Subjects and methods This descriptive prospective cross sectional study was conducted from August 2022 to June 2023 among 254 patients who were divided into two groups: a group of patients with left ventricular diastolic dysfunction and a group without left ventricular diastolic dysfunction, diagnosed with significant coronary microvascular syndrome (stenosis ≥ 50%) on transdermal coronary angiography and underwent echocardiography at the Vietnam Heart Institute. Results: The diagnosis of left ventricular diastolic dysfunction using the PTF-V1 threshold with a threshold of >
3.5 mV.ms had a sensitivity of 83.3%, specificity of 68.0%, and AUC of 0.76
using the Tend-P threshold of <
=280 ms had a sensitivity of 79.3%, specificity of 63.5%, and AUC of 0.754
using the Tend-Q threshold of <
=360 ms had a sensitivity of 64.8%, specificity of 80.0%, and AUC of 0.792
when combined with other factors, the diagnostic value of left ventricular diastolic dysfunction using the Tend-Q/ (PQ x age) index with a threshold of <
=0.03 had a sensitivity of 75.9% and specificity of 72.0%, with an AUC of 0.782. Conclusions: On the electrocardiogram, the Tend-Q (ms) index and the Tend-Q/ (PQ x age) index are shown to be the most valuable indices in predicting the presence of left ventricular diastolic dysfunction.
