For those who have survived a heart attack, mental stress — and not physical stress — may be a stronger predictor of a repeat heart attack or even dying from heart disease, warn researchers.

The team at Emory University investigated whether myocardial ischemia — when blood flow to the heart is reduced such that the heart muscle doesn’t get enough oxygen — induced by mental stress was associated with poor outcomes among heart attack survivors, and how this type of stress testing compares with conventional stress brought on by exercise.


Among more than 300 young and middle-aged individuals enrolled in the study, those who endured myocardial ischemia with mental stress had a two-fold higher likelihood of having another heart attack or dying from heart disease compared with those who did not have cardiac ischemia induced by mental stress.

“In our study, myocardial ischemia provoked by mental stress was a better risk indicator than what we were able to see with conventional stress testing,” said Viola Vaccarino from Emory University’s Rollins School of Public Health in Atlanta and the study’s principal investigator.

This is the only study of its kind in this relatively young adult population of heart attack survivors.

“These data point to the important effect that psychological stress can have on the heart and on the prognosis of patients with heart disease,” she added.

The investigators studied 306 adults aged 61 years or younger (50 years on average and ranging from 22-61 years), who had been in the hospital for a heart attack in the previous eight months.

Traditional stress tests, in which someone exercises on a treadmill or takes a medicine that makes the heart beat faster and harder as if the person was actually exercising, have long been used to check blood flow to the heart and gauge the risk of heart problems.

Taking into account patients’ psychological stress may help clinicians better evaluate the risk of recurrent heart attacks or death seen in some patients surviving a heart attack.

Overall, mental stress induced myocardial ischemia occurred in 16 per cent of patients and conventional ischemia in 35 per cent, suggesting that traditional ischemia due to exercise or drug-induced stress is more common.

Over a three-year follow-up, 10 per cent of patients (28 individuals) had another heart attack and two died of heart-related problems.

The incidence of heart attack or cardiovascular-related death was more than doubled in patients with mental stress induced ischemia compared with those without mental stress ischemia, occurring in 10 (20 per cent) and 20 (8 per cent) patients, respectively.

“Patients who developed ischemia with mental stress had more than two times the risk of having a repeat heart attack or dying from heart disease compared with those who did not develop ischemia during mental stress,” Vaccarino elaborated.

What this means is that the propensity to have a reduction in blood flow to the heart during acute psychological stress poses substantial future risk to these patients,

Such reduction in blood flow, when it occurs in real life, could trigger a heart attack or serious heart rhythm problems, she said.

Another interesting finding, according to Vaccarino, is that ischemia with mental stress and with conventional stress were not strongly related to each other, suggesting that they occur through different pathways.

“This points to the fact that stress provoked by emotions has a distinct mechanism of risk for heart disease and its complications compared with physical stress,” she noted. (IANS)

The Centre on Wednesday directed all Union Ministries and Departments to clear Air India's dues immediately. An office memorandum from the Finance Ministry's Department of Expenditure said: "Recently, the Government of India has decided to disinvest Air India, and the process of disinvestment of Air India and Air India Express is ongoing."

"Air India has stopped extending credit facilities on account of purchase of air tickets. Therefore, all Ministries or Departments are directed to clear Air India's dues immediately." "Air tickets from Air India may be purchased in cash till further instructions."



In 2009, the Centre had mandated that Central government officers travel via Air India for all official purposes including availing of LTC. On Monday, conglomerate Tata Group entered into a share purchase agreement with the Central government for buying out the latter's stake in national carrier Air India, Air India Express, and AISATS.

Sports betting has become increasingly popular among the youth in recent times

Sports betting has been around for centuries for the audience to not only watch the sport but to get more deeply involved in the match. It is a fun and often profitable activity for the viewer to win some extra fortune or simply get some extra sweat while watching the game. At first glance, sports betting may look like it's pure luck, but when you indulge deeper into the activity you realize it is more of a calculative and research activity than just pure luck. We must note that yes, luck does play a certain role to some extend but a win is not completely dependent on luck, if you're putting your bets on a certain team you have to make sure to do some research about the players on the team, history of wins and losses of the team and compare the probability of winning and then place bets.

Even though sports betting has existed since the ancient era, it was not until recently that it became increasingly popular among the youth. This happened due to the legalization of the activity and the rise of online sports betting. The technological revolution has expanded the sports betting industry, offering the bettors new markets and ways to bet. The only major difference between online bookmarkers and traditional brick-and-mortar venues of sports betting is that now you can place bets online from your mobile devices, laptops, computers etc.

The government of Assam has recently consented to translate the research-based book by- Shri Salil Gewali titled "Great Minds on India"

It is indeed good news that the book showcasing the wisdom of India in the eyes of Western intellectuals is getting due recognition and appreciation from other states and abroad. After Karnataka and Punjab, the Government of Assam has recently consented to translate the research-based book by Shillong-based author - Shri Salil Gewali titled "Great Minds on India". The Chief Minister of Assam - Shri Himanta Biswa Sarma was amazed to know that so many top western scientists and philosophers have drawn a considerable amount of inspiration from ancient scriptures of India, particularly in the studies of modern physics, linguistic and astronomy. In the recent meeting with the author, the Chief Minister had highly appreciated Gewali's book and promised to read it thoroughly. Gewali's book was also approved for translation in the year 2020 by the former Chief Minister – Shri Sarbananda Sonowal but due to COVID-19, the translation work was delayed.
