ABSTRACT

BACKGROUND: The internet has become an easily accessible and widely used source of healthcare information. There are, however, no standardized or commonly accepted criteria for the quality of Obstetrics and Gynecology websites. In this study, we aimed to evaluate the quality of websites of Obstetrics and Gynecology departments in German-speaking countries and to compare websites nationally and internationally. METHODS: We scored 672 websites from Germany (n = 566), Austria (n = 57), and Switzerland (n = 49) using the objective criteria: Google search rank (2 items), technical aspects (11 items), navigation (8 items), and content (6 items) for a 26 point score. Scores were compared nationally and internationally. Multivariable regression models assessed good quality scores (≥50% of maximum) as the dependent variables and country, academic affiliation, being member of a healthcare consortium, confessional affiliation, and content management system (CMS) use as independent variables. RESULTS: The mean score of websites was 13.8 ± 3.3. 4.2% were rated as good (≥75% of maximum), 61.8% as fair (≥50% of maximum). German (14.0 ± 3.2) and Swiss (13.8 ± 4.0) websites scored significantly higher compared to Austrian websites (11.6 ± 2.5) (P < 0.001 and P = 0.005, respectively). Within Germany, academic had higher scores than non-academic departments (14.9 ± 3.2 vs. 13.7 ± 3.1, P < 0.001). Single institutions had higher scores compared to healthcare consortium institutions (14.1 ± 3.2 vs. 13.2 ± 2.6, P = 0.003). Departments in Northern and Southern states had higher scores compared to Eastern states (14.4 ± 3.2 and 14.2 ± 3.2 vs. 13.0 ± 3.0, P < 0.001). In multivariate regression models, all subscores (all: P < 0.001) independently predicted a website's reaching a good quality score, with navigation subscore as strongest predictor. Affiliations were predictors for some good individual subscores, but not for others. High content subscore was associated with good Google search rank, technical aspects, and navigation subscores. CONCLUSIONS: The quality of websites of Obstetrics and Gynecology departments varies widely. We found marked differences depending on country, affiliation, and region.

ABSTRACT

AIMS: Treatment of bare metal in-stent restenosis with the paclitaxel-coated balloon catheter based on the PACCOCATH® technology has yielded superior six-month angiographic and one-year clinical results compared to a paclitaxel-eluting stent. The three-year clinical follow-up is presented. METHODS AND RESULTS: One hundred and thirty-one patients with coronary bare metal in-stent restenosis (>70%, length: <22 mm, vessel diameter: 2.5-3.5 mm) were randomly treated with the paclitaxel-coated balloon (DCB) (3 µg/mm²) or a paclitaxel-eluting stent (DES). Clinical follow-up information was requested from the patients and from their physicians. Quantitative angiographic and demographic baseline data were statistically not different between the groups. Per intention-to-treat analysis at 12 months, the lesion-related rates of major adverse cardiac events were 7.6% and 16.9% (p=0.11) while at 36 months the respective numbers were 9.1% and 18.5% (p=0.14). These differences were primarily due to reduced target lesion revascularisation (TLR) in DCB 4/66 (6.2%) compared to DES patients 10/65 (15.4%) (p=0.10). From 12 to 36 months, 1/65 (1.5%) DCB patients experienced a myocardial infarction while neither TLR nor death occurred in any study patient in either group during that period. CONCLUSIONS: The six-month superiority of the paclitaxel-coated balloon compared to the paclitaxel-eluting stent in the treatment of bare metal coronary in-stent restenosis persisted throughout the three-year clinical follow-up period indicating stability of the lesions treated.

ABSTRACT

AIMS: The one-year outcome of lesions in small coronary arteries by using a paclitaxel-iopromide-coated (3 µg/mm²) balloon catheter (DCB) has yielded good six-month angiographic and one-year clinical data. We now report the three-year clinical follow-up. METHODS AND RESULTS: One hundred and twenty patients with >70% stenoses <22 mm in length in small coronary vessels (vessel diameter: 2.25-2.8 mm) were treated with the DCB. The primary endpoint was angiographic in-segment late lumen loss. The secondary endpoints encompassed all other angiographic and clinical data up to three years post intervention. In total 82/120 (68.3%) patients with a vessel diameter of 2.35±0.19 mm were treated with the DCB only, and 32/120 (26.7%) patients required additional bare metal stent (BMS) deployment. Both the 12- and 36-month major adverse cardiac event rates were 5/82 (6.1%) for DCB only and 12/32 (37.5%) for DCB+BMS, primarily due to the need for target lesion revascularisation in 4/82 (4.9%) patients and 9/32 (28.1%) (p<0.001) patients, respectively. Total MACE rate after 36 months was 18/120 (15%; intention-to-treat). CONCLUSIONS: Treatment of small vessel coronary artery disease with a paclitaxel-iopromide-coated balloon exhibited good six-month angiographic and one-year clinical data that persisted during the three-year follow-up period. Randomised trials will clarify its role as an alternative to drug-eluting stents in the treatment of small vessel coronary artery disease. (ClinicalTrials.gov Identifier: NCT00404144).

ABSTRACT

BACKGROUND/OBJECTIVES: The purpose of this prospective, randomized, single-blind controlled clinical trial was to compare the effectiveness of a zotarolimus-eluting stent (ZoMaxx™) with a paclitaxel-eluting coronary stent (Taxus™ Express(2)™) in patients with angina pectoris and a single native coronary artery lesion between 10-28 mm in length and 2.5-3.75mm in diameter. METHODS: Patients were enrolled at 75 international institutions between June 2005 and November 2006. RESULTS: 1099 (1672 originally planned) patients received 557 ZoMaxx and 542 Taxus stents: cohorts were well-matched for diabetes (27% vs. 27%), reference vessel diameter (2.73 ± 0.46mm vs. 2.74 ± 0.45mm) and lesion length (14.8 ± 6.7mm vs. 14.3 ± 6.4mm). Nine month clinical and angiographic follow-up was available in 1052/1099 (96%) and 649/836 (78%) patients, respectively. The safety profiles for the two stents (myocardial infarction (MI), cardiac death and/or target vessel revascularization (TVR)) were similar (ZoMaxx 8.7% vs. Taxus 6.9%, p=NS). The primary endpoint of 9-month TVR occurred more frequently after treatment with ZoMaxx (6.8%) as compared with Taxus (4.2%), therefore the primary clinical endpoint was not met. However, the 9-month in-segment late lumen loss for ZoMaxx (0.29 ± 0.47mm) and Taxus (0.22 ± 0.41mm, p=NS) were similar, thus satisfying the primary angiographic endpoint. Secondary endpoints of the rates of in-segment and in-stent binary restenosis were also similar (5.9% vs. 5.8%, 7.8% vs. 7.9%, respectively). CONCLUSIONS: At 9months, the ZoMaxx stent failed to achieve the primary endpoint of non-inferiority in TVR to the Taxus stent, but safety endpoints were equal between the two stent systems.

ABSTRACT

BACKGROUND: Recent genome-wide association studies have identified several genetic loci linked to coronary artery disease (CAD) and myocardial infarction (MI). The 9p21.3 locus was verified by numerous replication studies to be the first common locus for CAD and MI. In the present study, we investigated whether six single nucleotide polymorphisms (SNP) rs1333049, rs1333040, rs10757274, rs2383206, rs10757278, and rs2383207 representing the 9p21.3 locus were associated with the incidence of an acute MI in patients with the main focus on the familial aggregation of the disease. METHODS: The overall cohort consisted of 976 unrelated male patients presenting with an acute coronary syndrome (ACS) with ST-elevated (STEMI) as well as non-ST-elevated myocardial infarction (NSTEMI). Genotyping data of the investigated SNPs were generated and statistically analyzed in comparison to previously published findings of matchable control cohorts. RESULTS: Statistical evaluation confirmed a highly significant association of all analyzed SNP's with the occurrence of MI (p<0.0001; OR: 1.621-2.039). When only MI patients with a positive family disposition were comprised in the analysis a much stronger association of the accordant risk alleles with incident disease was found with odds ratios up to 2.769. CONCLUSIONS: The findings in the present study confirmed a strong association of the 9p21.3 locus with MI particularly in patients with a positive family history thereby, emphasizing the pathogenic relevance of this locus as a common genetic cardiovascular risk factor.

ABSTRACT

BACKGROUND: Magnetic resonance imaging (MRI) of pacemaker patients is contraindicated due to documented potential risks to the patient from hazardous interactions between the MRI and pacemaker system. OBJECTIVE: The purpose of this prospective, randomized, controlled, worldwide clinical trial was to evaluate the safety and effectiveness of a pacemaker system designed for safe use in MRI for any bradycardia indicated patient. METHODS: Patients (n = 464) were randomized to undergo an MRI scan between 9 and 12 weeks postimplant (MRI group, n = 258) or not to undergo MRI (control group, n = 206) after successful implantation of the specially designed dual-chamber pacemaker and leads. Patients were monitored for arrhythmias, symptoms, and pacemaker system function during 14 nonclinically indicated relevant brain and lumbar MRI sequences. Sequences were performed at 1.5 T and included scans with high radiofrequency power deposition and/or high gradient dB/dt exposure. Clinical evaluation of the pacemaker system function occurred immediately before and after MRI, 1 week and 1 month post-MRI, and at corresponding times for the control group. Primary endpoints for safety analyzed the MRI procedure complication-free rate and for effectiveness compared capture and sensing performance between MRI and control groups. RESULTS: No MRI-related complications occurred during or after MRI, including sustained ventricular arrhythmias, pacemaker inhibition or output failures, electrical resets, or other pacemaker malfunctions. Pacing capture threshold and sensed electrogram amplitude changes were minimal and similar between study groups. CONCLUSION: This trial documented the ability of this pacemaker system to be exposed in a controlled fashion to MRI in a 1.5 T scanner without adverse impact on patient outcomes or pacemaker system function.

ABSTRACT

OBJECTIVES: The aim of this study was to compare eptifibatide and abciximab as adjuncts to primary percutaneous coronary intervention (PCI). BACKGROUND: The glycoprotein (GP) IIb/IIIa receptor inhibitor abciximab as adjunct to primary PCI in patients with ST-segment elevation myocardial infarctions has been shown to reduce ischemic complications and improve clinical outcomes. So far, no trial has been performed to compare the efficacy of another GP IIb/IIIa receptor inhibitor, eptifibatide, and abciximab in primary PCI. METHODS: A total of 427 patients with ST-segment elevation myocardial infarctions <12 h and planned primary PCI were randomized to double-bolus eptifibatide (n = 226) followed by a 24-h infusion or single-bolus abciximab (n = 201) followed by a 12-h infusion. In this noninferiority trial, the primary end point was the incidence of complete (> or =70%) ST-segment resolution (STR) 60 min after PCI, a measure of myocardial reperfusion. The assumption was a 60% complete STR rate in the abciximab group. The noninferiority margin was set to 15%. RESULTS: The incidence of complete STR at 60 min after PCI in the intention-to-treat analysis was 62.6% after eptifibatide and 56.3% after abciximab (adjusted difference: 7.1%; 95% confidence interval: 2.7% to 17.0%). All-cause mortality 6.2% versus 4.5% (p = 0.50); reinfarction 0.4% versus 3.5% (p = 0.03); target vessel revascularization 4.4% versus 6.5% (p = 0.40); the combined end point of death, nonfatal reinfarction, and target vessel revascularization 10.6% versus 10.9% (p = 0.90); stroke 0.5% versus 0.5% (p = 1.00) after 6 months; and Thrombolysis In Myocardial Infarction major bleeding complications 4.0% versus 2.0% (p = 0.20) after 30 days were observed after eptifibatide and abciximab, respectively. CONCLUSIONS: Eptifibatide as an adjunct to primary PCI is equally as effective as abciximab with respect to STR.

ABSTRACT

BACKGROUND: Treatment of lesions in small coronary arteries by percutaneous transluminal coronary intervention is limited by a high recurrence rate. We assessed the use of a paclitaxel-coated balloon in this indication. METHODS: One-hundred eighteen patients with stenoses in small coronary vessels were treated by a paclitaxel-coated balloon (3 microg/mm(2)). The main inclusion criteria encompassed diameter stenosis of > or =70% and < or =22 mm in length with a vessel diameter of 2.25-2.8 mm. Follow-up angiography was performed at scheduled 6-month post-intervention or whenever driven by clinical or electrocardiographic signs of ischemia. The primary endpoint was angiographic in-segment late lumen loss. RESULTS: Eighty-two of 118 patients (70%) with a vessel diameter of 2.35 +/- 0.19 mm were treated with the drug-coated balloon only, while 32 patients required additional stent deployment. The mean in-segment late lumen loss was 0.28 +/- 0.53 mm. In patients treated with the drug-coated balloon only, the in-segment late lumen loss was 0.16 +/- 0.38 mm. At 12 months, the rate of major adverse cardiac events was 15% which was primarily due to the need for target lesion revascularization in 14 patients (12%). In those with additional bare metal stent implantation geographical mismatch between coated-balloon dilatation and stent implantation was significantly associated with the occurrence of restenosis. CONCLUSION: Treatment of coronary stenosis in small coronary vessels with the paclitaxel-coated balloon was well tolerated. It may offer an alternative to the implantation of a drug-eluting stent (ClinicalTrials.gov Identifier: NCT00404144).

ABSTRACT

BACKGROUND: Treatment of in-stent restenosis with paclitaxel-coated balloon catheter as compared with plain balloon angioplasty has shown surprisingly low late lumen loss at 6 months and fewer major adverse cardiac events up to 2 years. We compared the efficacy and safety of a paclitaxel-coated balloon with a paclitaxel-eluting stent as the current standard of care. METHODS AND RESULTS: One hundred thirty-one patients with coronary in-stent restenosis were randomly assigned to treatment by a paclitaxel-coated balloon (3 microg/mm2) or a paclitaxel-eluting stent. The main inclusion criteria encompassed diameter stenosis of > or =70% and < or =22 mm in length, with a vessel diameter of 2.5 to 3.5 mm. The primary end point was angiographic in-segment late lumen loss. Quantitative coronary angiography revealed no differences in baseline parameters. At 6 months follow-up, in-segment late lumen loss was 0.38+/-0.61 mm in the drug-eluting stent group versus 0.17+/-0.42 mm (P=0.03) in the drug-coated balloon group, resulting in a binary restenosis rate of 12 of 59 (20%) versus 4 of 57 (7%; P=0.06). At 12 months, the rate of major adverse cardiac events were 22% and 9%, respectively (P=0.08). This difference was primarily due to the need for target lesion revascularization in 4 patients (6%) in the coated-balloon group, compared with 10 patients (15%) in the stent group (P=0.15). CONCLUSIONS: Treatment of coronary in-stent restenosis with the paclitaxel-coated balloon was at least as efficacious and as well tolerated as the paclitaxel-eluting stent. For the treatment of in-stent restenosis, inhibition of re-restenosis does not require a second stent implantation.

ABSTRACT

BACKGROUND: Cinaciguat (BAY 58-2667) is the first of a new class of soluble guanylate cyclase activators in clinical development for acute decompensated heart failure. We aimed to assess the hemodynamic effects, safety, and tolerability of intravenous cinaciguat in patients with acute decompensated heart failure (pulmonary capillary wedge pressure > or =18 mm Hg). METHODS AND RESULTS: After initial dose finding (part A; n=27), cinaciguat was evaluated in the nonrandomized, uncontrolled proof-of-concept part of the study (part B; n=33) using a starting dose of 100 microg/h, which could be titrated depending on hemodynamic response. Patients were categorized as responders if their pulmonary capillary wedge pressure decreased by > or =4 mm Hg compared with baseline. Final doses of cinaciguat after 6 hours of infusion in part B were 50 microg/h (n=2), 200 microg/h (n=12), and 400 microg/h (n=16). Compared with baseline, a 6-hour infusion of cinaciguat led to significant reductions in pulmonary capillary wedge pressure (-7.9 mm Hg), mean right atrial pressure (-2.9 mm Hg), mean pulmonary artery pressure (-6.5 mm Hg), pulmonary vascular resistance (-43.4 dynes . s . cm(-5)), and systemic vascular resistance (-597 dynes . s . cm(-5)), while increasing heart rate by 4.4 bpm and cardiac output by 1.68 L/min. The responder rate was 53% after 2 hours, 83% after 4 hours, and 90% after 6 hours. Cinaciguat was well tolerated, with 13 of 60 patients reporting 14 drug-related treatment-emergent adverse events of mild to moderate intensity, most commonly hypotension. CONCLUSIONS: Cinaciguat has potent preload- and afterload-reducing effects, increasing cardiac output. Further investigation of cinaciguat for acute decompensated heart failure is warranted.

ABSTRACT

BACKGROUND: Conventional coronary artery bypass grafting (CABG) is recognized as the treatment of choice for left main coronary artery stenosis (LMCA) with excellent results. Patch angioplasty is an alternative method in selected cases for ostial stenosis of the LMCA. However, the long-term outcome data of this surgical technique are lacking. Therefore, the aim of this study was to evaluate the long-term outcome of patients treated by patch angioplasty using saphenous vein for ostial stenosis of the LMCA. METHODS: Nineteen patients underwent vein patch angioplasty for ostial LMCA stenosis between 1995 and 2005 at our institution. On three of them simultaneous aortic valve replacement was carried out and on one patient concomitant coronary artery bypass grafting of the right coronary artery was performed. Patients were followed up clinically and by magnetic resonance imaging (MRI) at 5.11 +/- 3.34 years (range 0.6-10 years). RESULTS: The early postoperative course was uneventful in all patients. There were no in-hospital deaths. In the late course, three patients died from unrelated causes three and a half, four, and six years after surgery. Importantly, at the time of follow-up the MRI revealed no restenosis or aneurysmatic coronary formation. All patients were in excellent clinical condition at follow-up. CONCLUSIONS: Surgical patch angioplasty with saphenous vein for isolated ostial LMCA stenosis is a safe operative technique with good long-term results. MRI is able to adequately depict the operative result of left main coronary ostium reconstruction.

ABSTRACT

BACKGROUND: Patients with persistent atrial fibrillation (AF) scheduled for electrical cardioversion need immediate anticoagulation. Unfractionated heparin (UFH) is often used for early anticoagulation in these patients before oral anticoagulation becomes effective. However, dose adjustment is required to achieve a two- to three-fold prolongation of the activated partial thromboplastin. Low molecular weight heparins, given in body weight-adjusted or independent fixed dosage, require less laboratory monitoring and are also effective within hours of first dosing. They seem to be an attractive alternative to UFH. Previous evidence has shown that these drugs are safe and effective in this indication. PATIENTS AND METHODS: In this prospective, open-label, multicenter pilot study, 203 patients were enrolled with persistent non-valvular AF scheduled for electrical cardioversion. Patients received a fixed dose of 8000 U anti-Xa certoparin twice daily starting immediately after enrolment and before cardioversion was performed. Patients with AF > 48 h underwent transoesophageal echocardiography (TEE) before cardioversion to exclude intra-atrial thrombi. After cardioversion, overlapping oral anticoagulation was started. Treatment with certoparin was stopped only after two consecutive days with INR values >2. OBJECTIVES: The objective was to document the feasibility and safety of a short-term treatment with a fixed, body weight-independent certoparin regimen (2 x 8000 U anti-Xa). RESULTS: Out of 203 patients enrolled, 200 received at least one dose of certoparin and were included in the analysis (safety population). Median treatment duration with certoparin was 7 days. Bleedings were observed in 8 patients (4.0%) and were classified as major (1.5%) or minor (2.5%). Cerebral ischemia was reported for 1 patient (0.5%). One patient showed mild thrombocytopenia (0.5%). There were no reports of venous thromboembolism or death during the treatment period. CONCLUSION: Certoparin administered at 8000 U anti-Xa twice daily independent of body weight was safe and appeared to be effective in patients with non-valvular AF undergoing electrical cardioversion. Its ease of use and the possibility of treatment on an outpatient basis make it an attractive option for early anticoagulation in AF.

ABSTRACT

BACKGROUND: Coronary artery fistula is a rare congenital malformation. Complications such as intracardiac shunts, endocarditis, myocardial infarction, aneurysm and sudden death can be observed. The purpose of this article is to present our experience with concomitant cardiac pathologies and discuss various therapeutic approaches including surgical and percutaneous intervention. MATERIALS AND METHODS: During 18,272 diagnostic cardiac catheterizations, coronary artery fistulas were identified incidentally in 10 patients (0.05%). There were 3 female and 7 male patients. The patients' ages ranged from 42 to 76 years. All patients with coronary artery fistula were preoperatively in New York Heart Association functional class and Canadian Cardiovascular Society class II or III. RESULTS: In addition to coronary artery fistula, coronary artery disease was detected in 4 patients (40%), a ventricular septal defect and an aneurysm of the sinuses of Valsalvae with aortic regurgitation in one patient (10%) and an anomalous origin of the LAD from the pulmonary trunk in one patient (10%) during cardiac catheterization. Four (40%) of the total of 10 patients had only coronary artery fistula. Surgical closure of the coronary artery fistula was performed in 7 patients (70%). An interventional fistula closure with a coil device was confirmed by cardiac catheterization in another 3 patients (30%). One patient of the latter group showed a small residual shunt from the LAD to the pulmonary trunk. No death or long-term morbidities could be observed.
