简要总结
The purpose of this study is to determine the prognostic impact of the presence of chronic total occlusions (CTO) of the coronary arteries in patients undergoing coronary angiography and PCI.
详细描述
The SCAAR registry
The SCAAR registry was established in 1999 and is a part of the national SWEDEHEART registry. The registry gathers data on all consecutive patients from all hospitals that perform coronary angiography and PCI in Sweden. The information about clinical characteristics and procedural details is entered into the registry immediately after the procedure by the PCI physician after the review of clinical information. SCAAR is independent of commercial funding and is sponsored by the Swedish Health Authorities only. The technology has been developed and administered by the Uppsala Clinical Research Center, Uppsala, Sweden. Since 2001, it has a web-based case-report platform with automatic data surveillance.
Study population
The study population consisted of all consecutive patients that underwent coronary angiography or PCI in Sweden who were registered between 2005 to 2012 in Swedish Coronary Angiography and Angioplasty Registry (SCAAR).
