Recent developments in the field of echocardiography have allowed the cardiologist to objectively quantify regional and global myocardial function. Regional deformation (strain) and deformation rate (strain-rate) can be calculated non-invasively in both the left and right ventricle, providing information on regional (dys-)function in a variety of clinical(More)
It has been postulated that a reduction in blood viscosity due to degradation of plasma fibrinogen may be of benefit to patients with acute myocardial infarction (AMI), who are treated with thrombolytic agents. The aims of this study were to investigate the time course of rheologic parameters, to identify the principal factors determining blood viscosity,(More)
We describe a patient who developed a severe coagulopathy after being bitten by a red-necked keelback snake (Rhabdophis subminiatus), a species which is generally considered non-venomous. The patient's blood was incoagulable due to complete depletion of fibrinogen. Comprehensive coagulation studies were performed to identify the mechanism(s) by which the(More)
Because it can accurately detect preserved glucose metabolism even in the hypoperfused or stunned myocardium, 18-FDG-PET is considered as the gold standard of myocardial viability assessment. In tako-tsubo cardiomyopathy, a presumed condition of stunning, absence of glucose metabolism however is not a marker of death. This sheds a critical light on(More)
In this article we present the myocardial deformation imaging (MDI) studies of three daughters of a man with hypertrophic cardiomyopathy (HCM) who died suddenly. The daughters had been referred for genetic counselling several months earlier. We demonstrate that, despite the absence of conventional two-dimensional echo characteristics of HCM, MDI accurately(More)
Measurement of mode chirping in a current-modulated semiconductor laser was performed using a Michelson interferometer. For a current step excitation, the rate of this chirping decays as a function of time, and two characteristic time constants were identified. Their interpretation is discussed, and the thermal impedance of the device is calculated. In(More)
European physicians may occasionally be confronted with cases of snake venom poisoning. The increasing interest in snakes as pets has unfortunately resulted in the importation of a number of venomous snakes. We here report the third known case in the medical literature of a patient who was exposed to severe coagulopathy after being bitten by a 'harmless'(More)
Left ventricular hypertrophy (LVH) is an independent risk factor for the development of heart failure, coronary heart disease and stroke. LVH develops in response to haemodynamic overload, e.g. hypertension. LVH was originally thought to start as an adaptive and beneficial response required to normalise wall stress. However, this concept has been challenged(More)
