Trends and Disparities in Cardiovascular-Related Mortality Among Individuals with Psoriasis in the United States (1999-2020)
Background: Psoriasis is a chronic, relapsing inflammatory condition that mostly affects the skin and joints. Recent data indicate that psoriasis is an independent risk factor for myocardial infarction (MI) and contributes to several cardiovascular (CV) risk factors, including metabolic syndrome, smoking, obesity, hypertension, insulin resistance, and dyslipidemia. Our study quantifies cardiovascular-related deaths among psoriasis patients, examines trends over time, and highlights demographic and geographic disparities to better understand the impact of these coexisting conditions.
Methods: Data from the CDC WONDER database was analyzed to identify cardiovascular- related deaths among adults aged 25 and older with psoriasis in the United States from 1999 to 2020. Age-adjusted mortality rates (AAMRs) per 100,000 persons and annual percent change (APC) were calculated and stratified by year, sex, and age group.
Results: Between 1999 and 2020, cardiovascular-related deaths in individuals with psoriasis accounted for 2,353 deaths among adults aged 25 and older in the US. The overall AAMR for cardiovascular-related deaths in psoriasis decreased from 0.87 in 1999 to 0.7 in 2020, with an Average Annual Percent Change (AAPC) of -0.9324 (95% CI: -1.5179 to -0.3276, p < 0.05). A significant decline occurred from 1999 to 2011 (APC: -5.0752; 95% CI: -6.6070 to -3.8388), followed by a notable increase from 2011 to 2020 (APC: 4.8738; 95% CI: 2.9977 to 7.5961). Men exhibited higher AAMRs compared to women. The AAMR for both men and women decreased, with a steeper decline for women from 1999 to 2011 (APC: -5.05) compared to men in the same period (APC: -4.97). Individuals aged 65 and older demonstrated a decline in AAMR from 1999 to 2011 (APC: -5.66), followed by an increase from 2011 to 2020 (APC: 4.69). Individuals aged 35 to 64 did not demonstrate a similar trend, with an APC of 0.48 from 1999 to 2020.
Conclusion: This analysis reveals significant differences in cardiovascular-related mortality rates among individuals with psoriasis. Men had higher mortality rates than women, with a notable decline from 1999 to 2011 followed by an increase from 2011 to 2020. People aged 65 and older showed a similar pattern, while those aged 35 to 64 exhibited stable rates. These findings emphasize the need for targeted interventions to address the increasing mortality rates, particularly in older adults and men, to improve health outcomes for patients with psoriasis.
