60% of the people who suffer from a sudden cardiac arrest die even before reaching the hospital
Among the age group of 25-50,less than two percent of the 100,000 surveyed agreed that they knew CPR
The number was about 95% in the metropolitan cities where people are supposedly proactive about their health
Sept 29, 2016: Around 98 per cent Indians are not trained in basic life-saving technique of cardiopulmonary resuscitation (CPR) during sudden cardiac arrest, shows a survey conducted by Lybrate, an online doctor consultation platform.
In India, sudden cardiac arrest (SCA) is a major cause of death due to cardiovascular diseases (CVD), and shockingly 60 per cent of the people who suffer an SCA succumb to it even before they reach hospital.

The survey conducted in 20 Indian cities among the age group of 25-50 showed that less than two per cent of the 100,000 surveyed agreed to knowing the technique, while only 0.1 per cent said they have performed it at least once on someone in case of an emergency.
Even though people in metropolitan and Tier 1 cities are more proactive about their health, the knowledge of CPR is dismal even among them, with 95 per cent of the people claiming to have no knowledge about administration of the procedure.

“Indians are predisposed to heart conditions and even though cardiac-related conditions are taking a huge toll on human lives in the country, it is very sad that people are not aware about CPR or are trained to perform it,” said Saurabh Arora, founder and CEO of Lybrate, in a statement. (IANS)
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)
