About this study

Official title: Impact of Renin-Angiotensin System Inhibitors Continuation on Outcome After Major Surgery : a Multicenter, Prospective, Randomized and Controlled Trial

More than 200 million major surgical procedures are performed annually worldwide. Many of these patients have comorbidities including hypertension and/or heart failure. Chronic treatment of hypertension and/or heart failure very often includes a Renin-Angiotensin System (RAS) inhibitor (Angiotensin-Converting Enzyme Inhibitors (ACE-Is) or Angiotensin Receptor Blockers (ARBs). To stop or not to stop these medications before major surgery remain unknown. Data on management of RAS inhibitors before major surgery and anesthesia remain lacking and matter of debate. It is much likely that the strategy regarding management of RAS inhibitors in the peri-operative setting have important impact on peri-operative complications.

The lack of evidence leads to conflicting guidelines with respect to RAS inhibitors management before major surgery. While French guidelines are to stop RAS inhibitors patients with hypertension to avoid profound anesthestic-drugs-induced hypotension, international guidelines differ. The American heart association task force states that continuation of RAS inhibitors perioperatively is reasonable (class IIa recommendation,level of evidence: B). The purpose of this study is to determine the prognostic impact of withholding vs continuing ARBs before major non cardiac surgery.

Read the detailed description

Multicenter, prospective, randomized, pragmatic, parallel-group clinical trial. The inclusion visit takes place between 4 months and no later than 3 days before the surgery visit.

  • The randomization will be performed by the anesthesiologist Control group : RAS-I discontinuation Experimental group: RAS-I continuation
  • A prescription for the medication strategy (stopping or pursuing the medication) will be handed to the patient during the anesthesiology consultation.

Five follow-up visits are planned

  • Immediately, one hour after the surgery (Day 0)
  • Then four follow-up visits are planned on day 1, 2, 7 (or hospital discharge) and 28 days+15 days (43 days maximum) after surgery will be collected data and parameters for study endpoints.

End of research visit is the 28 days+15 days (43 days maximum) follow-up visit.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. composite outcome composed of all-cause mortality and major postoperative complications within 28 days after surgery.

    Complications will be validated by an adjudication committee, blinded to the treatment arm.

    Death; Acute Myocardial infarction; Arterial or venous thrombosis; Stroke; Acute pulmonary oedema; Post-operative cardiogenic shock; Acute severe hypertension crisis; Cardiac arrhythmia requiring therapeutic intervention; Postoperative episodes of sepsis; Postoperative respiratory complication; Need for unplanned intensive care unit admission or readmission; Acute kidney injury: KDIGO criteria Baseline serum creatinine is obtained from the pre-operative blood sample; Surgical complications: need for reoperation for any reason and radiologic interventions for abscess drainage; Severe Hyperkalemia: serum potassium level >5.5 mmol/L and requiring therapeutic intervention (insulin/glucose infusion and/or sodium bicarbonate infusion and/or intravenous B2 agonists and/or intravenous calcium gluconate and/or renal replacement therapy and/or ventricular tachycardia or ventricular fibrillation).

    Measured: after surgery until day 28

Secondary outcomes (5)
  1. Episodes of hypotension

    Episodes requiring vasopressors administration

    Measured: during anesthesia and surgery

  2. Acute kidney injury

    according to the KDIGO criteria

    Measured: after surgery until day 28

  3. Maximum SOFA score

    patients admitted to ICU

    Measured: from postoperative day 1 to day 7

  4. Duration of hospital stay

    Patients who will be outside the hospital but in other types of health care facilities at day 28 will be considered to have been discharged home

    Measured: after surgery until day 28

  5. Hospital free-days

    Duration after hospital discharge

    Measured: censored at 28 days following surgery

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03374449, which also lists 9 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 May 2024; AzTrials last refreshed its copy on 8 Nov 2026.
