Can waking up startled with a racing heart beat give you a heart attack or cardiac arrest? (awful feeling ex: alarm goes off=boom heart jumps) : (

Not in your case. In the absence of advanced heart disease it would be extremely rare. In a young female with no cardiac risk factors (diabetes, high blood pressure, cigarette smoking) not a problem. Try a clock radio with gentle music.
Not likely. Sounds like an anxiety reaction. Unless you are having multiple episodes during the day, it is unlikely to be a major problem. If you have a cardiologist, you may want to check it out with them.

Chronic disease. You don't have to worry about a heart attack, heart disease in the near future given your age. But you do need to treat your anxiety- to alleviate the symptoms of anxiety itself, and a lot of physical problems as your body is constantly exposed to stress hormones. See a psychiatrist.
Very very low. At 18, in the absence of other diagnosed heart conditions or significant family history... your chances are currently very, very low. Though anxiety is a crippling condition and can cause feelings of physical problems, you are at a very low risk of any heart issues. Don't let that compound your anxiety, but I would endorse you to get seen by a mental health professional for the anxiety.

Yes, though may ↓the. Severity. Xarelto does NOT thin the blood; blood viscosity does not change. Instead Xarelto inhibits clot formation, thus any bleeding problems are ↑ed.

Heart attacks are due to atherosclerosis & arterial lining ruptures; Xarelto is incapable of reducing these; only ↓es clotting.
