It is not a surprising fact that people nowadays are more indulge in activities at late hours such as doing night shifts of the office. It has been revealed that people working at night are more prone to heart disorders. They have a high chance of heart-attack and other problems related to the heart.

This has been revealed in the European Heart Journal. Let us find out some interesting facts related to it.

About study

According to the European Heart Journal's findings, people who work late at night are more prone to a high risk of heart problems. They have a risk of increasing the irregular and abnormally fast heart rate rhythm which is known as arterial fibrillation (AF).

This is the first study conducted about AF and the night working habits of people. This research has been done on 2,83,657 people in the United Kingdom database system.

Who all are involved?

This research has been successfully conducted by the researchers. The researchers were supported by a team of professionals. It includes Professor Yinbgli Lu of Shanghai Ninth People’s Hospital and Shanghai Jiao Tong University School of Medicine. Besides these, professors of JiaoTong University School of Medicine, Shanghai, China and Professor Lu Qi of Tulane University School of Public Health and Tropical Medicine, New Orleans, USA were also there in the research panel.

The team of researchers with professionals had investigated a genetic predisposition. They wanted to find out that whether this genetic predisposition to AF is responsible for increase heart risk disorders. The evaluation had been done on overall genetic risk on about 166 genetic variants which are known to be associated with this condition.

Results and findings

After completing research, it was found that the genetic risk levels are not going to affect the link between working night habits and AF risk of individuals. It is regardless of whether any person has a low, medium or high risk of heart disorders.

After adjusting various factors such as age, gender, sex, education, socio-economic conditions, smoking, diet, body mass index, sleep status, chronotype of people, it was seen that people working in night shifts permanently had a 12 percent increase rate of AF as those working in the night. Also, it increases to 18 percent after ten more years of working at night.

According to Professor Lu, this study included around 1,86,353 people who were in the paid employment services or were self-employed. Total participants of 2,83,657 did not had AF when they successfully enrolled themselves in the UK bio tank. Also, 2,76,009, participants are not reported to have heart failure stroke.

The information on variants of genes was available for 1,93,819 people without AF while 75,391 of them were sent in-depth questionnaires in 2015 for their lifetime employment. When joined the study, around 73,986 people provided information about their employment history. Over ten years of taking follow-up, around 5,777 cases were related to AF.
