Demographic and clinical characteristics of patients with stable coronary artery disease: results from the CLARIFY registry in Spain

INTRODUCTION AND OBJECTIVES: Coronary artery disease is associated with high morbidity and mortality. The objective of the CLARIFY registry is to study the treatment of outpatients with coronary artery disease in the setting of daily clinical practice.METHODS: The CLARIFY registry is a prospective registry conducted in 41 countries that included outpatients with stable coronary artery disease attending primary care or specialist units between October 2009 and June 2010. The present study describes the baseline characteristics of the Spanish cohort compared with the western European cohorts included in the registry.RESULTS: A total of 33,248 patients were included: 14,726 in western Europe and 2257 in Spain (selected by 192 cardiologists). The majority of the participants in Spain were men (81%) with a mean age of 65 years. There was a higher frequency of diabetes (34% vs 25%; P<.0001), coronary artery disease family history (19% vs 31%; P<.0001), myocardial infarction (64% vs 60%; P<.0001), and stroke (5% vs 3%; P=.0007) in the Spanish cohort than in the western European cohorts. The most common treatments in the Spanish sample were lipid-lowering drugs (96%), acetylsalicylic acid (89%), and beta-blockers (74%).CONCLUSIONS: Patients in the Spanish cohort are similar to those in the western European cohorts and seem to be representative of the Spanish population with coronary artery disease. Therefore, they form a suitable basis for the study of prognostic factors at 5-year follow-up.
