A key consideration for women regarding coronary artery disease is that:

• A. Women have larger hearts leading to less occlusion risk
• B. Women's hearts are smaller, leading to increased risk of vessel occlusion
• C. CAD is less common in women and not a concern
• D. Women have greater collateral circulation providing complete protection

Answer: (B)

The main idea here is that women often have smaller coronary arteries, which can make the same amount of plaque more likely to narrow or block a vessel. When the lumen is smaller, plaque buildup reduces flow more quickly, so occlusion risk is higher even if the overall amount of disease isn’t greater than in men. The radius of a vessel has a big impact on blood flow, so smaller vessels have less reserve and are more susceptible to significant obstruction. This isn’t about heart size or universal protection by collateral vessels. Heart size isn’t the determining factor for occlusion risk, and CAD is still a important concern for women, though it can present with atypical symptoms. Collateral circulation varies among individuals and does not guarantee complete protection in all women.
