Disease relevance of Angiography

• Thus in patients with mild CAD nifedipine substantially suppresses disease progression as shown by the appearance of new lesions detectable by quantitative coronary arteriography [1].

• If episodes of ischemic ST segment shift continued, the therapy of group 1 was added to that of group 2 or vice versa; if further ST segment changes were documented, intravenous heparin and oral beta-blockers were added; if episodes of myocardial ischemia persisted, urgent coronary arteriography and myocardial revascularization were performed [4].
• Myocardial biopsy, coronary arteriography and left ventricular angiography were used to define and differentiate congestive cardiomyopathy and myocarditis [5].

Psychiatry related information on Angiography

• Three elderly men being evaluated for cerebrovascular disease developed acute confusional states following arteriography with approximately 50 ml of meglumine iothalamate [6].

High impact information on Angiography

• Follow-up clinical information was collected every six months, and coronary arteriography and thallium stress scanning were performed at one and three years [7].
• MR angiography is a noninvasive technique with greater sensitivity than conventional contrast arteriography for detecting distal runoff vessels in patients with peripheral arterial occlusive disease [8].
• Heart rate, arterial pressure, blood flow in the coronary sinus (measured by thermodilution), and the dimensions of the epicardial left coronary artery (measured by quantitative arteriography) were measured before and 15 minutes after the intranasal administration of saline (in 16 patients) or cocaine (in 29) [9].
• Thirty-seven patients (31%) sustained a significant reduction in creatine clearance after arteriography [10].
• Postdilation arteriography demonstrated a substantial increase in luminal diameter, and ankle pressure indexes were improved in all successful cases [11].

Chemical compound and disease context of Angiography

• The acute effects of small doses of intravenous propranolol on renin release and on circulatory dynamics were studied at the time of renal arteriography in 12 persons with essential hypertension [12].
• Exercise SPECT thallium imaging and coronary arteriography were performed for evaluation of chest pain in 243 women [13].
• Total cholesterol level, high-density lipoprotein (HDL) cholesterol level, and the ratio of total cholesterol/HDL cholesterol and triglyceride level were determined in 128 consecutive patients undergoing coronary arteriography for evaluation of chest pain [14].
• Herein is described a severely uremic patient who had an acute myocardial infarction shortly after discontinuance of diltiazem, although results of subsequent coronary arteriography were normal [15].
• Artifacts of arteriography include magnification, thrombus effect, fore-shortening of tortuosity, loss of luminal detail, parallax error, and projection errors [16].

Biological context of Angiography

• Infarct size and viability imaged by PET using generator-produced rubidium-82 were quantified objectively by automated software and related to coronary arteriography, left ventricular ejection fraction, revascularization and 3-year mortality [17].
• The diagnostic value of maximal pharmacologic coronary vasodilation with intravenously administered adenosine in conjunction with thallium-201 single-photon emission computed tomography (SPECT) for detection of coronary artery disease was investigated in 101 consecutive patients who had concomitant coronary arteriography [18].
• To evaluate the possibility that sustained platelet activation occurs in association with arteriography, we measured the platelet-specific protein beta thromboglobulin (BTG) prior to and 24 hours following arteriography in two groups of patients [19].
• In the dopamine group, there was no deterioration in creatinine clearance on either day, and mean effective renal plasma flow during and after arteriography was greater [20].
• Celiac and splenic arteriography was used in the triage of patients for nonsurgical treatment or for hemostasis [21].

Anatomical context of Angiography

• The use of the 99m technetium-tagged erythrocyte scanning to localize the bleeding site and arteriography to document a vascular malformation strongly suggested this diagnosis [22].
• Prior to surgery, an extensive and rigorous protocol to localize the gastrinoma was carried out, including hypotonic duodenography, abdominal ultrasonography, selective arteriography, portal vein sampling for gastrin, and computerized tomography [23].
• Saphenous vein graft obstruction rates were compared among three groups classified by serum cholesterol levels at follow-up arteriography: group I < 200 mg/dl; group II 200 to 239 mg/dl; group III > or = 240 mg/dl [24].
• Probucol did not induce regression over the 3-year trial period as estimated by change in lumen volume on quantitative arteriography of a 20-cm segment of the femoral artery [25].
• The leukocyte ascorbic acid level was found significantly lower in patients with coronary arteriography [26].

Associations of Angiography with chemical compounds

• PURPOSE: We re-established a formerly identified cohort of neurological patients receiving injections of Thorotrast for cerebral arteriography and assessed their incidence of cancer [27].
• 21 digital fluorescein and indocyanine-green angiographies were obtained from 11 adult patients, and 77 angiograms were obtained from age-matched controls [28].
• Patency of the graft was demonstrated by technetium scan and arteriography and followed by a color-coded Doppler imaging system [29].
• 348 patients (82%) underwent repeat arteriography 3 years later; 282 (134 nifedipine, 148 placebo) had received treatment throughout, but treatment had been stopped in 39 nifedipine-treated and 27 placebo-treated patients after average periods of 354 and 467 days [1].
• STUDY OBJECTIVE: To determine whether estrogen replacement therapy affects the prevalence of severely obstructive coronary arterial lesions defined by selective coronary arteriography [30].

Gene context of Angiography

• Coronary arteriography was performed 90 min and 24 h after the start of t-PA [31].
• Major gene evidence after MTHFR-segregation analysis of serum homocysteine in families of patients undergoing coronary arteriography [32].
• In this patient, the celiac trunk was occluded at its root and the splenic and left gastric artery could be visualized serially via the enlarged collateral artery on superior mesenteric arteriography [33].
• MR images (n = 22), CT during arterial portography (n = 20), and CT hepatic arteriography (n = 17) were retrospectively correlated quantitatively and qualitatively with VEGF expression in HCCs and in the surrounding liver assessed by western blotting [34].
• An efficient protocol for the evaluation of hypertensive cases included renal arteriography, suppression and stimulation of the renin-aldosterone system, and, when indicated, renal venous renin measurements [35].

Analytical, diagnostic and therapeutic context of Angiography

• Exercise-induced ST-segment elevation in leads V1 and/or aVL in the absence of anterior Q waves occurred in 46 of 190 patients (24%) who underwent 12-lead exercise electrocardiography with thallium-201 myocardial perfusion imaging and coronary arteriography [36].
• Coronary arteriography was performed at 2, 5, 15, and 30 minutes after PTCA and then 3 minutes after 300 micrograms i.c. nitroglycerin [37].
• The clinical utility of exercise thallium-201 single photon emission computed tomography was investigated in 360 consecutive patients who had concomitant coronary arteriography [38].
