Regular exercise may help people with heart disease in family

NEW YORK — Regular daily exercise may not only rev up your fitness levels, but it may also significantly cut down risk of heart diseases that could be running in your family, according to the researchers.

Greater grip strength, more physical activity and better cardiorespiratory fitness are associated with reduced risk for heart attacks and stroke — even among people with a genetic pre-disposition for heart disease, researcher said in the the findings published in the American Heart Association’s journal Circulation.

The researchers, for the study, looked at data from roughly a half-million people in the UK Biobank database. For participants with an intermediate genetic risk for cardiovascular diseases, it was revealed that those with the strongest grips were 36 per cent less likely to develop coronary heart disease and had a 46 per cent reduction in their risk for atrial fibrillation, compared to study participants with the same genetic risk who had the weakest grips.

“The main message is that being physically active is associated with a lower risk of heart disease, even if you have a high genetic risk,” said Erik Ingelsson, lead study author and Professor of Medicine at Stanford University’s School of Medicine in California.

To reach this conclusion, researchers looked at data from roughly a half-million people in the UK Biobank database.

“The main message is that being physically active is associated with a lower risk of heart disease, even if you have a high genetic risk,” said Erik Ingelsson, lead study author and Professor of Medicine at Stanford University’s School of Medicine in California.

Among individuals deemed at high genetic risk for cardiovascular diseases, high levels of cardiorespiratory fitness were associated with a 49 per cent lower risk for coronary heart disease and a 60 per cent lower risk for atrial fibrillation compared to study participants with low cardiorespiratory fitness.

“The study is not a prescription for a specific type or amount of exercise and because the results come from an observational study, Ingelsson said, adding that “we can’t definitely claim a causal connection.”

Nonetheless, the researchers said the data is robust and the results are worthy for consideration in guidelines.

Drinking 3 cups of coffee or tea daily may keep stroke risk at bay

KATHMANDU — There have been several conflicting studies on the health benefits of drinking coffee and tea and their various varieties. But drinking up to three cups of coffee or tea in a day is safe because it reduces irregular heartbeat and stroke risk, according to a new study published in the journal JACC: Clinical Electrophysiology.

Coffee has previously been believed to worsen abnormal heart rhythms, as doctors generally discourage patients suffering from the condition. However, the results of this particular study say that a daily consumption of upto 300 mg of caffeine may be safe for arrhythmic patients.

This is because the caffeine acts as a stimulant to the central nervous system and blocks the effect of adenosine. Adenosine is a chemical which causes Atrial Fibrillation (AFib).

A single cup of coffee contains about 95 mg of caffeine. It acts as a stimulant to the central nervous system and works to block the effects of adenosine — a chemical that causes AFib.

AFib is the most common heart rhythm disorder, causes the heart to beat rapidly and skip beats, and if left untreated, can cause strokes.

“There is a public perception, often based on anecdotal experience, that caffeine is a common acute trigger for heart rhythm problems,” said lead author Peter Kistler, Director at Melbourne’s Alfred Hospital.

But, “caffeinated beverages such as coffee and tea have long-term anti-arrhythmic properties mediated by antioxidant effects and antagonism of adenosine,” he added.

A meta-analysis of 228,465 participants showed that AFib frequency decreasing by 6 per cent in regular coffee drinkers, and an analysis of 115,993 patients showed a 13 per cent reduced risk.

Another study of 103 post-heart attack patients who received an average of 353 mg of caffeine a day showed improvement in heart rate and no significant arrhythmias — or abnormal heart rhythms, that cause the heart to beat too fast, slow or unevenly.

However, in two studies, where patients drank at least 10 cups and nine cups of coffee per day, showed an increased risk for ventricular arrhythmias (VAs) – a condition in which the lower chambers of the heart (ventricles) beat very quickly.

On the other hand, patients with pre-existing heart conditions who consumed two or more energy drinks — that contains concentrated caffeine — per day reported palpitations within 24 hours.
