Blood Pressure and your body



Blood Pressure and your body

High blood pressure has many harmful effects on the body. It increases the risk of having a heart attack or stroke. By taking control of your blood pressure you can make a positive step towards reducing your overall risk of developing cardiovascular disease. Ireland has one of the highest incidence rates of Stroke and Coronary Artery Disease in Europe, with one in seven of all Irish adults having high blood pressure. High blood pressure can cause silent damage to the blood vessels and the heart. If left untreated the damage may progress and result in a stroke or a heart attack

What is Blood Pressure?

Blood pressure is the force of blood against the walls of the arteries when the heart contracts. Everyone has blood pressure. While a certain amount of pressure is needed to keep the blood flowing, this pressure can increase if the blood meets resistance in the arteries. Blood flowing through the arteries at high pressure can damage artery walls. If this pressure is persistently high, this is called high blood pressure or “hypertension”. High blood pressure is a sign that the heart and blood vessels are being overworked.

How do I know if I have High Blood Pressure?

A consistent blood pressure reading of 140/90 mmHg or higher is considered high blood pressure. You may not know you have high blood pressure, as usually there are no warning signs or symptoms. The only way to know if your blood pressure is high is to have it checked by your GP. Therefore, it is very important to have your blood pressure checked once a year.

Initial assessment:

 • Having your blood pressure measured is quick and easy, and can be done by your doctor or nurse. • Blood pressure is measured using a special instrument called a sphygmomanometer. This involves a cuff being wrapped around your arm just above the elbow, which is then inflated. Automatic blood pressure monitors are commonly used. In these cases, the blood pressure reading appears on a small screen. • Blood pressure is just one of the risk factors for heart disease or stroke, therefore your doctor may decide to do some extra blood and urine tests to identify other risk factors that you may have.

Repeat assessment:

Most doctors will diagnose a person with high blood pressure on the basis of a number of readings. However, sometimes your GP may recommend 24-hour blood pressure monitoring. If so: • This monitor must be worn for 24 hours and will inflate and check your blood pressure every half hour. • Your blood pressure will vary at different times of the day depending on your activity levels, therefore it is important to carry out your normal daily activities while wearing the monitor. • This method of blood pressure monitoring is particularly good for patients who only experience high blood pressure when they visit the doctor’s surgery. This is called “white coat hypertension”. Blood pressure can rise when a person is nervous or anxious.

What causes High Blood Pressure?

• The family history of high blood pressure. • Age (as you grow older, blood pressure tends to rise). • Being overweight. • A high intake of sodium (salt) in the diet. • Physical inactivity. • A high intake of alcohol. • Ethnic Origin: people from African-Caribbean and South Asian communities have a higher predisposition to developing high blood pressure

What should my Blood Pressure be?

If you have Diabetes, Heart Disease, Kidney Disease, or if you have had a Stroke your doctor may prescribe a lower target level. To help you track your blood pressure readings please contact Croí for a copy of the ‘Safe Heart Card’.

Advice for taking your Blood Pressure medications

• Take the medicines exactly as prescribed by your doctor. • Take your medication regularly and at the same time every day. • Make sure you do not run out of tablets. • If you are going on holidays, do not forget to bring your medication. Always carry your medication in your hand luggage just in case your luggage gets lost! For more information on blood pressure medication, please contact Croí for a copy of the ‘Advice for Patients on Heart Medications’ booklet. • Always keep a list of your medication in your wallet. • Do not stop taking your medication without consulting with your doctor first. • If you develop a reaction or an allergy to your medication, contact your doctor immediately.
