Data components
The Project developed data collection methodology for:
- standardized coronary and stroke event registration, including collection
of data on diagnostic information.
- data on medical care of patients before, during and after the attack. The
methods were developed taking into account the local characteristics of the
health care system in each Centre.
- risk factor measurements through sample surveys of the study population.
This includes
- identification of suitable sampling frames.
- sample selection.
- methods for obtaining optimal response rates.
- standardized valid measurement of the main cardiovascular risk factors,
with focus on
- smoking habits
- blood pressure and its treatment
- serum or plasma total and HDL cholesterol
- height, weight, marital status and education
- Also, methods were developed to collect data on a number of aspects of
more recent interest, like awareness and treatment of high cholesterol,
use of aspirin and contraceptive pills, and on menopause.
- routinely available data on population size and mortality in the study
populations.
- medical services data through
- a special inventory of services, diagnostic and therapeutic procedures
for the management of coronary heart disease available to the populations of
Centres, 1980-1994.
- routinely available data on hospital admissions for management of
coronary heart disease (including coronary artery procedures).
