Correlación y concordancia entre ecocardiografía y cateterismo cardiaco derecho para determinación de la presión sistólica de arteria pulmonar

Abstract

Introduction: Right heart catheterism represents the standard of reference to the diagnosis of pulmonary hypertension.Nevertheless the yield of echocardiography as initial study has showedgood correlation with some measures estimated in catheterism. This study tries to describe the level of correlation and concordance between echocardiography and Right heart catheterism to systolic pulmonary arterial pressure measurement. Materials and methods: A retrospective observational study was conducted to patients who underwentright heart catheterism between years 2009 to 2014 and they were compared with echocardiography data time interval shorest to the catheterism, taking into account systolic pulmonary arterial pressure (PASP) measurement through correlation and concordance between two diagnostic tests, we calculated the Pearson and Lin coefficient respectively. Results: we collect 169 patients with a Pearson correlation coefficient of 0.73 p < 0.0001 obtained to systolic pulmonary arterial pressure (PASP) measurement in whole of the sample, showing high correlation. Concordance analysis withLin coefficient was 0.71 that means little concordance. Discussion: There was a good correlation between echocardiography and Right heart catheterism for systolic pulmonary arterial pressure (PASP) measurement, nevertheless concordance between twodiagnostic methods is poor, therefore echocardiography does not replace right heart catheterism for pulmonary hypertension diagnosis and monitoring.
