Can Autonomic Nervous System Disorders Cause Mitral Valve Prolapse?

Can autonomic nervous system dysfunction lead to mitral valve prolapse?

I would like to ask the doctor whether autonomic nervous system dysfunction can lead to mitral valve prolapse (which was previously normal).
After experiencing hyperventilation during two driving episodes, my body became tense, and I developed uncomfortable symptoms such as palpitations.
I consulted a Western medicine doctor who arranged a series of tests, including blood tests, an electrocardiogram, and a stress test, which revealed mild mitral valve regurgitation.
I was prescribed Inderal and Xanax to help reduce my heart rate and alleviate anxiety, but my autonomic nervous system dysfunction has not improved significantly.
I believe many people in today's society face similar issues and feel trapped in this situation.
I have researched and found that most individuals with this condition are congenital and asymptomatic.
I also understand the importance of the heart's role in mental well-being as described in Traditional Chinese Medicine (TCM), which differs significantly from Western medicine's perspective.
I read a book by an experienced TCM practitioner that mentioned acquired mitral valve issues can be repaired through TCM.
The China Medical University’s TCM department has many cases of recovery related to this issue.
I would like to ask the doctor if TCM can lead to complete recovery in this case.
I am 174 cm tall, weigh 68 kg, and am generally healthy, with normal blood test results and blood pressure; however, my heart rate can sometimes be elevated after the onset of symptoms.

1.
Mitral valve prolapse is the most common heart valve disorder, affecting 3-6% of the population.
Patients with mitral valve prolapse may experience symptoms such as nonspecific, vague chest pain, palpitations, heart racing, arrhythmias, or a feeling of tightness in the chest.
Discomfort in the chest may also be accompanied by dizziness, shortness of breath, or anxiety.
The incidence in young women is twice that of men.
Most patients with mild mitral valve prolapse remain asymptomatic throughout their lives, with only a small percentage (1%) progressing to severe mitral regurgitation, infective endocarditis, arrhythmias, sudden cardiac death, or cerebrovascular embolism.
Clinically, patients with "mitral valve prolapse" may not exhibit any symptoms, and a few patients may be diagnosed through specific heart murmurs detected by experienced cardiologists during auscultation, followed by echocardiography.
2.
Although the vast majority of individuals are asymptomatic, a minority may present with symptoms of "mitral regurgitation," leading to arrhythmias, chest pain, or even syncope; however, cases of sudden cardiac death due to "mitral valve prolapse" are rare.
Generally, asymptomatic "mitral valve prolapse" can be treated with traditional Chinese medicine, while patients with symptoms may receive regular pharmacological treatment (such as Inderal) from cardiologists.
Patients who have developed mitral regurgitation must undergo regular annual follow-up examinations; a few cases may lead to endocarditis or even heart failure due to impaired cardiac contraction, necessitating consideration for surgical replacement of the mitral valve.
3.
In summary, "mitral valve prolapse" is merely an anatomical abnormality of the heart.
If there are no specific clinical symptoms, patients need not be overly alarmed or worried; however, since these patients often experience some degree of psychological anxiety, mild sedatives or traditional Chinese medicine can help alleviate mental stress.
Patients with mitral valve prolapse should have annual echocardiograms and take precautions against infective endocarditis.
A balanced diet, avoidance of caffeine-containing stimulants, and regular exercise can help relieve symptoms of mitral valve prolapse.
4.
It is recommended to consult a qualified traditional Chinese medicine practitioner for appropriate differential diagnosis and treatment.
In my clinical practice, I often provide tonics to nourish heart qi or promote blood circulation and remove stasis, using herbal formulas that invigorate qi and blood to enhance cardiac vitality and improve the condition.
If there are concerns regarding chest tightness or pain, and medication does not improve the symptoms, further evaluation through specialized cardiac examinations is advisable to better understand the condition and avoid misdiagnosis or inappropriate treatment.
Finally, I wish you well.

More Info

Mitral valve prolapse (MVP) is a condition where the valve between the heart's left atrium and left ventricle does not close properly, which can lead to a range of symptoms, including palpitations, anxiety, and even chest pain. The relationship between autonomic nervous system (ANS) disorders and MVP is complex and multifaceted.

Firstly, it is important to understand that the autonomic nervous system regulates involuntary bodily functions, including heart rate, blood pressure, and the functioning of the heart valves. When there is a dysfunction in the ANS, it can lead to symptoms such as palpitations and anxiety, which you have experienced. These symptoms can sometimes mimic or exacerbate the sensations associated with MVP.
Research has shown that individuals with MVP often report symptoms related to anxiety and panic attacks, which can be linked to autonomic dysfunction. The ANS is divided into two main branches: the sympathetic nervous system, which prepares the body for 'fight or flight' responses, and the parasympathetic nervous system, which promotes 'rest and digest' functions. An imbalance in these systems can lead to increased heart rate and feelings of tightness or discomfort in the chest, which you described as feeling "tense" and experiencing "palpitations."
While MVP is often considered a structural issue, it is also influenced by the autonomic nervous system. In some cases, individuals with MVP may have a heightened sensitivity to stress or anxiety, which can trigger or worsen symptoms. This is particularly relevant in your case, where you mentioned experiencing symptoms after episodes of hyperventilation while driving. Hyperventilation can lead to a cascade of physiological responses, including increased heart rate and anxiety, which may exacerbate MVP symptoms.

Regarding the potential for complete recovery from MVP through traditional Chinese medicine (TCM), it is essential to approach this with caution. TCM emphasizes the balance of the body's energies and may offer supportive therapies that can help alleviate symptoms associated with anxiety and stress. However, MVP is primarily a structural condition, and while TCM may provide symptomatic relief and improve overall well-being, it may not be able to "repair" the valve in the same way that surgical interventions or medical management can.

In your case, the medications prescribed, such as Inderal (a beta-blocker) and Xanax (an anti-anxiety medication), are commonly used to manage symptoms associated with MVP and autonomic dysfunction. These medications can help regulate heart rate and reduce anxiety, which may improve your overall quality of life. However, if you find that your symptoms persist despite treatment, it may be beneficial to explore additional therapeutic options, including cognitive behavioral therapy (CBT) or other forms of psychotherapy, which can help address the anxiety component.

In conclusion, while autonomic nervous system disorders can contribute to the symptoms associated with mitral valve prolapse, they are not typically the direct cause of the structural issue itself. It is essential to work closely with your healthcare provider to monitor your condition and adjust your treatment plan as necessary. Additionally, exploring complementary therapies, such as TCM, may provide additional support, but it is crucial to maintain realistic expectations regarding the potential for structural repair. Always consult with your healthcare provider before making any changes to your treatment regimen.
