Insights

Hypertension increases heart failure risk. Different guidelines define hypertension differently, impacting risk assessment. This study compared ACC/AHA and ESC/ESH guidelines, finding both identify key blood pressure categories linked to heart failure development.

Area of Science:

  • Cardiology
  • Epidemiology
  • Public Health

Background:

  • Hypertension is a major risk factor for heart failure (HF).
  • Discrepancies in hypertension definitions across international guidelines complicate risk stratification for HF prevention.
  • Standardized identification of blood pressure (BP) categories for HF prevention is needed.

Purpose of the Study:

  • To investigate the association between hypertension, as defined by the 2017 American College of Cardiology/American Heart Association (ACC/AHA) and 2018 European Society of Cardiology/European Society of Hypertension (ESC/ESH) guidelines, and the risk of developing heart failure (HF).

Main Methods:

  • A prospective cohort study involving 2809 randomly selected urban Japanese participants from the Suita Study.
  • Cox regression analysis was employed to calculate hazard ratios (HRs) and 95% confidence intervals (95% CIs) for HF risk across different BP categories.
  • BP categories were compared against a reference of systolic BP <120 mmHg and diastolic BP <80 mmHg, with a median follow-up of 8 years.

Main Results:

  • During the follow-up, 339 cases of heart failure were identified.
  • According to ACC/AHA 2017 guidelines, hypertension stages I and II and isolated systolic hypertension were significantly associated with increased HF risk (HRs ranging from 1.64 to 1.81).
  • According to ESC/ESH 2018 guidelines, high-normal BP, hypertension stages I, II, and III, and isolated systolic hypertension were associated with elevated HF risk (HRs ranging from 1.51 to 2.57).

Conclusions:

  • Hypertension and isolated systolic hypertension, as defined by both ACC/AHA 2017 and ESC/ESH 2018 guidelines, are confirmed risk factors for heart failure.
  • High-normal blood pressure, per the ESC/ESH 2018 guidelines, also emerged as a significant risk factor for heart failure.
  • These findings underscore the importance of guideline-specific BP management for heart failure prevention.

Heart Failure IV: Classification and Diagnostic Evaluation

Heart failure can be classified in various ways, with the most common classifications based on physical activity limitations, disease progression, severity, and treatment strategies.The Functional Classification of Heart Failure divides patients into four categories based on physical activity limitation due to symptom burden.Class I: Patients in this class have cardiac disease but no physical activity limitations. Ordinary activities like walking, climbing stairs, or routine tasks do not cause...

Special considerations while measuring blood pressure

When assessing blood pressure (BP), healthcare professionals must consider various factors and potential unexpected outcomes to ensure accurate readings and provide proper patient care. Adhering to these guidelines is essential to achieving the most reliable results.
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
