Background: Chronic kidney disease (CKD) is associated with higher risk of myocardial infarction and anemia. Among patients with anemia and CKD who experience myocardial infarction, it remains uncertain if a liberal red blood cell transfusion threshold strategy (hemoglobin cutoff [Hgb] < 10 g/dL) is superior to a restrictive transfusion threshold (Hgb 7-8 g/dL) strategy.

Methods: Among the 3,504 patients enrolled in the Myocardial Ischemia and Transfusion (MINT) trial with non-missing creatinine, we compared baseline characteristics and 30-day and 6-month outcomes of patients without CKD (N = 1279), CKD with eGFR 30-60 mL/min/1.

Article Synopsis
  • - Atrial fibrillation (AF) is more common in patients with type 2 diabetes and is linked to worse health outcomes; a trial called Harmony Outcomes was conducted to study the effects of albiglutide, a GLP-1 receptor agonist, on cardiovascular events in these patients.
  • - The trial included nearly 9,500 participants over 1.6 years and found that those with a history of AF had a higher rate of major adverse cardiac events, but albiglutide treatment reduced these events regardless of AF history.
  • - Although both groups on albiglutide experienced fewer AF events than those receiving a placebo, the reduction wasn't statistically significant, indicating that albiglutide can lower cardiovascular risks without

Article Synopsis
  • Traditional analyses in clinical trials for antithrombotic agents evaluate bleeding and ischemic events separately, which have limitations; this study proposes using days alive and out of hospital (DAOH) as an alternative endpoint.
  • The AUGUSTUS trial involving 4614 patients compared two treatments (apixaban vs. warfarin and aspirin vs. placebo) and measured DAOH, finding no significant differences between treatment groups.
  • Despite apixaban showing lower rates of major bleeding and hospitalization, the study concludes that DAOH may not effectively capture the impact of antithrombotic therapies for patients with atrial fibrillation and acute coronary syndrome.

Background: In the AUGUSTUS trial (An Open-Label, 2 x 2 Factorial, Randomized Controlled, Clinical Trial to Evaluate the Safety of Apixaban vs Vitamin K Antagonist and Aspirin vs Aspirin Placebo in Patients With Atrial Fibrillation and Acute Coronary Syndrome or Percutaneous Coronary Intervention), the combination of dual antiplatelet therapy plus oral anticoagulation increased the risk of bleeding without reducing ischemic events compared with a P2Y12 inhibitor plus oral anticoagulation among patients with atrial fibrillation and acute coronary syndrome or elective percutaneous coronary intervention. However, AUGUSTUS enrolled patients up to 14 days after acute coronary syndrome or percutaneous coronary intervention, and there may be a benefit to dual antiplatelet therapy plus oral anticoagulation early after an ischemic event.

Methods: In this secondary analysis of AUGUSTUS, we divided patients into groups based on whether they were enrolled <6 days (early) or ≥6 days (later) after their index acute coronary syndrome or percutaneous coronary intervention, and tested the interaction between time from the index event to enrollment and randomized treatment (apixaban versus vitamin K antagonist and aspirin versus placebo) on 30-day and 6-month clinical outcomes using Cox proportional hazards models.

Article Synopsis
  • The study investigates whether living in rural areas affects mortality rates in patients with acute myocardial infarction (AMI) and heart failure (HF), which may impact healthcare access and outcomes.
  • A meta-analysis of 37 studies was conducted, encompassing over 21 million AMI patients and nearly 18 million HF patients, to compare rural versus urban patient mortality, focusing on all-cause mortality.
  • Results indicate that although rural AMI patients are slightly older and have a higher proportion of females, the analysis aims to provide insights into mortality differences and the factors that may contribute to any observed disparities between rural and urban populations.

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 study was conducted on individuals aged 70 and older to assess the frequency and burden of atrial fibrillation (AF) using a 14-day electrocardiograph monitor.
  • Out of 5,684 participants, 4.4% were found to have AF, with the majority having paroxysmal AF of low burden; the median time spent in AF was only about 75 minutes.
  • The research highlighted that while most AF cases had low burden, a significant portion had extended episodes, raising potential concerns for increased stroke risk and suggesting the need for targeted AF screening approaches.

Background: The ISCHEMIA trial (International Study of Comparative Health Effectiveness with Medical and Invasive Approaches) demonstrated greater health status benefits with an initial invasive strategy, as compared with a conservative one, for patients with chronic coronary disease and moderate or severe ischemia. Whether these benefits vary globally is important to understand to support global adoption of the results.

Methods: We analyzed participants' disease-specific health status using the validated 7-item Seattle Angina Questionnaire (SAQ: >5-point differences are clinically important) at baseline and over 1-year follow-up across 37 countries in 6 international regions.

Background: Patients hospitalised for COVID-19 are at risk for multiorgan failure and death. Sodium-glucose co-transporter-2 (SGLT2) inhibitors provide cardiovascular and kidney protection in patients with cardiometabolic conditions and could provide organ protection during COVID-19. We aimed to investigate whether SGLT2 inhibitors can reduce the need for organ support in patients hospitalised for COVID-19.

Background: Following an acute myocardial infarction (AMI), patients remain at risk for subsequent cardiovascular (CV) events. In the AEGIS-II trial, CSL112, a human apolipoprotein A-I derived from plasma that enhances cholesterol efflux, did not significantly reduce the first occurrence of CV death, myocardial infarction (MI), or stroke through 90 days compared with placebo. However, an analysis involving only the first event may not capture the totality of the clinical impact of an intervention because patients may experience multiple events.

Background: Atrial fibrillation (AF) often remains undiagnosed, and it independently raises the risk of ischemic stroke, which is largely reversible by oral anticoagulation. Although randomized trials using longer term screening approaches increase identification of AF, no studies have established that AF screening lowers stroke rates.

Objectives: To address this knowledge gap, the GUARD-AF (Reducing Stroke by Screening for Undiagnosed Atrial Fibrillation in Elderly Individuals) trial screened participants in primary care practices using a 14-day continuous electrocardiographic monitor to determine whether screening for AF coupled with physician/patient decision-making to use oral anticoagulation reduces stroke and provides a net clinical benefit compared with usual care.
