Investigation unveils increase in deaths from diabetes and cardiovascular disease

After an initial decline in diabetes mellitus and cardiovascular disease-related deaths, researchers from Emory and other institutions have noted a reversal of the trend, with mortality rates increasing from 2014 to 2019, according to a new study published May 12 in the The American Journal of Medicine.

Diabetes mellitus is a significant risk factor for complications and has been on the rise in recent years. More than 37 million adults in the United States (about 15% of that population) are known to be living with this condition—with potentially more whose condition has gone undiagnosed.

"Heart disease remains the number one killer in the US despite advancements in ," said co-lead investigator Vardhmaan Jain, MD, a doctoral fellow in cardiology at Emory School of Medicine. He added that patients with diabetes mellitus are disproportionately affected by cardiovascular disease.

With an eye toward improving patient outcomes, Jain and other researchers performed an updated epidemiological analysis to define the current magnitude of the problem. They found that diabetes can double or even quadruple the risk of cardiovascular events in patients. Diabetes can also cause a three-fold increased risk of cardiovascular mortality.

The investigators used data from the Centers for Disease Control and Prevention's WONDER (Wide-Ranging Online Data for Epidemiologic Research) database to identify adults aged 25 years and older who died between 1999-2019, where the underlying or contributing cause of death was cardiovascular disease and diabetes.

This analysis revealed additional patterns of mortality over the past 20 years, including:

  • Males and non-Hispanic Black adults were more affected than other demographic subgroups.
  • There was an alarming rise in diabetes and cardiovascular disease-related in younger adults (25-54 years old) and middle-aged adults (55-69) during the latter part of the study period.
  • There was a higher burden of mortality in than in —and this difference widened with the progression of time.
  • Hotspots for higher diabetes and cardiovascular disease-related mortality were evident in Midwestern, Western and Southern states.

The introduction of newer therapies and updated management guidelines have transformed the management of diabetes and in the last two decades, offering the potential to boost individual life expectancies. However, several factors make these developments out of reach for large sections of the country, including rising healthcare costs and pre-existing disparities in access to care.

Increasing levels of hypertension, hyperlipidaemia, obesity, smoking, and lower levels of physical activity have also contributed to these negative trends, and control of these modifiable risk factors may be far from optimal in patients with . "Better population-level control of diabetes may have far reaching positive effects on life expectancy," Jain said.
