Rationale and design of a randomized clinical trial evaluating the efficacy of mechanical neuroprotection in reducing the risk of silent brain infarcts associated with percutaneous left atrial appendage closure: study protocol for a LAAC-SBI trial.

Background: Left atrial appendage closure (LAAC) procedures prevent cardioembolic stroke in patients with atrial fibrillation who have contraindications to oral anticoagulant medications. However, these procedures carry certain risks of peri-procedural complications. One such complication is silent brain infarcts (SBI), which can lead to cognitive impairment and mood disturbances.

The prognostic impact of therapeutic hypothermia after a sudden cardiac arrest in the course of myocardial infarction.

Background: Mild therapeutic hypothermia (MTH) is one of the treatment methods recommended in post-sudden cardiac arrest (SCA) patients who remain unconscious after cardiopulmonary resuscitation. The present study aimed at assessing the prognostic impact of intravascular MTH on invasively treated patients with an acute myocardial infarction complicated by SCA.

Methods: The presented data were collected via a single-center retrospective analysis of the hospitalization and follow-up of 54 patients with post-myocardial infarction complicated by SCA.

Therapeutic hypothermia and postreperfusion myocardial injury in myocardial infarction.

Myocardial infarction is one of the main causes of death worldwide. Since the introduction of primary percutaneous coronary intervention (PPCI), the rate of patients who die of a myocardial infarction or suffer from numerous complications afterwards has significantly decreased. During PPCI, the patient sustains postreperfusion myocardial injury, which entails an extension of the myocardial infarct size related to ischemia.
