Prevalence and prognostic implications of sarcopenia in older patients with coronary heart disease.

BACKGROUND: Sarcopenia is a progressive and generalized skeletal muscle disorder that is associated with an increased likelihood of adverse outcomes, including falls, fractures, physical disability, and mortality. However, there have been few systematic studies of the prevalence and prognostic values of sarcopenia in older patients with coronary heart disease (CHD). This study aimed to investigate the prevalence of sarcopenia in hospitalized older patients with CHD, and to prospectively evaluate the effect of sarcopenia on the short-term prognosis of these patients. METHODS: Patients aged ≥ 65 years, with the diagnosis of CHD from Peking Union Medical College Hospital between December 2017 and November 2018, were included. Sarcopenia was diagnosed according to consensus of the Asian Working Group for Sarcopenia in 2014. Follow-up items included unscheduled return visits, occurrence of major adverse cardiac and cerebral events (MACCE), and all-cause mortality. The MACCE-free survival curve of sarcopenic and non-sarcopenic older patients with CHD was estimated by the Kaplan-Meier method. Cox regression analysis was used to analyze the association between sarcopenia and an unscheduled return visits, MACCE, and all-cause mortality. RESULTS: A total of 345 older patients with CHD were enrolled in the study, with a median age of 74 years. Among the patients, 78 (22.6%) were diagnosed with sarcopenia. During the follow-up time, there were significantly more unscheduled return visits in sarcopenic patients than in non-sarcopenic patients (34.2% vs. 21.8%, χ2 = 4.418, P = 0.036), while there was no significant difference in the occurrence of MACCE (χ2 = 2.869, P = 0.09) or all-cause mortality (χ2 = 1.673, P = 0.196) between these patient groups. The Kaplan-Meier curve showed that the MACCE-free survival time of sarcopenic patients was significantly shorter than that in non-sarcopenic patients (χ2 = 4.102, P = 0.043). After adjusting for sex, age, and the Charlson comorbidity index, sarcopenia was not an independent risk factor of unscheduled return visits (HR = 1.002, 95% CI: 0.556-1.807). However, the complication of anxiety and depression was an independent risk factor (HR = 1.876, 95% CI: 1.012-3.477, P = 0.046) for unscheduled return visits in older patients with CHD. CONCLUSIONS: There is a high prevalence of sarcopenia among hospitalized older adults with CHD. A shorter MACCE-free survival time and more unscheduled return visits are found in sarcopenic older patients with CHD. Clinicians should pay more attention to the functional status of older patients with CHD, as well as identification and management of geriatric syndromes.

Attitudes Toward Advance Directives Among Patients and Their Family Members in China.

OBJECTIVES: Chinese people are generally unfamiliar with the concept of advance care planning or advance directives (ACP/ADs), which raises dilemmas in life-support choice and can even affect clinical decision making. To understand and address the issues involved better, we investigated the awareness of ACP/ADs in China, as well as people's attitudes toward medical autonomy and end-of-life care. DESIGN: A multicenter cross-sectional survey, conducted from August 1 to December 31, 2016. SETTING: Twenty-five hospitals located in 15 different provinces throughout mainland China. PARTICIPANTS: Pairs of adult patients without dementia or malignancies, and a family member. MEASUREMENTS: Participants self-filled anonymous questionnaires, and the data collected were analyzed to relate patients' sociodemographic characteristics to their awareness of ACP/ADs and attitudes to health care autonomy and end-of-life care. RESULTS: Among 1084 patients who completed the questionnaire, 415 (38.3%) had heard about ACP/ADs. Having been informed about ACP/ADs, 995 (91.8%) were willing to find out their true health status and decide for themselves; 549 (50.6%) wanted to institute ACP/ADs. Regarding end-of-life care, 473 (43.6%) chose Do Not Resuscitate, and 435 (40.1%) wished to forgo life-support treatment if irreversibly moribund. Patients predominantly (481, 44.4%) chose general hospital as their preferred place to spend their last days of life; only 114 (10.5%) favored a special hospice facility. Patients' main concerns during end-of-life care were symptom control (35.1%), followed by functional maintenance and quality of life (29.8%), and prolonging life (18.9%). More highly educated patients had significantly greater awareness of ACP/ADs than less well educated ones (χ2 = 59.22, P < .001) and were more willing to find out the truth for themselves (χ2 = 58.30, P ≤ .001) and make medical decisions in advance (χ2 = 55.92, P < .001). Younger patients were also more willing than older ones to know the truth (χ2 = 38.23, P = .001) and make medical decisions in advance (χ2 = 18.42, P = .018), and were also more likely to wish to die at home (χ2 = 96.25, P < .001). Only 212 patients' family members (19.6%) wanted life-support treatment for themselves if irreversibly moribund, whereas 592 (54.6%) would want their relative to receive such procedures in the same circumstances; a similar discrepancy was evident for end-of-life invasive treatment (18.3% vs 42.7%). CONCLUSIONS: Awareness about ACP/ADs in China is still low. Providing culturally sensitive knowledge, education, and communication regarding ACP/ADs is a feasible first step to promoting this sociomedical practice.

Attitudes towards Advance Care Planning and Healthcare Autonomy among Community-Dwelling Older Adults in Beijing, China.

OBJECTIVES: To investigate the preferences of ACP and healthcare autonomy in community-dwelling older Chinese adults. METHODS: A community-based cross-sectional study was conducted with older adults living in the residential estate of Chaoyang District, Beijing. RESULTS: 900 residents were enrolled. 80.9% of them wanted to hear the truth regarding their own condition from the physician; 52.4% preferred to make their own healthcare decisions. Only 8.9% of them preferred to endure life-prolonging interventions when faced with irreversible conditions. 78.3% of the respondents had not heard of an ACP; only 39.4% preferred to document in an ACP. Respondents with higher education had significantly higher proportion of having heard of an ACP, as well as preferring to document in an ACP, compared to those with lower education. Those aged <70 years had higher proportion of having heard of an ACP, as well as refusing life-prolonging interventions when faced with irreversible conditions, compared to those aged ≥ 70 years. CONCLUSIONS: Although the majority of community-dwelling older Chinese adults appeared to have healthcare autonomy and refuse life-prolonging interventions in terms of end-of-life care, a low level of "Planning ahead" awareness and preference was apparent. Age and education level may be the influential factors.

Is frailty associated with short-term outcomes for elderly patients with acute coronary syndrome?

BACKGROUND: Frailty is a new prognostic factor in cardiovascular medicine due to the aging and increasingly complex nature of elderly patients. It is useful and meaningful to prospectively analyze the manner in which frailty predicts short-term outcomes for elderly patients with acute coronary syndrome (ACS). METHODS: Patients aged ≥ 65 years, with diagnosis of ACS from cardiology department and geriatrics department were included from single-center. Clinical data including geriatrics syndromes were collected using Comprehensive Geriatrics Assessment. Frailty was defined according to the Clinical Frailty Scale and the impact of the co-morbidities on risk was quantified by the coronary artery disease (CAD)-specific index. Patients were followed up by clinical visit or telephone consultation and the median follow-up time is 120 days. Following-up items included all-cause mortality, unscheduled return visit, in-hospital and recurrent major adverse cardiovascular events. Multivariable regression survival analysis was performed using Cox regression. RESULTS: Of the 352 patients, 152 (43.18%) were considered frail according to the study instrument (5-7 on the scale), and 93 (26.42%) were considered moderately or severely frail (6-7 on the scale). Geriatrics syndromes including incontinence, fall history, visual impairment, hearing impairment, constipation, chronic pain, sleeping disorder, dental problems, anxiety or depression, and delirium were more frequently in frail patients than in non-frail patients (P = 0.000, 0.031, 0.009, 0.014, 0.000, 0.003, 0.022, 0.000, 0.074, and 0.432, respectively). Adjusted for sex, age, severity of coronary artery diseases (left main coronary artery lesion or not) and co-morbidities (CAD specific index) by Cox survival analysis, frailty was found to be strongly and independently associated with risk for the primary composite outcomes: all-cause mortality [Hazard Ratio (HR) = 5.393; 95% CI: 1.477-19.692, P = 0.011] and unscheduled return visit (HR = 2.832; 95% CI: 1.140-7.037, P = 0.025). CONCLUSIONS: Comprehensive Geriatrics Assessment and Clinical Frail Scale were useful in evaluation of elderly patients with ACS. Frailty was strongly and independently associated with short-term outcomes for elderly patients with ACS.
