CARDIOVASCULAR RISK FACTORS IN PATIENTS WITH CHRONIC OBSTRUCTIVE PULMONARY DISEASE
Abstract
Objective: to detect previously undiagnosed arterial hypertension in patients with chronic obstructive pulmonary disease (COPD) as a risk factor for cardiovascular mortality.
Materials and methods. 43 patients with stage I–II of COPD and the absence of clinical signs of cardiovascular diseases were examined. Spirometry, body plethysmography and diffusing lung capacity (DLCO) were included in the respiratory system assessment. The cardiovascular system was assessed with echocardiography and ambulatory blood pressure monitoring (ABPM).
Results. Despite the absence of obvious signs of cardiovascular lesions (an increase of office blood pressure, intracardiac hemodynamic changes), the following cardiovascular risk factors were identified: age (58.2 ± 2.0 years), male gender, smoking, hypercholesterolemia and dyslipidemia (total cholesterol 5.9 ± 0.9 mmol / l, low density lipoproteins 3.8 ± 0.5 mmol / l, triglycerides 1.8 ± 0.2 mmol / l). Correlation analysis has revealed the relation between several respiratory parameters and the severity of dyspnea and quality of life in patients with COPD, as well as its relation with lipid levels.
Conclusion. The patients with COPD have a large number of risk factors for CVD. According to ABPM data, arterial hypertension was verified in 18 (41.9 %) of 43 patients with COPD at normal level of office blood pressure; moreover, 51.2 % of patients demonstrated low reduction of blood pressure during the night-time that nowadays, is considered to be a predictor of cardiovascular disease and sudden death.

CAROTID ATHEROSCLEROTIC LESION IN YOUNG PATIENTS
Abstract
Objective: to determine the incidence of atherosclerotic lesions in the carotid and vertebral arteries of young patients from Doppler ultrasound data and to compare the quantitatively assessed traditional risk factors of coronary heart disease (CHD) with severe extracranial artery atherosclerotic lesion.
Subjects and methods. Doppler ultrasound was carried out evaluating structural changes in the aortic arch branches in 1563 railway transport workers less than 45 years of age. A separate sample consisted of 68 young people with carotid atherosclerotic changes, in whom traditional risk factors for CHD were studied, so were in a control group of individuals without atherosclerotic changes (n = 38).
Results. Among the examinees, carotid atherosclerotic lesion was detected in 112 (7.1 %) cases, the increase in the rate of atherosclerotic plaques in patients aged 35–45 years being 9.08 %; that in the rate of local intima-media thickness in those aged 31–40 years being 5.1 %. Smoking (particularly that along with hypercholesterolemia and a family history of cardiovascular diseases), obesity (along with low activity), and emotional overstrain were defined as important risk factors in the young patients. Moreover, factor analysis has shown that smoking,
hypertension, and early cardiovascular pathology in the next of kin makes the greatest contribution to the development of carotid atherosclerotic lesion.
Conclusion. Among the patients less than 45 years of age, carotid and vertebral artery atherosclerotic changes were found in 112 (7.1 %) cases, which were more pronounced in male patients. Smoking, particularly along with hypercholesterolemia and genetic predisposition to cardiovascular diseases, was a risk factor that had the highest impact on the degree of atherosclerotic lesion in the aortic arch branches of the young patients.
