Cardiologists have found out how irregular sleep affects heart health American cardiologists conducted a study to determine how irregular sleep duration affects the human cardiovascular system. As it turned out, such a common habit as the lack of a nightly rest regime has a detrimental effect on heart health..

The results of the study are reported by the Pharmacy Times resource.

How the studies were conducted "

Scientists conducted a study to evaluate the relationship between sleep patterns and the risk of developing atherosclerosis. The study involved 2,000 patients aged 45 to 84 who did not have cardiovascular disease..

Participants wore a wrist device to track sleep and wake times for 3 years. They measured the total duration of sleep and the time it takes a person to fall asleep..

Participants also completed a weekly sleep diary and took part in one overnight home study, where the exercises measured patients' breathing, sleep phases, awakening after sleep onset, and heart rate..

The scientists also measured arterial plaque in the arteries of the neck, thickness of the carotid complex, and constriction of the peripheral arteries..

What the results show The results show that people with irregular sleep patterns are more likely to develop atherosclerosis, the buildup of plaque on the walls of their arteries.. This disease leads to narrowing of the arteries and blockage of the flow of blood, oxygen and nutrients to the body..

It is also noted that atherosclerosis can lead to the formation of blood clots.. And it increases the risk of a heart attack or stroke..

According to the results of the study, varying sleep duration (more than 2 hours difference per week) increases the likelihood of accumulation of carotid plaques in a person by 12% and increases the likelihood of narrowing of peripheral arteries..

In addition, irregular sleep times that varied by more than an hour and a half per week increased the risks of high calcium levels in the coronary arteries by 1.43 times..

At the same time, doctors have not found a link between irregular sleep times and other cardiovascular diseases..
