Abstract
BACKGROUND Limited data exist regarding the prognostic implications of N-terminal pro-B-type natriuretic peptide (NT-proBNP) in patients with non-ST-elevation myocardial infarction (NSTEMI) who undergo percutaneous coronary intervention (PCI).Methods and Results: Of 13,104 patients in the nationwide Korea Acute Myocardial Infarction Registry-National Institutes of Health, 3,083 patients with NSTEMI who underwent PCI were included in the present study. The primary endpoint was major adverse cardiovascular events (MACE) at 3 years, a composite of all-cause death, recurrent myocardial infarction, unplanned repeat revascularization, and admission for heart failure. NT-proBNP was measured at the time of initial presentation for the management of NSTEMI, and patients were divided into a low (<700 pg/mL; n=1,813) and high (≥700 pg/mL; n=1,270) NT-proBNP group. The high NT-proBNP group had a significantly higher risk of MACE, driven primarily by a higher risk of cardiac death or admission for heart failure. These results were consistent after confounder adjustment by propensity score matching and inverse probability weighting analysis. CONCLUSIONS In patients with NSTEMI who underwent PCI, an initial elevated NT-proBNP concentration was associated with higher risk of MACE at 3 years, driven primarily by higher risks of cardiac death or admission for heart failure. These results suggest that the initial NT-proBNP concentration may have a clinically significant prognostic value in NSTEMI patients undergoing PCI.

Treatment of elderly patients with non-ST-elevation myocardial infarction: the nationwide POPular age registry. Neth Heart J 2024; 32:84-90. [PMID: 37768542 PMCID: PMC10834918 DOI: 10.1007/s12471-023-01812-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 08/02/2023] [Indexed: 09/29/2023] Open
Abstract
OBJECTIVE We describe the current treatment of elderly patients with non-ST-elevation myocardial infarction (NSTEMI) enrolled in a national registry. METHODS The POPular AGE registry is a prospective, multicentre study of patients ≥ 75 years of age presenting with NSTEMI, performed in the Netherlands. Management was at the discretion of the treating physician. Cardiovascular events consisted of cardiovascular death, myocardial infarction and ischaemic stroke. Bleeding was classified according to the Bleeding Academic Research Consortium (BARC) criteria. RESULTS A total of 646 patients were enrolled between August 2016 and May 2018. Median age was 81 (IQR 77-84) years and 58% were male. Overall, 75% underwent coronary angiography, 40% percutaneous coronary intervention, and 11% coronary artery bypass grafting, while 49.8% received pharmacological therapy only. At discharge, dual antiplatelet therapy (aspirin and P2Y12 inhibitor) was prescribed to 56.7%, and 27.4% received oral anticoagulation plus at least one antiplatelet agent. At 1‑year follow-up, cardiovascular death, myocardial infarction or stroke had occurred in 13.6% and major bleeding (BARC 3 and 5) in 3.9% of patients. The risk of both cardiovascular events and major bleeding was highest during the 1st month. However, cardiovascular risk was three times as high as bleeding risk in this elderly population, both after 1 month and after 1 year. CONCLUSIONS In this national registry of elderly patients with NSTEMI, the majority are treated according to current European Society of Cardiology guidelines. Both the cardiovascular and bleeding risk are highest during the 1st month after NSTEMI. However, the cardiovascular risk was three times as high as the bleeding risk.

The association between cardiovascular risk profile and ocular microvascular changes in patients with non-ST elevation myocardial infarction. Microvasc Res 2023; 150:104575. [PMID: 37429354 DOI: 10.1016/j.mvr.2023.104575] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Revised: 06/14/2023] [Accepted: 06/29/2023] [Indexed: 07/12/2023]
Abstract
PURPOSE We aimed to evaluate the association between ocular microvasculature (vascular density) on optical coherence tomography-angiography (OCT-A) and the cardiovascular risk profile of patients hospitalized for non-ST-elevation myocardial infarction (NSTEMI) patients. METHODS Patients admitted to the intensive care unit with the diagnosis of NSTEMI and undergoing coronary angiography were divided into 3 groups as low, intermediate, and high risk according to the SYNTAX score. OCT-A imaging was performed in all three groups. Right-left selective coronary angiography images of all patients were analyzed. The SYNTAX and TIMI risk scores of all patients were calculated. RESULTS This study included opthalmological examination of 114 NSTEMI patients. NSTEMI patients with high SYNTAX risk scores had significantly lower deep parafoveal vessel density (DPD) than patients with low-intermediate SYNTAX risk scores (p < 0.001). ROC curve analysis found that a DPD threshold below 51.65 % was moderately associated with high SYNTAX risk scores in patients with NSTEMI. In addition, NSTEMI patients with high TIMI risk scores had significantly lower DPD than patients with low-intermediate TIMI risk scores (p < 0.001). CONCLUSIONS OCT-A may be a non-invasive useful tool to assess the cardiovascular risk profile of NSTEMI patients with a high SYNTAX and TIMI score.

Prehospital stratification and prioritisation of non-ST-segment elevation acute coronary syndrome patients (NSTEACS): the MARIACHI scale. Intern Emerg Med 2023; 18:1317-1327. [PMID: 37131092 DOI: 10.1007/s11739-023-03274-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/18/2023] [Accepted: 04/11/2023] [Indexed: 05/04/2023]
Abstract
OBJECTIVE The objective of this study was to develop and validate a risk scale (MARIACHI) for patients classified as non-ST-segment elevation acute coronary syndrome (NSTEACS) in a prehospital setting with the ability to identify patients at an increased risk of mortality at an early stage. METHODS A retrospective observational study conducted in Catalonia over two periods: 2015-2017 (development and internal validation cohort) and Aug 2018-Jan 2019 (external validation cohort). We included patients classified as prehospital NSTEACS, assisted by an advanced life support unit and requiring hospital admission. The primary outcome was in-hospital mortality. Cohorts were compared using logistic regression and a predictive model was created using bootstrapping techniques. RESULTS The development and internal validation cohort included 519 patients. The model is composed of five variables associated with hospital mortality: age, systolic blood pressure, heart rate > 95 bpm, Killip-Kimball III-IV and ST depression ≥ 0.5 mm. The model showed good overall performance (Brier = 0.043) and consistency in discrimination (AUC 0.88, 95% CI 0.83-0.92) and calibration (slope = 0.91; 95% CI 0.89-0.93). We included 1316 patients for the external validation sample. There was no difference in discrimination (AUC 0.83, 95% CI 0.78-0.87; DeLong Test p = 0.071), but there was in calibration (p < 0.001), so it was recalibrated. The finally model obtained was stratified and scored into three groups according to the predicted risk of patient in-hospital mortality: low risk: < 1% (-8 to 0 points), moderate risk: 1-5% (+ 1 to + 5 points) and high risk: > 5% (6-12 points). CONCLUSION The MARIACHI scale showed correct discrimination and calibration to predict high-risk NSTEACS. Identification of high-risk patients may help with treatment and low referral decisions at the prehospital level.

Development and validation of a predictive model for adverse left ventricular remodeling in NSTEMI patients after primary percutaneous coronary intervention. BMC Cardiovasc Disord 2022; 22:386. [PMID: 36030211 PMCID: PMC9420298 DOI: 10.1186/s12872-022-02831-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Accepted: 08/22/2022] [Indexed: 11/21/2022] Open
Abstract
Introduction To develop and validate clinical evaluators that predict adverse left ventricular remodeling (ALVR) in non-ST-elevation myocardial infarction (NSTEMI) patients after primary percutaneous coronary intervention (PCI). Methods The retrospective study analyzed the clinical data of 507 NSTEMI patients who were treated with primary PCI from the Affiliated Hospital of Xuzhou Medical University and the Second Affiliated Hospital of Xuzhou Medical University, between January 1, 2019 and September 31, 2021. The training cohort consisted of patients admitted before June 2020 (n = 287), and the remaining patients (n = 220) were assigned to an external validation cohort. The endpoint event was the occurrence of ALVR, which was described as an increase ≥ 20% in left ventricular end-diastolic volume (LVEDV) at 3–4 months follow-up CMR compared with baseline measurements. The occurrence probability of ALVR stemmed from the final model, which embodied independent predictors recommended by logistic regression analysis. The area under the receiver operating characteristic curve (AUC), Calibration plot, Hosmer–Lemeshow method, and decision curve analysis (DCA) were applied to quantify the performance. Results Independent predictors for ALVR included age (odds ratio (OR): 1.040; 95% confidence interval (CI): 1.009–1.073), the level of neutrophil to lymphocyte ratio (OR: 4.492; 95% CI: 1.906–10.582), the cardiac microvascular obstruction (OR: 3.416; 95% CI: 1.170–9.970), peak global longitudinal strain (OR: 1.131; 95% CI: 1.026–1.246), infarct size (OR: 1.082; 95% CI: 1.042–1.125) and left ventricular ejection fraction (OR: 0.925; 95% CI: 0.872–0.980), which were screened by regression analysis then merged into the nomogram model. Both internal validation (AUC: 0.805) and external validation (AUC: 0.867) revealed that the prediction model was capable of good discrimination. Calibration plot and Hosmer–Lemeshow method showed high consistency between the probabilities predicted by the nomogram (P = 0.514) and the validation set (P = 0.762) and the probabilities of actual occurrence. DCA corroborated the clinical utility of the nomogram. Conclusions In this study, the proposed nomogram model enabled individualized prediction of ALVR in NSTEMI patients after reperfusion and conduced to guide clinical therapeutic schedules.

Evaluating the systemic immune-inflammation index for in-hospital and long-term mortality in elderly non-ST-elevation myocardial infarction patients. Aging Clin Exp Res 2022; 34:1687-1695. [PMID: 35275375 DOI: 10.1007/s40520-022-02103-1] [Citation(s) in RCA: 15] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2021] [Accepted: 02/22/2022] [Indexed: 01/03/2023]
Abstract
INTRODUCTION This investigation aimed to evaluate the predictive value of the systemic immune-inflammation index (SII) for in-hospital and long-term mortality in elderly patients with non-ST-elevation myocardial infarction (NSTEMI). METHODS This retrospective investigation included 314 consecutive elderly NSTEMI patients in a tertiary center. SII is computed as (neutrophils × platelets)/lymphocytes. Based on the increased SII values, we classified the research sample into three tertile groups as T1, T2, and T3. The in-hospital and long-term mortality were defined as the primary outcomes. RESULTS Patients in the T3 group had lower chances of survival in the in-hospital and long-term periods compared with those in the T2 and T1 groups. According to the multivariable Cox regression models, SII independently related with in-hospital (hazard ratio (HR): 1.001, 95% CI: 1.000-1.1003, p = 0.038) and long-term mortality (HR: 1.004, 95% CI: 1.002-1.006, p < 0.001). To predict long-term mortality, the optimal SII value was > 2174 with 80% sensitivity and 85.4% specificity. SII had a slightly lower but statistically non-inferior discriminative ability for long-term mortality compared with the Charlson comorbidity index (CCI) in the receiver operating characteristic curve comparison (AUC: 86.2 vs. AUC: 890, p > 0.05). Additionally, combining SII with traditional risk factors and the CCI revealed a significant improvement in C-statistics. CONCLUSION This investigation may be the first to demonstrate that SII is independently linked with in-hospital and long-term mortality in elderly NSTEMI patients.

Coronary-specific quantification of myocardial deformation by strain echocardiography may disclose the culprit vessel in patients with non-ST-segment elevation acute coronary syndrome. EUROPEAN HEART JOURNAL OPEN 2022; 2:oeac010.

Abstract
Aims To compare the diagnostic accuracy of speckle tracking echocardiography technique using territorial longitudinal strain (TLS) for the detection of culprit vessel vs. vessel-specific wall motion score index (WMSI) in non-ST-segment elevation–acute coronary syndrome (NSTE-ACS) patients scheduled for invasive coronary angiography (ICA). Methods and results One hundred and eighty-three patients (mean age: 66 ± 12 years, male: 71%) diagnosed with NSTE-ACS underwent echocardiography evaluation at hospital admission and ICA within 24 h. Culprit vessels were left anterior descending (LAD), left circumflex (CX), and right coronary arteries (RCAs) in 38.5%, 39.6%, and 21.4%, respectively. An increase of affected vessels [1-, 2-, and 3-vessel coronary artery disease (CAD)] was associated with increased WMSI and TLS values. There was a statistically significant difference of both WMSI-LAD, WMSI-CX, WMSI-RCA and TLS-LAD, TLS-CX, TLS-RCA of myocardial segments with underlying severe CAD compared to no CAD (P = 0.001 and P < 0.001, respectively). Moreover, a significant difference of TLS-LAD, TLS-CX, TLS-RCA, and WMSI-CX of myocardial segments with an underlying culprit vessel compared to non-culprit vessels (P < 0.001, P < 0.001, P = 0.022, and P < 0.001, respectively) was identified. WMSI-LAD and WMSI-RCA did not show statistical significant differences. A regression model revealed that the combination of WMSI + TLS was more accurate compared to WMSI alone in detecting the culprit vessel (LAD, P = 0.001; CX, P < 0.001; and RCA, P = 0.019). Conclusion Territorial longitudinal strain allows an accurate identification of the culprit vessel in NSTE-ACS patients. In addition to WMSI, TLS may be considered as part of routine echocardiography for better clinical assessment in this subset of patients.

Abstract
OBJECTIVES To determine the anti-inflammatory effect and safety of hydroxychloroquine after acute myocardial infarction. METHOD In this multicenter, double-blind, placebo-controlled OXI trial, 125 myocardial infarction patients were randomized at a median of 43 h after hospitalization to receive hydroxychloroquine 300 mg (n = 64) or placebo (n = 61) once daily for 6 months and, followed for an average of 32 months. Laboratory values were measured at baseline, 1, 6, and 12 months. RESULTS The levels of interleukin-6 (IL-6) were comparable at baseline between study groups (p = 0.18). At six months, the IL-6 levels were lower in the hydroxychloroquine group (p = 0.042, between groups), and in the on-treatment analysis, the difference at this time point was even more pronounced (p = 0.019, respectively). The high-sensitivity C-reactive protein levels did not differ significantly between study groups at any time points. Eleven patients in the hydroxychloroquine group and four in the placebo group had adverse events leading to interruption or withdrawal of study medication, none of which was serious (p = 0.10, between groups). CONCLUSIONS In patients with myocardial infarction, hydroxychloroquine reduced IL-6 levels significantly more than did placebo without causing any clinically significant adverse events. A larger randomized clinical trial is warranted to prove the potential ability of hydroxychloroquine to reduce cardiovascular endpoints after myocardial infarction.

Abstract
Myocarditis and myocardial infarction share a common clinical characteristics despite significant differences in etiology and pathogenesis. Current guidelines recommend using cardiac magnetic resonance imaging (MRI) or endocardial biopsy for a definite diagnosis; however, these guidelines are not fully implemented due to the high cost and low availability. We used a thrombin generation assay and simple blood test to characterize both diseases. We conducted a cross-sectional study from April to December 2018. Patients with initial clinical suspicions of non-ST elevation myocardial infarction (NSTEMI) or myocarditis were eligible. All patients were recruited prior to anticoagulant treatment. Patients in both groups underwent acceptable standard clinical evaluation. Twenty-eight patients were enrolled; 12 patients in the NSTEMI group and 16 in the myocarditis group. Patients in the NSTEMI group were significantly older than those in the myocarditis group (64.25 ± 9.67 vs. 37.94 ± 19.66 years, p < 0.01, respectively) with a higher prevalence of hyperlipidemia, diabetes mellitus, and ischemic heart disease (p < 0.01 for all). There was no difference between the groups regarding INR, PT, aPTT, and serum levels of creatinine, urea, CPK, troponin, and fibrinogen. Endogenous thrombin potential (ETP), which represents the total thrombin concentration in the plasma, was significantly higher in the myocarditis group than in the NSTEMI group (2091.88 ± 336.41 vs. 1860.75 ± 438.02 nM × min, p < 0.03). Myocarditis and myocardial infarction have a different pattern of thrombin generation Thrombogram. The myocarditis group had significantly higher plasma ETP than the NSTEMI group. This finding requires further evaluation to define a numerical threshold, thus avoiding invasive or expensive assessment of myocarditis.

Abstract
An important task in emergency cardiology is distinguishing patients with acute coronary occlusion (ACO), who will benefit from emergent reperfusion therapy, from those without ongoing myocyte loss who can be managed with medical therapy and for whom potentially harmful invasive interventions can be deferred. The electrocardiogram is critical in this process. Although the ST-segment elevation myocardial infarction (STEMI)/non-STEMI paradigm is well-established, with "STEMI" representing ACO, its evidence base is poor, and this can have dire consequences. The universally recommended STEMI criteria do not accurately diagnose ACO; in fact, they miss more than one-fourth of the patients with ACO, and also result in a substantial burden of unnecessary catheterization laboratory activations. We here discuss why we believe it is time to change the current STEMI/non-STEMI paradigm.

Abstract
INTRODUCTION Current assays based on the 0-hour/1-hour (0-/1-h) algorithm using high-sensitivity cardiac troponin (hs-cTn) are limited to only Abbott Architect hs-cTnI, Siemens Vista hs-cTnI, and Roche Elecsys hs-cTnT. OBJECTIVE This study aimed to evaluate this new hs-cTnI assay, LumipulsePresto hs Troponin I, for diagnosis of acute myocardial infarction (AMI) on admission and on 0-/1-h algorithm to stratify AMI patients precisely. METHODS This prospective cohort study included 442 patients with suspected non-ST-elevation myocardial infarction in three hospitals in Japan and Taiwan from June 2016 to January 2019. We enrolled patients presenting to the emergency department with symptoms suggestive of AMI and collected blood samples on admission and 1 hour later. Two independent cardiologists centrally adjudicated final diagnoses; all clinical information was reviewed twice: first, using serial hs-cTnT (Roche-Elecsys, primary analysis) and Lumipulse Presto Lumipulse Presto, second, using the Lumipulse Presto hs-cTnI measurements. At first, we compared diagnostic accuracy quantified using receiver operating characteristic (ROC) curves for AMI. Then, we evaluated major adverse cardiovascular events (cardiac death, AMI) in the rule-out group according to a 0-hour/1-hour algorithm at the 30-day follow-up. RESULTS Diagnostic accuracy at presentation by the ROC curve for AMI was very high and similar for the LumipulsePresto hs-cTnI and hs-cTnT,(area under the curve [AUC]: LumipulsePresto hs-cTnI, 0.89, 95% confidence interval [CI] 0.86-0.93; hs-cTnT, 0.89, 95% CI 0.85-0.93; p = 0.82). In early presenters, the LumipulsePresto hs-cTnI appeared to maintain the diagnostic performance of hs-cTn for patients with <3 h (AUC: LumipulsePresto hs-cTnI, 0.87, 95% CI 0.81-0.92; hs-cTnT, 0.86, 95% CI 0.80-0.92; p = 0.81). The algorithm using the LumipulsePresto hs-cTnI ruled out AMI in 200 patients with negative predictive value and sensitivity of 100% (95% CI 97.3%-100%) and 100% (95% CI 92.7%-100%), respectively, in the rule-out group. CONCLUSION Diagnostic accuracy and clinical utility of the novel LumipulsePresto hs-cTnI assay are high and comparable with the established hs-cTn assays.

Abstract
BACKGROUND There is a paucity of data on the outcomes of acute myocardial infarction in patients with rheumatoid arthritis in the contemporary era. METHODS We queried the National Inpatient Sample database (2002-2016) for hospitalizations with acute myocardial infarction. We described the trends and outcomes of acute myocardial infarction-rheumatoid arthritis compared with acute myocardial infarction-no rheumatoid arthritis. RESULTS The analysis included 9,359,546 hospitalizations with acute myocardial infarction, of whom 123,783 (1.3%) had rheumatoid arthritis. There was an increase in the number of hospitalizations with acute myocardial infarction-rheumatoid arthritis (Ptrend < .001). There was an observed downtrend in mortality rates for acute myocardial infarction-rheumatoid arthritis (5.8% in 2002 vs 5.2% in 2016, Ptrend = .01) corresponding to an increase in the utilization of percutaneous coronary intervention (Ptrend < .001). In the overall cohort of acute myocardial infarction, rheumatoid arthritis was independently associated with lower rate of in-hospital mortality (adjusted odds ratio 0.90; 95% confidence interval, 0.81-0.99, P = .03). Compared with ST-elevation myocardial infarction (STEMI)-no rheumatoid arthritis, STEMI-rheumatoid arthritis was associated with lower in-hospital mortality and cardiac arrest, while it was associated with higher discharges to nursing facilities. No difference in mortality was observed among non-ST-elevation myocardial infarction (NSTEMI)-rheumatoid arthritis and NSTEMI-no rheumatoid arthritis, while NSTEMI-rheumatoid arthritis was associated with lower cardiac arrest, cardiogenic shock, and hemodialysis, at the expense of higher bleeding events and discharges to nursing facilities. CONCLUSION In this nationwide analysis, we found an increase in hospitalizations for acute myocardial infarction-rheumatoid arthritis. Among patients with acute myocardial infarction, rheumatoid arthritis was independently associated with lower in-hospital mortality, particularly in cases of STEMI.

Is the History of Erectile Dysfunction a Reliable Risk Factor for New Onset Acute Myocardial Infarction? A Systematic Review and Meta-Analysis. Curr Urol 2020; 14:122-129. [PMID: 33224004 PMCID: PMC7659409 DOI: 10.1159/000499249] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2019] [Accepted: 08/19/2019] [Indexed: 11/19/2022] Open
Abstract
Acute myocardial infarction (AMI) occurs as a manifestation of coronary atherosclerotic disease. The occurrence of erectile dysfunction (ED) following AMI is well documented and this association and pathophysiology is often interrelated. Few studies have objectively assessed the diagnostic value of ED as a risk factor for AMI, in general. In this review, we aimed to better outline the diagnostic predictability of ED as a precursor for 'first/new onset' AMI. This review was performed using selective search terms, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines. The Cochrane, Embase, PubMed, Scopus and Web of Science databases were searched (September 2018). Selected studies were further assessed for relevance and quality (Critical Appraisal Skills Program tool-Oxford). Four studies [573 participants; mean 143 (SD ± 76.3604) and median 141 participants] were eligible for analysis. Meta-analysis of the studies resulted in a pooled sensitivity of 51.36% (95% CI: 47.37-55.33%). For the single study which reported true negative and false positive cases, a specificity of 76.53% (95% CI: 68.57-83.00%) was calculated. The results of this systematic review and meta-analysis suggest that a history of ED should be used as a risk factor for new onset AMI.

Abstract
AIMS To investigate the long-term prognostic value of aspiration thrombectomy in conjunction with primary percutaneous coronary intervention (PCI) compared to conventional PCI in patients with non-ST-elevation myocardial infarction (NSTEMI). METHODS In the randomized TATORT-NSTEMI (Thrombus aspiration in thrombus containing culprit lesions in non-ST-elevation myocardial infarction) trial, NSTEMI patients with thrombus containing culprit lesions were randomized to either PCI with aspiration thrombectomy or conventional PCI. The endpoint was a combination of all-cause death, reinfarction and new congestive heart failure. RESULTS From 440 patients initially randomized, outcome data were available in 432 (98.2%) patients at a median follow-up of 4.9 (interquartile range [IQR] 4.4-5.0) years. Thrombectomy was associated with a significant reduction of the combined endpoint compared to conventional PCI (19.9% vs. 30.7%, p = 0.01). This finding was primarily driven by a reduced rate of reinfarction with thrombectomy (3.4% vs. 10.3%, p = 0.01). Thrombectomy was still independently associated with the combined endpoint after multivariable adjustment (hazard ratio [HR] 0.47, 95% confidence interval [CI] 0.30-0.76, p = 0.002). Findings were consistent across all analyzed subgroups (p values for interaction all > 0.05). CONCLUSIONS In NSTEMI, thrombus aspiration is associated with favorable clinical outcome during long-term follow-up. CLINICAL TRIAL REGISTRATION NCT01612312.

Abstract
Diabetes mellitus (DM) is an important risk factor for acute myocardial infarction (AMI) and a frequent co-morbidity in patients hospitalized with AMI, being present in about 30% of cases. Although current treatment of AMI has considerably improved survival in both patients with and without DM, the presence of DM still doubles the case fatality rate during both the acute phase of AMI and at long-term follow-up. This higher mortality risk of DM patients strongly indicates a particular need for better treatment options in these patients and suggests that intensive medical treatment, prolonged surveillance, and stringent control of other risk factors should be carefully pursued and maintained for as long as possible in them.In this review, we will focus on the close association between DM and in-hospital and long-term mortality in AMI patients. We will also aim at providing current evidence on the mechanisms underlying this association and on emerging therapeutic strategies, which may reduce the traditional mortality gap that still differentiates AMI patients with DM from those without.

Abstract
AIMS To compare ischaemia-driven complete coronary revascularisation by percutaneous coronary intervention (PCI) with usual care in patients with non-ST-elevation myocardial infarction (non-STEMI) and multivessel disease (MVD). METHODS The South Limburg Myocardial Infarction (SLIM) trial (NCT03562572) is an investigator-initiated, prospective, multicentre, randomised controlled trial that compares fractional flow reserve (FFR)-guided complete revascularisation during the index procedure with usual care in non-STEMI patients with MVD. A total of 414 patients will be randomised in a 1:1 fashion. The primary endpoint is the composite of all-cause mortality, non-fatal myocardial infarction, and any revascularisation and stroke (MACCE) at 12 months. The secondary endpoints are: MACCE at 24 and 36 months, and the composite of cardiac death, myocardial infarction, any revascularisation, stroke, major bleeding and left ventricular ejection fraction below 45% at 12, 24 and 36 months. Furthermore, quality of life will be assessed by the Patient Health Questionnaire (PHQ-9) and the Short Form (36) Health Survey (SF-36) at 1 and 12 months of follow-up. CONCLUSION The SLIM trial aims to provide evidence whether FFR-guided complete revascularisation by PCI is superior to usual care with respect to clinical outcomes (major adverse cardiovascular events) in non-STEMI patients with MVD.

Abstract
PURPOSE OF REVIEW Non-ST-elevation myocardial infarction (NSTEMI) is an urgent medical condition that requires prompt application of simultaneous pharmacologic and non-pharmacologic therapies. The variation in patient clinical characteristics coupled with the multitude of treatment modalities makes optimal and timely management challenging. This review summarizes risk stratification of patients, the role and timing of revascularization, and highlights important considerations in the revascularization approach with attention to individual patient characteristics. RECENT FINDINGS The early invasive management of NSTEMI has fostered a reduction in future ischemic events. Risk calculators are helpful in determining which patients should receive early invasive management. As many patients have multivessel disease, identifying the true culprit lesion can be challenging. Special attention should be given to those at the highest risk, such as diabetics, patients with renal failure, and those with left main disease. In patients with acute coronary syndrome, the decision and mode of revascularization should carefully integrate the patient's clinical characteristics as well as the complexity of the coronary anatomy.

Percutaneous coronary intervention in patients hospitalized for non-ST-elevation myocardial infarction and the risk of postdischarge ischemic stroke at 6-month, 1-year, and 3-year follow-ups. Heart Vessels 2019; 34:1132-1139.

Abstract
Percutaneous coronary intervention (PCI) is suggested for treating patients with non-ST-elevation myocardial infarction (NSTEMI) to reduce adverse cardiovascular events. However, the short- and long-term effects of PCI on the risk of postdischarge ischemic stroke (IS) in patients hospitalized for NSTEMI remain unclear. This study investigated the association of PCI on the risk of postdischarge IS in patients hospitalized for NSTEMI at different period follow-ups. A population-based cohort study was conducted using data from Taiwan's National Health Insurance Research Database. Propensity score matching (PSM) was used to select 6079 pairs of the patients with NSTEMI treated invasively by PCI (received PCI during hospitalization) and initial conservative strategy (did not receive PCI during hospitalization) with similar baseline characteristics for evaluation. After adjustment for patients' clinical variables and the duration of dual antiplatelet therapy, PCI was associated with a decreased risk of postdischarge IS at 6-month, 1-year, and 3-year follow-ups [adjusted hazard ratio (aHR) = 0.41, 95% confidence interval (CI) = 0.26-0.67, p < 0.001; aHR = 0.61, 95% CI 0.43-0.86, p = 0.004; and aHR = 0.69, 95% CI 0.54-0.89, p = 0.005respectively]. In the patients who had a CHA2DS2-VASc score of ≥2, PCI was also associated with a decreased risk of postdischarge IS at 6-month, 1-year, and 3-year follow-ups (aHR = 0.54, 95% CI 0.36-0.83, p = 0.005; aHR = 0.72, 95% CI 0.52-1.00, p = 0.048; and aHR =0.73, 95% CI 0.58-0.91, p = 0.005, respectively). These findings suggested that PCI might reduce the risk of postdischarge IS in patients hospitalized for NSTEMI.

Abstract
Data derived from several studies suggest a better survival in smokers with acute myocardial infarction, a phenomenon referred to as the 'smoker's paradox'. We aimed to investigate the association of smoking with cardiac magnetic resonance (CMR) imaging determined infarct severity and major adverse cardiac events (MACE) defined as the occurrence of death, reinfarction, and congestive heart failure at 12 months in patients with non-ST-elevation myocardial infarction (NSTEMI) reperfused by early percutaneous coronary intervention (PCI). In this multicenter, registry study 311 NSTEMI patients underwent CMR imaging 3 (interquartile range [IQR] 2-4) days after PCI. Myocardial salvage index (MSI), infarct size (IS), and microvascular obstruction (MVO) as well as MACE rate were compared according to admission smoking status. Approximately one-third of patients were current smokers (n = 122, 39%). Smokers were significantly younger and less likely to have hypertension as compared to non-smokers (all p < 0.05). The extent of MSI (63.2, IQR 28.9-85.4 vs. 65.6, IQR 42.2-82.9, p = 0.30), and IS (7.2, IQR 2.3-15.7%LV vs. 7.0, IQR 2.2-12.4%LV, p = 0.27) did not differ significantly between smokers and non-smokers. Despite similar prevalence of MVO, MVO (%LV) was higher in smokers compared to non-smokers (2.0, IQR 0.9-4.7%LV vs. 1.2, IQR 0.7-2.2%LV, p = 0.03). MACE rates at 12 months were comparable in smokers and non-smokers (5.7% vs. 7.4%, p = 0.65). In NSTEMI patients, smoking is neither associated with increased myocardial salvage nor less severe myocardial damage. Clinical outcome at 12 months was similar in smokers and non-smokers.Trial registration NCT03516578.

Left main and/or three-vessel disease in patients with non-ST-segment elevation myocardial infarction and low-risk GRACE score: Prevalence, clinical outcomes and predictors. Rev Port Cardiol 2018; 37:911-919.

Abstract
INTRODUCTION A low-risk GRACE score identifies patients with a lower incidence of major cardiac events, however it can erroneously classify patients with severe coronary artery disease as low-risk. We assessed the prevalence, clinical outcomes and predictors of left main and/or three-vessel disease (LM/3VD) in non-ST-elevation acute myocardial infarction (NSTEMI) patients with a GRACE score of ≤108 at admission. METHODS Using data from the Portuguese Registry on Acute Coronary Syndromes, 1196 patients with NSTEMI and a GRACE score of ≤108 who underwent coronary angiography were studied. Independent predictors of LM/3VD and its impact on in-hospital complications and one-year mortality were retrospectively analyzed. RESULTS LM/3VD was present in 18.2% of patients. Its prevalence was higher in males and associated with hypertension, diabetes, previous myocardial infarction, heart failure and peripheral arterial disease (PAD). Although there were no differences in in-hospital complications, these patients had higher mortality (0.9 vs. 0.0%) and more major adverse cardiac and cerebrovascular events (MACCE) (4.1 vs. 2.5%, p=0.172), and higher one-year mortality (2.4 vs. 0.5%, p=0.005). Independent predictors of LM/3VD were age (OR 1.03; 95% CI 1.01-1.0, p=0.003), male gender (OR 2.56; 95% CI 1.56-4.17, p<0.001), heart rate (1.02; 95% CI 1.01-1.03, p<0.001), PAD (OR 3.21; 95% CI 1.47-7.00, p<0.001) and heart failure (OR 3.38; 95% CI 1.02-11.15, p=0.046). CONCLUSIONS LM/3VD was found in one in five patients. These patients had a tendency for higher in-hospital mortality and more MACCE, and higher one-year mortality. Simple clinical variables could help predict this severe coronary anatomy.

Serum neutrophil gelatinase-associated lipocalin (NGAL) concentration is independently associated with mortality in patients with acute coronary syndrome. Int J Cardiol 2018; 262:79-84. [PMID: 29622507 DOI: 10.1016/j.ijcard.2018.03.028] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/08/2017] [Revised: 02/18/2018] [Accepted: 03/06/2018] [Indexed: 12/15/2022]
Abstract
BACKGROUND Circulating neutrophil gelatinase-associated lipocalin (NGAL) concentration increases in cardiovascular disease, but the long-term prognostic value of NGAL concentration has not been evaluated in acute coronary syndrome (ACS). We examined the association between NGAL concentration and prognosis in patients with ACS after non-ST-elevation myocardial infarction (NSTEMI) or STEMI. METHODS AND RESULTS NGAL concentration was measured in blood from 1121 consecutive ACS patients (30% women, mean age 65 years) on the first morning after admission. After adjustment for 14 variables, NGAL concentration predicted long-term (median 167 months) mortality (hazard ratio [HR] 1.33, 95% confidence interval [CI] 1.10-1.61, P = 0.003) for quartile (q) 4 of NGAL concentration. NGAL concentrations also predicted long-term mortality (HR = 1.63, 95% CI 1.31-2.03, P < 0.001, N = 741) when adjusting for Global Registry of Acute Coronary Events (GRACE) score, left ventricular ejection fraction (LVEF), and pro-B-type natriuretic peptide (proBNP) and C-reactive protein (CRP) concentrations. With these adjustments, NGAL concentration predicted long-term mortality in NSTEMI patients (HR = 2.02, 95% CI 1.50-2.72, P < 0.001) but not in STEMI patients (HR = 1.32, 95% CI 0.95-1.83, P = 0.100). In all patients, the combination of NGAL concentration and GRACE score yielded an HR of 5.56 (95% CI 4.37-7.06, P < 0.001) for q4/q4 for both variables. CONCLUSION NGAL concentration in ACS is associated with long-term prognosis after adjustment for clinical confounders. Measuring circulating NGAL concentration may help to identify patients-particularly those with NSTEMI-needing closer follow-up after ACS.

Abstract
Background Non-ST elevation myocardial infarction (NSTEMI) is a common manifestation of acute coronary syndrome (ACS), but delayed diagnosis can increase mortality. In this proof of principle study, the emergency physician performed transthoracic echocardiography (TTE) on scene to determine whether NSTEMI could be correctly diagnosed pre-hospitalization. This could expedite admission to the appropriate facility and reduce the delay until initiation of correct therapy. Methods Pre-hospital TTE was performed on scene by the emergency physician in patients presenting with ACS but without ST-elevation in the initial 12-lead electrocardiography (ECG) (NSTE-ACS). A presumptive NSTEMI diagnosis was made if regional wall motion abnormalities (RWMA) were detected. These patients were admitted directly to a specialist cardiac facility. Patient characteristics and pre-admission and post-admission clinical, pre-hospital TTE data, and therapeutic measures were recorded. Results Patients with NSTE-ACS (n = 53; 72.5 ± 13.4 years of age; 23 female) were studied. The 20 patients with pre-hospital RWMA and presumptive NSTEMI, and two without RWMA were conclusively diagnosed with NSTEMI in hospital. Percutaneous coronary intervention was performed in 50% of the patients presumed to have NSTEMI immediately after admission. The RWMA seen before hospital TTE corresponded with the in-hospital ECG findings and/or the supply regions of the occluded coronary vessels seen during PCI in 85% of the cases. The diagnostic sensitivity of pre-hospital TTE for NSTEMI was 90.9% with 100% specificity. Conclusions Pre-hospital transthoracic echocardiography by the emergency physician can correctly diagnose NSTEMI in more than 90% of cases. This can expedite the initiation of appropriate therapy and could thereby conceivably reduce morbidity and mortality. Trial registration Deutsche Register klinischer Studien, DRKS00004919.

Abstract
BACKGROUND Optimal timing for an invasive strategy in non-ST elevation myocardial infarction (NSTEMI) is unclear. Whether clinical outcomes are improved with a less than two (LT2) compared with greater than two hour (GT2) invasive strategy remains to be determined. We performed a meta-analysis of randomized controlled trials (RCTs) comparing LT2 vs GT2 for NSTEMI. METHODS A comprehensive literature search for RCTs comparing LT2 vs. GT2 in NSTEMI patients was performed. Three eligible studies consisting of 1,075 patients (LT2: 537, GT2: 538) with NSTEMI were identified. Follow-up ranged from 1 to 12 months. RESULTS Time from randomization to sheath insertion ranged from 0.5-2.2 and 14.0-85.0 hours in the LT2 and GT2 groups. More percutaneous coronary interventions and fewer coronary artery bypass grafting were performed in the LT2 vs. GT2 group. There was no significant difference in all-cause mortality, myocardial infarction (MI), and major bleeding between the two groups. LT2 was numerically, but not statistically superior to GT2 at preventing recurrent ischemia/urgent revascularization/refractory ischemia. CONCLUSION Our meta-analysis found no significant difference in outcomes between less than two versus greater than two hours invasive strategy for NSTEMI. The differences observed in the mode of revascularization according to timing of catheterization deserve further study.

Does heart rate variability correlate with long-term prognosis in myocardial infarction patients treated by early revascularization? World J Cardiol 2017; 9:27-38. [PMID: 28163834 PMCID: PMC5253192 DOI: 10.4330/wjc.v9.i1.27] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/13/2016] [Revised: 11/02/2016] [Accepted: 11/29/2016] [Indexed: 02/06/2023] Open
Abstract
AIM To assess the prevalence of depressed heart rate variability (HRV) after an acute myocardial infarction (MI), and to evaluate its prognostic significance in the present era of immediate reperfusion.
METHODS Time-domain HRV (obtained from 24-h Holter recordings) was assessed in 326 patients (63.5 ± 12.1 years old; 80% males), two weeks after a complicated MI treated by early reperfusion: 208 ST-elevation myocardial infarction (STEMI) patients (in which reperfusion was successfully obtained within 6 h of symptoms in 94% of cases) and 118 non-ST-elevation myocardial infarction (NSTEMI) patients (percutaneous coronary intervention was performed within 24 h and successful in 73% of cases). Follow-up of the patients was performed via telephone interviews a median of 25 mo after the index event (95%CI of the mean 23.3-28.0). Primary end-point was occurrence of all-cause or cardiac death; secondary end-point was occurrence of major clinical events (MCE, defined as mortality or readmission for new MI, new revascularization, episodes of heart failure or stroke). Possible correlations between HRV parameters (mainly the standard deviation of all normal RR intervals, SDNN), clinical features (age, sex, type of MI, history of diabetes, left ventricle ejection fraction), angiographic characteristics (number of coronary arteries with critical stenoses, success and completeness of revascularization) and long-term outcomes were analysed.
RESULTS Markedly depressed HRV parameters were present in a relatively small percentage of patients: SDNN < 70 ms was found in 16% and SDNN < 50 ms in 4% of cases. No significant differences were present between STEMI and NSTEMI cases as regards to their distribution among quartiles of SDNN (χ2 =1.536, P = 0.674). Female sex and history of diabetes maintained a significant correlation with lower values of SDNN at multivariate Cox regression analysis (respectively: P = 0.008 and P = 0.008), while no correlation was found between depressed SDNN and history of previous MI (P = 0.999) or number of diseased coronary arteries (P = 0.428) or unsuccessful percutaneous coronary intervention (PCI) (P = 0.691). Patients with left ventricle ejection fraction (LVEF) < 40% presented more often SDNN values in the lowest quartile (P < 0.001). After > 2 years from infarction, a total of 10 patients (3.1%) were lost to follow-up. Overall incidence of MCE at follow-up was similar between STEMI and NSTEMI (P = 0.141), although all-cause and cardiac mortality were higher among NSTEMI cases (respectively: 14% vs 2%, P = 0.001; and 10% vs 1.5%, P = 0.001). The Kaplan-Meier survival curves for all-cause mortality and for cardiac deaths did not reveal significant differences between patients with SDNN in the lowest quartile and other quartiles of SDNN (respectively: P = 0.137 and P = 0.527). Also the MCE-free survival curves were similar between the group of patients with SDNN in the lowest quartile vs the patients of the other SDNN quartiles (P = 0.540), with no difference for STEMI (P = 0.180) or NSTEMI patients (P = 0.541). By the contrary, events-free survival was worse if patients presented with LVEF < 40% (P = 0.001).
CONCLUSION In our group of patients with a recent complicated MI, abnormal autonomic parameters have been found with a prevalence that was similar for STEMI and NSTEMI cases, and substantially unchanged in comparison to what reported in the pre-primary-PCI era. Long-term outcomes did not correlate with level of depression of HRV parameters recorded in the subacute phase of the disease, both in STEMI and in NSTEMI patients. These results support lack of prognostic significance of traditional HRV parameters when immediate coronary reperfusion is utilised.

Abstract
Background The association between admission hyperglycemia and adverse outcomes in patients with non-ST-segment elevation myocardial infarction (NSTEMI) undergoing percutaneous coronary intervention (PCI) has not been well studied, and the optimal plasma glucose cut-off values for prognosis for NSTEMI patients with and without diabetes have not been determined. Methods According to glucose level and diabetes status, consecutive NSTEMI patients undergoing PCI (n = 890) were divided into four groups: without diabetes mellitus (DM) and admission plasma glucose (APG) <144 or ≥144 mg/dL; or with DM and APG <180 or ≥180 mg/dL. All patients were followed up at 30 days and 3 years after discharge, and the outcomes were assessed. Results Admission hyperglycemia was found in 44 and 28% of the DM and non-DM patients, respectively. Multivariable analyses showed that the APG level was an independent predictor of 30-day and 3-year MACEs. Receiver operating characteristic curve analysis revealed that the appropriate cut-off values were 178 and 145 mg/dL for patients with and without DM, respectively, or 157 mg/dL for all patients. Conclusions Admission hyperglycemia may be used to predict 30-day and 3-year MACEs in patients with NSTEMI undergoing PCI, irrespective of diabetes status. However, the optimal admission glucose cut-off values for predicting prognosis differ for patients with or without DM.

Abstract
A parenteral anticoagulant is indicated in patients with acute coronary syndromes. Which anticoagulant should be preferred in each setting is not clearly established. Bivalirudin administration was considered in acute coronary syndromes after several clinical trials showed decreased bleeding risk with its use compared with the association of unfractionated heparin (UFH) with glycoprotein IIb/IIIa inhibitors (GPIs). Most recent data demonstrate that the bleeding benefit identified in the previous studies was not due to bivalirudin's properties but to higher bleeding incidence in the comparator arm due to the disproportional use of GPIs with heparin. This paper reviews clinical evidence on bivalirudin as anticoagulant in stable angina and acute coronary syndromes.

Abstract
BACKGROUND Takotsubo syndrome is an acute cardiovascular condition that predominantly affects women. In this study, we compared patients with takotsubo syndrome and those with acute myocardial infarction with respect to patient characteristics, angiographic findings, and short- and long-term mortality. METHODS From the Swedish Coronary Angiography and Angioplasty Registry (SCAAR) and the Register of Information and Knowledge about Swedish Heart Intensive Care Admissions (RIKS-HIA), we obtained and merged data on patients undergoing coronary angiography in Västra Götaland County in western Sweden between January 2005 and May 2013. Short- and long-term mortality in patients with takotsubo (n=302) and patients with ST-elevation myocardial infarction (STEMI, n=6595) and non-ST-elevation myocardial infarction (NSTEMI, n=8207) were compared by modeling unadjusted and propensity score-adjusted logistic and Cox proportional-hazards regression. RESULTS The proportion of the patients diagnosed with takotsubo increased from 0.16% in 2005 to 2.2% in 2012 (P<0.05); 14% of these patients also had significant coronary artery disease. Cardiogenic shock developed more frequently in patients with takotsubo than NSTEMI (adjusted OR 3.08, 95% CI 1.80-5.28, P<0.001). Thirty-day mortality was 4.1% and was comparable to STEMI and NSTEMI. The long-term risk of dying from takotsubo (median follow-up 25 months) was also comparable to NSTEMI (adjusted HR 1.01, 95% CI 0.70-1.46, P=0.955) STEMI (adjusted HR 0.83, 95% CI 0.57-1.20, P=0.328). CONCLUSIONS The proportion of acute coronary syndromes attributed to takotsubo syndrome in Western Sweden has increased over the last decade. The prognosis of takotsubo syndrome is poor, with similar early and late mortality as STEMI and NSTEMI.

Impact of fondaparinux versus enoxaparin on in-hospital bleeding and 1-year death in non-ST-segment elevation myocardial infarction. FAST-MI (French Registry of Acute ST-elevation and non-ST-elevation Myocardial Infarction) 2010. EUROPEAN HEART JOURNAL-ACUTE CARDIOVASCULAR CARE 2014; 4:211-9. [PMID: 25075006 DOI: 10.1177/2048872614544857] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 05/30/2014] [Accepted: 07/02/2014] [Indexed: 11/16/2022]
Abstract
AIMS Fondaparinux is an alternative to low molecular weight heparin (LMWH) for non-ST-elevation myocardial infarction (NSTEMI) with levels of recommendation that differ according to guidelines. The aim of this study was to assess outcomes in real world practice in NSTEMI patients participating in the French Registry of ST-elevation and non-ST-elevation Myocardial Infarction (FAST-MI) 2010 according to the use of fondaparinux, in comparison with patients receiving enoxaparin. METHODS AND RESULTS FAST-MI 2010 is a nationwide French registry that included 4,169 patients with acute myocardial infarction at the end of 2010 in 213 centres (76% of active centres in France); 1,734 had NSTEMI, with 240 receiving fondaparinux and 1,027 enoxaparin. Patients receiving enoxaparin vs. fondaparinux had essentially characteristics with a similar GRACE (Global Registry of Acute Coronary Events) score. Invasive strategy was used in 69% in both groups. In-hospital bleeding was similar with both anticoagulant strategies and 1-year survival was 94.6% and 91.7%, respectively. Using fully adjusted Cox multivariate analysis, the use of fondaparinux was not associated with a reduced risk of death (hazard ratio: 1.35; 95% confidence interval: 0.70-2.51). After propensity score matching (207 patients per group), 1-year survival was similar with both strategies. There was, however, an interaction between fondaparinux and unfractionated heparin, with higher survival in fondaparinux-treated patients who received UFH, compared with those who did not. CONCLUSIONS In this French cohort of NSTEMI patients, predominantly managed invasively, there was no evidence that fondaparinux was superior to enoxaparin as regards bleeding events or 1-year mortality (FAST-MI 2010; NCT01237418).

Early invasive versus initial conservative treatment strategies in octogenarians with UA/NSTEMI. Am J Med 2013; 126:1076-83.e1. [PMID: 24262721 DOI: 10.1016/j.amjmed.2013.07.024] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/17/2013] [Revised: 07/31/2013] [Accepted: 07/31/2013] [Indexed: 11/20/2022]
Abstract
BACKGROUND Previous studies have demonstrated improved outcomes with an early invasive strategy in patients with unstable angina/non-ST-elevation myocardial infarction (UA/NSTEMI). However, there are limited data for patients ≥80 years of age in these studies. METHODS We used the 2003-2010 Nationwide Inpatient Sample databases to identify all patients ≥80 years of age (octogenarians) with UA/NSTEMI. Multivariable logistic regression was used to compare in-hospital outcomes in octogenarians with UA/NSTEMI undergoing early invasive (coronary angiography within 48 hours of admission, with or without revascularization) versus initial conservative treatment. RESULTS Among 968,542 octogenarians with UA/NSTEMI, 806,902 (83.3%) were managed using an initial conservative approach and 161,640 (16.7%) using an early invasive strategy. Patients in the early invasive group were more likely to be younger, men, white, and had a higher prevalence of smoking, dyslipidemia, obesity, hypertension, known coronary artery disease, carotid artery disease, and peripheral vascular disease. In-hospital mortality was significantly lower in octogenarians in the early invasive group (adjusted odds ratio [OR] 0.76; 95% confidence interval [CI], 0.74-0.78). Early invasive strategy was associated with lower rates of acute ischemic stroke (adjusted OR 0.63; 95% CI, 0.60-0.66), intracranial hemorrhage (adjusted OR 0.60; 95% CI, 0.510.70), gastrointestinal bleeding (adjusted OR 0.63; 95% CI, 0.60-0.65), and shorter average length of stay (5.3 vs 5.8 days, P <.001), but higher cardiogenic shock (adjusted OR 2.14; 95% CI, 2.06-2.23) and total hospital cost (23,584 vs 13,278 USD). CONCLUSION Compared with an initial conservative approach, an early invasive strategy in octogenarians with UA/NSTEMI was associated with lower in-hospital mortality, acute ischemic stroke, intracranial hemorrhage, gastrointestinal bleeding, and shorter length of stay, but higher cardiogenic shock and total hospital cost.

Abstract
Chronic kidney disease (CKD) is associated with a high burden of coronary artery disease. In patients with acute coronary syndromes (ACS), CKD is highly prevalent and associated with poor short- and long-term outcomes. Management of patients with CKD presenting with ACS is more complex than in the general population because of the lack of well-designed randomized trials assessing therapeutic strategies in such patients. The almost uniform exclusion of patients with CKD from randomized studies evaluating new targeted therapies for ACS, coupled with concerns about further deterioration of renal function and therapy-related toxic effects, may explain the less frequent use of proven medical therapies in this subgroup of high-risk patients. However, these patients potentially have much to gain from conventional revascularization strategies used in the general population. The objective of this review is to summarize the current evidence regarding the epidemiology and the clinical and prognostic relevance of CKD in ACS patients, in particular with respect to unresolved issues and uncertainties regarding recommended medical therapies and coronary revascularization strategies.

Abstract
Both ST-segment elevation myocardial infarction and non-ST-segment elevation acute coronary syndromes (ACS) are the result of an acute thrombotic lesion obstructing blood flow in the coronary vasculature. Percutaneous treatment has shown to improve clinical outcome in this clinical setting by resolving coronary obstruction with different devices directed to restore coronary blood flow. In comparison with balloon alone angioplasty, implantation of bare metal stents reduced the rate of restenosis and cardiac events, but high rates of restenosis remained, leading to further investigations to develop drug-eluting stents with different pharmacological coatings that reduced restenosis rates and clinical events. In this review, we discuss the current treatment of ACS, reviewing recent randomized clinical trials and advances in medical treatment, including new antiplatelet agents and recent guideline recommendations.
