11. Persistent Cough.
It is likely that you get a cough a few times per year when the cold months are taking effect. A cough in this case is due to bacteria invading your throat lining and irritating these tissues. This type of cough is very commonly resolved in a week or two, but if you notice that you have a cough that has persisted for months (a regular, heavy, and dry cough), then this could be an indicator for heart failure. Heart failure occurs when your heart is unable to pump blood throughout your body and this is found through an echocardiogram. Your ejection fraction is the determining marker of heart failure and if you notice that you have a persistent cough, consider making an appointment to see your doctor.
