BACKGROUND: Wellens' syndrome is known to be associated with left anterior descending artery occlusion that could lead to an extensive anterior wall myocardial infarction. Thus, emergency cardiac catheterization is needed. However, during coronavirus disease 2019 (COVID-19) pandemic, it is recommended for hemodynamically stable acute coronary syndrome patients with COVID-19 infection to be treated conservatively in an isolated hospital ward. CASE PRESENTATION: We report an 85-year-old patient with chief complaints of typical, squeezing chest pain in the past 4 h. The patient had a high fever, dyspnea, sore throat, and fatigue for 3 days. He had previously come into contact with COVID-19 positive relatives. The patient was hemodynamically stable and pulmonary auscultation revealed coarse rales in the entire lung. Electrocardiography (ECG) evaluation during the pain episode showed non-specific ST-T changes in lead V2-V5. After sublingual nitrate was administered, ECG evaluation during the pain-free period revealed a biphasic T wave inversion in lead V2 and V3. Laboratory workup showed elevated cardiac marker and leucopenia with neutrophilia and lymphopenia. Rapid immunochromatographic test and initial severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reverse transcription-polymerase chain reaction (RT-PCR) evaluation from nasopharyngeal swab showed negative results. However, radiographic evaluations suggest the diagnosis of COVID-19 infection. While waiting for the second RT-PCR evaluation, the patient was diagnosed with Wellens' syndrome with suspected COVID-19 infection. The patient was treated conservatively according to national guidelines and scheduled for elective cardiac catheterization. On the third day, the patient felt better and insisted on being discharged home. Ten days after discharged, the patient died of myocardial infarction. CONCLUSION: Emergency cardiac catheterization should be done for patient with Wellens' syndrome, regardless of the COVID-19 infection status.

BACKGROUND: Electrocardiogram (ECG) is a widely accessible diagnostic tool that can easily be obtained on admission and can reduce excessive contact with coronavirus disease 2019 (COVID-19) patients. A systematic review and meta-analysis were performed to evaluate the latest evidence on the association of ECG on admission and the poor outcomes in COVID-19. METHODS: A literature search was conducted on online databases for observational studies evaluating ECG parameters and composite poor outcomes comprising ICU admission, severe illness, and mortality in COVID-19 patients. RESULTS: A total of 2,539 patients from seven studies were included in this analysis. Pooled analysis showed that a longer corrected QT (QTc) interval and more frequent prolonged QTc interval were associated with composite poor outcome ([WMD 6.04 [2.62-9.45], P = .001; I 2:0%] and [RR 1.89 [1.52-2.36], P < .001; I 2:17%], respectively). Patients with poor outcome had a longer QRS duration and a faster heart rate compared with patients with good outcome ([WMD 2.03 [0.20-3.87], P = .030; I 2:46.1%] and [WMD 5.96 [0.96-10.95], P = .019; I 2:55.9%], respectively). The incidence of left bundle branch block (LBBB), premature atrial contraction (PAC), and premature ventricular contraction (PVC) were higher in patients with poor outcome ([RR 2.55 [1.19-5.47], P = .016; I 2:65.9%]; [RR 1.94 [1.32-2.86], P = .001; I 2:62.8%]; and [RR 1.84 [1.075-3.17], P = .026; I 2:70.6%], respectively). T-wave inversion and ST-depression were more frequent in patients with poor outcome ([RR 1.68 [1.31-2.15], P < .001; I 2:14.3%] and [RR 1.61 [1.31-2.00], P < .001; I 2:49.5%], respectively). CONCLUSION: Most ECG abnormalities on admission are significantly associated with an increased composite poor outcome in patients with COVID-19.
