[Metabolic changes and their mechanical consequences in acute myocardial ischemia].

Cardiologia (Rome, Italy)

Ambrosio G, Chiariello M.
PMID: 1841794
Cardiologia. 1991 Dec;36(12):379-87.

The recent advances in cardiovascular pathophysiology have changed our interpretation of the interplay between myocardial metabolism and contractile function which takes place during acute ischemia. For instance, the use of nuclear magnetic resonance (NMR) spectroscopy has allowed to document...

Left ventricular hypertrophy and diastolic dysfunction.

Hospital practice (Office ed.)

Lorell BH.
PMID: 1400669
Hosp Pract (Off Ed). 1992 Oct 15;27(10):189-94, 196, 199 passim. doi: 10.1080/21548331.1992.11705515.

The hypertrophied heart generally preserves systolic function, but it pays a price in diastolic dysfunction. Coronary reserve is impaired and susceptibility to myocardial ischemia increased. The pathophysiology is managed by addressing causes of pressure overload, preventing tachycardia, or, of...

Differences in myocardial ischemic tolerance between 1- and 7-day-old rabbits.

Canadian journal of physiology and pharmacology

Lopaschuk GD, Spafford MA.
PMID: 1490250
Can J Physiol Pharmacol. 1992 Oct;70(10):1315-23. doi: 10.1139/y92-184.

Between 1 and 7 days of life, the newborn rabbit heart shifts from predominantly using carbohydrates to predominantly using fatty acids as an energy substrate. We therefore used isolated working hearts from 1- or 7-day-old rabbits to determine the...

[Changes in hypophyseal-thyroid system function and in the level of atrial natriuretic factor and cyclic nucleotides in the blood of patients with ischemic heart disease exposed to ultrasonic irradiation of the precordial area].


Mrochek AG, Sytyĭ VP, Lifshits IB, Sherstiuk GV, Rudenko EV.
PMID: 1487880
Kardiologiia. 1992 Jul;32(7):48-50.

Radiation of the precordial region with ultrasound at 880 kHz, 0.4 W/cm2 for 12 minutes was examined for its impact on blood levels of thyrotropin, tri-iodothyronine, thyroxine, atrial natriuretic factor, cyclic nucleotides (cAMP and cHMP) in 70 patients with...

The nucleotide metabolism in lactate perfused hearts under ischaemic and reperfused conditions.

Molecular and cellular biochemistry

de Groot MJ, Coumans WA, van der Vusse GJ.
PMID: 1488052
Mol Cell Biochem. 1992 Dec 02;118(1):1-14. doi: 10.1007/BF00249689.

It was examined whether lactate influences postischaemic hemodynamic recovery as a function of the duration of ischaemia and whether changes in high-energy phosphate metabolism under ischaemic and reperfused conditions could be held responsible for impairment of cardiac function. To...

[Mechanism of the antiarrhythmic effect of laser irradiation].

Biulleten' eksperimental'noi biologii i meditsiny

Mikhaĭlova SD, Storozhakov GI, Gukova SIu, Semushkina TM.
PMID: 1421248
Biull Eksp Biol Med. 1992 May;113(5):460-2.

Acute experiments were performed to study the role of afferent impulses from the heart receptors which pass by different vagal fibers during intraatrial laser irradiation. Double laser irradiation of the right atrium seemed more effective than a single one...

Non-invasive evaluation of cardiac abnormalities in heat stroke pilgrims.

International journal of cardiology

al-Harthi SS, Nouh MS, al-Arfaj H, Qaraquish A, Akhter J, Nouh RM.
PMID: 1452370
Int J Cardiol. 1992 Nov;37(2):151-4. doi: 10.1016/0167-5273(92)90202-e.

Serial electrocardiograms as well as echocardiographic studies of 51 pilgrims suffering from acute heat stroke (mean rectal temperature 41.6 degrees C) were performed. All patients were examined immediately after cooling and 24 h later whenever possible. Regional wall motion...

[The prognostic assessment of the reversibility of myocardial dysfunction in patients with ischemic heart disease after aortocoronary bypass].

Vestnik khirurgii imeni I. I. Grekova

Knyshov GV, Ursulenko VI, Panichkin IuV, Luk'ianov IuN, Furkalo SN, Beshliaga VM.
PMID: 1302970
Vestn Khir Im I I Grek. 1992 Jun;148(6):275-8.

Forty-six patients with ischemic heart disease with considerable dysfunction of the myocardium were subjected before operation of aortocoronary shunting to veloergometry with calculation of indices of the central hemodynamics by the method of tetrapolar rheoplethysmography, echocardioscopy before and after...

Effects of intravenous amiodarone on electrical dispersion in normal and ischaemic tissues and on arrhythmia inducibility: monophasic action potential studies.

Cardiovascular research

Mayuga RD, Singer DH.
PMID: 1451136
Cardiovasc Res. 1992 Jun;26(6):571-9. doi: 10.1093/cvr/26.6.571.

OBJECTIVE: The aim was to study the effects of intravenous amiodarone on: (1) repolarisation and other monophasic action potential characteristics of normal and ischaemic tissues, and (2) vulnerability to pacing induced repetitive ventricular firing following acute left anterior descending...

Alterations in the beta-adrenergic receptor system after hypothermic ischemia in hearts with preischemic beta-receptor desensitization.

The Journal of surgical research

Sakagoshi N, Matsuda H, Watanabe Y, Kaneko M, Sawa Y, Yoshida H, Kawashima Y.
PMID: 1357234
J Surg Res. 1992 Jul;53(1):66-73. doi: 10.1016/0022-4804(92)90015-r.

Although hypothermic cardioplegic arrest is a basic method of myocardial protection in cardiac surgery, the beta-adrenergic receptor (BAR) system has been little investigated in the heart subjected to hypothermic ischemia. Additionally, although the hypothermic arrest is often induced in...

[Reality and enigmas in left ventricular hypertrophy in arterial hypertension].

The influence of clinical intervention on pressure-volume relationships--the conductance (volume) technique.

European heart journal

Thormann J.
PMID: 1478213
Eur Heart J. 1992 Nov;13:69-79. doi: 10.1093/eurheartj/13.suppl_e.69.

We analysed end-systolic pressure-volume relations (ESPVR), using the conductance technique, to study the potential inotropic effects of (1) PDE inhibitor drugs, (2) class 1 anti-arrhythmic drugs and (3) PTCA-induced myocardial ischaemia (MIS). The question of contractility involvement is of...
