New vaccine for High blood pressure

The blood pressure injection you need just twice a year

Jab blocks effects of a hormone in body that triggers high blood pressure

So far been tested only on rats, and successfully lowered high readings

A vaccine given just twice a year could keep high blood pressure at bay. The jab could free millions of people from the burden of taking pills every day to keep their condition under control.

It works by blocking the effects of a hormone in the body that triggers high blood pressure by making the muscles surrounding blood vessels contract.

This chemical, called angiotensin 2, forces muscles to keep contracting, which makes blood vessels narrower and increases the pressure on vessel walls – raising the risk of a heart attack or stroke. The vaccine prompts the immune system to release antibodies that stop angiotensin 2 from reaching the muscles.

The experimental jab, which has so far been tested only on rats, successfully lowered their high readings and kept blood pressure at lower, safer levels for at least six months before a booster was needed.

Researchers at Osaka University in Japan, where the jab is being developed, hope to carry out trials on humans within the next two years. High blood pressure, or hypertension, affects one in five adults in the UK and is thought to be responsible for half of all heart attacks and strokes.

It develops when blood vessel walls lose their ability to stretch and dilate, restricting the flow of blood through the body.

In some patients, it’s possible to get readings down by eating less salt and taking more exercise, but millions need pills to control it.

One of the main treatments is a class of drugs known as angiotensin  2 receptor blockers (ARBs).

These work by stopping angiotensin 2 from locking on to receptors on the outside of muscle cell walls and thereby triggering the dangerous contractions that cause high blood pressure.

Heart

Your heart takes care of you, but are you taking care of your heart? Some things about your heart can’t change- like your family history- but there’s still a lot you can do to keep your heart healthy.  Getting active, losing weight, eating green and colorful vegetables and fruits, quitting smoking and reducing stress are all ways of being good to your heart. Add garlic, ginger, and fiber to your diet by eating legumes (kidney beans, black beans,  lentils may help lowering cholesterol, fight the buildup of cardiovascular plaque and lower the blood pressure.

Protect Your Heart

High blood pressure affects one in every four South Asians (India, Pakistan, Bangladesh, SriLanka), and the number one risk factor for stroke and a major risk factor for heart disease. Yet 42% of people with high blood pressure don’t know they have it, because it produces no symptoms.
