapy; (5) application new technologic advances.
