- AIM:Postcardiotomy cardiogenic shock (PCCS) is associated with high mortality rates, despite full conventional treatment. Although the results of treatment with surgically implantable ventricular assist devices have been encouraging, the invasiveness of this treatment limits its applicability. Several less invasive devices have been developed, including the Impella system. The objective of this study was to describe our three-center experience with the Impella 5.0 device in the setting of PCCS.METHODS:From January 2004 through December 2010, a total of 46 patients were diagnosed with treatment-refractory PCCS and treated with the Impella 5.0 percutaneous left ventricular assist device at three european heart centers. Baseline and follow-up characteristics were collected retrospectively and entered into a dedicated database.RESULTS:Within the study cohort of 46 patients, mean logistic and additive EuroSCORES were 24 ± 19 and 10 ± 4. The majority of patients underwent coronary artery bypass grafting (48%) or combined surgery (33%). Half of all patients had been treated with an intra-aortic balloon pump before 5.0-implantation, 1 patient had been treated with an Impella 2.5 device. All patients were on mechanical ventilation and intravenous inotropes. The Kaplan-Meier estimate of overall 30-day survival was 39.5%.CONCLUSION:Thirty-day survival rates for patients with PCCS, refractory to aggressive conventional treatment and treated with the Impella 5.0 device, are comparable to those reported in studies evaluating surgically implantable VADs, whereas the Impella system is much less invasive. Therefore, mechanical circulatory support with the Impella 5.0 device is a suitable treatment modality for patients with severe PCCS.

- The optimal choice of oral P2Y12 receptor inhibitors has the potential to significantly influence outcomes. We seek to compare the safety and efficacy of the three most commonly used oral P2Y12 receptor inhibitors (clopidogrel, prasugrel, and ticagrelor) in acute coronary syndromes (ACS) via a comprehensive systematic review and network meta-analysis.We will perform a comprehensive search for randomized clinical trials which compared cardiovascular and hemorrhagic outcomes after use of at least two of the distinct oral P2Y12 receptor inhibitors (i.e. clopidogrel, prasugrel, and ticagrelor). In addition, key inclusion criteria will be trial size of at least 100 patients and at least 1 month of follow-up time. Several pre-specified subgroups will be explored, including Asian patients, patients presenting with ST-elevation myocardial infarction, patients of advanced age, and others.Exploratory frequentist pairwise meta-analyses will be based primarily on a random-effects method, relying on relative risks (RR) for short-term endpoints and incidence rate ratios (IRR) for long-term endpoints. Inferential frequentist network meta-analysis will be based primarily on a random-effects method, relying on RR and IRR as specified above. Results will be reported as point summary of effect, 95% CI, and p-values for effect, and graphically represented using forest plots.An international collaborative network meta-analysis has begun to comprehensively analyze the safety and efficacy of prasugrel, ticagrelor and clopidogrel, each on a background of aspirin, for management of patients with ACS. It is our hope that the rigor and breadth of the undertaking described herein will provide novel insights that will inform optimal patient care for patients with ACS treated conservatively, or undergoing revascularization.

- AIM: This study was undertaken to increase understanding of the utilization of a newly introduced statin through evaluation of characteristics of 'real-life' patients in a pharmacoepidemiology program in the USA, the Netherlands, the UK and Canada. METHODS: This was an observational analysis of prospectively collected data from primary care patients classified as new users of rosuvastatin or any other statin. New users (naïve or switched initiators) of rosuvastatin were compared with initiators of other statins, as identified from automated healthcare databases in the first 1 to 2 years of rosuvastatin availability. Demographics, statin doses, previous statin use and other lipid-lowering therapies, and relevant comorbidities were recorded. The main outcome measure was proportion of naïve and non-naïve statin users in patients prescribed rosuvastatin or 'other statins'. RESULTS: Among 346.547 new statin users identified in the cohorts, 46.838 (13.5%) were new users of rosuvastatin and most (84.1%) were statin-naïve. Patients receiving rosuvastatin were more likely to have been previously treated with another statin or non-statin lipid-lowering therapy and tended to be younger, compared with first users of other statins. CONCLUSION: These findings suggest that rosuvastatin is preferentially prescribed to patients who have not responded satisfactorily to established treatment.
