The information indicates some blood vessel blockage of the heart locations given. Whether or not it is an event depends on your symptoms and whether or not the blockage has caused heart cell damage. Vessel blockage can cause symptoms such as chest pain (angina pectoris), etc. If there has been an event of heart cell damage there can be loss of heart pumping contractility causing shortness of breath, muscle fatigue, chest pain...signs would be an increase in wall dimensions of the left ventricle, reduced cardiac output, etc,
Hope this helps, and if you have any further questions or comments you are welcome to respond. Take care,
