A weak heart causes fluid to back up in the lungs. This can cause shortness of breath with exercise or difficulty breathing at rest or when lying flat in bed. Lung congestion can also cause a dry, hacking cough or wheezing.
Heavy breathing accompanied by spells of wet cough with frothy sputum that may be tinged with blood is called as "Cardiac cough or Heart cough". It is a sign of congestive heart failure. Additional symptoms such as shortness of breath on exertion or rest, leg swelling, waking up from sleep in the middle of night gasping and coughing differentiate heart cough from cough due to lung conditions.
Heart attack feels like pressure on chest cannot be relieved by antacids,associated with breathlessness. One can not entirely differentiate chest pain due to gas from chest pain due to heart attack based on symptoms only. You may need to visit a hospital and get evaluated by a health-care provider.
High amounts of salt, sugar, saturated fat, and refined carbs raise your risk for a heart attack or stroke.
Four stages of congestive heart failure are Stage A, B, C, D. Stage A and B are pre heart failure stages when persons do not have symptoms but have predilection to heart failure such as Diabetes, Hypertension, obesity, alcohol abuse, heart blocks and family history of heart failure. Stage C is when persons have symptoms, diagnosed with heart failure and responding to treatment. Stage D is when persons have advanced symptoms that may not get better with treatment.
