Zhu Z, Zhou X. Association between anaemia and long-term prognosis in patients with non-ST segment elevation myocardial infarction. Acta Cardiol 2024; 79:179-186. [PMID: 38085221 DOI: 10.1080/00015385.2023.2289718] [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: 09/27/2023] [Accepted: 11/26/2023] [Indexed: 04/18/2024]
Abstract
BACKGROUND The majority of existing studies examining the association between anaemia and the prognosis of patients with acute coronary syndrome (ACS) have focused on all patients with ACS without further categorisation. As a result, there is a dearth of research specifically exploring the relationship between anaemia and the long-term prognosis of patients with non-ST segment elevation myocardial infarction (NSTEMI). To address this gap, this study aimed to investigate the correlation between anaemia and the long-term prognosis of NSTEMI patients. METHODS This study included 482 NSTEMI patients who underwent percutaneous coronary intervention (PCI) at the First Affiliated Hospital of Chongqing Medical University from September 1, 2016 to May 31, 2022, and the patients were classified into the major adverse cardiovascular events (MACE) group and non-MACEs group according to whether or not they had developed MACE as of February 28, 2023 at follow-up.COX regression analysis was used to assess whether anaemia was an independent factor influencing MACE occurrence in patients with NSTEMI. Receiver operating characteristic (ROC) curve analysis was conducted to determine if haemoglobin levels could enhance the predictive capacity of the Global Registry of Acute Coronary Events (GRACE) score for the prognosis of NSTEMI patients. Haemoglobin levels were categorised into two groups based on the optimal cut-off value and transformed into binary data. The log-rank test was performed to compare the two groups, and a risk function was plotted. RESULTS During a median follow-up period of 31 months, 124 (25.7%) MACE were identified. Univariate and multivariate COX regression analyses revealed that sex, age, smoking history, diabetes, creatinine, erythrocyte count, and haemoglobin level were independent risk factors that significantly influenced survival time. Subsequently, ROC curve analysis was performed to evaluate the predictive accuracy of specific variables. When the cut-off value for the decline ratio of haemoglobin was set at 128.50, the area under the curve (AUC) was determined to be 0.604, with a sensitivity of 0.403 and a specificity of 0.771. Similarly, setting the cut-off value for the reduction ratio of the GRACE score at 141.5 yielded an AUC of 0.700, with a sensitivity of 0.645 and a specificity of 0.709. Furthermore, when the cut-off value for the predicted probability of haemoglobin combined with the GRACE score was 0.270, the AUC was calculated as 0.702, with a sensitivity of 0.677 and a specificity of 0.696. CONCLUSION Haemoglobin levels were identified as an independent factor influencing the survival duration of patients with NSTEMI.

Abstract
Strong inflammatory indicators such as C-reactive protein (CRP), high-sensitivity CRP (hsCRP), and hematological indices, including platelet to lymphocyte ratio (PLR), neutrophil to lymphocyte ratio (NLR), hematocrit (HCT), and red blood cell distribution width (RDW), may be related with contrast-induced nephropathy (CIN). Our meta-analysis aimed at exploring the relationship between these indicators and CIN incidence among patients undergoing coronary intervention. Clinical studies were retrieved from the electronic databases of PubMed, EMBASE, Google Scholar, Clinical Trials, and Science Direct from their inception to June 3, 2020. Meta-analysis was performed on pooled eligible studies. Finally, 26 studies involving 29 454 patients were included. Pooled analysis revealed that patients with higher CRP (odds ratio [OR] = 1.06, 95% CI: 1.01-1.12, P = .02), hsCRP (OR = 1.03, 95% CI: 1.01-1.06, P = .004), NLR (OR = 1.11, 95% CI: 1.01-1.20, P = .02), RDW (OR = 1.35, 95% CI: 1.19-1.53, P < .001), and lower HCT (OR = 0.94, 95% CI: 0.92-0.97, P = .003) all exhibited significantly higher CIN rates, but there was no significant association between PLR and CIN risk (OR = 1.12, 95% CI: 0.99-1.26, P = .07). Pre-angiography CRP/hsCRP and some hematological indices are associated with CIN.

Abstract
Transcatheter aortic valve replacement (TAVR) is well established for treating patients with severe aortic stenosis considered at intermediate to high surgical risk. Blood disorders such as anemia, thrombocytopenia, and acquired type 2A von Willebrand disease are relatively frequent in TAVR candidates, and multiple studies to date have highlighted their potential clinical association with mortality and/or bleeding complications post-TAVR. The present review provides an overview of various blood disorders observed pre- and post-TAVR, with special focus on their incidence, etiology, clinical association, and management.

Abstract
Anemia is common in patients undergoing percutaneous coronary intervention (PCI), and current guidelines fail to offer recommendations for its management. This review aims to examine the relation between baseline anemia and mortality, major adverse cardiovascular events (MACE), and major bleeding in patients undergoing PCI. We searched MEDLINE and EMBASE for studies that evaluated mortality and adverse outcomes in anemic and nonanemic patients who underwent PCI. Data were collected on study design, participant characteristics, definition of anemia, follow-up, and adverse outcomes. Random effects meta-analysis of risk ratios was performed using inverse variance method. A total of 44 studies were included in the review with 230,795 participants. The prevalence of baseline anemia was 26,514 of 170,914 (16%). There was an elevated risk of mortality and MACE with anemia compared with no anemia-pooled risk ratio (RR) 2.39 (2.02 to 2.83), p <0.001 and RR 1.51 (1.34 to 1.71), p <0.001, respectively. The risk of myocardial infarction and bleeding with anemia compared with no anemia was elevated, pooled RR 1.33 (1.07 to 1.65), p = 0.01 and RR 1.97 (1.03 to 3.77), p <0.001, respectively. The risk of mortality per unit incremental decrease in hemoglobin (g/dl) was RR 1.19 (1.09 to 1.30), p <0.001 and the risk of mortality, MACE, and reinfarction per 1 unit incremental decrease in hematocrit (%) was RR 1.07 (1.05 to 1.10), p = 0.04, RR 1.09 (1.08 to 1.10) and RR 1.06 (1.03 to 1.10), respectively. The prevalence of anemia in contemporary cohorts of patients undergoing PCI is significant and is associated with significant increases in postprocedural mortality, MACE, reinfarction, and bleeding. The optimal strategy for the management of anemia in such patients remains uncertain.

Abstract
BACKGROUND Data focused on the ischemic events and bleeding events are still limited. We systematically reviewed the current available literature to investigate whether anemia increase incidence of long-term ischemic events and long-term bleeding events in patients undergoing PCI. METHODS PubMed and Embase were searched for case-control studies regarding the impact of anemia on long-term outcomes in patients undergoing percutaneous coronary intervention (PCI). The primary outcome was long-term ischemic events and long-term bleeding events. Mantel-Haenszel method with random effects model or fixed effects model was used to calculate pooled odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS Seventeen studies involving 68,528 patients (17,123 anemic patients and 51,405 non-anemic patients) were included. Pooled analysis suggested that anemic patients were at higher risk for long-term composite ischemic events (OR: 1.95, 95% CI, 1.21-3.14, P<0.01, I(2)=84%), long-term reinfarction (0R: 1.63, 95% CI, 1.16-2.28, P<0.01, I(2)=82%) and long-term bleeding events (OR: 2.89, 95% CI, 1.68-4.98, P<0.001, I(2)=89%). Anemia was also associated with long-term mortality (OR: 3.20, 95% CI, 2.72-3.75, P<0.01, I(2)=65%) and major adverse cardiac events (MACE) (OR: 2.06, 95% CI, 1.48-2.86, P<0.01, I(2)=91%). CONCLUSIONS Anemic patients undergoing PCI are at higher risk for both long-term ischemic events and bleeding events, and also at higher risk for long-term mortality and MACE. There's a need for further clarification and consistency regarding dosage, timing and duration of antithrombotic therapy for the prevention of ischemic events and bleeding events in anemic patients.

Impact of Anemia and Dual Antiplatelet Therapy on Mortality in Patients Undergoing Percutaneous Coronary Intervention with Drug-Eluting Stents. Sci Rep 2015; 5:17213. [PMID: 26601689 PMCID: PMC4658638 DOI: 10.1038/srep17213] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2015] [Accepted: 10/09/2015] [Indexed: 01/21/2023] Open
Abstract
The objective was to assess the impact of baseline anemia on all-cause mortality and whether 12-month dual antiplatelet therapy (DAPT) affects 1-year mortality linked to anemia in patients after percutaneous coronary intervention (PCI) with drug-eluting stents (DES). 4109 enrolled patients divided into three groups based on their pre-procedural hemoglobin (Hb) level: Hb < 100 mg/L represented moderate-severe anemia; 100 mg/L ≤ Hb < 120 mg/L for women and 100 mg/L ≤ Hb < 130 mg/L for men represented mild anemia; Hb ≥ 20 mg/L for women and Hb ≥ 130 mg/L for men represented no anemia. DAPT medications were prescribed when patients were discharged. There were significant differences in 30-day and 1-year mortality between moderate-severe anemia and no anemia patients (HR 8.05, 95% CI 1.46 to 44.33, P = 0.017; HR 3.93, 95% CI 1.11 to 13.98, P = 0.034), and in long-term mortality between anemia and no anemia groups (HR 1.82, 95% CI 1.17 to 2.83, P = 0.008 for mild anemia; HR 3.19,95% CI 1.29 to 7.86, P = 0.012 for moderate-severe anemia). There was not significant interaction between 12-month DAPT and anemia on mortality in anemic patients (P for interaction > 0.05). Anemia shows association with increased all-cause mortality in patients undergoing PCI. Twelve-month DAPT does not show synergy with anemia to increase the risk of all-cause 1-year mortality in anemic patients after PCI.

Abstract
PURPOSE Cardiac comorbidities in patients undergoing amputation due to diabetic foot ulcer are associated with high mortality rates. The authors investigated whether preanesthetic echocardiographic and laboratory values can predict inhospital mortality in type II diabetes patients undergoing major lower limb amputation under spinal anesthesia. METHODS The archived medical records of 215 patients were retrospectively reviewed. Demographic data and preoperative laboratory and transthoracic echocardiographic values were analyzed by multivariate logistic regression for factors independently associated with inhospital mortality. RESULTS Of the 215 patients, 12 died in hospital after amputation. Preoperative hemoglobin level (hazard ratio, 0.082; 95% confidence interval, 0.013-0.509; P = .007) and left ventricular ejection fraction (hazard ratio, 0.874; 95% confidence interval, 0.779- 0.981; P = .023) were found to be significant predictors of inhospital mortality. CONCLUSIONS Preoperative hemoglobin level and left ventricular ejection fraction are highly correlated with inhospital mortality in type II diabetes patients undergoing major lower extremity amputation under spinal anesthesia.

Abstract
Baseline anemia is associated with transfusions and increased risk of mortality in patients who underwent cardiac surgery and percutaneous coronary intervention. The impact of blood transfusions in anemic patients who underwent transcatheter aortic valve implantation (TAVI) remains unclear. All patients who underwent transfemoral TAVI at our institution were retrospectively included. We determined the effect of blood transfusions on short- and long-term mortality and its interaction with baseline hemoglobin levels and bleeding complications. Additionally, we evaluated baseline hemoglobin effect on mortality. A total of 332 patients were included. All patients (99%) except 2 (1%) met the definition for anemia. Of the 332 patients, 124 (37%) received a blood transfusion and 208 (63%) did not. Blood transfusions were associated with increased in-hospital (p <0.001), 30-day (p <0.001), and 1-year (28% vs 13%, p = 0.001) mortality; however, after a landmark analysis, the effect of blood transfusion on mortality was only seen within 30 days of the procedure (p = 0.001). The increased risk of mortality associated with blood transfusion was present after multivariate adjustment at 30 days (hazard ratio 3.59 [1.04 to 12.4]; p = 0.04). Major vascular complications were a correlate for short- and long-term death. In contrast, baseline hemoglobin level and bleeding complications were not independently associated with mortality. The p value for interaction was not significant between transfusion and hemoglobin level and for transfusion and bleeding complication and transfusion and major vascular complication. In conclusion, the presence of anemia in patients who underwent TAVI does not affect mortality. Transfusion is a correlate of all-cause mortality in this patient population and should be used with caution.

Abstract
There are limited data on the impact of anemia on clinical outcomes in unstable angina and non-ST-segment elevation myocardial infarction treated with an early invasive strategy. We sought to determine the short- and long-term clinical events among patients with and without anemia enrolled in the Acute Catheterization and Urgent Intervention Triage Strategy (ACUITY) trial. Anemia was defined as baseline hemoglobin of <13 g/dl for men and <12 g/dl for women. The primary end points were composite ischemia (death, myocardial infarction, or unplanned revascularization for ischemia) and major bleeding assessed in-hospital, at 1 month, and at 1 year. Among the 13,819 patients in the ACUITY trial, information regarding anemia was available in 13,032 (94.3%), 2,199 of whom (16.9%) had anemia. Patients with anemia compared with those without anemia had significantly increased adverse event rates in-hospital (composite ischemia 6.6% vs 4.8%, p = 0.0004; major bleeding 7.3% vs 3.3%, p <0.0001), at 1 month (composite ischemia 10% vs 7.2%, p <0.0001, major bleeding 8.8% vs 3.9%, p <0.0001), and 1 year (composite ischemia 21.7% vs 15.3%, p <0.0001). Anemia was an independent predictor of death at 1 year (hazard ratio 1.77, 95% confidence interval [CI] 1.29 to 2.44, p = 0.0005). Composite ischemia was significantly more common among patients who developed in-hospital non-coronary artery bypass surgery major bleeding compared with those who did not (anemic patients 1-year relative risk 2.19, 95% CI 1.67 to 2.88, p <0.0001; nonanemic patients relative risk 2.16, 95% CI 1.76 to 2.65, p <0.0001). In conclusion, in the ACUITY trial, baseline anemia was strongly associated with adverse early and late clinical events, especially in those who developed major bleeding.

Abstract
BACKGROUND Anaemia is associated with an increased risk for morbidity and mortality in ST-elevation myocardial infarction (STEMI) patients. While several physiological mechanisms have been proposed to explain this association, decreased receipt of guidelines-based care may also contribute. We examined the relationship between admission haemoglobin (Hgb) level, receipt of ACC/AHA guidelines-based treatments, and in-hospital outcomes among STEMI patients. We also evaluated whether administration of these treatments modified the association between anaemia and in-hospital mortality in this group. METHODS AND RESULTS We analysed data from 92,686 patients diagnosed with STEMI included in the NCDR ACTION Registry-GWTG database from January 2007 to March 2011. Patients were stratified by initial Hgb value: 83.1% (n=77,035) were classified as non-anaemic (Hgb >13.0 g/dl for men, >12.0 g/dl for women), 11.6% (n=10,710) as mildly anaemic (11.1-13.0 g/dl for men, 11.1-12.0 g/dl for women), 4.4% (n=4059) as moderately anaemic (9.1-11.0 g/dl), and 1.0% (n=882) as severely anaemic (<9.0 g/dl). Anaemia was associated with a significantly increased prevalence of other baseline comorbidities and decreased odds of receiving several class I recommended pharmacological treatments (heparin, beta-blockers, and angiotensin-converting enzyme inhibitors, p<0.01). The overall use of reperfusion therapy (fibrinolytic therapy and/or percutaneous coronary intervention) was also lower in anaemic vs. non-anaemic patients (p<0.01). Anaemia was associated higher in-hospital mortality risk, which remained significant after adjustment for use of guidelines-recommended therapies and interventions (p<0.01). CONCLUSIONS In a national sample of STEMI patients, anaemia on presentation was associated with decreased receipt of ACC/AHA guidelines-based care and higher in-hospital mortality. However, the higher mortality rates could not be fully explained by differences in in-hospital treatment.

Abstract
Background—
Anemia is frequent among patients with cardiovascular disease and adversely affects prognosis. The objective of this analysis was to assess the impact of anemia on long-term clinical outcomes among patients undergoing percutaneous coronary intervention (PCI) with the unrestricted use of drug-eluting stents (DES).
Methods and Results—
Between April 2002 to March 2009, 6528 consecutive patients underwent PCI with the unrestricted use of DES. Among patients with anemia according to the criteria by the World Health Organization (WHO) (hemoglobin <130 g/L for men and <120 g/L for women, respectively) patients below the 25
th
percentile separately for men and women were defined to have severe anemia. We compared clinical outcomes among patients with severe anemia and no/mild anemia during long-term follow-up through 4 years. Whereas 21.6% of patients were found to have anemia according to the WHO definition, 347 patients (5.5%) had severe anemia (mean hemoglobin, 98±11 g/L). Severe anemia was more prevalent among the elderly (
P
<0.001), diabetics (
P
<0.001), and patients with chronic kidney disease (
P
<0.001). In adjusted analyses, severe anemia was associated with an increased risk of death (hazard ratio, 1.86; 95% confidence interval, 1.37–2.52;
P
<0.0001), cardiac death (hazard ratio, 2.32; 95% confidence interval, 1.57–3.43;
P
<0.0001), and myocardial infarction (hazard ratio, 2.02; 95% confidence interval, 1.36–3.01;
P
=0.00054) as compared with no/mild anemia without significant interaction across sexes (
P
=0.86) and acute coronary syndromes (
P
=0.61) and a trend toward a particularly high risk of mortality among anemic patients <65 years of age (
P
=0.07). Severe anemia resulted in a greater risk of overall definite stent thrombosis (hazard ratio, 2.59; 95% confidence interval, 1.48–4.54;
P
=0.00089).
Conclusions—
Severe anemia is common among patients undergoing PCI with the unrestricted use of DES and adversely affects long-term prognosis, including survival.

A novel percutaneous coronary intervention risk score to predict one-year mortality. Am J Cardiol 2010; 106:641-5.

Abstract
Clinical and angiographic risk factors associated with adverse outcomes after percutaneous coronary intervention (PCI) have been included in previous validated risk scores. Complications after PCI are known to increase mortality and morbidity but have not been included in any model. Records of 6,932 consecutive patients who underwent PCI from 2000 to 2005 were reviewed. Patients presenting with cardiogenic shock were excluded. Logistic regression and bootstrap methods were used to build an integer risk score for estimating risk of death at 1 year after PCI using baseline, angiographic, and procedural characteristics and postprocedural complications. This risk score was validated in a set of consecutive patients who underwent PCI from 2006 to 2007. The following 8 variables were significantly correlated with outcome: older age, history of diabetes mellitus, chronic renal failure, heart failure, left main coronary artery disease, lower baseline hematocrit, greater hematocrit decrease after PCI, and Thrombolysis In Myocardial Infarction grade <3 flow after PCI. In the validation population (n = 973), average receiver operating characteristic curve area was 0.836. In conclusion, we developed and validated a simple integer risk score, including postprocedural variables that closely predict long-term mortality after PCI. This model emphasizes the significant impact of complications occurring after PCI on long-term outcomes.

Abstract
Anemia and major bleeding are independent predictors of outcomes after acute coronary syndromes and percutaneous coronary intervention (PCI). Although the transradial approach reduces the incidence of bleeding, the hemoglobin changes after transradial PCI have not been defined. We serially assessed the hemoglobin values before and after transradial PCI and evaluated the effect of hemoglobin changes on outcomes. In the EArly Discharge After Transradial Stenting of CoronarY Arteries (EASY) trial, 1,348 patients underwent transradial PCI. All patients received aspirin, clopidogrel, and a bolus of abciximab before PCI. The hemoglobin values were assessed immediately before and 4 to 6 hours and 12 to 24 hours after PCI. The major adverse cardiac events (death, myocardial infarction, and target vessel revascularization) were assessed < or =3 years after PCI. According to the World Health Organization classification, 206 patients (15%) had anemia before PCI and 410 (30%) developed anemia within 24 hours after PCI. A mean hemoglobin decrease of 0.6 +/- 1.0 g/dl occurred within 24 hours after PCI. At 30 days, the major adverse cardiac events were significantly increased when the hemoglobin decrease within 24 hours after PCI was >3 g/dl (p = 0.0002). Patients with anemia within 24 hours after PCI had significantly more major adverse cardiac events at 30 days, 6 months, 1 year, and 3 years than patients without anemia (log-rank p = 0.0044). After adjustment for differences in the baseline characteristics, anemia within 24 hours after PCI remained an independent predictor of major averse cardiac events at 3 years (hazard ratio 1.30, 95% confidence interval 1.01 to 1.67, p = 0.045). In conclusion, within 24 hours after transradial PCI with maximal antiplatelet therapy, only a mild hemoglobin decrease was observed. The choice of a hemoglobin decrease >3 g/dl after PCI as a cutoff value for current definitions of major bleeding in modern PCI trials appears reasonable. Measures to prevent anemia and blood loss during PCI remain to be further studied.
