Psoriasis and Heart Disease: Linking Skin to Cardiovascular Health
Researchers claim that severe cases of psoriasis can trigger certain conditions, such as atherosclerosis, which may increase the likelihood of developing heart disease.

Psoriasis, a common immune-mediated dermatological condition, is not limited to affecting the skin. Recent research indicates that individuals with psoriasis are at an increased risk of developing heart disease, independent of traditional cardiovascular risk factors. In this article, we will delve into the mechanisms behind this link, explore the ongoing debates in the scientific community, and discuss potential interventions to minimize cardiovascular risks.
The Inflammatory Connection: Unraveling Psoriasis and Heart Disease
Inflammation is a driving force in the development of cardiovascular disease. In the case of psoriasis, the inflammatory response contributes to the growth of plaques in blood vessels, leading to atherosclerosis and an increased risk of coronary artery disease. However, the precise mechanisms linking psoriasis to heart disease are not yet fully understood. Some studies suggest that coronary microvascular dysfunction (CMD), which affects tiny blood vessels supplying the heart, may play a significant role in this association.
Unveiling Coronary Microvascular Dysfunction
CMD is characterized by inflammation, similar to coronary artery disease, but it has distinct pathological mechanisms. Although previous investigations on CMD in people with psoriasis have been limited in scale, a recent study published in the Journal of Investigative Dermatology aimed to replicate and expand upon these findings.
Conventional medical procedures struggle to detect CMD due to its impact on tiny blood vessels. As a result, researchers in this study utilized a measure called coronary flow reserve to identify both coronary artery disease and CMD.

Decoding Coronary Flow Reserve
Coronary flow reserve assesses the dilation capacity of coronary circulation during exertion, indicating the extent to which blood flow to the coronary arteries can increase. In healthy individuals, the coronary flow reserve ranges from 3 to 6, meaning that blood flow can triple when necessary.
A coronary flow reserve score of 2.5 or lower suggests the presence of CMD or coronary artery disease. If routine coronary angiography reveals no evidence of coronary artery disease, CMD becomes the likely explanation.
Study Insights: Connecting Psoriasis Severity and Disease Duration to CMD
In the study, which included data from 448 individuals with psoriasis, approximately 31% exhibited a coronary flow reserve score of 2.5 or lower, indicating CMD. Notably, these individuals did not show any signs of coronary artery disease in follow-up scans. Factors associated with CMD in the psoriasis group included older age, higher BMI, hypertension, and the presence of psoriatic arthritis.
Furthermore, the severity and duration of psoriasis were closely linked to the risk of CMD. As the disease’s severity and duration increased, so did the likelihood of developing CMD.
Implications and the Road Ahead: Preventing Adverse Cardiovascular Outcomes
The results of this study support the theory that systemic inflammation, driven by psoriasis, contributes to CMD. Crucially, there was no association between CMD and traditional cardiovascular risk factors commonly observed in the general population, such as smoking, blood fat levels, or type 2 diabetes.
Studies have consistently shown that low coronary flow reserves predict poorer cardiovascular outcomes in both the general population and individuals with psoriasis. Therefore, the high prevalence of CMD among individuals with psoriasis is likely a significant contributing factor to their increased risk of adverse cardiovascular events, independent of traditional risk factors.
Moreover, the study suggests that addressing psoriasis through early and effective treatment may restore normal coronary flow reserves and potentially prevent future myocardial infarctions and heart failure associated with CMD.
Assessing Cardiovascular Risk and Exploring Treatment Options
Researchers are actively exploring alternative methods for evaluating cardiovascular risk in individuals with psoriasis. For instance, cardiac imaging techniques like coronary artery calcium scoring hold promise in refining risk assessments. Additionally, novel care coordination models are being tested to enhance screening and management of traditional cardiovascular risk factors in psoriasis patients.
While reducing inflammation has shown potential in lowering cardiovascular risk, the efficacy of psoriasis drugs in this regard remains a topic of debate. Tumor necrosis factor (TNF) inhibitors, for example, appear promising, but further research is required to establish a causal relationship.
Treating psoriasis effectively can also have secondary benefits in reducing cardiovascular risk. Improved disease control can lead to healthier lifestyles, reduced social stigma, improved sleep quality, and modified lipid composition or function.
Final Thoughts: A Puzzle Worth Solving
Psoriasis continues to present mysteries and challenges to researchers and medical professionals alike. This study adds another vital piece to the puzzle, shedding light on the connecting pathways between psoriasis, inflammation, and cardiovascular disease.
As we strive to deepen our understanding, it is crucial to recognize the importance of early intervention and effective treatment plans in reducing the risk of cardiovascular events in individuals with psoriasis. By addressing inflammation and optimizing overall health, we can enhance the well-being of those affected by this complex condition.

Q&A Section
Q: What are the traditional cardiovascular risk factors, and how do they differ from the increased risk associated with psoriasis?
A: Traditional cardiovascular risk factors include smoking, age, diabetes, and hypertension. These factors are widely recognized as contributors to heart disease in the general population. However, individuals with psoriasis face an increased risk of heart disease even when these traditional risk factors are absent. The inflammation associated with psoriasis plays a significant role in driving this elevated risk.
Q: Can treating psoriasis effectively reduce the risk of cardiovascular events?
A: Treating psoriasis effectively has the potential to reduce the risk of cardiovascular events. Studies suggest that improving disease control can positively impact cardiovascular health by promoting healthier lifestyles, reducing social stigma, improving sleep quality, and modifying lipid composition or function. Additionally, some evidence indicates that certain psoriasis treatments may directly lower cardiovascular risk. However, more research is needed to establish a clear causal relationship between psoriasis treatment and cardiovascular outcomes.
Q: Besides inflammation, are there other factors contributing to the link between psoriasis and heart disease?
A: While inflammation is a key player in increasing cardiovascular risk, other mechanisms may also contribute to the association between psoriasis and heart disease. For example, lipid dysfunction, tryptophan metabolism, and the impact of psoriasis on sleep quality are areas of ongoing research. These potential factors highlight the complexity of the connection between psoriasis and cardiovascular health, warranting further investigation.
Q: Are there any novel therapeutic approaches being explored to address the increased cardiovascular risk in individuals with psoriasis?
A: Researchers are investigating alternative methods to assess cardiovascular risk in individuals with psoriasis. For instance, advanced cardiac imaging techniques, including coronary artery calcium scoring, hold promise in refining risk assessments. Moreover, novel care coordination models are being tested to improve screening and management of traditional cardiovascular risk factors in psoriasis patients. These evolving approaches aim to mitigate cardiovascular risks and enhance the overall well-being of individuals with psoriasis.
