[Anticoagulants and thrombocyte aggregation inhibitors in the treatment of heart infarct. A survey].

The treatment of causes and complications of myocardial infarction is complicated by variable response to anticoagulants and inhibitors of platelet aggregation. No generally accepted principle for treatment of myocardial infarction is available at present. Following a literature review and after our own experience we suggest an immediate treatment of acute myocardial infarction with heparin and a switch to oral anticoagulants after heparin treatment of the acute phase. Three to four weeks after the acute myocardial infarction invasive diagnostic procedure should be performed. The result will lead to a decision about possibly extended therapy with oral anticoagulants. Left ventricular aneurysma e.g. would lead to prolonged coumarin-therapy. If no oral anticoagulants are necessary long term treatment with sulfinpyrazone or Aspirin plus dipyridamole should be initiated.

[Severe generalized atherosclerosis in a 14-year-old boy].

A case of severe generalized atherosclerosis in a 14-year-old boy is reported; all the large arteries, including the coronary vessels, were involved. A high degree of stenosis of the abdominal aorta very close to the origin of the renal arteries was thought to be the reason for the accompanying considerable systemic hypertension. Laboratory investigations were not able to produce evidence of the cause of the disease, and there were no apparent risk factors. Finally, it was concluded on the basis of the family history of the patient that a genetic component involving unknown pathogenetic mechanisms was responsible for the early manifestation of the disease.

Hemodynamic effects of single-dose administration of AR-L 115 BS in patients with coronary artery disease.

2-[(2-Methoxy-4-methylsulfinyl)phenyl]-1H-imidazo[4,5-b]pyridine (AR-L 115 BS) was investigated in 14 patients with coronary artery disease (CAD) and an elevated left ventricular enddiastolic pressure at rest (LVEDP). There was a significant decrease in the systolic (AOPS) and diastolic aortic pressures (AOPD) of 9% and 6%, respectively, (p less than 0.001, p less than 0.01). The LVEDP decreased by 29% (p less than 0.001), and the maximum rate of pressure rise (dp/dt max) increased by 19% (p less 0.001). The systolic (PAPS) and diastolic pulmonary artery pressures (PAPD) fell by 17% and 16%, respectively (p less than 0.05). The cardiac index (CI) increased by 12% (p less than 0.05), and the peripheral resistance (SVR) fell by 17% (p less than 0.001). Heart rate increased slightly by 5% (p less than 0.1) but this was of no clinical relevance. The right atrial pressure (RAP) and the tension time index (TTI) remained unchanged. AR-L 15 BS was observed to have vasodilating and positive inotropic effects without increasing oxygen consumption. It can therefore be recommended for use in patients with CAD and an elevated LVEDP. Side-effects have not been reported.

[High levels of CK and its isoenzymes produced by a thymus carcinoma (author's transl)].

A 63 years old female is described suffering from thymus carcinoma with increased levels of CK and CK-MB enzymes. The separation of the total CK enzymes into the isoenzymes CK-MM, CK-BB, and CK-MB showed a marked difference between the photometric and the immunological method. This discrepancy can be explained by postulating a molecule specific for thymus carcinoma, probably a new CK isoenzyme. The relevance of using the photometric method in cardiologic routine diagnostic is pointed out.

Enzyme changes after coronary angiography.

The enzymatic response to contrast media after coronary angiography was observed in 24 patients. The enzymes studied were glutamic oxaloacetic transaminase (SGOT), glutamic pyruvic transaminase (SGPT), lactic dehydrogenase (LDH), alpha-hydroxybutyrate dehydrogenase (alpha-HBDH), gamma-glutamyl transferase (gamma-GT), creatine phosphokinase (CPK), and the myocardial-specific isoenzyme of CPK (CK-MB). Angiography produced no significant elevations in SGOT, SGPT, alpha-HBDH, LDH, or CK-MB activities; gamma-GT increased up to the twelfth hour. High levels of CPK and CK-MB observed in one patient were found to be products of a thymus carcinoma. In vitro examinations also showed that concentrations of contrast media used in coronary angiography do not inhibit gamma-GT, LDH, and CPK activities.

[Coronary angiographic findings in dextrocardia (author's transl)].

This paper reports on four different types of dextrocardia in situs solitus and situs inversus. The topography of the atrial and ventricular cavities, of the great vessels and of the coronary arteries is described in detail. The value of the selective coronary arteriography in differentiation between the types of dextrocardia is discussed.

[D-transposition in situs inversus, atrial septal defect, open foramen ovale and tricuspid valve insufficiency].

This paper reports on a rare case of a so-called corrected d-transposition of the great vessels of a 62-year old woman with situs inversus. In addition the patient had a VSD, a patent foramen ovale, and a tricuspid-valve insufficiency. The topography of the ventricular cavities, the great vessels and the coronary arteries is described in detail. There is pointed to the surgical treatment of additional abnormalities to improve the prognosis.

[Complications of selective coronary angiography and the choice of contrast media].

The incidence of side effects of two contrast media containing different amounts of sodium (Urografin 76 and Conray 70) is compared in two groups of patients (totalling 133) under-going diagnostic examination by means of a cardiac catheter and selective angiocardiography. The following results were obtained: 1. Transient ischaemic reactions were observed in 4 patients of the Urografin group. Cerebral circulation was temporarily restricted in 2 patients, but there were no sequelae. One patient with a history of repeated cardiac infarction in whom the examination was the last hope with a view to coronary surgery died immediately after the angiocardiography. 2. In the Conray 70 group, ventricular fibrillation occurred 32 times in 22 patients after a total of 155 injections. Protracted asystole was observed in 2 patients. The explanation offered for the divergent findings from the use of the two contrast media is not the different anions--the iodine hosts--, but rather the difference in the amount of sodium contained in the preparations. It is concluded from the studies that contrast media which deviate to any great extent in their sodium content from the physiological range of the blood sodium concentration are unsuitable for angiocardiography.

[Changes in the acid-base equilibrium in hypokalemic patients during potassium infusions with various anions].

Based on the parameters of the acid-base status, the effect of different anions in potassium and magnesium substitution was studied. A mixture of chloride with the metabolisable anions acetate and malate does not cause any changes in the acid-base balance. The exclusive supply of metabolisable anions in the form of aspartate always results in a change of blood pH values towards an alkalosis.
