Koroner Arter Hastalarında Sol Ventrikül Kontraksiyonunu Değerlendirmede Basınç-Volüm Oranlarının Ejeksiyon Fraksiyonuna Kıyasla Duyarlılığı
Abstract
This study compares the sensitivity of end-systolic pressure-volume (ESP/ESV) and peak systolic pressure-volume (PSP/ESV) ratios to ejection fraction (EF) in evaluating left ventricular contraction in patients with coronary artery disease. Data from normal subjects and two patient groups—those with normal ventricular wall motion and those with segmental wall motion abnormalities—were analyzed statistically. Findings indicate that pressure-volume ratios are more responsive to contraction changes than EF, especially in patients with wall motion abnormalities. The study suggests that these ratios may serve as more effective indices for clinical evaluation and monitoring.
