The authors adduce a detailed analysis of the reasons for ST segment elevation, which is found in patients with various pathologic conditions and in some normal individuals, basing this analysis on their own experience and literature data. The authors pay special attention to differential ECG-diagnostics of ST elevation, which plays the most significant part in practice.

Validity of criteria of so called "pulmogenic hypertension" in chronic obstructive pulmonary diseases was assessed with the use of a questionnaire and simultaneous 24 hour monitoring of blood pressure and peak expiratory rate in 80 and 28 patients, respectively. This method of bifunctional monitoring allowed to study relationship between blood pressure level and degree of bronchial obstruction. The results did not confirm the presence of "pulmogenic hypertension" as a special form of arterial hypertension.
AIM: To study incidence rate, course features, principles of diagnosis and therapy of ischemic heart disease (IHD) in patients with chronic obstructive pulmonary diseases (COPD). MATERIALS AND METHODS: Standard clinical examinations, ECG, chest x-ray, echo-CG, 24-h Holter monitoring, coronarography were performed in 60 patients over 40 years of age with bronchial asthma or chronic obstructive bronchitis. Autopsy data were analyzed for 20 patients who died of COPD. RESULTS: IHD was diagnosed in 53.3% of the examinees. 70% of the patients treated with preductal (trimetasidine) benefited from the treatment: they had less frequent episodes of painless myocardial ischemia. Autopsy material has shown that COPD patients frequently suffer of aortic and coronary atherosclerosis. CONCLUSION: IHD diagnosis in COPD patients is rather difficult as there are no well-defined correlations between clinical picture of IHD and data of device investigations, IHD is painless more frequently than in general population (in 84.4% of patients in this study). Preductal is a drug of choice for treatment of IHD in COPD patients.

Examination of 102 patients who developed bronchitis due to exposure to cotton dust running a complicated or noncomplicated course recognized a moderate hyperkininemia in 40% of cases (4.46 +/- 0.43 against the normal 2.90 +/- 0.42) and apparent hypokininemia in 60-63% of cases (0.52 +/- 0.03 against 2.90 +/- 0.42). Hypokininemia appeared in association with pathological shifts in external respiration and central hemodynamics. It is an unfavourable factor contributing to formation of occupation complications of chronic bronchitis: pulmonary emphysema, pulmonary hypertension and cor pulmonale.
The article deals with current issues and quality of the medical labour examinations (MLE) performed by MLE commissions, reveals the reasons accounting for discrepancies in MLE based on the data of the commissions and those of specialized clinics. A clinico-functional examination of 243 in-patient dust bronchitis cases established a late primary diagnosing of dust bronchitis as one of the reasons for invalidism. 3-rd group invalids were mostly workers with lengthy professional background but still before the retirement age, who needed social and labour rehabilitation. The main reason for the discrepancies lies in inadequate examination prior to the MLE commissions decision and prescription of invalidism to the patients with the initial stage of the disease basing on the social criterion.
