The Basics of Blood Pressure

What is blood pressure?

Simply put, blood pressure is a measurement of the force exerted on the arteries when the heart pumps blood through your body. Results are expressed in millimeters of mercury (mmHg), and written as a fraction with systolic over diastolic pressure. Normal blood pressure is about 120/80. Systolic blood pressure indicates the force applied when the heart pumps, while diastolic blood pressure is the force when the heart is at rest. Both of these values are important to your physician in order to assess your cardiovascular health.

What is hypertension?

Hypertension is the medical term for high blood pressure, and is a result of elevated systolic and/or diastolic levels. While hypertension is often linked to family history and lifestyle, it is not uncommon for doctors to be unable to pinpoint the cause. In fact, many people diagnosed with hypertension had no risk factors prior. Thus, the disease has come to be referred to as “the silent killer.” Left untreated, high blood pressure may lead to more serious problems, such as kidney disease, heart attack, or stroke. A home blood pressure monitor is an excellent way to track your blood pressure; however, only a qualified physician can safely and accurately interpret the readings obtained from your monitor. Never attempt self-diagnosis or treatment of your symptoms. High blood pressure is best controlled under the supervision of your doctor.

I took my blood pressure and it was high !!
Should I be scared?
Scared, no. Concerned, yes.

Many things can affect blood pressure, such as stress, excitement, exercise and medication. It can also vary widely from day to day, and even hour to hour. Blood pressure is considered to be high when the systolic reading is 140 mmHg or above or the diastolic number is 90 mmHg or higher for an extended period. Your doctor will be able to make the diagnosis after taking several readings over a period of time. Always consult with your doctor regarding concerns about your blood pressure.

Why take your blood pressure at home?

Several clinical studies have shown improvement in detection and treatment of hypertension among people using a home blood pressure monitor, in conjunction with advice from their doctor. Some patients are anxious while having their blood pressure taken in a doctor’s office or hospital. This can cause elevated readings referred to as “white coat hypertension.” Conversely, blood pressure measurement at home tends to be more relaxed, limiting “outside” influences. Thus, a truer blood pressure history may be obtained.
