Here Comes The Novel Method to Predict Fatal Heart Disease

Furthermore, the technology does not require any radiation exposure, which is essential in nuclear stress tests

A novel method called stress cardiac MRI can not only diagnose heart disease, but can also predict which cases are potentially fatal, suggests a new research.

The study showed that predicting mortality is a key requirement for the technology to be more widely used.

In addition, results suggest cardiac magnetic resonance (CMR) has the potential to be a non-invasive, non-toxic alternative to stress echocardiograms, catheterisations and stress nuclear exams in identifying the severity of the coronary artery disease.

“We’ve known for some time that CMR is effective at diagnosing coronary artery disease, but it’s still not commonly used and represents less than one per cent of stress tests used in this country,” said senior author Robert Judd, co-director of the Duke Cardiovascular Magnetic Resonance Center in the US.

For the study, researchers analysed data from more than 9,000 patients who underwent CMR.

The findings, published in JAMA Cardiology, showed that for patients without any history of heart disease and at low-risk based on traditional clinical criteria, those with an abnormal CMR scan were 3.4 times more likely to die compared to patients with a normal CMR scan.

For the entire patient population, there was a strong association between an abnormal stress CMR and mortality, even after adjusting for patient age, sex and cardiac risk factors, the team found.

While non-invasive cardiac stress testing is a cornerstone in the clinical management of patients with known or suspected coronary artery disease, CMR works as well or better than other exams at identifying heart wall motion, cell death and the presence of low blood flow, said the study.

“With the findings from this study suggesting that stress CMR is effective in predicting mortality, we provide a strong basis for a head-to-head study between stress CMR and other modalities,” Judd noted. (IANS)

Doctor Says, Smiling Can Improve Heart Health and Well-Being

Exercise and diet are keys to a healthier life, as many studies show, but here's something that may surprise you: A heart specialist also recommends smiling to improve your health.

Exercise and diet are keys to a healthier life, as many studies show, but a heart specialist also recommends something more.

“One, two, three — twirl.”

Kendra Martin is taking photographs of three little girls in chiffon dresses. As they twirl, Martin tells them to smile.

“All right, big smiles!”

“I tell people to fake laugh, and they feel stupid doing it, but the result is theyʼre laughing, and it turns into a genuine smile,” Martin said.

And, in this case a giggle.

Big grins and giggles pay off on camera. The girls may be too young to have heart problems, but the smiles can promote heart health.

Brain rewiring

Dr. Anand Chockalingam is a heart specialist at the University of Missouri Health Care who tells his patients to smile.

“When we smile, the brain wiring gets altered. The chemicals that are released are more positive,” he said.

Chockalingam’s advice is supported by a number of studies. He says smiling is a first step in fighting stress and its ill health effects.

When you feel stressed, your body releases a surge of hormones, including adrenaline and cortisol.

Adrenaline increases your heart rate and blood pressure. Cortisol, the primary stress hormone, increases sugars in the bloodstream. If you are truly in danger, these hormones can help, but too much of these stress hormones too frequently can lead to heart disease and stroke.

Bad habits arise

People who are stressed look for ways to cope. The American Heart Association says smoking, overeating or drinking alcohol as a way to reduce the stress can harm your heart and other organs.

“Once people smile, they are relaxing,” Chockalingam said. “This relaxation directly lowers blood pressure, improves sugar levels in the blood.”

Chockalingam tells his patients to smile 20 times an hour. It might seem like a lot, but it doesn’t involve drugs or have any negative side effects.

“If we are smiling, we are breaking that link between stress and health,” he said.

“Waking up in the morning with a smile on my face, you know, itʼs gonna put everybody in a better mood,” she said.

And it provides a little boost to everyone’s heart health. (VOA)
