Patients can still be included in the DECONGEST study after withholding these diuretics for 6 h, after which randomisation can be performed if they qualify all other criteria.

  • Systolic blood pressure <90 mmHg, mean arterial pressure <65 mmHg, or need for inotropes/vasopressor therapy at randomisation
  • Any acute coronary syndrome within 30 days prior to enrolment, defined as typical chest pain with a troponin rise above the 99th percentile of normal and/or electrocardiographic changes suggestive of cardiac ischemia
  • History of heart or kidney transplantation
