Insights

Systolic blood pressure below 130 mmHg is linked to higher mortality in heart failure with reduced ejection fraction (HFrEF) patients. This trend was also seen in heart failure with mid-range ejection fraction (HFmrEF), but not in HFpEF.

Area of Science:

  • Cardiology
  • Hypertension Research
  • Heart Failure Studies

Background:

  • Optimal systolic blood pressure (SBP) targets for hypertensive heart failure (HF) patients with varying ejection fractions (EF) are not well-established.
  • Previous studies have not adequately explored the relationship between SBP and mortality across different HF phenotypes.

Purpose of the Study:

  • To investigate the association between SBP levels and prognosis in hypertensive patients across all heart failure (HF) phenotypes.
  • To determine if SBP <130 mmHg impacts mortality differently in heart failure with reduced ejection fraction (HFrEF), mid-range ejection fraction (HFmrEF), and preserved ejection fraction (HFpEF).

Main Methods:

  • A retrospective cohort study analyzed 1279 hypertensive HF patients.
  • Patients were categorized into SBP <130 mmHg (383 patients) and SBP ≥130 mmHg (896 patients) groups.
  • The primary endpoint was all-cause mortality over a 1-year follow-up period.

Main Results:

  • In patients with HFrEF, SBP <130 mmHg was significantly associated with increased all-cause mortality (HR 2.53) and cardiovascular death (HR 1.91).
  • A trend towards increased mortality was observed in HFmrEF patients with SBP <130 mmHg, though not statistically significant.
  • No increased mortality risk was observed in HFpEF patients with SBP <130 mmHg.

Conclusions:

  • Lower systolic blood pressure (<130 mmHg) is linked to higher all-cause and cardiovascular mortality in hypertensive patients with HFrEF.
  • The association between lower SBP and mortality risk shows a trend in HFmrEF patients but is not evident in HFpEF patients.

Measurement of Blood Pressure01:17

Measurement of Blood Pressure

Assessing blood pressure is a standard procedure executed in virtually all medical environments. The method utilized today was established over a hundred years ago by an innovative Russian doctor, Dr. Nikolai Korotkoff. The soft ticking noise, known as Korotkoff sounds, heard while taking blood pressure readings results from turbulent blood flow within the vessels. The apparatus required for this procedure includes a sphygmomanometer, a blood pressure cuff attached to a gauge, and a...

Pathophysiology of Heart Failure01:17

Pathophysiology of Heart Failure

Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

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.

Blood Pressure01:24

Blood Pressure

The movement of blood in a human body, commonly referred to as blood flow, is determined by the volume of blood that traverses a certain section of the bodily system per unit time. It is the rhythmic contraction of the heart's ventricles that primarily instigates this movement. As the ventricles contract, blood is forced into the prominent arteries, which then flow from areas of greater pressure to lower pressure areas. This movement continues into smaller arteries and arterioles and...

Disorders of the Autonomic Nervous System

The autonomic nervous system (ANS) is an intricate network of nerves that controls functions such as the regulation of heart rate, digestion, and blood pressure regulation. When this system malfunctions, it can lead to various disorders that affect multiple bodily functions. One common feature of many autonomic disorders is the involvement of smooth blood vessels, which play a crucial role in regulating blood flow throughout the body.

Errors occurring during blood pressure monitoring01:25

Errors occurring during blood pressure monitoring

Blood pressure monitoring is a crucial clinical procedure in diagnosing and managing various cardiovascular conditions. Despite its significance, the accuracy of blood pressure measurements can be compromised by multiple factors, potentially leading to either falsely high or low readings. These inaccuracies are critical as they can significantly impact patient care. So, it is vital to understand these challenges deeply and adopt strategic approaches to minimize errors.
