Long-term clinical and angiographic outcomes of diabetic patients after revascularization with early generation drug-eluting stents

Early generation drug-eluting stents (DESs) reduce restenosis and repeat revascularization procedures. However, the long-term safety and efficacy of early generation DES according to diabetic status are poorly established.

Stent thrombosis with drug-eluting and bare-metal stents: evidence from a comprehensive network meta-analysis

The relative safety of drug-eluting stents and bare-metal stents, especially with respect to stent thrombosis, continues to be debated. In view of the overall low frequency of stent thrombosis, large sample sizes are needed to accurately estimate treatment differences between stents. We compared the risk of thrombosis between bare-metal and drug-eluting stents.

Long-term vascular healing in response to sirolimus- and paclitaxel-eluting stents: an optical coherence tomography study

This study sought to assess stent strut coverage, malapposition, protrusion, and coronary evaginations as markers of healing 5 years after implantation of sirolimus-eluting stents (SES) and paclitaxel-eluting stents (PES), by optical coherence tomography (OCT).

Effect of biolimus-eluting stents with biodegradable polymer vs bare-metal stents on cardiovascular events among patients with acute myocardial infarction: the COMFORTABLE AMI randomized trial

The efficacy and safety of drug-eluting stents compared with bare-metal stents remains controversial in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI).

Peri-interventional antibiotic prophylaxis only vs continuous low-dose antibiotic treatment in patients with JJ stents: a prospective randomised trial analysing the effect on urinary tract infections and stent-related symptoms

To evaluate the antibiotic treatment regime in patients with indwelling JJ stents, the benefits and disadvantages of a peri-interventional antibiotic prophylaxis were compared with those of a continuous low-dose antibiotic treatment in a prospective randomised trial.

Impact of atrial fibrillation on clinical outcomes among patients with coronary artery disease undergoing revascularisation with drug-eluting stents

Coronary artery disease (CAD) and atrial fibrillation (AF) are major determinants of morbidity and mortality. A combined treatment with antiplatelet agents and vitamin K antagonists limits the risk of stent thrombosis and stroke while increasing the rate of bleeding. The objective of this study was to investigate the impact of atrial fibrillation (AF) on long-term clinical outcomes in patients with CAD undergoing percutaneous coronary intervention (PCI) with drug-eluting stents (DES).

Sirolimus-eluting coronary stents in small vessels

BACKGROUND: This prospective multicenter study compared angiographic in-lesion late lumen loss in de novo native coronary artery lesions (vessel diameter range 2.25-2.75 mm, length range > or = 15 to < or = 30 mm) 8 months after the implantation of a sirolimus-eluting stent with that of similar vessels with the same drug-eluting stent or a bare stent of the SIRIUS study (historical controls). METHODS AND RESULTS: One hundred one patients (study group) were matched and compared with 323 patients receiving the bare stent (bare control group) and with 350 receiving the Cypher stent (Cypher control group) in the SIRIUS trial. Mean in-lesion late loss in the study group was lower than that in the bare control group (0.20 versus 0.76 mm, P < .0001) and not inferior to that in the Cypher control group (0.27 mm, P = .3). Adverse event rates (death and myocardial infarction) were similar between groups. At 8 months, target lesion revascularization rates were 0% in the study group, 13.2% in the bare control group (P < .001), and 4.6% in the Cypher control group (P = .03). CONCLUSIONS: The Cypher Bx Velocity stent was confirmed to be superior to the bare Bx Velocity stent in small coronary vessels in terms of in-lesion late loss 8 months after implantation.

Efficacy of drug eluting stents in patients with and without diabetes mellitus: indirect comparison of controlled trials

To examine whether polymer based coronary stents eluting sirolimus or paclitaxel are equally effective in patients with and without diabetes.

ESPEN Guidelines on Enteral Nutrition: Geriatrics

Nutritional intake is often compromised in elderly, multimorbid patients. Enteral nutrition (EN) by means of oral nutritional supplements (ONS) and tube feeding (TF) offers the possibility to increase or to insure nutrient intake in case of insufficient oral food intake. The present guideline is intended to give evidence-based recommendations for the use of ONS and TF in geriatric patients. It was developed by an interdisciplinary expert group in accordance with officially accepted standards and is based on all relevant publications since 1985. The guideline was discussed and accepted in a consensus conference. EN by means of ONS is recommended for geriatric patients at nutritional risk, in case of multimorbidity and frailty, and following orthopaedic-surgical procedures. In elderly people at risk of undernutrition ONS improve nutritional status and reduce mortality. After orthopaedic-surgery ONS reduce unfavourable outcome. TF is clearly indicated in patients with neurologic dysphagia. In contrast, TF is not indicated in final disease states, including final dementia, and in order to facilitate patient care. Altogether, it is strongly recommended not to wait until severe undernutrition has developed, but to start EN therapy early, as soon as a nutritional risk becomes apparent.

Periprocedural and late consequences of overlapping Cypher sirolimus-eluting stents: pooled analysis of five clinical trials

OBJECTIVES: The purpose of this research was to determine the relative safety and efficacy of multiple (> or =2) overlapping Cypher sirolimus-eluting stents (SES) (Johnson ; Johnson, New Brunswick, New Jersey). BACKGROUND: Overlapping coronary stents are common. The periprocedural and late clinical and angiographic consequences of overlapped coronary stents are not clearly defined, particularly for drug-eluting stents. METHODS: All patients enrolled into five clinical trials of the SES were analyzed. Three of these trials were prospective randomized comparisons of the SES to the bare-metal stent (BMS), and two were prospective non-randomized trials of SES-treated patients with historical controls. All clinical and angiographic outcomes in overlap-stent-treated patients were compared by stent type and with single-stent-treated patients for the same stent device. RESULTS: In all, 575 patients with stent overlap (337 SES, 238 BMS) and 1,162 patients with single stents (697 SES, 465 BMS) were analyzed. Stent overlap was associated with a greater late lumen loss in stent and more frequent angiographic restenosis regardless of stent type. Among overlap-stent-treated patients, the SES provided similar magnitude of restenosis benefit as observed for single-stent-treated patients. Overlapped SES was not associated with an increase in myocardial infarction. CONCLUSIONS: The strategy of SES overlap, when required, is both safe and efficacious in reducing restenosis with no increase in the incidence of myocardial infarction or major adverse cardiovascular events, when compared with a bare metal coronary stent prosthesis.
