repetitive episodes of brief regional ischemia have been shown to reduce the severity of life-threatening ventricular anhythrnias and infarct size that occur during prolonged occlusion of the coronary artery. this phenomenon is known as ischemic preconditioning. during studies in anesthetized, open chest wistar rats, we accidentally observed that poorly ventilated animals had a reduced severity...

myocardial dysfunction is a major complication in cardiac surgery that needs inotropic support. this study evaluates the effect of milrinone on patients with low ventricular ejection fraction undergoing off- pump coronary artery bypass graft (opcab). the present study is designed to evaluate the effect of milrinone on myocardial dysfunction. eighty patients with low ventricular ejection fractio...

Objective(s): Ventricular arrhythmias including ventricular tachycardia (VT) and ventricular fibrillation (VF) are the most important causes of mortality rate. Gallic acid (GA) has beneficial effects on cardiovascular diseases. The aim of this study was to evaluate the effects of GA on electrophysiological parameters such as QRS complex, heart rate (HR), PR interval pa...

The meaning of the hypertropy word is the increasing size.Heart hypertropy is symptoms of increase the thickness of the heart muscle that the left ventricular hypertrophy of them is the most common.The causes of hypertrophy heart disease are high blood pressure , aortic valve stenosis and sport activities respectively. Assessment of that by using ECG signal analysis is essential Because the ris...

the disease of thalassemia major requires mangement by repeated transfusions of packed cell and iron chelators such as deferoxamine. today, serum ferritin is used for estimation of adequacy of the management. as the most morbidities and mortalities of the disease are the consequences of cardiac complications. echocardiography is periodically periodically performed along with the management. in ...

background: an electrocardiogram (ecg) can provide information on subclinical myocardial damage. the presence, and more importantly, the quantity of coronary artery calcification (cac), relates well with the overall severity of the atherosclerotic process. a strong relation has been demonstrated between coronary calcium burden and the incidence of myocardial infarction, a relation independent o...

introduction left ventricular free wall rupture (lvfwr) is a frequent cause of death after acute myocardial infarction, and its repair remains a surgical challenge. conclusions a hemodynamic study was acceptable at a 12-month follow-up, and no complication was seen. case presentation tachosil® is a ready-to-use equine collagen patch which has been successfully used for hemostasis in cardiovascu...
