Nuclear cardiology laboratories provide diagnostic services as part of standard care in many hospitals worldwide. In 2008, a world-wide survey of nuclear cardiology procedures was reported by the Working Group on Nuclear Cardiology for the International Atomic Energy Agency. High nuclear cardiology utilization (.1000 procedures/100 000 population) was reported in the USA, Canada, and Israel, an...

Background Cardiac magnetic resonance imaging (CMR) with delayed gadolinium enhancement (DE) enables accurate infarct size measurement, however, the evaluation of infarct size using a threshold method is time consuming and relies on accurate placement of normal regions of interest and manual delineation of the infarct size. The purpose of the study was to analyze the accuracy and expenditure of...

Determination of myocardial infarct size is important for clinical management of patients with ischemic heart disease and for research on limiting infarct size. Nuclear magnetic resonance (NMR) imaging permits tomographic depiction of the distribution of mobile tissue protons. NMR images have demonstrated high spatial resolution and contrast. To evaluate the potential of this technique in measu...

objective(s) dracocephalum moldavica (d. moldavica) have been traditionally used as a cardiotonic agent in the folk medicine of some regions of iran. in the present study, effects of total extract of d. moldavica on ischemia/reperfusion induced arrhythmias and infarct size investigated in isolated rat heart. materials and methods the isolated hearts were mounted on a langendorff apparatus then ...

For the increasing number of patients who survive an acute myocardial infarction, infarct size is the main determinant of further prognosis (1). Timely reperfusion is mandatory to reduce infarct size, and for all conditioning strategies— ischemic pre-conditioning, delayed ischemic pre-conditioning, ischemic post-conditioning, and remote pre-conditioning— reperfusion is a prerequisite to reduce ...

objective(s):to investigate the effects of local mild hypothermia on the expression of fas, fasl and mmp-3 after cerebral ischemia-reperfusion in rats. materials and methods:male wistar rats were divided into sham-operated group (sham), normothermia group (nt), and hypothermia group (ht). mcao/r model was established by longa’s method, and reperfusion was allowed after 2 hr occlusion. mild hypo...

Background: The objective of this study was to review the patient characteristics and operative results in patients with postinfarction ventricular septal rupture (VSR) based on infarct-related vessel.
