High blood pressure, also known as hypertension, is a widespread health issue that significantly increases the risk of heart disease, stroke, and other serious health problems.
For a long time, doctors have believed that it was crucial to keep both the top number (systolic) and the bottom number (diastolic) of a blood pressure reading within a specific range.
However, new research suggests that the top number, or systolic blood pressure, might be the most important factor to focus on when treating high blood pressure.
Blood pressure readings consist of two numbers: systolic and diastolic. Systolic blood pressure measures the force your heart uses to pump blood around your body, while diastolic blood pressure measures the pressure in your arteries when your heart rests between beats.
Traditionally, doctors have been taught to keep both numbers within a certain range to prevent complications. However, a new study suggests that it may be more important to focus on lowering systolic blood pressure and that the diastolic number might not be as critical as previously thought.
In this study, researchers from NUI Galway and other institutions analyzed data from over 47,000 patients around the world.
They wanted to understand how lowering blood pressure affects health outcomes, especially focusing on whether there is any harm in reducing the diastolic blood pressure too much.
Surprisingly, they found no evidence that lowering diastolic blood pressure to levels that were previously thought to be too low actually caused harm. This finding goes against what many doctors have believed for years.
As a result of these findings, the researchers suggest that doctors should focus on getting their patients’ systolic blood pressure to a level between 100 and 130 mmHg, without worrying too much about how low the diastolic pressure might go.
This shift in focus could change how doctors treat high blood pressure, potentially leading to better outcomes for patients.
By concentrating on systolic pressure, healthcare providers might be able to more effectively reduce the risks of heart attacks, strokes, and other problems related to high blood pressure.
Preventing high blood pressure in the first place is just as important as treating it. There are several steps that people can take to help prevent high blood pressure:
- Maintain a Healthy Weight: Carrying extra weight forces the heart to work harder, which can lead to high blood pressure. Keeping a healthy weight can reduce this risk.
- Eat a Healthy Diet: A diet that includes plenty of fruits, vegetables, whole grains, lean proteins, and low-fat dairy products can help keep blood pressure in check.
- Limit Sodium Intake: Eating too much salt can cause the body to hold onto water, which increases blood pressure. It’s important to keep sodium intake to less than 2,300 milligrams per day.
- Exercise Regularly: Regular physical activity helps keep the heart strong and can lower blood pressure.
- Limit Alcohol Consumption: Drinking too much alcohol can raise blood pressure. It’s recommended that men limit themselves to two drinks per day and women to one drink per day.
- Quit Smoking: Smoking damages the blood vessels and raises blood pressure. Quitting smoking can improve overall heart health and lower blood pressure.
- Manage Stress: Chronic stress can contribute to high blood pressure. Finding ways to manage stress, such as through meditation, yoga, or deep breathing exercises, can help.
- Get Regular Blood Pressure Checks: High blood pressure often has no symptoms, so it’s important to have it checked regularly. Early detection can lead to earlier treatment, which can reduce the risk of serious complications.
This recent study, led by Dr. Bill McEvoy and his team and published in the journal Circulation, could lead to a major change in how doctors treat high blood pressure.
By putting more emphasis on controlling systolic blood pressure, doctors may be able to better protect their patients from the dangers associated with hypertension.
In conclusion, while the traditional approach to managing high blood pressure involved careful attention to both systolic and diastolic numbers, this new research suggests that focusing more on systolic blood pressure might be the key to better treatment.
Combined with preventive measures and regular monitoring, this new approach could help more people avoid the serious health problems that high blood pressure can cause.
