Heart diseases
Donor eligibility
Loss of blood, for example through blood donation, may pose a significant risk to a person with cardiovascular disease and increase the risk of a heart attack, stroke or other serious event.
Individual assessment is needed. See list of heart diseases under "Please note".
Check medication, see list of medication.
Exceptions and comments
Please note:
Not eligible for blood donation if donor has / had, even though symptoms are not present. Permanent deferral:
Coronary artery disease or angina pectoris- regardless of cause, chest pain caused by narrowing of the coronary arteries or by angina pectoris, heart failure, heart valve disease, endocarditis, cardiomyopathy, right and/or left branch rupture of the heart, aneurysm, peripheral vascular disease including seizures or necrosis, heart surgery or surgery for blockage or narrowing of the vein, recurrent thrombosis or thrombosis, pacemaker, diagnosed with untreated arrhythmias (e.g. Atrial Fibrillation, Atrial Flutter, PSVT, Ventricular Tachycardia (VT) and ANTR).
PLEASE NOTE: If an exotic substance has been transplanted into the bloodstream, donation is not permitted.
Foramen Ovale (fetal orifice of the heart, PFO) can donate blood if asymptomatic and no treatment planned.
Endocarditis or infection of the heart valves: Not eligible for blood donation.
Known extra heart sounds on auscultation: Not eligible for blood donation if clinical symptoms are present. Permission to donate is most often given if a donor has few premature beats while resting.
Pericarditis: Can donate blood 12 months after recovery and in the absence of adverse reactions. Decision made with donor safety in mind.
Myocarditis: Can donate 12 months after full recovery if no symptoms are present. Decision made with donor safety in mind.
Mitral valve prolapse: Not eligible for blood donation. Permanent deferral. Decision made with donor health and safety in mind.
For other disease f. ex. Mitral stenosis, Blood unit doctor can permit donation, if no symptoms are present, if periodic monitoring without specific warnings from cardiologist or no monitoring is planned.
Cardiac surgery for congenital heart defect: Can donate blood if the heart defect has been corrected, donor is asymptomatic and is or has been monitored without special warnings from cardiologist.
AV-block - AV-block I and AV-block II type 1: Can donate blood if there is no need for treatment.
AV-block - AV-block II type 2 and AV-block III: Not eligible for blood donation. Permanent deferral. Decision made with donor safety in mind.
Bundle branch block: Not eligible for blood donation if heart disease present as well. Needs special approval from Blood unit doctor
Long QT syndrome: Can donate blood, even on preventive medication. Not eligible for apheresis.
Broken heart syndrome: Can donate blood 6 months after full recovery.
Implantable loop recorder (ILR: Can donate blood 1 month after removal of loop recorder.
Further information:
Patent Foramen Ovale (PFO) is a normal variation found in about 40% of individuals.
Angina, intermittent claudication: Pain and weakness in the feet (especially the calves) and limp occurs when walking that softens during rest. The cause is increased muscle ischemia due to circulatory artery dysfunction.
