Relationship Between the Progression of Coronary Artery Disease and Pulse Pressure Index: A Cross-Sectional Work.

This study sought to analyze the relationship between pulse pressure (PP) index (PPI) (PP/systolic blood pressure; a less variable and objective form of PP) and coronary artery disease (CAD) progression. A registry of 193 patients was evaluated to show CAD progression by comparing current vs previous (6 months to 3 years prior) angiograms. One day after the second angiogram, we conducted ambulatory blood pressure measurements on the patients. Of the 193 patients, 65 (34%) had CAD progression. The PP and PPI were significantly higher in the progression than in the non-progression group (55 ± 12 vs. 51 ± 10 mmHg,
