"A simple blood test costing less than $10 could prevent hundreds of heart attacks and other adverse cardiac events per year.

Troponin is a protein found in heart muscle cells that if detected in the blood stream means the heart has been damaged in some way: a key indicator of cardiovascular disease risk with greater predictive power than cholesterol levels.

A troponin detection test that can be administered along with other simple blood tests could alert hundreds of patients to their higher risk of heart attack and stroke, allowing them to alter their lifestyle or even start taking statins, in advance of an adverse cardiac event.

The concept was demonstrated in a paper published in the Journal of the American College of Cardiology. The authors showed that adding cardiac troponin levels to existing risk factors such as smoking status, cholesterol, diabetes presence, and blood pressure increased the predictive powers of these screenings—done after CVD events or in advance of a statin prescription.

In fact, in their study of 62,000 Britons with a 15-year follow-up, one additional CVD event would be prevented for every 408 and 473 individuals screened when troponin was added, a result of troponin being a good indicator of so-called “silent” heart damage that could lead to a CVD event in the future.

The study also found adding troponin tests meant that up to 8% of people classified as intermediate risk were changed to high-risk.

“Troponin, even in the normal range, is a powerful indicator of silent heart muscle damage,” said Anoop Shah, a professor of cardiovascular medicine at the London School of Hygiene & Tropical Medicine and lead author on the study.

“As such, the test provides an extra layer of information that we can use to boost our accuracy when predicting people’s risk. We want to identify as many high-risk people as possible, so that no one misses out on the opportunity to get preventative treatment.”"

Wish me luck since I'm going to my first ever cardiology appointment, and I wished I had done this sooner in 2022-2023.

I lost a relative who most likely passed away suddenly in his sleep in December 2022 at the age of 24; he died without explanations!! 😢. From what I've learned, he was an athlete who played basketball. Please be aware of your health to get your checkups and that your life is so fragile here on earth. I've done some research if it was a common thing for athletes to have cardiac health issues and their mortality behind it all from studies. I just had a vague memory that my cousin might've had some kind of respiratory condition---maybe asthma?

The Role of the Sympathetic vs. Parasympathetic Nervous System in POTS Patients

Understanding the Autonomic Nervous System and POTS

The autonomic nervous system (ANS) plays a crucial role in regulating involuntary bodily functions such as heart rate, blood pressure, digestion, and temperature control. It consists of two primary branches:

The Sympathetic Nervous System (SNS) – Also known as the "fight or flight" system, the SNS increases heart rate, blood pressure, and alertness, especially when standing or during stress.

The Parasympathetic Nervous System (PNS) – Often called the "rest and digest" system, the PNS works to slow the heart rate, aid digestion, and promote relaxation.

In Postural Orthostatic Tachycardia Syndrome (POTS), an imbalance between these two systems is a key contributor to symptoms like tachycardia, dizziness, and fatigue. Understanding how sympathetic overactivity and parasympathetic dysfunction influence POTS is essential for effective treatment.

Sympathetic Nervous System Overactivity in POTS

In many POTS patients, particularly those with hyperadrenergic POTS, the sympathetic nervous system becomes overly active. This results in:

Excessive heart rate increase upon standing (tachycardia), often greater than 30 beats per minute in adults or 40 bpm in adolescents.

Elevated norepinephrine levels in the bloodstream, which can cause symptoms like anxiety, tremors, palpitations, and blood pressure fluctuations.

Vasoconstriction or poor regulation of blood flow, leading to blood pooling in the lower extremities and making it difficult to maintain proper circulation.

Excessive sweating and temperature regulation issues.

This sympathetic overactivity can create a cycle of worsening symptoms, further stressing the cardiovascular system and worsening POTS symptoms.

Parasympathetic Dysfunction and POTS

On the other hand, impaired parasympathetic activity in some POTS patients can lead to:

Reduced heart rate variability (HRV), making it harder for the body to adjust heart rate and blood pressure in response to changes in position.

Digestive issues like nausea, bloating, and gastroparesis (delayed stomach emptying) due to insufficient vagal nerve function.

Temperature regulation problems, including cold extremities or excessive sweating.

Because the parasympathetic nervous system helps regulate relaxation and recovery after stress, its dysfunction can leave POTS patients feeling constantly fatigued, stressed, and overstimulated.

Balancing the Autonomic Nervous System: Treatment Approaches for POTS

Given that sympathetic overactivity and parasympathetic dysfunction both contribute to POTS, treatment often focuses on rebalancing the autonomic nervous system. Some key strategies include:

Medications: Drugs such as beta-blockers to help reduce sympathetic activity, and fludrocortisone to increase blood volume, can be used to manage symptoms.

Lifestyle modifications: Increasing salt and fluid intake, wearing compression garments, and avoiding prolonged standing can help stabilize circulation and manage blood pressure.

Autonomic rehabilitation programs: Gradual, supervised exercise helps improve cardiovascular fitness and autonomic function by improving heart rate variability and enhancing blood flow regulation.

Vagal nerve stimulation techniques: Practices like deep breathing, biofeedback, and relaxation techniques can enhance parasympathetic nervous system activity and support overall autonomic function.

POTS is intricately connected to dysfunction within both the sympathetic and parasympathetic nervous systems. By understanding how these two branches of the autonomic nervous system interact, patients and healthcare providers can work together to develop a comprehensive and personalized treatment plan. If you or someone you know is experiencing symptoms of POTS, consulting an autonomic specialist can help restore balance and improve overall health and quality of life.

Frequently Asked Questions (FAQs)

1. How does the sympathetic nervous system contribute to POTS symptoms?

In POTS, the sympathetic nervous system (SNS) becomes overactive, causing a rapid increase in heart rate upon standing and elevated levels of norepinephrine. This leads to symptoms like palpitations, anxiety, tremors, and blood pressure fluctuations.

2. What happens when the parasympathetic nervous system is not functioning properly in POTS?

Impaired parasympathetic nervous system (PNS) function can lead to difficulties in regulating heart rate, blood pressure, and digestion. Patients may experience dizziness, fatigue, and digestive issues like gastroparesis.

3. Can POTS be diagnosed through testing for autonomic dysfunction?

Yes, diagnosis of POTS often involves autonomic function testing, including the tilt table test and heart rate monitoring to assess how the SNS and PNS respond to stress or position changes.

4. Are there medications that can help balance the sympathetic and parasympathetic nervous systems?

Yes, medications like beta-blockers (to reduce SNS overactivity) and fludrocortisone (to increase blood volume) are commonly used in the management of POTS. Other medications may help regulate fluid balance and support parasympathetic function.

5. How can exercise help with autonomic dysfunction in POTS?

Gradual, supervised exercise helps improve cardiovascular fitness and heart rate variability (HRV), which can enhance autonomic regulation. A tailored exercise program is often recommended to help retrain the autonomic nervous system.

6. What lifestyle changes can assist in managing POTS symptoms?

Lifestyle changes that support circulation and autonomic balance include increasing fluid and salt intake, wearing compression stockings, and avoiding prolonged standing. Positional changes and specific exercises can also help improve symptoms.

7. Is POTS a lifelong condition?

While POTS is often a chronic condition, many patients experience significant improvements in symptoms with the right treatment, lifestyle modifications, and physical therapy. Early diagnosis and intervention are critical to improving long-term outcomes.

8. Can POTS be linked to other conditions?

Yes, POTS can sometimes develop secondary to conditions like autoimmune diseases, diabetes, or Ehlers-Danlos Syndrome (EDS). Treating the underlying condition is crucial to managing POTS symptoms effectively.
