CCORT• CCORT is a group of over 30 outcomes researchers from
5 provinces (NS, QC, ON, AB, BC) who are working together on projects to measure and improve the quality of cardiac care in Canada
• Funded by a CIHR Team Grant in Cardiovascular Outcomes Research
• Institute for Clinical Evaluative Sciences (ICES) in Toronto is the national coordinating centre for CCORT
• www.ccort.ca
CIHR Team Grant in Cardiovascular Outcomes Research
Purpose of Study• To examine national trends between 1994 and
2004, in hospitalizations and death rates for acute myocardial infarction, heart failure and stroke
• To see whether the rate of change for these three conditions has been similar or different
CIHR Team Grant in Cardiovascular Outcomes Research
Methods• We analyzed mortality data from Statistic Canada’s
Canadian Mortality Database and data on hospital admissions from the Canadian Institute for Health Information’s Hospital Morbidity Database for the period 1994-2004
• We determined age- and sex-standardized rates of death and hospital admissions per 100,000 population aged 20 years and over as well as in-hospital case-fatality rates
CIHR Team Grant in Cardiovascular Outcomes Research
Overview• The following is a set of slides that highlight key findings
from the original manuscript including the following:– Decrease in mortality rates– Decrease in hospital admission rates– Decrease in in-hospital case-fatality rates– Differences between men and women in relation to mortality
and hospitalization rates• Please feel free to use these slides to disseminate this
information

Conclusions• Mortality, hospitalization and in-hospital case-fatality rates
for heart disease decreased significantly between 1994-2004• For the first time in Canada, more women than men died from
cardiovascular disease in 2000• Efforts to prevent cardiovascular disease have been
successful but may have delayed the onset of disease until people are older
• Further prevention, treatment and national surveillance of cardiovascular disease is continuously required as it is still the leading cause of death in Canada
Reasons for mortality decline• Better heart disease prevention
– Decreasing smoking rates– Greater awareness and control of hypertension– Decreasing cholesterol levels (i.e. statins)
