noradrenaline/infarction

OBJECTIVE Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is characterized by ultrastructural abnormalities in small cerebral and systemic vessels. We assessed vasomotor function in systemic small arteries in CADASIL. METHODS We studied 10 CADASIL

BACKGROUND Our previous study showed that pretreatment with noradrenaline via opening of the mitochondrial ATP-sensitive potassium channel protects myocardium against ischemia/reperfusion injuries. We have hypothesized that production of nitric oxide (NO) and generation of reactive oxygen species

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 Carvedilol Acute Myocardial Infarction Study (CAMIS) investigates cardiac remodeling in patients (n = 250) randomized to carvedilol vs atenolol and treated for 12 months after acute myocardial infarction. In a sub-study, we compared sympathetic, hemorrheological and vascular effects in small but

We tested the hypothesis that arterial reactivity to noradrenaline is augmented in congestive heart failure (CHF), which could contribute to the deleterious changes in peripheral vascular resistance and compliance in this condition. From male Wistar rats with post-infarction CHF and sham-operated

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

OBJECTIVE The aim was to evaluate mechanisms regulating tissue noradrenaline in congestive heart failure. METHODS Tissue noradrenaline was measured in the conscious post myocardial infarction rat model of congestive heart failure and in sham operated rats (1) under control conditions, (2) 6 h after

The comparative hemodynamic effects of dobutamine and dopamine were studied in 6 patients with low cardiac output resulting from acute myocardial infarction. Plasma levels of noradrenaline and renin were measured before and during a 5 microgram/kg/min infusion of each of the drugs. Dobutamine had a

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

Isolated rat hearts were perfused with buffer containing noradrenaline 10(-7) to 10(-4) M. A dose-dependent depletion of glycogen and ATP were seen together with a leakage of ASAT and creatine phosphokinase (CK). The damage induced by noradrenaline could be prevented by addition of a beta-blocker

A significant decrease of the noradrenaline content of the ischemic as well as non-ischemic parts of the myocardium was found in rats after ligation of the left coronary artery. The eventual role of released noradrenaline in the anaerobic metabolism of the heart was investigated. A highly
