About this trial
Anaemia is common in patients with acute coronary syndrome (ACS) and is associated with significant recurrent bleeding risk and major adverse cardiovascular event (MACE). Esophageal-gastro-Duodenoscopy (EGD) is commonly used as an initial investigation for anaemia but is often non-diagnostic. Magnetically Controlled Capsule Endoscopy (MCCE) being less invasive and with comparable diagnostic accuracy as EGD, might be used as an alternative initial investigation for anaemia in patients with ACS.

Disqualifiers
