Item Early coronary angiography and survival after out-of-hospital cardiac arrest: a systematic review and meta-analysis(BMJ Publishing Group, 2018-10-19) Khera, Rohan; CarlLee, Sheena; Blevins, Amy E.; Schweizer, Marin; Girotra, Saket; Ruth Lilly Medical Library, School of MedicineBackground: Although acute myocardial infarction is a common cause of out-of-hospital cardiac arrest (OHCA), the role of early coronary angiography in OHCA remains uncertain. We conducted a meta-analysis of observational studies to determine the association of early coronary angiography with survival in OHCA. Methods: We searched multiple electronic databases for published studies on early coronary angiography in OHCA between 1 January 1990 and 18 January 2017. Studies were included if (1) restricted to only OHCA, (2) included an exposure group that underwent early coronary angiography within 1 day of arrest onset and a concurrent control group that did not undergo early coronary angiography, and (3) reported survival outcomes. We used a random-effects model to obtain pooled OR. I2 statistics and Cochran's Q test were used to determine between-study heterogeneity. Results: A total of 17 studies with 14 972 patients were included, of whom 6424 (44%) received early coronary angiography. Early coronary angiography was associated with higher odds of survival (pooled OR 2.54 (95% CI 1.94 to 3.33)) and survival with favourable neurological outcome (pooled OR 2.37 (95% CI 1.71 to 3.28)). However, there was substantial heterogeneity in our pooled estimate (I2=88% and p value for Cochran's test <0.0001 for both outcomes). The large heterogeneity in pooled estimates was reduced after including adjusted estimates when available, and was explained by differences in methodological rigour and characteristics of included studies. Conclusion: Among patients resuscitated from OHCA, early coronary angiography is associated with increased survival to discharge and favourable neurological outcome.Item Racial and Ethnic Differences in Bystander CPR for Witnessed Cardiac Arrest(Massachusetts Medical Society, 2022) Garcia, R. Angel; Spertus, John A.; Girotra, Saket; Nallamothu, Brahmajee K.; Kennedy, Kevin F.; McNally, Bryan F.; Breathett, Khadijah; Del Rios, Marina; Sasson, Comilla; Chan, Paul S.; Medicine, School of MedicineBackground: Differences in the incidence of cardiopulmonary resuscitation (CPR) provided by bystanders contribute to survival disparities among persons with out-of-hospital cardiac arrest. It is critical to understand whether the incidence of bystander CPR in witnessed out-of-hospital cardiac arrests at home and in public settings differs according to the race or ethnic group of the person with cardiac arrest in order to inform interventions. Methods: Within a large U.S. registry, we identified 110,054 witnessed out-of-hospital cardiac arrests during the period from 2013 through 2019. We used a hierarchical logistic regression model to analyze the incidence of bystander CPR in Black or Hispanic persons as compared with White persons with witnessed cardiac arrests at home and in public locations. We analyzed the overall incidence as well as the incidence according to neighborhood racial or ethnic makeup and income strata. Neighborhoods were classified as predominantly White (>80% of residents), majority Black or Hispanic (>50% of residents), or integrated, and as high income (an annual median household income of >$80,000), middle income ($40,000-$80,000), or low income (<$40,000). Results: Overall, 35,469 of the witnessed out-of-hospital cardiac arrests (32.2%) occurred in Black or Hispanic persons. Black and Hispanic persons were less likely to receive bystander CPR at home (38.5%) than White persons (47.4%) (adjusted odds ratio, 0.74; 95% confidence interval [CI], 0.72 to 0.76) and less likely to receive bystander CPR in public locations than White persons (45.6% vs. 60.0%) (adjusted odds ratio, 0.63; 95% CI, 0.60 to 0.66). The incidence of bystander CPR among Black and Hispanic persons was less than that among White persons not only in predominantly White neighborhoods at home (adjusted odds ratio, 0.82; 95% CI, 0.74 to 0.90) and in public locations (adjusted odds ratio, 0.68; 95% CI, 0.60 to 0.75) but also in majority Black or Hispanic neighborhoods at home (adjusted odds ratio, 0.79; 95% CI, 0.75 to 0.83) and in public locations (adjusted odds ratio, 0.63; 95% CI, 0.59 to 0.68) and in integrated neighborhoods at home (adjusted odds ratio, 0.78; 95% CI, 0.74 to 0.81) and in public locations (adjusted odds ratio, 0.73; 95% CI, 0.68 to 0.77). Similarly, across all neighborhood income strata, the frequency of bystander CPR at home and in public locations was lower among Black and Hispanic persons with out-of-hospital cardiac arrest than among White persons. Conclusions: In witnessed out-of-hospital cardiac arrest, Black and Hispanic persons were less likely than White persons to receive potentially lifesaving bystander CPR at home and in public locations, regardless of the racial or ethnic makeup or income level of the neighborhood where the cardiac arrest occurred.Item Variation in Hospital-use and Outcomes Associated with Pulmonary Artery Catheterization in Heart Failure in the United States(American Heart Association, 2016-11) Khera, Rohan; Pandey, Ambarish; Kumar, Nilay; Singh, Rajeev; Bano, Shah; Golwala, Harsh; Kumbhani, Dharam J.; Girotra, Saket; Fonarow, Gregg C.; Medicine, School of MedicineBackground There has been an increase in the use of pulmonary artery (PA) catheters in heart failure (HF) in the United States in recent years. However, patterns of hospital-use and trends in patient outcomes are not known. Methods and Results In the National Inpatient Sample 2001–2012, using ICD-9 codes we identified 11,888,525 adult (≥18 years) HF hospitalizations nationally, of which an estimated 75,209 (SE 0.6%) received a PA catheter. In 2001, the number of hospitals with ≥1 PA catheterization was 1753, decreasing to 1183 in 2011. The mean PA catheter use per hospital trended from 4.9/year in 2001 (limits 1–133) to 3.8/year in 2007 (limits 1–46), but increased to 5.5/year in 2011 (limits 1–70). During 2001–2006, PA catheterization declined across hospitals; however, in 2007–2012 there has been a disproportionate increase at hospitals with large bedsize, teaching programs, and advanced HF capabilities. The overall in-hospital mortality with PA catheter use was higher than without PA catheter use (13.1% vs. 3.4%, P<0.0001), however, in propensity-matched analysis, differences in mortality between these groups have attenuated over time – risk-adjusted odds ratio for mortality for PA-catheterization, 1.66 (95% CI 1.60–1.74) in 2001–2003 down to 1.04 (95% CI 0.97– 1.12) in 2010–2012. Conclusions There is substantial hospital-level variability in PA catheterization in HF along with increasing volume at fewer hospitals overrepresented by large, academic hospitals with advanced HF capabilities. This is accompanied by a decline in excess mortality associated with PA catheterization.
