The collection of data to describe the nationwide practice of percutaneous coronary intervention (PCI) in the UK started with the inception of the British Cardiovascular Intervention Society (BCIS) in 1988. From 1988 to 1991 annual surveys of PCI activity were published in the British Heart Journal. Annual reports from 1992 onwards are available for download from the society's website (http://www.bcis.org.uk), and summaries of some of the key data have been published as reports for distribution to participating hospitals and networks. The initial data collection process was essentially a descriptive survey of activity. Over time the process has evolved becoming more sophisticated with electronic methods for data collection developed by the Central Cardiac Audit Database (CCAD) group. The methods were tested in 1996 as a pilot in selected hospitals, and full UK-wide participation in the electronic collection of PCI data was achieved by 2005.~The proposed study includes one of the largest coronary interventional and surgical programmes in the UK at Europe's largest cardiac centre (BHC). This has allowed us to accumulate a large number of patients in just over 4 years. All patients undergoing PCI and CABG are included in this study using a clinical database. The database is password-protected and includes demographic, clinical and outcome data.~The database includes patients with simple to complex CAD. We will use this database to test several hypothesis including but not limited to investigating characteristics of patients treated, complications of interventional treatment and outcomes of patients. This research will add substantially to the literature by providing real-world data from a leading coronary centre.
Despite the year-on-year decrease, coronary artery disease (CAD) still remains one of the leading cause of mortality worldwide. With advances in technology and our understanding of cardiac disease, we can now treat CAD using minimally invasive interventional techniques. This has revolutionised treatment for and improved the lives of many patients with CAD. Although trials have assessed various therapeutic strategies in various populations, real-world evidence of intervention and medical treatment among patients with CAD is increasingly recognised as an important part of providing safety and efficacy data and improving the care we provide.~This data will add to that literature by assessing the characteristics and outcomes of patients with CAD. It will also identify and characterise predictors of outcomes, improve risk stratification and diagnostic evaluation.
