Too little sleep can cause dangerous heart problems.


       Adults who sleep too little or too much may increase their risk of heart attack or stroke, researchers say.

In a nationally representative study of adults in the United States, those who slept seven hours a night had the lowest risk of cardiovascular disease, calculated as 3.7 years of aging beyond their age. Besides, it’s with 4.5 years for those who sleep six or eight hours and 5.1 years for those who sleep five hours or less per night.

“Insufficient sleep duration has negative effects on many parts of the body including the cardiovascular system,” said study lead author Quanhe Yang, senior scientist in the Epidemiology and Surveillance Branch. closely, the Heart Disease Department said.

Cardiac age is defined as the predicted age of a person’s vascular system based on their cardiovascular risk profile and was introduced by the Framingham Heart Study in 2008, Yang noted.
For example, if a 40-year-old man has a heart age of 44 years based on his cardiovascular risk profile – individual risk of heart disease – then his excess heart age is 4 years. This means that in reality, this person’s heart is four years older than its actual age. The concept of heart age simplifies the definition of risk.

The Centers for Disease Control and Prevention’s (CDC) goal with this study was to find ways to effectively communicate the impact of insufficient sleep on heart health, Yang noted.

Yang and colleagues analyzed data from the 2007-2014 National Health and Nutrition Examination Surveys on 12,755 participants between the ages of 30 and 74 with no history of heart disease or stroke. .

Based on self-reported mean nighttime sleep, the team divided people into five groups. About 13 percent on average sleep five hours or less per night, 24 percent sleep six hours, 31 percent sleep seven hours, 26 percent sleep eight hours, and the remaining 5% sleep nine hours or more each night.

The researchers calculated the participants’ excess heart age by including age, sex, blood pressure, whether they were being treated for hypertension, smoking history, diabetes and cholesterol to come up with an estimate. overall cardiovascular risk profile. They then aggregated that risk profile into cardiac overage years, reported July 30 in the journal Sleep Health.

This could motivate more people, especially young people, among whom are at increased risk of cardiovascular disease, to be aware of the importance of getting seven hours of sleep a night.

Shorter sleep duration may contribute to cardiovascular risk through effects on metabolic and endocrine functions, inflammation, vascular damage, along with circadian bias, Fonarow added. There are “heart age” calculators available online, he notes, including one on the New York City health department website (here:
