M-mode and two-dimensional parasternal long axis view echocardiography, and left anterior oblique cineangiography were employed to assess the left ventricular wall motion in 10 normal subjects (N) and in 25 patients with hypertrophic cardiomyopathy: 7 patients with symmetric hypertrophy (SH) and 6
Coronary arteriovenous fistula (CAVF) is a rare form of congenital heart disease. However, it is the most common type of congenital coronary artery anomalies.[1][2].An arteriovenous fistula is an abnormal conduit between the artery and vein, typically bypassing the capillaries in between. When
BACKGROUND
In adult patients, certain levels of PEEP (16 and 20 cm H(2)O) have been associated with left ventricular (LV) regional wall motion abnormalities. Since any increase in intra-abdominal pressure (IAP) exerted by a pneumoperitoneum is transmitted to the intrathoracic cavity, similar effects
The paper presents the review of the literature data and the results of the authors' own experience in the aspects of the origin and clinical interpretation of "innocent" cardiac murmurs (ICM). It was suggested that ICM were a regular phenomenon in the majority of the young people. Contradictions in
The aim of this prospective study was to determine the mortality risk factors in patients with chronic obstructive pulmonary disease (COPD). Eighty-six COPD patients were observed during 3 to 5 years. The presence and the severity of COPD were established according to COPD criteria (1998).
Laser transmyocardial revascularization, a procedure originally intended to simulate the perfusion mechanism of the reptilian heart, has evolved into an effective but poorly understood treatment for angina when traditional revascularization is not an option. Herein, we review the explanations that
A study is presented of 38 patients with severe iron-deficiency anemia and 70 patients with non-severe iron-deficiency anemia. All patients showed hypotension with a mean arterial pressure from 70.0 to 76.6 mm Hg. With progression of the severity of iron- deficiency anemia the patients exhibited a
OBJECTIVE
Supraventricular tachycardia and ventricular tachycardia are often observed in patients with hypertrophic cardiomyopathy (HCM) and they often alter the clinical features of HCM. We examine the influence of supraventricular tachycardia on cardiac function and assess the clinical
Radionuclide ventriculography using the technique of first label passage through cardiac cavities was performed in 60 male patients (mean age 46.8 years) who had suffered myocardial infarction (MI) 3-8 months prior to the investigation. Total and local left-ventricular functions were assessed on the
Takotsubo cardiomyopathy is an acute, reversible form of left ventricular dysfunction precipitated by emotional or physical stress. The condition is important to recognise as it mimics acute myocardial infarction and acute coronary syndrome. Most patients are female and postmenopausal. Presenting
Supplementary intraventricular flow during the left ventricular isovolumic relaxation period "isovolumic relaxation flow", was described for the first time in 1987 by Sasson. This flow was searched for in 13 patients with hypertrophic obstructive cardiomyopathy (HOCM), 58 patients with aortic valve
A study was made of the echocardiographic signs of heart lesion in 23 influenza patients in the acute disease period and in 19 of them, during early convalescence. Echocardiography permits detecting alterations in cases where clinically or with the aid of the ECG, the diagnosis of myocardial lesions
To study regional wall motion early in the development of acute myocardial infarction, left ventriculograms performed in 24 patients before thrombolysis and within 3.5(1.2) (mean (SD] hours of the onset of pain were digitised frame by frame. Isometric and contour plots of regional wall motion were
The increasing application of nanoparticles (NPs) to a variety of new technologies has become a matter of concern due to the potential toxicity of these materials. Many questions about the fate of NPs in the environment and the subsequent impact on ecosystems need to be answered. The aim of this
Portal hypertension induces neuroendocrine activation and a hyperkinetic circulation state. This study investigated the consequences of portal hypertension on heart structure and function. Intrahepatic portal hypertension was induced in male Sprague-Dawley rats by chronic bile duct ligation (CBDL).
