The Philippine Heart Center is the premier cardiac institution in the country. The international mortality rate from CABG has seen a steady decline from the 1970's to the 1990's due to advancement in the field. Currently, according to the Society of Thoracic Surgeons database, the overall operative mortality rate for CABG is about 3%. It is the objective of this study to determine the in-hospital crude mortality rate for adult patients who underwent CABG from 2011 to 2015. This is a retrospective descriptive study covering 2011-2015 including all in-hospital mortalities of patients 19 years old and older who underwent CABG. There were a total of 3,450 CABG surgeries done from 2011 to 2015 with 117 mortalities. The in-hospital mortality rate of the Philippine Heart Center for the last 5 years being 3.39% is more than the international mortality rate of 3% but it is important to take note that from 2013 to 2015, the mortality rate is pegged at 3%. Being a high-volume, specialized government center in the age of evidence-based medicine, it would be prudent to explore the idea of creating a database that would be looked into by an expert panel to further improve protocols and outcomes.
