Article Synopsis
  • Intensive cardiac care units (ICCU) in France have diversified from monitoring arrhythmias post-heart attack to treating various cardiac conditions, with acute coronary syndromes (ACS) being the most common cause for admission.
  • A study of 1499 patients revealed that many have additional health concerns, with a significant portion requiring advanced therapies but a majority not needing invasive procedures.
  • Overall, patients tend to have brief hospital stays with a low rate of major adverse events, although acute heart failure (AHF) patients face higher risks and resource use.

Article Synopsis
  • The study investigated the prevalence of recreational drug use among patients admitted to intensive cardiac care units (ICCU) and its effect on major adverse events (MAEs) during hospitalization.
  • Out of 1499 patients tested, 11% were positive for recreational drugs, with cannabis being the most common, yet only 57% self-reported their use.
  • Patients using recreational drugs experienced significantly higher rates of in-hospital MAEs compared to non-users, with drugs like cannabis, cocaine, and MDMA showing independent associations with worse outcomes.

Transthyretin cardiac amyloidosis (ATTR-CA) is an increasingly recognized disease that often results in heart failure and death. Traditionally, biological staging systems are used to stratify disease severity. Reduced aerobic capacity has recently been described as useful in identifying higher risk of cardiovascular events and death.

The rod-shaped adult cardiomyocyte (CM) harbors a unique architecture of its lateral surface with periodic crests, relying on the presence of subsarcolemmal mitochondria (SSM) with unknown role. Here, we investigated the development and functional role of CM crests during the postnatal period. We found in rodents that CM crest maturation occurs late between postnatal day 20 (P20) and P60 through both SSM biogenesis, swelling and crest-crest lateral interactions between adjacent CM, promoting tissue compaction.

BACKGROUND Heart failure (HF) most commonly occurs due to ischemic heart disease from stenotic coronary artery disease (CAD). HF is classified into 3 groups based on the percentage of the ejection fraction (EF): reduced (HFrEF), mid-range (HFmrEF), and preserved (HFpEF). This retrospective study included 573 patients who presented with HF based on the evaluation of EF and were evaluated for CAD by coronary angiography before undergoing coronary angioplasty at a single center in Toulouse, France.

Article Synopsis
  • The Critical COVID France (CCF) study examined the effects of COVID-19 on 2868 hospitalized patients, focusing on those aged 18-45, who made up 11.2% of the sample.
  • Young patients (18-45 years old) had lower rates of severe outcomes like ICU transfers and in-hospital deaths compared to older patients, but they experienced higher rates of certain cardiovascular issues like pericarditis and myocarditis.
  • Despite lower overall severity, COVID-19 still posed significant cardiovascular risks for young patients, highlighting the importance of understanding its impacts on this age group.

Higher rates of severe COVID-19 have been reported in kidney transplant recipients (KTRs) compared to nontransplant patients. We aimed to determine if poorer outcomes were specifically related to chronic immunosuppression or underlying comorbidities. We used a 1:1 propensity score-matching method to compare survival and severe disease-free survival (defined as death and/or need for intensive care unit [ICU]) incidence in hospitalized KTRs and nontransplant control patients between February 26 and May 22, 2020.
