Conflicts of interest (COIs) may influence medical literature. However, it is unclear whether medical journals have consistent policies for defining and soliciting COI disclosures. ⋯ In 2008, most medical journals with relatively high impact factors had author COI policies available for public review. Among journals, there was substantial variation in policies for solicitation of author COIs and in definitions of COI.

Earlier studies indicate an inverse relationship between hospital volume and mortality after primary angioplasty for patients presenting with ST-segment elevation myocardial infarction (STEMI). However, contemporary data are lacking. ⋯ In a contemporary registry of patients with STEMI, higher-volume primary angioplasty centers vs lower-volume centers were associated with shorter DTB times and more use of evidence-based therapies, but not with adjusted in-hospital mortality or length of hospital stay.
