High blood pressure is a common condition in which the long-term force of the blood against your artery walls is high enough that it may eventually cause health problems, such as heart disease.
High blood pressure or hypertension increases the risk of heart disease and stroke. Hypertension risk factors include obesity, drinking too much alcohol, smoking, and family history. Beta-blockers are a common treatment for hypertension.
Beta-blockers (beta-adrenoceptor blocking agents) work mainly by decreasing the activity of the heart by blocking the action of hormones like adrenaline.
Beta-blockers are prescription-only medicines (POMS), which means they can only be prescribed by a GP or another suitably qualified healthcare professional.
Blood pressure ranges include:
- Normal: Less than 120/80
- Prehypertension: 120– 139/80– 89.
- Stage 1 high blood pressure: 140– 159/90– 99.
- Stage 2 hypertension: 160 and above/100 and above.
Hypertension increases the threat of:
- Chronic heart failure:Hypertensive heart disease is the No. 1 cause of death associated with high blood pressure. It refers to a group of disorders that includes heart failure, ischemic heart disease, hypertensive heart disease, and left ventricular hypertrophy (excessive thickening of the heart muscle).
- Memory issues:High blood pressure can also cause blood clots to form in the arteries leading to your brain, blocking blood flow and potentially causing a stroke. Dementia. Dementia is a brain disease resulting in problems with thinking, speaking, reasoning, memory, vision and movement.
- Eye problems:Hypertension can cause damage to the blood vessels in the retina, the area at the back of the eye where images focus. This eye disease is known as hypertensive retinopathy.
- Aneurism:One potential cause is atherosclerosis, which weakens and damages the artery wall. Over time, high blood pressure in a weakened artery can cause a section to enlarge and form a bulge — the aneurysm. Aneurysms can rupture and cause life-threatening internal bleeding.
- First stroke: About three out of four people who have a stroke for the first time have high blood pressure. And an irregular atrial heart rhythm — a condition called atrial fibrillation — is present in about one out of five strokes.
- Metabolic syndrome: Metabolic syndrome is a group of metabolic risk factors that place people at greater likelihood for developing cardiovascular disease and diabetes. About one in three U.S. adults have metabolic syndrome. When a healthcare professional notes these risk factors together, the chances for future cardiovascular problems are greater than any one factor presenting alone.
