The object of this study was to evaluate the contribution of carotid distensibilty on baroreflex sensitivity in patients with type 2 diabetes mellitus with at least 2 additional cardiovascular risk factors. Carotid distensibility was measured bilaterally at the common carotid artery in 79 consecutive diabetic patients and 60 matched subjects without diabetes. Spontaneous baroreflex sensitivity ...
Distensibility and Strength of the Pelvic Floor Muscles of Women in the Third Trimester of Pregnancy
OBJECTIVE The objective of this study was to compare the role of the pelvic floor muscles between nulliparous and multiparous women in the third trimester of pregnancy, by analyzing the relationship between electrical activity (surface electromyography-EMG), vaginal palpation (modified Oxford scale), and perineal distensibility (Epi-no). METHODS This was an observational cross-sectional study...
The reason for the particularly increased risk for cardiovascular complications in diabetic women is still unclear. We have previously found decreased distensibility of elastic arteries in type I diabetic women, indicating increased cardiac load, not seen in type I diabetic men, which might be one contributing factor. Whether the effect of gender is different in muscular arteries in type I diab...
Background: Changes in the properties of large arteries correlate with higher cardiovascular risk. Recent guidelines have included the assessment of those properties to detect subclinical disease. Establishing reference values for the assessment methods as well as determinants of the arterial parameters and their correlations in healthy individuals is important to stratify patients. Objective: ...
OBJECTIVES Aortic arch reconstruction in children with single ventricle lesions may predispose to circulatory inefficiency and maladaptive physiology leading to increased myocardial workload. We sought to describe neoaortic anatomy and physiology, risk factors for abnormalities, and impact on right ventricular function in patients with single right ventricle lesions after arch reconstruction. ...
Pregnancy-associated increases in uterine artery (UA) blood flow are due, in part, to vasoactive and growth-related changes that enlarge UA diameter. Although active and passive mechanical factors can contribute to this enlargement, their role is less well understood. We hypothesized that pregnancy increased UA distensibility and/or decreased myogenic tone. Given the fetal growth restriction an...
BACKGROUND Vitamin D has been associated with multiple cardiometabolic risk factors in children but there is a paucity of studies examining its correlation to vascular function and structure. Our objective was to determine whether there is a correlation between vitamin D, cardiometabolic risk, vascular distensibility and carotid artery intima-media thickness (CIMT) in high-risk children. MATE...
Several recent results obtained in hypertensive animals and subjects under in vivo isobaric conditions do not confirm the classic view of stiffer arteries in hypertensive subjects. We compared the mechanical behavior of in situ isolated common carotid arteries from normotensive Wistar-Kyoto rats (WKY) and age-matched spontaneously hypertensive rats (SHR) under both static and dynamic conditions...
BACKGROUND Monocyte to high density lipoprotein cholesterol ratio (MHR) is generally understood to be a candidate marker of inflammation and oxidative stress. Therefore, we aimed to assess the association between MHR and aortic elastic properties in hypertensive patients. METHODS A total of 114 newly-diagnosed untreated patients with hypertension and 71 healthy subjects were enrolled. Aortic ...
OBJECTIVES Mechanical and structural characteristics of vulnerable plaques were evaluated using coronary angioscopy and intravascular ultrasound. BACKGROUND Mechanical stress and composition of plaques play an important role in plaque disruption. METHODS Thirty-eight lesions in 38 patients were examined pre-interventionally. The plaques were classified as either yellow or white using corona...
