title: Study design and baseline characteristics of the national observational study of diagnostic and interventional cardiac catheterization by the French Society of Cardiology.
abstract: The national observational study of diagnostic and interventional cardiac catheterization (ONACI) is a prospective multicenter registry of the French Society of Cardiology including all interventional cardiology procedures performed from 2004. We aimed to evaluate "real-world" management of patients with coronary artery disease in France from this registry. The present study was focused on data collected from 2004 to 2008. Patient demographics and co-morbidities, invasive parameters, treatment options, and procedural techniques were prospectively collected. Patients were recruited from 99 hospitals (55% of patients were hospitalized in private clinics and 45% in public institutions). During a 5-year period, a total of 298,105 patients underwent coronary angiography and 176,166 patients underwent percutaneous coronary intervention. Diagnosis was acute coronary syndrome in 22%, stable angina or silent ischemia in 23%, and atypical chest pain in 9% of cases. Normal coronary arteries or nonsignificant coronary narrowing were found in 26% of patients. Radial access was increasingly used over the years regardless of the indication. The average number of percutaneous coronary interventions per procedure was 1.5 ± 0.7 (range, 1.3 ± 0.7 to 1.5 ± 0.7) and that of stents per procedure was 1.5 ± 0.8 (range, 1.5 ± 0.8 to 1.6 ± 0.8). Drug-eluting stents were used in 45% (range, 34% to 62%), increasing from 2004 to 2006, and then decreasing after the 2006 controversy. In conclusion, ONACI is one of the largest catheterization registries during this period, providing a detailed and comprehensive global description of the spectrum and management of patients with suspected coronary artery disease undergoing cardiac catheterization.
