Cardiometabolic heart failure with preserved ejection fraction (HFpEF) has emerged as a distinct and dominant endotype of HFpEF. Driven by prevalent comorbidities, its incidence and prevalence are projected to continue to rise amid the current global pandemic of obesity and metabolic disease. Recognizing the characteristic clinical and molecular features of cardiometabolic HFpEF is paramount for developing an efficacious therapeutic arsenal and improving clinical outcomes, challenges in which success to date has been modest. Studying relevant and clinically informative animal models of cardiometabolic HFpEF can afford valuable insights into the molecular underpinnings of this syndrome, allowing the possibility of novel advances with clinical relevance. Here, we outline the clinical and molecular features that define cardiometabolic HFpEF as a distinct endotype. We also discuss the bona fide animal models of cardiometabolic HFpEF currently available, as well as methods for developing new models.

Lipoprotein(a) (Lp[a]) is a genetic and often unmeasured contributor to atherosclerotic cardiovascular disease (ASCVD) risk. In this study, Lp(a) was estimated from exome data by quantifying Kringle IV subtype 2 repeats alongside a single-nucleotide variant–based genetic risk score. This method was applied to a diverse cohort (N = 76,147) from the Helix Research Network. The method better identified individuals with high Lp(a) levels, especially among individuals not genetically similar to Europeans. High genetic risk for high Lp(a) level was correlated with earlier and more frequent ASCVD diagnoses. Those with high genetic Lp(a) were more likely to have ASCVD without traditional risk factors present.

Proteomic profiling may provide insights into new biomarkers and pathways in coronary heart disease (CHD). We profiled ∼1,300 proteins in 1,967 Black individuals in the Jackson Heart Study and found Secreted and Transmembrane Protein 1 (SECTM1), a monocyte chemoattractant, to be our top novel finding associated with incident CHD. We validated our findings in the Cardiovascular Health Study. The top variant (rs116473040) associated with SECTM1 was associated with circulating monocyte percentage of white blood cells in a genomic database. In vivo studies demonstrated that recombinant SECTM1a increased the proportion of proatherogenic Ly6Chi monocytes, suggesting a pathway by which SECTM1 may contribute to CHD.

Although the prevalence of aortic regurgitation (AR), which causes eccentric remodeling and valvular heart disease (VHD), is increasing, suitable animal research models remain lacking. To address this issue, we established the first efficient, real-time visualized minimally invasive aortic regurgitation surgery mouse model by performing echocardiography-guided aortic valve tear using a modified insulin needle. The clinically relevant features of this AR model were verified by multimodal analysis, and feature genes closely associated with AR-induced VHD were obtained by time series analysis in conjunction with weighted gene co-expression network analysis. The results may provide comprehensive insights into the mechanistic study and potential therapeutic targets of AR-induced VHD.

Coronary artery bypass graft (CABG) uses the patient’s internal mammary artery and saphenous vein; however, unavailable or poor quality autologous vessels limit revascularization. This study addresses the critical need for alternative CABG conduits by evaluating a small diameter acellular tissue-engineered vessel ([sdATEV], 3.5 mm) in a primate model. Adult baboons (n = 5) underwent CABG to the right coronary artery (RCA) with an sdATEV. Patency, diameter, and cardiac function were longitudinally assessed by computed tomography angiography. All sdATEVs remained patent throughout the 6-month study. Computed tomography angiography demonstrated that the distal sdATEV diameter gradually remodeled to approximate the smaller baboon RCA. Histology and spatial transcriptomics revealed that sdATEVs recellularized with host endothelial and smooth muscle cells including a quiescent neomedia layer with gene expression patterns similar to the RCA, indicating that host cell ingrowth from the bypassed coronary artery regulates sdATEV diameter. These results suggest that the sdATEV is a durable alternative CABG conduit.

Cardiac fibrosis drives dysfunction in dilated cardiomyopathy (DCM); yet, effective therapies are limited. This study identifies FGFR1 as a critical target in cardiac fibrosis using transcriptomic and histological analyses of 58 human DCM biopsies. FGFR1 expression correlated with fibrosis severity, and inhibition by AZD4547 reduced fibrosis and improved cardiac function in organoid and murine models. These findings validate FGFR1 inhibition as a promising therapeutic strategy for mitigating fibrosis and improving outcomes in heart failure associated with DCM.
