Study to Assess Efficacy and Safety of SZC for the Management of High Potassium in Patients With Symptomatic HFrEF Receiving Spironolactone

Korábbi kezelés

• Systolic blood pressure <95 mmHg during the 6 hours prior to screening.
• Intravenous diuretic therapy during the 12 hours prior to screening.
• Use of intravenous inotropic drugs during the 24 hours prior to screening.
• Received mechanical circulatory support during the 48 hours prior to screening
• Previous cardiac transplantation or implantation of a ventricular assistance device (VAD) or similar device, or transplantation or implantation expected after randomisation

Más betegség

• Heart failure due to restrictive cardiomyopathy, active myocarditis, constrictive pericarditis, hypertrophic (obstructive) cardiomyopathy, or severe stenotic valve disease as a primary cause of HF
