Abstract

Introduction: Information of cardiac left ventricular (LV) blood pressure (BP) is importance in noninvasive evaluating LV wall stress. Our aim from this study is to evaluate whether it is possible to assess LVBP from radial artery BP information in patients suffering from coronary artery atherosclerosis and the normal.Method: A total of 74 patients with significant and moderate left coronary artery disease (LAD) stenosis and 32 patients with normal coronary artery aged between from 40 to 60 years were included in the study. LVBP measured directly by a pressure sensor and then selective catheterization of the right and left coronary arteries with contrast injection was performed in a conventional manner and determined the intensity of coronary stenosis. Radial artery BP was measured with a calibrated oscilometric device (Microlife, BP 3BU1-5) simultaneously.Results: Mean systolic and diastolic radial artery and LV BP were 136.9±13.6/81.0±11.5 mmHg and 132.2±12.9/7.9±2.9 mmHg respectively. Regression equation and Pearson correlation coefficient calculated for all above mentioned groups separately and additively. Pearson correlation coefficient was at least 0.85 for each group.Conclusion: We found that there existed significant correlation between radial arterial and LV systolic BP for significant, moderate stenosis and normal therefore can be expected to be developed into mathematical transformation equations for noninvasive assessment of LVBP. The results of this study can be use for noninvasive assessment of LV wall stress.
