Background Obesity is an important risk factor of the development of hypertension and other cardiovascular disease, therefore the aim of present study were: 1. To estimate the rate of patients with hypertension in the population of obese patients referred to Metabolic Disease Outpatient Clinic. 2. To estimate the influence of risk factors such as age and BMI on the development of hypertension in the study population. 3. To estimate the frequency of other components of metabolic syndrome in the population of obese patients with and without hypertension.
Material and methods Data of 4377 obese patients of Metabolic Disease Outpatient Clinic from 2000-2005 years were analyzed. Data such as age, body mass, height and obesity concomitant diseases - type 2 diabetes mellitus, hypertension, dyslipidaemia and ischaemic heart disease were inserted to in advance prepared spreadsheet of Excel programme. Patients were divided on the basis of obtained results into two groups: A - patients with hypertension in anamnesis, B - patients without hypertension in anamnesis. On the basis of measurements of blood pressure made in Outpatients Clinic group B was differentiated into 2 subgroups: NR - patients with new diagnosed hypertension and BN - patients without hypertension.
Results Obese patients in group A and subgroup NR had significantly higher body mass, BMI and age when compared to patients in subgroup BN. Type 2 diabetesmellitus, dyslipidaemia and ischaemic heart disease were observed significantly more frequently in group A and subgroup NR when compared to subgroup BN.
Conclusions 1. Patients with hypertension make up 40.8% of the population of obese patients referred to Metabolic Disease Outpatient Clinic. Hypertension in anemnesis inflicts 24,6% of examined population. Hypertension diagnosed „de novo” occured in 21,5% of patients. 2. Age and BMI are important risk factors of hypertension. 3. Type 2 diabetes mellitus, dyslipidaemia and ischaemic heart disease are observed significantly more frequently in obese patients with hypertension.
