BACKGROUND AND PURPOSE We have developed a dynamic CT method to measure absolute cerebral blood flow (CBF), cerebral blood volume (CBV), and mean transit time (MTT). In this study we evaluated the ability of CT-derived functional maps to detect infarction in a rabbit model of focal cerebral ischemia. METHODS Sequential dynamic CT studies were performed at 2 different slices in 5 control rabbi...

Introduction: Recent studies demonstrated that cannabidiol had neuroprotective property. Thereis some evidence about effective role of cannabidiol in reducing ischemic damages. It has been reported that infarct size is influenced by various factors after MCAO, including inflammatory factors. The aim of the present study was to evaluate the effect of cannabidiol on infarction volume and correlat...

Several studies addressed the association between Intercellular adhesion molecule 1 (ICAM-1) rs5498 polymorphism and Myocardial Infarction (MI) risk. However, they addressed conflicting findings. Therefore, the aim of this study was to explore whether ICAM-1 gene rs5498 polymorphism plays an important role in modifying the risk of MI. A meta-analysis was conducted on the association between ICA...

We discuss a sample size calculation for a pair-matched case-control study to test for interaction between a specific exposure and a second risk factor. The second risk factor could be either binary or continuous. An algorithm for the calculation of sample size is suggested which is based on a logistic regression model that relates the logarithm of the disease-exposure odds ratio to the second ...

Thirty seven patients with acute myocardial infarction were studied to determine the effect of perfusion of the infarct artery on the relation between the extent of initial ST segment elevation and final electrocardiographic infarct size. The sum of the initial peak ST elevations in all leads correlated with electrocardiographic infarct size in patients with anterior infarction and total occlus...

The distance from the midline to the left heart border measured in a standardized manner on calibrated chest roentgenograms was determined serially in 125 patients after acute myocardial infarction. This external left heart dimension (LHD) was compared to the normal value, and its prognostic value was assessed during early and late follow-up periods (average 10, range 2-31 months). Within 96 ho...

BACKGROUND The prediction of the ventricular remodeling process after acute myocardial infarction (AMI) may have important clinical implications. OBJECTIVE To analyze echocardiographic variables predictors of remodeling in the infarction model in rats. MEHTODS: The animals underwent echocardiography in two moments, five days and three months after infarction (AMI group) or sham surgery (contr...

Until recently, the use of nitroglycerin in patients with acute myocardial infarction has been contraindicated primarily because of possible hypotension or tachycardia which, with sublingual or oral preparations, would be difficult to control. The introduction of intravenous nitroglycerin and its use during experimentally induced infarction paved the way for its use in patients with acute myoca...
