[Epidemiology of cardiovascular disease in the urban population of the town of Pahlavi (North Iran)]. / Epidemiologie de la maladie cardiovasculaire dans la population urbaine de la ville de Pahlvai (nord de l'Iran)

A survey of cardiovascular diseases was carried out in June-August 1973 in the city of Pahlavi, a port in the Caspian area in Iran. A representative sample was taken from persons aged 35 years and older from both sexes. The prevalence of high blood pressure (WHO definition) is 29,7% in men and 31,0% in women of this age group. ECG tracings were prepared and the prevalence of various abnormalities are presented. A considerable proportion of the population have ST segment and T wave abnormalities. Correlation between ECG abnormalities and blood pressure figures has been studied. This study shows that there is a relationship between ECG abnormalities of group 3, 4 and 5 (Minnesota Coding) and the levels of blood pressure.

[Chronic pulmonary heart disease and its risk factors among a worker population in Teheran]. / Le coeur pulmonaire chronique et ses facteurs de risque dans une population ouvrière de Téhéran

Because of the high frequency of chronic cor pulmonale in workers admitted to the cardiology department of the Khazaneh Hospital in Teheran, we studied the clinical aspect and the risk factors of this disease in 66 male patients. The average age of patients was 56.1 years and they often had a long history of bronchitis isolated or associated with emphysema. The ECG analysis showed that most abnormalities were localized on the QRST wave. Tobacco and a polluted working environment were the factors most frequently met in our patients. The opium habit probably acted as a risk factor for chronic bronchopneumopathy, but further studies are necessary to ascertain the fact.
