The AHA now recommends treating high blood pressure when it measures more than 130/80 mmHg, which is lower than the previous limit of 140/90 mmHg.

This is the first significant change in the US guidelines. UU Since 2003, it will likely increase the number of Americans diagnosed with the condition from 32% to 46%.

Why have the US guidelines changed? UU.? And if Singapore will not adopt the new definition of high blood pressure, do the new US guidelines? UU They mean something to you?

Dr. Paul Chiam, cardiologist at Mount Elizabeth Ninth Hospital, shares his thoughts and advice on the subject.

Basics of blood pressure

Technically, doctors measure their blood pressure twice. The systolic pressure measures the pressure in the arteries when the heart contracts . Diastolic pressure measures the pressure in the arteries as the heart relaxes.

Normal blood pressure is generally considered to be a systolic pressure less than 120 mmHg and a diastolic pressure less than 80 mmHg. [19659002] In the past, high blood pressure (medically known as hypertension) was not officially diagnosed until the systolic pressure exceeded 140 mmHg or the diastolic pressure exceeded 90 mmHg. All that changed with the new AHA guidelines.

In the new AHA guidelines, you are considered to have high blood pressure if your systolic blood pressure is 130 mmHg or more, or if the diastolic pressure is 80 mmHg or more.

Why did the blood pressure patterns change?

The Landmark Systolic Blood Pressure (SPRINT) intervention trial, which was published in 2015, suggests that adults with high blood pressure continue to benefit when their systolic pressure drops below the norm (120 mmHg).

Therefore, any measurement of systolic pressure above 130 mmHg puts a patient at greater risk of heart disease and its various complications.

With the new guidelines, doctors can intervene at an earlier stage.

Do Singapore's high blood pressure patterns change?

 are the Singapore guidelines that change
While the AHA has adjusted its guidelines, Singapore will not follow suit.

Singapore adheres to its definition of high blood pressure as when blood pressure is more than 140/90 mmHg, the Ministry of Health (MOH) said on November 16, 2017.

The MOH explained that the guidelines of the AHA were developed in the context of the population of the United States and that it would continue to review its applicability to the population of Singapore. They also noted that the revised guidelines do not change the focus of blood pressure management in an important way.

Dr. Paul Chiam shares his thoughts: "The aim of the new guidelines is to increase the awareness that a blood pressure of more than 130 / 80mmHg increases the risk of cardiovascular diseases and encourages us to be more aggressive with the modifications lifestyle changes such as diet, exercise and weight loss.

"For the majority of the general public, lifestyle modifications will suffice and medication will not be required if BP is between 130 – 140/80 – 90 mmHg. "

Specifically for Singapore, the implementation of these guidelines will be reduced to evaluating the supporting evidence and determining whether it will benefit the population as a whole.

" Meanwhile, the new AHA guidelines give everyone the important reminder that high blood pressure increases the risk of cardiovascular disease, "says Dr. Chiam." While a diagnosis of 130/80 mmHg of blood pressure will not necessarily result in the need to take medication, it does show us the importance to lead a healthy lifestyle. "

Exercising more, adopting a healthier diet, avoiding alcohol and salt foods, quitting smoking, losing weight, and minimizing stress can all help lower blood pressure.

] For many people, these modifications will be enough to achieve a healthier reading, Dr. Paul Chiam clarifies: "Your doctor will probably only recommend taking medications in this stage if you have already had a heart attack or stroke, or if you have a high risk of having one, for example, if you are diabetic. " [19659005] What should you do if you are worried about blood pressure?
