Abstract
Background The role of insurance on outcomes in non-ST-segment-elevation myocardial infarction (NSTEMI) patients is limited in the contemporary era. Methods From the National Inpatient Sample, adult NSTEMI admissions were identified [2000–2017]. Expected primary payer was classified into Medicare, Medicaid, private, uninsured and others. Outcomes included in-hospital mortality, overall and early coronary angiography, percutaneous coronary intervention (PCI), resource utilization and discharge disposition. Results Of the 7,290,565 NSTEMI admissions, Medicare, Medicaid, private, uninsured and other insurances were noted in 62.9%, 6.1%, 24.1%, 4.6% and 2.3%, respectively. Compared to others, those with Medicare insurance older (76 vs. 53–60 years), more likely to be female (48% vs. 25–44%), of white race, and with higher comorbidity (all P<0.001). Population from the Medicare cohort had higher in-hospital mortality (5.6%) compared to the others (1.9–3.4%), P<0.001. With Medicare as referent, in-hospital mortality was higher in other {adjusted odds ratio (aOR) 1.15 [95% confidence interval (CI), 1.11–1.19]; P<0.001}, and lower in Medicaid [aOR 0.95 (95% CI, 0.92–0.97); P<0.001], private [aOR 0.77 (95% CI, 0.75–0.78); P<0.001] and uninsured cohorts [aOR 0.97 (95% CI, 0.94–1.00); P=0.06] in a multivariable analysis. Coronary angiography (overall 52% vs. 65–74%; early 15% vs. 22–27%) and PCI (27% vs. 35–44%) were used lesser in the Medicare population. The Medicare population had longer lengths of stay, lowest hospitalization costs and fewer home discharges. Conclusions Compared to other types of primary payers, NSTEMI admissions with Medicare insurance had lower use of coronary angiography and PCI, and higher in-hospital mortality.

Abstract
OBJECTIVE To determine whether disparities in access to invasive cardiac procedures still exist for Medicaid patients, given how old earlier studies are and given changes in the interim in appropriateness guidelines. PATIENTS AND METHODS A total of 5,022 Medicaid and private insurance patients in New York from January 1, 2008 through December 31, 2009 under age 65 with ST-elevation myocardial infarction (STEMI) were compared with regard to their access to percutaneous coronary interventions (PCI) before and after controlling for numerous patient characteristics and other important factors. RESULTS Medicaid patients were significantly less likely to be admitted initially to a hospital certified to perform PCI (90.4% vs. 94.3%, P < 0.001). Also, Medicaid patients were found to be significantly less likely to undergo PCI than other patients (adjusted odds ratio [AOR] = 0.81, 95% CI 0.66, 0.98, P = 0.03). When the probability of each hospital performing PCI for STEMI patients was controlled for, Medicaid patients were still less likely to undergo PCI after controlling for other risk factors (AOR = 0.80, 95% CI 0.65, 0.99, P = 0.04). CONCLUSIONS Medicaid STEMI patients are significantly less likely to undergo PCI within the same day of admission as private pay patients even after adjusting for patient characteristics related to receiving PCI, and the strength of this relationship is not diminished when controlling for whether the admitting hospital has approval to perform PCI or controlling for the tendency of the admitting hospital to treat STEMI with PCI.

Abstract
Previous studies have documented disparities in both access to invasive cardiovascular procedures and outcomes in patients with Medicaid, Medicare, or no insurance. Outcomes by insurance have yet not been examined in a percutaneous coronary intervention (PCI) population. Data from patients undergoing PCI from June 2000 to June 2009 were retrospectively analyzed. Insurance was categorized as private, Medicare, Medicaid, and uninsured, according to the primary insurance at discharge. The outcome variable of interest was major adverse cardiac events (a composite of death, Q-wave myocardial infarction, and target vessel revascularization) at 1 year. Multivariable Cox regression analysis was stratified according to age <65 and ≥65 years. Of the 13,573 patients who had undergone PCI, 6,653 (49.0%) had private insurance, 6,150 (45.3%) had Medicare, 486 (3.6%) had Medicaid, and 284 (2.1%) were uninsured. Of the patients <65 years old, Medicaid (hazard ratio [HR] 1.59, 95% confidence interval [CI] 1.04 to 2.43), Medicare (HR 2.18, 95% CI 1.58 to 2.99), and no insurance (HR 2.41, 95% CI 1.36 to 4.27) were associated with greater rates of adjusted major adverse cardiac events at 1 year compared with private insurance. Of the patients ≥65 years old, only Medicaid (HR 3.07, 95% CI 1.09 to 8.61) was associated with a greater rate of adjusted major adverse cardiac events at 1 year. In conclusion, patients with government-sponsored insurance and no insurance have worse cardiovascular outcomes than patients with private insurance after PCI at 1 year. This implies that the provision of health insurance alone might not have a dramatic effect on cardiovascular outcomes after PCI.

Abstract
BACKGROUND This study addresses the impact of availability of on-site catheterization laboratories on the 1-year survival of patients with post-acute myocardial infarction ischemia (P-AMI-I), a high-risk subgroup of AMI patients. METHODS A prospective 5 month national survey was conducted in 1996 in all operating intensive care units (ICCUs) in Israel (N=26) and included 2377 patients. Four hundred and three (17%) had P-AMI-I, 317 of them were admitted to 18 ICCUs with on-site catheterization laboratories (CATH+) and 86 patients to 8 ICCUs without such facilities (CATH-). A retrospective analysis was performed comparing the in-hospital course and 7 day, 1 month and 1 year mortality data of CATH+ vs. CATH- patients. RESULTS Patient characteristics in both groups were similar with regard to age, gender AMI location, risk factors, hemodynamic parameters on admission and rate of thrombolytic therapy. Of patients in CATH+, 79% were catheterized before hospital discharge vs. 42% in CATH- (P<0.0001), 45 vs. 15% had PTCA (P<0.0001) and 19 vs. 9% had CABG (P<0.05). At 30 days, patients in CATH+ still had significantly more revascularization procedures (71 vs. 48%, P<0.001). Patients hospitalized in ICCUs with CATH+ and CATH- facilities had similar cardiac mortality rates at 7 days (2.0 vs. 2.3%), 30 days (5.7 vs. 4.7%) and at 1 year (7.6 vs. 7.0%). CONCLUSIONS Despite a more invasive strategy used during the index hospitalization of patients with P-AMI-I hospitalized in CATH+ ICCUs, their survival was similar to CATH- patients at 7 days, 30 days and at 1 year follow-up.

Abstract
An abundance of evidence is available from large, randomized clinical trials supporting the efficacy of therapies for the management of patients with acute coronary syndromes. For ST-segment elevation myocardial infarction (MI), a variety of databases can be used to assess how these therapies, both pharmacologic and invasive, are being integrated into real practice. Little information is available, however, with regard to how newer treatments are actually being implemented for patients with unstable angina and non-ST-segment elevation MI. There are several important issues to consider in evaluating current treatment practices for acute coronary syndromes, including limitations of clinical trial databases, a trend toward progressive shortening of length of hospital stay, and variations in the availability of resources among treatment centers. In response to the need for a broader database that would address the global impact of clinical management practices in acute coronary syndromes, the Global Registry of Acute Coronary Events (GRACE) Registry has been established. The GRACE Registry will initially collect data on patient care from a variety of treatment centers in 14 countries, the plan being to eventually enroll 10,000 patients per year. This international observational database will obtain information on the complete spectrum of acute coronary syndromes, with the specific goals of describing diagnostic and treatment strategies, determining hospital outcomes, improving quality of care, and developing hypotheses for future clinical research.
