Cardiac Sarcoidosis – All You Need to Know and Some Exciting News

Sarcoidosis is an inflammatory autoimmune disease characterized by the formation of granuloma, primarily in the lungs. It can affect any organ in the body.

In this article we will look into sarcoidosis with heart involvement, the basic facts but also the exciting news in the treatment of the disease.

Part 1. Frequency of cardiac sarcoidosis

It was first estimated that five in every hundred patients with sarcoidosis develops heart involvement. But recently, there have been studies that show evidence that the number is actually much higher, even 20 to 30.

Part 2. Survival expectancy in cardiac sarcoidosis

This is something that has generated a lot of opinion clashes. Studies show that the 77 % of sarcoidosis related death is due to heart sarcoidosis. The reported 5-year life expectancy in cardiac sarcoidosis is 40 to 50%.

Part 3. Diagnosis of cardiac sarcoidosis

It is not easy to diagnose cardiac sarcoidosis. The symptoms range from arrhythmias and chest pain and even heart block or heart failure. More details please visit:-

Some tests that you can expect if your doctor suspects of cardiac sarcoidosis.

  • Electrocardiography (ECG or EKG)
  • Holter monitoring
  • Nuclear imaging (with thallium)
  • Cardiac positron emission tomography (PET)
  • Heart biopsy
  • Echocardiography
  • Cardiac magnetic resonance imaging (MRI)

Part 4. Electrocardiographic abnormalities

Common ECG manifestations of cardiac sarcoidosis are: Rhythm disturbances, premature ventricular contractions and ST-T wave changes.

Part 5: Occurrence of sudden death in heart sarcoidosis

Of all the deaths that happen due to heart sarcoidosis 35 to 65% are sudden deaths due to ventricular tachyarrhythmias.

Part 6: Simulated Myocardial Infarction

This is fairly rare in patients with heart sarcoidosis but is recorded in medical practice.

Part 7. Other manifestations and heart sarcoidosis

Patients with cardiac sarcoidosis may present with an illness resembling acute myocarditis and occasionally patients have ventricular aneurysm.

Part 8. Exciting news in the field of alternative treatment of sarcoidosis research
