After your visit

Keep the plan going between appointments

Cardiology care is mostly what you do between visits. Patterns in heart rate, blood pressure and symptoms over weeks tell your cardiologist far more than a single reading in the office. Apple Health already records much of this; the trick is seeing it next to how you felt. Emerge Care, free to download on iPhone, is built for exactly that: tell it how you feel in your own words, get plain answers with the source behind every fact, and walk into your next cardiologist appointment with Dr. Marcu with a one-page summary and your questions ready.

  • Log symptoms and side effects by talking
  • Answers that name their source
  • One-page visit summary PDF
  • Health records stay on your iPhone
