A CASE REPORT ON SINGLE-VESSEL CORONARY ARTERY DISEASE DETECTED WITH A SMARTPHONE-BASED ECG DEVICE.

Background: The electrocardiogram (ECG) is the only easily accessible diagnostic procedure for a patient with chest pain who is suspected of having acute coronary syndrome (ACS). Case Presentation: We describe a case of a 45-year-old woman with a known history of type 2 diabetes mellitus, who presented with complaints of acute chest pain at a cardiac care unit. Based on the presenting complaints, a gold standard 12-lead ECG (Philips PageWriter ECG) was performed, which showed ST-elevation in leads V1 to V6, suggestive of anterolateral myocardial infarction. She had a smartphone-based ECG the following day, utilising a Spandan smartphone-based ECG device, which showed inversion of the T wave in lead I and J-point elevation in V1 to V6 along with ST-elevation in V3 to V6, II, III, and AVF. These findings were suggestive of inferior STEMI and anteroseptal MI. On the same day, coronary angiography showed a 90% blockage of the left anterior descending (LAD) artery with grade II thrombus and a 60% ostial lesion of the right coronary artery (RCA), suggestive of single-vessel disease of the LAD artery. Conclusion: This case study highlights the diagnostic utility of a Spandan smartphone-based ECG device in detecting ECG abnormalities indicative of single-vessel CAD, which was later confirmed by a report of coronary angiography.
