TL;DR: Bleeding complications have been associated with an increased risk of subsequent adverse outcomes, including MI, stroke, stent thrombosis, and death, in patients with ACS and in those undergoing percutaneous coronary intervention (PCI) as well as in the long-term antithrombotic setting.
Abstract: Advances in antithrombotic therapy, along with an early invasive strategy, have reduced the incidence of recurrent ischemic events and death in patients with acute coronary syndromes (ACS; unstable angina, non–ST-segment–elevation myocardial infarction [MI], and ST-segment–elevation MI).1,–,4 However, the combination of multiple pharmacotherapies, including aspirin, platelet P2Y12 inhibitors, heparin plus glycoprotein IIb/IIIa inhibitors, direct thrombin inhibitors, and the increasing use of invasive procedures, has also been associated with an increased risk of bleeding.

Bleeding complications have been associated with an increased risk of subsequent adverse outcomes, including MI, stroke, stent thrombosis, and death, in patients with ACS and in those undergoing percutaneous coronary intervention (PCI),5,–,10 as well as in the long-term antithrombotic setting.11,12 Thus, balancing the anti-ischemic benefits against the bleeding risk of antithrombotic agents and interventions is of paramount importance in assessing new therapies and in managing patients. Prior randomized trials comparing antithrombotic agents suggest that a reduction in bleeding events is associated with improved survival.13,14
Because prevention of major bleeding may represent an important step in improving outcomes by balancing safety and efficacy in the contemporary treatment of ACS, bleeding events have been systematically identified as a crucial end point for the assessment of the safety of drugs during the course of randomized clinical trials, and are an important aspect of the evaluation of new devices and interventional therapies.15 Unlike ischemic clinical events (eg, cardiac death, MI, stent thrombosis), for which there is now general consensus on end-point definitions,16,17 there is substantial heterogeneity among the many bleeding definitions currently in use. Lack of standardization makes it difficult to optimally organize key clinical trial processes such as adjudication, and even more difficult to interpret relative …

TL;DR: The lower rate of local vascular complications may be a reason to use the radial approach in patients with acute coronary syndromes who were undergoing coronary angiography with possible intervention.

TL;DR: In patients with acute coronary syndrome undergoing invasive management, radial as compared with femoral access reduces net adverse clinical events, through a reduction in major bleeding and all-cause mortality.

TL;DR: The AABB developed this guideline to provide clinical recommendations about hemoglobin concentration thresholds and other clinical variables that trigger RBC transfusions in hemodynamically stable adults and children.
Abstract: Description: Although approximately 85 million units of red blood cells (RBCs) are transfused annually worldwide, transfusion practices vary widely The AABB (formerly, the American Association of Blood Banks) developed this guideline to provide clinical recommendations about hemoglobin concentration thresholds and other clinical variables that trigger RBC transfusions in hemodynamically stable adults and children Methods: These guidelines are based on a systematic review of randomized clinical trials evaluating transfusion thresholds We performed a literature search from 1950 to February 2011 with no language restrictions We examined the proportion of patients who received any RBC transfusion and the number of RBC units transfused to describe the effect of restrictive transfusion strategies on RBC use To determine the clinical consequences of restrictive transfusion strategies, we examined overall mortality, nonfatal myocardial infarction, cardiac events, pulmonary edema, stroke, thromboembolism, renal failure, infection, hemorrhage, mental confusion, functional recovery, and length of hospital stay Recommendation 1: The AABB recommends adhering to a restrictive transfusion strategy (7 to 8 g/dL) in hospitalized, stable patients (Grade: strong recommendation; high-quality evidence) Recommendation 2: The AABB suggests adhering to a restrictive strategy in hospitalized patients with preexisting cardiovascular disease and considering transfusion for patients with symptoms or a hemoglobin level of 8 g/dL or less (Grade: weak recommendation; moderate-quality evidence) Recommendation 3: The AABB cannot recommend for or against a liberal or restrictive transfusion threshold for hospitalized, hemodynamically stable patients with the acute coronary syndrome (Grade: uncertain recommendation; very low-quality evidence) Recommendation 4: The AABB suggests that transfusion decisions be influenced by symptoms as well as hemoglobin concentration (Grade: weak recommendation; low-quality evidence)

TL;DR: Blood transfusion in the setting of acute coronary syndromes is associated with higher mortality, and this relationship persists after adjustment for other predictive factors and timing of events.
Abstract: ContextIt is unclear if blood transfusion in anemic patients with acute coronary
syndromes is associated with improved survival.ObjectiveTo determine the association between blood transfusion and mortality
among patients with acute coronary syndromes who develop bleeding, anemia,
or both during their hospital course.Design, Setting, and PatientsWe analyzed 24 112 enrollees in 3 large international trials of
patients with acute coronary syndromes (the GUSTO IIb, PURSUIT, and PARAGON
B trials). Patients were grouped according to whether they received a blood
transfusion during the hospitalization. The association between transfusion
and outcome was assessed using Cox proportional hazards modeling that incorporated
transfusion as a time-dependent covariate and the propensity to receive blood,
and a landmark analysis.Main Outcome MeasureThirty-day mortality.ResultsOf the patients included, 2401 (10.0%) underwent at least 1 blood transfusion
during their hospitalization. Patients who underwent transfusion were older
and had more comorbid illness at presentation and also had a significantly
higher unadjusted rate of 30-day death (8.00% vs 3.08%; P<.001), myocardial infarction (MI) (25.16% vs 8.16%; P<.001), and death/MI (29.24% vs 10.02%; P<.001)
compared with patients who did not undergo transfusion. Using Cox proportional
hazards modeling that incorporated transfusion as a time-dependent covariate,
transfusion was associated with an increased hazard for 30-day death (adjusted
hazard ratio [HR], 3.94; 95% confidence interval [CI], 3.26-4.75) and 30-day
death/MI (HR, 2.92; 95% CI, 2.55-3.35). In the landmark analysis that included
procedures and bleeding events, transfusion was associated with a trend toward
increased mortality. The predicted probability of 30-day death was higher
with transfusion at nadir hematocrit values above 25%.ConclusionsBlood transfusion in the setting of acute coronary syndromes is associated
with higher mortality, and this relationship persists after adjustment for
other predictive factors and timing of events. Given the limitations of post
hoc analysis of clinical trials data, a randomized trial of transfusion strategies
is warranted to resolve the disparity in results between our study and other
observational studies. We suggest caution regarding the routine use of blood
transfusion to maintain arbitrary hematocrit levels in stable patients with
ischemic heart disease.
