A method of computed tomography that uses radionuclides which emit a single photon of a given energy. The camera is rotated 180 or 360 degrees around the patient to capture images at multiple positions along the arc. The computer is then used to reconstruct the transaxial, sagittal, and coronal images from the 3-dimensional distribution of radionuclides in the organ. The advantages of SPECT are that it can be used to observe biochemical and physiological processes as well as size and volume of the organ. The disadvantage is that, unlike positron-emission tomography where the positron-electron annihilation results in the emission of 2 photons at 180 degrees from each other, SPECT requires physical collimation to line up the photons, which results in the loss of many available photons and hence degrades the image.

Primary biliary cirrhosis associated with membranous glomerulonephritis. (1/980)

A 33-year-old woman was admitted to our department for evaluation of liver dysfunction and proteinuria. A liver biopsy specimen showed ductular proliferation and moderate portal fibrosis indicating stage II primary biliary cirrhosis. A renal biopsy specimen showed mild to moderate mesangial cell proliferation without crescent formation or interstitial nephritis. Immunofluorescent staining revealed deposition of immunoglobulin G (IgG), third component of complement (C3), and Clq on glomerular basement membranes. The findings indicated stage I membranous glomerulonephritis. Administration of ursodesoxycholic acid together with prednisolone, azathioprine, and dipyridamole decreased proteinuria and improved cholestatic liver dysfunction.  (+info)

Integrated evaluation of relation between coronary lesion features and stress echocardiography results: the importance of coronary lesion morphology. (2/980)

OBJECTIVES: The aim of this study was to analyze, in the same group of patients, the relationship between multiple variables of coronary lesion and results of exercise, dobutamine and dipyridamole stress echocardiography tests. BACKGROUND: Integrated evaluation of the relation between stress echocardiography results and angiographic variables should include not only the assessment of stenosis severity but also evaluation of other quantitative and qualitative features of coronary stenosis. METHODS: Study population consisted of 168 (138 male, 30 female, mean age 51+/-9 years) patients, on whom exercise (Bruce treadmill protocol), dobutamine (up to 40 mcg/kg/min) and dipyridamole (0.84 mg/kg over 10 min) stress echocardiography tests were performed. Stress echocardiography test was considered positive for myocardial ischemia when a new wall motion abnormality was observed. One-vessel coronary stenosis ranging from mild stenosis to complete obstruction of the vessel was present in 153 patients, and 15 patients had normal coronary arteries. The observed angiographic variables included particular coronary vessel, stenosis location, the presence of collaterals, plaque morphology according to Ambrose classification, percent diameter stenosis and obstruction diameter as assessed by quantitative coronary arteriography. RESULTS: Covariates significantly associated with the results of physical and pharmacological stress tests included for all three stress modalities presence of collateral circulation, percent diameter stenosis and obstruction diameter, as well as lesion morphology (p < 0.05 for all, except collaterals for dobutamine stress test, p = 0.06). By stepwise multiple logistic regression analysis, the strongest predictor of the outcome of exercise echocardiography test was only percent diameter stenosis (p = 0.0002). However, both dobutamine and particularly dipyridamole stress echocardiography results were associated not only with stenosis severity - percent diameter stenosis (dobutamine, p = 0.04; dipyridamole, p = 0.003) - but also, and even more strongly, with lesion morphology (dobutamine, p = 0.006; dipyridamole, p = 0.0009). As all of stress echocardiography results were significantly associated with percent diameter stenosis, the best angiographic cutoff in relation to the results of stress echocardiography test was: exercise, 54%; dobutamine, 58% and dipyridamole, 60% (p < 0.05 vs. exercise). CONCLUSIONS: Integrated evaluation of angiographic variables have shown that the results of dobutamine and dipyridamole stress echocardiography are not only influenced by stenosis severity but also, and even more importantly, by plaque morphology. The results of exercise stress echocardiography, although separately influenced by plaque morphology, are predominantly influenced by stenosis severity, due to a stronger exercise capacity in provoking myocardial ischemia in milder forms of coronary stenosis.  (+info)

Functional production and reconstitution of the human equilibrative nucleoside transporter (hENT1) in Saccharomyces cerevisiae. Interaction of inhibitors of nucleoside transport with recombinant hENT1 and a glycosylation-defective derivative (hENT1/N48Q). (3/980)

We have produced recombinant human equilibrative nucleoside transporter (hENT1) in the yeast Saccharomyces cerevisiae and have compared the binding of inhibitors of equilibrative nucleoside transport with the wild-type transporter and a N-glycosylation-defective mutant transporter. Equilibrium binding of 3H-labelled nitrobenzylmercaptopurine ribonucleoside {6-[(4-nitrobenzyl)thio]-9-beta-d-ribofuranosyl purine; NBMPR} to hENT1-producing yeast revealed a single class of high-affinity sites that were shown to be in membrane fractions by (1) equilibrium binding (means+/-S.D.) of [3H]NBMPR to intact yeast (Kd 1.2+/-0.2 nM; Bmax 5.0+/-0.5 pmol/mg of protein) and membranes (Kd 0.7+/-0.2 nM; Bmax 6.5+/-1 pmol/mg of protein), and (2) reconstitution of hENT1-mediated [3H]thymidine transport into proteoliposomes that was potently inhibited by NBMPR. Dilazep and dipyridamole inhibited NBMPR binding to hENT1 with IC50 values of 130+/-10 and 380+/-20 nM respectively. The role of N-linked glycosylation in the interaction of NBMPR with hENT1 was examined by the quantification of binding of [3H]NBMPR to yeast producing either wild-type hENT1 or a glycosylation-defective mutant (hENT1/N48Q) in which Asn-48 was converted into Gln. The Kd for binding of NBMPR to hENT1/N48Q was 10. 5+/-1.6 nM, indicating that the replacement of an Asn residue with Gln decreased the affinity of hENT1 for NBMPR. The decreased affinity of hENT1/N48Q for NBMPR was due to an increased rate of dissociation (koff) and a decreased rate of association (kon) of specifically bound [3H]NBMPR because the values for hENT1-producing and hENT1/N48Q-producing yeast were respectively 0.14+/-0.02 and 0. 36+/-0.05 min-1 for koff, and (1.2+/-0.1)x10(8) and (0.40+/-0. 04)x10(8) M-1.min-1 for kon. These results indicated that the conservative conversion of an Asn residue into Gln at position 48 of hENT1 and/or the loss of N-linked glycosylation capability altered the binding characteristics of the transporter for NBMPR, dilazep and dipyridamole.  (+info)

Coronary flow reserve in young men with familial combined hyperlipidemia. (4/980)

BACKGROUND: Familial combined hyperlipidemia (FCHL) is a common hereditary disorder of lipoprotein metabolism estimated to cause 10% to 20% of premature coronary heart disease. We investigated whether functional abnormalities exist in coronary reactivity in asymptomatic patients with FCHL. METHODS AND RESULTS: We studied 21 male FCHL patients (age, 34.8+/-5.4 years) and a matched group of 21 healthy control subjects. Myocardial blood flow (MBF) was measured at baseline and during dipyridamole-induced hyperemia with PET and 15O-labeled water. The baseline MBF was similar in patients and control subjects (0.79+/-0.19 versus 0.88+/-0.20 mL. g-1. min-1, P=NS). An increase in MBF was seen in both groups after dipyridamole infusion, but MBF at maximal vasodilation was lower in FCHL patients (3.54+/-1.59 versus 4.54+/-1.17 mL. g-1. min-1, P=0.025). The difference in coronary flow reserve (CFR) was not statistically significant (4.7+/-2.2 versus 5.3+/-1.6, P=NS, patients versus control subjects). Considerable variability in CFR values was detected within the FCHL group. Patients with phenotype IIB (n=8) had lower flow during hyperemia (2.5+/-1.2 versus 4.2+/-1.5 mL. g-1. min-1, P<0.05) and lower CFR (3.4+/-2.1 versus 5.4+/-2.0, P<0.05) compared with phenotype IIA (n=13). CONCLUSIONS: Abnormalities in coronary flow regulation exist in young asymptomatic FCHL patients expressing phenotype IIB (characterized by abnormalities in both serum cholesterol and triglyceride concentrations). This is in line with previous observations suggesting that the metabolic abnormalities related to the pathophysiology of FCHL are associated with the phenotype IIB.  (+info)

Phasic coronary flow pattern and flow reserve in patients with left bundle branch block and normal coronary arteries. (5/980)

OBJECTIVES: The purpose of this study was to determine whether scintigraphic myocardial perfusion defects in patients with left bundle branch block (LBBB) and normal coronary arteries are related to abnormalities in coronary flow velocity pattern and/or coronary flow reserve. BACKGROUND: Septal or anteroseptal defects on exercise myocardial perfusion scintigraphy are common in patients with LBBB and normal coronary arteries. METHODS: Thirteen patients (7 men, age 61+/-8 years) with LBBB and normal coronary arteries underwent stress thallium-201 scintigraphy and cardiac catheterization. In all patients and in 11 control subjects coronary blood flow parameters were calculated from Doppler measurements of flow velocity in the left anterior descending coronary artery (LAD) before and after adenosine administration. RESULTS: The time to maximum peak diastolic flow velocity was significantly longer both for the seven patients with (134+/-19 ms) and for the six without (136+/-7 ms) exercise perfusion defects than for controls (105+/-12 ms, p < 0.05), whereas the acceleration was slower (170+/-54, 186+/-42 and 279+/-96 cm/s2, respectively, p < 0.05). Coronary flow reserve in the patients with exercise perfusion defects (2.7+/-0.3) was significantly lower than in those without (3.7+/-0.5, p < 0.05) or in the control group (3.4+/-0.5, p < 0.05). CONCLUSIONS: Patients with LBBB have an impairment of early diastolic blood flow in the LAD due to an increase in early diastolic compressive resistance resulting from delayed ventricular relaxation. Furthermore, exercise scintigraphic perfusion defects in these patients are associated with a reduced coronary flow reserve, indicating abnormalities of microvascular function in the same vascular territory.  (+info)

Endothelium-dependent and -independent perfusion reserve and the effect of L-arginine on myocardial perfusion in patients with syndrome X. (6/980)

BACKGROUND: Impaired vasodilatation capacity in patients with angina pectoris and a normal coronary arteriogram (syndrome X [SX]) has been reported. Most studies report on the response in epicardial vessels. This does not necessarily reflect compromised myocardial microcirculation. Lack of the NO precursor L-arginine has been suggested as a possible cause. METHODS AND RESULTS: Myocardial blood flow (MBF) was measured, using PET, at rest (MBF-rest) and during intravenous dipyridamole (MBF-DIP) in 25 women (mean age 53+/-7 years) with SX. Thirty healthy volunteers served as controls. One group (A) consisted of 15 age-matched female volunteers (54+/-10 years). The other control group consisted of 15 young healthy women (B; 24+/-5 years). In 12 SX patients, MBF-rest and MBF during cold pressor testing were also measured after infusion of L-arginine (6.7 g/min for 45 minutes). The increase in MBF after cold pressor testing was similar in the SX group compared with controls. L-arginine did not affect MBF-rest (0.83+/-0.14 versus 0.89+/-0.13 mL. g-1. min-1) or MBF after cold pressor test (0.95+/-0.10 versus 1. 03+/-0.17 mL. g-1min-1). In contrast, the hyperemic response to DIP was blunted compared with the group A controls (1.68+/-0.49 versus 2. 34+/-0.45 mL. g-1. min-1, P<0.05); this resulted in a significant reduction of the coronary flow reserve in SX patients relative to controls (2.03+/-0.53 versus 2.96+/-0.63 mL. g-1. min-1, P<0.01). CONCLUSIONS: In patients with SX, the microcirculatory response to cold, reflecting the endothelium function, is normal and unaltered by intravenous L-arginine. This suggests preserved microcirculatory endothelial function. However, a markedly attenuated hyperemic flow and flow reserve after DIP suggest a dysfunction of the adenosine-mediated endothelium-independent vasodilatation at the microcirculatory level in these patients.  (+info)

Quantification of extracellular and intracellular adenosine production: understanding the transmembranous concentration gradient. (7/980)

BACKGROUND: Inhibitors of adenosine membrane transport cause vasodilation and enhance the plasma adenosine concentration. However, it is unclear why the plasma adenosine concentration rises rather than falls when membrane transport is inhibited. We tested the hypothesis that the cytosolic adenosine concentration exceeds the interstitial concentration under well-oxygenated conditions. METHODS AND RESULTS: In isolated, isovolumically working guinea pig hearts (n=50), the release rate of adenosine and accumulation of S-adenosylhomocysteine (after 20 minutes of 200 micromol/L homocysteine), a measure of the free cytosolic adenosine concentration, were determined in the absence and presence of specific and powerful blockers of adenosine membrane transport (nitrobenzylthioinosine 1 micromol/L), adenosine deaminase (erythro-9-hydroxy-nonyl-adenine 5 micromol/L), and adenosine kinase (iodotubericidine 10 micromol/L). Data analysis with a distributed multicompartment model revealed a total cardiac adenosine production rate of 2294 pmol. min-1. g-1, of which 8% was produced in the extracellular region. Because of a high rate of intracellular metabolism, however, 70.3% of extracellularly produced adenosine was taken up into cellular regions, an effect that was effectively eliminated by membrane transport block. The resulting approximately 2.8-fold increase of the interstitial adenosine concentration evoked near-maximal coronary dilation. CONCLUSIONS: We rejected the hypothesis that the cytosolic adenosine concentration exceeds the interstitial. Rather, there is significant extracellular production, and the parenchymal cell represents a sink, not a source, for adenosine under well-oxygenated conditions.  (+info)

Effects of sevoflurane on regional myocardial blood flow distribution: quantification with myocardial contrast echocardiography. (8/980)

BACKGROUND: Using myocardial contrast echocardiography, the authors tried to determine whether sevoflurane causes myocardial blood maldistribution in humans and dogs. METHODS: In animal experiments, 15 mongrel dogs were organized into dipyridamole (n = 6) and sevoflurane (n = 9) groups. Sonicated albumin was infused into the left main coronary artery. The peak gray level corrected for background was analyzed at the following intervals: (1) at baseline, (2) after stenosis of the left circumflex coronary artery (blood flow reduced by 40%), (3) after administration of dipyridamole (1 mg/kg given intravenously) or sevoflurane (1 minimum alveolar concentration) during stenosis, and (4) after phenylephrine during stenosis and administration of dipyridamole or sevoflurane. In human studies, nine patients undergoing coronary artery bypass grafting were studied. During partial extracorporeal circulation, the peak gray level was analyzed before and 20 min after sevoflurane (1 minimum alveolar concentration). RESULTS: In animal experiments, dipyridamole decreased significantly the inner:outer ratio of the peak gray level in the ischemic area and the ischemic:normal ratio of the peak gray level. After arterial pressure was restored with phenylephrine, neither the inner:outer ratio nor the ischemic:normal ratio improved. In contrast, after sevoflurane administration, the inner:outer ratio and the ischemic:normal ratio remained unchanged, but these increased with phenylephrine. In human studies, sevoflurane did not change the inner:outer ratio in the area supplied by the most stenotic coronary artery. CONCLUSION: These results suggest that dipyridamole, a potent coronary vasodilator, produces maldistribution of coronary blood flow in our dog models, whereas sevoflurane does not do this in animal or human studies.  (+info)

Although dipyridamole produces coronary vasodilation, most reports on dipyridamole effects in animals have failed to show a change in CBF after intravenous infusion of dipyridamole.16 17 18 19 To our knowledge, this is the first study to quantitatively estimate the change in CBF in response to intravenous dipyridamole in humans. We found CBF values for the dipyridamole stress to be lower than those at rest (Table 2⇑ and Figure 2⇑). Dipyridamole stress also caused a significant reduction in Paco2 (Table 1⇑), and the vascular response to Paco2 change caused by the dipyridamole infusion closely followed the response due to hypocapnia (Table 2⇑ and Figure 1⇑). Thus, the decrease in CBF during dipyridamole stress can be explained by the decrease in Paco2 rather than the direct action of dipyridamole on CBF. The decrease in Paco2 during dipyridamole stress is most likely due to the hyperventilation side effect of adenosine.29 It has been reported that large doses of intravenous adenosine and ...

One theoretic possibility is that the beta-blocker could prevent an increase in myocardial oxygen demand by preventing the modest reflex tachycardia that often occurs with dipyridamole infusion. Although heart rate did increase significantly in placebo-treated patients with dipyridamole infusion in the Taillefer et al. (4)study, systolic and diastolic blood pressure fell significantly so that the rate-pressure product remained unchanged. This suggests that dipyridamole infusion did not produce perfusion defects under placebo conditions by increasing myocardial oxygen consumption and inducing ischemia.. The activation of beta-adrenergic receptors by catecholamines induces coronary artery vasodilation, increasing myocardial oxygen supply. Under baseline conditions, beta-blockade produces coronary artery vasoconstriction (5), possibly by leaving alpha-adrenergic activity unopposed. Under conditions of dipyridamole-induced coronary artery vasodilation, however, it has been demonstrated that ...

Dipyridamole (trademarked as Persantine and others) is a medication that inhibits blood clot formation when given chronically and causes blood vessel dilation when given at high doses over a short time. Dipyridamole inhibits the phosphodiesterase enzymes that normally break down cAMP (increasing cellular cAMP levels and blocking the platelet aggregation response to ADP) and/or cGMP. It inhibits the cellular reuptake of adenosine into platelets, red blood cells, and endothelial cells leading to increased extracellular concentrations of adenosine. Dipyridamole is used to dilate blood vessels in people with peripheral arterial disease and coronary artery disease Dipyridamole has been shown to lower pulmonary hypertension without significant drop of systemic blood pressure It inhibits formation of pro-inflammatory cytokines (MCP-1, MMP-9) in vitro and results in reduction of hsCRP in patients. It inhibits proliferation of smooth muscle cells in vivo and modestly increases unassisted patency of ...
Objectives:. The overall goal of this proposal is to develop methods to achieve heart and vascular protection from ischemia and thus improve soldiers performance in adverse environment. The major hypothesis is that new approach and method can be developed to enhance resistance to stress-induced circulatory insufficiency and myocardial ischemia. The goals here are to determine whether a decreased adenosine transporter function is associated with a reduced physiological responsiveness to the vasculo-protective drug persantine using two in vitro endpoints: the ability of persantine 1) to inhibit platelet aggregation and 2) to inhibit [3H] uridine uptake. Both are endpoints that indicate physiological responsiveness. Both relate directly to the cardiovascular protective effects of , that is, persantine the availability of extracellular adenosine level and the anti-platelet property. Specifically, the relationship between circulating adenosine increase to persantine in vivo and blockade of ...
BACKGROUND: Increased sympathetic activity contributes to the progression of heart failure. Adenosine counteracts sympathetic activity by inhibition of presynaptic norepinephrine release and attenuation of the metabolic and contractile responses to beta-adrenergic stimulation. In this study, we tested the hypothesis that the adenosinergic effects (uptake blockade) of dipyridamole may retard the progression of pressure overload hypertrophy in the rat. METHODS AND RESULTS: To verify that the administration of dipyridamole increases myocardial adenosine levels in the rat, epicardial adenosine concentrations were measured from 12 isolated, perfused rat hearts exposed to 10(-7) and 10(-6) mol/l dipyridamole. Adenosine concentrations were increased with both doses of dipyridamole. Also, 9 weeks of dipyridamole treatment resulted in decreased sensitivity to the adenosine A1-receptor agonist, 2-chloro-N6-cyclopentyl adenosine, suggesting that dipyridamole increases adenosine levels in the intact rat. In ...
It is believed that platelet reactivity and interaction with prosthetic cardiac valve surfaces, resulting in abnormally shortened platelet survival time, is a significant factor in thromboembolic complications occurring in connection with prosthetic heart valve replacement.. Dipyridamole has been found to lengthen abnormally shortened platelet survival time in a dose-dependent manner.. In three randomized controlled clinical trials involving 854 patients who had undergone surgical placement of a prosthetic heart valve, dipyridamole, in combination with warfarin, decreased the incidence of postoperative thromboembolic events by 62 to 91% compared to warfarin treatment alone. The incidence of thromboembolic events in patients receiving the combination of dipyridamole and warfarin ranged from 1.2 to 1.8%. In three additional studies involving 392 patients taking dipyridamole and coumarin-like anticoagulants, the incidence of thromboembolic events ranged from 2.3 to 6.9%.. In these trials, the ...

BACKGROUND: Adenosine receptor stimulation induces several effects that could limit ischemia-reperfusion injury. We hypothesize that treatment with the nucleoside uptake inhibitor dipyridamole increases endogenous adenosine and limits ischemia-reperfusion injury in humans. METHODS: Ischemia-reperfusion injury was studied in forearm skeletal muscle by technetium Tc 99m-labeled annexin A5 scintigraphy. Ischemia-reperfusion injury was induced by unilateral forearm ischemic exercise. Immediately on reperfusion, annexin A5 labeled with technetium Tc 99m was administered intravenously, and ischemia-reperfusion injury was expressed as the percentage difference in radioactivity between the experimental arm and the control arm 1 and 4 hours after reperfusion. Targeting was quantified in the region of the thenar muscle and forearm flexor muscles. This approach was used in 9 healthy male volunteers after a 1-week treatment with dipyridamole (200 mg, slow release, twice daily) and in 23 control subjects. ...
A considerable proportion of patients discontinue dipyridamole therapy because of headache. Risk indicators for the development of dipyridamole induced headache were identified by means of an exploratory analysis of data from the European/Australasian Stroke Prevention in Reversible Ischaemia Trial (ESPRIT) and the Second European Stroke Prevention Study (ESPS 2). In ESPRIT, dipyridamole induced headache was significantly associated with female sex, absence of hypertension and non-smoking (area under the receiver operator characteristic (ROC) curve 0.63 (95% CI 0.58 to 0.68)) and in ESPS 2 with female sex and absence of ischaemic lesions on imaging (area under the ROC curve 0.64 (95% CI 0.59 to 0.69 ...
The recommended oral adult dose of dipyridamole for preventing blood clots is 100 mg 4 times daily one hour before meals. If taken with 1 g ASA daily, the dose of dipyridamole can be reduced to 25 mg 4 times daily.. When used for medical tests that examine how well blood is flowing through the heart, dipyridamole is given by injection in a hospital.. Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.. It is important to take this medication exactly as prescribed by your doctor. If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure ...
