Background: Patients with a history of coronary revascularization are at a higher risk for subsequent cardiovascular events and all-cause mortality. Lowering LDL-cholesterol (LDL-C) levels post-revascularization significantly reduces these risks.

Methods: This analysis compared LDL-C-lowering therapies at baseline and over time among patients with and without prior coronary revascularization in the GOULD registry (a prospective multicenter cohort study).

Aims: The extent of irreversible cardiomyocyte necrosis after acute myocardial infarction (AMI) is a major determinant of residual left ventricular (LV) function and clinical outcome. Cell therapy based on CD34+ cells has emerged as an option to help repair the myocardium and to improve outcomes. The dose of CD34+ cells and the route of administration are two important factors that will determine the clinical effectiveness of the approach, provided it is robust and feasible.

Current evidence indicates that dual antiplatelet therapy with aspirin plus a P2Y inhibitor is essential for the prevention of thrombotic events after percutaneous coronary interventions. However, dual antiplatelet therapy is associated with increased bleeding which may outweigh the benefits. This has set the foundations for customizing antiplatelet treatments to the individual patient.

The prevalence of obstructive sleep apnea (OSA) is on the rise, driven by various factors including more sensitive diagnostic criteria, increased awareness, enhanced technology through at-home testing enabling easy and cost-effective diagnosis, and a growing incidence of comorbid conditions such as obesity. Treating symptomatic patients with OSA syndrome to enhance quality of life remains a cornerstone approach. However, there is a lack of consensus regarding treatment to improve cardiovascular disease (CVD) outcomes, particularly in light of overall negative results from several randomized controlled trials (RCT) indicating no benefit of positive airway pressure (PAP) therapy on primary and secondary CVD events.

Article Synopsis
  • Clinical trials indicate that using a mobile stroke unit (MSU) for prehospital management can lead to better outcomes for acute ischemic stroke patients who may need thrombolysis, but real-world data is limited.
  • This study aimed to compare the effects of prehospital MSU management versus standard emergency services (EMS) on patient disability levels at the time of hospital discharge.
  • The analysis included over 19,000 patients treated across multiple hospitals, revealing that those managed in an MSU had improved functional outcomes compared to those receiving standard EMS care.*

Background: Accurate bleeding risk stratification after percutaneous coronary intervention (PCI) is important for treatment individualization. However, there is still an unmet need for a more precise and standardized identification of high bleeding risk patients. We derived and validated a novel bleeding risk score by augmenting the PRECISE-DAPT score with the Academic Research Consortium for High Bleeding Risk (ARC-HBR) criteria.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is linked to high mortality, primarily through an intense inflammatory response. Diacerein has emerged as a potential therapy for COVID-19 due to its potential impact in decreasing the inflammasome activation and coronavirus replication. This study aims to explore diacerein's influence in inhibiting both viral replication and the inflammatory response after SARS-CoV-2 infection.

Article Synopsis
  • The study investigates the use of cangrelor in patients with myocardial infarction (MI) who also have cardiogenic shock (CS), focusing on the infusion duration and transition to oral medications.
  • A total of 249 patients with CS were analyzed, with significant observations on demographics, infusion times, and the occurrence of major adverse cardiovascular events (MACEs) and bleeding risks.
  • The findings showed that patients with CS had longer cangrelor infusions compared to others, and that the use of mechanical circulatory support (MCS) was linked to longer infusion times and an increased risk of bleeding.

Article Synopsis
  • There’s a debate about how long patients with heart problems should take two types of medicine together, called dual antiplatelet therapy (DAPT).
  • Researchers wanted to see how effective and safe different lengths of DAPT are for patients who have serious heart issues and receive a special procedure to help their hearts.
  • They found that taking DAPT for just 1 month followed by another medicine might reduce serious bleeding, but didn't change the number of heart problems compared to taking DAPT for 12 months.

Article Synopsis
  • A meta-analysis of randomized, sham-controlled trials was conducted to evaluate the effectiveness and safety of catheter-based renal denervation (RDN) in treating hypertension, involving 10 trials with a total of 2,478 patients.
  • The study found that RDN significantly lowered both 24-hour and office systolic and diastolic blood pressure compared to sham procedures, without a notable difference in complications or changes in renal function.
  • Overall, RDN appears to be a safe and effective method for reducing blood pressure in patients with hypertension, although significant variability was noted among the studies analyzed.

Article Synopsis
  • The study evaluated the PACAS risk model's ability to identify patients at high risk for severe asymptomatic carotid artery stenosis (ACAS) and predict future strokes and cardiovascular disease (CVD) risk.
  • It involved 26,384 patients aged 45-80, finding that 6.3% had severe ACAS at baseline and that higher PACAS scores correlated with increased incidences of stroke and CVD over roughly 70,000 patient-years of follow-up.
  • The PACAS model was confirmed to effectively discriminate and calibrate risk levels, indicating that patients with higher scores had a significantly higher prevalence of severe ACAS and related events during the follow-up period.

  • SGLT2 inhibitors like sotagliflozin show promise in improving health status for heart failure patients, but effects of SGLT1/SGLT2 inhibition remain unclear.* -
  • In the SOLOIST-WHF trial, patients taking sotagliflozin after a heart failure episode experienced a significant improvement in their Kansas City Cardiomyopathy Questionnaire-12 (KCCQ-12) scores compared to those on placebo.* -
  • Overall, sotagliflozin not only reduced hospitalizations and cardiovascular deaths but also led to improved symptoms and quality of life within four months, benefiting patients regardless of their left ventricular ejection fraction.*

Article Synopsis
  • The study investigates the relationship between triglyceride levels and the cardiovascular benefits of alirocumab compared to placebo in patients with recent acute coronary syndrome (ACS) who are on statin therapy.
  • Results showed that higher baseline triglyceride levels were linked to an increased risk of major adverse cardiovascular events (MACE), whereas alirocumab significantly lowered LDL cholesterol and reduced MACE risk.
  • While alirocumab led to a notable decrease in triglycerides, the reduction did not correlate with a lower risk of MACE, suggesting baseline triglyceride levels are more important for cardiovascular risk than reductions achieved through treatment.

Article Synopsis
  • In randomized trials, deaths that are unrelated to the primary outcome being studied are classified as competing risks, and traditional analysis methods may inaccurately treat these deaths like censored data.
  • The Fine and Gray model, often used for analyzing competing risks, can be misapplied and potentially deliver misleading results.
  • The authors suggest a new multiple imputation approach that better accounts for the risk factors associated with both death and the outcomes of interest, and they provide recommendations for future trials based on their findings from three cardiovascular studies.

Since the 1960s, cardiologists have adopted several binary classification systems for acute myocardial infarction (MI) that facilitated improved patient management. Conversely, for chronic stable manifestations of myocardial ischemia, various classifications have emerged over time, often with conflicting terminology-eg, "stable coronary artery disease" (CAD), "stable ischemic heart disease," and "chronic coronary syndromes" (CCS). While the 2019 European guidelines introduced CCS to impart symmetry with "acute coronary syndromes" (ACS), the 2023 American guidelines endorsed the alternative term "chronic coronary disease.
