چکیده

Methods Twelve healthy volunteers aged 30±1 years (control group) and 14 asymptomatic patients with severe aortic regurgitation aged 29±2 years and left ventricular ejection fraction of 0.61±0.02 (radioisotope ventriculography) were studied. High-resolution ultrasonography was performed to measure the systolic and diastolic diameters of the common carotid artery. Simultaneous measurement of blood pressure enabled the calculation of arterial compliance and distensibility.

Cytomegalovirus Seropositivity Is Associated with Increased Arterial Stiffness in Patients with Chronic Kidney Disease

BACKGROUND Patients with chronic kidney disease have an increased cardiovascular risk that is not fully explained by traditional risk factors but appears to be related to increased arterial stiffness. Cytomegalovirus (CMV) infection is associated with increased cardiovascular risk although the mechanisms for this are unknown. We examined whether CMV seropositivity was associated with increased ...

Aortic Valve replacement with Reduction Aortoplasty with Mesh Prosthesis in 75 years old with Sever aortic Regurgitation with Aortic Aneurysm

Although classic and standard procedure for patients with ascending Aorta aneurysm with Sever aortic Regurgitation is Bentall surgery but in some selected cases this complex surgery was not performed with different reason like advanced age and coexisting comorbidity involving renal and hepatic and lung Function. In our cases 75 years old man with chronic renal failure ( Cr= 3.2 ) who was known ...

The acute and chronic effect of cigarette smoking on the elastic properties of the ascending aorta in healthy male subjects.

INTRODUCTION Aortic elastic properties are markers and prognosticators of cardiovascular risk. Smoking adversely affects arterial elastic properties. The acute and chronic effect of cigarette smoking on the elastic properties of the ascending aorta has not been determined. METHODS The chronic part of the study included 130 healthy male subjects (age 38.1+/-8.9 years, 85 smokers and 45 non-smo...

Arterial Distensibility in Chronic Inflammatory Rheumatic Disorders

The pulse wave velocity (PWV), as an indicator of arterial distensibility, may play an important role in the stratification of patients based on the cardiovascular risk. PWV inversely correlates with arterial distensibility and relative arterial compliance. Decreased arterial distensibility alters arterial blood pressure and flow dynamics, and disturbes coronary perfusion. Systemic immune and i...

Chronic reduction of nitric oxide level in adult spontaneously hypertensive rats induces aortic stiffness similar to old spontaneously hypertensive rats.

INTRODUCTION Age and hypertension are two major determinants of arterial stiffness, as well as endothelial dysfunction. The present study was designed to test whether a chronic reduction of endogenous nitric oxide (NO) produces arterial stiffening close to that observed in old spontaneously hypertensive rats (SHR), and also to study the effect of an acute or a chronic decrease in blood pressure...
