Psoriasis Linked to 24% Increased Stroke Risk, Especially in Severe Cases

This meta-analysis systematically reviewed 18 observational studies comprising 705,602 psoriasis patients and 17,971,569 controls to assess stroke risk associated with psoriasis. Using a random-effects model, the pooled hazard ratio (HR) for stroke in psoriasis patients was found to be 1.24 (95% confidence intervals [CI]: 1.15-1.35, P<.05), indicating a 24% increased risk compared to controls. Stratification by disease severity revealed that patients with mild psoriasis had an HR of 1.09 (95% CI: 1.02-1.16), while those with severe psoriasis had a significantly higher risk with an HR of 1.36 (95% CI: 1.21-1.53). Regional analysis showed varying risk levels, with HRs of 1.08 in Asia, 1.26 in Europe, and 1.49 in North America. Age subgroup analysis confirmed the association across different age groups. No specific safety or adverse event data were reported in the meta-analysis. Clinically, these findings underscore the necessity for comprehensive cardiovascular risk management in psoriasis patients, particularly those with severe disease, to mitigate stroke risk. Further research is warranted to elucidate the mechanisms driving this increased risk.

This study focuses on psoriasis, a long-lasting skin condition that affects about 2% to 3% of people worldwide. Researchers looked at many studies to understand if having psoriasis increases the risk of having a stroke, which is when blood flow to the brain is blocked. They found that people with psoriasis are more likely to have a stroke, and this risk is even higher for those with severe psoriasis and older individuals. This means that if you have psoriasis, especially in a severe form, it’s important to talk to your doctor about your heart health and stroke risk. However, it’s also important to remember that while this study shows a link, it doesn’t explain why this happens. More research is needed to understand the reasons behind this increased risk.
