Well-controlled psoriasis still carried 2.8 times more heart dysfunction
In short
In a cross-sectional comparison of 1,010 adults with psoriasis against 1,010 age- and sex-matched controls, myocardial dysfunction defined as global longitudinal strain below 16% was present in 16.7% of the psoriasis group versus 6.0% of controls (p < 0.001). The association persisted after adjustment for cardiometabolic risk factors and atherosclerotic cardiovascular disease, and cardiac structure and function were largely similar across psoriasis severity. Within the psoriasis group, higher body mass index and diabetes were independently associated with myocardial dysfunction.
That chronic inflammatory disease raises cardiovascular risk was already established. The question this study narrowed is whether that risk actually shows up in cardiac structure and function.
1,010 adults with psoriasis from the prospective PSOCADIA cohort and 1,010 age- and sex-matched controls without inflammatory skin disease underwent transthoracic echocardiography, assessed for hypertrophy, valvular disease, systolic and diastolic dysfunction, and myocardial dysfunction defined as global longitudinal strain below 16%.
How large was the gap?
Abnormal GLS: 16.7% in psoriasis against 6.0% in controls (p < 0.001) — roughly 2.8-fold. And the association persisted after adjustment for cardiometabolic risk factors and atherosclerotic cardiovascular disease. Strip out the share explained by obesity, hypertension, and diabetes, and a difference remained.
Doesn't clear skin mean it is handled?
This is the uncomfortable part. Participants had well-managed skin disease, and cardiac structure and function were largely similar across psoriasis severity. The visible marker does not tell you what the heart is carrying. It runs in the same direction as depression predicting heart wall thickening: a load that leaves a structural trace without announcing itself.
So what is actually adjustable?
Within the psoriasis group, the factors independently associated with myocardial dysfunction were higher body mass index and diabetes. Psoriasis is not a choice; those two are. On the dose relationship between exercise and inflammatory markers, see the exercise dose that lowers inflammation; on combined aerobic and resistance work producing the largest CRP reduction, combined training lowers CRP most; on glucose, the exercise dose for blood sugar.
The training implication is modest but clear. If you train with a chronic inflammatory condition, body composition and glucose control are cardiac targets, not cosmetic ones. The Muscle Index normalises your lifts to your bodyweight — it is not an argument to weigh less, but body fat and blood glucose are numbers to watch separately from the bar.
This is a cross-sectional analysis comparing two groups at one point in time. It does not establish that psoriasis causes myocardial dysfunction, and it cannot order the two in time. Global longitudinal strain is not part of a routine check-up, and whether it is warranted is a clinical decision.
Frequently asked questions
How much more common is cardiac dysfunction in psoriasis?
Comparing 1,010 adults with psoriasis to 1,010 age- and sex-matched controls, myocardial dysfunction defined as global longitudinal strain below 16% was present in 16.7% versus 6.0% (p < 0.001) — about 2.8 times as common.
Isn't this just obesity and diabetes?
Not entirely. The association persisted after adjustment for cardiometabolic risk factors and atherosclerotic cardiovascular disease. Within the psoriasis group, however, higher body mass index and diabetes were independently associated with myocardial dysfunction.
Does worse psoriasis mean a worse heart?
Not in this study. Cardiac structure and function were largely similar across psoriasis severity, and the elevated rate of myocardial dysfunction was present even though participants' skin disease was well managed.
What does global longitudinal strain measure?
It is an echocardiographic measure of how much the myocardium shortens along its long axis. This study defined values below 16% as myocardial dysfunction; abnormal strain can appear while ejection fraction still reads normal.
What can actually be changed on the basis of this?
Psoriasis itself is not modifiable, but body mass index and diabetes are, and those were the two factors independently associated with myocardial dysfunction here. The design is cross-sectional, so it shows association rather than cause.
