Comparative Study
[Peculiarities of atherosclerotic injury of carotid arteries in patients with coronary artery disease with hyperhomocysteinemia].
Peculiarities of atherosclerotic injury of carotid arteries were studied in 47 patients with coronary artery disease in dependence of blood concentration of homocysteine. The patients were divided in 2 groups -- with homocysteine concentration more and less than 10 mmol/l, and in 4 groups, corresponding to quartiles of distribution of homocysteine in blood. ⋯ It was established that elevation of blood homocysteine concentration was accompanied with increase of IMT, number of atherosclerotic plaques, and. Positive correlation was found between homocysteine level and IMT (r=0.38, p<0.05), degree of narrowing of carotid arteries (r=0.47, p<0.05), character of atherosclerotic plaques (r=0.43, p<0.05).

In a series of articles the authors discuss literature data concerning epidemiology of pulmonary hypertension, its modern classification; peculiarities of its pathogenesis and treatment in various diseases and conditions. In the forth lecture they present literature data on prevalence of chronic cor pulmonale among patients with congestive heart failure and its value for prognosis. ⋯ Pathogenetic mechanisms of right ventricular failure in COPD and the role of interaction of hemodynamic, renal, and neuro-humoral factors in pathogenesis of edematous syndrome in patients with chronic cor pulmonal are presented. The article also contains discussion of possibilities and limitations of clinical and instrumental diagnostics of pulmonary hypertension and right ventricular failure in patients with COPD.

In a series of articles the authors discuss literature data concerning epidemiology of pulmonary hypertension, modern classification; peculiarities of its pathogenesis and treatment in various diseases and conditions. In the second part they consider peculiarities of pathogenesis of pulmonary hypertension and right ventricular failure in patients with predominant involvement of left cardiac chambers. Effects of various classes of drugs used in the treatment of left ventricular heart failure including their influence on pulmonary circulation and functional state of the right ventricle are also discussed.
