Cardiovascular Health Indicator
Measure: Heart Disease Death Rate

Analysis

As shown in Chart 1 and Table 1 below, the heart disease death rate has declined since 2006, but it still remains the second-leading cause of death in Minnesota. More men die of heart disease than women, and at younger ages, which explains the higher age-adjusted death rate for men compared to women. Total deaths were lowest in 2010 and have risen by 20% in the years since, with 1,400 more deaths in 2020 compared to ten years earlier. Most of that increase has been in men. Even though the number of deaths has started to increase, death rates have remained relatively stable. This can be explained by our aging population, with the number of older people who are at a risk of dying from heart disease also increasing each year.

Even though Minnesota has a very low rate of heart disease deaths compared to the United States, there are large disparities in the state. As shown in Chart 2 and Table 2, the death rate due to heart disease is highest in American Indian communities in Minnesota and lowest in Asian/Pacific Islander and Latinx/Hispanic communities. The last column of Table 2 shows a rate ratio, which compares two rates to describe how much one group is impacted compared to another. Any number larger than 1 means that the group of interest is higher than the comparison group. Any number smaller than 1 means that the group of interest is lower than the comparison group. In Table 2, communities of color are compared to the overall Minnesota population. American Indian people die from heart disease at a rate 1.58 times higher than Minnesotans overall. While the age-adjusted death rate shows little difference in heart disease deaths between African-American/African Born Minnesotans and the overall Minnesota population, a different picture emerges when looking at death by age groups starting at 35 years. These disparities in deaths are rooted in historical inequities that have persisted in the United States and Minnesota for many years.

Chart 3 and Table 3 highlight major disparities in heart disease deaths for African American/African Born and American Indian people in Minnesota. Chart 3 below shows the difference in death rates between African American/African Born and American Indian people compared to the overall Minnesota population from 2016-2020 by using a rate ratio. Bars that rise above the solid black line show groups that die at higher rates than Minnesotans overall, while bars that remain below the solid black line show groups that die at lower rates.

Among those aged 35 through 64, African American/African Born people die from heart disease at about 2 times the death rate for Minnesotans overall. For American Indian people, this disparity is even greater, with death rates approximately 3.5 times higher among those aged 35 to 54, and more than 2.5 times higher among those aged 55 to 74. Both African American/African Born and American Indian people over the age of 85 die from heart disease at a lower rate than Minnesotans overall, but this may be because those who have heart disease in these groups are dying at much younger ages. Table 3 shows the age-specific death rates for African American/African Born and American Indian people, and the rate ratio comparing them to the overall Minnesota population. Asian/Pacific Islander and Latinx/Hispanic communities have lower death rates than the overall Minnesota population in every age group and are not shown in Chart 3 or Table 3.

The number of deaths due to heart disease increases in older age groups. Table 4 shows the number of deaths and death rate due to heart disease over the three most recent five-year time periods. Over that 10 year period, the largest declines in death rates have been for Minnesotans ages 65 to 84, as shown in Chart 4. For Minnesotans ages 45 to 64, and 85 or older, the declines have been very small. For Minnesotans under age 45, there has a small increase in the heart disease death rate.

Measure Definition

Since 1999, Heart disease deaths are identified as the underlying cause of death on death certificates as ICD-10: I00-I09, I11, I13, and I20-I51. This includes the following broad categories: Acute rheumatic fever, chronic rheumatic heart disease, hypertensive heart disease, hypertensive heart and renal disease, ischemic heart diseases, pulmonary heart disease and diseases of pulmonary circulation, and other forms of heart disease.
