Abstract
AIM AND OBJECTIVES To examine the dissimilarity between Chinese myocardial infarction (MI) patients' and spouses' illness perceptions (IPs), and to explore the relationship between patients' IP, differences in couples' IP and patients' lifestyle after discharge. BACKGROUND An individual's IP is affected and moderated by several factors, including the social context. One of the most influential members of the social network of patients is the spouse. DESIGN Cross-sectional design. METHODS From April 2016-April 2017, 111 MI patients and their spouses were recruited. Before discharge from hospital, revised Illness Perception Questionnaire was administered to MI patients and their spouses separately. Two months after discharge, patients' lifestyle was assessed using Health Promoting Lifestyle Profile II. The manuscript was organised according to STROBE guidelines. RESULTS Spouses were more likely to believe that the illness would last for a long time, and patients perceived MI as being more controllable than their spouses did. The patient-spouse dissimilarity in the perception of consequences was negatively correlated with both nutrition and stress control behaviours. Patients in couples with more dissimilar perception of environmental factors as a cause were more likely to choose a healthy diet, while patients in couples with more dissimilar perceived treatment control were more able to control stress. CONCLUSION There are both similarities and dissimilarities between MI patients' and spouses' IP, and these dissimilarities contributed the majority of the explained variance in patients' lifestyle after discharge. RELEVANCE TO CLINICAL PRACTICE We should consider both couples when examining how a patient copes with a chronic illness.

Abstract
High-density lipoprotein (HDL) is highly heterogeneous in its size and composition. Till now, the link of HDL subfractions to coronary risk is less clear. We aimed to investigate the associations of HDL subfractions with traditional risk factors (RFs), coronary severity, and outcomes in a cohort of nontreated patients with stable coronary artery disease (CAD). We prospectively enrolled 591 eligible patients. Baseline HDL subfractions were separated by Lipoprint system. HDL subfractions (large, medium, and small) and HDL-cholesterol (HDL-C) levels were dichotomized into low and high group according to the 50 percentile. Coronary severity was evaluated by SYNTAX, Gensini, and Jeopardy scoring systems. Patients were followed up annually for major adverse cardiovascular events (MACEs). Cox proportional hazards' models were used to evaluate the risk of HDL subfractions on MACEs. Patients with high large HDL-C levels had a decreased number of RFs. Significantly, large HDL-C levels were negatively associated with coronary severity assessed by SYNTAX and Gensini score (both P < 0.05). New MACEs occurred in 67 (11.6%) patients during a median 17.0 months follow-up. Moreover, the log-rank test revealed that there was a significant difference between high and low large HDL-C groups in event-free survival analysis (P = 0.013), but no differences were observed in total HDL-C groups and medium or small HDL-C groups (both P > 0.05). In particular, the multivariate Cox-proportional hazards model revealed that high large HDL-C was associated with lower MACEs risk (hazard ratio [95% confidence interval] 0.531 [0.295-0.959]) independent of potential confounders. Higher large HDL-C but not medium, small, or total HDL-C is associated with lower cardiovascular risk, highlighting the potential beneficial of HDL subfractionation.

Abstract
INTRODUCTION Most studies on intracoronary bone marrow mononuclear cell transplantation for acute myocardial infarction involve treatment 3-7 days after primary percutaneous coronary intervention (PCI); however, the optimal timing is unknown. The present study assessed the therapeutic effect at different times after ST-elevation myocardial infarction. METHODS The present trial was not blinded. A total of 104 patients with a first ST-elevation myocardial infarction and a left ventricular ejection fraction below 50 %, who had PCI of the infarct-related artery, were randomly assigned to receive intracoronary infusion of bone marrow mononuclear cells within 24 hours (group A, n = 27), 3 to 7 days after PCI (group B, n = 26), or 7 to 30 days after PCI (group C, n = 26), or to the control group (n = 25), which received saline infusion performed immediately after emergency PCI. All patients in groups A, B and C received an injection of 15 ml cell suspension containing approximately 4.9 × 10(8) bone marrow mononuclear cells into the infarct-related artery after successful PCI. RESULTS Compared to control and group C patients, group A and B patients had a significantly higher absolute increase in left ventricular ejection fraction from baseline to 12 months (change: 3.4 ± 5.7 % in control, 7.9 ± 4.9 % in group A, 6.9 ± 3.9 % in group B, 4.7 ± 3.7 % in group C), a greater decrease in left ventricular end-systolic volumes (change: -6.4 ± 15.9 ml in control, -20.5 ± 13.3 ml in group A, -19.6 ± 11.1 ml in group B, -9.4 ± 16.3 ml in group C), and significantly greater myocardial perfusion (change from baseline: -4.7 ± 5.7 % in control, -7.8 ± 4.5 % in group A, -7.5 ± 2.9 % in group B, -5.0 ± 4.0 % in group C). Group A and B patients had similar beneficial effects on cardiac function (p = 0.163) and left ventricular geometry (left ventricular end-distolic volume: p = 0.685; left ventricular end-systolic volume: p = 0.622) assessed by echocardiography, whereas group C showed similar results to those of the control group. Group B showed more expensive care (p < 0.001) and longer hospital stays during the first month after emergency PCI (p < 0.001) than group A, with a similar improvement after repeat cardiac catheterization following emergency PCI. CONCLUSION Cell therapy in acute myocardial infarction patients that is given within 24 hours is similar to 3-7 days after the primary PCI. TRIAL REGISTRATION NCT02425358 , registered 30 April 2015.
