Correlation Between Mitral Annulus Calcification, Severe Coronary Artery Lesion and Cardiac Adverse Events in Acute Coronary Syndrome Patients Who Underwent Emergency PCI

Mitral annular calcification (MAC) is described as the chronic degenerative calcification of fibrous tissue mostly at the posterior leaflet of mitral valve and less often at the anterior leaflet of the same valve. Observational studies found that MAC was associated with incident coronary artery disease (CAD), cardiovascular (CV) mortality, stroke, new-onset AF and severity of atherosclerosis. The aim of this work was to assess the predictive value of MAC for major adverse cardiovascular events (MACE) in patients presenting with acute coronary syndrome (ACS).Patients and Methods: This prospective observational study was carried out on a total of 100 consecutive patients with Acute Coronary Syndrome Patients (ACS) who were admitted to Cardiology department in Banha University Hospital, Kaliobeya , Egypt and/or Agouza Police Hospital, Giza, Egypt and were undergone percutaneous coronary intervention (PCI) and thay divided into 2 groups : Patients with moderate to severe MAC group (41 patients) and Patients with No or Mild MAC group (59 patients).Results: Congestive heart failure was insignificantly different between two groups.
