Mental stress may cause reduced blood flow in hearts of young women with heart disease

Younger women with coronary heart disease and mental stress are more susceptible to myocardial ischemia (reduced blood flow to the heart muscle, which can lead to a heart attack), compared to men and older patients, according to new research in Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association.

Coronary heart disease is a leading cause of death in American men and women, but studies show that younger women have higher rates of complications and death after a heart attack compared to their male counterparts.

“Younger women tend to have quite a lot of stress in their lives. Many of them have full-time jobs and at the same time have numerous responsibilities at home; financial hardship, as well as depression and anxiety which are common in this group,” said Viola Vaccarino, M.D., Ph.D., lead study author, professor and chair of the department of epidemiology at Emory University in Atlanta, Georgia. “Clinicians should ask about stress and emotional difficulties in these patients and recommend ways to help, such as finding time to relax and exercise.”

Lipid testing underutilized in adults taking antipsychotic medications

Too few adults taking antipsychotic medications are being screened for abnormalities in lipids, which include cholesterol and triglycerides, new research from the University of Colorado Anschutz Medical Campus finds.

The biggest gap in screening is among adults age 40 and younger, the group for whom early detection and intervention has been shown to be effective when additional cardiovascular risk is present.

Adults with serious mental illness die 20 to 30 years earlier than their peers, largely due to increased risk for diabetes, high cholesterol, high blood pressure and heart disease. Taking antipsychotic medication increases that risk. The American Diabetes Association and American Psychiatric Association recommends more intensive diabetes and cholesterol lipid screening for patients receiving antipsychotics, but rates of screening have remained low.

Let it go: Reaction to stress more important than its frequency

How you perceive and react to stressful events is more important to your health than how frequently you encounter stress, according to health researchers from Penn State and Columbia University.

It is known that stress and negative emotions can increase the risk of heart disease, but the reasons why are not well understood. One potential pathway linking 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.

Nancy L. Sin and colleagues wanted to find out if daily stress and heart rate variability — a measure of autonomic regulation of the heart — are linked. Heart rate variability is the variation in intervals between consecutive heartbeats.

Back to school and back to sleep

Sleep matters for kids, especially when they are stressed. A new study led by researchers Jinshia Ly, Jennifer J. McGrath and Jean-Philippe Gouin from Concordia University’s Centre for Clinical Research in Health and the PERFORM Centre shows that poor sleep might explain how stress impacts health in kids.

A good night’s sleep

Getting a good night’s sleep might buffer the impact of stress on kids’ cortisol level, which is a hormone produced in the adrenal gland to regulate the body’s cardiovascular, metabolic and immune systems. While short-term exposure to cortisol prepares the body for the “fight or flight” response, long-term exposure to cortisol can put people at risk for health problems, like heart diseases, weight gain and depression.

Almost three-quarters of patients with no coronary heart disease have persistent symptoms

Around one in five patients with chest pain will have no obvious signs of coronary artery disease after investigation, and their symptoms are unlikely to have a physical cause.

But it is not always clear who these patients are, and they often undergo extensive and expensive tests to find out that nothing is wrong with their hearts.

The German authors therefore wanted to test the prevalence of physical and mental symptoms in 253 patients who had been investigated for chest pain/shortness of breath/palpitations and found to have no coronary artery disease.
