Effect of Erythropoietin in patients with acute myocardial infarction: five-year results of the REVIVAL-3 trial.

ABSTRACT: Erythropoietin (EPO) has been suggested to promote cardiac repair after MI. However, the randomized, double-blind, placebo controlled REVIVAL-3 trial showed that short term high dose EPO in timely reperfused myocardium does not improve left ventricular ejection fraction after 6 months. Moreover, the study raised safety concerns due to a trend towards a higher incidence of adverse clinical events as well as a increase in neointima formation after treatment with EPO. The present study therefore aimed to assess the 5-year clinical outcomes.After successful reperfusion 138 patients with STEMI were randomly assigned to receive epoetin beta (3.33×104 U, n?=?68) or placebo (n?=?70) immediately, 24 and 48 h after percutaneous coronary intervention. The primary outcome of the present study- the combined incidence of MACE 5 years after randomization - occurred in 25% of the patients assigned to epoetin beta and 17% of the patients assigned to placebo (RR 1.5; 95% CI 0.8-3.5; p?=?0.26). Target lesion revascularization was required in 15 patients (22.1%) treated with epoetin-ß and 9 patients (12.9%) treated with placebo (p?=?0.15). Analysis of patients in the upper and lower quartile of baseline hemoglobin as an indirect estimate of endogenous erythropoietin levels revealed no significant impact of endogenous erythropoietin on efficiency of exogen administered epoetin-ß in terms of death and MACE.These long-term follow-up data show that epoetin beta does not improve clinical outcomes of patients with acute myocardial infarction.URL www.clinicaltrials.gov ; Unique identifier NCT00390832; trial registration date October 19th 2006.

Project description:BackgroundInflammation is a key factor of myocardial damage in reperfused ST-segment-elevation myocardial infarction. We hypothesized that colchicine, a potent anti-inflammatory agent, may reduce infarct size (IS) and left ventricular (LV) remodeling at the acute phase of ST-segment-elevation myocardial infarction.MethodsIn this double-blind multicenter trial, we randomly assigned patients admitted for a first episode of ST-segment-elevation myocardial infarction referred for primary percutaneous coronary intervention to receive oral colchicine (2-mg loading dose followed by 0.5 mg twice a day) or matching placebo from admission to day 5. The primary efficacy outcome was IS determined by cardiac magnetic resonance imaging at 5 days. The relative LV end-diastolic volume change at 3 months and IS at 3 months assessed by cardiac magnetic resonance imaging were among the secondary outcomes.ResultsWe enrolled 192 patients, 101 in the colchicine group and 91 in the control group. At 5 days, the gadolinium enhancement-defined IS did not differ between the colchicine and placebo groups with a mean of 26 interquartile range (IQR) [16-44] versus 28.4 IQR [14-40] g of LV mass, respectively (P=0.87). At 3 months follow-up, there was no significant difference in LV remodeling between the colchicine and placebo groups with a +2.4% (IQR, -8.3% to 11.1%) versus -1.1% (IQR, -8.0% to 9.9%) change in LV end-diastolic volume (P=0.49). Infarct size at 3 months was also not significantly different between the colchicine and placebo groups (17 IQR [10-28] versus 18 IQR [10-27] g of LV mass, respectively; P=0.92). The incidence of gastrointestinal adverse events during the treatment period was greater with colchicine than with placebo (34% versus 11%, respectively; P=0.0002).ConclusionsIn this randomized, placebo-controlled trial, oral administration of high-dose colchicine at the time of reperfusion and for 5 days did not reduce IS assessed by cardiac magnetic resonance imaging.

Project description:Background Hospitalization for acute myocardial infarction (MI) in the United States is both common and expensive, but those features alone provide little insight into cost-saving opportunities. Methods and Results To understand the cost drivers during hospitalization for acute MI and in the following year, we prospectively studied 11 969 patients with acute MI undergoing percutaneous coronary intervention at 233 US hospitals (2010-2013) from the TRANSLATE-ACS (Treatment With ADP Receptor Inhibitors: Longitudinal Assessment of Treatment Patterns and Events After Acute Coronary Syndrome) registry. Baseline costs were collected in a random subset (n=4619 patients, 54% ST-segment-elevation MI [STEMI]), while follow-up costs out to 1 year were collected for all patients. The mean index length of stay was 3.1 days (for both STEMI and non-STEMI) and mean intensive care unit length of stay was 1.2 days (1.4 days for STEMI and 1.0 days for non-STEMI). Index hospital costs averaged $18 931 ($19 327 for STEMI, $18 465 for non-STEMI), with 45% catheterization laboratory-related and 20% attributable to postprocedure hospital stay. Patient factors, including severity of illness and extent of coronary disease, and hospital characteristics, including for profit status and geographic region, identified significant variations in cost. Intensive care was used for 53% of non-STEMI and increased costs by $3282. Postdischarge 1-year costs averaged $8037, and 48% of patients were rehospitalized (half within 2 months and 57% with a cardiovascular diagnosis). Conclusions While much of the cost of patients with acute MI treated with percutaneous coronary intervention is probably not modifiable by the care team, cost reductions are still possible through quality-preserving practice efficiencies, such as need-based use rather than routine use of intensive care unit for patients with stable non-STEMI.

Project description:BackgroundOral antiplatelet therapy is the cornerstone of treatment for acute myocardial infaction (AMI). However, detailed usage data on oral antiplatelet therapy are lacking.MethodsUsing data from a nationally representative sample of patients with AMI, the detailed usage of oral antiplatelet therapy was analyzed in 40,202 consecutive eligible patients.ResultsThe proportions of patients with AMI taking loading doses of aspirin and P2Y12 inhibitors were relatively low (62.2% and 63.6%, respectively), whereas approximately 90% of patients received maintenance doses of aspirin, P2Y12 inhibitors, and dual antiplatelet therapy. The proportions of patients taking loading doses of aspirin and P2Y12 inhibitors gradually decreased with age. Male sex, an educational level of at least college, an interval from onset to treatment of < 24 h, and primary PCI use were associated with a higher proportion of patients taking a loading dose of antiplatelet therapy, whereas those receiving conservative treatment had a lower rate of antiplatelet use (all P < 0.05). The proportion of patients taking loading doses of aspirin was highest in the western region, and that of patients taking loading doses of P2Y12 inhibitors was highest in the eastern region (P < 0.05). In addition, 76.7% of patients with ST-elevation MI and 91% of patients with non-ST-elevation MI received 300-mg loading dose of clopidogrel.ConclusionsThe proportion of patients with AMI receiving loading doses of aspirin and P2Y12 inhibitors during hospitalization was relatively low, and this rate was affected by many factors, such as age, sex, educational level, region of residence, and the interval from onset to treatment. The underutilization of guideline-based P2Y12 inhibitors was also problematic. Hence, quality improvement initiatives are needed to enhance adherence to guidelines to improve consistent use of oral antiplatelet therapy.

Project description:CONTEXT:Acute ST-segment elevation myocardial infarction (STEMI) is a leading cause of morbidity and mortality. In experimental models of MI, erythropoietin reduces infarct size and improves left ventricular (LV) function. OBJECTIVE:To evaluate the safety and efficacy of a single intravenous bolus of epoetin alfa in patients with STEMI. DESIGN, SETTING, AND PATIENTS:A prospective, randomized, double-blind, placebo-controlled trial with a dose-escalation safety phase and a single dose (60,000 U of epoetin alfa) efficacy phase; the Reduction of Infarct Expansion and Ventricular Remodeling With Erythropoietin After Large Myocardial Infarction (REVEAL) trial was conducted at 28 US sites between October 2006 and February 2010, and included 222 patients with STEMI who underwent successful percutaneous coronary intervention (PCI) as a primary or rescue reperfusion strategy. INTERVENTION:Participants were randomly assigned to treatment with intravenous epoetin alfa or matching saline placebo administered within 4 hours of reperfusion. MAIN OUTCOME MEASURE:Infarct size, expressed as percentage of LV mass, assessed by cardiac magnetic resonance (CMR) imaging performed 2 to 6 days after study medication administration (first CMR) and again 12 ± 2 weeks later (second CMR). RESULTS:In the efficacy cohort, the infarct size did not differ between groups on either the first CMR scan (n = 136; 15.8% LV mass [95% confidence interval {CI}, 13.3-18.2% LV mass] for the epoetin alfa group vs 15.0% LV mass [95% CI, 12.6-17.3% LV mass] for the placebo group; P = .67) or on the second CMR scan (n = 124; 10.6% LV mass [95% CI, 8.4-12.8% LV mass] vs 10.4% LV mass [95% CI, 8.5-12.3% LV mass], respectively; P = .89). In a prespecified analysis of patients aged 70 years or older (n = 21), the mean infarct size within the first week (first CMR) was larger in the epoetin alfa group (19.9% LV mass; 95% CI, 14.0-25.7% LV mass) than in the placebo group (11.7% LV mass; 95% CI, 7.2-16.1% LV mass) (P = .03). In the safety cohort, of the 125 patients who received epoetin alfa, the composite outcome of death, MI, stroke, or stent thrombosis occurred in 5 (4.0%; 95% CI, 1.31%-9.09%) but in none of the 97 who received placebo (P = .04). CONCLUSIONS:In patients with STEMI who had successful reperfusion with primary or rescue PCI, a single intravenous bolus of epoetin alfa within 4 hours of PCI did not reduce infarct size and was associated with higher rates of adverse cardiovascular events. Subgroup analyses raised concerns about an increase in infarct size among older patients. TRIAL REGISTRATION:clinicaltrials.gov Identifier: NCT00378352.
