[44F] With progressively worsening shortness of breath and associated symptoms

What might be happening

Based on the symptoms you've described, several potential diagnoses could explain your condition. Here are the most likely ones:

1. Heart Failure

Given your history of endocarditis and fast heart rate, heart failure is a significant concern. Heart failure can cause:

• Shortness of breath: This is often worse with activity or when lying flat.
• Fatigue: Due to the heart's reduced ability to pump blood effectively.
• Chest pain: Can occur due to the heart struggling to meet the body's demands.
• Palpitations: Irregular or fast heartbeats are common.
• Nausea and loss of appetite: Reduced blood flow to the digestive system can cause these symptoms.

2. Coronary Artery Disease (CAD)

CAD could also explain your symptoms, especially given the chest pain and shortness of breath. CAD occurs when the blood vessels supplying the heart become narrowed or blocked, leading to:

• Chest pain: Often described as pressure or tightness, sometimes radiating to the arm, back, or shoulder.
• Shortness of breath: Due to reduced oxygen supply to the heart.
• Fatigue and dizziness: Resulting from poor blood flow.

3. Arrhythmias

Irregular heart rhythms (arrhythmias) could be causing your palpitations, dizziness, and shortness of breath. Arrhythmias can result from various heart conditions, including those you've mentioned.

4. Anxiety or Panic Disorders

While less likely given your history and symptoms, anxiety or panic disorders can cause:

• Shortness of breath
• Chest pain
• Palpitations
• Dizziness and light-headedness

What you can do

Shortness of breath and chest pain

• Seek immediate medical attention: Given the severity and persistence of your symptoms, it's crucial to see a healthcare provider as soon as possible. These symptoms could indicate a serious heart condition that requires prompt evaluation and treatment.
• Limit physical activity: Until you can see a doctor, try to avoid activities that exacerbate your symptoms.
• Elevate your head while sleeping: This can help reduce shortness of breath when lying flat.

Fatigue and palpitations

• Monitor your symptoms: Keep a journal of when these symptoms occur, their severity, and any potential triggers. You can use MDandMe to track your symptoms and share this information with your healthcare provider.
• Stay hydrated: Dehydration can worsen palpitations and fatigue.

Nausea and loss of appetite

• Eat small, frequent meals: This can help manage nausea and ensure you're getting enough nutrients.
• Avoid lying down immediately after eating: This can help reduce nausea.

Headaches

• Continue taking Tylenol as needed: Ensure you follow the recommended dosage and consult your doctor if headaches persist or worsen.

What you should look out for

Given the severity of your symptoms and the potential for serious underlying conditions, you should seek medical care as soon as possible. Reasons to seek care even more urgently include:

• Severe chest pain: Especially if it radiates to your arm, back, or shoulder.
• Fainting or severe dizziness
• Sudden worsening of shortness of breath
• New or worsening palpitations
