Harjeet Singh: If these negotiations do not help countries to deal with the real impacts of climate change, and only prioritize emission targets, they will have failed the very people this agreement is meant to protect.
Blood tests. When your heart muscle has been damaged, as in a heart attack, your body releases substances in your blood. Blood tests can measure the levels of these substances and show if, and how much of, your heart has been damaged. The most common test after a heart attack checks levels of troponin in your blood.
During the test, a specialized dye will be injected into your bloodstream. The dye is then viewed under a special camera in a hospital or testing facility. A heart CT scan may also be called a coronary CT angiogram, if it is meant to view the arteries that bring blood to your heart. It may be called a coronary calcium scan if it meant to determine whether there is a build-up of calcium in your heart.
