Insights
Mortality from cardiovascular diseases (CVDs) and thyroid disorders combined is rising in US adults. This trend underscores the urgent need for better monitoring and prevention strategies for these interconnected conditions.
Area of Science:
- Cardiovascular Medicine
- Endocrinology
- Public Health Epidemiology
Background:
- Thyroid disorders are significant contributors to cardiovascular diseases (CVDs) in the U.S.
- Existing data lacks specific trends on CVD-related mortality in patients with thyroid disorders.
- Understanding these combined impacts is crucial for public health initiatives.
Purpose of the Study:
- To analyze trends in CVD-related mortality among adults with coexisting thyroid disorders in the U.S. from 1999 to 2023.
- To identify demographic and geographic patterns associated with this mortality.
- To inform targeted public health interventions.
Main Methods:
- Retrospective analysis of the CDC Wide-Ranging Online Data for Epidemiologic Research (WONDER) database.
- Inclusion of adult deaths (≥25 years) with recorded CVD and thyroid disorders from 1999-2023.
- Calculation of age-adjusted mortality rates (AAMRs) and annual percent change (APC), stratified by demographics and region.
Main Results:
- Over 513,000 deaths were recorded due to combined CVD and thyroid disorders.
- Ischemic heart disease was the leading cause (59.43%).
- Overall AAMR increased from 8.63 in 1999 to 10.82 in 2023 (APC 0.76).
- Higher AAMRs were observed in women, non-Hispanic White individuals, the Midwest region, and nonmetropolitan areas.
- Wyoming, Nebraska, Oklahoma, South Dakota, and West Virginia showed the highest mortality rates.
Conclusions:
- A significant rise in mortality among U.S. adults with coexisting CVD and thyroid disorders was observed between 1999 and 2023.
- The increasing trend highlights the critical need for enhanced surveillance and proactive prevention strategies.
- Integrated approaches to managing these interconnected conditions are essential.
Abstract:
Thyroid disorders substantially contribute to cardiovascular diseases (CVDs) in the United States. Although current U.S. data provides general mortality rates attributed to these diseases individually, trends specific to CVD-related mortality among patients with thyroid disorders remain underexplored. We examined the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research database for deaths related to concomitant CVD and thyroid disorders among adults aged ≥25 years from 1999 to 2023. Age-adjusted mortality rates (AAMRs) per 100,000 with 95% confidence intervals (CIs) and annual percent change (APC) were calculated and categorized by demographics and geographic region. A total of 513,974 deaths were recorded due to CVD and thyroid disorders. Ischemic heart disease reported the highest burden in these patients, with a total of 305,497 deaths (59.43%). The AAMR observed a significant incline from 8.63 in 1999 to 10.82 in 2023, with an average APC of 0.76 (95% CI: -0.16 to 1.69). Women had consistently higher AAMRs than men (10.96 vs 6.22). Racially, non-Hispanic (NH) White population had the highest overall AAMR (9.74). Regionally, the Midwest recorded the highest overall AAMR (9.91). A higher overall AAMR was observed in Nonmetropolitan areas as compared to metropolitan areas (10.84 vs 8.41). States that fell in the top 90th percentile were Wyoming, Nebraska, Oklahoma, South Dakota, and West Virginia. In this retrospective analysis spanning from 1999 to 2023, we identified a notable rise in mortality among adults with coexisting CVD and thyroid disorders. The concurrent escalation in both prevalence and mortality highlights the pressing need for strengthened surveillance, proactive prevention, and therapeutic interventions.

Synthesis and Regulation of Thyroid Hormones
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The iodine is then...
