Background: Monitoring the performance of cardiac function is a must in monitoring patients with rheumatic heart disease (RHD). Echocardiography main diagnostic tool that plays role function, but existence this only tertiary health services and generally requires special expertise. This study aims to determine correlation between neutrophil lymphocyte ratio (NLR) markers on echocardiography, na...
Background: Hypofractionated radiotherapy (HF) method was introduced to overcome the quickly growing tumor cells as well as shortening whole treatment course in solid tumors such as breast cancers. Here, we compared the incidence of dermatitis and pharyngitis among patients undergoing HF versus conventional fractionationated (CF) radiation therapy following surgery for breast cancer. Methods: ...
To evaluate the significance of persistent negative T waves during severe ischemia, we prospectively studied 62 patients admitted for unstable angina without evidence of recent or ongoing myocardial infarction. A critical stenosis on the left anterior descending coronary artery (LAD), considered as the culprit lesion, was successfully treated by percutaneous transluminal coronary angioplasty (P...
High-speed biplane left ventricular (LV) cineangiograms were analyzed for changes in volume, shape, and dimensions in 35 patients. Ventriculographic studies in ten normal subjects characterized by an ejection fraction (E.F.) of 67±2% and an end-diastolic volume (EDV) of 90 + 8 ml/ m2 were compared with results from 25 patients with isolated mitral regurgitation of varying severity. Patients wit...
To investigate the effects of angiotensin converting enzyme 2 and genes on cardiac remodeling process in heart failure rats. 38 rats were randomly divided into sham-operated group (S group), (H group) exercise (HE group). An incremental load test was used to determine maximum running speed HE group, while S H groups maintained their daily activities. The structure function pathological changes ...
BACKGROUND A number of noninvasive techniques have been used to predict the effectiveness of cardiac resynchronization therapy (CRT) in heart failure patients, in particular left ventricular (LV) reverse remodeling. This study compared the relative predictive values of tissue Doppler imaging (TDI) and strain-rate imaging (SRI) parameters for LV reverse remodeling in patients who received CRT an...
OBJECTIVE To investigate the effect of acupuncture at Neiguan (PC 6) on cardiac function using echocardiography in rat models of myocardial ischemia (MI) induced by isoproterenol (ISO). METHODS Twenty-seven Sprague-Dawley rats were randomly assigned to normal, model, and acupuncture groups. The model and acupuncture groups were given injections of ISO (85 mg/kg) to establish the MI model. Aft...
Fatalities due to anthrax are associated with severe hypotension suggesting that the toxins generated from Bacillus anthracis, lethal toxin (LeTx) and edema toxin (EdTx), have cardiovascular effects. Here, we demonstrate the effects of these toxins and characterize their effects by echocardiography. LeTx leads to a significant reduction in ejection fraction, decreased velocity of propagation (d...
The purpose of this study was to determine the differences in the left ventricular dimensions, mass index and function in school-aged swimmers by echocardiography. The study group consisted of 82 swimmers who participated in a systematic swimming training for at least six months, and the control group consisted of 41 sedentary children of similar age, sex and weight. In the study group, left ve...
