A case of acute myocardial infarction (AMI) following accidental iatrogenic overdose by adrenaline injection is described in a male aged 55 years. This patient was given 1 mg of adrenaline due to anaphylactic symptoms. Afterwards he presented with angina pectoris, dyspnoea and ST-segment elevation
Lycopene, a carotenoid rich in tomato fruit (ripe), is an effective antioxidant and free radical scavenger. In this study n-hexane extract of tomato was evaluated for its protective action against oxidative stress in experimental myocardial infarction induced by administration of adrenaline in rats.
Plasma adrenaline (A) and noradrenaline concentrations (NA) were determined in 41 patients admitted to the coronary care unit (CCU). Eleven with suspected acute myocardial infarction (AMI), subsequently excluded as a diagnosis, had significantly elevated A and NA compared with 20 normal resting
The catecholamine (CA) response to upright posture was studied in 30 brainstem infarct patients with orthostatic arterial hypotension; the investigation was made before and after 10 days propranolol therapy (in 15 cases) and before and after 10 days metoclopramide therapy (in other 15 cases). Before
It is known that in most cases of transmural acute myocardial infarction a platelet clot originates within a coronary artery. In acute myocardial infarction patients increased levels of the plasma catecholamines adrenaline and noradrenaline as well as the platelet release proteins platelet factor 4
STUDY OBJECTIVE - The objective was to measure platelet function in vivo (as cutaneous bleeding time), the role of catecholamines, and the effect of inhibiting thromboxane synthesis on bleeding time, in patients with myocardial infarction, unstable angina, and non-cardiac chest pain. DESIGN -
Plasma levels of catecholamines, beta-thromboglobulin (BTG) and arginine vasopressin (AVP), and degree of pain were examined in 22 patients with suspected uncomplicated myocardial infarction within 24 h following onset of chest pain. Sixteen patients developed infarction with peak creatine
Of patients with acute myocardial infarction eligible for the International Study of Infarct Survival-4, randomized to captopril (n = 30) or placebo (n = 33), the captopril group had a significant decrease in blood adrenaline on day 3 compared with baseline values. Results suggest that suppression
In patients with myocardial infarction, with or without cardiogenic shock, plasma noradrenaline and adrenaline concentrations are increased. However, plasma noradrenaline concentrations are considerably higher in patients with cardiogenic shock when compared with those with uncomplicated myocardial
Plasma concentration of beta thromboglobulin was used as an index of in vivo platelet activation in 36 patients after acute myocardial infarction. Twelve patients had diabetes, seven had pulmonary oedema or cardiogenic shock (pump failure) or both, and 17 had uncomplicated infarcts. On the first day
Valsartan is a specific angiotensin II antagonist used for the treatment of hypertension. It suffers from low aqueous solubility and high variability in its absorption after oral administration. The aim of this study was to improve the dissolution and thereby the bioavailability of Valsartan through
The changes in the content of K+ ions, in the respiration and oxidative phosphorylation were studied in the mytochondria of canine hearts 5 and 30 min following the ligation of the left descending coronary artery. The gradual changes in the content of intramytochondrial K+ in the mytochondria of the
Noradrenaline and adrenalin levels in different sections of the heart of persons deceased of myocardial infarction were measured, this being paralleled by determining the content of the said amines in the adrenal glands. It is shown that the noradrenaline level in the myocardium was down by
