Avaliação dos fatores de risco para aterotrombose em pacientes com doença pulmonar obstrutiva crônica em oxigenoterapia

Abstract

The present study evaluated the frequency of major risk factors for atherothrombosis in patients with Chronic Obstructive Pulmonary Disease (COPD) in oxygen in both gender. The sample consisted of 62 individuals, 28 men and 34 women, mean age 71.8 ± 8.7 years, all members of the Home Care Program, Hospital de Clinicas, Universidade Federal de Uberlândia. COPD was diagnosed when there were clinical signs and symptoms with changes in spirometry [(Forced Expiratory Volume in one second by forced vital capacity (FEV1/FVC) &#8804; 0.7 boncodilatador post (BD)]. All subjects received regular treatment with inhaled corticosteroids, Tiotropium and ß-2 agonist with long duration. We evaluated the following risk factors for atherothrombosis: body composition [(body weight, body mass index (BMI) and waist to hip index (WHI)], fasting plasma glucose, plasma lipid profile [(Total Cholesterol (TC), HDL-cholesterol (HDL-C) and triglycerides (TG)], smoking and tobacco intake, sedentary lifestyle, blood pressure at rest, C-reactive protein highly sensitive (hsCRP), forced expiratory volume in first second (FEV1), heart rate (HR), hypoxemia and calculation of Framingham risk score (FRS). The statistical analysis used SPSS 13.0 for Windows and BioEstat 5.0. Mean comparisons were made using T test and U test of Mann-Whitney, adopting, as significant, p values <0.05. At final evaluation, it was observed that all subjects were sedentary, the rate of type 2 diabetes mellitus (T2DM) was 11.3%, the rate of hypertension (HBP) was 41.9% and 19.4% of the subjects smoked actively. The mean HR was 82.8 ± 13.9 bpm; partial pressure of oxygen in the blood (PO2) found the average was 48.4 ± 8.8 mmHg, the mean FEV1 was 35 ± 15%, median hsCRP was found to be 6.5 ± 13.6 mg / l. The average weight (kg) was 59, 3 ± 15.3, BMI 24.4 ± 5.5 and ICQ 1.0 ± 0.1. The ERF was below average in this population, probably by correcting hypoxemia and oxygen provided by the appropriate treatment of COPD . The elevated serum levels of TG, TC, LDL-C and fasting glucose, and presence of high levels of blood pressure and smoking were equally distributed in both gender. Serum HDL-C were significantly lower in men. Variables such as hsCRP, FC, and PO2 were also equally distributed between men and women, except for the FEV1, lower in men. Men had higher ERF (higher risk for MI or death in 10 years) and low HDL-C in men contributed decisively to this finding. FEV1 reduced CRP levels and hypoxemia characteristics were found across the sample, and these items are included in the risk factors for atherothrombosis.
