Background and Aims: Cardiac hypertrophy is a compensatory augmentation response of the heart due to pressure overload that can lead to heart failure. Carvacrol is considered as the major compound of many plants, that possesses strong antioxidant properties. The present study aimed to evaluate effect of carvacrol on catalase activity and mRNA expression following left ventricular hypertrop...

Objective: Several studies have shown that Chichorium intybus L. (C. intybus) which possesses flavonoid compounds has an effective role in treatment of cardiovascular diseases. Contractile dysfunction mostly occurs after acute myocardial infarction, cardiac bypass surgery, heart transplantation and coronary angioplasty. The aim of the present study was to investigate the effect of aqueous extra...

The left ventricular end-systolic pressure-volume relationship is a load-insensitive measure of left ventricular performance. The relationship at end-systole between left ventricular pressure and dimension is more easily obtained, but the conflicting results of previous studies make it unclear if it has the same properties as the left ventricular end-systolic pressure-volume relationship. To ad...

Acute pulmonary edema during hypertensive crisis has been attributed to acute left ventricular systolic failure secondary to increased afterload. We tested the hypothesis that the increase in coronary artery perfusion pressure associated with systemic hypertension could also contribute to increased left ventricular filling pressures by acutely increasing coronary intravascular volume and decrea...

background: exercise and rehabilitation are important methods for decreasing the risk factors of coronary artery disease (cad). we aimed to evaluate the effect of the cardiac rehabilitation (cr) exercise program on the cardiac structure and physiology in patients undergoing percutaneous coronary intervention (pci). methods: in this randomized controlled study, 146 patients with cad were divided...

To evaluate the mechanism of the abnormal motion of the interventricular septum (IVS) seen echocardiographically in some patients with relatively delayed ventricular activation, we simultaneously recorded high-fidelity left and right ventricular pressures and electrograms and echocardiograms of the IVS in nine open-chest dogs. During sinus rhythm and during left IVS pacing, the IVS was activate...

Echocardiographic and hemodynamic data were measured in closed-chest dogs during graded cardiac tamponade (pericardial pressure 5, 10, and 15 mm Hg) before and after production of diffuse ischemic left ventricular dysfunction. Left ventricular dysfunction was produced by intracoronary injection of nonradioactive microspheres (54 +/- 3.9 mm diameter). Changes in left atrial pressure with cardiac...
