It causes the same symptoms as a heart attack caused by a blockage in a different artery, including chest pain, chest heaviness, shortness of breath, lightheadedness and cold sweats. During the surgery, a bypass is created by grafting a piece of a vein above and below the blocked area of a coronary artery, enabling blood to flow around the blockage. A blood clot can form on the plaque deposits, rapidly closing the artery and interrupting blood flow to the heart muscle. Neck or jaw pain. However, the same is NOT true for most blocked heart arteries discovered by stress-testing when the patient is not having a heart attack.

Shortness of breath. Stress test (also called treadmill or exercise ECG). The fatty deposits may develop in childhood and continue to thicken and enlarge throughout the life span. It is a benign incidental finding; however some patients present with sudden onset chest pain mimicking acute coronary syndrome often resulting in detection of this rare anatomy on coronary angiography. Coronary angioplasty. 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. Pain radiating in the neck, jaw, shoulders and arms or in the back portion.
