“… Prevalence and prognosis of isolated posterior ST-segment elevation acute myocardial infarction using synthesized-V7–9 lead Shimojo et al . 2021 [ 16 ] 10 patients Among 142 consecutive patients with STEMI with the culprit lesion on LCx, 10 patients (7.0%) had ST elevation only in synthesized V7–V9 lead who classified as STEMI-LCx-synV7–V9 group and the remaining as STEMI-LCx-12ECG group [132 patients (93%)] The patients with STEMI-LCx-synV7–V9 had significantly higher incidences of cardiac death within 3 months and 1 year (30.0% versus 6.1%, p = 0.031, 30.0% versus 7.6%, p = 0.050, respectively) and mechanical complications in each follow-up period (20.0% versus 1.5 %, p = 0.025) than those with STEMI-LCx-12ECG …”

Indeed, IPMI has been widely discussed in previous studies, including the importance of posterior lead ECG [6,[11][12][13][14][15][16].

Background True isolated posterior myocardial infarction is an uncommon finding of acute coronary syndrome, with an incidence rate of 3–7%. The prevalence rates of isolated posterior myocardial infarction in men and women are 72% and 28%, respectively. This uncommon finding may be attributed to multiple factors, such as unremarkable changes on 12-lead electrocardiography, a lack of awareness or knowledge, and an absence of diagnostic consensus, which leads to reperfusion delay and poor clinical outcomes. Case summary Herein, we report three cases of acute myocardial infarction presenting as isolated ST-segment elevation in the posterior leads (V7–V9): Asian men aged 57, 62, and 53 years, who presented with ST-segment depression in V1–V3 that resolved gradually. Coronary angiography revealed a total/critical occlusion of the proximal circumflex coronary artery in all three cases. Routine and accurate interpretations of 15-lead electrocardiography (12-lead with additional V7–V9) resulted in a better sensitivity for isolated posterior myocardial infarction diagnoses, followed by a timely and opportune primary percutaneous coronary intervention. Conclusions Isolated posterior myocardial infarction is a rare but potentially fatal event that is often accompanied by atypical and subtle changes on 12-lead electrocardiography (especially in the V1–V3 precordial leads) and may remain undetected by physicians. Therefore, the comprehensive and routine application of posterior leads is a crucial addition to the standard diagnosis and management of acute coronary syndrome in patients with subtle ST-segment changes who do not fulfill the criteria for ST-elevation myocardial infarction.

Since patients with occlusive coronary artery thrombosis benefit more from emergency reperfusion, after the widespread introduction of thrombolytic therapy, the concept of Q-wave and non-Q-wave myocardial infarction was replaced by the concept of ST-segment elevation (STE) and non-STE (NSTE) acute coronary syndrome (ACS). But at present, due to the spread of mechanical reperfusion, this concept does not seem to be fully perfect. The electrocardiographic (ECG) diagnostic method allows, among patients with NSTE-ACS, to identify a group of patients with occlusive and/or prognostically unfavorable hemodynamically significant coronary lesions, as well as to provide them with timely percutaneous coronary intervention as early as possible and to improve outcomes. This article rationales changing approaches to the management of patients with NSTE-ACS and analyzes in detail the currently known ECG criteria for occlusive and/or prognostically unfavorable coronary lesions.
