Chronic obstructive pulmonary disease, bronchial asthma and allergic rhinitis in the adult population within the commonwealth of independent states: rationale and design of the CORE study.

Background: Main treatable Chronic Respiratory Diseases (CRDs) like Chronic Obstructive Pulmonary Disease (COPD), Bronchial Asthma (BA) and Allergic Rhinitis (AR) are underdiagnosed and undertreated worldwide. CORE study was aimed to assess the point prevalence of COPD, BA and AR in the adult population of major cities of Commonwealth of Independent States (CIS) countries - Azerbaijan, Kazakhstan, and Ukraine based on study questionnaires and/or spirometry, and to document risk factors, characterize the COPD, BA and AR population to provide a clearer "epidemiological data".

Methods: A descriptive, cross-sectional, population-based epidemiological study conducted from 2013 to 2015 with two-stage cluster geographical randomization.

[The interrelation of the secretory activity of the myocardium with its hypertrophic characteristics in patients with ischemic heart disease].

Evaluation of the concentration of atrial natriuretic peptide, angiotensin P, renin activity in the blood of the coronary sinus and aorta in 18 patients with IHD and hypertrophy of the left ventricle during development of induced ischemia revealed that in left ventricular hypertrophy secretion of atrial natriuretic peptide by the myocardium is reduced. The level of this reduction depends on the kind of hypertrophy. Dilatation of the left ventricle cavity furthers exhaustion of the secretory function of the ischemic myocardium.
