Methods We used retrospective data from our center between 2013 and 2017. During a median of 17.4 (interquartile range: 7.3–32.3) months follow-up, 120 deaths were recorded among 514 consecutive patients ≥ 80 years with AMI. The patients were divided into two groups: invasive treatment group (IT group, n = 269) and conservative treatment group (CT group, n = 245), which were also then compared with propensity score matching. Results High mortality was found in CT group compared with that in the IT one. Cox proportional hazard regression analysis showed that invasive treatment was associated with lower mortality of patients ≥ 80 years. Moreover, the results revealed that the patients in IT group had lower in-hospital mortality (3.35% vs. 9.39%, P = 0.005). Besides, the Kaplan-Meier analysis revealed that the mortality was significantly lower in IT group compared with that in CT group using entire and propensity-matched cohort analysis (P < 0.001, respectively). Conclusions Our data suggested that IT appeared to be associated with lower mortality in Chinese patients ≥ 80 years with AMI, which consists with previous studies in spite of either ST elevated myocardial infarction (STEMI) or non-STEMI (NSTEMI) patients.展开更多

Methods A total of 4206 euthyroid patients were consecutively enrolled and di- vided into CAD group （n = 3306） and non-CAD group （n = 900）. All patients underwent coronary angiography （CAG）. Gensini score （GS） was used to determine the severity of coronary artery stenosis. Severe CAD was defined as GS 〉 32 and mild CAD was defined as GS 〈 32. Logistic regression analysis and linear regression analysis were conducted to determine the association of FT3 with CAD in patients with different gender and ages. Results Concentration of FT3 was lower in patients with CAD than that in angiography-normal control group （P 〈 0.05）. In addition, concentration of FT3 was lower in severe CAD than that in mild CAD. After adjusting for traditional cardiovascular risk factors and potential confounders, FT3 was negatively correlated with the presence of CAD, but not in the old patients （〉 65 years old）. Mul- tivariable linear regression analysis showed that FT3 was negatively associated with GS in male and young patients with stable CAD, but not in the old patients. Conclusions Low FT3 within normal range was negatively associated with the presence and severity of CAD in young patients, but not in the old ones. Further studies are needed to confirm our findings.展开更多
