We analyzed health data from 182,008 male employees and their family members in South Korea between 2010 and 2019, categorizing participants by BMI and age. CAC, a validated marker of subclinical atherosclerosis and a predictor of cardiovascular events, was measured via multidetector computed tomography. In unadjusted analyses, overweight and obese individuals exhibited a significantly higher risk of CAC compared to those with underweight BMI. After adjusting for potential confounding factors, obesity remained independently associated with an increased risk of CAC, while the association with overweight was no longer significant. Age strongly influenced this relationship; individuals aged 70 years or older demonstrated a markedly higher CAC risk, but obesity's association with CAC was significant only in those aged 60 years or younger. These findings indicate that obesity, even in the absence of metabolic abnormalities, contributes to an increased risk of atherosclerosis in younger individuals, challenging the concept of \"metabolically healthy obesity.\" In conclusion, our results underscore the importance of targeted cardiovascular risk assessments that consider both BMI and age, highlighting the need for early intervention in younger adults with elevated BMI to prevent atherosclerosis and suggesting a distinct risk profile in older adults.</p>","PeriodicalId":7705,"journal":{"name":"American Journal of Cardiology","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143727528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, significant anatomical variability in Koch's triangle poses challenges for precise ablation and increases the risk of atrioventricular block (AVB). Previous studies have reported that the AVNsp visualization strategy reduces the incidence of AVB, however, these studies were conducted in pediatric patients or with the energy of cryoablation. However, the safety and effectiveness of this strategy in adults undergoing radiofrequency ablation (RFA) remains unclear. This study aimed to evaluate the safety and effectiveness of high-density mapping (HDM)-guided AVNsp visualization strategy for AVNRT ablation compared to the conventional approach. We retrospectively analyzed data from 149 AVNRT patients across three hospitals in China. Patients were divided into two groups: experimental group (i.e. treated with the HDM-guided AVNsp visualization strategy, n=88) and control group (i.e. treated with the traditional mapping and ablation strategy, n=61). Procedural parameters, complication rates, and long-term outcomes were compared. The experimental group required fewer ablation points (4.8±3.6 vs 8.5±7.7, P=0.003), shorter total ablation time (284±178s vs 408±345s, P=0.028), and reduced procedure time (41.4±14.2min vs 51.5±27.2min, P=0.009) compared with the control group. No cases of AVB occurred in the experimental group, while the control group reported 5(8.2%) transient AVB and 1(1.6%) persistent first-degree AVB after procedure. After a mean follow-up of 488±246 days, no recurrences of AVNRT were observed in either group. In conclusion, for adult patients with AVNRT, the AVNsp visualization strategy enhances the safety and effectiveness of RFA by reducing procedure time and minimizing the risk of AVB.</p>","PeriodicalId":7705,"journal":{"name":"American Journal of Cardiology","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143690453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The 16-year reconstructed analysis revealed that patients undergoing MVRep have higher survival compared to the MVR group (HR: 1.41, 95% Cl: 1.30-1.53, p < 0.001). Moreover, IE recurrence was significantly lower in MVRep (95% CI, RR:0.46, 12 = 41%, p = 0.03). Reoperation rates, however, were similar between MVRep and MVR (95% CI, RR: 0.78, 12 = 0%, p = 0.27).
