Insights

Angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) do not increase the risk of COVID-19 infection or hospitalization, regardless of medication dose. These findings support continued use of ACEIs and ARBs for patients.

Area of Science:

  • Cardiovascular Medicine
  • Infectious Diseases
  • Pharmacology

Background:

  • Angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) are commonly prescribed cardiovascular medications.
  • Previous research has raised concerns about potential links between ACEIs/ARBs and increased risk or severity of coronavirus disease 2019 (COVID-19).
  • The impact of medication dosage on these potential risks has not been thoroughly investigated.

Purpose of the Study:

  • To investigate the association between the use of ACEIs and ARBs and the risk of COVID-19 infection.
  • To examine whether medication dose influences the risk of COVID-19 infection or hospitalization.
  • To provide evidence-based recommendations for patients taking ACEIs and ARBs during the COVID-19 pandemic.

Main Methods:

  • Retrospective cohort study of over 322,000 individuals in a US healthcare system.
  • ACEI and ARB use and standardized daily doses were determined from pharmacy data.
  • COVID-19 infection and hospitalization data were collected through June 2020; logistic regression was used for analysis.

Main Results:

  • No significant association was found between ACEI/ARB use and COVID-19 infection (adjusted OR 0.91; 95% CI 0.74-1.12).
  • Medication dose did not alter the risk of infection; adjusted ORs for infection ranged from 0.89 to 0.92 across different dose categories.
  • No association was observed between ACEI/ARB use and COVID-19 hospitalization (adjusted OR 0.98; 95% CI 0.63-1.54).

Conclusions:

  • Current use of ACEIs and ARBs is not associated with an increased risk of COVID-19 infection or hospitalization.
  • These findings support existing clinical guidelines recommending the continuation of ACEIs and ARBs for patients.
  • The study provides reassurance regarding the safety of these medications in the context of the COVID-19 pandemic.

Antihypertensive Drugs: Direct Renin Inhibitors

The renin-angiotensin-aldosterone system (RAAS) is an intricate physiological pathway involving numerous enzymes and hormones, including renin, angiotensin-converting enzyme (ACE), angiotensin I and II, and aldosterone. Imbalances within this system increase the production of angiotensin II and aldosterone. Increased angiotensin II levels promote vasoconstriction and blood pressure elevation. Concurrently, higher aldosterone levels stimulate sodium and water reabsorption in the kidneys,...

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System

The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...

Antihypertensive Drugs: Angiotensin-Converting Enzyme Inhibitors

Angiotensin-converting enzyme (ACE), a vital component of the renin-angiotensin-aldosterone system, is abundant in lung endothelial cells. ACE converts the inactive decapeptide, angiotensin I, into the active octapeptide, angiotensin II. This potent vasoconstrictor narrows blood vessels, increasing resistance to blood flow and elevating blood pressure. Angiotensin II also stimulates aldosterone production, encouraging kidney cells to reabsorb more sodium and water from urine, thereby increasing...

Antihypertensive Drugs: Angiotensin II Receptor Blockers

In the renin-angiotensin-aldosterone system, a hormone called angiotensin II plays a crucial role. It binds to the AT1 receptors in vascular smooth muscles coupled with Gq proteins. The activation of these receptors activates an enzyme called phospholipase C, which releases two molecules: inositol trisphosphate and diacylglycerol. These molecules cause a chain reaction that leads to the phosphorylation of myosin light chains and promotes interaction between actin and myosin, leading to smooth...
