OBJECTIVES: Increased frequency of atrial fibrillation (AF) has been demonstrated in psoriasis cases. Prolongation of the duration of atrial electromechanical delay (AEMD) is a well-known characteristic of the atrium, which is vulnerable to AF. In the current study, our aims are to investigate AEMD durations and mechanical functions of the left atrium (LA) in patients with psoriasis.
METHODS: A total of 90 patients, 45 with psoriasis vulgaris and 45 as the control group, were included in the study. Atrial electromechanical coupling (PA) and intra- and inter-atrial electromechanical delay (IA-AEMD) were measured with tissue Doppler echocardiography. P-wave dispersion (PWD) was calculated from the 12-lead electrocardiogram. The severity of the disease was evaluated by the Psoriasis Area and Severity Index.
RESULTS: The durations of PA lateral and PA septal were significantly high in the psoriasis group when compared with the control group (47.7 ± 9.8 vs. 57.1 ± 8.4 msec, P < 0.001 and 38.6 ± 9.9 vs. 43.6 ± 8 msec, P = 0.016, respectively). The durations of IA-AEMD, intra-right electromechanical delay, and intra-left electromechanical delay in the psoriasis group were significantly prolonged compared with the control group (15.2 ± 4.1 vs. 21.7 ± 5.6 msec, P < 0.001; 6 ± 2.5 vs. 8.7 ± 2.7 msec, P < 0.001; and 9.1 ± 3.9 vs. 13.5 ± 5.2 msec, P < 0.001; respectively). PWD was significantly higher in patients with psoriasis vulgaris compared with controls (36.1 ± 7.9 vs. 40.2 ± 9.1 msec, P = 0.043).
CONCLUSION: In the present study, we found prolongation in the durations of AEMD and PWD in the psoriasis group compared with the control group. These results might be an early predictor of AF and other arrhythmias.
