Acute inferior myocardial infarction due to a large thrombus in the Left coronary sinus of valsalva.

2021

Background Masses in the ascending aorta are an uncommon source of coronary embolism: thrombi located on atherosclerotic aortic plaques are the most frequent cause. A floating thrombus, without evidence of ascending aortic pathology has rarely been reported Method We report a case of an unusual aortic route thromboembolism leading ST segment elevation Myocardial Infarction (STEMI). The patient was referred to the Hub Hospital to undergo urgent coronarography. The examination excluded atherosclerotic coronary arteries disease but an unusual persistence of contrast dye was found at the level of non-coronary sinus. The trans-esophageal echocardiography showed a mobile pedunculated echogenic ma…

Pheochromocytoma in the Pediatric Age Group: The Prostate—An Unusual Location

1990

AbstractPheochromocytomas of the prostate are rare, with only 3 cases in adults reported in the literature. We present the case of an 8-year-old boy with a pheochromocytoma of the prostate and a second tumor in the region of the left internal iliac artery. (J. Urol., 144: 1219–1221, 1990)

Actions of alpha-adrenoceptor blocking agents on two types of intracellular calcium stores mobilized by noradrenaline in rat aorta.

1993

In isolated rat aortic strips noradrenaline induces a biphasic contractile response in Ca-free medium, associated with two different intracellular calcium pools, one of which is common to caffeine. We analyzed the mechanisms involved in the depletion and repletion of both intracellular Ca pools sensitive to noradrenaline in different experimental procedures in presence of prazosin, phentolamine and yohimbine. At 37 degrees C the alpha-adrenergic blocking agents inhibited contractile responses to noradrenaline in Ca-free medium, with prazosin being highly selective. alpha 2-adrenoceptors probably do not participate in the release of Ca from internal stores, as no contractile response was obs…

Quality-of-Life and Economic Outcomes of Assessing Fractional Flow Reserve With Computed Tomography Angiography: PLATFORM.

2015

International audience; BACKGROUND: Fractional flow reserve estimated using computed tomography (FFRCT) might improve evaluation of patients with chest pain. OBJECTIVES: The authors sought to determine the effect on cost and quality of life (QOL) of using FFRCT instead of usual care to evaluate stable patients with symptoms suspicious for coronary disease. METHODS: Symptomatic patients without known coronary disease were enrolled into 2 strata based on whether invasive or noninvasive diagnostic testing was planned. In each stratum, consecutive observational cohorts were evaluated with either usual care or FFRCT. The number of diagnostic tests, invasive procedures, hospitalizations, and medi…

Basal Cerebral Computed Tomography as Diagnostic Tool to Improve Patient Selection in Asymptomatic Carotid Artery Stenosis

2012

One-hundred patients were included to evaluate the role of cerebral computed tomography (CT) to improve patient selection in asymptomatic internal carotid stenosis. Symptomatic patients were assigned to group A, asymptomatic patients to group B. A cerebral CT pattern A was observed in groups A and B in 60% and 20%, respectively ( P < .0001). Between A and B groups, type 6 plaques were found, respectively, in 26.7% and 7.5% of patients ( P = .01); a type 5 in 51.7% and 45% ( P = .32) of patients; and a type 4 in 21.7% and 47.5% of patients, respectively ( P = .006). Within B group, the association of CT pattern A and histological plaque level 4, 5, and 6 was, respectively, 25% ( P = .15)…

Cardiovascular dysfunction and vitamin D status in childhood acute lymphoblastic leukemia survivors

2018

Vitamin D (25-OHD) has a role in bone health after treatment for cancer. 25-OHD deficiency has been associated with risk factors for cardiovascular disease, but no data focusing on this topic in childhood cancer survivors have been published. We investigated the 25-OHD status in children treated for acute lymphoblastic leukemia (ALL), and evaluated its influence on vascular function. 25-OHD levels were evaluated in 52 ALL survivors and 40 matched healthy controls. Patients were grouped according to 25-OHD level (< 20 ng/m or ≥ 20 ng/ml). Auxological parameters, biochemical and hemostatic markers of endothelial function (AD, HMW-AD, ET-1, vWFAg, TAT, D-dimers, Fbg, and hs-CRP), ultrasound ma…

Color Doppler Imaging of the Ocular Ischemic Syndrome

1992

Purpose: This study describes hemodynamic characteristics of the ophthalmic, central retinal, and posterior ciliary arteries in 16 eyes of 11 patients with the ocular ischemic syndrome. Understanding the hemodynamic characteristics of the retrobulbar circulation may elucidate the natural history and pathophysiology of the ocular ischemic syndrome and perhaps form the basis for rational treatment of this condition. Methods: Color Doppler imaging, a procedure that permits rapid noninvasive imaging of the ophthalmic, central retinal, and posterior ciliary arteries, was used to quantitate peak systolic blood flow velocities and vascular resistance (pulsatility index) within these vessels in stu…

Orthostatic changes in blood pressure and mortality in the elderly: The Pro.V.A study

2015

BACKGROUND An extensive, albeit contrasting literature has suggested a possible role for orthostatic hypotension as a risk factor for cardiovascular (CVD) and non-CVD mortality, while no data are available for orthostatic hypertension. We investigated whether orthostatic changes in blood pressure (BP) were associated with any increased risk of all-cause, CVD or non-CVD mortality in a group of elderly people. METHODS Two thousand seven hundred and eighty six community-dwelling older participants were followed for 4.4 years. Participants were grouped according to whether they had a drop ≤20mm Hg in systolic, or ≤10mm Hg in diastolic BP (orthostatic hypotension), an increase in mean orthostati…
