Rough sets (Pawlak Z. Rough Sets: Theoretical Aspects of Reasoning about Data, Dordrecht: Kluwer Academic Publishers, 1991) is a relatively new approach to representing and reasoning with incomplete and uncertain knowledge. This article introduces the basic concepts of rough sets and Boolean
Some reports suggest that mitral valve repair has good outcomes and may, therefore, be the preferred surgical approach in patients with active infective endocarditis (Doukas et al. in Heart 92(3):361-363, 2006); Ruttmann et al. in J Thorac Cardiovasc Surg 130(3):765-771, 2005; Sternik et al. in J
High-resolution real-time 3-dimensional echocardiography (RT3DE) allows observation of the left ventricular endocardial surface in vivo. This study was performed to characterize the endocardial surface structure and its contractile function in the myocardial infarction (MI) zone in relation to the
There has been disagreement about the precise characteristics of "subcortical aphasia." We evaluated 14 patients with aphasia after subcortical lesions and controlled for duration, general anatomic site of lesions (capsulostriatal only), and etiology. The clinical profiles of the patients were quite
A TCI1 rough surface left ventricular assist device (LVAD) was implanted in a 47-year-old man who had sustained a recent massive myocardial infarction complicated by ventricular failure which remained unresponsive to intra-aortic balloon pump therapy and which was further complicated by irreversible
This paper evaluates the variable selection performed by several machine-learning techniques on a myocardial infarction data set. The focus of this work is to determine which of 43 input variables are considered relevant for prediction of myocardial infarction. The algorithms investigated were
An ultrastructural study of cerebral infarcts in spontaneously hypertensive rats 1--5 h after bilateral carotid artery occlusion was performed. The alteration of the neocortex consisted of shrinkage of the neurons surrounded by swollen astrocytic processes. Distension of the rough endoplasmic
Electrocardiography is an evolving clinical diagnostic modality for detection of acute myocardial infarction. Animal studies and electrocardiographic-clinical-pathological correlations have provided experience currently used for detection and rough localization of myocardial infarcts. Additions to
A patient suffering from bilateral thalamic infarction in the region supplied by the paramedian arteries sparing the internal capsules underwent acoustic analysis of sentence utterances. The results were compared with the findings obtained in parkinsonian subjects, in patients with upper motor
Active contiguous abnormalities can frequently involve the pericardium. Prominent among these are cardiac conditions which encroach on the pericardium, particularly transmural myocardial infarction (newly always with Q-waves). Complications of infarctions, notably myocardial pseudoaneurysm, have one
In 38 patients after myocardial infarction changes of the main parameters of the central haemodynamics have been found with the aid of tetrapolar transthoracic rheography and phonotachooscillography as compared with a control group (20 practically healthy individuals). A direct interrelationship has
From an autopsy series of 346 patients who died of acute myocardial infarction, we selected 36 cases for whom echocardiographic data preceding death were available: 17 cases died from a rupture of the left ventricular free wall (group A) and 19 from pump failure (group B). Our aim was to investigate
In 580 patients with a definite myocardial infarction (MI) and no previous MI, the enzymatically estimated infarct size was related to the clinical course including various complications. In all patients, heat-stable lactate dehydrogenase activity (EC 1.1.1.27, LD) was analyzed every 12 hours for
The left ventricular hemodynamics of 70 patients with acute myocardial infarction were determined from measurements of pulmonary arterial end-diastolic pressure, cardiac index, mean arterial pressure and heart rate during the acute phase(first study, 5 hours after admission), 4 to 6 weeks later
Blood stasis (BS) is characterized as a disorder of blood circulation. In traditional Korean medicine (TKM), it is viewed as a cause factor of diseases such as multiple sclerosis and stroke. This study investigated differences in the plasma metabolites profiles of subjects displaying BS or non-BS
