Simulation of bempedoic acid and ezetimibe in the lipid-lowering treatment pathway in Austria using the contemporary SANTORINI cohort of high and very high risk patients.

Objective: The low-density lipoprotein cholesterol goals in the 2019 European Society of Cardiology/European Atherosclerosis Society dyslipidaemia guidelines necessitate greater use of combination therapies. We describe a real-world cohort of patients in Austria and simulate the addition of oral bempedoic acid and ezetimibe to estimate the proportion of patients reaching goals.

Methods: Patients at high or very high cardiovascular risk on lipid-lowering treatments (excluding proprotein convertase subtilisin/kexin type 9 inhibitors) from the Austrian cohort of the observational SANTORINI study were included using specific criteria.

Influence and interaction of diabetes and lipoprotein (a) serum levels on mortality of patients with peripheral artery disease.

Background: Diabetes mellitus is a risk factor for early complications and mortality in patients with peripheral artery disease. Lipoprotein (a) [Lp(a)] is also suggested to be a marker of increased cardiovascular risk. We investigated the association and interaction between diabetes mellitus, lipoprotein(a) and mortality in high risk patients with peripheral artery disease (PAD).

Simvastatin reduces serum level of vascular endothelial growth factor in hypercholesterolemic patients.

Vascular endothelial growth factor plays a pivotal role in the progression of atherosclerotic lesions and causes instability of atherosclerotic plaques by inducing neoangiogenesis inside the current plaque. The pro-inflammatory cytokine interleukin (IL-) 6 induces vascular endothelial growth factor in smooth muscle cells (SMC). HMG-CoA reductase inhibitors (statins), display beside their lipid-lowering potency various pleiotropic effects.

Insulin, C-peptide, and restenosis after femoral artery balloon angioplasty in type II diabetic and nondiabetic patients.

Purpose: Endogenous and exogenous insulin is suggested to stimulate hypertrophic wound-healing responses and therefore may promote neointimal hyperplasia and restenosis after balloon angioplasty. The ratio of C-peptide to insulin reflects endogenous insulin secretion. In diabetic patients with insulin substitution, lower ratios display a higher proportion of exogenous insulin.

Effect of nimodipine on ocular blood flow and colour contrast sensitivity in patients with normal tension glaucoma.

Aim: To investigate the effects of oral nimodipine on ocular haemodynamic parameters and colour contrast sensitivity in patients with normal tension glaucoma (NTG).

Design: The study was performed in a randomised, placebo controlled, double masked, crossover design.

Participants: Nimodipine (60 mg) or placebo was administered to 14 consecutive NTG patients.

Low level laser therapy for treatment of primary and secondary Raynaud's phenomenon.

Background: We recently performed a pilot study which suggested that clinical and thermographic improvements occurred in patients with primary and secondary Raynaud's phenomenon (RP) following treatment with low level laser irradiation (LLLI). In view of these findings, we have proceeded with a double blind, placebo-controlled study.

Methods: Forty seven patients suffering from primary or secondary RP were randomly assigned in a double-blind manner to receive either 10 sessions of distant LLLI (16 f, 8 m, median age 45 years) or placebo irradiation (21 f, 2 m, median age 46 years) during winter months.

Fibrinogen predicts mortality in high risk patients with peripheral artery disease.

Objective: Fibrinogen plays a key role in the pathogenesis of atherosclerosis and complications of atherothrombotic disease. We investigated the prognostic impact of fibrinogen levels on mortality of high risk patients with peripheral artery disease (PAD).

Methods: We studied 486 patients with PAD and several cardiovascular comorbidities.

Flow monitoring: performance characteristics of ultrasound dilution versus color Doppler ultrasound compared with fistulography.

Background: Measurement of access blood flow is the preferred noninvasive screening test for hemodialysis arteriovenous (AV) fistula stenosis. However, performance characteristics of the 2 most frequently used ultrasound techniques compared with fistulography remain elusive.

Methods: We evaluated 59 hemodialysis patients with native forearm AV fistulae who underwent all 3 measurements in a prospective order: the ultrasound dilution technique (UDT), color Doppler ultrasonography (CDUS), and fistulography.

Simvastatin reduces the expression of adhesion molecules in circulating monocytes from hypercholesterolemic patients.

Objective: The intercellular adhesion molecule-1 (ICAM-1/CD54) and its ligand, CD11a/CD18, mediate endothelial adhesion of leukocytes and their consecutive transmigration. Anti-inflammatory effects of statins are considered to be exerted in part through inhibition of leukocyte-endothelial interactions. We investigated the in vivo effects of simvastatin treatment in hypercholesterolemic patients and the influence of various statins on expression of cellular adhesion molecules in vitro.

Outcome of conservative medical treatment of patients with infrarenal abdominal aortic aneurysms.

Objective: Since non-invasive diagnostic methods have become available and screening programs have become popular, abdominal aortic aneurysms are more frequently being detected at an early stage of the disease. We analyzed the course of conservatively treated patients with infrarenal abdominal aortic aneurysms (AAA), and determined independent risk factors for aneurysm expansion.

Methods: The study was designed as a retrospective-cohort study including 110 consecutive patients with AAA.

Monitoring of antiplatelet therapy with the PFA-100 in peripheral angioplasty patients.

Background: In patients suffering from peripheral arterial occlusive disease (PAOD) the risk of restenosis after percutaneous transluminal angioplasty (PTA) might be influenced by platelet mediated factors.

Objective: To look for a correlation between the effect of antiplatelet therapy and recurrence of disease after PTA by monitoring platelet function in 3-month intervals by the platelet function analyzer system, PFA-100, over a period of 1 year.

Patients And Methods: A group of 98 patients (43 females, 55 males) with PAOD, treated with aspirin (n = 52), thienopyridine (n = 34) or combination therapy of both (n = 12) were followed over a period of 12 months after elective PTA of the lower extremities with regard to occurrence of restenosis or reocclusion at the site of angioplasty, to demonstrate inhibitory effects on platelets, induced by antiplatelet therapy.

Predictors of long-term results after treatment of iliac artery obliteration by transluminal angioplasty and stent deployment.

Purpose: To investigate initial and long-term success rate after percutaneous treatment of iliac artery occlusion with angioplasty and stent deployment. To investigate the influence of vascular comorbidity, lesion length, stent placement and lesion coverage as possible predictors of outcome.

Methods: Between January 1994 and December 1999, 80 iliac recanalizations were performed on 78 patients, median age 61.

Relation of small artery compliance and lipoprotein (a) in patients with atherosclerosis.

Background: Lipoprotein (a) is suggested to cause endothelial dysfunction, alteration of elastic arterial properties, and decreased arterial compliance. We investigated the relation of arterial compliance and lipoprotein (a) serum [Lp(a)] levels in patients with atherosclerosis.

Methods: Prospective study included 118 consecutive patients with atherosclerosis.

Objective: To analyse the clinical outcome of patients with ischaemic ulcers (Fontaine stage IV) undergoing percutaneous transluminal angioplasty (PTA).

Methods And Design: Retrospective cohort study of 40 patients (21 males) treated between January 1998 and December 1998. Cardiovascular risk factors, co-morbid, baseline laboratory, angiographic data and technical success were recorded.

Simvastatin reduces expression of cytokines interleukin-6, interleukin-8, and monocyte chemoattractant protein-1 in circulating monocytes from hypercholesterolemic patients.

Objective: A number of studies have shown that statins decrease morbidity and mortality in patients with cardiovascular diseases. The anti-inflammatory effects of statins have recently been implicated in the clinical benefit that can be obtained in the treatment of atherosclerosis. Little is known about the mechanisms by which statins counteract inflammation.

Homocysteine levels in patients with Raynaud's phenomenon.

Background: Patients with Raynaud's phenomenon (RP) have vasomotor dysregulation, mainly cause by dysfunction of the endothelium. Since homocysteine has been found to be damaging to endothelial cells, we investigated the concentrations of plasma homocysteine, folate and vitamin B12 in patients with primary or secondary RP compared to healthy individuals.

Patients And Methods: We measured the concentrations of plasma fasting homocysteine, folate and vitamin B12 in a group of healthy individuals (n = 45) and in patients with primary (n = 26) or secondary RP (n = 42).

Low level laser treatment of primary and secondary Raynaud's phenomenon.

Background: Patients who had been treated with low level laser (LLL) for their digital ulcers reported an impressive improvement of their symptoms of episodic digital ischaemia. Therefore this pilot study was performed to evaluate the efficacy of LLL as a new non-drug non-invasive treatment for patients with primary and secondary Raynaud's phenomenon (RP).

Patients And Methods: Forty patients (29 female, 11 male, mean age 51 years) with active primary (28%) and secondary (72%) Raynaud's phenomenon received 10 sessions of LLL distant irradiation during winter months.

Post-thrombotic syndrome after primary event of deep venous thrombosis 10 to 20 years ago.

Aims: We investigated the impact of the extent of primary deep venous thrombosis (DVT) and recurrent thrombotic events in accordance to other presumed prognostic factors for long-term clinical outcome after first DVT.

Patients And Methods: All consecutive in-patients, who were treated following first acute DVT between January 1, 1978 and December 31, 1988 at the Department of Angiology were identified by admission lists. Localisation, extent of primary DVT, etiology and concomitant pulmonary embolism (PE) at the time of initial presentation and occurrence of post-thrombotic syndrome (PTS) at follow-up visits were assessed by chart review.

A severe case of vascular thoracic outlet syndrome.

We report a 21-year-old patient who presented at the outpatient department of angiology with incipient necroses in the fingertips of the right hand. Colour-coded duplex sonography and angiography demonstrated occlusion of the right brachial, ulnar and radial arteries, obviously resulting from an embolism from the subclavian artery narrowed by a cervical rib. After partly successful local thrombolysis this accessory rib was resected.

Temporary vena cava filters do not always protect from fatal pulmonary embolism.

We describe the case of a young woman who developed fatal pulmonary embolism during thrombolytic therapy of a deep pelvic and leg vein thrombosis, despite the insertion of a temporary vena cava filter. So the opinion that the insertion of inferior vena cava filters always prevents lethal pulmonary embolism caused by thrombi of the deep vein system must be revised.

Endovascular brachytherapy for prophylaxis of restenosis after femoropopliteal angioplasty : results of a prospective randomized study.

Background: Inasmuch as endovascular brachytherapy (BT) has gained recent interest because of its inhibitory effect on mechanisms leading to restenosis after percutaneous transluminal angioplasty (PTA), we performed this randomized study to determine its efficacy for prophylaxis of restenosis after femoropopliteal PTA.

Methods And Results: One hundred thirteen patients (63 men, 50 women; mean age 71 years) with de novo or recurrent femoropopliteal lesions were included in this randomized trial comparing the restenosis rate after PTA plus BT (57 patients, PTA+BT group) versus PTA (56 patients, PTA group) without stent implantation. The mean treated length was 16.

Intraarterial (192)Ir high-dose-rate brachytherapy for prophylaxis of restenosis after femoropopliteal percutaneous transluminal angioplasty: the prospective randomized Vienna-2-trial radiotherapy parameters and risk factors analysis.

Purpose: The aim of the Vienna-2-trial was to compare the restenosis rate of femoropopliteal arteries after percutaneous transluminal angioplasty (PTA) with or without intraarterial high-dose-rate (HDR) brachytherapy (BT) using an (192)Ir source.

Materials And Methods: A prospective, randomized trial was conducted from 11/96 to 8/98. A total of 113 patients (63 men, 50 women), with a mean age of 71 years (range, 43-89 years) were included.
