AbstractThe aim of this retrospective study was to analyse the results of coronary reperfusion on the incidence and short and medium term prognosis of early primary cardiogenic shock in acute myocardial infarction. Of 339 consecutive patients admitted within 6 hours of the onset of acute myocardial infarction, 25 (7.4%) had cardiogenic shock from the onset. The majority of patients (18) underwent direct angioplasty with a successful result in 16 cases. Intravenous thrombolysis was instituted in 5 cases followed by emergency coronary angiography leading to "rescue" coronary angioplasty in 3 cases, which was successful in 2 cases. Two patients had no coronary revascularisation because of a double contra-indication to thrombolysis and catheterization by the femoral approach. Intra-aortic balloon pumping was used in 17 cases. Complementary emergency surgical revascularization was necessary in 5 patients (20%). In all, early reperfusion of the infarct-related artery was obtained in 80% of cases (20 patients). The hospital mortality was 72% (18 patients) due to refractory cardiac failure in nearly all cases. After an average follow-up of 17 months, 3 of the 7 survivors of the hospital period have died and of the 4 remaining patients, 2 are in the NYHA classes III or IV. Recent therapeutic advances have not influenced the incidence of cardiogenic shock but have significantly increased the proportion of very early cardiogenic shock, whereas the late cardiogenic shocks of more progressive onset, have nearly disappeared (4/339, 1.2% in this series). The prognosis of these early shocks, caused by severe myocardial damage, remains catastrophic and hardly improved by emergency coronary reperfusion by angioplasty and intraaortic balloon pumping.(ABSTRACT TRUNCATED AT 250 WORDS)
