Before surgery, patients in both groups were given conventional treatments such as coronary expansion, antiplatelet, anticoagulati...

To the Editor In their report of an inferior and anterior myocardial infarction (MI) owing to an occluded wraparound left anterior descending coronary artery (LAD), Kapil and colleagues attribute the ST depression seen in lead V2 to a reciprocal change owing to inferior wall involvement by the wraparound vessel. However, whereas leads I and especially aVL will typically manifest reciprocal ST depressions in inferior wall STEMI, this is not the case with lead V2 unless there is involvement of the posterior wall. Furthermore, the structure of the ST segment in V2 is not consistent with reciprocal change in this case where th...

In Reply We thank Drs Rubin and Montana for their comments on our Challenges in Clinical Electrocardiography. They assert that the ST-segment depression in V2 is unlikely to be a reciprocal change to inferior wall ST-segment elevation, and more likely to represent an evolving de Winter pattern of hyperacute T waves in acute anterior myocardial infarction. While we somewhat agree with the authors, in the original description of de Winter pattern the ST-segment showed a 1- to 3-mm upsloping ST-segment depression at the J point in all precordial leads V1 to V6 with tall positive and symmetrical T waves. The electrocardiogram ...

There is a scarcity of data on ischemic and bleeding events in patients who experienced major bleeding after percutaneous coronary intervention (PCI). Moreover, there also is a shortage of data on comparative outcomes between patients with and without interruption of an antithrombotic drug after major bleeding. We evaluated the incidence and prognostic impacts of ischemic (myocardial infarction or ischemic stroke) and bleeding (Bleeding Academic Research Consortium type 3 or 5) events after major bleeding in 12,691 consecutive patients who underwent first PCI in the Coronary Revascularization Demonstrating Outcome Study in...

Online ahead of print.ABSTRACTOBJECTIVE: In our study, we aimed to investigate how whole blood viscosity (WBV) affects the development of contrast-induced nephropathy (CIN) in patients undergoing percutaneous coronary intervention (PCI).METHODS: In our study, 500 patients who applied to the cardiology clinic and underwent PCI for elective procedure, ST segment elevation myocardial infarction (STEMI), and non-STEMI were prospectively included. Before the procedure, we calculated WBV using the formula [(0.12×hematocrit) + (0.17×(total protein - 2.07)]...

This study is performed to investigate the relationship between elevated arterial lactate level and contrast-induced nephropathy (CIN).METHODS: Patients diagnosed with ST-segment elevated myocardial infarction (STEMI) were prospectively enrolled, with lactate measured within 0.5-1 hours before primary percutaneous coronary intervention (PCI). Patients with cardiopulmonary resuscitation, any forms of severe anaerobic condition, or end-stage renal disease undergoing dialysis were excluded. CIN was defined as an increase in serum creatinine ≥0.5 mg/dL or 25% within 72 hours after PCI. The Mehran Risk Score (MRS) is widely ...

We report the case of a 60-year-old man with vague gastrointestinal symptoms who waited more than 1 week to seek treatment for fear of COVID-19 infection. On presentation at another hospital, he was found to have had an anterior myocardial infarction, and he underwent percutaneous coronary intervention to stent an occluded proximal left anterior descending coronary artery. Subsequently, the patient experienced refractory cardiogenic shock and, during his transfer to our hospital, refractory ventricular tachycardia, which ultimately proved fatal.PMID:34652434 | DOI:10.14503/THIJ-20-7390

Korean J Intern Med. 2021 Oct 14. doi: 10.3904/kjim.2020.694. Online ahead of print.ABSTRACTBACKGROUND/AIMS: The clinical benefit of strict blood glucose-lowering therapy for patients with coronary artery disease (CAD) is still debated. We aimed to evaluate the long-term outcomes of patients with diabetes who underwent percutaneous coronary intervention (PCI), according to the mean hemoglobin A1c (HbA1c) level after PCI.METHODS: We evaluated 675 diabetes patients with CAD treated with PCI. We categorized the study population into three groups based on the mean observed HbA1c levels during the follow-up duration, as follows...
