CORRELATION OF INVASIVE AND NON�INVASIVE CENTRAL AORTIC PRESSURES IN PATIENTS UNDERGOING DIAGNOSTIC CORONARY ANGIOGRAM
U. Shobha Jagdish Chandra, M. Padmaja
Abstract :
Central aortic pressure (CAP) is pathophysiologically more relevant than peripheral achial pressure for predicting cardiovascular risk. Recording of CAP can be acquired invasively and non– invasively. Study aim was to compare SphygmoCor® derived non–invasive CAP with invasive CAP. In 50 eligible patients, non–invasive CAP was recorded using applanation tonometry with SphygmoCor and invasive CAP were recorded using Recor pressure Recording system. Mean systolic CAP by non–invasive and invasive techniques were 116.1± 15.18 & 121.04 ± 16.6 mmHg respectively and mean diastolic CAP by non–invasive and invasive techniques were 76.66 ± 9.32 mmHg & 78.14 ± 7.58mmHg respectively. Non–invasive CAP underestimated catheter–measured central systolic pressure by 4.9 mmHg and diastolic pressure by 1.5 mmHg as analysed by Bland–Altman plot. High correlation was observed between non–invasive and invasive systolic and diastolic blood pressures (r = 0.74, r = 0.74 respectively). Non–invasive CAP were found to be in agreement with invasive CAP .
