Can Fatigue and Weakness Be Related to Your Heart?

Persistent fatigue and weakness can stem from many different causes, and in some cases may be related to blood flow to the heart. This page looks at this symptom's possible connection to the heart and how it may be evaluated as part of a conversation about EECP.

How to Tell If Fatigue May Be Heart-Related

Fatigue That Increases With Exertion

Fatigue that appears earlier than expected during everyday activities may sometimes be related to blood flow to the heart.

Occurring Alongside Shortness of Breath

Fatigue accompanied by shortness of breath is a combination that may call for a cardiology evaluation.

Limits on Daily Activities

A growing sense of fatigue during tasks that used to feel easy is a finding worth paying attention to.

Other Possible Causes

Non-cardiac causes such as anemia, thyroid problems, and sleep disturbances can also lead to fatigue, which is why a proper differential diagnosis matters.

How EECP Is Considered for Fatigue Complaints

Planned Once the Underlying Cause Is Known

EECP may be considered as an option once fatigue has been assessed and found to be related to the heart.

Aims to Support Blood Flow

Some patients report a positive change in their daily energy levels after blood flow to the heart has been supported through treatment.

A Cardiology Evaluation Comes First

Before EECP is ever planned, the cause of the fatigue is investigated through a thorough medical evaluation.

Considered Alongside Lifestyle

Sleep quality, nutrition, and physical activity levels all play an important role in managing fatigue as well.

Who Typically Considers an EECP Evaluation

Fatigue Linked to a Known Heart Condition

Patients whose fatigue is associated with a known heart condition often begin by discussing EECP with their cardiologist.

Limited Exertion Capacity Despite Medication

Those whose exertion capacity remains limited despite medication may benefit from a conversation about EECP.

Deemed Suitable by the Cardiology Team

Ultimately, patients considered good candidates by their cardiology team are the ones for whom EECP is planned.

Fatigue and weakness can stem from a wide range of causes. EECP may be an option only in cases assessed to be heart-related, and under the guidance of a cardiology team — it is not, on its own, a method of diagnosis or treatment.
