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...
