Palpitations, Nausea, Coughing, and Wheezing After Stent Placement - Cardiology

Understanding the symptoms of palpitations, nausea, coughing, and wheezing after stent placement is crucial for both patients and healthcare providers. Your experience, particularly after undergoing stent placement, raises several important considerations regarding the interplay of cardiovascular and gastrointestinal symptoms.

Palpitations, which you describe as "漏拍" (missed beats), can often be benign, especially if they are identified as premature contractions, as your physician indicated. Premature ventricular contractions (PVCs) or premature atrial contractions (PACs) are common and can occur in healthy individuals. They may be exacerbated by stress, anxiety, or physical exertion, which aligns with your observation that symptoms arise during activities like climbing stairs or lifting heavy objects.
The nausea and vomiting you experience, particularly when they occur alongside palpitations, could be related to several factors. One possibility is that the vagus nerve, which plays a role in heart rate regulation and gastrointestinal function, is being stimulated during episodes of palpitations or anxiety. This could lead to a reflex that causes nausea or even vomiting. It’s also worth noting that the stress response can trigger gastrointestinal symptoms, which might explain why you feel nauseous during tense situations or while watching a movie.

Coughing and wheezing can be more complex. These symptoms may indicate an underlying respiratory issue, such as reactive airway disease or bronchospasm, particularly if they occur during physical exertion. However, they could also be linked to anxiety or a heightened state of arousal, which can cause hyperventilation and lead to feelings of breathlessness or wheezing.
The fact that your symptoms sometimes resolve after severe vomiting is intriguing. This could suggest that the act of vomiting provides some relief from the vagal stimulation or pressure on the diaphragm, which may temporarily alleviate the palpitations or respiratory symptoms.
Given that multiple specialists have evaluated your condition without finding significant abnormalities, it may be beneficial to consider a multidisciplinary approach. Here are some recommendations:
1. Cardiology Follow-Up: Continue to monitor your heart health with regular check-ups. If symptoms persist or worsen, further investigations such as a Holter monitor (which records heart activity over 24 hours) or an electrophysiological study might be warranted.

2. Gastroenterology Consultation: Since gastrointestinal symptoms are prominent, a gastroenterologist may explore functional gastrointestinal disorders, such as gastroparesis or esophageal motility disorders, which could contribute to nausea and vomiting.

3. Pulmonology Evaluation: If coughing and wheezing persist, a pulmonologist could assess for asthma or other respiratory conditions. A spirometry test may help evaluate lung function.

4. Psychological Support: Given the anxiety component, consider speaking with a mental health professional. Cognitive-behavioral therapy (CBT) or relaxation techniques may help manage anxiety and its physical manifestations.

5. Lifestyle Modifications: Incorporate stress-reducing activities such as yoga, meditation, or regular exercise, which can improve both cardiovascular and gastrointestinal health.

6. Dietary Considerations: Pay attention to your diet, as certain foods may exacerbate gastrointestinal symptoms. Keeping a food diary could help identify potential triggers.

In conclusion, while your symptoms may seem interconnected, they could arise from multiple systems in the body reacting to stress or underlying conditions. A comprehensive approach involving various specialties may provide a clearer understanding and lead to effective management strategies. Always ensure to communicate openly with your healthcare providers about your symptoms and any changes you notice.
