Article-Article Co-Citation Network of the Cardiac Literature in 2009. The network map was prepared as described for Figure 5. Sheet 3B in the Additional File lists the articles published here. The most recent articles are divided into distinct clusters by clinical topic. On the far left are articles about drug-eluting stents (from Morice 2002 to Stone 2007), adjacent to another thin cluster about clopidogrel and anti-platelet agents (Yusuf 2001, Mehta 2001, Wivott 2007). The central cluster has concentrations of articles about cholesterol, atherosclerosis, and myocardial infarction (Wilson 1998, Libby 2004, Yusuf 2004, Hansson 2005), then hypertension (Dahlof 2002, Chobanian 2003, Mancia 2007), and atrial fibrillation (Haissaguerre 1998, Go 2001, Pappine 2004, Fuster 2006). The right edge of the cluster has articles about echocardiography (Nagueh 1997, Ommen 2000, Lang 2005). Finally, at the extreme right of the map sit articles about implanted defibrillators and biventricular pacing (Moss 1997, Bristow 2004, Bardy 2005, Chung 2008). As was seen in the cancer map, the most enduring articles all involve specific clinical or laboratory techniques, such as measurement of LDL (Friedeweld 1972) or creatinine clearance (Cockcroft 1976), or standards, whether for grading coronary artery disease (Austen 1975) or quantifying echocardiography (Devereux 1977, Schiller 1989).
