Heart and skeletal muscle CK and CK-MB content was determined in 10 cases. The postoperative serum levels did not reflect differences in myocardial CK-MB content between patients. CK-MB as a percentage of total CK at peak serum CK-MB (16 +/- 1%) (mean +/- SEM) was of similar order as the percentage of CK-MB in the myocardium (papillary muscle 20.9 +/- 1.3%, right auricle 18.2 +/- 0.5%). A small proportion of CK-MB was present in all skeletal muscle samples examined (diaphragm 4.2 +/- 0.6%, rectus abdominis 0.4 +/- 0.1%), indicating that the total CK level should also be taken into account in attempts to determine the origin of a raised postoperative serum CK-MB activity. The degree of postoperative CK-MB elevation was related to the duration of operation and of aortic cross-clamping. Perioperative myocardial infarction occurred in one patient, and serum CK-MB kinetics in this patient, with a biphasic enzyme curve, differed from those in the other patients.</p>","PeriodicalId":72971,"journal":{"name":"European journal of cardiology","volume":"12 1","pages":"25-39"},"PeriodicalIF":0.0,"publicationDate":"1980-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18447387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In one, both great vessels originate from the superior right ventricle, in the other the great arteries are connected normally, the third one shows a single aortic trunc. It is concluded that the horizontal interventricular septum has to be considered as an independent cardiac deformity occurring with most types of ventriculoarterial connections. Assuming rotation of the bulboventricular loop around a base-apex-axis as the basic ontogenetic event one can trace this morphology back to its original layout. It is, therefore, possible to classify each case according to the usual nomenclature regarding the horizontal septum and the upstairs-downstairs arrangement of the ventricles as an addition. This embryological event of rotation is considered the product of a restraightening process of the previously looped cardiac tube.</p>","PeriodicalId":72971,"journal":{"name":"European journal of cardiology","volume":"11 4","pages":"269-82"},"PeriodicalIF":0.0,"publicationDate":"1980-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18398781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The 3 lamps were lit by the examiner in a stereotyped random sequence. No consequences were implied against the subjects in case of failure and this was clearly explained to them. The response time of the people was recorded together with their electrocardiogram in a one-channel recorder using a suitable circuitry. The study showed that the response time became progressively shorter during the test only in the coronary group, although the mean value did not differ significantly from that in the normal group. The R-R interval was shortened in both groups but in the coronary group significantly more so than in the normal group. Pretreatment with diazepam reversed both responses of the coronary group. Pretreatment with propranolol mitigated the tachycardiac effect of the test in the coronary group, reversed its effect in the normal group and shortened the response time significantly in the normal group. The objective time measurements by the device used might suggest that in patients with coronary artery disease both the specific (response time) and the nonspecific (R-R interval) behaviour in response to a mental stress differ from that in normal people.
