Correlation between Insomnia with Heart Attack Risk

Insomnia is a bad habit that often interfere with an adult. This is a warning to those who often have difficulty sleeping or frequent awakening from sleep at night. Recent studies experts at the Norwegian state, those who have trouble sleeping well at night greater risk of experiencing a heart attack. The relationship between insomnia and increased heart attack risk is not yet clear. But certainly, sleep disorders have an impact on blood pressure and inflammation, both of which are risk factors for heart attack.

Correlation between Insomnia with Heart Attack Risk
"When insomnia symptoms become so common and easy to treat, it is important for people wary of the relationship of insomnia and heart attacks, and then consult with a physician if you have a sleep disorder," said Dr.. Lars Erik Laugsand, internists from the Norwegian University of Science and Technology in Trondheim.

Laugsand confirmed, the findings are published in the October 24 issue of the journal Circulation is merely evidence of an association and not causality. Future research needs to be done to uncover more about the mechanisms behind this relationship. In his research, analyze health data Laugsand sleep about 53,000 male and female survey participants between 1995-97. 2400 also revealed that respondents had a heart attack 11 years later lapse.

Researchers found that those who sleep difficulties almost every day had 45 percent increased risk of heart attack, compared with respondents who never troubled to sleep soundly. In addition, those who do not sleep soundly or lie awake at night is also 30 percent higher risk than those who sleep soundly. While those who feel that their body is not fresh / fit after a night's sleep had an increased risk of heart attack by 27 percent than that feel fit.

In this study, researchers took into account various factors such as age, gender, sex, marital status, educational level, blood pressure, cholesterol levels, diabetes, weight loss, exercise, shift work patterns. Symptoms of depression and anxiety as a trigger for insomnia also were taken into account.

Dr. Gregg Fonarow, professor of cardiology at the University of California, Los Angeles, as well as spokesman for the American Heart Association (AHA), said a number of previous studies have revealed that sleep disturbance is associated with the risk of heart attack.

"Previous studies reveal mixed results, but have not been able to uncover why healthy sleep makes the heart healthy," said Fonarow. While Dr. Edward A. Fisher, professor of cardiovascular medicine at NYU Langone Medical Center in New York City, said one possible explanation of this finding is the change in the body's metabolic processes. In the body, metabolism regulated by a circadian rhythm which of course varies greatly among the individual sleep cycles. "It is known that animals will be disturbed rhythm sirkadiannya metabolic changes. If this occurs in humans, it will increase the risk of heart disease," said Fisher.
