Aims: Our study aimed to explore the temporal trajectory of eight circulating biomarkers, measured serially over 12 months, in a prospective observational cohort of patients with acute myocardial infarction (AMI) and to investigate the association between these biomarkers and left ventricular ejection fraction (LVEF) during follow-up assessments.

Methods And Results: We enrolled 155 patients admitted for a first AMI requiring percutaneous coronary intervention (PCI). Baseline characteristics, laboratory test results, and cardiac ultrasound examinations were collected at pre-PCI (H0), immediately post-PCI (H24), at discharge (D3), and at 6 months (M6) and 12 months (M12) post-PCI.

Background: The real incidence of atrial arrhythmia (AA) after patent foramen ovale (PFO) closure and whether this complication can be prevented remain unknown. We assessed whether flecainide is effective to prevent AA during the first 3 months after PFO closure, and whether 6 months of treatment with flecainide is more effective than 3 months to prevent AA after PFO closure.

Methods: AFLOAT (Assessment of Flecainide to Lower the Patent Foramen Ovale Closure Risk of Atrial Fibrillation or Tachycardia Trial) is a prospective, multicentre, randomized, open-label, superiority trial with a blind evaluation of all the end points (PROBE [Prospective Randomized Open, Blinded End Point] design).

Real-life data on the impact of sacubitril-valsartan and sodium-glucose cotransporter type 2 (SGLT-2) inhibitors on heart failure (HF) in France is lacking. Using French health insurance databases, we examined the ten-year evolution in HF medication use, focusing on SGLT-2 inhibitors and sacubitril/valsartan, and incidence of HF hospitalizations during the same period. We conducted a repeated cross-sectional study using medical-administrative data from French health insurance databases between 2014 and 2023.

Article Synopsis
  • * In a study involving 772 patients with cardiogenic shock, 21.3% had CKD, and these patients were generally older and had more health issues, which contributed to increased mortality.
  • * Renal replacement therapy (RRT) was associated with a higher risk of death regardless of CKD status, highlighting the need for collaborative care between cardiac and kidney specialists to better manage these patients.

Background: The discovery of novel biomarkers that improve current cardiovascular risk prediction models of acute coronary syndrome (ACS) is needed for the identification of very high-risk patients and therapeutic decision-making. Autophagy is a highly conserved catabolic mechanism for intracellular degradation of cellular components through lysosomes. The autophagy process helps maintain cardiac homeostasis and dysregulated autophagy has been described in cardiovascular conditions.
