[Myocardial infarction with elevation of the inferior and anterior ST segment: double artery is the culprit?].

Chest pain is one of the most frequent reasons for consultation in the emergency department. The most severe pathologies must be quickly ruled out within the diagnostic hypotheses: myocardial infarction (MI), aortic dissection, pulmonary thromboembolism, and pneumothorax. A frequent scenario is ST elevation MI due to a plaque accident.

[Endomyocardial biopsy in current practice: Technical Aspects, Indications and complications].

Endomyocardial biopsy (EMB) is an invasive procedure and a diagnostic tool used mainly on the follow-up of post-heart transplant rejection in the past years. Currently, it has an important role in the diagnosis of non-ischemic cardiomyopathies. EMB is frequently performed through a venous access to enter the right ventricle.

[True posterior infarction diagnosis. Report of three cases].

Acute Coronary Syndrome with ST segment elevation requires rapid reperfusion, which is why the timely identification of these conditions, based on the patient's symptoms and the correct interpretation of the EKG, is essential for therapeutic decisions. We report three patients with True Posterior Infarction and their difficult EKG diagnosis. The classic 12-lead EKG method is often not capable of supporting the diagnosis, so we recommend the use of posterior leads and mirror images observing inverted V1-V2-V3 leads on the classic EKG.

Consequences of COVID-19 pandemic on myocardial infarction reperfusion therapy and prognosis.

Unlabelled: Background The coronavirus disease (COVID-19) pandemic affected the prompt diagnosis and treatment of Acute myocardial infarction (AMI).

Aim: To characterize the clinical profile of patients with AMI during the COVID-19 pandemic, comparing them with a historical cohort.

Material And Methods: A case-control study of 96 patients with AMI transferred to a high-volume percutaneous coronary intervention (PCI) hospital between March and July 2020, and a historical cohort of 269 patients transferred during the same period in 2019.

[Myocardial infarction with non-obstructive coronary artery disease. Diagnostic value of intravascular imaging and cardiac resonance].

Background: Myocardial infarction with non-obstructive coronary artery disease (MINOCA) is common. Cardiac magnetic resonance (CMR) and intravascular imaging (IVI) may be useful for establishing its etiology.

Aim: To describe a population with MINOCA and its multi-image assessment using IVI or CMR.
