Understanding Hypertension

Hypertension is a chronic disease characterized by consistently high blood pressure over time. It is one of the main risk factors for cardiovascular disease. Ever on the rise, it is now one of the leading causes of premature death worldwide according to the World Health Organization1. When detected at an early stage and treated appropriately, hypertension is a condition that can be managed very well.

Mine’s 120 over 80, what about you?

The first number refers to systolic pressure — the pressure exerted on the arteries with each heartbeat (systole).
The second number refers to diastolic pressure — this is the pressure in the arteries when the heart relaxes (diastole). Even when the heart is at rest, a certain amount of pressure must be maintained in the arteries to prevent them from “collapsing,” in the other words, narrowing or closing in.

A reading of 120/80 corresponds to a systolic pressure of 120 mm Hg and a diastolic pressure of 80 mm Hg (12 millimeters of mercury = 120 mm Hg; 8 millimeters of mercury = 80 mm Hg).
This is considered a “normal” blood pressure. Hypertension is diagnosed when blood pressure is equal to or greater than 140 over 901.

High blood pressure has become the most common chronic condition in the country. It is estimated to affect nearly one in three adults (29%)2.

Patients with high blood pressure may experience dizziness, headaches, palpitations , but this is rarely the case. More often than not, hypertension has no symptoms. Taking one’s blood pressure may therefore be the only indicator of this condition, so it is important to have it checked regularly by a health care professional. Likewise, raiseing awareness among your loved ones about the importance of regular monitoring is crucial.

Screening is a quick and painless process, and the results are known immediately.

You can also have your blood pressure taken in a pharmacy, or on your own using a portable blood pressure monitor and then discuss the readings with your doctor.

Although there is no apparent cause of hypertension, several factors increase the risk. For example, a diet too rich in salt, fat or sugar, lack of physical activity, stress, smoking, excessive alcohol consumption, being overweight, etc. Through lifestyle changes, it is possible to take direct action to lower one’s blood pressure.

However, some factors cannot be controlled, such as:

  • Age: 40% of 65-year-olds and 90% of 85-year-olds are at risk of suffering from hypertension3.
  • Family history: The existence of family history doubles the risk of hypertension and increases the likelihood of developing it at a younger age.
  • Certain diseases or treatments whichmay lead indirectly to hypertension – such as renal insufficiency or hyperthyroidism.

The combination of these factors reduces the efficiency of blood circulation and makes the heart muscle work harder. Over time, excessive pressure on the heart weakens arteries, making them stiff and potentially resulting in atheromatous plaques (build-up of cholesterol on the artery walls). A hypertensive patient has fragile arteries and a heart that is fatigued.

REMEMBER

  1. Take your blood pressure regularly. Hypertension is a silent, but dangerous condition. Although effective medication exists, if hypertension is not detected, it cannot be treated. That’s why you should monitor your blood pressure to identify the condition early on and manage it properly.
  2. Take your medication as directed. If you are already on medication for hypertension, follow it carefully. Adherence is essential to ensuring treatment success and preventing complications. Appropriate treatment can improve your quality of life.
  3. Trust your loved ones. They can encourage you to stick with your treatment and take care of your health.

ABOUT SERVIER

We are the leading global pharmaceutical group in hypertension and rank 5th in cardiology3. For over 70 years, we have been committed to addressing cardiovascular diseases, including hypertension.

As the profiles of hypertensive patients vary, we are working on more personalized solutions to improve therapeutic adherence. For example, we are capitalizing on our expertise in cardiometabolism, with the development of Single Pill Combinations (SPC) or fixed-dose combinations. Treatments that combine several active ingredients in a single tablet.

We also fully support the May Measure Month screening initiative organized by the International Society of Hypertension (ISH). For several years now, we have committed to improving hypertension screening through our #BecauseISaySo global awareness campaign. Its purpose is to give patients the information and tools they need to make checking their blood pressure a habit.

Finally, our MyHealthPartner website is dedicated to patients suffering from hypertension as well as their loved ones and health care professionals. It provides a wealth of information on chronic diseases and in particular, hypertension.
