Of the 865 with angiogram, one patient died and one had a major cerebrovascular accident and then died. Hence no procedure was planned. The denominator for this table is therefore 863. A further three had no details of the extent of the disease.
CABG, coronary artery bypass graft; PCI, percutaneous coronary intervention.
