HEART DISEASES
Cardiovascular Disease
Cardiovascular disease (CVD) refers to a wide variety
of heart and blood vessel diseases and conditions, including coronary
heart disease, stroke, high blood pressure, high blood cholesterol, and
rheumatic heart disease. Heart disease is the first and stroke is the
third leading cause of death in the State.
For the general population, the mortality rates in Minnesota
are generally lower than in the nation as a whole; however, for the American
Indian population in Minnesota the death rates from 1990 through 1998
were 33% higher than the State population and 44% higher than the total
U.S. American Indian population. Age adjusted death rates also indicate
considerable disparities in heart disease for African American females
living in Minnesota. Asians living in Minnesota are more likely than other
population groups to suffer from stroke.
Contributing Factors
Atherosclerosis, the underlying disease process of the
major forms of CVD, is a slowly progressive condition that begins in childhood.
It is associated with several modifiable risk factors including: high
blood pressure, cigarette smoking, physical inactivity, diabetes, obesity,
and poor diet. Control of modifiable risk factors at the population and
individual level is key to prevention of CVD and its complications. Coronary
heart disease is rarely found in populations without elevated cholesterol.
Stroke is most strongly associated with high blood pressure.
CVD incidence and mortality rates are higher among people
of lower socioeconomic status.
The greatest declines in CVD mortality over time have
been among those at the highest income and educational levels. These differences
have been attributed to the greater prevalence of risk factors (obesity,
lack of exercise, high blood pressure, smoking) within lower SES populations
and, also, to the effects of neighborhood socioeconomic status. For instance,
nationwide, the percentage of students watching more than 2 hours of television
per school day is: Whites - 34%, Hispanics - 52%, African Americans -
74%.
Current MDH Activities
The Department recently received a three-year grant from
the Centers for Disease Control to develop a comprehensive state plan
to promote cardiovascular health. The Department will seek close collaboration,
with those population groups most at risk of premature death and disability
due to CVD, to identify an overall strategy and effective, readily disseminated
local interventions that will reduce risk factors for CVD.
The Department has participated in the development of
several widely recognized, skills-based school health curriculums for
promoting a healthier diet and increased physical activity among children.
The Department of Health also staffs the Minnesota Council on Physical
Activity and Sports and the Minnesota 5-a-Day Coalition. These coalitions
each have broad participation from the public and private sector (70+
member organizations each) to support physical activity and fruit and
vegetable consumption statewide.
Community Strategies
The type of projects that would be implemented with this
funding will build on successful models that have been developed in several
southern states such as the Bootheel project in Missouri. The Bootheel
project, a community-based cardiovascular risk-reduction program, demonstrated
in a six county area that with even modest resources, community-based
interventions could reduce self-reported risk for cardiovascular disease
within a relatively brief period. The Bootheel project included such activities
as exercise groups, healthy cooking demonstrations, blood pressure and
cholesterol screenings, and cardiovascular disease education.
Examples of community interventions include:
- expanding the amount and availability of green space (i.e., parks
and trails)
making neighborhoods more walkable and bicycle-friendly (improved
safety, new or better lit sidewalks)
- supporting a farmers' market
- conducting low-fat milk campaigns or 5-A-Day campaigns for fruits
and vegetables
- media campaigns tailored to racial and ethnic and American Indian
populations
- blood pressure screening and control campaigns
- cholesterol screening and control campaigns
Anticipated Outcomes
Programs such as these will lead to increased physical
activity, better diet, and less obesity. Short-term benefits include increased
productivity and a reduction in the need for medical interventions, such
as treatment for high blood pressure or high cholesterol.
African-American and Hispanic populations in Minnesota
are much less likely to have had their blood pressure checked in the last
six months compared to Whites. Communities implementing hypertension screening
programs could eliminate this disparity in screening rates in their communities.
Over time, these changes will lead to a reduction in
cardiovascular disease and related diseases and reduced incidence of premature
death and disability.
