title: Knowledge of heart disease and stroke among cardiology inpatients and outpatients in a Canadian inner-city urban hospital.
abstract: BACKGROUND
  Heart disease and stroke are leading causes of death in North America. Nevertheless, in 2003, the Heart and Stroke Foundation of Canada reported that nearly two-thirds of Canadians have misconceptions regarding heart disease and stroke, echoing the results of similar American studies. Good knowledge of these conditions is imperative for cardiac patients who are at greater risk than the general population and should, therefore, be better educated. The present study evaluated the awareness of heart disease and stroke among cardiac patients to assess the efficacy of current education efforts.
  
  
  METHODS
  Two hundred fifty-one cardiac inpatients and outpatients at St Michael's Hospital (Toronto, Ontario) were surveyed in July and August 2004. An unaided questionnaire assessed respondents' knowledge of cardiovascular risk factors, symptoms of heart attack and stroke, and actions in the event of cardiovascular emergency. Demographic data and relevant medical history were also obtained.
  
  
  RESULTS
  Cardiac patients demonstrated relatively adequate knowledge of heart attack warning symptoms. These patients also demonstrated adequate awareness of proper actions during cardiovascular emergencies. However, respondents were not aware of the most important risk factors for cardiovascular disease. Knowledge of stroke symptoms was also extremely poor. Socioeconomic status, and personal history of heart attack and stroke were positively correlated with good knowledge.
  
  
  CONCLUSIONS
  Future patient education efforts should address the awareness of the important cardiovascular risk factors and knowledge of cardiovascular warning symptoms (especially for stroke), as well as inform patients of appropriate actions during a cardiovascular emergency. Emphasis should be placed on primary and secondary prevention, and interventions should be directed toward low-income cardiac patients.
