Brazilian Society of Cardiology changes high blood pressure diagnosis guideline

A Brazilian Society of Cardiology (SBC ) released new guidelines for taking pressure measurements. Therefore, guidelines for diagnosing high pressure have been changed.

The new standard was presented during the 1st Meeting of Cardiology Departments, which began this Friday (12). The event runs until tomorrow (13).

The document that establishes this is “the Brazilian Guidelines for Blood Pressure Measurements Inside and Outside the Office”. The document was prepared by 67 professionals.

The guidance was made for doctors and healthcare professionals – therefore, nothing changes for patients, only for those who provide the care.

“High blood pressure is one of the main modifiable risk factors for morbidity and mortality worldwide, being one of the biggest risk factors for coronary artery disease, cerebrovascular accident (CVA) and kidney failure,” the entity said in a release.

According to the SBC report “Cardiovascular Statistics of the Brazilian Society of Cardiology 2023”, around 23.93% of the Brazilian population has hypertension – that is, high blood pressure.

According to the SBC, hypertension is more common among people over 65 years of age. The prevalence of high blood pressure was estimated at 61% of this population.

According to doctor Audes Feitosa, coordinator of the new guidelines, the objective of the new guidelines is “to guide doctors and patients to increase the effectiveness of methods for assessing blood pressure also outside of offices”, which “is a fundamental agenda for an effective population approach about this important cardiovascular risk factor in Brazil and around the world”.

Ambulatory Blood Pressure Monitoring (ABPM) and Home Blood Pressure Monitoring (MRPA) and Blood Pressure Self-Measurement (AMPA) are the main methodologies for monitoring Blood Pressure outside the doctor's office. These techniques help in creating a more accurate and assertive diagnosis to identify cases of hypertension.

With the new guidelines, the objective is to detect common variations such as white coat hypertension (WHA), masked hypertension (MH), changes in blood pressure during sleep and resistant arterial hypertension (RH), undetected conditions with monitoring restricted to offices. .

“These new guidelines offer a highly qualified technical and scientific basis to guide managers, doctors and other health professionals”, informed Feitosa.

The document shows that the use of inappropriate techniques or equipment can result in incorrect diagnoses. With the new “Brazilian Guidelines for Blood Pressure Measurements Inside and Outside the Office”, the SBC advises doctors not to determine that the final diagnosis is based on a single measurement – ​​mainly because the indicators are variable.

“Pressure levels that do not fit into stage 3 in an office environment, for example, must be reevaluated in subsequent measurements for diagnostic confirmation, as well as to define the stage of hypertension”, explained Feitosa in the document sent to the press.

“Office measurements are subject to numerous biases (systematic errors) and the use of other measurement methods for diagnosis are necessary”, informed the entity.

A new feature of the new version of the document is that the SBC guides doctors to look at gender, age group, social class and various health conditions.
