Vascular events involve situations that affect circulatory system - veins, arteries and lymph vessels. Shift work can lead to a variety of health hazards particularly vascular diseases.

The scientists noticed that shift work is considerably linked with ischemic stroke and myocardial infarction. The risk ratio with myocardial infarction was 1.23 and with ischemic stroke was 1.05.
The scientists reported that in contrast to daytime workers, the shift workers had 24 percent high risk for coronary ailments, 5 percent high risk for stroke and 23 percent high risk for heart attack.
There was no association between raised mortality rates and shift work. Adjustment for socioeconomic status and smoking was not a cause of heterogeneity.
In Canada the occurrence of shift work is 32.8 percent and the risk for myocardial infarction were 7 percent, for ischemic stroke the risk was 6 percent and for coronary events the risk was 7.3 percent.
The researchers said, "The increased risk of vascular disease apparent in shift workers, regardless of its explanation, suggests that people who do shift work should be vigilant about risk factor modification."
The experts said that the relative risks were modest but because of the rising frequency of shift work among the general population, the consequences on the public health are not insignificant.
