BACKGROUND Past studies have clearly established that matrix metalloproteinases (MMPs) contribute to adverse myocardial remodeling with ischemia and reperfusion. However, these studies measured MMP levels in extracted samples, and therefore whether and to what degree actual changes in interstitial MMP activity occur within the human myocardium in the context of ischemia/reperfusion remained unk...

Minimally invasive surgery has been used in the treatment of some cardiovascular diseases. Port-Access surgery is a new minimally invasive technique that utilizes cardiopulmonary by-pass and a specialized catheter system that provides cardiopulmonary support and myocardial preservation. Extrathoracic cardiopulmonary support is established with femero-femoral bypass with kinetic assisted venous ...

The test system was created by adding flex and force sensors to this manikin evaluate the results of heart massage applied on an artificial adult manikin, which has a spring that can give chest stiffness human. This monitors analyzes cardiopulmonary resuscitation (CPR) applications performed automated CPR device or manually person. signals received from sensor are transferred computer via seria...

conclusions our study showed superiority of off-pump cabg regarding lvef, rvef and valves regurgitations. future studies with prospective structure, accurate randomization, longer follow up duration, and larger sample size are needed. results one hundred eighteen patients with the mean age of 59.47 ± 9.68 years were included (81 male and 37 female). on-pump cabg was done on 84 patients and off-...

conclusions the survival rate after in-hospital cpr was very low. the duration of cpr and the time of initiating cpr effects patients’ outcomes. these findings highlight the crucial role of an organized, skilled, well-established and timely cpr team. background despite several studies, there is no agreement on factors that affect survival after in-hospital cardiopulmonary resuscitation (cpr). o...
