Rationale

The integration reinforces the existing point about PVR's utility in calcified vessels by adding specific clinical context (diabetes and CKD) and a high-quality 2025 ACC guideline citation. Abbreviations (PVR, PAD, MAC, ABI) were expanded on first use as per instructions.

* ProvidesPulse volume recording (PVR) provides waveform analysis of segmental volume changes.changes during the cardiac cycle.
* Flattened or dampened waveforms =indicate severesignificant peripheral arterial disease (PAD).
* Advantage:A primary advantage of PVR is that it is not affected by calcification.medial arterial calcification (MAC), making it a critical diagnostic tool in patients with diabetes or chronic kidney disease where the ankle-brachial index (ABI) may be falsely elevated due to non-compressible vessels.
