1 Angina Pectoris: It is described as a pain located at the back of the breast bone which may be sharp or dull. This sensation may radiate or crawl to the hand, arm, left shoulder, or jaw.  Vasculitis: When the small to medium sized arteries are inflamed, head tingling and numbness may result.
Most species of shark eat things like fish, crustaceans, mollusks, plankton, krill, marine mammals and other sharks. Sharks also have a very acute sense of smell that allows them to detect blood in the water from miles away.
A PET scan shows if your heart is getting enough blood or if blood flow is reduced because of narrowed arteries. It also shows dead cells (scars) from a prior heart attack. A PET scan can help in determining if youâll benefit from a cardiac procedure (PCI) or surgery to restore blood flow. The tracers used for PET scans can help identify injured but still living (viable) heart muscle that might be saved if blood flow is restored.
