ObjectivesSerum calcium levels (sCa) were reported to be associated with risk of cardiovascular diseases. The aim of this study was to analyse the association between sCa and long-term mortality in patients with acute coronary syndrome (ACS).DesignA retrospective observational cohort study.SettingSingle-centre study with participants recruited from the local area.ParticipantsA total of consecutive 13 772 patients with ACS were included in this analysis. Patients were divided based on their sCa profile (≤2.1 mmol/L, 2.1–2.2 mmol/L, 2.2–2.3 mmol/L, 2.3–2.4 mmol/L, 2.4–2.5 mmol/L,>2.5 mmol/L) and followed up for a median of 2.96 years (IQR 1.01–4.07).Primary outcomeLong-term all-cause mortality.ResultsDuring a median follow-up period of 2.96 years, patients with sCa ≤2.1 mmol/L had the highest cumulative incidences of all-cause mortality (16.7%), whereas those with sCa 2.4–2.5 mmol/L had the lowest cumulative incidences of all-cause mortality (3.5%). After adjusting for potentially confounding variables, the Cox analysis revealed that compared with the reference group (sCa 2.4–2.5 mmol/L), all the other groups had higher mortality except for the sCa 2.3–2.4 mmol/L group (HR, 1.32, 95% CI 0.93 to 1.87). Restricted cubic splines showed that the relationship between sCa and all-cause mortality seemed to be U shaped. The optimal sCa cut-off point, 2.35 mmol/L, was determined based on the shape of restricted cubic splines.ConclusionsAltered serum calcium homeostasis at admission independently predicts all-cause mortality in patients with ACS. In addition, a U-shaped relationship between sCa and all-cause mortality exists, and maintaining sCa at approximately 2.35 mmol/L may minimise the risk of mortality.

ObjectivesThe objective of this study is to examine the temporal trend of antiplatelet prescribing pattern during index hospitalisation discharge in Hong Kong (HK) acute coronary syndrome (ACS) population.DesignThe study is a retrospective observational cohort study.SettingThe study retrieved data from electronic health record from Hospital Authority (HA), HK.ParticipantsThe study included patients aged 18 years old or above, who were admitted to seven institutions under HA with diagnosis of ACS during 2008–2017.Primary and secondary outcome measuresThe primary outcome was the frequency of antiplatelet therapy prescription at the point of index hospitalisation discharge each year during 2008–2017. Association between demographics, baseline comorbidities, procedures and antiplatelet prescription were examined as secondary outcome using multivariate logistic regression model, with commonly used antiplatelet groups selected for comparison.ResultsAmong the included 14 716 patients, 5888 (40.0%) discharged with aspirin alone, 6888 (46.8%) discharged with dual antiplatelet therapy (DAPT) with clopidogrel, and 973 (6.6%) discharged with DAPT with prasugrel/ticagrelor. Prescribing rate of aspirin alone decreased substantially from 56.8% in 2008 to 27.5% in 2017. Utilisation of DAPT with clopidogrel increased from 33.7% in 2008 to 52.7% in 2017. Use of DAPT with prasugrel/ticagrelor increased from 0.3% in 2010 to 15.3% in 2017. Compared with those prescribed with DAPT with clopidogrel, male patients (adjusted OR (aOR) 1.34, 95% CI 1.09 to 1.65), patients with non-ST-elevation myocardial infarction (aOR 2.50, 1.98 to 3.16) or ST-elevation myocardial infarction (aOR 3.26, 2.59 to 4.09), use of glycoprotein IIb/IIIa (aOR 3.03, 2.48 to 3.68) or undergoing percutaneous coronary intervention (aOR 3.85, 3.24 to 4.58) or coronary artery bypass graft (aOR 6.52, 4.63 to 9.18) during index hospitalisation, concurrent use of histamine-2 receptor antagonists (aOR 1.35, 1.10 to 1.65) or proton pump inhibitors (aOR 3.57, 2.93 to 4.36) during index hospitalisation discharge were more likely to be prescribed with DAPT with prasugrel/ticagrelor. Patients with older age (aOR 0.97, 0.96 to 0.97), diabetes (aOR 0.68, 0.52 to 0.88), chronic kidney disease (aOR 0.43, 0.22 to 0.85) or concurrent use of oral anticoagulant (aOR 0.16, 0.07 to 0.42) were more likely to received DAPT with clopidogrel.ConclusionsUse of DAPT with prasugrel/ticagrelor was suboptimal yet improving during 2008–2017 in HK patients with ACS. Considering DAPT, predictors for clopidogrel prescription, compared with prasugrel/ticagrelor, were consistent with identified risk factors of bleeding.

Abstract Background With the advancement of the world population aging, more attention should be paid to the prognosis of elderly patients with acute coronary syndrome (ACS). Triglyceride-glucose (TyG) index is a reliable indicator of insulin resistance (IR) and is closely related to traditional risk factors of cardiovascular disease (CVD). However, the effect of TyG index on the prognosis of long-term adverse events in elderly ACS patients has not been reported. This study evaluated the prognostic power of TyG index in predicting adverse events in elderly ACS patients. Methods In this study, 662 ACS patients > 80 years old who were hospitalized from January 2006 to December 2012 were enrolled consecutively and the general clinical data and baseline blood biochemical indicators were collected. The follow-up time after discharge was 40–120 months (median, 63 months; interquartile range, 51‒74 months). In addition, the following formula was used to calculate the TyG index: Ln [fasting TG (mg/dL) × FBG (mg/dL)/2], and patients were divided into three groups according to the tertile of the TyG index. Results The mean age of the subjects was 81.87 ± 2.14 years, the proportion of females was 28.10%, and the mean TyG index was 8.76 ± 0.72. The TyG index was closely associated with the traditional risk factors of CVD. In the fully-adjusted Cox regression model, the Hazard ratio (95% CI) of all-cause mortality (in tertile 3) was 1.64 (1.06, 2.54) and major adverse cardiac event (MACE) (in tertile 3) was 1.36 (1.05, 1.95) for each SD increase in the TyG index. The subgroup analyses also confirmed the significant association of the TyG index and long-term prognosis. Conclusion The TyG index is an independent predictor of long-term all-cause mortality and MACE in elderly ACS patients.

Background: Hostility is associated with greater risk for cardiac disease, cardiac events and dysrhythmias. Investigators have reported equivocal findings regarding the association of hostility with acute coronary syndrome (ACS) recurrence and mortality. Given mixed results on the relationship between hostility and cardiovascular outcomes, further research is critical. Aims: The aim of our study was to determine whether hostility was a predictor of ACS recurrence and mortality. Methods: We performed a secondary analysis of data ( N = 2321) from a large randomized clinical trial of an intervention designed to reduce pre-hospital delay among patients who were experiencing ACS. Hostility was measured at baseline with the Multiple Adjective Affect Checklist (MAACL) and patients were followed for 24 months for evaluation of ACS recurrence and all-cause mortality. We used Cox proportional hazards modeling to determine whether hostility was predictive of time to ACS recurrence or all-cause mortality. Results: The majority of patients were married (73%), Caucasian (97%), men (68%), and had a mean age of 67 ± 11 years. Fifty-seven percent of participants scored as hostile based on the established MAACL cut point (mean score = 7.56 ± 3.8). Hostility was an independent predictor of all-cause mortality ( p = < 0.039), but was not a predictor of ACS recurrence ( p = 0.792). Conclusion: Hostility is common in patients with ACS and its relationship to clinical outcomes is important to the design of future interventions to improve long-term ACS mortality.

ObjectiveWe aimed to describe the association between in-hospital infection and prognosis among patients with non-ST elevation acute coronary syndrome (NSTE-ACS) who received percutaneous coronary intervention (PCI).DesignThis observational cohort originated from a database of patients with NSTE-ACS who underwent PCI from 1 January 2010 to 31 December 2014.SettingFive centres in South China.ParticipantsThis multicentre observational cohort study consecutively included 8197 patients with NSTE-ACS who received PCI. Only patients with adequate information to diagnose or rule out infection were included. Patients were excluded if they were diagnosed with a malignant tumour, were pregnant or presented with cardiogenic shock at the index date. Patients were grouped by whether they had in-hospital infection or not.Primary and secondary outcome measuresThe primary outcome was all-cause death and major bleeding during hospitalisation. The secondary outcomes included all-cause death and major bleeding during follow-up and in-hospital myocardial infarction.ResultsOf the 5215 patients, 206 (3.95%) acquired infection. Patients with infection had a higher rate of in-hospital all-cause death and major bleeding (4.4% vs 0.2% and 16.5% vs 1.2%, respectively; p<0.001). After adjusting for confounders, infection remained independently associated with in-hospital and long-term all-cause death (OR, 13.19, 95% CI 4.59 to 37.87; HR, 2.03, 95% CI 1.52 to 2.71; p<0.001) and major bleeding (OR, 10.24, 95% CI 6.17 to 16.98; HR, 5.31, 95% CI 3.49 to 8.08; p<0.001). A subgroup analysis confirmed these results.ConclusionsThe incidence of infection is low during hospitalisation, but is associated with worse in-hospital and long-term outcomes.

ObjectivesTo evaluate the frequency, clinical and etiologic features, and short- and long-term outcomes of early recurrent TIA.MethodsThis prospective observational cohort study enrolled all consecutive patients with TIA referred to our emergency department and diagnosed by a vascular neurologist. Expedited assessment and best secondary prevention were performed within 24 hours. Primary endpoints were stroke and a composite outcome including stroke, acute coronary syndrome, and vascular death at 3, 12, and, for a subset of patients, 60 months; secondary outcomes were TIA relapse, cerebral hemorrhage, new-onset atrial fibrillation, and death resulting from other causes. Concordance between index TIA and subsequent stroke etiologies was also evaluated.ResultsA total of 1,035 patients (822 with a single TIA, 213 with recurrent TIA = 21%) were enrolled from August 2010 to December 2017. Capsular warning syndrome and large artery atherosclerosis showed the strongest relationship with early recurrent TIA. The risk of stroke was significantly higher in the early recurrent TIA subgroup at each follow-up, and most stroke episodes occurred within 48 hours of index TIA. TIAs with lesion, dysarthria, and leukoaraiosis were the 3- and 12-month independent predictors of stroke incidence after early recurrent TIA subgroup. Index TIA and subsequent stroke etiologies showed substantial concordance. An ABCD3 score >6 predicted a higher risk of stroke recurrence over the entire follow-up.ConclusionsOur study evaluated long-term outcome after early recurrent TIA. Our observations support the importance of promptly detecting and treating patients with early recurrent TIAs to reduce the high early and long-term risk of poor clinical outcomes.
