Why Cardiology Matters

Cardiology consistently appears as one of the top-tested subjects on USMLE Step 1, accounting for approximately 15-20% of questions. A solid understanding of cardiac physiology, pathology, and pharmacology is essential for a high score.

The SuperPoints Approach

The key to mastering cardiology is building a strong foundation first, then layering clinical details on top. Start with the SuperPoint concept for each topic — one powerful sentence that captures the core idea.

Study Order

  1. Cardiac physiology and the cardiac cycle
  2. Heart failure pathophysiology
