Bleeding After Hospital Discharge Following Acute Coronary Syndrome: Incidence, Types, Timing, and Predictors.

ABSTRACT: Background The incidence and predictors of bleeding after acute coronary syndrome are unclear within the real-world setting. Our objective was to determine the incidence, types, timing, and predictors of bleeding complications following hospital discharge after acute coronary syndrome. Methods and Results We used the Clinical Practice Research Datalink, with linkage to Hospital Episode Statistics, to determine the incidence, timing, and types of bleeding events within 12 months after hospital discharge for acute coronary syndrome. We assessed independent associations between postdischarge bleeding and baseline patient characteristics using a competing risk regression model, accounting for death as a competing event. Among 27 660 patients surviving to hospital discharge, 3620 (13%) experienced bleeding complications at a median time of 123 days (interquartile range, 45-223 days) after discharge. The incidence of bleeding was 162/1000 person-years (95% CI, 157-167/1000 person-years) within the first 12 months after hospital discharge. Bruising (949 bleeds [26%]) was the most common type of first bleeding event, followed by gastrointestinal bleed (705 bleeds [20%]), whereas intracranial bleed was relatively rare (81 bleeds [2%]). Significant predictors of postdischarge bleeding included history of bleeding complication, oral anticoagulant prescription, history of peripheral vascular disease, chronic obstructive pulmonary disease, and advanced age (>80 years). Predictors for postdischarge bleeding varied, depending on the anatomic site of the bleeding event. Conclusions Bleeding complications after hospital discharge for acute coronary syndrome are common. Patients who experience these bleeding events have distinct baseline characteristics, which vary by anatomic site of the bleed. These characteristics can inform risk-benefit considerations in deciding on favorable combination and duration of secondary antithrombotic therapy.

Project description:ObjectiveThe primary objective was to determine the incidence of bleeding events post acute coronary syndrome (ACS) following hospital discharge. The secondary objective was to determine the prognostic impact of bleeding on mortality, major adverse cardiovascular events (MACE), myocardial re-infarction and rehospitalisation in the postdischarge setting.DesignA narrative systematic review.Data sourceMedline, Embase, Amed and Central (Cochrane) were searched up to August 2018.Study selectionFor the primary objective, randomised controlled trials (RCT) and observational studies reporting on the incidence of bleeding post hospital discharge were included. For the secondary objective, RCTs and observational studies that compared patients with bleeding versus those without bleeding post hospital discharge vis-à-vis mortality, MACE, myocardial re-infarction and rehospitalisation were included.Results53 studies (36 observational studies and 17 RCTs) with a combined cohort of 714?458 participants for the primary objectives and 187?317 for the secondary objectives were included. Follow-up ranged from 1?month to just over 4 years. The incidence of bleeding within 12?months post hospital discharge ranged from 0.20% to 37.5% in observational studies and between 0.96% and 39.4% in RCTs. The majority of bleeds occurred in the initial 3 months after hospital discharge with bruising the most commonly reported event. Major bleeding increased the risk of mortality by nearly threefold in two studies. One study showed an increased risk of MACE (HR 3.00,95% CI 2.75 to 3.27; p<0.0001) with bleeding and another study showed a non-significant association with rehospitalisation (HR 1.20,95% CI 0.95 to 1.52; p=0.13).ConclusionBleeding complications following ACS management are common and continue to occur in the long term after hospital discharge. These bleeding complications may increase the risk of mortality and MACE, but greater evidence is needed to assess their long-term effects.Prospero registration numberCRD42017062378.

Project description:BACKGROUND:Prior studies of healthy populations have found religious practices to be associated with survival. However, no contemporary studies have examined whether religiosity influences survival among patients discharged from the hospital after an acute coronary syndrome (ACS). The present study examined the relationship between religious practices and 2-year all-cause mortality among hospital survivors of an ACS. METHODS:Patients hospitalized for an ACS were recruited from 6 medical centers in Massachusetts and Georgia between 2011 and 2013. Study participants self-reported three items assessing religiosity: strength/comfort from religion, petition prayers for health, and awareness of intercessory prayers by others. All cause-mortality within 2-years of hospital discharge was ascertained by review of medical records at participating study hospitals and from death certificates. Cox proportional hazards models were used to estimate the multivariable adjusted risk of 2-year all-cause mortality. RESULTS:Participants (n = 2,068) were on average 61 years old, 34% were women, and 81% were non-Hispanic White. Approximately 85% derived strength/comfort from religion, 61% prayed for their health, and 89% were aware of intercessions. Overall, 6% died within 2 years post-discharge. After adjusting for sociodemographic variables (age, sex, and race/ethnicity), petition prayers were associated with an increased risk of 2-year all-cause mortality (HR: 1.64; 95% CI: 1.01-2.66). With further adjustment for several clinical and psychosocial measures, this association was no longer statistically significant. Strength and comfort from religion and intercessory prayers were not significantly associated with mortality. CONCLUSIONS:Most ACS survivors acknowledge deriving strength and comfort from religion, praying for their health, and intercessions made by others for their health. Although the reported religious practices were not associated with post-discharge survival after multivariable adjustment, acknowledging that patients utilize their religious beliefs and practices as strategies to improve their health would ensure a more holistic approach to patient management and promote cultural competence in healthcare.

Project description:Aim: To assess platelet (PLT) function and bleeding risks in patients with acute coronary syndrome after tirofiban infusion. Methods: Patients diagnosed with acute coronary syndrome from May 2016 to February 2018 in the Department of Cardiac Intensive Care Unit, Zhongshan Hospital, were enrolled. They were symmetrically allocated into two groups: tirofiban treatment group or control group (without tirofiban treatment). Blood samples were collected 24 h postoperation for the evaluation of antiplatelet effect of tirofiban. We applied thromboelastography to detect on-treatment PLT reactivity and conducted laboratory tests to assess the risk of bleeding following tirofiban treatment. After discharge, telephone follow-up and outpatient interview were carried out. The primary clinical endpoint was major adverse cardiovascular events, including cardiovascular death, cardiovascular mortality, myocardial infarction, and revascularization for the targeted vascular lesion. Results: There were a total of 196 patients with acute coronary syndrome after screening with the inclusion criteria and the exclusion criteria. Ninety-eight patients were assigned to receive either tirofiban treatment or control treatment. Patients treated with tirofiban had more coronary lesions and stents implanted compared with the control group (P = 0.000). After tirofiban infusion, inhibition of platelet aggregation induced by thromboxane A2 and adenosine diphosphate was significantly higher compared to patients without tirofiban infusion (80.3% ± 19.6% vs. 72.6% ± 13.0%, P = 0.002; and 81.0% ± 19.8% vs. 75.4% ± 12.4%, P = 0.020, respectively). There was no significant difference in the reduction of hemoglobin (Hb), hematocrit (Hct), and PLT after administration of tirofiban, compared with baseline (P > 0.05). In addition, no significant differences were identified between the two groups with respect to Hb, Hct, and PLT after tirofiban infusion. However, C-reactive protein level, referred to as an inflammation marker, was significantly lowered after infusion tirofiban compared with the control group (11.9 ± 14.2 vs. 17.9 ± 21.2, P = 0.020). During the 1-year follow-up, the incidence rate of major adverse cardiovascular events remains indiscriminate between the two groups (P = 0.208). The assessments of cardiac biomarkers showed that tirofiban could decrease incidence of procedural myocardial infarction (odds ratio [OR] = 0.250, 95% confidence interval [CI] = 0.067-0.925, P = 0.027). At follow-up, the morbidity of left atrial dilation in tirofiban-treated patients, defined as enlargement of left atrial diameter >40mm, was lower compared to the control group (OR = 0.533, 95% CI = 0.301-0.945, P = 0.031). Conclusion: Tirofiban infusion could decrease PLT activation in patients with acute coronary syndrome without increasing the risk of bleeding. As a concomitant medication, tirofiban shows no benefit in reducing the occurrence of major adverse cardiovascular events.
