This report discusses experimental and clinical applications of positron emission tomography to the heart, including measurements of blood flow to the myocardium and studies of metabolism and experimental injury. Most initial clinical studies have concentrated on ischemic heart disease, but the technique also has potential for investigation of cardiomyopathies, studying ...

BACKGROUND: Cardiotrophin-1 (CT-1) is a potent hypertrophic factor discovered by coupling expression cloning in a mouse embryonic stem cell-based model of cardiogenesis. METHODS AND RESULTS: The present study was designed to investigate the potential activation of atrial and ventricular CT-1 expression in pacing-induced experimental congestive heart failure (CHF) and its ...

Various cardiovascular effects of a new synthetic coronary vasodilator, alpha-isopropyl-alpha [(N-methyl - N - homoveratryl)-gamma-amino-propyl]-3, 4-dimethoxyphenylacetonitrile HCI (D365, Iproveratril or Isoptin) have been studied. In isolated perfused rabbit hearts the drug exerts a potent coronary vasodilator action, but can depress myocardial contractions and A-V conduction. In anesthetized cats it produces ...

Synthetic oxytocin (Syntocinon) can be shown to reduce or abolish ST-T changes induced experimentally by hypoxaemia alone, by hypoxaemia and ergometrine, by vasopressin, and by a new procedure involving injection of small doses of picrotoxin into the lateral cerebral ventricle. Ventricular fibrillation induced by picrotoxin can also be reversed by ...

Marked obesity was induced in rats by feeding a high fat, egg yolk-rich diet. The obese rats were hyperlipemic and showed an increased incidence of lipomatous coronary lesions, but did not develop severe atheromatous lesions. Spontaneous vascular lesions of several kinds have been observed in aging rats. Among them, plaques ...

Focal myocardial necrosis that was often extensive was found in a high percentage of rabbits, guinea pigs, and mice given a single intravenous injection of crystalline streptococcal proteinase. The findings are discussed in relation to their possible implications for the pathogenesis of the cardiac lesions of rheumatic fever.

An experimental study upon the demonstrable effects of large doses of dried thyroid gland and thyroxin upon the myocardium of rabbits has been made. Animals under such treatment show characteristic clinical symptoms with definite, although relatively slight, myocardial lesions. Similarly treated animals which have, in addition, been subjected to chloroform ...
