Frequency of fragmented QRS in patient with psoriasis vulgaris without cardiovascular disease

Myocardial fibrosis causes the fragmentation of QRS complexes on electrocardiogram. We hypothesized that the frequency of fragmented QRS (fQRS) could be more common in patients with psoriasis vulgaris than in healthy control subjects. In this prospective study, 100 patients with psoriasis vulgaris who did not have any cardiovascular disease were compared with 50 healthy volunteers in control group. The Psoriasis Area Severity Index (PASI) was used for expressing the severity of psoriasis. Patients with psoriasis were categorized according to presence of fQRS in ECG [fQRS (+) group and fQRS (−) group]. Patients with psoriasis had higher frequency of fQRS, higher levels of C reactive protein (CRP) and sedimentation rate (ESR) than the control group ( n = 49, 49 % vs. n = 3, 6 %, p
