ObjectiveTo evaluate the impact of yang-reinforcing and blood-activating therapy on the long-term prognosis for patients with dilated cardiomyopathy (DCM) of yang deficiency and blood stasis syndrome. MethodsA retrospective cohort study was conducted involving 371 DCM patients with yang deficiency and blood stasis syndrome. The yang-reinforcing and blood-activating therapy was defined as the exposure factor. Patients were categorized into exposure group (186 cases) and non-exposure group (185 cases) according to whether they received yang-reinforcing and blood-activating therapy combined with conventional western medicine for 6 months or longer. The follow-up period was set at 48 months, and the Kaplan-Meier survival analysis was used to assess the cumulative incidence of major adverse cardiovascular events (MACE) in both groups. Cox regression analysis was used to explore the impact of yang-reinforcing and blood-activating therapy on the risk of MACE, and subgroup analysis was performed. Changes in traditional Chinese medicine (TCM) syndrome score, left ventricular ejection fraction (LVEF), left ventricular fractional shortening (LVFS), left ventricular end-diastolic diameter (LVEDD), and Minnesota Living with Heart Failure Questionnaire (MLHFQ) score were compared between groups at the time of first combined use of yang-reinforcing and blood-activating therapy (before treatment) and 1 year after receiving the therapy (after treatment). ResultsMACE occurred in 31 cases (16.67%) in the exposure group and 47 cases (25.41%) in the non-exposure group. The cumulative incidence of MACE in the exposure group was significantly lower than that in the non-exposure group [HR=0.559, 95%CI(0.361,0.895), P=0.014]. Cox regression analysis showed that yang-reinforcing and blood-activating therapy was an independent factor for reducing the risk of MACE in DCM patients [HR=0.623, 95%CI(0.396,0.980), P=0.041], and consistent results were observed in different subgroups. Compared with pre-treatment, the exposure group showed decreased TCM syndrome score and MLHFQ score, reduced LVEDD, and increased LVEF and LVFS after treatment (P<0.05); in the non-exposure group, TCM syndrome score decreased, LVEF and LVFS increased, and LVEDD reduced after treatment (P<0.05). After treatment, the exposure group had higher LVEF and LVFS, smaller LVEDD, and lower TCM syndrome score and MLHFQ score compared with the non-exposure group (P<0.05). ConclusionCombining yang-reinforcing and blood-activating therapy with conventional western medicine can reduce the risk of MACE in DCM patients with yang deficiency and blood stasis syndrome, meanwhile improving their clinical symptoms, cardiac function, and quality of life.

Objective To analyze the correlation between hemoglobin(Hb),anemia,and sarcopenia in the elderly population in Chongqing communities.Methods A cross-sectional study was conducted on elderly individuals who underwent healthy examinations at 5 community health service centers in Chongqing from March to August 2023.Demographic characteristics,social factors,body composition measurement,grip strength,6-meter gait speed and blood tests were assessed.Receiver operating characteristic(ROC)curve was utilized to evaluate the accuracy of Hb in predicting sarcopenia,and the Youden index was employed to determine the optimal Hb cut-off value for diagnosing sarcopenia and its components.Both unadjusted and adjusted logistic regression analyses were performed to examine the relationship between Hb and anemia with sarcopenia and its components.Results A total of 531 elderly populations were included,with an average age of(71.1±6.5)years.The overall prevalence of sarcopenia was 13.6%(72/531),including 29 males(40.3%)and 43 females(59.7%).Unadjusted analyses showed that Hb was correlated with sarcopenia,decreased muscle mass,slower gait speed,and reduced grip strength(P<0.05).After adjusting for all potential risk factors,Hb was still significantly associated with sarcopenia and reduced grip strength(P<0.05).For every 10 g/L increase in Hb,the risk of sarcopenia decreased by 2.3%,and the risk of reduced grip strength decreased by 1.7%(P<0.05).Anemia was correlated with sarcopenia,reduced muscle mass,and decreased grip strength in unadjusted analyses(P<0.05),while the correlation between anemia and reduced grip strength remained significant after adjustment for all potential risk factors(P<0.05).The optimal Hb cut-off value for diagnosing sarcopenia in males and females were 148 g/L and 128 g/L,respectively.Conclusions Hb is an independent risk factor for sarcopenia and reduced grip strength.Anemia is associated with sarcopenia,but is not an independent risk factor for sarcopenia.
