Unfortunately, many individuals improperly diagnose their condition when they are really encountering sleep "dyspnea"... aka shortness of breath.. This condition can be caused by several different factors... Worst case being--> A strong indication of heart disease or eventual congestive heart failure... so yes.. certain abuse of steroids can amplify this consequence, where a disruption in the normal circulation of blood can cause the heart to not efficiently circulate your blood to all necessary organs... eventually--> lungs will not receive enough blood (which provides oxygen) that enables proper gaseous exchange....causing retention of extracellular fluid in lungs (and even more backed up pressure in either ventricle of the heart (extra pressure forces muscles of heart to enarge and stiffen --in order to adapt to this)... this can happen in many other major organs as well!! Bottom line... This breathing condition can possibly be an indication of several other complications and your heart rate does not have to be abnormal for this condition to exist!!
