AbstractDespite the known association of cardiac rupture with acute myocardial infarction (AMI), it is still unclear whether the clinical characteristics are associated with the risk of in-hospital mortality in patients with AMI complicated by cardiac rupture. The purpose of this study was to investigate the association between the time of cardiac rupture occurrence and the risk of in-hospital mortality after AMI. We conducted a retrospective analysis of multicenter registry data from eight medical universities in Eastern Japan. From 10,278 consecutive patients with AMI, we included 183 patients who had cardiac rupture after AMI, and examined the incidence of in-hospital deaths during a median follow-up of 26 days. Patients were stratified into three groups according to the AMI-to-cardiac rupture time, namely the > 24-h group (n = 111), 24–48-h group (n = 20), and < 48-h group (n = 52). Cox proportional hazards regression analysis was used to estimate the hazard ratio (HR) and the confidence interval (CI) for in-hospital mortality. Around 87 (48%) patients experienced in-hospital death and 126 (67%) underwent a cardiac surgery. Multivariable Cox regression analysis revealed a non-linear association across the three groups for mortality (HR [CI]; < 24 h: 1.0, reference; 24–48 h: 0.73 [0.27–1.86]; > 48 h: 2.25 [1.22–4.15]) after adjustments for age, sex, Killip classification, percutaneous coronary intervention, blood pressure, creatinine, peak creatine kinase myocardial band fraction, left ventricular ejection fraction, and type of rupture. Cardiac surgery was independently associated with a reduction in the HR of mortality (HR [CI]: 0.27 [0.12–0.61]) and attenuated the association between the three AMI-to-cardiac rupture time categories and mortality (statistically non-significant) in the Cox model. These data suggest that the AMI-to-cardiac rupture time contributes significantly to the risk of in-hospital mortality; however, rapid diagnosis and prompt surgical interventions are crucial for improving outcomes in patients with cardiac rupture after AMI.

Abstract Background The benefit of statins in secondary prevention of patients stabilized after acute coronary syndrome (ACS) has been well established. However, the benefit of preloading statins, i.e. high-intensity statins prior to reperfusion therapy remains unclear. Most previous studies included all types of ACS patients, and subgroup analysis indicated the benefit of preloading statins was only seen in ST-elevation myocardial infarction (STEMI) patients who underwent percutaneous coronary intervention (PCI). However, the sample size of subgroup population was relatively small and such benefit requires further validation. Objective To investigate the effect of loading dose of statins before primary reperfusion on 30-mortality in patients with STEMI. Methods We enrolled patients in China Acute Myocardial Infarction (CAMI) registry from January 2013 to September 2014. CAMI registry was a prospective multicenter registry of patients with acute acute myocardial infarction in China. Patients were divided into two groups according to statins usage: preloading group and control group. Patients in preloading group received loading does of statins before primary reperfusion and during hospitalization. Patients in control group did not receive statins during hospitalization or at discharge. Primary outcome was in-hospital mortality. Baseline characteristics, angiographic characteristics and outcome were compared between groups. Propensity score (PS) matching was used to mitigate baseline differences between groups and examine the association between preloading statins on in-hospital mortality risk. The following variables were used to establish PS matching score: age, sex, classification of hospitals, clinical presentation (heart failure at presentation, cardiac shock, cardiac arrest, Killip classification), hypertension, diabetes, prior angina, prior myocardial infarction history, prior stroke, initial treatment. Results A total of 1169 patients were enrolled in control group and 6795 in preloading group. A total of 833 patients (334 in control group and 499 in preloading group) died during hospitalization. Compared with control group, preloading group were younger, more likely to be male and present with Killip I classification. The proportion of hypertension and diabetes were higher in preloading group. After PS matching, all the variables used to generate PS score were well balanced. In the PS-matched cohort, 30-day mortality risk was 26.3% (292/1112) in the control group and 11.9% (132/1112) in the preloading group (p&lt;0.0001). Conclusions The current study found preloading statins treatment prior to reperfusion therapy reduced in-hospital mortality risk in a large-scale contemporary cohort of patients with STEMI.

Abstract Background Cardiac troponin (cTn) is the preferred biomarker for the diagnosis of acute myocardial infarction (AMI). Octogenarians who presented cTn positive AMI are not usually recruited in clinical trials. Therefore, their clinical characteristics and prognosis are rarely investigated. Objective To study the characteristics and prognosis in octogenarians who presented cTn positive AMI. Methods and results The Japanese registry of acute Myocardial INfarction diagnosed by Universal dEfiniTion (J-MINUET) is a prospective and multicenter registry. A total of 3,283 consecutive AMI patients who were diagnosed by cTn-based criteria were included. The patients were divided into non-octogenarians (n=2,593) and octogenarians (n=690). Compared with non- octogenarians, octogenarians showed significantly lower incidence of diabetes mellitus (37.6% and 31.9%, p=0.006) and dyslipidemia (53.6% and 45.6%, p<0.001), and significantly higher incidence of hypertension (64.1% and 75.3%, p<0.001) and chronic kidney disease (38.7% and 68.7%, p<0.001). Octogenarians showed significantly longer onset to door time (p<0.001) and longer door to device time (p<0.001). Though, compared with non-octogenarians, octogenarians showed lower peak CK (2,506 and 1,926, p<0.001), LVEF was significantly lower in octogenarians (54.6% and 52.6%, p=0.005). The presentation of AMI was different between the two group. The incidence of ST-segment elevation MI (STEMI) was 70.7% in non-octogenarians and 62.0% in octogenarians. Non-STEMI with CK elevation and without CK elevation were 16.2% and 13.1% in non- octogenarians, and 20.9% and 17.1% in octogenarians. In-hospital mortality was higher in octogenarians (4.7% and 13.2%, P<0.001). Especially, octogenarians with STEMI and non-STEMI with CK elevation showed the highest in-hospital mortality. And octogenarians without CK elevation showed similar in hospital mortality with non-octogenarians with STEMI (Figure). Conclusions J-MINUET showed the poor prognosis of octogenarians who were diagnosed as AMI based on cTn. Acknowledgement/Funding None

Introduction: Timely fibrinolytic therapy is recommended to reduce short-term mortality for patients with ST-elevation myocardial infarction (STEMI). However, the absolute treatment benefit is related to baseline mortality risk, and may be offset by the risks of major bleeding for low-risk patients. We constructed a baseline risk-assessment tool in eligible but untreated patients, to estimate the absolute benefits from fibrinolytic treatment. Methods: The China PEACE study includes a nationally representative sample of patients admitted with acute myocardial infarction (AMI) in 162 Chinese hospitals. Comprehensive clinical information was centrally abstracted from medical records using standardized data definitions. We identified 3741 patients with STEMI who were fibrinolytic-eligible, but did not receive reperfusion therapy, and separated the cohort randomly into derivation and validation cohorts. We employed classification and regression tree methods to produce a simple algorithm to estimate the risk of in-hospital mortality. Results: The overall in-hospital mortality rate was 14.7%. In both derivation and validation cohorts, the combination of systolic blood pressure (≥ 100 mm Hg), age (< 60 years old), and male gender identified one fifth of the patients with an average mortality risk less than 3.0%; half of this group with a non-anterior AMI had an average in-hospital mortality risk of 1.5%. The classification tree performed consistently across study years, and in hospitals with or without PCI capability. Conclusions: Nearly one in five fibrinolytic-eligible patients with STEMI have an low estimated risk of death, with an absolute benefit of fibrinolytic therapy could be insufficient to justify the risks of major bleeding. The tool with three simple factors, easily available at hospital presentation, can identify these individuals and support decision-making about the use of fibrinolytic therapy.

BackgroundWith the growing burden of non-ST-elevation myocardial infarction (NSTEMI), developing countries face great challenges in providing equitable treatment nationwide. However, little is known about hospital-level disparities in the quality of NSTEMI care in China. We aimed to investigate the variations in NSTEMI care and patient outcomes across the three hospital levels (province-, prefecture- and county-level, with decreasing scale) in China.MethodsData were derived from the China Acute Myocardial Infarction Registry on patients with NSTEMI consecutively registered between January 2013 and November 2016 from 31 provinces and municipalities throughout mainland China. Patients were categorized according to the hospital level they were admitted to. Multilevel generalized mixed models were fitted to examine the relationship between the hospital level and in-hospital mortality risk.ResultsIn total, 8,054 patients with NSTEMI were included (province-level: 1,698 patients; prefecture-level: 5,240 patients; county-level: 1,116 patients). Patients in the prefecture- and county-level hospitals were older, more likely to be female, and presented worse cardiac function than those in the province-level hospitals (P &lt;0.05). Compared with the province-level hospitals, the rate of invasive strategies was significantly lower in the prefecture- and county-level hospitals (65.3, 43.3, and 15.4%, respectively, P &lt;0.001). Invasive strategies were performed within the guideline-recommended timeframe in 25.4, 9.7, and 1.7% of very-high-risk patients, and 16.4, 7.4, and 2.4% of high-risk patients in province-, prefecture- and county-level hospitals, respectively (both P &lt;0.001). The use of dual antiplatelet therapy in the county-level hospitals (87.2%) remained inadequate compared to the province- (94.5%, P &lt;0.001) and prefecture-level hospitals (94.5%, P &lt;0.001). There was an incremental trend of in-hospital mortality from province- to prefecture- to county-level hospitals (3.0, 4.4, and 6.9%, respectively, P-trend &lt;0.001). After stepwise adjustment for patient characteristics, presentation, hospital facilities and in-hospital treatments, the hospital-level gap in mortality risk gradually narrowed and lost statistical significance in the fully adjusted model [Odds ratio: province-level vs. prefecture-level: 1.23 (0.73–2.05), P = 0.441; province-level vs. county-level: 1.61 (0.80–3.26), P = 0.182; P-trend = 0.246].ConclusionsThere were significant variations in NSTEMI presentation and treatment patterns across the three hospital levels in China, which may largely explain the hospital-level disparity in in-hospital mortality. Quality improvement initiatives are warranted, especially among lower-level hospitals.

ObjectivesCardiogenic shock (CS) complicating ST-elevation myocardial infarction (STEMI) carries an extremely high mortality. The clinical pattern of this life threatening complication has never been described in Malaysian setting. This study is to investigate the incidence, clinical characteristics and outcome of STEMI patients with CS in our population.DesignA retrospective analysis of STEMI patients from 18 hospitals across Malaysia contributing to the Malaysian National Cardiovascular Database-acute coronary syndrome) registry (NCVD-ACS) year 2006–2013.Participants16 517 patients diagnosed of STEMI from 18 hospitals in Malaysia from the year 2006 to 2013.Primary outcome measuresIn-hospital and 30 day post-discharge mortality.ResultsCS complicates 10.6% of all STEMIs in this study. They had unfavourable premorbid conditions and poor outcomes. The in-hospital mortality rate was 34.1% which translates into a 7.14 times mortality risk increment compared with STEMI without CS. Intravenous thrombolysis remained as the main urgent reperfusion modality. Percutaneous coronary interventions (PCI) in CS conferred a 40% risk reduction over non-invasive therapy but were only done in 33.6% of cases. Age over 65, diabetes mellitus, hypertension, chronic lung and kidney disease conferred higher risk of mortality.ConclusionMortality rates of CS complicating STEMI in Malaysia are high. In-hospital PCI confers a 40% mortality risk reduction but the rate of PCI among our patients with CS complicating STEMI is still low. Efforts are being made to increase access to invasive therapy for these patients.
