“…The prevalence of contraction abnormalities in patients with CAD was quite similar (65%) to previous reports (Alijarde et al, 1982;Bartel et a/., 1974;Miller et al, 1974;Rijneke et al, 1980;Vieweg et a[., 1980). False negative tests in patients with past MI were most often seen with akinetic or dyskinetic (55%) left ventricular contraction.…”

Summary:The results of exercise electrocardiography were studied in a random sample of 317 subjects with clinical suspicion of coronary artery disease. In 278 patients with coronary artery disease the rate of false negative tests was 18% with and 12% without previous myocardial infarction. If ST elevation was considered a negative response, the corresponding values were 25% and 13%, respectively, p

“…Miller et al (1974) examined the biplane left ventriculograms (RAO 30°and LAO 60°) of 123 consecutive patients with arteriographically proven coronary arterial stenosis for abnormalities of left ventricular segment contraction. They observed that the 300 right anterior oblique view was adequate for detecting a disorder in contraction pattern except in thepatients withposteriorinfarction.…”

“…The first possibility is that the asynergy in patients with inferior myocardial infarction is less extensive than in patients with anterior infarction even with the same infarct size. Miller et al (1974) assessed the asynergy by biplane left ventriculography in 49 patients with myocardial infarction and observed that dyskinesis was more frequent in the patients with anterior infarction than in those with inferior infarction, while hypokinesis was more frequent in inferior infarction than in anterior infarction. In our series, only 2 of 18 patients with anterior infarction had hypokinesis, while 2 of 16 patients (12-5 %) with inferior infarction had a normal contraction patternand8patients (50%) hadhypokinesis.…”

SUMMARY In order to investigate the relation between infarct size in acute myocardial infarction and left ventricular ejection fraction early after recovery, total creatine kinase released was calculated by the modified method of Sobel et al. (1972) from the serial determinations of serum CK activity; left ventriculography and selective coronary arteriography were performed at a mean of 2 months after the onset of infarction in 34 patients with acute myocardial infarction. Of 34 patients, 32 (94%) had left ventricular asynergy. In 21 patients with akinesis and/or dyskinesis, a significant correlation was found between the extent of thenon-contractingsegmentof theleft ventricle and left ventricular ejection fraction, indicating that the extent of the non-contracting segment contributes largely to reduction of ejection fraction in patients with myocardial infarction.A close inverse correlationwas also observed between theinfarct size and ejection fraction after anterior and after inferior infarction, though cardiac index was maintained over 2-0 1/min per m2 in all except 3 patients. The ejection fraction in patients with anterior myocardial infarction was lower than in those patients with inferior myocardial infarction with comparable values of total CK released. This was true even after exclusion of 6 patients with proximal right coronary artery lesions who might have had right ventricular necrosis as well as left, indicating that left ventricular function after infarction depends in part on the site of the infarct.Since Harrison (1965) In the present study, we attempted to estimate infarct size by calculating the total CK released from infarcted myocardium using the method of Sobel et al. (1972)

“…These changes are related to localized wall motion (Miller et al, 1974;Williams et al, 1973), ventricular function (Askenasi et al, 1976), and less directly, to mortality (Awan er al., 1977). We have shown in this study that ECG recovery after acute myocardial infarction continues for 1 year.…”

Summary: The recovery of the ECG signs of anterior myocardial infarction has been studied in 70 patients. A significant increase in R-wave amplitude and decrease in Q-wave amplitude on 24-lead precordial mapping was observed during one year after infarction. Patients with lower initial heart rate showed a greater recovery of Rand Q-wave amplitudes, as did patients with smaller infarcts, as assessed by peak heat-stable lactate dehydrogenase (LDH).
