Ventricular Diastolic Dysfunction

Background: The frequency of left ventricular diastolic dysfunction (DD) is overestimated by earlier recommendations. We compared the 2009 and 2016 guidelines regarding the detection of DD and explored the potential of adding left atrial (LA) strain to the current guideline. Methods: Consecutive patients with heart failure were enrolled. All the patients were examined using 2-dimensional speckle-tracking echocardiography (2D-STE) and tissue Doppler imaging. DD was evaluated in terms of E/eʹ, eʹ velocity, E, A, tricuspid regurgitation velocity, LA volume, and LA strain. Results: This study evaluated 147 patients (101 males, 68.7%) at a mean age of 54.73±14.42 years. LA strain decreased with increasing grades of DD in both guidelines. The rate of reclassification between the 2 guidelines was 41%. The detection rate of normal diastolic function increased after the implementation of the 2016 guideline. LA strain discriminated individuals with normal diastolic function from those with DD more accurately than did LA volume index (area under the curve [AUC] =0.816 vs AUC=0.759, respectively). When LA strain <23% was incorporated into the 2016 guideline, 2 out of 4 patients with indeterminate diastolic function were reclassified as normal and 2 patients as grade I DD. The rate of reclassification was 4.1% after the addition of LA strain to the current guideline (κ=0.939, P<0.001). Conclusion: This study showed that the current guideline detected lower rates of DD than did the earlier recommendations. Furthermore, the incorporation of LA strain into the current guideline resulted in lower rates of indeterminate diastolic function.

Abstract Background Left atrial strain in the reservoir phase (LASr) measures passive LA stretch and is a sensitive marker of left ventricular diastolic dysfunction (DD). However, reduced LASr has not been prospectively validated against clinical heart failure (HF) endpoints and its place in diastology evaluation is unclear. Aim We sought whether DD grades defined by previously validated ranges of LASr predicted incident HF and whether reclassifying indeterminate diastolic function based on reduced LASr could facilitate assessment of HF risk. Methods Community dwelling elderly subjects were recruited and underwent baseline clinical and echocardiographic assessment. Where imaging was suitable, speckle-tracking echocardiography assessed LASr and subjects were assigned DD grades based on published ranges: normal >35%, grade 1 24–35%, grade 2 19–24%, grade 3 <19%. Current ASE/EACVI recommendations were used to identify those with indeterminate function; LASr-defined DD (LASr-DD) was defined as LASr ≤23%. Follow-up was ≤2 years and incident HF adjudicated by Framingham criteria. Results Of 610 subjects (age 71±5 yrs., 46% male) LASr analysis was feasible in 590 (97%); average LASr was 39% (IQR 34–43%). Incident HF was associated with LASr-DD grade, occurring in 8 (36%) with grade ≥2, 14 (10%) with grade 1 and 39 (9%) with normal function (p<0.001). Adjusted odds ratio for incident HF for LASr-DD grade ≥2 was 3.12 (95% CI 1.06–9.1, p=0.038) Diastolic function was indeterminate in 147 (24%) subjects; of 144 (98%) with LAS analysis, 6 (75%) of those with LASr-DD vs. 15 (11%) with normal LASr experienced incident HF (p<0.001). Univariable Multivariable* OR (95% CI) p-value OR (95% CI) p-value LASr-DD grade:   1 1.13 (0.59–2.15) 0.7 0.84 (0.42–1.69) 0.63   ≥2 5.7 (2.26–14.5) <0.001 3.12 (1.06–9.1) 0.038 *Adjusted for age, hypertension, diabetes, BMI, global longitudinal strain, E/e', LA volume index, LV mass index (all p<0.1 on univariable analysis). Incorporating LA strain in practice Conclusion DD defined by LASr is predictive of HF for grades ≥2 independent of other diastolic measures. Indeterminate diastolic function with LASr ≤23% is associated with incident HF. LASr may complement current diastolic function assessment recommendations.

Ventricular Diastolic Dysfunction

Background: Diastolic dysfunction as part of heart failure with preserved ejection fraction (HFpEF) has gain interests, due to the increasing prevalence rate and poor prognosis. Besides the mechanism is not fully understood, there are some difficulties in detecting the presence of diastolic dysfunction. Previous studies have shown correlation between some electrocardiographic parameters and diastolic function. Furthermore, the aim of this study is to assess the diagnostic value of the QTc interval in detecting left ventricular diastolic dysfunction.Methods: A cross sectional study was conducted on patients with clinical suspicion of heart failure. Electrocardiographic examination was performed to obtain QTc interval (msec) using the Bazett formula. Left ventricular diastolic function was assessed using Tissue Doppler Imaging by echocardiography. Using correlation test and ROC method, the relationships between QTc interval and LV diastolic function were investigated.Results: Of 82 patients analyzed, there were 62 patients (75.9%) known to have diastolic dysfunction. The QTc interval was found to be longer in the group with diastolic dysfunction compared to the normal group (442.9±27 vs. 402.1±18.2, p <0.001). There was a strong negative correlation between the QTc interval and diastolic function (r = -0.619; p <0.001). Using ROC analysis, the cut off point for QTc interval was 410 ms with 91% sensitivity, 70% specificity, and 90% positive predictive value.Conclusion: The QTc interval is an accurate, simple and highly feasible electrocardiographic parameter as a screening tool to determine the presence of left ventricular diastolic dysfunction.
