Diastolic dysfunction and computed tomography.
c s w d Left ventricular (LV) diastolic dysfunction is being increasingly recognized as a marker of risk both in ischemic and nonischemic cardiomyopathies. In fact, the syndrome of congestive heart failure, classically considered a hallmark of systolic dysfunction, can be completely dependent on diastolic dysfunction of the LV (1), and its long-term prognosis is similarly poor. In the natural h...
متن کاملCoronary endothelial dysfunction and non-contrast multidetector computed tomography.
Previous authors have evaluated endothelial dysfunction after intracoronary infusion of acetylcholine by Doppler flow wire (coronary blood flow) or invasive coronary angiography (coronary artery vasodilation).4–6 More recent reports have shown that non-invasive assessment of myocardial blood flow (MBF) by positron emission tomography (PET) can effectively evaluate coronary endothelial dysfuncti...
متن کامل[Diastolic dysfunction and diastolic heart failure].
There are frequent clinical Cases in Cardiological practice when cardiac failure develops together with normal systolic function of left ventricle. In these patients after revealing the diastolic dysfunction the heart diastolic failure is diagnosed, but in frequent cases this diagnosis is based on exclusion method. According to Framingham data the number of patients with clinically manifested d...
متن کاملDiastolic dysfunction.
Diastolic dysfunction of the heart is characterized by normal left ventricular contractility and normal ejection fraction, however ventricular relaxation is impaired. In systolic dysfunction, ventricular contractility and ejection fraction are reduced, in addition to impaired relaxation. The prevalence of diastolic dysfunction is increased in the elderly, especially those who have had inadequat...
متن کاملCorrelation Between Tissue Densities in Computed Tomography and Three Different Cone-Beam Computed Tomography Units (In Vitro)
Background and Aim: Bone density is of great assistance in the selection of the proper implant site. The present study aimed to assess the correlation between tissue densities in computed tomography (CT) and three different cone-beam computed tomography (CBCT) units. Materials and Methods: In this descriptive study, a radiographic phantom consisting of a transparent polymethyl methacrylate (PM...
