New York: The way a person reacts to stressful events in life holds greater importance in terms of health as compared to the frequency with which one encounters it.

According to the researchers, the more negatively an individual perceives and reacts to a situation the more he/she may be at risk of developing heart disease.

The team wanted to find out whether daily stress and heart rate variability, a measure of autonomic regulation of the heart, are linked.

A potential pathway that links stress to future heart disease is a dysregulation of the autonomic nervous system- a case of a person’s normally self-regulated nervous system getting off track.

“Higher heart rate variability is better for health as it reflects the capacity to respond to challenges,” said Nancy L Sin from Pennsylvania State University.

“People with lower heart rate variability have a greater risk of cardiovascular disease and premature death,” Sin added in the paper published in the journal Psychosomatic Medicine.

Depression and major stressful events are known to be harmful to health, but less attention has been paid to the health consequences of frustrations and hassles in everyday life.

The team analysed the data collected from 909 participants between the ages of 35 and 85, including daily telephone interviews over eight consecutive days and the results from an electrocardiogram.

During daily phone interviews, participants were asked to report the stressful events as well as negative emotions they had experienced that day.

The researchers found that participants who reported a lot of stressful events in their lives were not necessarily those who had lower heart rate variability.

No matter how many or how few stressful events a person faces, it was those who perceived the events as more stressful or who experienced a greater spike in negative emotions had lower heart rate variability- meaning these people may be at a higher risk for heart disease, the authors noted. (IANS)

Eating Eggs May Keep Heart Diseases Away

If you thought eating eggs is bad for your heart due to their high cholesterol content, think again. A large study has now shown that people who consume an egg every day could significantly reduce their risk of cardiovascular diseases.

People suffering from diabetes may finally eat eggs daily without a pinch of guilt. A new study suggests that eating up to 12 eggs a week does not increase cardiovascular risk factors in people with pre-diabetes or Type-2 diabetes.

If you thought eating eggs is bad for your heart due to their high cholesterol content, think again. A large study has now shown that people who consume an egg every day could significantly reduce their risk of cardiovascular diseases.

“The present study finds that there is an association between moderate level of egg consumption (up to one egg/day) and a lower cardiac event rate,” the study authors said.

The researchers pointed out that eggs are a prominent source of dietary cholesterol, but they also contain high-quality protein, many vitamins and bioactive components such as phospholipids and carotenoids.

Cardiovascular disease (CVD) is the leading cause of death and disability worldwide mostly due to ischaemic heart disease and stroke (including both haemorrhagic and ischaemic stroke).

For the study, published in the journal Heart, Chenxi Qin from Peking University Health Science Centre in Beijing, and colleagues set out to examine the associations between egg consumption and cardiovascular disease, ischaemic heart disease, major coronary events, haemorrhagic stroke and ischaemic stroke.

They used data from the China Kadoorie Biobank (CKB) study, an ongoing prospective study of around half a million (512,891) adults aged 30 to 79 from 10 different geographical areas in China.

The researchers focused on 416,213 participants who were free of prior cancer, cardiovascular disease (CVD) and diabetes.

Analysis of the results showed that compared with people not consuming eggs, daily egg consumption was associated with a lower risk of CVD overall.

In particular, daily egg consumers (up to one egg per day) had a 26 per cent lower risk of haemorrhagic stroke, a 28 per cent lower risk of haemorrhagic stroke death and an 18 per cent lower risk of CVD death.

In addition, there was a 12 per cent reduction in risk of ischaemic heart disease observed for people consuming eggs daily, when compared with the ‘never/rarely’ consumption category — about 2.03 eggs per week.

This was an observational study, so no firm conclusions can be drawn about cause and effect, but the authors said their study had a large sample size and took into account established and potential risk factors for CVD. (IANS)
