Beta-blocker, time-tested drug used to lower heart rate has been shown to have beneficial effects in patients with myocardial Infarction (MI) and heart failure, but a new research indicates that this is always not the case in patients with high blood pressure.

A critical analysis of nine randomized trials, including almost 70,000 hypertensive patients, illustrates that reduction in heart rate due to beta-blockers, increases the risks of all-cause death, cardiovascular death, MI, stroke, and heart failure (p < 0.0001 for all).

Dr. Franz H. Messerli, from Columbia University, said that “pharmacologically induced bradycardia may lead to dyssynchrony between outgoing and reflected pulse wave, thereby increasing central aortic pressure and the hemodynamic burden to the target organs.”

A total of 22 randomized controlled trials were recognized, of which 9 included heart rate data. All told, 34,096 patients received beta-blockers, 30,139 received other antihypertensive drugs, and 3987 received placebo.

After the physical exercise, usage of fish or fish oil capsules is the second most important thing you can do for your health. It’s getting fame as the scientific community discovers more and more of the many extraordinary fish oil benefits.

The various kinds of fish which can be a rich source of fish oil are mackerel, rainbow trout, lake trout, halibut, herring, sardines, oysters, albacore tuna, tuna, turbot, pilchards, anchovies and salmon.

What is Epilepsy ?

Epilepsy is a common term that refers to a tendency to have continuing seizures. The brain sends and receives messages to make action possible. If there is an error to send or receive messages, a concise break in various or all of the brain’s tasks can happen. If this happens a person may have a seizure.

Epilepsy is typified by motiveless, chronic seizures that interrupt the nervous system and can cause mental and physical dysfunction. In the United States, about 2.5 million people are affected by epilepsy and seizures and about 10% of the American population is experienced at least one seizure during their life.

THURSDAY, July 31 (HealthDay News) — Scientists stated that they’ve detected a gene that may reduce the risk of migraines with aura.

Though, the risk is still there, if the person develops migraines with aura, this migraine-protective gene in fact boosts their stroke risk.

“There is a reduced connection of migraine with aura with this gene, but if you have migraine with aura, the risk of stroke is multiplied,” said author, Dr. Tobias Kurth, an assistant professor of medicine at Harvard Medical School.

While, using data from over 25,000 white women who took part in the Women’s Health Study, Tobias and his team came to know that around 18 % of the women have history of migraine.
