Project description:De Winter electrocardiograph (ECG) pattern is an atypical presentation of acute myocardial infarction (AMI) due to severe stenosis of the left anterior descending (LAD). Complications of acute aortic dissection (AD) in the setting of acute myocardial infarction (AMI) with de Winter sign are relatively rare and physicians may easily miss the diagnosis of AD. We report a case of patient with acute chest pain and de Winter ECG pattern due to AD involving the left main coronary artery (LM), LAD and left circumflex artery (LCX). A 57-year-old male patient was initially diagnosed with AMI and then the diagnosis of acute AD was supported by transthoracic echocardiograph (TTE). After two stents were implanted respectively into the proximal LM-LAD and LM-LCX, he recovered from cardiogenic shock. Two months later, the patient underwent the surgery of ascending aorta replacement. After the surgery, there was no obvious chest discomfort during follow-up. When an ECG shows a "de Winter pattern", we should also consider the possibility of AD which result in LAD occlusion. TTE is a useful tool in screening for AD. Further research is needed to prove that percutaneous coronary intervention (PCI) may be a useful treatment strategy in the case of AD leading to severe LAD occlusion and unstable hemodynamics when there's no condition to perform aortic replacement surgery immediately.

Project description:BackgroundThe 12-lead electrocardiogram (ECG) remains the primary test for diagnosis of acute myocardial infarction (MI) secondary to acute coronary occlusion or near occlusion, with insufficient collateral circulation. Decisions regarding urgent reperfusion are based on whether or not there's new ST-segment elevation. The de Winter ECG pattern is a distinct ECG pattern without any ST-segment elevation, it may be missed by anyone unfamiliar with it.Case summaryWe present a case whose chief complaint was severe central chest pain, the patient was diagnosed with acute MI secondary to a culprit lesion in the left anterior descending artery, despite the ECG not meeting standard STEMI criteria. After the ECG's significance was recognized by paramedics, the patient received immediate percutaneous coronary intervention with stenting and was discharged home after a brief hospital admission.DiscussionIn some cases, acute MI presents with ECG features that do not meet the standard criteria for STEMI diagnosis. The de Winter ECG pattern is one such example. This pattern should be immediately recognizable to those responsible for the activation of the catheterization laboratory, physicians, and paramedics included.

Project description:Background:A 'STEMI equivalent' electrocardiogram (ECG) pattern reflects an acute thrombotic occlusion of a large epicardial coronary artery without ST-segment elevation. These ECG patterns are less known by caregivers. Case summary:We describe the case of a 56-year-old patient suffering from acute chest pain, presenting in our emergency department with a 'de Winter' ECG pattern: an upsloping ST-segment depression with tall symmetrical T waves associated with left anterior descending artery occlusion. Discussion:The 'de Winter' ECG pattern, as other 'STEMI equivalent', must be recognized promptly and treated as soon as possible with emergent reperfusion by percutaneous coronary intervention.

Project description:BackgroundDe Winter syndrome accounts for approximately 2% of all patients with acute anterior myocardial infarction admitted to the emergency department, and is characterized by severe stenosis of the left anterior descending coronary artery (LAD). The ECG changes are not recognized by ECG software, and poor understanding of the syndrome among physicians may lead to misdiagnosis, delayed reperfusion, and mortality.Case presentationA 51-year-old male patient presented with a newly developed ECG pattern suggestive of de Winter Syndrome. Coronary angiography revealed anterior myocardial infarction. Based on the ECG and clinical manifestations, the patient was diagnosed with de Winter syndrome and underwent timely percutaneous coronary intervention to revascularize the left anterior descending artery (LAD). The patient showed good outcomes and no complications at 4 months after the operation.ConclusionsThis case highlights the importance of being aware of the possibility of de Winter syndrome in patients with symptoms of myocardial infarction but atypical ECG in order to conduct early revascularization and treatments.

Project description:The de Winter electrocardiographic (ECG) pattern was characterized by upsloping ST-segment depressions, tall and positive symmetrical T waves in precordial leads. This rare ECG pattern was recognized as an indication of proximal left anterior descending artery occlusion. Less commonly, this ECG pattern was reported in association with occlusion of other coronary artery segments. We present three cases of the de Winter pattern associated with acute total left main occlusion. This pattern may evolve to ST elevation within hours of presentation. Widespread upsloping ST-segment depressions from V2 -V6 , centered on V5 were observed in these patients.

Project description:Background: Both acute pancreatitis and acute myocardial infarction (AMI) are rapidly progressive and frequently fatal diseases that can be interrelated and lead to a vicious cycle for further problems. The concomitant occurrence of AMI and acute pancreatitis is rare but critical, and efficient diagnosis and treatment of such patients are challenging. Case Summary: We reported an uncommon case of abnormal ECG findings in a 63-year-old woman with acute pancreatitis. The patient exhibited increased biomarkers of myocardial injury, such as creatine kinase-MB (CK-MB) and troponin T, as well as ST segment elevation in inferior leads II, III, and aVF. Both of these have been previously observed in patients with acute abdomen in the absence of ST-segment elevation myocardial infarction (STEMI), including pancreatitis. In addition, lacking complaints of chest pain or tightness was also supportive of this idea. Echocardiography indicated abnormalities in the functioning of the left inferior posterior wall segments and decreased overall systolic function of the left ventricle with a 51% ejection fraction. Eventually, AMI was diagnosed after coronary computed tomography angiography (CCTA) showing critical stenosis of the right coronary artery and left anterior descending artery segments. The patient was urgently transferred to intensive care unit and was treated with anticoagulation, antiplatelet aggregation, lipid-lowering and other palliative drugs. Conclusion: Concomitant acute pancreatitis and AMI are often considered to be critical conditions with a poor prognosis. Therefore, it is important to rapidly identify this condition and consider transferring patients for multidisciplinary supportive care.

Project description:Takotsubo syndrome usually occurs immediately following a physical or emotional trigger. In some cases, a triggering stress may not be evident. A delayed manifestation of the syndrome may account for such cases. An asymptomatic 69-year-old woman presented for a routine cardiac check-up, which revealed normal electrocardiogram (ECG), echocardiography, and exercise ECG. She did not complain of any chest pain during or immediately after the tests. After about 24 h, she developed chest pain for which she was admitted with the provisional diagnosis of acute coronary syndrome. ECG showed dynamic T-wave changes with QTc prolongation. Cardiac biomarkers were mildly elevated. Characteristic reversible left ventricular dysfunction in absence of coronary stenosis ultimately led to the diagnosis of Takotsubo syndrome. Our case represents a delayed occurrence of Takotsubo syndrome triggered by a treadmill exercise stress test, which manifested about 24 h following the stressor. Such delayed manifestation may account for those cases of Takotsubo syndrome where no immediate triggering stressor is evident.

Project description:BackgroundThyroid storm is a rare condition with well-known cardiovascular manifestations including tachycardia, atrial fibrillation, heart failure, and myocardial infarction (MI). Several uncommon conditions that can mimic MI are associated with thyrotoxicosis and discussed in this case.Case summaryA 23-year-old previously healthy male presented after the onset of generalized weakness and inability to rise from bed in the setting of 35 kg of unintentional weight loss, and was found to have profound hypokalaemia, elevated thyroid hormone, and suppressed thyroid-stimulating hormone consistent with thyrotoxicosis secondary to Grave's disease. Following hospital admission, he developed worsening tachycardia with dynamic anteroseptal ST-segment elevations and elevated cardiac biomarkers concerning for MI. He was treated with aspirin, ticagrelor, and a heparin infusion, but was unable to tolerate beta-blockade acutely due to hypotension. Echocardiography demonstrated a severely dilated left ventricle (left ventricular end-diastolic volume index 114 mL/m2) and severely reduced systolic function (ejection fraction 23%) with global hypokinesis. Following initiation of propylthiouracil, iodine solution, and stress-dosed steroids his tachycardia and ST-elevations resolved. Computed tomography (CT) coronary angiography demonstrated no evidence of coronary stenosis. He was discharged on methimazole, metoprolol, and lisinopril and found to have recovered left ventricular systolic function at 2-month follow-up.DiscussionThyrotoxicosis can rarely cause coronary vasospasm, stress cardiomyopathy, and autoimmune myocarditis. These conditions should be suspected in hyperthyroid patients with features of MI and normal coronary arteries. Workup should include laboratory evaluation, electrocardiography (ECG), echocardiography, and non-invasive or invasive ischaemic evaluation.

Project description:BackgroundThe de Winter's electrocardiogram (ECG) pattern signifying proximal left anterior descending (LAD) artery occlusion was first described in 2008. The ECG changes were thought to be static and mechanisms for this were suggested. In addition, the optimal management of these patients was reported to be via a primary percutaneous coronary intervention (PCI) strategy.Case summaryCase 1: A 48-year-old gentleman presented with a 2-h history of ischaemic chest pain with initial de Winter's pattern on ECG. This progressed to anterior ST-elevation myocardial infarction (STEMI) complicated by ventricular fibrillation. Emergency angiography revealed a mid-vessel LAD occlusion which was successfully reperfused. Case 2: A 34-year-old female presented with a 2-h history of ischaemic chest pain with initial ECG showing a de Winter's pattern. Due to concerns of performing PCI timeously, a pharmacoinvasive strategy of reperfusion was adopted with resolution of the de Winter's pattern. Urgent angiography revealed a proximal LAD lesion which was successfully stented.DiscussionThe two cases highlight that the de Winter's pattern may in fact not be static, but rather lie along the continuum of ischaemia and may evolve into STEMI. In addition, we provide further evidence that if primary PCI cannot be offered in a timeous manner, thrombolytic therapy may be considered in such patients. The de Winter's pattern remains a high-risk ECG pattern that requires early recognition and intervention.
