Intensive lipid lowering with atorvastatin in patients with coronary artery disease, diabetes, and chronic kidney disease

2008

To investigate the effect of intensive lipid lowering with high-dose atorvastatin on the incidence of major cardiovascular events compared with low-dose atorvastatin in patients with coronary artery disease and type 2 diabetes, with and without chronic kidney disease (CKD). Following 8 weeks' open-label therapy with atorvastatin (10 mg/d), 10,001 patients with coronary artery disease were randomized to receive double-blind therapy with either 80 mg/d or 10 mg/d of atorvastatin between July 1, 1998, and December 31, 1999. Of 1501 patients with diabetes, renal data were available for 1431. Patients with CKD were defined as having a baseline estimated glomerular filtration rate (eGFR) below 60…

nrCBF and EEG Monitoring During Probatory Balloon Occlusion of the Internal Carotid Artery

1985

Surgical treatment of tumors in the neck and throat rounding the carotid artery or of giant aneurysms originating from this vessel often makes ligation or resection of the internal carotid artery necessary. This procedure carries a 15%–30% morbidity from cerebral ischemia according to the literature (2, 7).

Possible Adverse Effects of Hyperventilation on rCBF during the Acute Phase of Total Proximal Occlusion of a Main Cerebral Artery

1969

Recent studies seem to favor a beneficial effect of hyperventilation (HV) in cases of cerebrovascular occlusion [1, 4] and brain trauma [2, 5]. On the other hand, it seems that, at least under certain circumstances, HV may exert an adverse effect upon cerebral blood flow and metabolism [3]. Since this question is not settled yet, it seems worthwhile to report briefly the present case of reversible total occlusion of the middle cerebral artery closely followed by successive rCBF studies (133Xe-gamma-clearance method), in which, during the acute phase, HV caused a latent ischemia to become manifest.

Cessation of Cerebral Blood Flow in Total Irreversible Loss of Brain Function

1969

After the demonstration, by our group [3, 4], that in cases of so-called “cerebral death” there is an absence of clearance from the brain of 133Xe selectively injected into the internal carotid artery, further attention was dedicated to establish possible sources of error in this technique.

Combining Body Mass Index With Measures of Central Obesity in the Assessment of Mortality in Subjects With Coronary Disease

2013

Objectives This study sought to assess the mortality risk of patients with coronary artery disease (CAD) based on a combination of body mass index (BMI) and measures of central obesity. Background In CAD patients, mortality has been reported to vary inversely with BMI (“obesity paradox”). In contrast, central obesity is directly associated with mortality. Because of this bi-directional relationship, we hypothesized that CAD patients with normal BMI but with central obesity would have worse survival compared with subjects with other combinations of BMI and central adiposity. Methods We included 15,547 participants with CAD who took part in 5 studies from 3 continents. Multivariate stratified…

Glycaemic variability using continuous glucose monitoring and endothelial function in the metabolic syndrome and in Type 2 diabetes

2010

Diabet. Med. 27, 872–878 (2010) Abstract Aims  Subjects who are at increased risk of developing diabetes may have increased glycaemic variability associated with endothelial dysfunction and possibly subclinical atherosclerosis, which may lead to increased cardiovascular risk observed at the time of diabetes diagnosis. To investigate this hypothesis, we measured endothelial function, carotid intima-media thickness and glycaemic variability using 48-h continuous subcutaneous glucose monitoring in 3 groups of overweight or obese subjects – those without the metabolic syndrome, and those with the metabolic syndrome with or without newly diagnosed Type 2 diabetes. Methods  Consecutive subjects, …

Inferior mesenteric vein as initial landmark for laparoscopic medial to lateral dissection of descending colon - a video vignette

2017

The root of the inferior mesenteric artery is an important area where autonomic nerves are close by, the dissection can be hard and laborious in order to avoid nerve damage; and the separation of mesocolon and retroperitoneum in this area can sometimes be difficult. The inferior mesenteric vein dissection is an alternative option as the first step during medial to lateral approach of laparoscopic left mesocolon mobilisation, as we have shown in this video based on two real cases and two anatomical cadaveric dissection.

Lower Extremity Artery Disease as a Predictor of Coronary Artery Disease

2021

Abstract Coronary artery disease (CAD) is an important determinant of long-term outcome in patients with lower extremity artery disease (LEAD). In this study we evaluated the CAD prevalence among LEAD patients and the association of LEAD lesions location with the CAD presence and severity. 203 patients with LEAD, referred for peripheral and simultaneous coronary angiography, were evaluated. LEAD and CAD were considered angiographically significant for stenosis higher than 50% of arterial lumen. More than two-thirds of LEAD patients had significant CAD, half of them having multi-vessel CAD and a quarter single CAD. Infrapoplitheal arterial lesions seemed to be the strongest predictor of CAD …

Interventional and surgical modalities of treatment for pulmonary arterial hypertension

2004

AbstractBeyond medical therapy, different interventional and surgical approaches exist for treatment of pulmonary arterial hypertension (PAH). Atrial septostomy has been applied in patients with lack of response to medical therapy in the absence of other surgical treatment options. With growing experience, procedure-related death rates have been reduced to 5.4%, and the most suitable patient group has been identified among patients with a mean right atrial pressure between 10 and 20 mm Hg. Pulmonary endarterectomy is the accepted form of treatment for patients with chronic thromboembolic pulmonary hypertension. Establishing the diagnosis and the classification of the type of lesions by pulm…
