... The second limitation is that our method cannot be used in patients with intra-cardiac shunts or severe mitral regurgitation. The dye dilution method we used cannot be applied in patients with intra-cardiac shunts or severe mitral regurgitation (31). The severe aortic regurgitation, however, did not vitiate the dye dilution determination of cardiac output (32). ...

... The femoral arteries should be at least 8-mm wide because the closed stent has a diameter of 7.5 millimeters, and other parameters have been evaluated, such as the amount of atheromatous plaques in the aneurism and in its distal end. The distal end of the aneurism has to be free of disease to guarantee good perfusion of the limbs, minimizing the migration of plaques 17,18 . If those criteria are fulfilled, the endovascular approach is done through the femoral artery, which is dissected in one side and punctured on the other. ...

... One of the leading causes of stress in plant species in the Caatinga is the high level of exposure to ultraviolet-B radiation, which is capable of slowing the growth of individuals and decreasing leaf area (ZHAO et al., 2020). This damage varies according to the degree of exposure of the leaves, with leaves closer to the ground being less susceptible to the negative effects of ultraviolet-B radiation due to shading (PARISI et al., 1998). Furthermore, leaves growing in the sun are known to exhibit marked morphological differences when compared to those in the shade. ...

... Obviously this technique does not allow accurate determination of a desired recruitment level, tailored to individual patient response. George and colleagues demonstrated experimentally how variable the maximal recruitment amplitude can be between individual subjects [32]. Furthermore, significant differences in maximal pressure development during muscle contraction can occur with small increases in stimulation voltage which will certainly affect the degree of cardiac assist attained. ...

Latissimus Dorsi Stimulation in Dynamic Cardiomyoplasty: How Should We Proceed?

... The contributory factors are thought to be ischaemia of the muscle flap as a consequence of mobilisation and, possibly, sustained activity. A further consequence of fast-to-slow transformation is slower relaxation of the muscle wrap, which may interfere with the diastolic performance of the heart [15,17,18]. These fundamental concerns about the viability and performance of the LDM can be answered only if more is understood about the changes in nutrition and perfusion that occur within muscles in terms of conditioning and surgical mobilisation. ...

... Depression has also been linked to increased risk of cardiac thrombotic events via platelet reactivity and activation [83]. Upon activation, platelets secrete serotonin, which acts on platelet serotonin receptors to promote aggregation on the platelets [94,95] and causes vasoconstriction of arteries [12,96]. Depressed patients show an up-regulation of serotonin receptors on platelets, leading to increased density of platelet serotonin receptors [97,98] and changes in platelet reactivity and activation [99 -101]. ...

A Topographical Map of the Causal Network of Mechanisms Underlying the Relationship Between Major Depressive Disorder and Coronary Heart Disease

... Autoregulation of coronary circulation plays a major role in the control of myocardial blood flow (MBF). 1,2 It is well known that as coronary artery disease (CAD) progresses, resting flow does not initially change, but MBF (such as that achieved by injecting a vasodilator) decreases progressively. 3 In this setting, coronary autoregulation, reducing the resistance of distal perfusion beds, attempts to preserve adequate MBF and oxygen supply. 4 Only a coronary stenosis exceeding approximately 80% of luminal diameter induces significant reductions in resting MBF, while attenuation of hyperemic flow is detectable in the presence of coronary stenosis of about 45%. ...

... La utilización de antraciclinicos en el tratamiento de neoplasias humanas conlleva a un riesgo de cardiotoxicidad dosis dependiente que puede generar insuficiencia cardiaca (Singal 1998). La doxorrubicina se ha utilizado para inducir insuficiencia cardiaca en perros, ovejas y cabras (Chekanov, 1999;Tessier, 2003;Monnet, 1999;Cheng, 1992;Monnet, 2002). La doxorrubicina se puede administrar vía intravenosa o intracoronaria; esta última modalidad permite la administración de menores dosis evitando la toxicidad sistémica. ...
