Pretreatment With Unfractionated Heparin in ST-Elevation Myocardial Infarction—a Propensity Score Matching Analysis.

Background: Patients with ST-segment elevation myocardial infarction (STEMI) are often pretreated with unfractionated heparin (UFH) before a primary percutaneous coronary intervention (PPCI). UFH pretreatment is intended to lessen the thrombotic burden, but there have been conflicting study findings on its safety and efficacy. We assessed the risks and benefits of UFH pretreatment with a retrospective analysis of registry data from the STEMI network of a German metropolitan region.

New categorization of chest pain: noncardiac is in, atypical is out!

Chest pain poses a diagnostic challenge in the emergency department and requires a thorough clinical assessment. The traditional distinction between "atypical" and "typical" chest pain carries the risk of not addressing nonischemic clinical pictures. The newly conceived subdivision into cardiac, possibly cardiac, and (probably) noncardiac causes of the presenting symptom complex addresses a much more interdisciplinary approach to a symptom-oriented diagnostic algorithm.

A nationwide analysis of reperfusion therapies for pulmonary embolism in older patients with frailty.

Background: Reperfusion therapy is challenging in the elderly. Catheter-directed therapies are an alternative for higher-risk pulmonary embolism (PE) patients if systemic thrombolysis (ST) is contraindicated or has failed. Their safety has not been evaluated in specific vulnerable populations.
