Increased prevalence of early repolarization in electrocardiograms of psoriatic patients.

Psoriasis (Ps) is a chronic-relapsing, inflammatory, and proliferative condition of the skin: prior studies hypothesized a link between Ps and anomalies in ß-adrenergic tone. We therefore aimed to ascertain the prevalence of early repolarization pattern (ERP) in resting electrocardiograms (ECGs) of psoriatic patients compared with an appropriate control group. We performed a retrospective study of resting ECGs of 100 consecutive psoriatic patients and 100 healthy controls. The presence of ERP in at least two contiguous leads at rest ECG was recorded, and findings were also categorized according to the lead group where ERP was detected (anterior, lateral, inferior). An ERP in ≥ 2 contiguous leads occurred in 40 % of psoriatic patients, compared with 14 % of control subjects (p < 0.001). (36 vs 10 % in anterior leads, p < 0.001; 6 vs 3 % in inferior leads, p n.s.; 10 vs 2 % in lateral leads). After adjustment for sex, age, heart rate, and level of physical activity, the odds ratios for the presence of ERP were 8.6 (95 % CI, 2.1-35.2, p < 0.01), and 7.1 (95 % CI, 1.6-31.8, p < 0.05) in anterior leads. In a small case/control study, increased rates of ECGs showing ERP have been observed among psoriatic patients. Clinical significance of such finding needs to be assessed in further observational studies.

Cardiovascular sequelae of radiation therapy.

Radiotherapy (RT) is one of the main therapeutic options for malignancy treatment; nevertheless, RT is not free from side effects, including an increased risk for secondary neoplasms and other organs injury. Cardiovascular complications are the second most frequent fatal post-RT sequelae, which physicians should be aware of and ready to diagnose early and cure. This review therefore aims to examine epidemiology, pathogenesis and clinical dose-correlated manifestations of RT-induced cardiovascular disease. Future perspectives on screening, prevention and treatment are also provided.
