Guidelines for cardiac catheterization in patients with non-specific chest pain (NSCP) provide significant room for provider discretion, which has resulted in variability in the utilization of invasive coronary angiograms (CAs) and a high rate of normal angiograms. The overutilization of CAs in patients with NSCP and discharged without a diagnosis of coronary artery disease is an important issue in medical care quality. As a result, we sought to identify patient demographic, socioeconomic, and geographic factors that influenced the performance of a CA in patients with NSCP who were discharged without a diagnosis of coronary artery disease. We intended to establish reference data points for gauging the success of new initiatives for the evaluation of this patient population. In this 20-year retrospective cohort study (1994-2014), we examined 107 796 patients with NSCP from the Myocardial Infarction Data Acquisition System, a large statewide validated database that contains discharge data for all patients with cardiovascular disease admitted to every non-federal hospital in NJ. Patients were partitioned into two groups: those offered a CA (CA group; n = 12 541) and those that were not (No-CA group; n = 95 255). Geographic, demographic, and socioeconomic variables were compared between the two groups using multivariable logistic regression, which determined the predictive value of each categorical variable on the odds of receiving a CA. Whites were more likely than Blacks and other racial counterparts (19.7% vs. 5.6% and 16.5%, respectively; P < .001) to receive a CA. Geographically, patients who received a CA were more likely admitted to a large hospital compared to small- or medium-sized ones (12.5% vs. 8.9% and 9.7%, respectively; P < .05), a primary teaching institution rather than a teaching affiliate or community center (16.1 % vs. 14.3% and 9.1%, respectively; P < .001), and at a non-rural facility compared to a rural one (12.1% vs. 6.5%; P < .001). Lastly from a socioeconomic standpoint, patients with commercial insurance more often received a CA compared to those having Medicare or Medicaid/self-pay (13.7% vs. 9.5% and 6.0%, respectively; P < .001). The utilization of CA in patients with NSCP discharged without a diagnosis of coronary artery disease in NJ during the study period may be explained by differences in geographic, demographic, and socioeconomic factors. Patients with NSCP should be well scrutinized for CA eligibility, and reliable strategies are needed to reduce discretionary medical decisions and improve quality of care.

Background In 1998, President Clinton launched a federal initiative to eliminate racial and ethnic health disparities. The impact on the outcomes of ST-segment-elevation myocardial infarction has not been well studied. Methods and Results ST-segment-elevation myocardial infarction outcomes from 1994 to 2015 were studied in 7942 Black, 27 665 Hispanic, and 88 727 White patients with first admission of ST-segment-elevation myocardial infarction using the Myocardial Infarction Data Acquisition System. Logistic regressions were used to assess mortality adjusting for demographics, comorbidities, and interventional procedures. There was an overall rise from 1994 to 2015 in the use of percutaneous coronary interventions in all 3 groups. Before 1998, White patients received more percutaneous coronary interventions compared with Black and Hispanic patients (P<0.05). After 1998, the disparity in use of percutaneous coronary interventions in Black and Hispanic patients was greatly reduced compared with White patients, and the difference reversed in favor of Hispanic patients after 2005 (P<0.05). There was an overall downward trend of in-hospital mortality without evidence of disparity among Black, Hispanic, and White patients. A linear regression model was used with a change point in 1998. Before 1998, the slope of 1-year all-cause and cardiovascular mortality was not statistically significant. After 1998, the mortality showed negative slopes for all 3 groups, however, with lower overall crude mortality for Hispanic patients compared with Black and White patients (P<0.0001). Conclusions The initiative launched in 1998 may have contributed to a reduction in percutaneous coronary intervention usage disparity in patients with ST-segment-elevation myocardial infarction. Short- and long-term mortality decreased in all 3 groups, but more in the Hispanic population.

Introduction: There are more than 250,000 publications on COVID-19. However, there is incomplete information on the effects of pharmacologic therapy in hospitalized patients. Hypothesis: We hypothesize that use of statin therapy will decrease all-cause mortality in patients hospitalized for COVID-19. Methods: A dataset of 1,064 patients with first admission for COVID-19 was used in this study. Predictive models using logistic regression, support-vector machines, and neural networks were used to predict all-cause in-hospital death. Results: In-hospital case fatality of patients admitted with COVID-19 was 17.5% and was higher in the first week after admission, among older individuals, those with higher body weight, and those with longer length of stay. The use of statins was associated with lower in-hospital mortality after adjustment for other medications and the factors mentioned above. The beneficial effect of statins may not be due to their effects on lipids but is probably due to their pleiotropic antioxidant effects. Using logistic regression, the duration of therapy was positively related to the beneficial effect of statins (p=0.0002). Conclusions: In conclusion, the in-hospital case fatality of COVID-19 patients was lower in patients receiving statins after adjustment for demographics, other medications, body weight, and length of stay (Figure).

BACKGROUND:Constrictive pericarditis is a rare complication of open heart surgery (OHS), but little is known regarding the etiologic determinants, and prognostic factors. The purpose of this study was to investigate clinical predictors and long term prognosis of post-operative constrictive pericarditis (CP). METHODS:Using the Myocardial Infarction Data Acquisition System database, we analyzed records of 142,837 patients who were admitted for OHS in New Jersey hospitals between 1995 and 2015. Ninety-one patients were hospitalized with CP 30 days or longer after discharge from OHS. Differences in proportions were analyzed using Chi square tests. Controls were matched to cases for demographics, surgical procedure type, history of OHS, and propensity score. Cox proportional hazard models were used to evaluate the risk of all-cause death. Log-rank tests and Cox models were used to assess differences in the Kaplan-Meier survival curves with and without adjustments for comorbidities. RESULTS:Patients with CP were more likely to have history of valve disease (VD, p < 0.001), atrial fibrillation (AF, p = 0.024) renal disease (CKD, p = 0.028), hemodialysis (HD, p = 0.008), previous OHS (p < 0.001). Patients with CP compared to matched controls had a higher 7-year mortality (p < 0.001). This difference became statistically significant at 1-year after surgery. CONCLUSION:CP is a rare complication of OHS that occurs more frequently in patients with VD, AF, CKD, HD, multiple OHS, and it is associated with an unfavorable long-term prognosis. Given the large number of OHS performed every year, the results highlight the need for clinicians to recognize and properly manage this complication of OHS.

Abstract This post hoc analysis of the Systolic Blood Pressure Intervention Trial (SPRINT) examined the performance of chlorthalidone (C) versus amlodipine (A) monotherapies. ANOVA was used to analyze the differences in systolic blood pressure (SBP) response between C and A. Logistic regression was used to examine monotherapy failure (adding a second antihypertensive agent or switching to a different antihypertensive agent) rates. Four hundred ninety‐one participants were treated with C monotherapy (n = 210, mean dose = 22 mg/day) or A monotherapy (n = 281, mean dose = 7 mg/day). There was a significant difference in mean SBP reduction between the C and A monotherapies at the third visit (higher reduction with A, adjusted p = .018). Unadjusted analysis showed a higher failure with C in the standard treatment group. Although the average SBP at failure was higher and above the 140 mm Hg cutoff that indicated monotherapy failure with A (142.60) compared with C (138.40), more participants on C failed despite having SBP below the 140 cutoff. This was probably due to decisions made by the investigative teams to change the antihypertensive regimen, because, in their opinion, the clinical picture required it. After adjusting for baseline characteristics, C had higher failure than A only in the standard treatment group (1.64 odds ratio [OR], 95% CI 1.06–2.56, p = .028). A sub‐analysis including participants who had never used antihypertensive treatment before randomization had similar results (2.57 OR, 95% CI 1.34–5.02, p = .004). Overall, in SPRINT chlorthalidone was associated with higher monotherapy failure than amlodipine in the standard treatment group because of decisions of the investigative teams.

We investigated the incidence and characteristics of 14,996 patients with aortic stenosis (AS) who were hospitalized in New Jersey between the years 1995 to 2015. The average age was 72, the majority were Caucasian males and common co-morbidities were hypertension, coronary artery disease and hypercholesterolemia. Hospital admission for AS declined between 1995 to 2007, to 10/100,000 patients, and increased to 15/100,000 patients in 2015 (p for trend < 0.001). During the study period, the percentage of patients who received aortic valve replacement (AVR) increased (p < 0.001). All-cause and cardiovascular mortality were higher among patients who did not undergo AVR at 1-year (HR 1.98 CI 1.75 to 2.23, p < 0.001 and HR 1.82 CI 1.57 to 2.11, p < 0.001, respectively) and 3-years (HR 2.16 CI 1.96 to 2.38, p < 0.001 and HR 2.16 CI 1.90 to 2.45, p < 0.001, respectively). The probability for readmission for AS was higher in patients who did not receive AVR compared to patients who had AVR at 1 year (HR 92.95 CI 57.85 to 149.35, p <0.001) and 3 years (HR 70.36 CI 47.18 to 104.95, p <0.001). These data imply that earlier diagnosis of AS and AVR when indicated will improve outcomes. (C) 2021 Elsevier Inc. All rights reserved.

Acute mitral valve insufficiency (AMVI) is a catastrophic complication of ST-elevation myocardial infarction (STEMI). We hypothesize improvements in medical and surgical treatment have reduced hospital and 1-year mortality. Using the New Jersey MIDAS database, we identified 831 patients admitted

Introduction: Acute myocardial infarction (AMI) accounts for the majority of patients with cardiogenic shock (CS). The high case fatality justifies the need for an optimal hospital care system that is available 24 hours, 7 days a week. It is unclear whether the “weekend effect” has an impact on the outcome of CS associated with AMI. Hypothesis: Weekend CS-AMI admissions have a higher in-hospital case fatality than weekday admissions. Methods: A total of 22,632 patients with ST segment elevation AMI complicated with CS between the years 1986 to 2015 were identified in the Myocardial Infarction Data Acquisition System, a statewide database of all admissions to non-federal hospitals in NJ. Trend analysis was performed using a logistic regression model with admission year as a continuous variable. Case fatality rates between weekend vs weekday admissions were compared using the Cochran–Mantel–Haenszel test, stratifying by admission year. Results: From 1986 to 2015 there was a steady decline in the rates of in-hospital case fatality of AMI complicated with CS, from 79% to 33% (p< 0.001). The overall CS death rate for admissions on weekends was 61% and for weekdays 59% (Common-Odds Ratio = 1.10 (95% CI (1.02-1.17) p= 0.006) (figure). The use of mechanical circulatory support (MCS) was lower on weekends (p<0.001) and was associated with a higher case fatality rate 48 hours from admission (p<0.001). Conclusion: Deaths related to CS complicating AMI have steadily declined and this applies for both, patients admitted on weekends and weekdays. There was a higher hospital death rate in patients admitted over weekends compared to weekdays. The underutilization of MCS devices during weekends likely contributes to the difference in case fatality between weekends and weekdays.

We examined the association of orthostatic hypertension with all-cause mortality in the active treatment and placebo randomized groups of the Systolic Hypertension in the Elderly Program (SHEP). SHEP was a multicenter, randomized, double-blind, placebo-controlled clinical trial of the effect of chlorthalidone-based antihypertensive treatment on the rate of occurrence of stroke among older persons with isolated systolic hypertension (ISH). Men and women aged 60 years and above with ISH defined by a systolic blood pressure (SBP) of 160 mm Hg or higher and diastolic blood pressure lower than 90 mm Hg were randomized to chlorthalidone-based stepped care therapy or matching placebo. Among 4736 SHEP participants, 4073 had a normal orthostatic response, 203 had orthostatic hypertension, and 438 had orthostatic hypotension. Compared with normal response, orthostatic hypertension was associated with higher all-cause mortality at 4.5 and 17 years in analyses adjusted for age, gender, treatment, SBP, and pulse pressure (PP, HR 1.87, 95% CI 1.30–2.69, p = 0.0007; HR 1.40, 95% CI 1.17–1.68, p = 0.0003, respectively). These associations remained significant after additional adjustment for risk factors and comorbidities (HR 1.43, 95% CI 0.99–0.08, p = 0.0566 at 4.5 years, and HR 1.27, 95% CI 1.06–1.53, p = 0.0096 at 17 years). The increased risk of all-cause mortality associated with orthostatic hypertension was observed in both the active and placebo groups without significant interaction between randomization group and the effect on mortality. Orthostatic hypertension is associated with future mortality risk, is easily detected, and can be used in refining cardiovascular risk assessment.

Background: Operative management of aortic stenosis (AS) evolved over the last 20 years, and it is unknown how those advances changed outcomes and management of patients with AS. We aimed to define...

We postulate that the trends for infective endocarditis (IE) are different for patients admitted for this condition compared with those admitted for a different reason with IE as a secondary diagnosis. Using the Myocardial Infarction Data Acquisition System (MIDAS) database, we analyzed 21,443 records of patients hospitalized with diagnosis of IE from 1994 to 2015. There were 9,191 patients hospitalized with IE as the primary diagnosis, and 12,252 patients with IE as a secondary diagnosis. Piecewise linear models were used to detect changes in trends. A bootstrap method was used to assess the statistical significance of the slopes and break point of each model. Differences in co-morbidities and microbiological patterns were analyzed. Trend analysis showed a significant decrease in IE as the primary diagnosis starting in the year 2004 (p<0.01). Hospitalizations with IE as a secondary diagnosis showed a linear increase in incidence (p<0.001), without any change points. In primary diagnosis IE, the proportion of streptococci as a causative microorganism was higher compared with staphylococci (p<0.001). On the contrary, in secondary diagnosis IE, the proportion of staphylococci was higher than streptococci (p<0.001). The proportion of gram-negative and other organism IE was similar in both groups. In conclusion, this study showed 2 divergent temporal trends in hospitalizations for IE as a primary or secondary diagnosis starting in 2004. The profile of the microorganisms reveals a steady higher proportion of staphylococcal infection in secondary diagnosis IE compared with streptococcal infection. Different strategies are needed for the prevention of IE. (C) 2019 Elsevier Inc. All rights reserved.
