Overview. Currently, STEMI remains an electrocardiographic diagnosis, despite failing to encompass all forms of total occlusive disease.2 In patients with total artery occlusions who do not meet STEMI criteria as in some LCX occlusions delayed PCI poses a significant risk for mortality and morbidity. Note that the discussion so far only concerns the left ventricle. Circumflex coronary arteries encounter a common problem called atherosclerosis, which results in severe heart problems. It provides oxygenated blood to most of the left ventricle, which is the main pumping chamber of the heart. Hence, ST-segment elevations in leads V3V4 are caused by transmural ischemia located in the anterior wall of the left ventricle.
