However, even after achieving low levels, some patients continued to have cardiovascular events, a phenomenon known as residual cardiovascular risk. This phenomenon indicates the complexity of atherosclerosis, not limited to a simple LDL-driven process. Vascular inflammation persists even in the presence of well-controlled lipids and is largely mediated by the NLRP3-interleukin-1β-interleukin-6 signaling pathway, which has been shown to be a viable therapeutic target in the CANTOS, COLCOT, and LoDoCo2 trials. Triglyceride-rich lipoproteins and remnant cholesterol accumulate in the arterial intima and drive atherogenesis independent of LDL-C, with icosapent ethyl showing meaningful cardiovascular benefit in the REDUCE-IT trial. Apolipoprotein B reflects the true number of circulating atherogenic particles that LDL-C alone fails to identify, especially in patients with metabolic disease. Lipoprotein(a) is an inherited risk factor that statins barely affect, and it carries a well-established association with myocardial infarction, stroke, and aortic stenosis; RNA-based therapies targeting it are now in late-stage trials. The 2026 ACC/AHA Dyslipidemia Guideline now carries a Class I recommendation for universal Lp(a) measurement at least once in all adults. Impaired HDL function, insulin resistance, and a prothrombotic environment provide further risk. GLP-1 receptor agonists and SGLT2 inhibitors have emerged as important contributors to residual cardiovascular risk reduction in patients with metabolic dysfunction, showing consistent cardiovascular benefit on top of their background of statin therapy, with mechanisms that extend far beyond glycemic control. Coronary imaging, such as coronary calcium scoring and coronary CT angiography, can identify high-risk plaque features that persist despite aggressive lipid-lowering. Taken together, these findings make the case that LDL-C treatment is important but incomplete. A more comprehensive approach is required to meaningfully reduce the residual risk, one that considers apoB, remnant cholesterol, inflammation, lipoprotein(a), and metabolic risk.</p>","PeriodicalId":7427,"journal":{"name":"American journal of cardiovascular disease","volume":"16 4","pages":"234-246"},"PeriodicalIF":1.4,"publicationDate":"2026-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13601777/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149035946","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Originally marketed as less harmful than burning cigarettes, e-cigarettes have gained enormous popularity, especially among young adults, thus leading to nicotine addiction and new trends of cardiovascular damage. Even though e-cigarettes limit exposure to products of combustion, they supply similar doses of nicotine and other elements such as aldehydes, metals, and flavoring by-products, whose cardiovascular effects are incompletely characterized. This narrative review addresses a comprehensive analysis of the cardiovascular effects of e-cigarettes, particularly the contribution to the development of arrhythmias and cardiomyopathy. Evidence was synthesized from in vitro, animal models, and clinical research that covers e-cigarette constituents, delivery mechanisms of toxins, and both acute and chronic cardiovascular effects. E-liquid constituents can result in an autonomic imbalance, increasing heart rate and pressure, conductivity, and the predisposition of arrhythmias and cardiomyopathies. Recent research has shown oxidative stress, endothelial dysfunction, and autonomic imbalance instigated by nicotine and non-nicotinic additives, which destabilize cardiac electrophysiology. However, most human data remain short-term, with limited sample sizes and heterogeneous exposure assessment, underscoring the lack of longitudinal evidence on long-term outcomes such as myocardial infarction, heart failure, or sudden cardiac death. The clinical and public health implications are significant, and it is imperative to shift the focus to vaping as a separate cardiovascular risk factor, particularly among young adults. To reduce the increasing burden of e-cigarette-related cardiovascular disease, preventive actions and enhanced monitoring must be prioritized.

Both impaired systolic function (mean difference of EF increase from 52.84% to 71.10%, <i>P</i> value is 0.004, FS increase from 26.39% to 39.38%, <i>P</i> value is 0.008) and damaged diastolic function (mean difference of IVRT decrease from 26.50 ms to 16.33 ms, <i>P</i> value is 0.025, E/A ratio increase from 0.91 to 1.22, <i>P</i> value is 0.07) were observed in the DCM group, whereas acupuncture enhanced cardiac function in mice with DCM. Cardiac fibrosis was alleviated in the PC6+ST36 group, accompanied by reduced expression of fibrosis-related genes (<i>Col1a1</i> family). Moreover, acupuncture inhibited cardiac apoptosis in mice with DCM to some extent.</p><p><strong>Conclusions: </strong>Acupuncture at Neiguan and Zusanli can improve heart function and myocardial hypertrophy by inhibiting cardiac apoptosis and fibrosis in mice with DCM.</p>","PeriodicalId":7427,"journal":{"name":"American journal of cardiovascular disease","volume":"16 3","pages":"125-141"},"PeriodicalIF":1.4,"publicationDate":"2026-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13389451/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148560438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
