Don't just plod 'if you want a long, healthy life'

New Study says intense workouts for shorter periods daily are better for the heart and could add extra five years to someone's life.

Want a long and healthy life? Don't just plod, but go for short stints of intense exercise daily, says a new study.
Researchers in Denmark have found that intense workouts for shorter periods daily are better for the heart and could add up to an extra five years to someone's life, the latest edition of the 'Hypertension' journal reported.
The Danish study by Bispebjerg University Hospital adds to evidence that moderate exertion, while clearly beneficial, might not be all that is needed to give the best level of protection against cardio vascular disease.
The researchers who monitored the health of 5,000 Danish people in Copenhagen, who cycled regularly for 20 years, found that most benefit was gained from pedalling intensively for short periods.
Men who said they rode fast could expect to live 5.3 years longer than those who said they rode slowly, while for such women the figure was 3.9 years, the findings revealed.

HEALTH & FOOD: Is chocolate good for your heart? It depends!

Chocolate may be good for the heart but cardiologists are not giving you a licence to indulge.

New research presented at Europe's biggest medical meeting on Monday suggested chocolate consumption might be associated with a one third reduction in the risk of developing heart disease.

Just why there should be such a link was unclear, the European Society of Cardiology congress was told.

There has been a string of scientific studies in recent years showing a potential health benefit from eating chocolate. Dark chocolate, in particular, contains compounds called flavanols thought to be good for the blood system.

In an attempt to paint a clearer picture, Oscar Franco and colleagues from the University of Cambridge pooled results from seven studies involving 100,000 people.

Five of the studies showed a beneficial link between eating chocolate and cardiovascular health, while two did not.

Overall, the findings showed the highest levels of chocolate consumption were associated with a 37 percent reduction in cardiovascular disease and a 29 percent reduction in stroke compared with the lowest levels.

HEALTH RESEARCH: Limiting salt intake checks blood pressure, protects heart!


For LEED Consultancy / IGBC Certifications, Green Building Design, Green Homes, Green Factory Buildings, Green SEZs, Green Townships & Energy Audits - www.greentekindika.com

IANS / The Hindu /  NEW DELHI, August 13, 2011.

Several global studies have clearly indicated that reduction in salt intakes even by small quantities significantly decreases the average blood pressure of a population.
Several global studies have clearly indicated that reduction in salt intakes even by small quantities significantly decreases the average blood pressure of a population - The Hindu.


A frantic lifestyle, long working hours and even longer distances to commute in metros and cities make ready—to—eat packaged food an attractive option, which requires only a few minutes of warming.
But the flip side is that their salt content is on the higher side. So regular dependence on fast food or packaged foods promotes greater salt intake, which accumulates in the body and poses serious health risks.
These risks are rising blood pressure (BP) levels, which could act as trigger for cardiovascular diseases like heart attacks, besides cerebral strokes, as well as kidney failure, B. Sesikeran, director of Hyderabad—based National Institute of Nutrition (NIN), told the IANS.
“Several global studies have clearly indicated that reduction in salt intakes even by small quantities significantly decreases the average blood pressure of a population. The prevalence of hypertension is low among populations consuming less than three grams of salt daily. The usual increase in BP with age is also not seen with such (low) intakes,” Sesikeran said.
Last week, the NIN recommended a reduction of salt content by the packaged food industry, besides limiting maximum salt intake to six grams per day, down from the eight grams permitted under 1998 nutritional guidelines.
“The prevalence of high blood pressure in more than a third of urban Indian population could be largely contributed by higher salt intakes, though several other factors, including stress and other chronic disease, may also be involved,” said Sesikeran.
However, salt, for all its negative publicity, is crucial for the functioning of the heart, adrenals, liver and kidneys, and even for digesting food. It transports nutrients to the cells, keeps calcium and other minerals soluble and maintains the body{gt}s balance of fluids.
Sea or raw salt seems to be a healthier option because it has a number of trace minerals like potassium, magnesium and calcium, but processed salt loses all these micro—nutrients.
A study by Patricio E. Ray, published in the journal Kidney International, has found that potassium deficiencies increase BP and induce salt sensitivity, that is bringing on more adverse effects with the same quantity of salt.
“Potassium has the exact opposite effect on the BP when compared with sodium in the edible salt. Its higher intake also results in more expulsion of sodium from the kidneys,” said Sesikeran.
Simply stated, posassium in diet is effective in lowering BP.

Riaz Mohammad
Riaz Mohammad.

In a touching story of communal harmony that only movies are made of, the heart of a brain dead Hindu donor from Tiruvannamalai was transplanted to a dying Pakistani Muslim, by a Christian cardiac surgeon at a Chennai hospital.
The recipient, 54-year-old Riaz Mohammad was a lucky man for he waited only 17 days before he received a young, healthy heart that did not match any Indian on the waiting list for heart transplants.
The ailing Pakistani national was on his last legs when he came to Chennai — he had already undergone an angioplasty and two cardiac bypass surgeries at Dubai, where he runs a successful business.
“The only option left for Mr Mohammad was a heart transplant. He registered under the Tamil Nadu Network for Organ sharing on June 23, and moved into the hospital guesthouse with his family to wait for a heart,” said Dr K.M. Cherien, veteran cardiac surgeon and chairman of Frontier Lifeline Hospital.
On July 8, a 36-year-old man from Tiruvannamalai met with an accident, and was declared brain dead at Global Hospitals here.

IANS / The Hindu /  WASHINGTON, July 10, 2011.

Researchers have changed a star-shaped brain cell and a skin cell into a heart cell — offering the possibility of cell-based therapy for cardiovascular diseases.
Heart cells are one of the most sought-after cells in regenerative medicine because they could potentially repair injured hearts by replacing lost tissue.
Researchers of University of Pennsylvania School of Medicine showed the direct conversion of a non-heart cell type into a heart cell by RNA transfer.
The signature of a cell is defined by molecules called messenger RNAs (mRNAs) — the chemical blueprint for making a protein.
Investigators changed an astrocyte (a star-shaped brain cell) and a fibroblast (a skin cell) into a heart cell, using mRNAs, reports the journal Proceedings of the National Academy of Sciences.

HEALTH ALERT: Painkillers 'linked to irregular heart rhythm'!

Have you read, “Mayhem of the Miserables!” available @ US$ 1/- with the Smashwords Summer/Winter promotion, ending July 31, 2011



Painkillers 'linked to irregular heart rhythm'

Commonly used painkillers like ibuprofen and aspirin can increase the risk of developing an irregular heart rhythm by up to 40 per cent, according to a new study published in the British Medical Journal.
The anti-inflammatories have been previously linked to a higher chance of heart attacks and strokes. Now, researchers at Aarhus University Hospital in Denmark have shown for the first time a connection between the drugs and atrial fibrillation, also known as irregular heart rhythm or flutter.
The condition is more common than heart failure and stroke, and is linked to a higher long-term risk of developing both, say the researchers.
Confirming the results, Prof Henrik Toft Sørensen, who led the study, however, said that heart disease patients should not stop taking the drugs, but they should discuss the potential risks with their doctor.
"The absolute risk is still low. It increases your risk from a very low level to a higher, but still low level," he was quoted by 'The Daily Telegraph' as saying.

HEALTH, HEART: No need for a bypass!

Have you read, “Mayhem of the Miserables!” available @ http://www.smashwords.com/books/view/52075

DR. SANJIV AGRAWAL / The Hindu / July 2, 2011.

Heart
Human Heart.

Angioplasty has become as safe and long lasting as a bypass for patients with multiple blocks in the heart.
Sagar (43) was a social drinker, non-smoker, maintained ideal weight and followed a vegetarian diet. Three years ago he was suddenly struck down by a heart attack; an eerily familiar tale in India.


Heart disease is one of India's biggest public-health threats. The steep increase in heart attacks among Indians below 45 years is of grave concern. In particular, the occurrence of lesions or blockage in the heart vessels due to deposits of fat, cholesterol, platelets, and calcium has become a common cardiac ailment. It impedes blood flow and if left untreated could result in myocardial infarction (heart attack). This condition, also known as Coronary Artery Disease (CAD), is the leading cause of death in the world. Symptoms could range from chest pain, palpitation or dizziness to none at all. Several causes could lead to these heart blocks including being overweight, smoking, hypertension, diabetes, physical exertion and stress.

HEALTH, Heart wellness: When it's out of rhythm

Have you read, “Mayhem of the Miserables!” available @ http://www.smashwords.com/books/view/52075

 DR. VANITA ARORA / The Hindu.


Does your heart seem to go too fast or skip an occasional beat? Learn what the problem could be.
What is an arrhythmia?
An arrhythmia is a change in the regular beat of the heart. The heart may seem to skip a beat or beat irregularly. It may beat very fast or very slowly. So it's basically all about the heart beat.
Are arrhythmias serious?
In some patients with serious symptoms, arrhythmias themselves are dangerous. It requires medical treatment to keep the heartbeat regular.
Some patients have a very slow heartbeat (bradycardia), causing them to feel lightheaded or lose consciousness. If left untreated, the heart may stop beating and cause death.
In others, who have a very fast heart beat, this may cause loss of consciousness due to drop in blood pressure. If untreated within six minutes it can cause sudden cardiac arrest.
