Calcification of the heart and great vessels is secondary to those diseases which cause a significant alteration of tissue matrix. Metabolic derangements can cause microscopic calcification of heart muscle, but this has not been demonstrated conclusively roentgenographically. The deposition of calcium may...
Color Doppler echocardiography has limitations, particularly in the assessment of valvular regurgitation and pericardial diseases. MRI, with the help of th... Didier,D. - 《Journal De Radiologie》 被引量: 7发表: 2004年 Calcification of the heart, vessels and kidneys in experimental magnesium defic...
Calcification of the heart and vessels in fetuses is a rare condition. It may be dystrophic or metastatic. An extremely rare form of vascular calcification has been termed 'idiopathic arterial calcification of infancy', which is inherited in an autosomal recessive pattern. We report four cases ...
Calcification of non-osseous tissues such as heart valves or vessels is a major concern in clinical practice. The exact mechanism is still unknown. Numerous studies have shown that mineral deposits of crystalline hydroxyapatite within these tissues were associated with increased non-collagenous protein ...
A recent study reports that coronary artery calcification (CAC) predicts the risk of heart failure, myocardial infarction and stroke in patients with moderate chronic kidney disease (CKD). This finding suggests that even in CKD, CAC is a marker of cardiovascular risk rather than a benign indicator...
4.6). This has been shown to be composed of a leash of blood vessels (Masamed et al., 2009; Sharath Kumar et al., 2010). Nodular or thin-walled ring enhancement patterns are seen in up to 70% of the lesions (see Fig. 4.6) (Ramsey and Gean, 1997). The lesion load, the ...
(24)showed that among 1,461 patients undergoing coronary angiography, those with coronary calcium in more than one vessel by EBT were 2.2 times more likely to suffer a cardiovascular event than subjects with no calcified vessels. Several additional reports of asymptomatic patients have also indicated...
The effectiveness of the compounds in arresting renal calcificationin vivo was also studied using well ... MR Brown 被引量: 0发表: 1984年 Silicon in the Blood and Calcification of the Arteries. Attention is first drawn to atheroma of the arteries in which the aorta and coronary vessels are ...
Fluoroscopy did not detect 8 of 19 patients with a stenosis ≥ 75 % (1 vessel: n = 1; 2 vessels: n = 3; 3 vessels: n = 4). In spiral CT sensitivity was 100 % and specificity was 33 % (FS: 58 and 48 %). Positive predictive value was 83 % for spiral CT (FS: 50 %), ...
Matrix Gla protein (MGP) is a VKDP which in its active form, the carboxylated and phosphorylated MGP (cMGP), has the potential to inhibit vascular calcification. Thus, whereas cMGP is found in healthy vessels, the inactive form, dephosphorylated uncarboxylated MGP (dp-ucMGP) accumulates in ...
