Cardiovascular risk factors and magnesium: relationships to atherosclerosis, ischemic heart disease and hypertension.

Magnesium and trace elements

Altura BM, Altura BT.
PMID: 1844551
Magnes Trace Elem. 1991-1992;10(2):182-92.

Hypertension and atherosclerosis are well-known precursors of ischemic heart disease, stroke and sudden cardiac death. Although there is general agreement that the atheroma is the hallmark of atherosclerosis and is found in coronary obstruction, there is no agreement as...

Comparative effects of halothane associated with verapamil and ischaemia on myocardial metabolism in isolated perfused rat hearts.

European journal of anaesthesiology

Arvieux CC, Pernin C, Drouet N, Mathieu JP, Hamant S, Dubois F, Cuchet P, Stieglitz P, Comet M.
PMID: 1425613
Eur J Anaesthesiol. 1992 Nov;9(6):447-55.

The association of verapamil with halothane causes ischaemic-like myocardial dysfunction. Using an isolated rat heart model perfused with a radiolabelled fatty acid (123I-labelled iodohexadecenoic acid) as a sensitive marker of ischaemia this study investigated whether or not this dysfunction...

Ventricular function and calcium handling during ischemia.

Journal of cardiovascular pharmacology

Amende I, Bentivegna L, Morgan JP.
PMID: 1282612
J Cardiovasc Pharmacol. 1992;20:S42.

Ischemia-induced ventricular dysfunction has been shown to be associated with increased diastolic and systolic intracellular concentrations of free, ionized calcium ([CA2+]i). The present study was designed to determine the effects of the calcium antagonist nisoldipine on the relationship between...

Reperfusion arrhythmias after chronic regional denervation of the ischaemic myocardium in pigs.

Cardiovascular research

Cinca J, Worner F, Carreño A, Bardají A, Salas-Caudevilla A, Soler-Soler J.
PMID: 1486589
Cardiovasc Res. 1992 Oct;26(10):962-7. doi: 10.1093/cvr/26.10.962.

OBJECTIVE: The aim was to assess the effects of chronic regional denervation of the ischaemic myocardium on reperfusion arrhythmias in a model with sparse coronary collateral circulation.METHODS: Baseline ventricular refractoriness and epicardial activation times were measured together with reperfusion...

Myocardial fatty acid oxidation during ischemia and reperfusion.

Molecular and cellular biochemistry

Lerch R, Tamm C, Papageorgiou I, Benzi RH.
PMID: 1282666
Mol Cell Biochem. 1992 Oct 21;116(1):103-9. doi: 10.1007/BF01270576.

Inhibition of fatty acid oxidation is an early event in myocardial ischemia that most likely contributes to tissue injury by the accumulation of potentially toxic intermediates such as acylCoA and acylcarnitine. After reperfusion both myocardial oxygen consumption and fatty...

Thallium-201: what do we gain from new clinical protocols and acquisition procedures? The Italian Study on Thallium Reinjection/SIRT).

Journal of nuclear biology and medicine (Turin, Italy : 1991)

Inglese E, Brambilla M, Dondi M, Coccolini S, Cannizzaro G, Pirelli S, Cappagli M, Bertoli D, Pieri PL, Moscatelli G.
PMID: 1486118
J Nucl Biol Med. 1992 Jul-Sep;36(3):253-8.

Nine medical centers, equipped with the same gamma camera and computer software, participated in this multicenter study on thallium-201 reinjection imaging. Preliminary findings for the first 143 patients with ischemic heart disease and perfusion defects at stress imaging are...

Release kinetics of cardiac troponin T in coronary effluent from isolated rat hearts during hypoxia and reoxygenation.

Basic research in cardiology

Asayama J, Yamahara Y, Ohta B, Miyazaki H, Tatsumi T, Matsumoto T, Inoue D, Nakagawa M.
PMID: 1463427
Basic Res Cardiol. 1992 Sep-Oct;87(5):428-36. doi: 10.1007/BF00795055.

A newly developed troponin T (TnT) test for the detection of myocardial cell necrosis has been reported to be very efficient in the detection of acute myocardial infarction. The aim of the present study was to determine whether cardiac...

Influence of KATP channel modulation on net potassium efflux from ischaemic mammalian cardiac tissue.

Cardiovascular research

Vanheel B, de Hemptinne A.
PMID: 1291079
Cardiovasc Res. 1992 Nov;26(11):1030-9. doi: 10.1093/cvr/26.11.1030.

OBJECTIVE: The aim was to investigate the effect of pre-exposure to inhibitors or activators of the ATP regulated K+ (KATP) channels on the ischaemia induced early changes of the extracellular K+ concentration, the extracellular pH, and the action potential...

Metabolic effects of adenosine on regional myocardial ischemia by phosphorus 31 nuclear magnetic resonance spectroscopy.

American heart journal

Marcovitz PM, Aisen AM, Fencil LE, Swanson SD, Buda AJ.
PMID: 1442487
Am Heart J. 1992 Nov;124(5):1205-12. doi: 10.1016/0002-8703(92)90401-g.

The metabolic effects of adenosine on regionally ischemic myocardium were investigated in an open-chest rabbit model by means of phosphorus 31 nuclear magnetic resonance (NMR) spectroscopy. Sixteen anesthetized New Zealand white rabbits were subjected to thoracotomy; a reversible snare...

["Stunned myocardium"--laboratory curiosity or clinically relevant phenomenon of myocardial failure?].

Przeglad lekarski

Andres J.
PMID: 7938651
Przegl Lek. 1994;51(5):213-6.

Reversible contractile dysfunction ("myocardial stunning") now is recognized in laboratory animals as well as in the clinic. The precise mechanism(s) responsible for this transient decrease in myocardial contractility is at present unknown. However substantial body of experimental evidence suggest...

Evidence for norepinephrine cardiotoxicity mediated by superoxide anion radicals in isolated rabbit hearts.

Naunyn-Schmiedeberg's archives of pharmacology

Rump AF, Klaus W.
PMID: 7911559
Naunyn Schmiedebergs Arch Pharmacol. 1994 Mar;349(3):295-300. doi: 10.1007/BF00169296.

UNLABELLED: Catecholamines have been demonstrated to be cardiotoxic. Besides hemodynamic alterations, oxygen free radicals generated by the auto-oxidation of catecholamines might contribute to their deleterious effects. We examined the influence of exogenous norepinephrine (NE), after inhibiting functional alterations by...
