[2025-10-02T07:49:31.289307] [PI reasoning] **Determining cardiac afterload index**

I'm working on the multiple-choice question about the best index to measure cardiac afterload. Afterload represents the load the heart has to work against. For the left ventricle, it's often approximated by mean arterial pressure or systemic vascular resistance. The common exam answer indicates that mean arterial pressure is the best index of afterload. It seems like the answer is likely A. I’ll need to find some supporting citations to confirm this.
