Objective: We aimed to evaluate Model for End-stage Liver Disease excluding international normalized ratio (MELD-XI) score for prediction of 30-day in-hospital mortality in a cohort of patients with ST elevation myocardial infarction. Methods: The medical records of a total of 256 patients admitted with ST elevation myocardial infarction to the emergency department between January 2015 and January 2019 were retrospectively reviewed. A total of 111 patients were found eligible for the study. MELD-XI score was analyzed and compared on the basis of survival status. Results: A total of 111 patients with a mean age of 62.5 ± 2.55 years were included in the study. In total, 81% (n = 90) of the patients were male and 19% (n = 21) were female. The mean MELD-XI score of the patients was 10.1 ± 1.1. A total of 12 patients (12.9%) died within 30 days after hospitalization. The median MELD-XI score of the patients who died in the hospital was significantly higher than the patients survived (11.0 (10.5–11.6) vs 9.5 (9.4–13.8); p < 0.01). However, Gensini score was not significantly different between the surviving and deceased patients (p > 0.05). MELD-XI score was significantly correlated to left ventricular ejection fraction (r = −232, p < 0.01), and both parameters and age were significant independent predictors of in-hospital mortality (odds ratio: 1.73, 95% confidence interval: 1.25–2.39, p < 0.05; odds ratio: 0.89, 95% confidence interval: 0.81–0.99, p < 0.05; and odds ratio: 1.07, 95% confidence interval: 0.99–1.15, p < 0.05, respectively). A MELD-XI cut-off point of 10 had a sensitivity of 100% and a specificity of 78.8% for in-hospital mortality (area under receiver operating characteristics curve: 0.92, 95% confidence interval: 0.87–0.97, p < 0.05). A survival analysis based on a MELD-XI threshold of 10 revealed that the patients in the high-MELD-XI group had a significantly worse in-hospital survival (log rank test p < 0.001). Conclusion: MELD-XI score is a useful tool for in-hospital mortality prediction in patients referring to emergency medicine with acute ST elevation myocardial infarction.

Background: Shock index is a bedside reflection of integrated response of the cardiovascular and nervous systems. We aimed to evaluate the utility of shock index (heart rate/systolic blood pressure) in patients presenting with acute coronary syndrome (ACS). Methods: We analyzed pooled data from seven Arabian Gulf registries; these ACS registries were carried out in seven countries (Qatar, Bahrain, Kuwait, UAE, Saudi Arabia, Oman and Yemen) between 2005 and 2017. A standard uniform coding strategy was used to recode each database using each registry protocol and clinical research form. Patients were categorized into two groups based on their initial shock index (low vs. high shock index). Optimal shock index cutoff was determined according to the receiver operating characteristic curve (ROC). Primary outcome was hospital mortality. Results: A total of 24,636 ACS patients met the inclusion criteria with a mean age 57±13 years. Based on ROC analysis, the optimal shock index was 0.80 (83.5% had shock index <0.80 and 16.5% had shock index ≥0.80). In patients with high shock index, 55% had ST-elevation myocardial infarction and 45% had non-ST-elevation myocardial infarction. Patients with high shock index were more likely to have diabetes mellitus, late presentation, door to electrocardiogram >10 min, symptom to Emergency Department > 3 h, anterior myocardial infarction, impaired left ventricular function, no reperfusion post-therapy, recurrent ischemia/myocardial infarction, tachyarrhythmia and stroke. However, high shock index was associated significantly with less chest pain, less thrombolytic therapy and less primary percutaneous coronary intervention. Shock index correlated significantly with pulse pressure ( r= −0.52), mean arterial pressure ( r= −0.48), Global Registry of Acute Coronary Events score ( r =0.41) and Thrombolysis In Myocardial Infarction simple risk index ( r= −0.59). Shock index ≥0.80 predicted mortality in ACS with 49% sensitivity, 85% specificity, 97.6% negative predictive value and 0.6 negative likelihood ratio. Multivariate regression analysis showed that shock index was an independent predictor for in-hospital mortality (adjusted odds ratio (aOR) 3.40, p<0.001), heart failure (aOR 1.67, p<0.001) and cardiogenic shock (aOR 3.70, p<0.001). Conclusions: Although shock index is the least accurate of the ones tested, its simplicity may argue in favor of its use for early risk stratification in patients with ACS. The utility of shock index is equally good for ST-elevation myocardial infarction and non-ST-elevation acute coronary syndrome. High shock index identifies patients at increased risk of in-hospital mortality and urges physicians in the Emergency Department to use aggressive management.

Abstract Background Cardiogenic shock (CS) in patients (pts) with acute ST elevation myocardial infarction (STEMI) is the strongest predictor of hospital mortality. Radial in contrast to femoral access in STEMI pts might be associated with a lower mortality. However, little is known on radial access in CS pts. Methods We retrospectively analysed all STEMI pts between 2009 and 2015 who sufferend from CS and who were included into the ALKK PCI registry. Pts treated via a radial access were compared to those treated via a femoral access. Results Between 2009 and 2015 23796 STEMI pts were included in the registry. 1763 (7.4%) of pts were in CS. The proportion of radial access was 6.6%: in 2009 4.0% and in 2015 19.6%, p for trend &lt;0.0001 with a strong variation between the participating centres (0% to 37%). Conclusions Radial access was only used in 6.6% of STEMI pts presenting in CS. However, a significant increase in the use of radial access was observed over time (2009: 4%, 2015 19.6%, p&lt;0.001), with a great variance in its use between the participating hospitals. Despite similar pt characteristics the difference in hospital mortality according to access site has to be interpretated with caution. Funding Acknowledgement Type of funding source: None

Vascular calcification contributes to the pathogenesis of coronary artery disease while matrix Gla protein (MGP) was recently identified as a potent inhibitor of vascular calcification. MGP fractions, such as dephosphorylated-uncarboxylated MGP (dp-ucMGP), lack post-translational modifications and are less efficient in vascular calcification inhibition. We sought to compare dp-ucMGP levels between patients with acute coronary syndrome (ACS), stratified by ST-elevation myocardial infarction (STEMI) and non-ST-elevation myocardial infarction (NSTEMI) status. Physical examination and clinical data, along with plasma dp-ucMGP levels, were obtained from 90 consecutive ACS patients. We observed that levels of dp-ucMGP were significantly higher in patients with NSTEMI compared to STEMI patients (1063.4 ± 518.6 vs. 742.7 ± 166.6 pmol/L, p < 0.001). NSTEMI status and positive family history of cardiovascular diseases were only independent predictors of the highest tertile of dp-ucMGP levels. Among those with NSTEMI, patients at a high risk of in-hospital mortality (adjudicated by GRACE score) had significantly higher levels of dp-ucMGP compared to non-high-risk patients (1417.8 ± 956.8 vs. 984.6 ± 335.0 pmol/L, p = 0.030). Altogether, our findings suggest that higher dp-ucMGP levels likely reflect higher calcification burden in ACS patients and might aid in the identification of NSTEMI patients at increased risk of in-hospital mortality. Furthermore, observed dp-ucMGP levels might reflect differences in atherosclerotic plaque pathobiology between patients with STEMI and NSTEMI.

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.
