[60M] With labile blood pressure and premature atrial contractions

Patient Description

A 60-year-old male has been experiencing fluctuations in blood pressure for the past three years, with episodes occurring about once a week and lasting three to four hours. These fluctuations have not been stabilized by any measures. The patient also experiences premature atrial contractions (PACs) approximately 16% of the time. He reports occasional dizziness or lightheadedness when his blood pressure is low and he stands up, but denies any chest pain or shortness of breath. There is no use of tobacco, alcohol, or recreational drugs, and no family history of heart disease, stroke, or hypertension. The patient's diet consists of a good mix of healthy foods with no recent changes. He has a history of Zenker's diverticulum, for which he has had three surgeries since being diagnosed in 2021. Current medications include venlafaxine (150mg daily), clonazepam (1mg as needed), metoprolol (50mg daily), and terazosin (10mg daily). There have been no recent changes in medications or dosages, and he does not take any over-the-counter medications, supplements, or herbal remedies. No known drug allergies.

Arora's Assessment

What might be happening

Based on the information you have provided, here are some possible explanations for your symptoms:

  • Premature Atrial Contractions (PACs): PACs are early heartbeats originating in the atria. They are common and often benign but can be bothersome. They may be related to stress, caffeine, or other stimulants, but in your case, no specific triggers have been identified.

    • Treatment: PACs often do not require treatment if they are not causing significant symptoms. However, beta-blockers like metoprolol, which you are already taking, can help reduce their frequency.

  • Labile Blood Pressure: This refers to blood pressure that fluctuates significantly. It can be influenced by various factors, including stress, anxiety, and certain medications. Given your history of taking venlafaxine (an antidepressant) and clonazepam (an anti-anxiety medication), these could potentially contribute to blood pressure variability.

    • Treatment: Managing labile blood pressure often involves lifestyle modifications, such as reducing stress, maintaining a healthy diet, and regular exercise. Your current medications, including metoprolol and terazosin, are also used to manage blood pressure.

What you can do

While it's important to consult with your healthcare provider for a formal assessment and personalized treatment plan, here are some general tips that might help:

  1. Monitor Your Blood Pressure: Keep a daily log of your blood pressure readings, noting the time of day and any associated symptoms. This information can be valuable for your healthcare provider.
  2. Lifestyle Modifications:
    • Diet: Continue eating a balanced diet rich in fruits, vegetables, whole grains, and lean proteins. Limit salt, caffeine, and alcohol intake.
    • Exercise: Engage in regular physical activity, such as walking, swimming, or yoga, which can help stabilize blood pressure.
    • Stress Management: Practice relaxation techniques like deep breathing, meditation, or mindfulness to help manage stress.
  3. Medication Adherence: Take your medications as prescribed and discuss any side effects or concerns with your healthcare provider.
  4. Symptom Tracking: Use MDandMe to journal your symptoms, track your progress, and share longitudinal medical notes with your provider. This can help identify patterns and triggers.

What you should look out for

Seek medical attention if you experience any of the following:

  • Severe or Worsening Symptoms: If your blood pressure becomes extremely high or low, or if you experience severe dizziness, fainting, or palpitations.
  • New Symptoms: If you develop chest pain, shortness of breath, or any other new or concerning symptoms.
  • Medication Side Effects: If you notice any adverse effects from your medications, such as extreme fatigue, swelling, or unusual changes in mood or behavior.

Remember, while this advice can help manage your symptoms, it's essential to consult with your healthcare provider for a comprehensive evaluation and personalized treatment plan.
