The implication of Torquetenovirus (TTV) in Ischemic Heart Disease (IHD) has not been thoroughly explored. This study investigated the association between TTV viremia, proinflammatory cytokines, and IHD risk in an aging population. This cross-sectional study included 900 non-IHD subjects (NIHD) and 86 individuals with IHD (aged 55 to 75 years) selected from the MARK-AGE project. Results were verified in another independent Report-Age cohort, including 94 inpatients with chronic IHD and 111 inpatients with no evidence of IHD (NIHD) (aged 65 to 96 years). Multivariable logistic regression in the MARK-AGE cohort revealed that male sex, TTV viremia ≥4log, Cu/Zn ratio, diabetes, hypertension and smoking were significant IHD predictors. Notably, TTV viremia ≥4log independently increased the IHD risk (OR: 2.51, 95% CI: 1.42-4.43), confirmed in the Report-Age cohort (OR: 4.90, 95% CI: 2.32-10.39). In a RASIG subgroup, individuals with TTV viremia ≥4log, both with and without IHD, exhibited increased plasma pro-inflammatory cytokine levels (IFN-γ, IL-1β, IL-6, IL-10, IL-12p70, TNF-α) compared to those with TTV viremia < 4log. No significant difference in cytokine production was observed between IHD patients and NIHD with TTV viremia ≥4log. A positive correlation between TTV viremia and DNA methylation estimator of leukocyte telomere length was observed in Report-Age patients. Additionally, IHD Report-Age patients with TTV viremia ≥4log displayed higher NLR and SIRI index than those with TTV viremia < 4log. In conclusion, a high TTV viremia is associated with an elevated IHD risk in the older population, potentially arising from an augmented proinflammatory response and immunosenescence

TTV 病毒血症、慢性炎症和缺血性心脏病风险之间的关联:来自 MARK-AGE 和 Report-AGE 项目的见解



Torquetenovirus (TTV) 在缺血性心脏病 (IHD) 中的影响尚未得到彻底探索。本研究调查了老龄化人群中 TTV 病毒血症、促炎细胞因子和 IHD 风险之间的关联。这项横断面研究包括从 MARK-AGE 项目中选出的 900 名非 IHD 受试者 (NIHD) 和 86 名 IHD 患者(年龄 55 至 75 岁)。结果在另一个独立的报告年龄队列中得到验证,包括 94 名慢性 IHD 住院患者和 111 名无 IHD 证据 (NIHD) 的住院患者 (年龄 65 至 96 岁)。MARK-AGE 队列中的多变量 logistic 回归显示,男性、 TTV 病毒血症 ≥4log、Cu/Zn 比值、糖尿病、高血压和吸烟是显著的 IHD 预测因子。值得注意的是,TTV 病毒血症 ≥4log 独立增加了 IHD 风险 (OR: 2.51,95% CI: 1.42-4.43),在报告年龄队列中得到证实 (OR: 4.90,95% CI: 2.32-10.39)。在 RASIG 亚组中,TTV 病毒血症 ≥4log,有和没有 IHD 的个体,血浆促炎细胞因子水平 (IFN-γ、IL-1β、IL-6、IL-10、IL-12p70、TNF-α) 与 TTV 病毒血症 < 4log 的个体相比。IHD 患者与患有 TTV 病毒血症的 NIHD 患者之间未观察到细胞因子产生的显着差异 ≥4log。在报告年龄患者中观察到 TTV 病毒血症与白细胞端粒长度的 DNA 甲基化估计器呈正相关。此外,TTV 病毒血症 ≥4log 的 IHD 报告年龄患者显示出比 TTV 病毒血症 < 4log 患者更高的 NLR 和 SIRI 指数。总之,高 TTV 病毒血症与老年人群 IHD 风险升高相关,这可能是由于促炎反应和免疫衰老增强引起的
