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.
This test, often called an echo, shows your heart's movement. During this exam, your doctor places a wand on the surface of your chest. It sends ultrasound waves that show pictures of your heart's valves and chambers. Those images let your doctor look at how well your ticker is pumping. Your doctor may combine an echocardiogram with tests called Doppler ultrasound and color Doppler to check blood flow across your heart's valves. Ejection fraction (EF). It's a measure of how much blood is pumped out of your heart each time it beats.
