OBJECTIVES: Prehypertension, which may be the precursor of hypertension, is an important public health problem in the community. Myocardial performance index (MPI) is a noninvasive Doppler measurement of global ventricular function. Thus, our aim was to evaluate left ventricule (LV) functions with the MPI in prehypertensive patients with normal coronary artery angiography. PATIENTS AND MATERIALS: Forty prehypertensive patients (21 women and 19 men), with blood pressures between 120/80 and 139/89 mmHg, and 40 normotensive controls (18 women and 22 men), with blood pressures under 120/80 mmHg, were included in the study...

OBJECTIVE: Pulmonary hypertension (PH) is caused by etiologies that differ in pathophysiology. Patients with undiagnosed PH may have a computed tomography pulmonary angiography (CTPA) scan during workup. Static measurements on computed tomography correlate with PH; however, dynamic parameters have received less attention. We studied the correlation between CTPA dynamic parameters and PH and assessed whether these parameters differ among PH etiologies. We also propose a method for PH screening...

Changes in cerebral blood flow (CBF) may occur with acute exposure to high altitude; however, the CBF of the brain parenchyma has not been studied to date. In this study, identical magnetic resonance scans using arterial spin labeling (ASL) were performed to study the haemodynamic changes at both sea level and high altitude. We found that with acute exposure to high altitude, the CBF in acute mountain sickness (AMS) subjects was higher (P < 0.05), while the CBF of non-AMS subjects was lower (P > 0...

OBJECTIVE: Both the spot signs, which is a bright spot on computed tomography angiography (CTA) source images, and hypodensity areas within a hematoma on precontrast CT scans, which presumably represent uncoagulated blood, have been reported to be predictive of hematoma enlargement in acute spontaneous intracerebral hematoma (ICH). The aim was to investigate densities on precontrast CT scans in an area within a hematoma that matched the locations of spot signs on CTA source images. METHODS: In consecutive cases of spontaneous ICH admitted within 6 h after onset, early spot signs on CTA source images and delayed spot signs on delayed-phase CT scans 90 s after CTA were evaluated...

Dieulafoy's lesions of the Jejunum are extremely rare. Therefore, localization of lesions is very difficult due to their small size and tendency of occasional bleeding. However, it is important to mention the location of the Dieulafoy's lesions to prevent excessive intestinal resections or, even worse, resection of the normal intestine. We report a case of preoperative localization of a Dieulafoy's lesion embolized by a metallic coil that allows a surgeon to accurately identify the bleeding, permitting a minimally invasive surgical treatment...

Intracavernous internal carotid artery (ICICA) aneurysm secondary to pituitary infection is exceedingly rare. We report an unusual case of a 63-year-old man who presented with acute left blepharoptosis and imaging findings of a pituitary infection. Interestingly, sudden onset of right blepharoptosis occurred after anti-infective therapy for ten days. Digital subtraction angiography revealed a right ICICA aneurysm. After six months of follow-up visits, enlargement of the ICICA aneurysm was observed, and the endovascular technique of a low-profile visualized intraluminal support (LVIS) stent combined with five detachable coils was successfully performed to treat the ICICA aneurysm with preservation of the internal carotid artery...

BACKGROUND: Given both lipoprotein (Lp)(a) and vitamin D have been found to be associated with coronary heart disease (CHD) risk and a biochemical link between vitamin D and cholesterol on atherosclerosis has been proposed, we hypothesised there could exist an interaction between Lp(a) and vitamin D on the severity of CHD. METHODS: Lp(a) and 25-OH vitamin D were measured in the plasma of 348 consecutive patients (mean age 62.4±10.5 years; 56.3% male) undergoing coronary angiography at our Heart Center...

REVIEW
Valérie Wolff, Emilie Jouanjus
It is critically important to identify all factors that may play a role in the recent increase of the incidence of stroke among the young population. Considering the worldwide use of cannabinoids (cannabis and synthetic cannabinoids), the recent legalization of their consumption in some countries, and their supposed involvement in cardiovascular events, we evaluated their role in the occurrence of neurovascular complications among the young. Ninety-eight patients were described in the literature as having a cannabinoids-related stroke (85 after cannabis use and 13 after synthetic cannabinoids)...
