BACKGROUND Patients who present with myocardial infarction (MI) and unprotected left main coronary artery (ULMCA) disease represent an extremely high-risk subset of patients. ULMCA percutaneous coronary intervention (PCI) with drug-eluting stents (DES) in MI patients has not been extensively studied. METHODS In this retrospective multicenter international registry, we evaluated the clinical o...

OBJECTIVES The investigators undertook a systematic, comprehensive analysis of the therapeutic response and clinical outcomes of reperfusion therapy for acute ST-segment elevation myocardial infarction (STEMI) in 5,470 patients from the Assessment of the Safety and Efficacy of a New Thrombolytic Regimen (ASSENT)-3 trial. BACKGROUND Prompt effective reperfusion therapy for acute STEMI may atte...

Measurement invariance (MI) is a pre-requisite for comparing latent variable scores across groups. The current paper introduces the concept of approximate MI building on the work of Muthén and Asparouhov and their application of Bayesian Structural Equation Modeling (BSEM) in the software Mplus. They showed that with BSEM exact zeros constraints can be replaced with approximate zeros to allow f...

PURPOSE It remains controversial whether mini-incision (MI) benefits patients in total hip arthroplasty (THA). We performed a meta-analysis of randomized controlled trials (RCTs) to assess the effects of MI on surgical and functional outcomes in THA patients. METHODS A systematic electronic literature search (up to May 2013) was conducted to identify RCTs comparing MI with standard incision (...

The indication for prophylactic temporary and permanent pacing during acute myocardial infarction (MI) complicated by bundle branch block is high risk of progression via a Type II pattern to second or third degree (high degree) AV block during hospitalization or follow-up. In this study, determinants of high degree AV block during hospitalization and sudden death or recurrent high degree block ...

the chronobiology of the acute myocardial infarction (ami) is an interesting matter for recognition of the biological mechanism that might trigger ami. the present study was aimed to investigate the circadian, seasonal and circannual variation of the ami occurrence with solar, lunar, and christian months. a retrospective study of 1174 cases with diagnosis of ami was conducted. all cases include...

Background Several observational and preclinical studies have shown that blood transfusion may modify the mortality of patients with myocardial infarction (MI). The aim of this meta-analysis is to evaluate the recent evidence on the effectiveness of blood transfusion for all-cause mortality in patients with MI. Materials and Methods PUBMED, EMBASE and the Cochrane central register of controll...

Using an adaptation of Qin Jiushao’s method from the 13th century, it is possible to prove that a system of linear modular equations ai1xi + · · · + ainxn = ~bi mod ~ mi, i = 1, . . . , n has integer solutions if mi > 1 are pairwise relatively prime and in each row, at least one matrix element aij is relatively prime to mi. The Chinese remainder theorem is the special case, where A has only one...

The space available to our perception is three-dimensional with full evidence. development of physics led the hypothesis extra dimensions. It believed that an important role in unification should play by Planck units mass, length and time, built on universal constants c (the speed light a vacuum), id="M2"> G gra...

Purpose: In order to take full advantage of the many imaging modalities available today such as CT, MRI, PET etc., accurate image registration is essential. Mutual information (MI) registration is a commonly used and robust method as it is based on the complete image information instead of fiducial markers or anatomical landmarks. However, MI registration is often dominated by the patient exter...
