What are the 4 stages of congestive heart failure?
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.
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.
Shortness of breath can be a symptom of conditons affecting lungs and heart, allergic reaction or anaphylaxis, sudden blood loss, anemia, Anxiety, Foreign body or choking which needs to be evaluated and treated accordingly
Every shortness of breath must be evaluated to know the cause and give appropriate treatment. Some of the conditions which cause shortness of breath are allergic reaction or anaphylaxis, sudden blood loss, anemia, Anxiety, Foreign body or choking, lung infections like pneumonis, Fluid in lung, Collapse lung, Blood clot in lung vasculature like Pulmonary embolism, Asthma, COPD, Pregnancy, Heart attack or failure, Heart rhythm irregularity.
You may check breathing or oxygenation level by "Pulse Oximeter" which gives indirect clue on lung damage but keep in mind there are other medical conditions which may affect pulse oximeter readings.
From limited research done, coffee consumption was associated with some positive effects on the respiratory system. Few small studies have shown coffee was associated with reduction of asthma and coffee with natural honey was effective for persistent post-infectious cough. There was however limited available evidence to establish its effects.
