Gated SPECT Abnormality With J Point Elevation
The Unidentified Association of Gated SPECT Abnormality With J Point Elevation
Study Overview
Status
Detailed Description
The isolated J-point elevation considered as a type of "early repolarization" pattern (ER), is commonly been regarded as a benign finding. However, ER associations with arrhythmic sudden death from CAD or sudden cardiac death due to either idiopathic ventricular fibrillation have been shown. A recent study reported that ER especially in inferior leads, was related to worse cardiac outcomes in patients with CAD and they argue that ER in patients with CAD seems to be associated with the myocardial scar in the absence of pathologic Q waves.
Likewise, it is rare to detect clinically important gated SPECT abnormalities in normal myocardial perfusion studies with normal transient ischemic dilatation (TID) score and without any right ventricular uptake or any pulmonary uptake. Normal myocardial perfusion findings with wall motion abnormalities are frequently encountered in the interventricular septum of the patients who have previous bypass surgery or in patients with left bundle branch block (LBBB). However, the presented patient did not have the history of any intervention or LBBB. Perfusion and function discordance can be encountered in non-ischemic dilated cardiomyopathy patients; nonetheless, EF is markedly reduced in these patients.
The presented case, J point elevation in the ECG associated with relative wall motion abnormality was an important clue to determine CAD in the lack of evident perfusion defects or significant ECG findings.
The presence of wall motion abnormalities during stress study to predict CAD in patients with normal perfusion pattern, owing to balanced ischemia, was not only reported in multi-vessel disease but also in single-vessel disease without having presented the association between either regional wall motion abnormality or a localized particular ECG pattern and culprit lesion territory.
The interesting part of the presented case is, notwithstanding the myocardial perfusion pattern is normal, the abnormal gated finding with ECG changes having the concordant localization can be a significant milestone on the way to the diagnosis. To the best of investigators knowledge, the association between J point elevation and wall motion abnormality have not been described yet. Therefore, the investigators would like to draw attention to the importance of adjoining trivial ECG changes and wall motion abnormality for readers anymore.
