background: assessment of myocardial function is essential in heart disease, but in regard to systolic and diastolic functions such evaluation has limitation. ejection fraction is difficult to assess in abnormally-shaped ventricles, and diastolic inflow velocity pattern may be fused because of tachycardia. objective: a myocardial performance index (mpi) or tei index has been developed for adu...
Although both dopamine and dobutamine are potent positive inotropic agents, multiple studies indicate that dopamine may produce a rise in left ventricular (LV) filling pressure, while dobutamine often has the opposite effect. To ascertain the pharmacological and hemodynamic mechanisms responsible for the elevation in LV filling pressure observed with dopamine, we administered incremental infusi...
چکیده سابقه و هدف: با توجه به شیوع بالای بیماری ahf و بالا بودن درصد بیماران دیاستولیک دیس فانکشن در این گروه و اهمیت اطلاع از نشانگری (marker) برای تشخیص به موقع و گزارشاتی از نشانگر ctni در این بیماران و عدم اطلاع از وضعیت آن در کشور، به منظور فراوانی نشانگر ctni در بیماران ahf (pef) این تحقیق روی مراجعه کنندگان بیمارستان آیت اله طالقانی انجام شد. روش بررسی تحقیق به روش مقطعی روی کلیه بیماران...
Introduction: Cardiovascular abnormalities have been reported in liver cirrhosis (LC). In these patients, cardiac symptoms and physical signs occur as the liver functions worsen. Cirrhosis is associated with hyper dynamic circulation and beta-adrenergic system changes responsible for the cardiovascular abnormalities. The purpose of the present study was to explore the echocardiographic findi...
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...
