Is the D-Dimer Useful in High-Probabilty Pulmonary Embolism?

Bottom Line Up Top: A negative D-Dimer likely excludes significant pulmonary embolism (PE) in all patients but the low chance of getting a negative result makes a D-Dimer first approach of low clinical utility in the high pre-test probability ...

Balancing Innovation and Reality: Evaluating AI’s Role in STEMI Diagnosis

Background: ST-segment elevation myocardial infarction (STEMI) is a critical condition requiring rapid diagnosis and intervention. While ECGs play a central role in detecting STEMI, misinterpretations often occur, leading to unnecessary catheterization or missed diagnoses. With advancements in artificial intelligence (AI), ...

D-Dimer in High-Risk PE: A Gamble Worth Taking?

\Background: The current standard care for evaluating pulmonary embolism (PE) advises against D-dimer testing in patients with a high clinical probability. European and American guidelines emphasize a sequential diagnostic approach based on pretest probability assessment using either a formal clinical ...

The PROTECTION Trial – A Randomized Trial of Intravenous Amino Acids for Kidney Protection

Background Information: Acute kidney injury (AKI) is one of the most frequent complications of cardiac surgery and the cause is complex. Renal hypoperfusion from decreased glomerular filtration rate after cardiopulmonary bypass is a major contributor.1 This in combination with exogenous ...
