We investigated the effects of aficamten on cardiac muscle structure, biochemical activity, and contractile function. Aficamten does not structurally sequester myosin heads along the thick filament. It inhibits ATPase activity by decreasing myosin ATPase cycling kinetics, with the emergence of a super slow biochemical nucleotide turnover. This results in decreased force and calcium sensitivity without altering cross-bridge cycling. Our myofibril mechanical assay showed inhibition of force with accelerated relaxation. In engineered heart tissues, while mavacamten and aficamten inhibit cardiac twitch forces, mavacamten reduces the activation kinetics while both accelerate relaxation.

Myocardial recovery after left ventricular assist device (LVAD) support is a critical phenomenon that allows advanced heart failure patients to retain their native heart. We quantified targeted sphingolipids in serum and cardiac tissue of patients who exhibited recovery post-LVAD. Our analysis revealed sustained elevated circulating ceramides levels in nonresponders post-LVAD, whereas responders showed reduced sphingosine-1-phosphate (S1P) levels. In contrast, cardiac tissue from nonresponders displayed increased S1P levels. We suggest that diminished ceramide and S1P may contribute to an increased likelihood of recovery after LVAD support. Collectively, our findings implicate the sphingolipid metabolic pathway as a potential therapeutic target to promote myocardial recovery after mechanical support.

Previous studies have shown that Nox4 activates eIF2α/ATF4 signaling during the integrated stress response (ISR) and protects heart injury. However, their roles in calcific aortic valve disease (CAVD) remain unclear. Here, we show that both ATF4 and Nox4 are up-regulated in porcine aortic valve interstitial cells (AVIC) and in human aortic valves with CAVD. Nox4 knockdown promotes while Nox4 overexpression suppresses CAVD by modulating ISR. Importantly, ISR activators Guanabenz and Sephin1 effectively attenuate AVIC osteoblastic-like differentiation and mitigate CAVD in rabbits and mice, respectively. These findings highlight that pharmacological enhancement of the ISR is a promising therapeutic strategy for CAVD.

Vascular calcification arises from the osteogenic transdifferentiation of vascular smooth muscle cells (VSMCs) and is a hallmark of many cardiovascular pathologies. This study identifies Tet2, a DNA demethylase, as a critical epigenetic regulator that prevents this phenotypic switch. VSMC-specific loss of Tet2 promotes osteogenic differentiation, apoptosis, increased infiltration of Trem2hi macrophages and medial aortic calcification. High-dose ascorbate used to enhance Tet2 activity significantly reduced calcification and preserved aortic structure in mice. These findings support Tet2 reactivation as a potential therapeutic strategy to prevent or reverse vascular calcification in cardiovascular disease.

Safe and efficient in vivo delivery of advanced therapies (ATs) remains a major challenge hindering their path to clinical adoption. We present a novel, fully percutaneous, catheter-based locoregional perfusion (LRP) system for targeted delivery of ATs, minimizing systemic exposure. Using principles from extracorporeal membrane oxygenation and cardiovascular perfusion, we developed and validated the LRP concept in porcine models, focusing on the kidney as a clinically relevant target. Custom catheter prototypes enabled safe, isolated perfusion of the kidney. Using adeno-associated viruses (AAVs) as model cargos, LRP achieved up to 69,000-fold higher vector retention within the LRP circulation than systemic circulation, and significantly reduced delivery to off-target organs such as the liver and spleen. AAV5 showed the highest transduction efficiency, with up to 75-fold greater gene expression. These findings demonstrate the feasibility, safety, and precision of LRP for organ-specific AT delivery while preventing plausible off-target toxicity. It may therefore represent a unique platform for next-generation delivery of AT and potentially beyond, including other therapeutic agents such as pharmaco- or chemotherapy to the target-organ.

Systemic lupus erythematosus (SLE) is a complex autoimmune disease with an increased risk of vascular dysfunction and cardiovascular disease. We validate our previously developed Systemic Lupus Erythematosus Activity Platelet-Gene Expression Signature (SLAP-GES) score and investigate its relationship with platelet activity and vascular health. SLAP-GES was associated with the SLE Disease Activity Index (Padj < 0.001) and consistent over time (r = 0.76; P = 9 × 10−5). Moreover, SLAP-GES was associated increased platelet aggregation in response to submaximal epinephrine (P = 0.084), leukocyte platelet aggregates (P = 0.014), and neutrophil platelet aggregates (P = 0.043). SLAP-GES was also associated with impaired glycocalyx (P = 0.011) and brachial artery flow-mediated dilation (P = 0.045). Altogether, SLAP-GES is associated with SLE disease activity, platelet activity, and impaired vascular health.

There are currently no reliable serum biomarkers to aid in the diagnosis of peripheral artery disease (PAD). We hypothesized that circulating fatty acid synthase (cFAS) can be an independent diagnostic biomarker for PAD. Serum cFAS and demographics were compared for patients with and without PAD or chronic limb threatening ischemia (CLTI). Patients with PAD or CLTI had significantly higher serum cFAS content. We observed optimal cutoffs for cFAS in distinguishing between individuals with and without PAD or CLTI. Our study demonstrates that cFAS is an independent serum-based diagnostic biomarker for PAD, can distinguish between patients with PAD vs CLTI, and may predict disease severity.
