abstract introduction: doppler echocardiography is used to evaluate global myocardial performance. an index of myocardial performance (tei index) can be of great prognostic value in heart failure. this study was performed to assess the correlation between tei index (ti) and left ventricular end diastolic pressure (lvedp). methods: the study group consisted of 38 patients. each patient underwent...
Ventricular Dysfunction To the Editor: Brookes et al1 reported decreased left ventricular (LV) systolic performance during right ventricular (RV) ischemia in the pig and concluded that “The hemodynamic compromise seen in association with acute RV dilatation within an intact pericardium is partly attributable to impaired LV systolic performance and cannot be wholly ascribed to changes in either ...
conclusions patients faced with isolated left ventricular apical hypoplasia should be monitored by echocardiography because of this disease’s possible progressive trend to life-threatening consequences. introduction isolated left ventricular apical hypoplasia is an unusual type of cardiomyopathy that presents with different clinical manifestations according to the age of the disease, ranging fr...
conclusions gated spect mpi has a good correlation with echocardiography for the measurement of left ventricular ef, edv, and esv in patients with severe heart failure. however, the absolute values of these functional parameters from echocardiography and gated spect mpi measured with different software packages should not be used interchangeably. results a good correlation was found between ech...
the disease of thalassemia major requires mangement by repeated transfusions of packed cell and iron chelators such as deferoxamine. today, serum ferritin is used for estimation of adequacy of the management. as the most morbidities and mortalities of the disease are the consequences of cardiac complications. echocardiography is periodically periodically performed along with the management. in ...
background : left ventricular (lv) dyssynchrony is a prevalent feature in heart failure (hf) patients. the current study aimed to evaluate the prevalence of inter and intraventricular dyssynchrony in hf patients with regard to the qrs duration and etiology. methods: the available data on the tissue doppler imaging (tdi) of 230 patients with refractory hf were analyzed. the patients were divided...
Contractile performance of hypertrophied left ventricle may be depressed in arterial hypertension. Ventriculoarterial coupling is impaired when myocardial contractile performance is reduced and when afterload is increased. The left ventricular contractile performance and the ventriculoarterial coupling were evaluated in 30 hypertensive patients with moderate left ventricular hypertrophy and 20 ...
Introduction: Exercise plays an important role in promoting cardiovascular function. Also concurrent endurance and resistance training can have different effects on the heart. The purpose of this study was to investigate the effect of endurance, resistance and concurrent resistance and endurance training on the heart structure of healthy middle-aged women. Materials and Methods: Forty healt...
Objective: IQSPECT is an advanced high-speed SPECT modality for performing myocardial perfusion imaging (MPI), which uses a multi-focus fan beam collimator with resolution recovery reconstruction. The aim of this study was to compare IQSPECT compared with conventional SPECT interms of performance based on standard clinical protocols. In addition, we examined the concordance between convention...
left ventricular non-compaction cardiomyopathy is a rare congenital cardiomyopathy that affects both children and adults. since the clinical manifestations are not sufficient to establish diagnosis, echocardiography is the diagnostic tool that makes it possible to document ventricular non-compaction and establish prognostic factors. we report a 47-year-old woman with a history of dilated cardio...
