    Parenteral antithrombotic therapy during primary percutaneous coronary intervention

    Acute myocardial infarction (AMI) is a major cause of morbidity, mortality and disability worldwide. ST-segment elevation myocardial infarction (STEMI) accounts for 25-40% of AMI presentations. Arterial thrombosis due to atherosclerotic plaque rupture with formation of an occlusive thrombus is the main cause of STEMI. Platelets and coagulation factors are the two principal elements involved in this process. The main goal of STEMI treatment is the early reperfusion. Prompt primary percutaneous coronary intervention (pPCI) together with an appropriate antithrombotic therapy are the treatment of choice in this setting. In this chapter, we provide an overview of currently available parenteral antithrombotic therapies used in patients with STEMI undergoing pPCI

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
