Insights
The 2024 European Society of Cardiology (ESC) guidelines for elevated blood pressure (BP) and hypertension identify a broader population at increased cardiovascular disease risk. Elevated BP, as per ESC, is linked to a modestly higher risk of events like ischemic stroke.
Area of Science:
- Cardiology
- Public Health
- Epidemiology
Background:
- The European Society of Cardiology (ESC) updated blood pressure (BP) categorization in 2024 into non-elevated BP, elevated BP, and hypertension.
- Assessing the predictive value of these new ESC guidelines for future cardiovascular disease (CVD) risk is crucial.
Purpose of the Study:
- To evaluate if the 2024 ESC guidelines for elevated BP and hypertension accurately identify individuals at higher risk of future cardiovascular diseases.
- To compare risk stratification using the 2024 ESC guidelines versus the 2023 European Society of Hypertension (ESH) classification.
Main Methods:
- A population-based cohort study utilized data from the Korean National Health Insurance Service database (2009).
- Included were individuals aged ≥40 years without prior stroke or myocardial infarction, followed for a mean of 11.66 years.
- Multivariable Cox proportional hazards models assessed the association between BP categories and composite outcomes (stroke, myocardial infarction, all-cause mortality).
Main Results:
- The study analyzed 2,604,340 participants.
- Both elevated BP and hypertension groups, per ESC 2024, showed significantly higher risks for composite outcomes (aHR 1.072 and 1.201, respectively) compared to non-elevated BP.
- Risks for stroke, myocardial infarction, and all-cause mortality were significantly elevated in both the elevated BP and hypertension groups.
Conclusions:
- The 2024 ESC guidelines for elevated BP and hypertension are associated with an increased risk of future cardiovascular events.
- The ESC framework identified a broader at-risk population compared to the 2023 ESH classification.
- Individuals with elevated BP, as defined by ESC 2024, exhibit a modestly higher risk of cardiovascular events, particularly ischemic stroke.
Background And Aims:
The most recent guidelines from the European Society of Cardiology (ESC) categorize blood pressure (BP) into three groups: (1) non-elevated BP, (2) elevated BP and (3) hypertension. This study aimed to determine whether the 2024 guidelines from the ESC for elevated BP and hypertension accurately identify populations at increased risk of future cardiovascular diseases.
Methods:
In a population-based cohort derived from the Korean National Health Insurance Service database, we included individuals aged ≥40 years who underwent national health examinations in 2009. Those with a history of stroke or myocardial infarction were excluded. Multivariable Cox proportional hazards models were used to assess the association between blood BP categories and the risk of the composite outcome (stroke, myocardial infarction, and all-cause mortality). Risk estimates based on the 2023 European Society of Hypertension (ESH) classification were also analyzed to illustrate differences in categorization.
Results:
A total of 2,604,340 participants were included in the final analysis, with a mean follow-up duration of 11.66 ± 2.25 years. Compared to the non-elevated BP group, both the elevated BP and hypertension groups showed significantly higher risks for the composite outcome (adjusted hazard ratio [aHR] 1.072 (95% CI: 1.059-1.084) and 1.201 (95% CI: 1.186-1.217)). The risks of stroke, myocardial infarction, and all-cause mortality were likewise significantly elevated in both the elevated BP and hypertension groups, respectively. Applying both the ESC and ESH frameworks demonstrated how differing BP thresholds can result in variation in risk assessment across population subgroups.
Conclusions:
Elevated BP and hypertension, as defined by the 2024 ESC guidelines, were associated with increased risk of future cardiovascular events. While findings were directionally consistent with the 2023 ESH classification, the ESC framework identified a broader at-risk population. These results indicate that individuals with elevated BP, as defined by the 2024 ESC classification, have a modestly higher risk of cardiovascular events, particularly ischemic stroke, compared with those with non-elevated BP.
