The Electrocardiogram in Population Studies
Ovid Technologies (Wolters Kluwer Health) - Tập 21 Số 6 - Trang 1160-1175 - 1960
Henry Blackburn, Ancel Keys, Ernst Simonson, Pentti M. Rautaharju, Sven Punsar
Information now available about the prevalence and incidence of coronary heart disease is seriously deficient because of the lack of standardized and objective methods of collection, tabulation, interpretation, and reporting of survey data. Chief reliance in the objective diagnosis of coronary heart disease rests on the electr...... hiện toàn bộ
Hormonal Changes and Catabolic/Anabolic Imbalance in Chronic Heart Failure and Their Importance for Cardiac Cachexia
Ovid Technologies (Wolters Kluwer Health) - Tập 96 Số 2 - Trang 526-534 - 1997
Stefan D. Anker, Tuan Peng Chua, Piotr Ponikowski, Derek Harrington, J. Swan, Wolfgang J. Kox, Philip A. Poole‐Wilson, Andrew J.S. Coats
Background The role of hormonal and cytokine abnormalities in the development of cardiac cachexia remains obscure. Methods and Results Healthy control subjects (n=16) and patients with chronic heart failure (CHF), classified clinically as cachectic (...... hiện toàn bộ
Randomized Study to Assess the Effectiveness of Slow- and Moderate-Release Polymer-Based Paclitaxel-Eluting Stents for Coronary Artery Lesions
Ovid Technologies (Wolters Kluwer Health) - Tập 108 Số 7 - Trang 788-794 - 2003
Antonio Colombo, J Drzewiecki, Adrian Banning, Eberhard Grube, Karl Eugen Hauptmann, Sigmund Silber, Dariusz Dudek, Stephen Fort, François Schiele, K Zmudka, Giulio Guagliumi, Mary E. Russell
Background— Early clinical studies demonstrated the feasibility of local paclitaxel delivery in reducing restenosis after treatment of de novo coronary lesions in small patient populations. Methods a...... hiện toàn bộ
Echocardiographic measurements in normal subjects. Growth-related changes that occur between infancy and early adulthood.
Ovid Technologies (Wolters Kluwer Health) - Tập 57 Số 2 - Trang 278-285 - 1978
Walter L. Henry, James S. Ware, Julius M. Gardin, Seymour I. Hepner, Joshua McKay, Menachem M. Weiner
Echocardiographic measurements of the left ventricular dimensions and wall thicknesses at end diastole and end systole, aortic root and left atrial dimensions, mitral valve E-F slope, left ventricular ejection fraction, percent fractional shortening of the left ventricular internal dimension, estimated left ventricular mass and percentage systolic thickening of the ventricular septum and l...... hiện toàn bộ
Diagnostic and prognostic value of dipyridamole echocardiography in patients with suspected coronary artery disease. Comparison with exercise electrocardiography.
Ovid Technologies (Wolters Kluwer Health) - Tập 89 Số 3 - Trang 1160-1173 - 1994
Silva Severi, E. Picano, Claudio Michelassi, Fabio Lattanzi, Patrizia Landi, A. Distante, Antonio L’Abbate
BACKGROUND Before any new diagnostic test is accepted in clinical practice, such a test should be compared with established diagnostic tools in an appropriately large series of patients encompassing the complete spectrum of challenges to which the test is exposed. The aim of the present study was to assess the relative diagnostic ...... hiện toàn bộ
Assessment of anatomic and physiological severity of single-vessel coronary artery lesions by dipyridamole echocardiography. Comparison with positron emission tomography and quantitative arteriography.
Ovid Technologies (Wolters Kluwer Health) - Tập 89 Số 2 - Trang 753-761 - 1994
E. Picano, Oberdan Parodi, Fabio Lattanzi, Gianmario Sambuceti, Maria João Andrade, Paolo Marzullo, Assuero Giorgetti, Piero Salvadori, Mario Marzilli, A. Distante
BACKGROUND The aim of this study was to compare the results of dipyridamole-echocardiography test (DET: two-dimensional echo monitoring during dipyridamole infusion up to 0.84 mg/kg over a period of 10 minutes) with both anatomic and physiological parameters of coronary artery disease severity, assessed by computer-assisted quanti...... hiện toàn bộ
Angiographic and hemodynamic determinants of myocardial ischemia during adenosine thallium-201 scintigraphy in coronary artery disease.
Ovid Technologies (Wolters Kluwer Health) - Tập 87 Số 4 - Trang 1211-1219 - 1993
Shotaro Nishimura, K. T. Kimball, J J Mahmarian, Mario S. Verani
BACKGROUND Myocardial ischemia attributed to coronary steal may occur in some patients receiving pharmacological coronary vasodilation. ECG ST-segment depression is a marker of myocardial ischemia in these patients, but the factors determining the presence or absence of ischemia are not well known. ...... hiện toàn bộ
Quantitative thallium-201 redistribution with a fixed coronary stenosis in dogs.
Ovid Technologies (Wolters Kluwer Health) - Tập 63 Số 3 - Trang 632-639 - 1981
J A Leppo, J.G. Rosenkrantz, Robert L. Rosenthal, Robert Bontemps, Tada Yipintsoi
The redistribution of thallium-201 (201Tl) after coronary vasodilation was studied in 14 dogs with a proximal stenosis of the left circumflex coronary artery that did not reduce basal flow but attenuated reactive hypermia. During an 8-10-minute i.v. infusion of adenosine, radioactive microspheres and 201Tl were injected into the left atrium. Sequential cardiac scintiscans and microsphere i...... hiện toàn bộ
Effects of adenosine on human coronary arterial circulation.
Ovid Technologies (Wolters Kluwer Health) - Tập 82 Số 5 - Trang 1595-1606 - 1990
R F Wilson, Karen Fraser Wyche, Betsy V. Christensen, Sebastian Zimmer, D D Laxson
Adenosine is a potent vasodilator used extensively to study the coronary circulation of animals. Its use in humans, however, has been hampered by lack of knowledge about its effects on the human coronary circulation and by concern about its safety. We investigated in humans the effects of adenosine, administered by intracoronary bolus (2-16 micrograms), intracoronary infusion (10-240 micro...... hiện toàn bộ
Intrinsic washout rates of thallium-201 in normal and ischemic myocardium after dipyridamole-induced vasodilation.
Ovid Technologies (Wolters Kluwer Health) - Tập 71 Số 2 - Trang 378-386 - 1985
G A Beller, Henry H. Holzgrefe, Denny D. Watson
Infusion of dipyridamole has been suggested as an alternative to exercise stress for myocardial perfusion imaging for detection of ischemia, but the mechanism and significance of thallium-201 (201Tl) redistribution after administration of dipyridamole are uncertain. If disparate intrinsic cellular efflux rates of 201Tl from normal and relatively underperfused myocardium in response to dipy...... hiện toàn bộ
