Does congestive heart failure cause a cough?

Chest congestion and heart failure are rarely thought to be associated with each other. Most individuals consider coughing as a respiratory issue. Few individuals, however, are aware that a persistent cough or congestion is also a sign of heart failure, which is clinically known as congestive heart failure (CHF).

Sometimes people with heart failure have a chronic cough that may also have some blood in it. This happens primarily when heart failure reaches an advanced stage. To live a healthy and secure life, people must understand whether their chronic cough indicates heart failure or not and, if it does, what actions to take.

Here is all one needs to know about the connection between cough and heart failure.

The connection between Heart Failure and Cough

Lung congestion is one of the potential problems that may arise with poor functioning of the heart muscle. This occurs when the blood coming back to the heart from the lungs tends to become backed up, leading to a condition where the fluid may leak into the lung airspace (alveoli). This congestion subsequently causes a cough.

Types of Cough in CHF

Various kinds of coughs that can be encountered by patients with congestive heart failure:

Dry, hacking cough:This is the most prevalent and occurs from fluid accumulation in the lungs.

Nocturnal cough:It tends to get worse during nighttime or when the individual rests in a horizontal position; therefore, some patients with CHF sleep in an inclined position with pillows. 

Productive cough with frothy sputum: In cases of severe or acute heart failure, this cough may indicate pulmonary edema and needs to be treated urgently.

Causes of congestive heart failure

Congestive heart failure can be caused by several conditions affecting the heart’s capacity to function as a good pump.

Conditions that lead to congestive heart failure can generally be classified into two types: conditions that are directly damaging the heart muscle, and conditions that overwork the heart by demanding more work.

Some of the common causes include:

• Coronary artery disease(CAD):CAD, which is the accumulation of plaque in coronary arteries, can result in reduced blood flow to the heart muscle, leading to heart muscle injury over time.
• Myocardial infarction (heart attack): A heart attack results when the blood supply to a segment of the heart muscle is cut off. The ensuing damage can weaken the pumping capacity of the heart, leading to heart failure.
• Hypertension:Repeated high blood pressure makes the heart work harder to circulate blood. Eventually, this may lead to heart failure.
• Heart valve disorders:Failing heart valves, such as aortic stenosis or mitral regurgitation, may put extra strain on the heart and cause heart failure.
• Infections:Viral infections, myocarditis or endocarditis may lead to inflammation and damage to the heart muscle and compromise its function as a pump
• Congenital heart malformations:Congenital abnormalities of heart structure can disrupt the normal function of the heart and cause heart failure in the long term.
• Diabetes:Uncontrolled diabetes and hypertension are risk factors got heart failure.
• Obesity: Being overweight may cause hypertension and diabetes, elevating the risk of heart failure.
• Thyroid imbalance: Hyperthyroidism (overactive thyroid) and hypothyroidism (underactive thyroid) can lead to heart failure if not well controlled.
• Alcohol and drug abuse: Alcohol use or abuse of some drugs can directly impact the heart muscle, leading to heart failure.
