High blood pressure means the pressure inside the blood vessels (called arteries) is too high. As the heart pumps against this pressure, it must work harder. Over time, this causes the heart muscle to thicken.

Because there are often no symptoms with high blood pressure, people can have the problem without knowing it. Symptoms most often do not occur until after many years of poor blood pressure control, when damage to the heart has occurred.

Eventually, the muscle may become so thick that it does not get enough oxygen. This can cause angina (chest pain). Without appropriate blood pressure control, the heart muscle can weaken over time and heart failure may develop.

High blood pressure also leads to thickening of the blood vessel walls. When combined with cholesterol deposits in the blood vessels, the risk of heart attack and stroke increases.

Hypertensive heart disease is the leading cause of illness and death from high blood pressure.

Contact your health care provider if you have high blood pressure and develop any symptoms.

Diagnosing high blood pressure early can help prevent heart disease, stroke, eye problems, and chronic kidney disease.

All people age 18 and older should have their blood pressure checked every year. More frequent measurement may be needed for those with a history of high blood pressure readings or those with risk factors for high blood pressure.

Guidelines can change as new information becomes available, Therefore, your provider may recommend more frequent checks based on your blood pressure levels and other health conditions.

If your blood pressure is high, you need to lower it and keep it under control.

• Do not stop or change high blood pressure medicines without talking to your provider.
• Carefully control diabetes and high cholesterol.
