Abstract
LM Surgery is defined as the lesion in the main stem of the LM coronary artery
greater than 50 percent in the coronary angiography or Ostial LAD and LCX
involvement (equivalent LM).
Emergency LM surgery is defined as Procedure required during first 24hr of
hospitalization to minimize chance of further clinical deterioration. Examples include
but are not limited to: Worsening, sudden chest pain, congestive heart failure, acute
myocardial infarction (AMI), anatomy, IABP, UA with intravenous NTG or rest
angina.
ACS is an important cause of death and morbidity among coronary artery disease
patients. In recent years, treatment of ACS patients was significantly improved,
leading to the decrease of in- hospital and long-term mortality and many of those
patients may need emergent or urgent revascularization by PCI or CABG due to ongoing
ischemia
The outcome of surgical revascularization for ACS has improved significantly
over last few decades. However, there are subgroups of patients who fare poorly
despite aggressive operative management, an increased mortality rate has been
reported in the published work for this group.
The indications for revascularization in patients with Severe Coronary Artery
Disease are persistence of symptoms despite medical treatment and/or improvement of
prognosis. ischemia is of prognostic importance in patients with Severe Coronary
Artery Disease, particularly when occurring at low workload. It demonstrated a
survival benefit from CABG in patients with LM or LM equivalent Artery Disease,
particularly when the proximal LAD coronary artery was involved. Benefits were
greater in those with severe symptoms, early positive exercise tests, and impaired LV
function. Based on the CASS registry. It has been suggested that two important
