Echocardiographic Assessment of pulmonary Hypertension in p atients with Heart Diseases Compared with Cardiac
= 5.53, p <0.001. AcT/RVET r = -0.896, SEE = 6.96, p <0.001; b) while positive correlation was found in variables PEP/AcT r = 0.915, SEE = 6.36, p <0.001 and PEP/RVET r = 0.917, SEE = 6.26, p <0.001; c) MPAP obtained by echocardiography (calculated by applying Mahan’s equation) V.S. MPAP obtained by right heart catheterization r = 0.936, SEE = 5.53 mmHg; d) SPAP obtained by echocardiography (calculated by applying Berger’s equation) V.S. SPAP obtained by right heart catheterization r = 0.971, SEE = 5.72 mmHg; e) RVSP obtained by echocardiography (calculated by applying a modified Bernoulli’s equation) V.S. RVSP obtained by right heart catheterization r = 0.882, SEE = 9.399 mmHg; f) RVSP obtained by echocardiography (calculated by applying a modified Bernoulli’s equation) V.S. SPAP obtained by RHC r = 0.972, SEE = 5.60 mmHg. Conclusion: Significant correlation has been found between the haemodynamic parameters obtained by noninvasive echocardiographic examination and those obtained by right heart catheterization.
