It was more common among the under-60s and women and more people who had NDE's died shortly afterwards. Two years on those who had NDEs were more likely to have lost their fear of death - surely a be...

Choose the correct hypertensive drug

.... And the long-acting calcium channel blockers are linked to a 20 per cent higher risk of heart attack and heart failure in comparison with other drugs. When a new blood pressure drug comes out, it should be compared in a 'head to head' trial with conventional therapy - usually a low-dose diuretic. Hencefor...

Caffeine can induce epilepsy in newborns

A way to calm the heart rhythm

...t six breaths per minute, the respiration rate was linked to a healthier heart rhythm. The findings lead the researchers to speculate whether the practice of the Rosary and yoga mantras may have evolved, in part, as a calming practice, which both opens the mind and benefits the heart and lungs in the long r...

Caution On Use of Cholesterol Drugs

... one version of the pills, which was recalled, was linked to kidney failure. The new guidelines combine the growing realization that elevated cholesterol early in life can cause deadly cardiovascular consequences later, and convincing evidence that statin drugs are highly effective at controlling runaway ...

Vitamin E useful for Alzheimer's
