Heart attacks and strokes are American epidemics. Together, they strike millions of Americans every year and take hundreds of thousands of lives. Both conditions are caused by arterial blockages. When oxygenated blood can’t make it to the heart or brain, heart muscles or brain cells begin to die off very quickly. Failure to get emergency medical care can lead to long-term disability and even death. PhysiciansER offers this infographic which explains the differences between these two serious conditions and highlights the common symptoms of each. If you suspect that you or a loved one is suffering a heart attack or stroke, call 911 and get to the nearest emergency room as quickly as possible. This information can save lives, so please pass it along to as many people as you can.
