Key result
Left and right ventricular myocardial performance indices significantly correlated with pulmonary artery pressure in patients with mitral stenosis (r=0.65 and r=0.63, respectively; P<0.001).
Why the study?
Does myocardial performance index (MPI) correlate with pulmonary artery pressure (PAP) in patients with mitral stenosis?
Cross-Sectional (n=86)
Does myocardial performance index (MPI) correlate with pulmonary artery pressure (PAP) in patients with mitral stenosis?
Effect estimate: r = 0.65
p-value: p=<0.001
Left and right ventricular myocardial performance index obtained by tissue Doppler imaging are important markers that correlate with pulmonary artery pressure in patients with mitral stenosis.
No takes yet. Share an insight, caveat, or question.
MPI may support noninvasive PAP estimation in mitral stenosis; hypothesis-generating and should not yet change practice.
Özdemir et al. (2003) conducted a cross-sectional in Mitral Stenosis (n=86). Myocardial performance index (MPI) vs. Healthy controls was evaluated on Correlation of pulmonary artery pressure (PAP) with left and right ventricular MPI (r = 0.65, p=<0.001). Left and right ventricular myocardial performance indices significantly correlated with pulmonary artery pressure in patients with mitral stenosis (r=0.65 and r=0.63, respectively; P<0.001).
