Left ventricular diastolic dysfunction was associated with a significantly higher mitral inflow E-wave acceleration rate (1364.38 vs 859.12) compared to normal diastolic function (P=0.0001).
Cross-Sectional
Yes
Does transmitral Doppler acceleration rate and time correlate with left ventricular diastolic dysfunction?
Transmitral Doppler acceleration time and rate correlate significantly with diastolic dysfunction in patients with normal ejection fraction, though they do not relate to the grading of diastolic dysfunction.
Absolute Event Rate: 1364.38% vs 859.12%
p-value: p=0.0001
Background: Diastolic dysfunction (DD) has a high prevalence in the community. Although it often remains asymptomatic, it can be a significant cause of morbidity and mortality. The assessment of the left ventricular diastolic function (DF) should be an integral part of a routine examination, particularly in patients presenting with dyspnea or heart failure. Patients and Methods: A cross-sectional study started from June 2018 to February 2019. The study was conducted in four medical institutions in Baghdad. Mitral inflow for the assessment of left ventricular DF depending on guideline 2016 was performed. Results: Left ventricular ejection fraction (EF) was higher in a group with normal DF than in the group with DD ( P = 0.0001). Mean E/A ratio was higher among patients 2.15 ± 0.48 than in the control Group 1.30 ± 0.50 the difference between them was significant ( P = 0.0001). Mean acceleration time (AT) was longer in individual with normal DF (88.23 ± 13.85) than that of patients with LVDD (72.89 ± 8.88), while the acceleration rate in LVDD group (1364.38 ± 277.31) was higher than that in normal LVDF (859.12 ± 275.95). There was a significant difference ( P = 0.0001) between the two groups. Conclusion: AT and rate were significantly correlated with DD in normal EF group, but both of them have no relation to the grading of DD.
Alsalman et al. (Fri,) conducted a cross-sectional in Diastolic dysfunction. Left ventricular diastolic dysfunction vs. Normal diastolic function was evaluated on Mitral inflow E-wave acceleration rate (p=0.0001). Left ventricular diastolic dysfunction was associated with a significantly higher mitral inflow E-wave acceleration rate (1364.38 vs 859.12) compared to normal diastolic function (P=0.0001).
