Psoriasis and psoriatic arthritis are relatively common immune mediated diseases. The increase in cardiovascular disease associated with psoriatic disease is well established. Interestingly, some studies suggest a stronger link between psoriatic arthritis and cardiovascular disease.
Hypertension is a major risk factor for the development of cardiovascular disease. It is therefore considered an important modifiable risk factor in the development of cardiovascular disease. Previous studies have shown that patients with psoriasis have an increased risk of poorly controlled hypertension. Furthermore, there appears to be an increased prevalence of hypertension in patients with psoriatic arthritis even after adjusting for traditional cardiovascular risk factors.
A group of collaborating physicians from Hospital Universitario Central de Asturias (HUCA), Spain, led by Dr. Ruben Queiro performed an observational cross-sectional study to analyze the comparative prevalence of hypertension in psoriatic disease.
The patient cohort was from a multidisciplinary (rheumatology/dermatology), single center clinic, in a university hospital in Spain. 290 patients with psoriatic arthritis and 310 patients with psoriasis (in the absence of psoriatic arthritis) were included. For the purpose of the study hypertension was defined as 140/90 on two separate days during a one month period or the chronic use of antihypertensive medication.
The study cohort was composed of 324 men and 276 women with a mean age of 53 ± 12 years. The study results showed the following: 144/600 patients had hypertension (24%). The mean age at onset of psoriasis and arthritis was significantly higher in the hypertension population (39 ± 17 in HBP vs. 26 ± 16 years in non-HBP, p < 0.01, 49 ± 17 in HBP vs. 41 ± 14 years in non-HBP, p < 0.01). The mean body weight and BMI were significantly higher in HBP patients (83 ± 16 in HBP vs. 77 ± 15 kg in non-HBP, p < 0.01, 30.2 ± 4.9 in HBP vs. 27 ± 4.4 in non-HBP, p < 0.01).
