Methods In this study, we enrolled 103 patients aged 75 years or older with chronic angina in which 47 patients were assigned coronary angiography and revascularisation and 56 patients with optimised medical therapy. The primary endpoint was quality of life after 6 months, as assessed by questionnaire and the presence of major adverse cardiac events (death, non fatal myocardial infarction, or hospital admission for acute coronary syndrome with or without the need for revascularisation). Results After 6 months follow up, angina severity decreased and measures of quality of life increased in both treatment groups( P <0.05 ); however, these improvements were significantly greater after revascularisation( P <0.01 ). Major adverse cardiac events occurred in 30 ( 53.6% ) of patients in the medical group and 9 ( 19.1% ) in the invasive group ( P <0.01 ).Conclusions Patients aged 75 years or older with angina benefit more from revascularisation than from optimised medical therapy in terms of symptom relief and quality of life. Therefore, these patients should be offered invasive assessment despite their high risk profile followed by revascularisation if feasible.展开更多

Methods · Forty-one patients with AML(aged 55-71 years) were randomly divided into two groups(Group HCAG and Group IA) between 2014 and 2016 for induction and consolidation therapy. Multivariate analysis was applied to identify prognostic factors for relapse-free survival(RFS). Results · A total of 29 patients(70.7%) achieved complete remission(CR). The estimated 2-year overall survival(OS) was 66.8% in Group HCAG and 75.4% in Group IA(P=0.913). The estimated 2-year RFS was 61.8% in Group HCAG and 49.1% in Group IA(P=0.411). Age remained as the unfavorable prognostic factor, leading to significant differences in OS and RFS. In addition, RFS was influenced by cytogenetic/molecular risk stratification. Conclusion · Although HCAG seemed not to particularly benefit the group, the dose reduction of anthracyclines may be applied in elderly patients with comparable short-time outcome. Furthermore, the introduction of homoharringtonine resulted in an improvement of treatment response for more than 20% compared with CAG regimen.展开更多
