Symptom 6. Persistent Cough: An Unwanted Companion
In the seemingly unrelated world of respiratory symptoms, a persistent cough could be one of the key indicators of acute heart failure. This isn’t your run-of-the-mill seasonal cough or a residual tickle in the throat after a common cold. This is a relentless, nagging cough that seems immune to the soothing effects of regular cough suppressants.
When we think of heart failure, a persistent cough isn’t usually the first symptom that comes to mind. But there’s a logical connection between this relentless cough and the failing heart. With the heart’s reduced pumping capacity, fluid can back up into the lungs. This fluid accumulation, known as pulmonary edema, hampers the lungs’ ability to facilitate the exchange of gases.
In an attempt to expel this excess fluid, the body may resort to coughing. This isn’t the sporadic coughing fit you might experience when you swallow water the wrong way. It’s a continuous, tiresome cough that can persist for weeks. It may be worse at night or when lying flat, as these positions allow fluid to spread out in the lungs, which triggers the cough reflex.
Moreover, this cough could produce frothy sputum or, in severe cases, sputum tinged with blood. It’s an alarming symptom that signifies a significant dysfunction in the body. This isn’t a symptom you can dismiss or mask with over-the-counter remedies. It’s a clear sign that something is seriously wrong. (6)
