Myocardial ischemia results from an imbalance between oxygen supply and demand. After coronary occlusion, oxygen supply and demand mismatch produces a series of physiological alterations that can precede clinical symptoms (1). Impaired myocardial perfusion is an early event in the “ischemic cascade” that can be assessed using clinically available noninvasive imaging. Both extent and severity of...

Heart failure (HF) with preserved ejection fraction (HFpEF) is becoming the predominant form of HF. Understanding cardiac structure and function in this syndrome is highly relevant for diagnosis, prognosis, pathophysiology, and management. However, identifying cardiac dysfunction in HFpEF can be challenging and requires an integrated assessment of cardiac structure, systolic and diastolic funct...

objective: to compare the effects of two auditory methods by mother and fetus on the results of nst in 2011-2012. materials and methods: in this single-blind clinical trial, 213 pregnant women with gestational age of 37-41 weeks who had no pregnancy complications were randomly divided into 3 groups (auditory intervention for mother, auditory intervention for fetus, and control) each containing ...

H. pylori infection is usually acquired in early childhood. Its role in gastrointestinal and extra intestinal complaints and serious consequences in adulthood make it as challenging issues. Despite different clinical presentations, in most children, the presence of H. pylori infection does not lead to clinically apparent disease, even when it causes chronic active gastritis. Some of most import...
