Right atrial pacing was performed in 21 patients with and 10 patients without coronary artery disease (CAD). The values for the control (C) and maximum paced (P) heart rate were similar in all patients. During pacing cardiac output did not change, and mean arterial pressure remained constant except for a slight increase during pacing-induced angina pectoris in 11 patients with CAD. Left ventric...

Coagulation factor VIII, von Willebrand factor, antithrombin, fibrinogen, plasminogen activator capacity, and inhibitors of fibrinolysis, including a recently discovered fast inhibitor of tissue plasminogen activator, were measured three to six months after myocardial infarction in 116 male and 32 female patients aged less than 45 and in 136 age and sex matched random controls. Plasma concentra...

GENERALIZED hypothermia, as employed in cardiac surgery,' involves a number of factors, some of which are of benefit, others detrimental to myocardial performance. For example, the decreased arterial pressure and the increased blood viscosity tend to reduce coronary blood flow. On the other hand, the reduced metabolic rate of heart muscle, the diminished cardiac work, and the lengthened time fo...

• Severe thermal burn produces in the dog an immediate and profound reduction in the cardiac output. This finding was reported originally by Gilmore and Handford, Dobson and Warner, and has been confirmed by other investigators.The decrease in cardiac output is unrelated to changes in right atrial pressure, and occurs too rapidly to be explained on the basis of changes in plasma volume or heart...

Background: Nowadays, cardiovascular diseases (CVDs) are among the most common causes of mortalities worldwide. Parathyroid hormone (PTH) has an important role in the pathogenesis of CVDs. The aim of the current study was to compare serum PTH levels between patients with acute myocardial infarction (MI), unstable angina, and normal coronary function. Methods: This descriptive and analytic stud...

background: primary percutaneous coronary intervention (primary pci) is the method of choice in establishing reperfusion in acute myocardial infarction (ami) patients. the aim of this study was to determine the success rate of primary pci in a university medical center in iran with a view to promoting it as a first-line therapy in patients with ami, especially in centers with established cathet...

acute myocardial infarction can culminate in sudden cardiac death due to cardiogenic shock and ventricular fibrillation, and also rarely due to cardiac rupture. we present a case of post-infarction myocardial rupture after thrombolytic therapy diagnosed with transthoracic echocardiography and treated with direct closure and coronary artery bypass grafting.

conclusions the vibratory innocent murmur is associated with the presence of left ventricular false tendon and higher left ventricular outflow tract velocity. the presence of the left ventricular false tendon was somewhat associated with decreased early diastolic myocardial velocity. normal left ventricular systolic and diastolic function can be used as a reassurance in cases with the vibratory...
