“…These results are in agreement with Tuchsen et al [1992] who reported increased hospitalization for ischemic heart disease was seen among workers self employed in textile industry. Kamal et al [1991] were the first to demonstrate more convincing results in ECG pathologic changes in the exposed workers. However, they were unable to relate the values of ECG components to the duration of the exposure to the chemical as well.…”

Background: In the Registrar General's Decennial Supplement for 1951, bronchitis and myocardial degeneration were both responsible for excessive mortality among cotton spinners and chronic rheumatic disease was an important, although relatively rare, cause of death for cotton weavers. Aim of the work: The present study designed to investigate the environmental indicators and risk factors in textile workers that increase risk of cardiac malfunction and personal conventional risk factors in textile workers that increase risk of cardiac malfunction. In addition, the most susceptible persons to cardiac malfunction among the exposed workers in textile job to avoid exposure as preventive measures. Subjects and methods: A cross sectional study that included workers in textile companies mainly the most exposed persons to environmental and conventional risk factors. Subjects were divided into two groups: Group A: included subjects exposed to risk factors insides textile departments [included 120 subjects who fulfilled inclusion criteria]; Group B: included non-exposed subjects in the other departments, as a control group [included 120 subjects]. Inclusion criteria included the following: male subject, age more than 30 years, work period inside factor is more than 5 years and control group not exposed to textile risk factors before. All cases were underwent full history taking, clinical evaluation, laboratory evaluation and ECG examination. Results: There was significant increase of known environmental risk factors(chemical and physical), past history of medical risk factors, smoking, blood pressure, heart rate, lipid profile and ECG abnormalities in study group,

“…Industrial workers who are exposed to chronic low levels of carbon disulfide have a significant increased prevalence of ECG abnormalities (518)(519)(520)(521). Ventricular arrhythmias have been reported among workers with over 20 years of exposure and repolarization disturbances have been evident in workers with 10 to 20 years exposure history (522).…”

“…[10][11][12][13] Some studies showed a positive association between CS 2 exposure and outcome indices measured, while others did not. This discrepancy may be explained by differences in CS 2 exposure (intensity, duration) as well as differences in ethnic background, but a big issue to be solved is that most of the epidemiological studies in recent years were cross-sectional ones, 14 in which temporal association could not be guaranteed, and therefore it is difficult to conclude whether a causal relation exists at a relatively low concentration of CS 2 .…”

Aims: A six year prospective cohort study was conducted to clarify whether the current carbon disulphide (CS 2 ) exposure level is low enough to prevent subclinical health impairment and/or to ameliorate health effects due to previous high exposure. This paper describes the effects on the cardiovascular systems. Methods: The study subjects were 432 male workers exposed to CS 2 and 402 non-exposed workers in Japan, all of whom were examined in 1992-93. A total of 251 CS 2 exposed, 140 formerly exposed, and 359 non-exposed workers participated in the follow up survey (follow up rate 89.9%) in 1998-99. Mean duration of exposure was 19.3 years at the end the study. Mean CS 2 and 2-thiothiazolidine-4-carboxylic acid (TTCA) concentrations were 5.0 ppm and 1.6 mg/g creatinine. Health items examined were serum biochemical indices including lipids and coagulation-fibrinolysis factors, blood pressure, aortic stiffness, ophthalmography, and electrocardiography at rest and after Master's double 2 step test. Potential confounding factors were adjusted for. Results: Incidence of ischaemic findings, defined as Minnesota codes I, IV 1-3 , V 1-3 (at rest and after the load), or receiving treatment for ischaemia, was significantly higher in the exposed workers, especially for the spinning/refining workers (adjusted OR 2.1; 95% CI 1.1 to 4.0) or the highest quartile of six year mean TTCA (adjusted OR 3.9; 95% CI 1.8 to 8.7), although the observed increase in risk was diminished when rigorous ECG criteria were applied. Incidence of retinal microaneurysm was increased with marginal significance. Among cardiovascular risk factors we examined, only blood pressure values were significantly increased in the exposed workers. Conclusions: Increased risk of ischaemic electrocardiogram findings among Japanese viscose rayon workers was observed. Although its clinical significance is to be discussed, the current Japanese occupational exposure limit for CS 2 , 10 ppm, would be high to prevent subclinical cardiovascular effects in this study population.
