High blood pressure, or hypertension, is a common health concern in Quebec. It refers to a sustained elevation of blood pressure in the arteries. Hypertension is generally diagnosed when systolic pressure exceeds 140 mmHg and/or diastolic pressure exceeds 90 mmHg, on multiple occasions.

It is often called a “silent condition” because it may cause no symptoms for years.

Possible Causes

Risk factors for high blood pressure include: family history, high-sodium diet, excess weight, lack of exercise, chronic stress, alcohol, smoking, or underlying conditions like kidney disorders.

Symptoms of High Blood Pressure

Although hypertension may be asymptomatic, some people may experience:

  • Headaches

  • Dizziness

  • Blurred vision

  • Unusual fatigue

  • Palpitations

Potential Complications

If left untreated, hypertension may contribute to serious complications like stroke, heart attack, kidney failure, or vision problems.

Prevention and Treatment

Ways to lower blood pressure include:

  • Reducing salt intake

  • Engaging in regular physical activity

  • Losing excess weight

  • Avoiding alcohol and tobacco

  • Managing stress

  • Following medical advice

Medical Imaging and High Blood Pressure

In certain situations, imaging tests may be recommended to evaluate the impact of hypertension or to investigate a possible secondary cause. Among these, cardiac ultrasound is useful for observing effects on the heart, while MRI or CT scans can help assess the brain, kidneys, or other organs. More targeted examinations, such as carotid ultrasound, allow an analysis of blood flow in the neck arteries, while Doppler ultrasound of the renal arteries can help detect a narrowing (stenosis) that may influence blood pressure.

These tests are not systematic. Their use depends on medical assessment and the clinical context of each patient.
