I was wondering if anyone could tell ne the liklihood off some my age (31 year old female) having a ruptured aneurysm or a sudden cardiac arrest? I have extreme anxiety about these 2 things, to the point where i am scared to go to sleep for fear it will happen. I havent smoked for nearly 4 years but my grandfather died of a heart attack at 81 and my nanna had open heart surgery at 65. my cholesterol is good as is my blood pressure. I just want to stop feeling anxious about this
