Irregular Heartbeat
There are plenty of reasons your heart might palpitate. Typically, an adrenaline rush or mood change can cause this symptom. You should probably be worried if it happens often with no recognizable reason. Arrhythmia, the medical term for it, can be a serious issue if it is not treated in time. What makes it so bad is that it can cause stroke as well.

Persistent Coughing
No one likes persistent coughing, least of all when you are the one with it. While it might not feel like it is something serious, it might be a sign of heart disease. When it is hard for the heart to deliver blood to the rest of the body, this can make it difficult for the lungs. If there is sputum, you should be concerned if it looks pink-white. Another cause of concern is a cough that intensifies when you are lying down in bed.
