in the current study, effects of acute short term administration of fructose on cardiac arrhythmias and myocardial infarction size following ischemia/reperfusion were investigated in isolated rat heart. the hearts were subjected to 30 min zero flow global ischemia followed by 120 min reperfusion. in the control group, the hearts were perfused by normal drug free krebs-henseleit (k/h) solution t...

Brief ischemic periods lead to myocardial dysfunction without myocardial infarction. It has been shown that expression of inducible HSP70 in hearts of transgenic mice leads to decreased infarct size, but it remains unclear if HSP70 can also protect against myocardial dysfunction after brief ischemia. To investigate this question, we developed a mouse model in which regional myocardial function ...

Venoarterial extracorporeal membrane oxygenation (ECMO) can provide temporary cardiopulmonary support for patients in hemodynamic extremis or refractory heart failure until more durable therapies-such as cardiac transplantation or a left ventricular assist device-can be safely implemented. Conventional ECMO cannulation strategies commonly employ the femoral artery and vein, constraining the pat...

Abstract Background Leptin exerts both protective and deleterious effects on the heart; first occurs under hypoxia- or ischemia-associated damage, second is a pro-hypertrophic factor cardiomyocytes. Therefore, leptin could represent link between obesity cardiovascular diseases. The study aimed to investigate effect of leptin—the same concentration that frequently measured in induces cardiac hyp...

Competent management of patients with an invasive temporary pacemaker is an important skill for nurses who provide care for critically ill patients with cardiac disease. Such management requires familiarity with normal cardiovascular anatomy and physiology, conduction system defects, and rhythm interpretation. With an understanding of the basic concepts of rate, output, chambers, sensitivity, a...

BACKGROUND AND PURPOSE The significance of brain temperature to outcome in cerebral ischemia is recognized. Numerous variations of depth, duration, and delay of cooling have been studied in animal models. It is important to become familiar with these studies to design appropriate clinical trials. With that in mind, a critical review of the pertinent literature is presented, taking into consider...
