New Delhi:Sudden Cardiac Arrest (SCA) claims over three lakh lives every year, including those of 7,000 children, health experts said here on Saturday.

They stated that SCA takes one life every two minutes, claiming more lives than breast cancer, lung cancer, or AIDS. Over 60 percent of the people are still unaware of the disease.

“Ventricular fibrillation is the most common cause of cardiac arrest. Not every heart attack is a cardiac arrest,” said Vanita Arora, associate director and head of cardiac electrophysiology lab and arrhythmia services at Max Super Specialty hospital.

She said that during SCA the heart stops beating, no blood is pumped to the rest of the body and the heart needs to be revived through electric shock.

“Our aim is to educate people about the urgent need to recognise the difference between the two and the immediate measures needed to address it. If maximum Indians can be trained to carry out cardiopulmonary resuscitation (CPR), many lives can be saved every day,” said Arora speaking at a panel discussion on Sudden Cardio Arrest and its Prevention.

Sumeet Sethi, a leading interventional cardiologist, said a heart attack affects the “plumbing” of the heart, caused by a blockage in a blood vessel that interrupts the flow of blood causing a part of the heart muscle to die.

“The heart must be “unclogged” with drug therapy, angioplasty or surgery in order to continue the blood flow to the rest of the body,” Sethi said.

“Cardiac arrest is reversible in most victims if treated within minutes. It can be reversed if a trained emergency rescue team reaches the person quickly. Chances of survival reduce by 7-10 percent with every passing minute.” he said

Good news for tea lovers! Researchers have found that drinking tea at least three times a week is linked with a longer and healthier life.

“Habitual tea consumption is associated with lower risks of cardiovascular disease and all-cause death,” said study first author Xinyan Wang, Chinese Academy of Medical Sciences, Beijing in China.

“The favourable health effects are the most robust for green tea and for long-term habitual tea drinkers,” Wang added.

The analysis, published in the European Journal of Preventive Cardiology, included 1,00,902 participants of the China-PAR project2 with no history of heart attack, stroke, or cancer.

Participants were classified into two groups: habitual tea drinkers (three or more times a week) and never or non-habitual tea drinkers (less than three times a week) and followed-up for a median of 7.3 years.

Habitual tea consumption was associated with more healthy years of life and longer life expectancy.

For example, the analyses estimated that 50-year-old habitual tea drinkers would develop coronary heart disease and stroke 1.41 years later and live 1.26 years longer than those who never or seldom drank tea.

Compared with never or non-habitual tea drinkers, habitual tea consumers had a 20 per cent lower risk of incident heart disease and stroke, 22 per cent lower risk of fatal heart disease and stroke, and 15 per cent decreased risk of all-cause death.

The potential influence of changes in tea drinking behaviour were analysed in a subset of 14,081 participants with assessments at two time points.

The average duration between the two surveys was 8.2 years, and the median follow-up after the second survey was 5.3 years.

Habitual tea drinkers who maintained their habit in both surveys had a 39 per cent lower risk of incident heart disease and stroke, 56 per cent lower risk of fatal heart disease and stroke, and 29 per cent decreased risk of all-cause death compared to consistent never or non-habitual tea drinkers.

“The protective effects of tea were most pronounced among the consistent habitual tea drinking group. Mechanism studies have suggested that the main bioactive compounds in tea, namely polyphenols, are not stored in the body long-term,” said study senior author Dongfeng Gu.

“Thus, frequent tea intake over an extended period may be necessary for the cardioprotective effect,” Gu added.

In a sub-analysis by type of tea, drinking green tea was linked with approximately 25 per cent lower risks for incident heart disease and stroke, fatal heart disease and stroke, and all-cause death.

However, no significant associations were observed for black tea, the study said.

According to the researchers, two factors may be at play. First, green tea is a rich source of polyphenols which protect against cardiovascular disease and its risk factors, including high blood pressure and dyslipidaemia.

Black tea is fully fermented and during this process polyphenols are oxidised into pigments and may lose their antioxidant effects.

Second, black tea is often served with milk, which previous research has shown may counteract the favourable health effects of tea on vascular function, the study said. (IANS)
