Thirty-four patients with coronary heart disease who had silent myocardiac ischemic episodes as evidenced by long-term ECG monitoring were examined. Silent ST-segment elevations and depressions were encountered 2.7- and 4.9-fold as compared to manifest ones. The fact that the CHD patients had silent ST-segment depressions and/or prolonged high-amplitude silent ST-segment elevations suggests a grave severity of abnormal myocardial processes. There was a reduction in the number, duration of silent ST-segment elevations and depression episodes and in the amplitude of silent ST-segment depressions. This may indirectly indicate that the agent affects predominantly coronary blood flow and coronary vascular tone. 相似文献

Left-ventricular myocardial contractility was assessed in thrombolytically-treated patients with acute myocardial infarction. General and local left-ventricular activity was shown to deteriorate progressively in patients with "late" or altogether absent recovery of coronary flow, whereas patients with early recovery of coronary flow demonstrated intact general contractility parameters and better contractility in the affected area. Coronary reperfusion within 5-6 hours helps to maintain functional capacity, which is less marked than the one in patients with early reperfusion. 相似文献

T cell and lymphocyte subpopulation counts measured by surface markers (T helpers and T suppressors), lymphocyte blast transformation with FHA, IgA, IgM and IgG levels and phagocytosis were evaluated in 45 patients with circulatory insufficiency (CI), including 30 with coronary heart disease (CHD) and 15 with dilatation cardiomyopathy (DCMP). Three patterns of immunologic response were identified: the first one (intact immunity) was found in normal subjects, coronary patients without CI and those with first-stage CI; the second pattern (immune dysfunction) was detected in coronary patients with CI, stage 2A and DCMP patients with CI, stage 2B; the third pattern (immune deficiency) was present in coronary and DCMP patients with CI, stage 2B-3. The extent of immunologic reactivity disturbance is shown to depend on the severity of CI. DCMP was associated with a deficiency of T suppressors that may be useful as an additional diagnostic sign of this condition. 相似文献
