Parametric assessment of myocardial perfusion by densitometric evaluation of digital subtraction coronary angiograms: a comparison with tomographic T…

2002

Densitometric results about local myocardial perfusion are compared with those derived from a quantitative analysis of TL-201 single photon emission computer tomograms (TL-201 SPECT). Ten patients underwent conventional TL-201 SPECT at rest and after maximum bicycle stress and dipyridamole infusion the day prior to the investigation. SPECT was applied to provide improved spatial resolution for the detection of perfusion abnormalities. During the catheterization procedure four digital subtraction coronary angiograms were performed, two of the left and two of the right coronary artery both before and after pharmacologically induced hyperemia by intracoronary papaverine. The densitometric para…

CA125 but not NT-proBNP predicts the presence of a congestive intrarenal venous flow in patients with acute heart failure

2021

Abstract Background Intrarenal venous flow (IRVF) measured by Doppler ultrasound has gained interest as a potential surrogate marker of renal congestion and adverse outcomes in heart failure. In this work, we aimed to determine if antigen carbohydrate 125 (CA125) and plasma amino-terminal pro-B-type natriuretic peptide (NT-proBNP) are associated with congestive IRVF patterns (i.e., biphasic and monophasic) in acute heart failure (AHF). Methods and results We prospectively enrolled a consecutive cohort of 70 patients hospitalized for AHF. Renal Doppler ultrasound was assessed within the first 24-h of hospital admission. The mean age of the sample was 73.5 ± 12.3 years; 47.1% were female, and…

The Clinical Relevance of LDL Size and Subclasses Modulation in Patients with Type-2 Diabetes

2007

increasing evidence suggest that the "quality" rather than only the "quantity" of low density lipoproteins (LDL) exerts a great influence on the cardiovascular risk. Hypertriglyceridemia, low HDL-cholesterol and increased levels of small dense LDL characterise diabetic dyslipidemia. in subjects with type-2 diabetes LDL size seems also to represent a good marker of clinical apparent and non-apparent atherosclerosis. Recently, the Coordinating Committee of the National Cholesterol Education Program stated that high-risk patients may benefit of stronger therapeutical approaches, a category of subjects that include those with type-2 diabetes. Screening for the presence of small, dense LDL may p…

The role of fibrate treatment in dyslipidemia: an overview.

2012

Dyslipidemia, and especially atherogenic dyslipidemia, a combination of small low-density lipoproteins cholesterol (LDL-C), decreased high-density lipoprotein cholesterol (HDL-C) and increased triglyceride (TG) concentrations, represents a major cardiovascular (CV) risk factor. Nuclear receptor peroxisome proliferator-activated receptors (PPARs) are involved in the regulation of lipid metabolism; PPAR ligands are used to treat dyslipidemias. Fibrates have a major impact on TG metabolism as well as on modulating LDL size and subclasses. Fibrates target atherogenic dyslipidemia by increasing plasma HDL-C concentrations and decreasing small dense LDL (sdLDL) particles and TGs, thus contributin…

Measurement of coagulation factors during rivaroxaban and apixaban treatment: Results from two crossover trials

2018

Abstract Background Prediction models for venous thromboembolism recurrence will likely be improved by adding levels of coagulation factors. Risk assessment is ideally performed during anticoagulant treatment, however, the influence of direct oral anticoagulants on coagulation factors is uncertain. Objective To assess the influence of rivaroxaban and apixaban on several coagulation factor levels. Methods In two crossover trials we assessed the influence of rivaroxaban and apixaban intake on factor (F)VIII, FXI and FXII‐activity and fibrinogen, von Willebrand factor (VWF:Ag), and d‐dimer levels. At three sessions with a washout period in between, blood was taken from 12 healthy male individu…

Functional Nasal Surgery and Use of CPAP in OSAS Patients: Our Experience.

2018

The surgical correction of nasal obstruction is definitely effective and recommended in patients with poor CPAP compliance, often secondary to the high pressures that need to be given in patients with nasal sub stenosis. For this reason, the objective of this study is the evaluation of the effectiveness and effects of the functional nose surgery on adherence to CPAP- therapy in patients (with moderate to severe OSAS with indication of ventilation therapy) poorly compliant with CPAP. The study was performed on a sample of 52 patients, 40 male and 12 female, aged between 29 and 72 years followed by the Otolaryngology Unit of the University Palermo in the period between January 2015 and Januar…

Effect of insulin on readmission for heart failure following a hospitalization for acute heart failure

2020

AIMS: Type 2 diabetes mellitus (T2DM) is common in patients with heart failure (HF) and is related with worse outcomes. Insulin treatment is associated with sodium and water retention, weight gain, and hypoglycaemia-all pathophysiological mechanisms related to HF decompensation. This study aimed to evaluate the association between insulin treatment and the risk of 1year readmission for HF in patients discharged for acute HF.; METHODS AND RESULTS: We prospectively included 2895 consecutive patients discharged after an episode of acute HF in a single tertiary hospital. Multivariable Cox regression, adapted for competing events, was used to assess the association between insulin treatment and …

Surgical management of ruptured small cerebral aneurysm: Outcome and surgical notes

2015

Background Management of small aneurysms often poses a therapeutic dilemma and surgical treatment or coiling can be considered as therapeutic choices. In the present study, we reviewed our series of ruptured small cerebral aneurysm treated surgically. Methods A total of 53 consecutive patients with ruptured small aneurysm were surgically treated between January 2008 and July 2014. Data were retrospectively collected. Procedure-related death and complications were systematically reviewed. Clinical outcomes were assessed using the Modified Ranking Scale. Neuroradiological follow-up was performed to assess aneurysmal occlusion and recanalization rate. Results The mean aneurysm size was 2 mm ± …
