Study Design and Rationale of a Randomized Trial Comparing Aspirin-Sarpogrelate Combination Therapy with Aspirin Monotherapy: Effects on Blood Viscosity and Microcirculation in Cardiovascular Patients.

Coronary artery disease (CAD) and peripheral artery disease (PAD) are associated with increased blood viscosity, which contributes to vascular inflammation and impaired microcirculation. Blood viscosity plays a crucial role in disease progression, influencing endothelial function and tissue perfusion. Sarpogrelate hydrochloride, a serotonin receptor antagonist, has antiplatelet and vasodilatory properties that may improve microvascular function and blood rheology.

BMI and Deescalation From Ticagrelor to Clopidogrel in Patients With Acute Myocardial Infarction: A Post Hoc Analysis of the TALOS-AMI Trial.

Importance: The potential benefits of P2Y12 inhibitor deescalation for acute myocardial infarction after percutaneous coronary intervention may be influenced by body mass index (BMI).

Objectives: To investigate the association of BMI on deescalation outcomes after 12 months in patients with acute myocardial infarction after percutaneous coronary intervention who were initially treated with aspirin plus ticagrelor for 1 month, and to assess whether BMI-based switching from aspirin plus ticagrelor (active control strategy) to aspirin plus clopidogrel (deescalation strategy) is associated with individualized benefits.

Design, Setting, And Participants: This study is a post hoc analysis, based on BMI, of data from the TALOS-AMI (Ticagrelor vs Clopidogrel in Stabilized Patients with Acute Myocardial Infarction) randomized clinical trial.

Epigenomic landscape exhibits interferon signaling suppression in the patient of myocarditis after BNT162b2 vaccination.

After the outbreak of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, a novel mRNA vaccine (BNT162b2) was developed at an unprecedented speed. Although most countries have achieved widespread immunity from vaccines and infections, yet people, even who have recovered from SARS-CoV-2 infection, are recommended to receive vaccination due to their effectiveness in lowering the risk of recurrent infection. However, the BNT162b2 vaccine has been reported to increase the risk of myocarditis.

Single-cell sequencing of PBMC characterizes the altered transcriptomic landscape of classical monocytes in BNT162b2-induced myocarditis.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been the most dangerous threat to public health worldwide for the last few years, which led to the development of the novel mRNA vaccine (BNT162b2). However, BNT162b2 vaccination is known to be associated with myocarditis. Here, as an attempt to determine the pathogenesis of the disease and to develop biomarkers to determine whether subjects likely proceed to myocarditis after vaccination, we conducted a time series analysis of peripheral blood mononuclear cells of a patient with BNT162b2-induced myocarditis.

The Peripheral Immune Landscape in a Patient with Myocarditis after the Administration of BNT162b2 mRNA Vaccine.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has posed a serious threat to global public health. A novel vaccine made from messenger RNA (mRNA) has been developed and approved for use at an unprecedented pace. However, an increased risk of myocarditis has been reported after BNT162b2 mRNA vaccination due to unknown causes.
