Abstract
BACKGROUND Living alone as a proxy for social isolation has been considered to increase the risk of cardiovascular disease. We thus investigated the impact of living alone on mortality in acute myocardial infarction (AMI) patients. METHODS Subjects comprised 277 AMI patients who underwent percutaneous coronary intervention (PCI). Associations between all-cause and cardiac deaths after PCI and baseline characteristics including living alone and Global Registry of Acute Coronary Events (GRACE) risk score were assessed. RESULTS Eighty-three patients (30%) were living alone. Thirty patients died after PCI, including 20 cardiac deaths. Patients living alone showed higher incidences of both all-cause and cardiac deaths compared with patients not living alone (18% vs. 8%, P = 0.019 and 14% vs. 4%, P = 0.004). Multivariate Cox proportional hazards regression analysis models showed living alone [hazard ratio (HR), 2.60; 95% confidence interval (CI), 1.20-5.62; P = 0.016 and HR, 4.17; 95% CI, 1.60-10.84; P = 0.003] and GRACE risk score (HR, 1.02; 95% CI, 1.01-1.03; P = 0.003 and HR, 1.03; 95% CI, 1.01-1.04; P < 0.001) correlated significantly with all-cause and cardiac deaths. Cox proportional hazards modeling revealed that patients living alone with GRACE risk score ≥162 derived from the receiver-operating characteristic curve showed a significantly greater risk of all-cause death than patients not living alone with GRACE risk score <162 (HR 16.57; 95% CI 6.67-41.21; P < 0.001). CONCLUSION Among AMI patients, living alone represents an independent risk factor for all-cause and cardiac deaths after PCI, separate from GRACE risk score. Furthermore, AMI patients living alone with high GRACE risk scores may experience an additively increased risk of mortality after PCI.

Abstract
We aimed to examine the relationship of living arrangements (i.e., living alone or living with others) with background, clinical severity, preintervention culprit lesion plaque morphology, and clinical outcomes in patients with acute coronary syndrome (ACS). Among 1,683 consecutive patients with ACS, we retrospectively compared patients living alone ( n = 318) versus living with others ( n = 1,362). Optical coherence tomography (OCT) findings, which are high-resolution intracoronary imaging devices, were analyzed in patients with preintervention OCT and compared between patients living alone ( n = 174) versus those living with others ( n = 665). Older (median; 69 vs. 67 y, p = 0.046) and female (31 vs. 17%, p < 0.001) patients more frequently lived alone. Frequency of achieving a time interval of 6 hours or less from ACS onset to admission was lower in patients living alone (56 vs. 63%, p = 0.022). Clinical presentation was more severe in patients living alone (Killip II/III/IV; 27 vs. 22%, p = 0.029). Plaque morphology evaluated by OCT was similar between groups (plaque rapture; 48 vs. 48%, p = 0.171). Kaplan-Meier analyses revealed higher rates of cardiac mortality during 2-year follow-up period in patients living alone [13.9 vs. 8.5%, hazard ratio (HR) 1.604, 95% confidence interval (CI) 1.112-2.313, p = 0.010]. After traditional cardiovascular risk factors and clinical severity upon admission had been adjusted, living alone was an independent predictor of cardiac mortality in ACS patients (HR 1.582, 95% CI 1.056-2.371, p = 0.026). Living alone was independently associated with 2-year cardiacmortality in ACS patients after adjusting for background and presentation and might be unrelated to the development of atherosclerosis.

Abstract
To explore whether living alone could increase the risk of cardiovascular outcomes. We searched PubMed, EMBASE, and Web of Science from their inception to 5 October 2020. Cohort studies evaluating the relationship between living alone and cardiovascular outcomes were included. Subgroup analyses were conducted to explore which characteristics would affect the relationship. A total of 13 effect sizes obtained from 11 studies were included and spanned from 1993 to 2019, with 424,286 participants. This study found that living alone increased the risk of cardiovascular outcomes (HR = 1.22, 95% CI: 1.10-1.36, I2 = 80.3%, P = 0.000). In subgroup analyses, living alone increased the risk of cardiovascular outcomes in patients from Europe (HR = 1.37, 95% CI: 1.17-1.61, I2 = 76.2%, P = 0.000), but not increased in Asia (HR = 1.17, 95% CI: 0.83-1.66, I2 = 76.2%, P = 0.000) and multiple regions (HR = 1.02, 95% CI: 0.96-1.08, I2 = 0.0%, P = 0.738). For different cardiovascular outcomes, living alone has statistical significance in increasing the risk of cardiovascular mortality (HR = 1.23, 95% CI: 1.05-1.46, I2 = 84.0%, P = 0.000) and myocardial infarction (HR = 1.11, 95% CI: 1.02-1.21, I2 = 29.6%, P = 0.213). The risk of cardiovascular mortality in men was higher than women (HR = 1.52, 95% CI: 1.24-1.86 vs HR = 1.01, 95% CI: 0.85-1.20; P < 0.05 for interaction). Sensitivity analysis suggested that the results of the meta-analysis were robust. In conclusion, living alone could increase the risk of cardiovascular outcomes and men were more prone to cardiovascular mortality and myocardial infarction.

Abstract
OBJECTIVE This study aimed to conduct a systematic review and meta-analysis of associations between loneliness, social isolation, and living alone and risk of mortality among individuals with established cardiovascular disease. METHODS Five electronic databases were searched (MEDLINE [Ovid], PsycINFO, EMBASE, PubMed, and SCOPUS) from inception to November 25, 2021. In all, 35 studies were included in a narrative synthesis and, where appropriate, a meta-analytic evaluation using a random-effects model. RESULTS Living alone was associated with increased risk of all-cause mortality ( k = 15, n = 80,243, hazard ratio [HR] = 1.48, 95% confidence interval [CI] = 1.20-1.83, I2 = 83%), and meta-regressions found that the effects were stronger in studies from Europe and with longer follow-up. However, there was evidence of publication bias. Social isolation was associated with increased risk of all-cause mortality, measured both as a dichotomous variable ( k = 3, n = 2648, HR = 1.46, 95% CI = 1.08-2.04, I2 = 31%) and as a continuous variable ( k = 5, n = 2388, HR = 1.11, 95% CI = 1.02-1.24, I2 = 51%). Meta-analysis was not feasible for loneliness as exposure, but narrative synthesis of four studies suggested a tentative association between loneliness and increased risk of all-cause mortality. CONCLUSIONS Supporting public health concerns, our review finds that loneliness, social isolation, and living alone are associated with premature mortality among individuals with established cardiovascular disease. However, evidence of publication bias and large methodological differences across studies point to the need for more rigorous research.

Abstract
Background There is a lack of studies evaluating the association between living status and subsequent outcomes in patients with type 2 diabetes (T2DM). Objectives This study aimed to assess the association between living alone and the risk of all-cause mortality in T2DM patients. Methods We performed a secondary analysis in patients with long-lasting T2DM from the Action to Control Cardiovascular Risk in Diabetes (ACCORD) study. The primary outcome was all-cause mortality. Multivariable Cox proportional hazard models was used to analyze and compare the hazard ratios (HRs) in patients living alone and with one or more adults. Results This study included 10,249 patients with T2DM. Of these, 2,078 (20.28%) were living alone and 8,171 (79.72%) lived with one or more adults. Over a median total follow-up of 8.8 years, 1,958 patients developed the primary endpoint. The all-cause mortality rates in patients living alone or living with one or more adults were 23.24 and 18.05%, respectively. Cox proportional hazard analysis showed that T2DM patients living alone had significantly higher rate of all-cause mortality than those living with others (HR, 1.34; 95% confidence interval [CI], 1.20–1.48; p < 0.001). After multivariable adjustment, living alone was an independent risk factor for all-cause mortality in patients with T2DM (adjusted HR, 1.27; 95% CI, 1.14–1.41; p < 0.001). Furthermore, the risks of both congestive heart failure (CHF) and fatal coronary heart disease (CHD) among 4,050 propensity score-matched patients were higher for patients living alone (respectively HR, 1.37; 95% CI, 1.08–1.74; p = 0.010; and HR, 1.16; 95% CI, 1.00–1.34; p = 0.047). Conclusions The risk of all-cause mortality was significantly higher in T2DM patients living alone than in those living with one or more adults.

Abstract
AIMS Living alone is reported as an independent risk factor for cardiovascular disease. However, little is known about the association between clinical outcomes and living alone in patients with acute coronary syndrome (ACS). The aim of this study was to determine whether living alone is an independent prognostic risk factor for long-term mortality stratified by age in patients with ACS who were treated with primary percutaneous coronary intervention (PCI). METHODS AND RESULTS We conducted an observational cohort study of ACS patients who underwent PCI between January 1999 and May 2015 at Juntendo University Shizuoka Hospital, Japan. The primary endpoint was all-cause death. Among 2547 ACS patients, 381 (15.0%) patients were living alone at the onset of ACS. The cumulative incidence of all-cause death was comparable between living alone and living together (34.8% vs. 34.4%, log-rank P = 0.63). However, among younger population (aged <65 years), the incidence of all-cause death was significantly higher in the living alone group (log-rank P = 0.01). Multivariate Cox hazard analysis revealed a significant association between living alone and all-cause death, even after adjusting for other risk factors (hazard ratio 2.30, 95% confidence interval 1.38-3.84, P = 0.001). CONCLUSION Although living alone was not significantly associated with long-term clinical outcomes in patients with ACS, it was a predictive risk factor among younger ACS patients. Careful attention should be paid to patients' lifestyle, especially younger patients with ACS.

Abstract
Because living alone is associated with an increased risk of type 2 diabetes mellitus in men but not women, living alone may be a risk factor of cardiovascular events after acute myocardial infarction (AMI) in diabetic men. The aim of the present study was to investigate the association between living alone and mid-term clinical outcomes after AMI in diabetic men. We conducted a single center, retrospecitve study. The primary endpoint was the major adverse cardiovascular events (MACE) defined as the composite of all cause death, AMI, and target vessel revascularization. A total of 253 AMI men with diabetes mellitus were included from our hospital records, and divided into the living together group (n = 203) and the living alone group (n = 50). Median follow-up duration was 239 days (Q1: 94 days, Q3: 451 days). A total of 66 MACE was observed during the study period, and Kaplan-Meier curves were constructed to compare the MACE. The MACE was more frequently observed in the living alone group than the living together group (P = 0.041). Multivariate Cox regression analysis revealed that the living alone group was significantly associated with the MACE (Odds ratio: 1.770, 95% confidence interval 1.018-3.077, P = 0.043) after known clinical risk factors. In conclusion, living alone was significantly associated with the mid-term MACE after AMI in diabetic men. It may be important to provide multiple interventions including lifestyle guidance as well as sufficient acute medical care for such high-risk patients.

Abstract
ObjectiveTo evaluate cardiovascular (CV) outcomes in outpatients with coronary artery disease (CAD) living alone compared with those living with others.MethodsThe prospeCtive observational LongitudinAl RegIstry oF patients with stable coronarY artery disease (CLARIFY) included outpatients with stable CAD. CLARIFY enrolled participants in 45 countries from November 2009 to July 2010, with 5 years of follow-up. Living arrangement was documented at baseline. The primary outcome was a composite of major adverse cardiovascular events (MACEs) defined as CV death, myocardial infarction (MI) and stroke.ResultsAmong 32 367 patients, 3648 patients were living alone (11.3%). After multivariate adjustment, there were no residual differences in MACE among patients living alone compared with those living with others (HR 1.04, 95% CI 0.92 to 1.18, p=0.52); however, there was significant heterogeneity in the exposure effect by sex (Pinteraction<0.01). Specifically, men living alone were at higher risk for MACE (HR 1.17, 95% CI 1.002 to 1.36, p=0.047) as opposed to women living alone (HR 0.82, 95% CI 0.65 to 1.04, p=0.1), predominantly driven by a heterogeneous effect by sex on MI (Pinteraction=0.006). There was no effect modification for MACE by age group (Pinteraction=0.3), although potential varying effects by age for MI (Pinteraction=0.046) and stroke (Pinteraction=0.05).ConclusionsLiving alone was not associated with an independent increase in MACE, although significant sex-based differences were apparent. Men living alone may have a worse prognosis from CV disease than women; further analyses are needed to elucidate the mechanisms underlying this difference.Trial registration numberISRCTN43070564.

Abstract
To observe the effect of simvastatin in patients with acute myocardial infarction in rabbits against myocardial apoptosis, and to explore its possible mechanism. Male New Zealand white rabbits were randomized into three groups, including the myocardial infarction group (12 rabbits), the simvastatin treatment group (15 rabbits), and the sham group (12 rabbits). In the simvastatin treatment and myocardial infarction groups, the rabbits received myocardial infarction surgeries. While in the sham group, loose knots were tied in the left anterior descending coronary artery branches. The simvastatin treatment group was given simvastatin by oral gavage 24 h after surgery. Parameters, which included left ventricular end-diastolic diameter, left ventricular end-systolic diameter, left ventricular ejection fraction, and left ventricular mass index, were recorded in these three groups. Edge myocardial infarction and myocardial cell apoptosis were analyzed using TUNEL assay, and Bcl-2, Bax, and Caspase-3 protein levels were detected by Western blot. Acute myocardial infarction model was successfully established in rabbits by ligation of the left anterior descending coronary artery. Compared with the myocardial infarction group, left ventricular end-diastolic diameter (LVEDD) and left ventricular end systolic diameter (LVESD) were significantly reduced and left ventricular ejection fraction (LVEF) increased in the simvastatin treatment group. Compared with the sham group, LVEDD and LVESD were significantly increased and LVEF decreased in the simvastatin treatment group. All the differences were statistically significant (P < 0.05). Left ventricular mass index in the simvastatin treatment group was statistically lower than the myocardial infarction group. Compared with the sham group, left ventricular mass index in both the simvastatin treatment and myocardial infarction groups was significantly increased. The differences of the above comparisons were statistically significant (P < 0.05). Compared with the sham group, the apoptosis rate of the myocardial infarction group and the simvastatin treatment groups was significantly increased as shown by TUNEL assay, however, the apoptosis rate of the simvastatin treatment group was significantly lower than that of the myocardial infarction group. All the differences among above comparisons were statistically significant (P < 0.05). Bcl-2 levels significantly increased in the simvastatin treatment group compared with the myocardial infarction group, but Bcl-2 levels in both groups were significantly lower than the sham group. However, Bax protein levels showed inverse expression with Bcl-2. Meanwhile, Caspase-3 protein expression showed similar trend with Bcl-2. Simvastatin can improve cardiac function after myocardial infarction and reduce apoptosis of myocardial cells, possibly by decreasing Bax and Caspase-3 expression and increasing the expression level of Bcl-2.
