Subclinical cardiovascular disease and it's improvement after long‐term TNF ‐α inhibitor therapy in severe psoriatic patients

BACKGROUND: There are conflicting data on the occurrence of subclinical myocardial dysfunction in psoriatic patients and on the impact of long-term tumour necrosis factor-alpha (TNF-α) inhibitor therapy on cardiac function. OBJECTIVE: In this study, we explored whether there are any signs of subclinical cardiovascular disease (echocardiographic abnormalities) in severe psoriatic patients without clinically overt heart disease. As a second objective, the influence of long-term treatment with TNF-α inhibitors on the ventricular functions of psoriatic patients was also investigated. METHODS: Clinical and echocardiographic data from 44 psoriatic patients and 45 age- and sex-matched controls were processed. As a first step, the echocardiographic parameters of psoriatic patients obtained before anti-TNF-α treatment were compared with controls. As a second step, to detect the effect of long-term anti-TNF-α treatment on echocardiographic parameters, data of patients before and after therapy were analysed. RESULTS: The right ventricular Tei index was higher (P < 0.001), whereas the tricuspid annular plane systolic excursion (TAPSE) and right ventricular free wall peak systolic velocity were lower (P < 0.001 and P < 0.0001, respectively) in the psoriatic patients than in the controls. Following treatment with TNF-α inhibitors, TAPSE and right ventricular free wall peak systolic velocity significantly improved (P < 0.0001 for both parameters). The Tei index of both ventricles improved during biological therapy; however, this change did not reach statistical significance. CONCLUSION: Patients with severe psoriasis exhibit signs of subclinical cardiovascular disease compared to control, and prolonged anti-TNF-α therapy has a potentially beneficial effect on these signs.
