Growing concerns over COVID-19 have health care organizations worldwide making vast changes ― from postponing procedures to visitation restrictions. Consumers are being asked to limit emergency room visits.

But every day, people have medical emergencies that may require urgent intervention.

"You should not go to the emergency room for every sniffle or cold, but there are things that warrant medical attention and should not be ignored," says Dr. David A. Miller, director of the Comprehensive Stroke Center at Mayo Clinic in Florida.

While people with preexisting conditions are at a higher risk to develop more severe consequence to COVID-19, which may include shortness of breath, it's also important to recognize respiratory issues may be a sign of a heart attack, too. "If you experience symptoms consistent with a heart attack or stroke, it's important not to ignore them. There are treatments for heart attack and strokes that are effective if they are initiated in a short time after the symptoms start."
