title: [Geographical differences in clinical characteristics and management of stable outpatients with coronary artery disease: comparison between the Italian and international population included in the Worldwide CLARIFY registry].
abstract: BACKGROUND
  Limited data are available regarding specific differences among countries in demographic and clinical characteristics and treatment of patients with stable coronary artery disease.
  
  
  METHODS
  CLARIFY is an international, prospective and longitudinal registry including more than 33 000 patients with stable coronary artery disease enrolled in 45 countries worldwide. Data were used to compare the characteristics of patients enrolled in Italy with those enrolled in Europe and in the rest of the world.
  
  
  RESULTS
  Baseline data were available for 33 283 patients, 2112 of whom from Italy and 12 614 from the remaining western European countries. Italian patients were found to be older, more frequently smoker, hypertensive and with sedentary habits. In addition, they presented more frequently a history of myocardial infarction, carotid arterial disease and chronic obstructive pulmonary disease. In addition, when compared with patients of both European and international cohorts, more Italian patients had undergone coronary angiography and angioplasty. As far as treatment was concerned, a greater number of Italian patients were taking ivabradine, angiotensin-converting enzyme inhibitors and/or angiotensin receptor blockers, nitrates, thienopyridines, while those taking beta-blockers, calcium antagonists and other antianginal medications were fewer.
  
  
  CONCLUSIONS
  Among ambulatory patients with stable coronary artery disease, there are important geographic differences in terms of risk factors, clinical characteristics, surgical and pharmacological treatment.
