Background: Predicting of coronary artery disease (CAD) severity and percutaneous coronary intervention (PCI) outcomes is important to improve health and longevity. Blood pressure (BP) phenotype recognition is simple and can be easily done. So using it for percutaneous coronary intervention outcome prediction is crucial and promising.

Aim: To assess coronary angiographic findings and PCI outcomes in relation to different hypertension phenotypes.

Methods: This observational study included 105 participants diagnosed with coronary artery disease and were planned for PCI. The 24h ambulatory blood pressure monitoring was performed to all patients. Patients were categorized into three groups based on the observed phenotypes of hypertension; 26 patients (24.76%) were classified as white-coat hypertension group, 42 patients (40%) as masked hypertension group and 37 patients (35.42%) as sustained hypertension group.

Results: There was no statistical significant difference between the three studied groups regarding to number of diseased coronaries, SYNTAX score, mortality and non-fatal MI.

Conclusion: ABPM for targeting WCHT and MHT is crucial, as they are not less than SHT regarding coronary artery disease severity and percutaneous coronary intervention outcome.
