Prevalence of cardiovascular disease in subjects hospitalized due to chronic obstructive pulmonary disease in Beijing from 2000 to 2010

Objectives To investigate the overall prevalence of cardiovascular disease （CVD） in subjects hospitalized for chronic obstructive pulmonary disease （COPD）,and explore the prevalence of the major CVD complications and trends in patients with COPD over a 10-year period.Methods Medical records in the PLA General Hospital,Beijing Union Medical College Hospital,and Beijing Hospital from 2000/01/01 to 2010/03/03 were retrospectively reviewed.A total of 4960 patients with COPD were reviewed in the study （3570 males,mean age,72.2 ± 10.5 years; 1390 females,mean age,72.0 ± 10.4 years）.Results The prevalence of CVD in COPD patients was 51.7％.The three most prevalent CVDs were ischemic heart disease （28.9％）,heart failure （19.6％）,and arrhythmia （12.6％）.During the 10-year study period,the prevalence of various CVDs in COPD patients showed a gradual increasing trend with increasing age.There was higher morbidity due to ischemic heart disease （P ＜ 0.01） in male COPD patients than in the female counterparts.However,heart failure （P ＜ 0.01）and hypertension （P ＜ 0.01） occurred less frequently in male COPD patients than in female COPD patients.Furthermore,the prevalence of ischemic heart disease decreased year by year.In addition to heart failure,various types of CVD complications in COPD patients tended to occur in younger subjects.The prevalence of all major types of CVD in women tended to increase year by year.Conclusions The prevalence of CVD in patients hospitalized for COPD in Beijing was high.Age,sex and CVD trends,as well as life style changes,should be considered when prevention and control strategies are formulated.

Classical regression equations of spirometric parameters are not applicable for diagnosing spirometric abnormalities in adipotic adults

The prevalence of overweighing and obese adults (defined as "adipotic" adults),has markedly increased over the world. A remarkable increase in the adipotic population urgently needs developing the regression equations for predicting spirometric parameters (SPs), which are specifically applicable to adipotic adults.Unfortunately, however, the reliable equations suitable for adipotic adults have not been reported to date. Recently, Yamaguchi et al have proposed the quantitative method to estimate the effects of adiposity on deciding the SPs incorporating with age-specific contributions of various explanatory,independent variables such as age (A), standing height (H), body weight (BW),and fat fraction of body mass(F). Extending the method proposed by Yamaguchi et al, we attempted to elaborate the novel regression equations applicable for diagnosing the spirometric abnormality in adipotic adults. For accomplishing this purpose, never-smoking, adipotic adults with body mass index (BMI) over 25 kg/m^2 and no respiratory illness were recruited from the general population in Japan (n = 3696, including men: 1890 and women: 1806). Introducing the four explanatory variables of A, H, BW, and F, gender-specific and age-dependent regression equations that allowed for prescribing the SPs in adipotic adults were constructed. Comparing the results obtained for non-adipotic adults (i.e., those with normal BMI), the negative or positive impact of height on SPs was preserved in adipotic adults, as well. However, the negative impact of age on SPs was blunted in adipotic men and the positive effect of BW on SPs was impeded in adipotic men and women. The fat fraction of body mass-elicited negative impact on SPs vanished in adipotic women. These results indicate that the regression equations of SPs for adipotic adults differ significantly from those for nonadipotic adults, leading to the conclusion that the regression equations for nonadipotic adults should not be used while judging the spirometric abnormalities in adipotic adults.

Condition Metabolic Balance Disturbance in Patients with Cor Pulmonale： Prevalence, Diagnosis, Risk Factors

To study the risk factors for the development of cor pulmonale （CP） in patients with chronic pulmonary diseases in the Republic of Uzbekistan, the disbalance in parameters of stable metabolites oxides of the nitrogen （SMNO）, of blood oxygen saturation （SaO2）, of respiratory function and on lipid peroxidation of cell membrane were measured. The authors evaluated the effect of base therapy and ozone therapy （OT） in patients with CP. Basis therapy and OT resulted in good parameters of SMNo, SaO2 and metabolic activeness of cell, significant positiveness of hypoxemia and parameters of pulmonary ventilation ability and hemodynamics of pulmonary arteria.
