Effect of Systemic Arterial Blood Pressure on Fractional Flow Reserve
Author(s): Osman Kayapinar*
Backgraund: Fractional flow reserve (FFR) measures the flow reserve of narrowed coronary arteries. It is calculated simply as the ratio of
hyperemic distal coronary pressure (Pd) to aortic pressure (Pa) (Pd/Pa). We aimed to examine the relationship between arterial blood pressure
normalization and FFR in hypertensive patients.
Methods: Twenty patients (14 males, 6 females; age 62.7±6.1 years) who underwent coronary angiography (CAG) with a diagnosis of stable
coronary artery disease (CAD), and had 50–70% stenosis in their coronary arteries and a blood pressure higher than 140/90 mmHg in the catheter
laboratory, were included in this study. The total number of lesions studied was 20. FFR was measured using a pressure measurement wire from
Certus (St. Jude Medical, St. Paul, MN, USA). Measurements were made with 150 m.. Read More»
