Background: Re-hospitalization rates are emerging as quality of care measures with reimbursement implications for inpatient care. Objective: To examine the rates of inpatient re-hospitalization and economic burden of acute coronary syndrome (ACS) patient admissions in real-world clinical practice. Methods: Patients (age >18 years) with an inpatient hospitalization for ACS [ICD-9-CM codes for acute myocardial infarction or unstable angina (UA)] between 1/1/2007-4/30/2009 were identified using claims from 450 hospitals representing 4.8 million inpatient visits. All-cause and ACS-related re-hospitalizations within 30 days and 12 months after index event were evaluated. In addition, the mean inpatient admission charges resulting from inpatient re-admissions at 30 days were also estimated. Results: Of 17,904 ACS patients [52% male; mean age 70.6 (median-73.0) years)], 13.3% had diagnostic coding for ST elevation myocardial infarction (STEMI), 47.9% had coding for non-ST elevation myocardial infarction (NSTEMI), 32.2% had UA, and 6.5% had not otherwise specified (NOS) ACS. The 30-day all-cause inpatient re-hospitalization rate was 14.7% (STEMI: 12.7%, NSTEMI: 17.1%, UA: 12.5%, NOS: 10.8%) and 5.5% for an ACS-related re-hospitalization (STEMI: 7.6%, NSTEMI: 7.0%, UA: 2.8%, NOS: 3.9%). The 12-month all cause re-hospitalization rate was 37.7% (STEMI: 31.3%, NSTEMI: 39.9%, UA: 39.7%, NOS: 25.4%) and 12.5% for an ACS-related re-hospitalization (STEMI: 12.7%, NSTEMI: 14.3%, UA: 10.9%, NOS: 7.0%). For patients with ages > 65 years (N = 12,627), the 30-day all-cause and ACS-related re-hospitalization rates were 15.1% and 5.8%, respectively. The mean per patient additional charges resulting from 30-day all-cause and ACS-related re-hospitalizations in the study cohort with an index hospitalization (N=17,904) were estimated to be $13,160 and $7,216, respectively. Conclusion: High rates of re-hospitalization for ACS patients within 30 days and 12-months post-index hospitalization were observed using real-world clinical practice data. More effective therapies may provide an opportunity to improve important clinical and economic outcomes in ACS patients.

Aim. To present the treatment of Acute coronary syndrome (ACS) in clinical practice in the Republic of Karelia and the results of Cardiovascular centers working. Material and methods. The prospective study included 9949 patients successively hospitalized from 01.01.2020 to 01.01.2020 in the Regional cardiovascular center (Petrozavodsk, Russia), 6335 were included in Federal register. Risk factors, clinical features, reperfusion strategy as well as the rate of clinical complications, drug therapy and outcomes were assessed. Results. 9949 patients were treated in Regional cardiovascular center from 01.01.2010 to 01.01.2020 due to acute coronary syndrome, and 6335 were included to the Federal registry. 40.2% of patients had ST-elevation Myocardial Infarction and 59.8% ACS without ST elevation. The first group was younger (the average age was 69) than the second (the average age was 74). The drug therapy of ACS in the hospital was following: 98.7% of patients took aspirin; b-blockers 92.3%, statins 97.4%. The outcomes of ACS during the hospital discharge were following: Q-wave myocardial infarction (MI) was diagnosed in 34.2% cases, non-Q-wave MI in 23.4%, unstable angina 20.5%, repeated MI 18.7% and 2.5% MI unspecified localization. The analysis of the clinical features of ACS shows that significant number of patients (24.8%) had severe complications. So, ventricle arrhythmias were diagnosed in 17.3% of cases, acute left ventricle insufficiency in 7.6%, cardiogenic shock in 3.0%, cardiac arrest in 1.9%, myocardial rupture in 0.4%. The hospital mortality rate reached 6.38%. Conclusion. The article presents data about treatment of patients with acute coronary syndrome in real clinical practice in the Republic of Karelia based on 10-years register. Difficulties of management and reperfusion interventions, the volume of drug therapy, the frequency of complications, as well as outcomes and hospital mortality are discussed. The presented data show the results of modernization of the medical care program for patients with acute coronary syndrome in practical healthcare in the region.

Introduction: N-Terminal pro Brain Natriuretic Peptide (NT-pro BNP) is an important biomarker in the management of patients with heart failure. Several studies reported its importance as a predictor of morbidity and mortality in Acute Coronary Syndrome (ACS) patients. Aim: To compare serum NT-proBNP levels in Non ST Elevation Acute Coronary Syndrome (NSTE-ACS) patients and controls and to assess the relation between Nt-proBNP and the severity of Coronary Artery Disease (CAD) in patients with NSTE-ACS including unstable Angina (UA) and Non ST Elevation Myocardial Infarction (NSTEMI). Materials and Methods: Sixty NSTE-ACS patients and 20 matched control without significant obstructive CAD were included in the study. Cardiac enzymes, blood urea, serum creatinine, serum NT-proBNP were measured in all patients immediately before coronary angiography. Gensini score and Syntax score were calculated for all study patients. The NSTE-ACS patients were followed-up for six months for Major Adverse Cardiovascular Events (MACE) including mortality, myocardial infarction, heart failure, stroke, revascularisation by primary percutaneous coronary intervention or Coronary Artery Bypass Grafting (CABG). Results: The mean serum NT-proBNP in NSTE-ACS (UA and NSTEMI) patients was significantly higher (662.7±635.2) pg/mL than that in the control (102.3±96.4) pg/mL, p<0.001. The effective cut-off value for the diagnosis of CAD was 139 pg/mL, Area Under Curve (AUC)=0.950, 95% CI: 0.890-1.00). The serum NT-proBNP was correlated with the severity and complexity of CAD as measured by Gensini score (r=0.496, p<0.001) and Syntax score (r=0.443, p<0.001). The mean value of NT-proBNP in patients with six months MACE was insignificantly higher than in patients without six months MACE with Interquartile Range (IQR) of 418.5 (139-2037) vs. 366 (175-3237) pg/mL, p=0.970. Conclusion: NT-proBNP was correlated with the severity and complexity of CAD in NSTE-ACS with preserved left ventricular systolic function, but it has no impact on six months MACE.

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.

BackgroundCardiovascular comorbidity is common among patients with chronic obstructive pulmonary disease (COPD) and there is concern that long-acting bronchodilators (long-acting muscarinic antagonists (LAMAs) and long-acting beta2 agonists (LABAs)) may further increase the risk of acute coronary events. Information about the impact of treatment intensification on acute coronary syndrome (ACS) risk in real-world settings is limited. We undertook a nationwide nested case–control study to estimate the risk of ACS in users of both a LAMA and a LABA relative to users of a LAMA.MethodsWe used routinely collected national health and pharmaceutical dispensing data to establish a cohort of patients aged >45 years who initiated long-acting bronchodilator therapy for COPD between 1 February 2006 and 30 December 2013. Fatal and non-fatal ACS events during follow-up were identified using hospital discharge and mortality records. For each case we used risk set sampling to randomly select up to 10 controls, matched by date of birth, sex, date of cohort entry (first LAMA and/or LABA dispensing), and COPD severity.ResultsFrom the cohort (n=83 417), we identified 5399 ACS cases during 281 292 person-years of follow-up. Compared with current use of LAMA therapy, current use of LAMA and LABA dual therapy was associated with a higher risk of ACS (OR 1.28 (95% CI 1.13 to 1.44)). The OR in an analysis restricted to fatal cases was 1.46 (95% CI 1.12 to 1.91).ConclusionIn real-world clinical practice, use of two versus one long-acting bronchodilator by people with COPD is associated with a higher risk of ACS.

BACKGROUND Cardiovascular diseases are one of the leading causes of morbidity and mortality worldwide. High Ca levels and low Mg levels are associated with increased cardiovascular risk in the general population.1 The balance between Ca and Mg seems to play an important role in homeostasis since Mg is considered as physiologic antagonist of Ca.2 Hence Ca/Mg ratio was considered to study its association with acute coronary syndrome (ACS). METHODS This is a case control study conducted in Karnataka Institute of Medical Sciences, Hubli over a period of 2 years, February 2019 to December 2020. 200 cases and 150 controls were included in the study. The biochemical measurements including complete blood count (CBC), cardiac biomarkers, liver function tests, renal function tests (RFT), serum electrolytes and lipid profile were measured using standard laboratory methods. Student ‘t’ test was used to compare the data. Optimum cut-offs for diagnosis of acute myocardial infarction was calculated using receiver operating characteristics (ROC) analysis. The association among markers was established by calculating Pearson’s correlation. RESULTS Serum Ca/Mg ratio was significantly higher (p value < 0.001) in ACS when compared to control groups. It was also found that Ca/Mg ratio was significantly lower (p value < 0.001) in non-ST elevation myocardial infarction (NSTEMI) when compared to STEMI group. Serum Mg was significantly lower (p value < 0.001) in ACS group when compared to control group. Significant correlation (p value < 0.05) was found between serum Ca/Mg ratio and cardiac markers (CKMB, Troponin-I). ROC analysis of Ca/Mg (4.19) ratios showed optimum cut-offs in diagnosis of AMI. CONCLUSIONS Serum Ca/Mg could be useful adjuvant marker in diagnosis of AMI. The ratio is higher in ST-segment elevation myocardial infarction when compared to non-STsegment myocardial infarction, which could be due to greater decrease in Mg levels when compared Ca in ACS.

The coronary care unit by Santa Izabel Hospital (Salvador, Bahia, Brazil) made a comparison of admitted patients with coronary disease cases admitted between two equivalent periods ranging from April through July in 2019 and 2020. There was a striking reduction in 2020 of cases of ST-elevation myocardial infarction (39%); non-ST elevation myocardial infarction (19%); and unstable angina pectoris (21%). This occurred in parallel with what happened in many parts of the world and hampered offering the best treatment strategy to these patients with an acute coronary syndrome such as invasive stratification and myocardial revascularization.

Background: Early identification and diagnosis are critical in the management of patients with acute coronary syndrome (ACS) since time-dependent therapies reduce patient mortality and morbidity. Objective: The aims of this study were to describe differences in presenting symptoms by individual ACS diagnoses and determine the prognostic value of both signs (electrocardiographic evidence of ischemia) and symptoms for an ACS diagnosis. Method: Patients > 21 years old, with any ECG ischemic changes (ST-elevation, ST-depression, T-wave inversion), elevated serum troponin, and ACS symptoms presenting to one of five emergency departments (ED) were eligible for the study. Patients completed the ACS Symptom Checklist, a validated 13-item instrument that measures cardiac symptoms (typical and atypical). Pearson Chi-square tests were used for bivariate analyses and logistic regression was used for multivariate modeling. Results: A total of 1,031 patients (mean age 60 + 14, 62% male, 70% White) were enrolled; 450 (43.7%) were diagnosed with ACS. One hundred eleven (11%) had ST-elevation myocardial infarction (STEMI), 236 (23%) had non-ST elevation myocardial infarction (NSTEMI), 103 (10%) had unstable angina (UA), and 581 (56%) were ruled-out for ACS. Patients with STEMI were more likely to report chest pain, diaphoresis, and higher symptom distress (p<0.05) at presentation than those without. Patients with NSTEMI were more likely to report arm pain and patients with UA were more likely to report lightheadedness (p<0.05). The presence of any chest symptoms (OR 2.24; 95% CI 1.27-3.97), higher symptom distress (OR 1.07; 95% CI 1.0-1.15), and a lower number of symptoms (OR 0.92; 95% CI 0.86-0.98) were independent predictors of an ACS diagnosis (p<0.05). The strongest predictor of an ACS diagnosis was the presence of ECG ischemic changes (OR 4.51, 95% CI 3.20-6.36) adjusting for symptoms, age, gender, heart rate, arrhythmia, and troponin levels (p<0.001). Conclusion: ECG signs of ischemia combined with specific symptom characteristics may enhance timely triage and detection of ACS in the ED. Predictive models that incorporate presenting signs and symptoms should be explored for this vulnerable population.

Purpose: Patients who present with concurrent heart failure (HF) and acute coronary syndrome (ACS) have an increased risk of mortality, but changes in clinical practice have improved clinical outcomes. We sought to examine recent trends in concurrent HF and ACS hospitalizations in the United States (US) through review of published literature. Methods: We searched the Medline and PubMed databases for studies published after January 1, 2000 reporting the hospitalizations for HF with concurrent acute coronary syndromes. We included studies performed in the US or with at least 25% US participants, that reported the proportion with concurrent HF and ACS, and used a clinical definition of HF (e.g. Killip Class II or III, NYHA Class, or Framingham Criteria). Studies were reviewed by and data was extracted using a standardized form. We extracted study and patient characteristics, definition of HF, and rates of concurrent HF and ACS hospitalizations. We categorized included studies by ACS type: (1) non-specific myocardial infarction (MI) or ACS, (2) non-ST elevation (NSTE) MI or NSTE-ACS, or (3) ST elevation (STE) MI. We descriptively examined recent trends in hospitalizations for concurrent HF and ACS over time; rates reported for multiple time periods or ACS types were considered separately. Results: We identified 23 observational studies, systematic reviews, and randomized clinical trials. Of these, we excluded 13 due to non-US populations, use of non-clinical definitions of HF (i.e., diagnosis codes), or not reporting rates of concurrent HF and ACS. Of the 10 included studies, 7 reported concurrent HF with non-specific MI or ACS from 1975 through 2005 across multiple registries and literature reviews. Rates ranged from 12.5% to 48.0% with no clear time-related trends. We identified 3 studies reporting concurrent HF with NSTEMI or NSTE-ACS from pooled analysis or the Global Registry of Acute Coronary Events (GRACE) registry from 1994 to 2008. Reported rates ranged from 8.2%-15.7% for studies starting in the 1990s with one study reporting and 6.1% in 2005. We identified 4 studies reporting concurrent HF with STEMI, including a pooled analysis, the GRACE registry, and a clinical trial. Rates of concurrent HF with STEMI appeared to decrease over time from 32.5% in 1990 to 1998, 15.6%-19.5% from 1999 to 2001, and 2.6%-11.0% in 2005. Conclusion: Our literature review found that there may be a decrease in concurrent HF and STEMI hospitalizations in recent decades, but no apparent trends with other types of ACS. This may be related to emphasis on early revascularization strategies, improved primary prevention, and/or earlier time to presentation due to increasing public awareness.. However, there was a dearth of data reporting concurrent HF and ACS hospitalization within the last decade. Further research is needed to understand the impact of multiple changes in clinical practice on secular trends.
