Cholesterol homeostasis is critically maintained through the interplay between intestinal cholesterol absorption and hepatic synthesis. A recent study identified a gut-derived hormone, Cholesin, which inhibits cholesterol synthesis in the liver, thereby reducing circulating cholesterol levels (ref: Hu doi.org/10.1016/j.cell.2024.02.024/). This discovery sheds light on previously unexplored mechanisms regulating cholesterol metabolism and suggests potential therapeutic targets for dyslipidemia. In a different context, the presence of microplastics and nanoplastics (MNPs) in atheromas has been linked to increased cardiovascular risk. A study found that patients with MNPs in their carotid artery plaques had a significantly higher risk of experiencing myocardial infarction, stroke, or death compared to those without MNPs, with a hazard ratio of 4.53 (ref: Marfella doi.org/10.1056/NEJMoa2309822/). Furthermore, fixed-dose combination (FDC) therapy has emerged as a promising strategy for preventing atherosclerotic cardiovascular disease (ASCVD). A systematic review of randomized trials indicated that FDC therapy, which includes both blood pressure-lowering and lipid-lowering agents, effectively targets multiple risk factors for ASCVD (ref: Agarwal doi.org/10.1038/s41591-024-02896-w/). Lastly, the impact of statin therapy on new-onset diabetes was evaluated through a meta-analysis of individual participant data, revealing that statins may increase diabetes risk, although the timing and magnitude of this effect require further investigation (ref: doi.org/10.1016/S2213-8587(24)00040-8/).

The role of inflammation in atherosclerosis has garnered significant attention, particularly regarding the cellular composition of atherosclerotic plaques.

Heart failure remains a critical area of research, particularly regarding treatment strategies that enhance patient outcomes. The DAPA-HF trial evaluated the impact of dapagliflozin on days of full health lost, integrating recurrent hospitalizations and overall well-being into its analysis. This trial demonstrated that dapagliflozin significantly improves outcomes in patients with heart failure and reduced ejection fraction (ref: Kondo doi.org/10.1016/j.jacc.2024.03.385/). Additionally, the implementation of uniform cardiac troponin thresholds for ruling out myocardial infarction was found to be safe and effective across genders, identifying a higher proportion of low-risk female patients compared to males (ref: Li doi.org/10.1016/j.jacc.2024.03.365/). The efficacy of sacubitril/valsartan in patients hospitalized for decompensated heart failure was also assessed, revealing its potential benefits across the ejection fraction spectrum (ref: Morrow doi.org/10.1016/j.jacc.2024.01.027/). These findings collectively emphasize the importance of tailored treatment strategies in managing heart failure and improving patient quality of life.

Hypertension continues to be a leading risk factor for cardiovascular disease, with recent studies highlighting the genetic underpinnings of blood pressure traits. A genome-wide association study identified 1,346 loci associated with blood pressure, including 412 that were female-specific, suggesting significant sex differences in genetic susceptibility to hypertension (ref: Yang doi.org/10.1038/s41591-024-02858-2/). Furthermore, a cross-sectional analysis of self-reported hypertension prevalence in the U.S. revealed that approximately half of adults are affected, with notable disparities based on race and socioeconomic status (ref: Sekkarie doi.org/10.15585/mmwr.mm7309a1/). The STEP trial examined the incidence of cardiac conduction system diseases in hypertensive patients, finding no significant difference in new-onset cases between intensive and standard blood pressure control groups (ref: Zhao doi.org/10.1038/s43587-024-00591-6/). These studies underscore the multifaceted nature of hypertension and the need for targeted interventions to manage this pervasive condition.

The interplay between genetic and environmental factors in cardiovascular disease is increasingly recognized, with recent research shedding light on various mechanisms. A study on the glycine transporter 1 (GlyT1) elucidated its role in neurotransmission and potential implications for drug design, which could extend to cardiovascular health (ref: Wei doi.org/10.1016/j.cell.2024.02.026/). Additionally, the ENCODE Consortium's multicenter analysis of noncoding CRISPRi screens has advanced our understanding of gene regulatory landscapes, providing insights into the genetic factors influencing cardiovascular disease (ref: Yao doi.org/10.1038/s41592-024-02216-7/). The resilience of hematopoietic responses to physiological demands was also explored, highlighting the bone marrow's adaptability in producing blood cells under stress (ref: Wu doi.org/10.1038/s41586-024-07186-6/). Collectively, these findings emphasize the complexity of cardiovascular disease etiology, integrating genetic predispositions with environmental influences.
