In the past 18 months 15 patients have undergone emergency aortocoronary bypass grafts using saphenous vein in the presence of acute myocardial infarction. Eight patients were in a state of cardiogenic shock, and seven patients were having severe cardiac arrhythmias, persistent hypotension, or signs of extending infarction. There were three operative deaths, all of which occurred in the cardiogenic shock group of patients. One patient died three months after operation of a cerebrovascular accident. There are 11 surviving patients. One patient presently has angina, and one patient shows signs of left heart failure. The remaining patients are well at the present time. We feel that angiography and surgery early in the course of a complicated myocardial infarct should diminish the immediate risk of death from both pump failure and cardiac rupture. Controlled prospective studies are required to elucidate the timing and indications for operation.

Acquisition of Radial Artery Pulse is important one to enquire the human body status and condition. In this paper, we provide a system to acquire Radial Artery Pulses as in time series. These pulses are sensed by fingertip traditionally and the sensor is placed on the wrist which is strain gauge based differential mode pressure sensor (model: sm5852). The pressure exerted by Radial Artery which is minute pressure experienced by sensor converted into electrical signal which is then acquired by NI-LabVIEW 16 bit Data Acquisition card 9205 at a sampling rate of 500Hz, DAQ card having an interface with personal computer. The collected Radial Artery Pulse data are analyzed on the basis of relative amplitude of two pulses by use of NI LabVIEW software. Our application shows a probable pulse variation waveform of many subjects.
