Insights

Blood pressure control declined during the COVID-19 pandemic and had not fully recovered by 2022. This study highlights the ongoing impact of the pandemic on hypertension management and patient outcomes.

Area of Science:

  • Cardiovascular Health
  • Public Health Surveillance
  • Hypertension Management

Background:

  • The COVID-19 pandemic led to observed reductions in blood pressure (BP) control among hypertension patients.
  • The extent of BP control recovery to pre-pandemic levels remained undetermined.

Purpose of the Study:

  • To assess the recovery of blood pressure control to pre-pandemic levels by the end of 2022.
  • To analyze trends in BP control from 2017 to 2022.

Main Methods:

  • Utilized electronic health record data from 17 health systems within the National Patient-Centered Clinical Research Network.
  • Included individuals aged 18-85 with hypertension, analyzing BP control over 12-month rolling periods from 2017 to 2022.
  • Compared average BP control in 2022 to 2019, adjusting for demographic factors and by race and ethnicity.

Main Results:

  • In 2022, weighted average BP control was 62.6%, a decrease from 65.3% in 2019 (adjusted difference: -2.6 percentage points).
  • BP control dropped to 61.8% in 2020 and showed partial recovery by 2022.
  • Non-Hispanic Asian individuals experienced the most significant decline in BP control, from 68.4% in 2019 to 63.9% in 2022.

Conclusions:

  • Blood pressure control was significantly disrupted by the COVID-19 pandemic.
  • Pre-pandemic levels of BP control were not fully restored by the end of 2022.
  • Continued monitoring is essential to track persistent BP control declines and potential future cardiovascular events.

Blood Pressure01:30

Blood Pressure

Blood pressure (BP) is the pressure or force of blood exerted on the artery's walls as it circulates through the body. It is essential for maintaining blood flow throughout the body.
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the...

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...

Hypertension and Regulation of Blood Pressure01:18

Hypertension and Regulation of Blood Pressure

Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...

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...

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.
