Heart Function: Anxiety, Ejection Fraction, and Symptoms - Cardiology

More Info

---

Understanding heart function, particularly in the context of anxiety and ejection fraction (EF), is crucial for managing both physical and mental health. Ejection fraction is a measurement of the percentage of blood that is pumped out of the heart's left ventricle with each contraction. A normal EF ranges from 55% to 70%. When EF is lower than this range, it can indicate heart dysfunction, which may lead to symptoms such as fatigue, shortness of breath, and even palpitations.

Anxiety can significantly impact heart function and symptoms. When a person experiences anxiety, the body enters a state of heightened arousal, which can lead to increased heart rate and blood pressure. This physiological response can cause palpitations, which are often described as a feeling of the heart racing or fluttering. While anxiety itself does not directly lower EF, the stress it induces can exacerbate existing heart conditions or lead to a perception of heart issues, making the individual more aware of their heart rate and rhythm.

Regarding your concern about whether anxiety can cause fluctuations in EF, it is important to note that while acute stress can temporarily affect heart function, chronic anxiety may lead to long-term changes in cardiovascular health. Factors such as increased heart rate and blood pressure during anxiety episodes can strain the heart over time, potentially impacting its efficiency. However, if your EF has been improving, it is a positive sign that your heart is functioning well despite the anxiety.

Palpitations can indeed influence the perception of heart function. When experiencing palpitations, especially in the context of anxiety, it may feel as though the heart is not pumping effectively. However, unless there is an underlying heart condition, these palpitations are often benign and do not necessarily correlate with a decrease in EF.

Ejection fraction can change due to various factors, including:
1. Heart Conditions: Conditions such as coronary artery disease, heart valve issues, or cardiomyopathy can lead to a decrease in EF.

2. Fluid Status: Changes in body fluid levels, such as dehydration or fluid overload, can affect heart function.

3. Medications: Certain medications can influence heart rate and contractility, potentially impacting EF.

4. Physical Activity: Regular exercise can improve heart function and EF, while a sedentary lifestyle may have the opposite effect.

5. Stress and Anxiety: As mentioned, these can lead to temporary changes in heart function.

If your ejection fraction were to decrease, you might notice symptoms such as increased fatigue, shortness of breath, or swelling in the legs and ankles. However, the degree of discomfort can vary widely among individuals.

Regarding your spinal curvature, scoliosis can affect the position of the heart, but it typically does not have a significant impact on heart function unless there are severe structural changes. If your spine is causing discomfort or affecting your breathing, it might be worth discussing with a healthcare provider.

As for your medication, if you are taking anxiety medication like "景安寧" (likely a form of benzodiazepine), it can help manage anxiety symptoms, which may indirectly benefit your heart health by reducing stress-related palpitations. However, it's essential to follow your doctor's guidance regarding dosage and duration of use.

In summary, while anxiety can influence heart function and symptoms, it is crucial to maintain a holistic approach to your health. Regular follow-ups with your healthcare provider, managing anxiety through therapy or medication, and maintaining a healthy lifestyle can all contribute to better heart health. If you have concerns about your heart or anxiety, do not hesitate to reach out to your healthcare provider for personalized advice and reassurance.
