Total occlusion of left main coronary artery in Orientals: profile of 4 cases.
The authors report 4 Oriental cases of total occlusion of the left main coronary artery (LMCA) with differing presentations. The first patient had a twelve-year history of stable angina pectoris. The second patient had angina for a year, which became unstable two months prior to diagnosis. The third patient had myocardial infarction seven years ago and presented with a one-month history of rest angina. The fourth patient had stable effort angina for six years but presented with accelerated angina three months prior to diagnosis. The incidence of total occlusion of the LMCA is rare and survival depends on the existence of collateral circulation. In LMCA disease, there is usually disease in other parts of the coronary arterial tree, and hence, the need for urgent coronary bypass surgery.
