A case of a 72-year-old female who was admitted for elective dual-chamber pacemaker implantation, is presented. A few hours after the procedure the patient developed chest pain with ST-segment elevation in ECG and a significant increase in the troponin I level. An acute myocardial infarction was diagnosed. Urgent coronary angiography revealed normal coronary arteries without spasm. Possible causes of acute myocardial infarction following pacemaker implantation are discussed.

Introduction: New Onset Atrial Fibrillation (NOAF) is the most common arrhythmia in intensive care. Complications of NOAF include thromboembolic events such as myocardial infarction and stroke, which contribute to a greater risk of mortality. Inflammatory and coagulation biomarkers in sepsis are thought to be associated with NOAF development.

Background: Impaired renal function can increase cardiac troponin levels due to reduced elimination, potentially affecting its diagnostic utility. Limited data exist on high-sensitivity cardiac troponin I (hs-cTnI) kinetics after cardiac surgery relative to renal function. This study evaluates how impaired renal function influences hs-cTnI kinetics following cardiac surgery, distinguishing between patients with and without postoperative myocardial infarction (PMI).

The Swedish quality register AmbuReg collects all the country's ambulance missions. There is an increasing demand on the Emergency Medical Services (EMS) due to decreasing hospital resources and referral to self-care, primary care and mobile teams. This, in combination with fast tracks for patients with myocardial infarction, stroke, hip fracture or sepsis, increases the requirement for optimal triage at the scene.

Background: Previous studies suggest similar cardiovascular (CV) benefits for either percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) in patients with left main coronary artery disease (LMCAD). However, limited data exist on the influence of prior cerebrovascular disease (CEVD). Thus, we aim to compare the CV outcomes in patients with LMCAD and prior CEVD, undergoing either PCI or CABG.
