Adenosine released by ischemic myocardial cells stimulates coronary artery vasodilation. Measurement of adenosine concentrations in pericardial fluid in animal models of myocardial ischemia has been used to study the process of adenosine release. To determine whether pericardial fluid adenosine concentrations are increased in human ischemic heart disease, adenosine concentrations were measured ...

BACKGROUND Data on the prevalence of valvular heart disease in very old individuals are scarce and based mostly on in-hospital series. In addition, the potential detrimental effect of valvular heart disease on the activities of daily living is unknown. The present study evaluated the prevalence of significant valvular heart disease and the impact of valvular heart disease on the activities of d...

background: recent interests have mainly focused on the roles of serum calcium and phosphorus and their product (ca-p product) in the development of valvular heart disease. the present study assessed the relationship between the ca-p product and the severity of valvular heart disease in end-stage renal disease (esrd) patients undergoing chronic hemodialysis. methods: this cross-sectional study ...

The occurrence of cognitive disorders is a common problem after surgery. degree worsening functions surgery and anesthesia has significant impact on the patient's health significantly associated with prolonged recovery in hospital, increased morbidity delayed functional recovery. aim study was to increase effectiveness diagnosis moderate impairment determine its gender age characteristics patie...

IT IS an obvious fact that acquired valvular deformities may impose a serious mechanical burden upon the heart. Over the years it has been logical to hope that definitive surgical technics would be developed to alter these defects so as to restore normal cardiac function. However plausible the need, the evolution of surgery for acquired valvular disease was delayed by the fear that the heart co...

This paper studies hemodynamic changes after repairing congenital valvular heart disease. Two categories of Tetralogy Fallot (TOF) and (ASD Primum) were collected from the Nasiriyah Heart Center between January 2015 February 2022, with findings for 50 patients (28 TOF & 22 ASD Primum). The results showed that spo2 value before Surgery was low compared to its Surgery, which due existence ste...

2013 was the year of transcatheter heart valve interventions. Not least because of the 2012 European guidelines on the management of valvular heart disease (VHD), the multidisciplinary heart team approach became an established concept. Decision-making, when a patient is too ‘sick’ for surgery and too ‘healthy’ for catheter-based interventions, is complex, since VHD is often seen at an older age...

Cardiac surgery continues to play a key role in our therapeutic arsenal against many heart diseases. This is still the case despite the recent and striking progress regarding specific drugs or different forms of cardiac intervention. However, in relation to the elderly patient, this therapeutic modality is one of the fields where agebased discrimination has been practiced for years, that is, th...

Eighteen patients, 15 to 74 years of age, in intractable and life-threatening heart failure underwent emergency open heart surgery. There were 14 long term survivors. One hundred percent mortality was predicted withont the application of surgery. The cause of failure was valvular heart disease in 14 and coronary heart disease in four patients. Assisted circulation during the most critical perio...
