Previous studies reported regional variations in in-hospital acute coronary syndrome (ACS) mortality, but the reasons for that were not clearly defined. We explored whether differences in patient characteristics could explain regional variation. The Improving Care for Cardiovascular Disease in China (CCC)-ACS project is an ongoing national registry and quality improvement project, involving 150 tertiary hospitals from 30 provinces across China. We applied a prediction model that included patient-specific variables to calculate the expected in-hospital mortality. For each province, we reported the observed, expected in-hospital mortality and the risk-adjusted ratio which is based on the observed divided by the expected mortality. From 2014 to 2018, 79 585 ACS patients were enrolled. The average in-hospital mortality was 1.8%. There was a wide variation in the in-hospital mortality among different provinces (0.2-3.9%). Patient characteristics explained part of this variation because of differences in the expected in-hospital mortality (0.7-2.8%). There was a substantial variation in the risk-adjusted ratio among provinces (0.2-3.5), which suggests that the variations in the mortality cannot be completely explained by the differences in patient characteristics. In conclusion, we observed a wide regional variation in mortality for ACS, part of which could be explained by the difference in patient characteristics.

Background: Regional variation in the utilization of health services is a well-documented phenomenon in health care with numerous studies reporting substantial and unexplained variations in coronary revascularization. In the Canadian province of British Columbia (BC), five cardiac centers provide coronary revascularization services. In 2011 Cardiac Services BC (CSBC) undertook a study that identified substantial regional variation in coronary revascularization that could not be explained by patient characteristics or risk factors. Following this initial project, CSBC launched an initiative to help better understand the regional variations and possibly devise and implement strategies to reduce them. To get a better understanding of the different processes of care/utilization, one of the approaches used is the application of Lean methodology to the care of acute coronary syndrome (ACS) patients. Methods: Lean methodology is being applied to the patient journey of ACS patients. At each revascularization center Value Steam Maps process maps (VSM) are being prepared through a series of meetings with support, frontline, administrative and clinical staff (see attached example). For each VSM the goal is to identify key decision points in the process of care for ACS patients and to drill down on (Root Cause Analysis) on the decision making environment and criteria used to determine the utilization of coronary revascularization services. Once VSM have been completed they will be compared across sites for similarities and differences. The differences in decision making will then be assessed to determine their effect on variation in utilization across the centers. Discussion: BC is attempting to reduce unexplained variation in coronary revascularization using the Lean methodology to take a systematic approach to the analysis of the process of ACS care across the province. The next step will be to determine to what extent it is possible to standardize decision making at the key decision points across the HAs. Standardization will be achieved through a mix of best practices, evidence and application of guidelines. While the undertaking is still in the early stages it is expected that it will lead to, at the very least, ACS patients receiving the same care regardless of where they receive their care in BC.

Abstract Background Atrial fibrillation (AF) is the most common cardiac arrhythmia in patients with chronic kidney disease (CKD) and acute coronary syndrome (ACS). This study aimed to explore the frequency and impact of AF on clinical outcomes in CKD patients with ACS. Methods CKD inpatients with ACS between November 2014 and December 2018 were included based on the improving care for cardiovascular disease in China-ACS (CCC-ACS) project. Included patients were divided into an AF group and a non-AF group according to the discharge diagnosis. Multivariable logistic regression was used to adjust for potential confounders. Results A total of 16,533 CKD patients with ACS were included. A total of 1418 (8.6%) patients had clinically recognized AF during hospitalization, 654 of whom had an eGFR of 45 to < 60 ml/min/1.73 m2, and 764 had an estimated glomerular filtration rate (eGFR) < 45 ml/min/1.73 m2. Compared with the non-AF group, the AF group had a higher risk of in-hospital mortality [OR 1.250; 95% CI (1.001–1.560), P = 0.049] and major adverse cardiovascular events (MACEs) [OR 1.361; 95% CI (1.197–1.547), P < 0.001]. We also found that compared with patients with eGFR 45 to < 60 ml/min/1.73 m2, patients with eGFR < 45 ml/min/1.73 m2 had a 1.512-fold increased risk of mortality and a 1.435-fold increased risk of MACEs. Conclusions AF was a risk factor affecting the short-term prognosis of ACS patients in the CKD population. Furthermore, the lower the eGFR, the higher the risk of in-hospital mortality and MACEs in CKD patients with ACS. Trial registry: Clinicaltrial.gov, NCT02306616.

Introduction Data regarding patients with acute coronary syndrome (ACS) did not exist in Serbia until 2002. By establishing the National Registry for Acute Coronary Syndrome (NRACS), the data collection based on the filled-in "coronary questionnaire" for each patient hospitalized and diagnosed with acute infarction of the myocardium (AIM) and unstable angina pectoris (UAP) was initiated in Serbia. Objective The aim of the study was to analyze clinical characteristics, complications, applied reperfusion-thrombolytic treatment and standard therapy, and mortality rate of patients treated in coronary or intensive care units during the 2002, 2003, 2004 and 2005. Method We chose a "coronary protocol" with minimal set of the patient?s data that was filled-in by the attending physician. The collection of the data was initiated in July 2002. Results During four months of 2002, 4202 patients were treated for ACS; in 2003 12739 patents, in 2004 12351 patients and 12598 patients in 2005. AIM with ST elevation (STAIM), as related to AIM without ST elevation (NSTAIM), was more often encountered in Serbian population in comparison to other European countries: in 2002, it was registered among 52.3% of patients, in 2003 among 52.7%, in 2004 among 51.8%, and in 2005 among 50.7% of patients. The patients suffering from the ACS in Serbia were of younger age, with a significant prevalence of females, as compared to the data from the European countries. Thrombolytic therapy in STAIM was applied in only 24.5% of patients in 2002, which then rose by each year, to reach 36.4% of patients in 2005. At the same time, as expected, hospital mortality rate decreased: from 14.8% in 2002 to 8.2% in 2005. STAIM patients untreated by thrombolytic therapy had a considerably higher mortality rate: in 2002 it was 20.3%, in 2003 15.3%, in 2004 14.3%, and in 2005 13.8%. Total mortality rate in patients with STAIM gradually decreased from 19% in 2002 to 11.7% in 2005. Conclusion From 2002-2005, the patients treated for ACS in Serbia were younger, with higher prevalence of females, and with a higher incidence of STAIM in relation to NSTAIM. The administration of reperfusion therapy in STAIM patients has been increasing significantly, from 24.5% in 2002 to 36.4% in 2005, and was followed by a decrease in hospital mortality rate of 14.8% in 2002 to 8.2% in 2005. Overall mortality of STAIM patients treated with or without thrombolytic therapy gradually decreased from19% in 2002 to 11.7% in 2005.

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 obesity paradox – indicating improved short term mortality in obese individuals has been widely explored in a number of cardiovascular conditions. However, its validity in an elderly population and the possible physiological impact of aging on this phenomenon in Acute Coronary syndrome (ACS) remain unclear. In this study, we aim to determine the relationship between obesity and in-hospital mortality, morbidity, and health care resource utilization in this cohort of patients. Methods A retrospective study was conducted using the AHRQ-HCUP National Inpatient Sample for the year 2014. Elderly adults (≥65 years) with a principal diagnosis of ACS and a secondary diagnosis of obesity were identified using ICD-9 diagnosis codes as described in the literature. The primary outcome of in-hospital mortality and secondary outcomes like length of hospital stay (LOS), and total hospitalization costs were analyzed. Propensity score (PS) using the next neighbor method without replacement with 1:1 matching was utilized to adjust for confounders. Independent risk factors for mortality were identified using a multivariate logistic regression model. Results In total, 1,137,108 hospital admissions with a primary diagnosis of ACS were identified, of which 7.46% were obese. In-hospital morality during the index admission was lower among obese patients with ACS compared to non-obese patients (4.62 vs 6.87%, p&lt;0.001) with significantly lower 30-day readmission rates as well (p&lt;0.001). However, in-hospital mortality rates during readmission were statistically equivalent between the obese and non-obese groups (5.6 vs 8.3%, p=0.72). LOS during the index admission was longer for obese patients (6.39 vs 5.36 days, p=0.65) but equivalent to non-obese patients during subsequent readmissions (p=0.12). The total cost of these admissions was significantly more in the obese cohort as well (p&lt;0.001). Conclusion In this study, obese elderly patients admitted with ACS were found to have significantly reduced in-hospital mortality and 30-day readmission rates when compared to non-obese patients - reinforcing the obesity paradox independent of patient age.

AbstractCOVID-19 pandemic has negatively impacted the management of patients with acute and chronic cardiovascular disease: acute coronary syndrome patients were often not timely reperfused, heart failure patients not adequately followed up and titrated, atrial arrhythmias not efficaciously treated and became chronic. New phenotypes of cardiovascular patients were more and more frequent during COVID-19 pandemic and are expected to be even more frequent in the next future in the new world shaped by the pandemic. We therefore aimed to briefly summarize the main changes in the phenotype of cardiovascular patients in the COVID-19 era, focusing on new clinical challenges and possible therapeutic options.
