Hypertension FAQs

What is hypertensioni,ii?

You are said to have high blood pressure (medically known as hypertension) if readings on separate occasions consistently show your blood pressure to be 140/90mmHg or higher.

There are three different kinds of hypertension:

  • Arterial hypertension
  • Pulmonary hypertension
  • Portal hypertension

A blood pressure reading below 130/80mmHg is considered to be normal.

In general, the term ‘hypertension’ is used to refer to essential arterial hypertension, typically defined as blood pressure above 140/90 mmHg.

What causes hypertensioniii?

For more than 90 percent of people with high blood pressure, the cause is unknown – this is called primary or essential hypertension. However, your chances of having high blood pressure increase as you get older. Even though there is often no clear cause of high blood pressure you may have an increased risk if you:

  • are overweight
  • have a relative with high blood pressure
  • smoke
  • are of African or Caribbean descent
  • eat too much salt
  • don’t eat enough fruit and vegetables
  • don’t do enough exercise
  • drink too much coffee (or other caffeine-based drinks)
  • drink too much alcohol
  • are aged over 65

In the remaining 10 percent, there is an underlying cause – this is called secondary hypertension. The main causes for secondary hypertension are:

  • chronic kidney disease
  • diseases in the arteries supplying the kidneys
  • chronic alcohol abuse
  • hormonal disturbances
  • endocrine tumours

 

What are the symptoms of hypertensionv,vi?

High blood pressure usually does not cause any symptoms. This means that it may go unnoticed until it causes secondary organ damage, such as a stroke or heart attack.
However, severe hypertension can cause symptoms such as:

  • headache
  • sleepiness
  • confusion
  • coma

 

Can hypertension be preventedv,vi?

An unhealthy diet is estimated to be related to about half of hypertension (About 30% related to increased salt consumption, and about 20% related to low dietary potassium (low fruit and vegetables). Physical inactivity is related to about 20% of hypertension and obesity is related to about 30% of hypertension. Excess alcohol and fat consumption also causes hypertension. Being tobacco free is especially important for people with hypertension.

  • Lifestyle changes can be made to help prevent high blood pressure by:
  • losing weight if you need to
  • reducing the amount of salt you eat
  • exercising regularly
  • eating a healthy diet
  • cutting back if you drink too much alcohol
  • stopping smoking
  • cutting down on caffeine

 

Why and how is hypertension treatedvii?

Just a 2 mmHg drop in systolic blood pressure in middle aged patients can:

  • Reduce the risk of death due to ischaemic heart disease and other cardiovascular causes by 7 per cent
  • Reduce the risk of stroke mortality by 10 per cent

Medical treatment pathways include:

  • Alpha-blockers
  • Angiotensin-II-converting enzyme inhibitors (ACEIs)
  • Angiotensin-II receptor blockers (ARBs)
  • Beta-blockers
  • Calcium channel blockers
  • Diuretics

 

Is there a benefit to hypertensive patients having an exercise programmeviii?

The prevention and treatment of hypertension are a high priority in medicine and public health. It is well documented that blood pressure reduction with medication significantly reduces cardiovascular risk. Exercise remains a cornerstone therapy for the primary prevention, treatment, and control of hypertension.

 

How can health behaviour modification be effective in helping manage hypertensionix?

Blood pressure and other cardiovascular risk factors can be improved by following a healthy diet, engaging in regular physical activity, moderating alcohol consumption, reducing dietary sodium, avoiding tobacco exposure and managing high stress levels. Brief, individualized health care professional interventions increase the probability of lifestyle change.

Ongoing investigation around lifestyle interventions proven to be beneficial in the prevention and treatment of hypertension resulted in updated guidelines from the European Society of Hypertension (ESH) and of the European Society of Cardiology (ESC) advise thatx:

  • Epidemiological studies suggested that regular aerobic physical activity may be beneficial for both prevention and treatment of hypertension and to lower CV risk and mortality
  • Hypertensive patients should be advised to participate in at least 30 min of moderate-intensity dynamic aerobic exercise on 5–7 days per week

 

What are the risks associated with uncontrolled hypertensionxi?

If left uncontrolled, hypertension may lead to serious cardiovascular health complications such as heart attack or stroke. Patients with a history of hypertension have at least six times greater risk of heart failure than those who do not have such a history.

 

Does this contribute to healthcare spending across Europexii?

Uncontrolled hypertension is therefore a significant contributor to healthcare spending across Europe, as overall cardiovascular disease is estimated to cost the EU economy €196 billion a year.3 Better control of hypertension is imperative not only from a patient and public health perspective, but also to reduce the overall financial burden of cardiovascular disease.

 

Does this dance programme support compliance in the treatment of hypertension?

Supporting programmes for healthcare professionals and patients can play an important role, by providing education on hypertension and the motivational skills for lifestyle changes.
