RESUMO

BACKGROUND: Cardiogenic Shock (CS) complicating acute myocardial infarction (AMI) poses a significant mortality risk, suggesting the opportunity to implement effective mechanical circulatory support strategies. The comparative efficacy of Intra-Aortic Balloon Pump (IABP) and Impella in managing CS-AMI remains a subject of investigation. OBJECTIVE: This meta-analysis aims to evaluate the comparative effectiveness of Impella and IABP in managing CS-AMI, exploring mortality and adverse events. METHODS: A systematic search of major databases from inception to November 2023 identified eight studies, comprising 10,628 patients, comparing Impella and IABP in CS-AMI. Retrospective studies (preferably Propensity-matched) and Randomized Clinical Trials (RCTs) were included. RESULTS: Impella use exhibited significantly higher mortality (57% vs. 46%; OR: 1.44, 95% CI: 1.29-1.60; p < 0.001) and major bleeding (30% vs 15%; OR: 2.93, 95% CI: 1.67-5.13; p < 0.001). CONCLUSIONS: In unselected CS-AMI patients, Impella usage is associated with significantly higher mortality and major bleeding.

RESUMO

Ranolazine is an anti-anginal medication that has demonstrated antiarrhythmic properties by inhibiting both late sodium and potassium currents. Studies have shown promising results for ranolazine in treating both atrial fibrillation and ventricular arrhythmias, particularly when used in combination with other medications. This review explores ranolazine's mechanisms of action and its potential role in cardiac arrhythmias treatment in light of previous clinical studies.

RESUMO

Spontaneous coronary intramural hematoma (SCIH) is a rare but underdiagnosed condition, with dynamic evolution. We present a patient with acute chest pain and normal coronary angiogram undergoing work-up for myocardial infarction with nonobstructive coronary arteries. Cardiac magnetic resonance revealed an ischemic pattern, and subsequent angiography revealed coronary occlusion by SCIH. (Level of Difficulty: Intermediate.).

RESUMO

Heart failure (HF) is a complex, multifactorial, progressive clinical condition affecting 64.3 million people worldwide, with a strong impact in terms of morbidity, mortality and public health costs. In the last 50 years, along with a better understanding of HF physiopathology and in agreement with the four main models of HF, many therapeutic options have been developed. Recently, the European Society of Cardiology (ESC) HF guidelines enthusiastically introduced inhibitors of the sodium-glucose cotransporter (SGLT2i) as first line therapy for HF with reduced ejection fraction (HFrEF) in order to reduce hospitalizations and mortality. Despite drugs developed as hypoglycemic agents, data from the EMPA-REG OUTCOME trial encouraged the evaluation of the possible cardiovascular effects, showing SGLT2i beneficial effects on loading conditions, neurohormonal axes, heart cells' biochemistry and vascular stiffness, determining an improvement of each HF model. We want to give a boost to their use by increasing the knowledge of SGLT2-I and understanding the probable mechanisms of this new class of drugs, highlighting strengths and weaknesses, and providing a brief comment on major trials that made Gliflozins a cornerstone in HF therapy. Finally, aspects that may hinder SGLT2-i widespread utilization among different types of specialists, despite the guidelines' indications, will be discussed.
