ABSTRACT
To explore the association between sarcopenia (SAR) and long-term prognosis of patients with chronic heart failure (CHF) aged 70 years and over,182 CHF patients from January l,2012 to December 31,2014 were included in the present study.The patients were divided into the SAR group and the non-SAR group.The median follow-up period was 36 (3,57) months.The endpoint was any heart failure-related event (HFRE).There were significant differences in age,body mass index,hemoglobin,B-type natriuretic peptide,hypersensitive troponin T (hs-TnT),left ventricular ejection fraction (LVEF) and cardiac function class between the two groups (all P＜0.05).The Kaplan-Meier analysis showed that the survival time of the non-SAR patients was much longer than that of the SAR patients (P＜0.05).The multivariate Cox regression analysis indicated that SAR was an independent risk factor for HFRE suggesting a role of sarcopenia on long-term prognosis of patients with chronic heart failure.
ABSTRACT
Objective@#To evaluate the anthracyclines-induced cardiotoxicity in patients with early-stage breast cancer.@*Methods@#This retrospective study analyzed data of 64 patients (aged from 36 to 59 years old) with early-stage breast cancer after surgery. Patients were divided into ACT group (n=21), FAC group (n=19) and EC group (n=24). The NCI CTC 4.0 scores was used to evaluate the side effects at the time of 2 weeks, 4 weeks and 6 weeks after chemotherapy. Meanwhile, the level of cTnT, the incidence of abnormal electrocardiogram (ECG) and left ventricular ejection fraction (LVEF) were used to evaluate the anthracyclines-induced cardiotoxicity, the follow-up observation points were as follows: at the acute cardiotoxicity (time A), subacute cardiotoxicity (time B), 24 months after chemotherapy (time C), 36 months after chemotherapy (time D), 48 months after chemotherapy (time E), 60 months after chemotherapy (time F). The 3-years and 5-years overall survival and progress free disease survival among three groups were compared.@*Results@#The ages, clinical stage, the size of tumor, axillary lymph node positivity and Eastern Cooperative Oncology Group Scores were similar among three groups (P>0.05); the incidence of side effects level 4 was 0. The levels of cTnT in the three groups were significantly lower than those at the baseline and time points C, D, E and F (all P<0.05), and the levels of cTnT were significantly higher in EC group than in FAC and ACT group at the time points B, C, D, E and F (P<0.05); however, the incidence of abnormal ECG and LVEF was similar among the 3 groups (P>0.05). The 5-year overall survival was 95.2% (20/21) ,100% (19/19) and 95.8% (23/24) in ACT group, FAC group and EC group, respectively; 5-year progress free disease survival was 95.2% (20/21) ,94.7% (18/19) and 91.7% (22/24) in ACT group, FAC group and EC group, respectively (P>0.05) .@*Conclusions@#Patients with early-stage breast cancer after surgery could tolerate the anthracyclines-induced cardiotoxicity. Three chemotherapy schemes of ACT, FAC and EC, especially the EC protocol, could affect the myocardial damage. However, outcome is comparable among patients treated with above chemotherapy schemes in this patient cohort.
