Work Intensity and Cardiovascular Disorders

Background: Heavy physical activities could be affected the cardiovascular systems and might be caused cardiovascular disorders. Objective of this study was the effects of heavy manual work on cardiovascular disorders. Methods: It was a review study and was done by research in text and related articles; metabolic equivalent tasks (METs), cardiovascular disorders assessed. Data were analyzed with SPSS 16, t-test, ANOVA and Chi-2 were calculated with considering P<0.05 as significant level. Relative risks were calculated with confidence interval 95%. Results: Arrhythmia, varicose veins, unstable angina and stable angina were the most in heavy workers. Relative risks were the most in heavy physical activities for arrhythmia and relative risk of varicose veins. Conclusions: Heavy physical activities could be caused arrhythmia and varicose veins and may be related to unstable angina and stable angina too. Prevention and suitable exercises should be useful in this situation.
