The effects of 0.25 mg/kg dipyridamole on left ventricular (LV) pressures, LV dP/dt, heart rate, aortic pressures, left circumflex coronary blood flow, and left circumflex coronary arterial diameters and on calculations of late diastolic coronary resistance and large coronary cross-sectional area were studied in 15 conscious dogs. Injection of dipyridamole, a drug that has a mechanism of action...
BACKGROUND Regadenoson, dipyridamole and adenosine are commonly used vasodilators in myocardial perfusion imaging for the detection of obstructive coronary artery disease. There are few comparative studies of the vasodilator properties of regadenoson, adenosine and dipyridamole in humans. The specific aim of this study was to determine the relative potency of these three vasodilators by quantif...
Aim. The objective of our work was to analyze the pharmacological correction fetal growth retardation syndrome by monotherapy with diosmin and dipyridamole, compare their effectiveness. Materials methods. A retrospective prospective examination 160 pregnant women a single pregnancy at gestational age 28 36 weeks confirmed diagnosis 1 or 2 degrees an asymmetric form carried out. An extended coll...
Chemical substitutions in the structure of the pyrimido-pyrimidine nucleus give rise to pyrimidopyrimidine compounds with platelet antiaggregatory effects, such as RA-8 (dipyridamole), RA233 (mopidamol) and RA-642. All these compounds inhibit platelet aggregation-induced by ADP through an increase in platelet CAMP levels (1,2). Mopidamol, however, is 3-10 times more potent than dipyridamole and...
We present a female patient with atypical chest pain who was referred to our department for ischemia evaluation. 99mTc-MIBI myocardial perfusion scan with dipyridamole stress was performed. Sub-diaphragmatic activity in the hepatic tissue and then in the bowel loops caused severe overlap on the inferior wall even on consecutive delayed images. Dipyridamole stress was repeated for the...
For a better understanding of the hypolipidemic function of dipyridamole, we have studied the comparative effects of diet supplementation with 10% coconut oil with and without dipyridamole on the lipid plasma and lipoprotein composition in chicks. This study was performed under postprandial and food-deprivation (12h) conditions. Coconut oil induced a clear hypercholesterolemia under both feedin...
OBJECTIVES To investigate the effect of intracoronary dipyridamole on the incidence of abrupt vessel closure, myocardial infarction, necessity for bypass grafting, and death following percutaneous transluminal coronary angioplasty (PTCA). PATIENTS Patients were randomly allocated to receive either conventional pretreatment (heparin 15 000 IU and aspirin 500 mg intravenously) or additional int...
In cardiac myocytes, uptake rates of glucose and long-chain fatty acids (FA) are regulated by translocation of GLUT4 and FA translocase (FAT)/CD36, respectively, from intracellular stores to the sarcolemma. Insulin and contractions are two major physiological stimuli able to induce translocation of both transporters and therefore enhance the uptake of both substrates. Interestingly, the cardiov...
We have studied the effects of dipyridamole treatment on chick plasma and lipoprotein composition in postprandial and fasting (12 h) conditions. Plasma cholesterol levels were higher in fasted than in fed chicks, whereas triglycerides declined during starvation. Dipyridamole treatment reduced plasma cholesterol content, mainly of the free cholesterol fraction. In postprandial conditions, total ...
We have studied the effects of dipyridamole treatment on the fatty acid composition of the main lipid classes of chick serum bearing in mind the relationship between platelet aggregation and eicosanoids production from arachidonic acid. In the free fatty acids, percentages of MUFA and n-6 PUFA fell. The effects of dipyridamole appeared to be less pronounced in triglyceride fraction, but more so...
