Death caused by non-coronary, non-CNS vascular conditions such as pulmonary embolism, ruptured aortic aneurysm, dissecting aneurysm, or other vascular disease. Death from vascular CNS causes ○ From haemorrhagic stroke, ○ From ischaemic stroke. All procedure-related deaths (see definition below), including those related to a complication of the procedure or treatment for a complication of the procedure. Sudden or unwitnessed death defined as non-traumatic, unexpected fatal event occurring within 1 h of the onset of symptoms in an apparently healthy subject. If death is not witnessed, the definition applies when the victim was in good health 24 h before the event. Death of unknown cause.
Non-cardiovascular mortality	Death of a primary cause that is clearly related to another condition (e.g. trauma, cancer, suicide).
