Effect of long-term remote ischemic conditioning in patients with chronic ischemic heart failure
Archiv für Kreislaufforschung - Tập 112 - Trang 1-11 - 2017

Remote ischemic conditioning (RIC) protects against acute ischemia–reperfusion injury and may also have beneficial effects in patients with stable cardiovascular disease. We investigated the effect of long-term RIC treatment in patients with chronic ischaemic heart failure (CIHF). In a parallel group study, 22 patients with compensated CIHF and 21 matched control subjects without heart failure or ...... hiện toàn bộ

Release kinetics and correlation with hemodynamic dysfunction of cardiac troponin T in coronary effluent from isolated rat hearts during reperfusion
Archiv für Kreislaufforschung - Tập 88 - Trang 307-313 - 1993
Y. Yamahara, J. Asayama, B. Ohta, T. Matsumoto, H. Miyazaki, T. Tatsumi, M. Kobara, M. Inoue, D. Inoue, M. Nakagawa
Previously, we reported that cardiac troponin T (TnT) can be detected and measured in coronary effluent from isolated rat hearts during hypoxia. The present study was designed to evaluate the release kinetics of TnT from post-ischemic rat hearts. Using the Langendorff technique, the hearts were reperfused for 4h after 20 min or 60 min of global ischemia. Coronary flow was measured by timing the co...... hiện toàn bộ
Further studies on the effects of myosin P-light chain phosphorylation on contractile properties of skinned cardiac fibres
Archiv für Kreislaufforschung - Tập 81 - Trang 611-619 - 1986
I. Morano, H. Arndt, C. Bächle-Stolz, J. C. Rüegg
We investigated the influence of myosin P-light chain phosphorylation by Ca2+-calmodulin dependent myosin light chain kinase (MLCK) on the sensitivity of the tension-pCa relation and maximum unloaded shortening velocity (v max) of chemically skinned heart fibres of the pig. Submaximum Ca2+ stimulation (pCa 5.5) induced 20±5% of the isometric tension achieved at maximum Ca2+ activation (pCa 4.3). M...... hiện toàn bộ
Connective tissue content and myocardial stiffness in pressure overload hypertrophy A combined study of morphologic, morphometric, biochemical, and mechanical parameters
Archiv für Kreislaufforschung - Tập 78 - Trang 140-155
I. Medugorac, Ch. Holubarsch, R. Jacob, K. -U. Thiedemann
We investigated samples of left ventricular myocardium from Goldblatt II (4 and 8 weeks after operation) and spontaneously hypertensive rats (SHR; 40 and 80 weeks old) by histological and morphometric methods. From the same hearts, the distensibility of the left ventricular papillary muscle was analyzed by means of resting tension curves, and the collagen content of the whole left ventricular wall...... hiện toàn bộ
Contractile performance, mitochondrial function and blood flow distribution in porcine heart with induced coronary collateral circulation
Archiv für Kreislaufforschung - Tập 78 - Trang 62-76 - 1983
J. H. Ngai, M. A. Matlib, R. W. Millard
Progressive stenosis of the proximal left anterior descending coronary artery in young pigs was surgically induced over eight weeks and was accompanied by the development of coronary collateral circulation originating from the right coronary artery. The antero-apical left ventricular myocardium dependent on this induced collateral blood supply became hypokinetic compared with the other regions of ...... hiện toàn bộ

Doppler myocardial imaging. A new tool to assess regional inhomogeneity in cardiac function
Archiv für Kreislaufforschung - Tập 96 - Trang 595-605 - 2001
Frank Weidemann, Miroslaw Kowalski, Jan D'hooge, Bart Bijnens, George R. Sutherland
In echocardiography, there is still a need for a better tool to quantify regional myocardial function. Doppler myocardial imaging (DMI) allows the calculation of local myocardial velocity profiles for segmental motion in both the radial and longitudinal direction. From the local velocity profile data, 1-dimensional regional myocardial strain rates (SR) and strain (ε) can now be calculated. These ...... hiện toàn bộ
Aging-associated insulin resistance predisposes to hypertension and its reversal by exercise: the role of vascular vasorelaxation to insulin
Archiv für Kreislaufforschung - Tập 104 - Trang 269-284 - 2008
Qiu-Xia Li, Zheng-Ying Xiong, Bai-Ping Hu, Zhen-Jun Tian, Hai-Feng Zhang, Wen-Yi Gou, Hai-Chang Wang, Feng Gao, Quan-Jiang Zhang
Aging is an independent risk factor for hypertension, and hypertension and insulin resistance commonly coexist in the elderly. This study was designed to examine the effects of aging-related insulin resistance on blood pressure (BP) and its underlying mechanisms, with specific focus on the role of exercise in reversing hypertensive response. Adult (6-month-old) and aging (24-month-old) male Spragu...... hiện toàn bộ
Structural and functional imaging by MRI
Archiv für Kreislaufforschung - Tập 103 - Trang 152-160 - 2008
René M. Botnar, Eike Nagel
Magnetic resonance imaging is one of the most exciting techniques for noninvasive molecular imaging of the cardiovascular system. The article will describe challenges, solutions and results of magnetic resonance plaque imaging ex-vivo, in the experimental animal and in patients.
