Relating your rotator cuff tear to your car accident can be extremely difficult. Because the majority of tears are caused by wear and tear, it's not uncommon for an insurance company to deny a person's claim and say that the car accident wasn't the cause.
Heart attacks. If your arteries become completely blocked, it can cause a heart attack (myocardial infarction). Heart attacks can permanently damage the heart muscle and, if not treated straight away, can be fatal. Dial 999 for immediate medical assistence if you think you're having a heart attack.
The outcome of a heart attack also depends on where the blockage is, whether the heart rhythm is disturbed, and whether another coronary artery supplies blood to that part of the heart. Blockages in the left coronary artery usually are more serious than in the right coronary artery.
