Objective(s) This study aimed to examine whether acetyl-L-carnitine (ALC) was able to reduce cardiac arrhythmias and infarct size in the ischemic-reperfused isolated rat heart. Materials and Methods The isolated hearts were mounted on a Langendorff apparatus then perfused by a modified Krebs-Henseleit solution during 30 min regional ischemia and 120 min reperfusion (control) or by enriched K...

objective(s): some histopathological alterations take place in the ischemic regions following brain ischemia. recent studies have demonstrated some neuroprotective roles of crocin in different models of experimental cerebral ischemia. here, we investigated the probable neuroprotective effects of crocin on the brain infarction and histopathological changes after transient model of focal cerebral...

objective: ischemic preconditioning (ipc) is an endogenous phenomenon that can induce ischemic tolerance (it) in variety of organs such as brain. in this study, we examined the intermittent and prolonged normobaric hyperoxia (ho) on neurologic deficit scores, infarct volume, and superoxide dismutase activity. materials and methods: the rats were divided to four main groups. first two main grou...

The effects of early intracoronary streptokinase (SK) on enzymatic infarct size and rate of enzyme release were studied in a randomized multicenter trial. A total of 533 patients with acute myocardial infarction (AMI) were allocated to either the SK treatment group (n = 269) or the conventional (control) treatment group (n = 264). Enzymatic infarct size was represented by the cumulative quantit...

BACKGROUND Standard extracellular cardiovascular magnetic resonance (CMR) contrast agents (CA) do not provide differentiation between acute and older myocardial infarcts (MI). The purpose of this study was to develop a method for differentiation between acute and older myocardial infarct using myocardial late-enhancement (LE) CMR by a new, low molecular weight contrast agent.Dogs (n = 6) were s...

To determine the clinical consequences of reocclusion of an infarct-related artery after reperfusion therapy, we evaluated 810 patients with acute myocardial infarction. Patients were admitted into four sequential studies with similar entry criteria in which patency of the infarct-related artery was assessed by coronary arteriography 90 minutes after onset of thrombolytic therapy. Successful re...

BACKGROUND Prompt reperfusion in patients with ST-segment elevation myocardial infarction (STEMI) reduces infarct size and improves survival. However, the intuitive link between infarct size and prognosis has not been convincingly demonstrated in the contemporary era. OBJECTIVES This study sought to determine the strength of the relationship between infarct size assessed early after primary p...

Renal infarction usually occurs against a background of heart disease or a thromboembolic tendency and rarely is associated with infections. Here we present a case of a young boy who reported with painless gross hematuria following primary Varicella infection and was found to have an isolated renal infarct.

Watershed infarcts (WI) evolve in hemodynamic risk zones. Clinical picture of WI can be associated to partial epileptic seizures. Diffusion weighted brain magnetic resonance imaging (MRI) allows a clear diagnosis. WI pathogenesis involves either embolic or hemodynamic mechanism. A 69-year old patient presented with sub-acute occurrence of right hemiparesis and partial epileptic seizures of the ...
