Emergency coronary bypass for cardiogenic shock has been associated with a high operative mortality. From February 1986 through October 1989, 40 patients with acute myocardial infarction were operated. Ten pts (25%) were in shock despite intensive treatment (intra-aortic balloon pump in 4, catecholamines in 10). ⋯ One pt is in group IV (transplant candidate). Myocardial infarction complicated by cardiogenic shock can produce a mortality rate in excess of 85%. Contemporary medical management has had little effect on mortality, hence effective surgical therapy has evolved for this lesion.

Comparative Study
[Measurement of arterial blood pressure using the sphygmomanometer-S and the direct method].
Sphygmomanometer--S is the microcomputer device measuring blood pressure (BP) by the noninvasive sphygmooscillographic method following standard algorithm. When compared sphygmomanometer--S with auscultatory method, this device overestimated systolic BP by 7 mm Hg, and underestimated diastolic BP by 9 mm Hg on the average. In other words, sphygmomanometer--S overestimated systolic pressure and lowers diastolic pressure in relation to auscultatory method in the same ratio and value, as the direct method in relation to the auscultatory method. ⋯ The correlation coefficient (r) was 0.97 for systolic, 0.90 for diastolic and 0.92 for mean pressure. Systolic and diastolic pressure measured by the sphygmomanometer--S were 2 mm Hg and mean 0.6 mm Hg higher on the average, than the same pressures obtained by direct method (ryc. 1). These differences were statistically not significant.(ABSTRACT TRUNCATED AT 250 WORDS)
