7. Lightheadedness
In addition to other signs such as chest discomfort or irregular heartbeat, feeling lightheaded may also suggest having a heart attack. “It could mean your blood pressure has dropped because your heart isn’t able to pump the way it should,” Bufalino says.
8. Long-lasting Cough
If you’re suffering from a long-lasting cough, it might not just be a common cold. What’s more, if you find white or pink mucus with the coughing, it might indicate heart failure. Still, check with your doctor and get proper treatment for unrecognizable causes.
