{"title":"[Accurate diagnosis of temporary myocardial ischemia by noninvasive regional wall motion analysis].","authors":"Y Sugishita","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Exercise ECG testing is the most popular method clinically detecting temporary myocardial ischemia, but both false-positive and false-negative results are reported. Detection of regional myocardial dysfunction during exercise using radionuclide angiocardiography or echocardiography has recently been developed to detect temporary myocardial ischemia in patients with coronary artery disease. In patients having chest pain and ECG changes during exercise, most of whom have coronary stenosis arteriographically, exercise radionuclide angiocardiography revealed an increased number of abnormal regional motion walls, an aggravation of asynergy by point scoring system, and a decrease of left ventricular ejection fraction (EF). In most of patients without coronary stenosis, on the other hand, no asynergy with increase of EF was observed. For detecting temporary myocardial ischemia, abnormal exercise radionuclide angiocardiography seemed rather sensitive than exercise 201-T1 myocardial imaging abnormality. During exercise, the regional wall motion abnormality was detected earlier by echocardiography than by electrical abnormality. In the cases, in which ST segment elevated during exercise, EF measured by radionuclide angiocardiography decreased remarkably, suggesting severe myocardial ischemia. In many of those, however, T waves were negative at rest and became positive during exercise, and EF increased, suggesting the other mechanism than myocardial ischemia. The success rate of exercise radionuclide angiocardiography was high. This method was useful not only in localizing abnormal wall motion but in obtaining reliable EF, though it is such an expensive device that it can be set only in the limited institutions. A major difficulty with standard M-mode echocardiography is in its \"ice-pick\" view, which may be compensated by 2-dimensional technique. Echocardiography can be used to detect the time course of the influence of myocardial ischemia. For evaluating temporary myocardial ischemia, examinations of regional wall motion abnormality is useful, because of high specificity, high sensitivity, localizing and grading the ischemia, and new interpretation of the findings of other examinations such as exercise ECG.</p>","PeriodicalId":77861,"journal":{"name":"Journal of cardiography.

The subjects were 21 patients with ischemic heart disease associated with left ventricular failure. Fourteen patients received venodilators alone (Group I), and seven were administrated venoarterial dilators alone (Group II). At the time of the maximum effect, the two groups showed similar improvement. In Group I, the left ventricular filling pressure (LVFP) was reduced from 24 to 16 mmHg and the cardiac index (CI) was increased from 2.5 to 2.8 l/min/m2. In Group II, the LVFP was similarily reduced from 27 to 16 and the CI increased from 2.4 to 2.9. The effects of each drug on the total vascular resistance/LVEP were similar in both groups. In animals with partial occlusion of the left anterior descending artery, intravenous administration of nitroglycerin (TNG) or nitroprusside (NPS) lowered the aortic pressure stepwise at intervals of 10 mmHg from a mean of 130 mmHg. As a result, segmental shortening was improved either by TNG or NPS. However, when the systolic aortic pressure was decreased below 100 mmHg, segmental shortening of the ischemic area was aggravated in dogs receiving either drug. The end-diastolic length showed no difference between the dogs administrated TNG and NPS. When the effects of TNG and nifedipine (NFP) were compared to those in dogs with the old infarcted myocardium, both drugs produced improvement in hypokinetic segments. TNG induced a decrease in the end-diastolic length, whereas NFP revealed no changes, reflecting different modes of improvement.(ABSTRACT TRUNCATED AT 250 WORDS)</p>","PeriodicalId":77861,"journal":{"name":"Journal of cardiography.

Computer analysis of two-dimensional echocardiograms for quantitative evaluations of the left ventricular regional contractility in myocardial infarction: A new practical method for computer digital image processing of two-dimensional echocardiograms was developed for quantitating left ventricular regional contractility. Short-axis cross-sectional images of the left ventricle at the levels of the mitral valve (MV), papillary muscles (PM) and the apex (AP) were recorded using a phased array sector scanner in thirty patients with healed myocardial infarction and fifteen normal control subjects. The echocardiographic data were recorded on the video tape and transferred to a minicomputer via interface circuits, digitized, and processed automatically. Each digitized image consisted of 256 X 256 pixels with a gray scale of 256 values. The edges of the endocardial and epicardial walls were detected by applying sequential steps including smoothing, dynamic thresholding, region growing, and filling of small holes. The rationale of edge detection depended on assuming that abrupt changes in gray levels occurred at the boundary, and that the points with maximum gradient values were boundaries of the left ventricular wall. Best-fit contours of endocardial and epicardial edges were drawn by fitting a spline. Besides this automatic edge tracing, endocardial and epicardial edges were also manually traced using a digi-pen system, whose results coincided well with automatic tracings. After detection of edges of endocardial and epicardial walls, the short-axis cross sectional left ventricular wall at each level was divided into eight segments. The geometric center of the end-diastolic left ventricular cavity and the axis connecting this with the posterior end of the right side of the septum was used as the reference point and line (fixed reference system). End-diastolic and end-systolic segmental hemiaxes, segmental area, segmental wall thickness and changes during the cardiac cycle were measured and calculated automatically in each segment using a computer. Regional contractility of the left ventricle was evaluated by percent systolic changes of the segmental hemiaxis, area and wall thickness. These values were significantly reduced in the infarcted left ventricular wall as defined by left ventriculography and coronary angiography.(ABSTRACT TRUNCATED AT 400 WORDS)</p>","PeriodicalId":77861,"journal":{"name":"Journal of cardiography.

Biplane left coronary cineangiography were performed for 19 normal subjects, eight patients with old anteroseptal infarction and seven patients with hypertrophic cardiomyopathy. The coordinates of the points on the left coronary artery were measured, and the spatial distances (segment length) between any of those two points were calculated. The maximum value of the segment length (Lmax), the minimum value (Lmin), the value at the R wave of the electrocardiogram (LECG R) and that at the end of systole (LES) were calculated. We calculated the total shortening rate as (Lmax--Lmin)/Lmax X 100 and systolic shortening rate as (LECG R--LES)/LECG R X 100. In normal subjects, the total shortening rate was 10.1 +/- 2.7 (SD) at the anterior interventricular septum; 11.8 +/- 3.3 at the interior interventricular septum; and 13.4 +/- 4.5 at the free wall, and 7.9 +/- 4.2% at the atrioventricular groove.
