The authors describe a case of suspected ST-segment elevation myocardial infarction (STEMI) based on isolated ST elevation in lead V2, subtle ST elevation in leads I and aVL, and reciprocal changes in lead III, ultimately attributed to occlusion of the first diagonal (D1) branch of the left anterior descending artery.</p><p>Although we commend the authors for highlighting this important and often underrecognized electrocardiographic pattern, we respectfully propose an alternative interpretation of the initial ECG. Upon close inspection, lead V2 does not demonstrate classic ST-segment elevation. Instead, it exhibits upsloping ST-segment depression followed by a tall, symmetric T wave, a morphology consistent with the de Winter pattern. Leads I and aVL similarly show hyperacute T waves without definitive ST elevation, suggesting early transmural ischemia rather than established injury current.</p><p>The de Winter pattern, originally described in proximal LAD occlusion, is increasingly recognized in isolated D1 occlusion, particularly when the ischemic vector is postero-inferiorly, aligning with the axis of lead V2 (de Winter et al. <span>2008</span>). This pattern represents a STEMI equivalent, often preceding overt ST elevation, and mandates urgent reperfusion therapy.</p><p>This single-lead V2 de Winter pattern is, to my knowledge, previously unreported and may represent the earliest electrocardiographic signature of a proximally arising, anatomically dominant D1 branch. Recognition of isolated de Winter morphology in V2 as a solitary anterior lead sign of D1 occlusion is clinically invaluable, especially in the absence of contiguous lead involvement. It expands the spectrum of occlusion myocardial infarction (OMI) patterns and supports the shift from traditional STEMI versus NSTEMI paradigms toward OMI versus NOMI classification (McLaren et al. <span>2024</span>).</p><p>We congratulate the authors on this insightful case and emphasize that hyperacute T waves and de Winter morphology, even in a single lead, should prompt immediate suspicion of coronary occlusion and urgent angiographic evaluation.</p><p>The author takes full responsibility for this article.</p><p>The author declares no conflicts of interest.</p>","PeriodicalId":8074,"journal":{"name":"Annals of Noninvasive Electrocardiology","volume":"30 5","pages":""},"PeriodicalIF":1.1,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/anec.70115","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145136009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Interpreting Alcohol-CV Associations in AF Requires Scrutiny of Drinking Behaviors and Socioeconomic Context","authors":"Yuren Cao","doi":"10.1111/anec.70106","DOIUrl":"https://doi.org/10.1111/anec.70106","url":null,"abstract":"&lt;p&gt;We read with great interest the article by Oraii and colleagues (Oraii et al. &lt;span&gt;2025&lt;/span&gt;). Utilizing a large international cohort (the RE-LY AF registry), the study provides novel insights into the association between different levels of alcohol consumption and cardiovascular outcomes (stroke/systemic embolism, heart failure [HF] hospitalization, major bleeding) in patients with atrial fibrillation (AF). However, when interpreting these important findings, we believe there are noteworthy methodological limitations that warrant attention and improvement in future research.&lt;/p&gt;&lt;p&gt;The study's simplification of alcohol intake to weekly averages, without distinguishing drinking patterns or beverage types, may substantially impact the reliability of its conclusions. Of particular concern is that the concealed risk of binge drinking (≥ 5 drinks per occasion) is obscured by the weekly average grouping. Robust evidence indicates that binge drinking can acutely elevate blood pressure, trigger AF episodes, and promote platelet aggregation, independently increasing stroke risk by approximately 35% (Pooled RR = 1.35) (O'Donnell et al. &lt;span&gt;2010&lt;/span&gt;; Degerud et al. &lt;span&gt;2021&lt;/span&gt;). The “heavy drinker” group (≥ 14 drinks/week) in this study likely included a significant proportion of such high-risk individuals engaging in binge patterns, yet showed only a non-significant reduction in stroke risk (aOR = 0.79). Isolating a binge drinking subgroup might reveal significantly elevated stroke and bleeding risks, especially in the context of anticoagulant therapy, potentially reversing the neutral conclusion that alcohol does not increase thrombotic risk. Concurrently, the confounding effect of beverage type was uncontrolled. The potential cardioprotective effects of polyphenols in wine might dilute the overall observed risk, while a predominance of spirits could amplify harm—this heterogeneity introduces bias into the interpretation of dose–response relationships (Castaldo et al. &lt;span&gt;2019&lt;/span&gt;). While this limitation has a lesser impact on the conclusion regarding HF protection (as chronic benefits may align more with regular, moderate consumption), it likely leads to a systematic underestimation of stroke and bleeding risks, diminishing the study's value for clinical decision-making. Future research urgently needs to integrate dimensions of drinking pattern and beverage type into alcohol categorization; failure to do so risks misleading safety advice for high-risk populations like binge drinkers.&lt;/p&gt;&lt;p&gt;Stratifying the alcohol-heart failure association solely by country income, without adjusting for socioeconomic status (SES), healthcare access, or lifestyle factors, fundamentally weakens the conclusion (Allen et al. &lt;span&gt;2018&lt;/span&gt;). The apparent “protective effect” in high-income countries (aOR = 0.51) likely reflects superior healthcare (e.g., early intervention) and healthier behaviors in high-SES populations, not alcohol itself.
