RESUMEN
Objective: The proportion of ST-segment elevation myocardial infarction (STEMI) patients without standard modifiable risk factors (SMuRFs: hypertension, diabetes, hypercholesterolemia and smoking) has increased over time. The absence of SMuRFs is known to be associated with worse outcomes, but its association with age and sex is uncertain. We sought to evaluate the association between age and sex with the outcomes of post-STEMI patients without SMuRFs among patients without preexisting coronary artery disease. Methods: Patients who underwent primary PCI for STEMI were identified from the Nationwide Readmission Database of the United States. Clinical characteristics, in-hospital, and 30-day outcomes in patients with or without SMuRFs were compared in men versus women and stratified into five age groups. Results: Between January 2010 and November 2014, of 474,234 patients who underwent primary PCI for STEMI, 52,242 (11.0%) patients did not have SMuRFs. Patients without SMuRFs had higher in-hospital mortality rates than those with SMuRFs. Among those without SMuRFs, the in-hospital mortality rate was significantly higher in women than men (10.6% vs 7.3%, p<0.001), particularly in older age groups. The absence of SMuRFs was associated with higher 30-day readmission-related mortality rates (0.5% vs 0.3% with SMuRFs, p<0.001). Among patients without SMuRFs, women had a higher 30-day readmission-related mortality rates than men (0.6% vs 0.4%, p<0.001). After multivariable adjustment, the increased rates of in-hospital (odds ratio 1.89 (95% CI 1.72 to 2.07) and 30-day readmission-related mortality (hazard ratio 1.30 (95% CI 1.01 to 1.67)) in patients without SMuRFs remained significant. Conclusions: STEMI patients without SMuRFs have a significantly higher risk of in-hospital and 30-day mortality than those with SMuRFs. Women and older patients without SMuRFs experienced significantly higher in-hospital and 30-day readmission-related mortality.
RESUMEN
Background There are limited data on the sex-based differences in the outcome of readmission after cardiac arrest. Methods and Results Using the Nationwide Readmissions Database, we analyzed patients hospitalized with cardiac arrest between 2010 and 2015. Based on International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes, we identified comorbidities, therapeutic interventions, and outcomes. Multivariable logistic regression was performed to assess the independent association between sex and outcomes. Of 835 894 patients, 44.4% (n=371 455) were women, of whom 80.7% presented with pulseless electrical activity (PEA)/asystole. Women primarily presented with PEA/asystole (80.7% versus 72.4%) and had a greater comorbidity burden than men, as assessed using the Elixhauser Comorbidity Score. Thirty-day readmission rates were higher in women than men in both PEA/asystole (20.8% versus 19.6%) and ventricular tachycardia/ventricular fibrillation arrests (19.4% versus 17.1%). Among ventricular tachycardia/ventricular fibrillation arrest survivors, women were more likely than men to be readmitted because of noncardiac causes, predominantly infectious, respiratory, and gastrointestinal illnesses. Among PEA/asystole survivors, women were at higher risk for all-cause (adjusted odds ratio [aOR], 1.07; [95% CI, 1.03-1.11]), cardiac-cause (aOR, 1.15; [95% CI, 1.06-1.25]), and noncardiac-cause (aOR, 1.13; [95% CI, 1.04-1.22]) readmission. During the index hospitalization, women were less likely than men to receive therapeutic procedures, including coronary angiography and targeted therapeutic management. While the crude case fatality rate was higher in women, in both ventricular tachycardia/ventricular fibrillation (51.8% versus 47.4%) and PEA/asystole (69.3% versus 68.5%) arrests, sex was not independently associated with increased crude case fatality after adjusting for differences in baseline characteristics. Conclusions Women are at increased risk of readmission following cardiac arrest, independent of comorbidities and therapeutic interventions.

Background: Severe mitral regurgitation is a progressive disease associated with high morbidity and mortality, and frequent readmissions for heart failure. Surgical mitral valve repair or replacement has been the gold-standard treatment; however, advances in transcatheter edge-to-edge repair (TEER) have provided alternatives for high-risk surgical patients. There are no data on racial disparities in access to high-volume TEER centers. Methods: Data on TEER hospitalizations from New York, New Jersey, Maryland, North Carolina, Washington, Colorado, Arizona, and Florida were analyzed using the State Inpatient Databases for 2016. The baseline characteristics of patients who underwent TEER at high- (≥25 procedures per year) and low-volume centers were identified. The association between race and the likelihood of undergoing TEER at high-volume centers was assessed. The secondary outcomes were mortality and the frequency of home discharges. Results: Of 1567 patients included in the analysis, 1129 underwent TEER at high-volume centers. Patients treated at high-volume centers had a higher prevalence of chronic kidney disease and congestive heart failure. Black and Hispanic patients were 59% (adjusted odds ratio [OR], 0.41; P < .001) and 51% (adjusted OR, 0.49; P < .001) less likely to undergo TEER at high-volume centers, respectively, compared with White patients. Hispanic patients were 3 times more likely to die during index admission than White patients (adjusted OR, 3.32; P = .027). There was geographic clustering of TEER centers, and a higher ratio of White patients to minority patients in zip codes with high-volume TEER centers. Conclusions: Racial minorities patients, particularly Black and Hispanic patients, are less likely to undergo TEER at high-volume centers. Hispanic patients experience higher rates of in-hospital mortality after TEER than White patients.
RESUMEN
BACKGROUND: Cardiovascular disease is the leading cause of death for women in the United States. Revascularization is considered the standard of care for treatment of ST-segment elevation myocardial infarction (STEMI) and is known to reduce readmission. However there is a paucity of data that examines the sex-dependent impact of revascularization on readmission. We aimed to investigate sex differences in revascularization rates, 30-day readmission rates, and primary cause of readmissions following STEMIs. METHODS: STEMI hospitalizations were selected in the Nationwide Readmissions Database from 2010 to 2014. Revascularization rates, 30-day readmission rates, and primary cause of readmission were examined. Interaction between sex and revascularization was assessed. Multivariable regression analysis was performed to identify predictors of 30-day readmission and revascularization for both sexes. RESULTS: 219,944 women and 489,605 men were admitted with STEMIs. Women were more likely to be older, and have more comorbidities. Women were less likely to undergo revascularization by percutaneous coronary intervention (adjusted odds ratio [OR]: 0.68; 95% confidence interval [CI]: 0.66-0.70) or coronary artery bypass graft surgery (adjusted OR 0.40; CI 0.39-0.44). Women had higher 30-day readmission rates (15.7% vs. 10.8%, p < 0.001; OR 1.20, CI 1.17-1.23), and revascularization in women was not associated with a decreased likelihood of 30-day readmission. The primary cardiac cause of readmission in women was heart failure. CONCLUSION: Compared to men, women with STEMIs had lower rates of revascularization and higher rates of 30-day readmission. When revascularized, women were still more likely to be readmitted as compared to non-revascularized women.

PURPOSE/OBJECTIVE(S): The presence of coronary artery calcium (CAC>0) is associated with increased cardiac-related mortality and is a common indication to initiate statin therapy to prevent future long-term cardiac-related adverse events. CAC is also well visualized on noncontrast chest computed tomography simulation (CT sim) scans used for breast radiation planning. We hypothesize that by screening for incidental CAC on CT sims, radiation oncologists could help identify patients who may benefit from additional preventive medical interventions with their primary care physician or cardiologist. METHODS: A retrospective analysis of 126 consecutive patients with breast cancer treated with external beam radiation therapy at a single institution was performed. Noncontrast CT sim scans were reviewed for the presence of CAC and the 10-year risk of atherosclerotic cardiovascular disease (ASCVD) was calculated to identify patients who may benefit from initiating statin therapy. Patients with CAC>0 and/or ASCVD risk >20% were identified as those who may benefit from statin therapy. RESULTS: Out of 72 patients with CAC>0, only 12(16%) had reported pre-existing coronary artery disease and 32(44%) were not already on recommended statin therapy. CAC>0 visualized on CT sim was able to identify 29 additional patients who would benefit from statin beyond what the ASCVD risk calculator could identify. CONCLUSION: Observation of incidental CAC on breast radiation-planning CT scans identified patients who could benefit from cardiac-related preventive strategies. By increasing attention, awareness, and reporting of incidental CAC visible on CT sims, radiation oncologists may fulfill a unique role to bridge a potential gap in cardiovascular preventive medicine.

OBJECTIVE: The American Society of Clinical Oncology (ASCO) 2017 guidelines on cardiac monitoring during cancer treatments identified patients receiving thoracic radiation (TRT) ≥30 Gy (heart in field) at increased risk for developing radiation-induced heart disease (RIHD). ASCO encouraged clinicians to actively screen and monitor for baseline modifiable cardiac risk factors and therapy-induced cardiotoxicity in this high-risk population. Coronary artery calcium (CAC) is an independent risk factor for adverse cardiac events that can be mitigated with preventative medical therapy. It is unclear whether radiation oncologists (ROs) are aware of ASCO guidelines or the implications of CAC observed on computed tomographic scans. We report on practice patterns, perceptions, and experiences of cardiac monitoring for patients receiving definitive TRT, excluding breast patients. MATERIALS AND METHODS: A 28-question survey was emailed to United States ROs 3 times from September 2018 to January 2019. RESULTS: There were 162 respondents from 42 states, 51% in academic practice. Most ROs (81%) were not aware of the ASCO guidelines. Only 24% agreed with the guidelines, only 27% believed symptomatic RIHD could manifest within 2 years of TRT, and 69% thought there was a lack of strong evidence for type and timing of cardiac monitoring tests. If CAC was evident on computed tomographic scans, 40% took no further action to inform the patient or referring doctor. CONCLUSIONS: This survey highlights a critical gap in knowledge about cardiac monitoring and potentially life-saving opportunities for preventive cardiac medical management. Future studies focusing on timing and detection of RIHD may elucidate the utility of cardiac monitoring for TRT patients.

In 2018, cardiovascular disease (CVD) was the leading cause of death among women, and current CVD prevention paradigms may not be sufficient in this group. In that context, it has recently been proposed that detection of calcification in breast arteries may help improve CVD risk screening and assessment in apparently healthy women. This review provides an overview of breast arterial anatomy; and the epidemiology, pathophysiology, and measurement of breast artery calcium (BAC); and discusses the features of the BAC-CVD link. The potential clinical applications that BAC may offer for CVD prevention in the context of current clinical practice guidelines and recommendations are also discussed. Finally, current gaps in evidence gaps are outlined, and future directions in the field are explored with a focus on the implementation of BAC mammography as a CVD risk-screening tool in routine clinical practice.

The newly released 2013 ACC/AHA Guidelines for Assessing Cardiovascular Risk makes progress compared with previous cardiovascular risk assessment algorithms. For example, the new focus on total atherosclerotic cardiovascular diseases (ASCVD) is now inclusive of stroke in addition to hard coronary events, and there are now separate equations to facilitate estimation of risk in non-Hispanic white and black individuals and separate equations for women. Physicians may now estimate lifetime risk in addition to 10-year risk. Despite this progress, the new risk equations do not appear to lead to significantly better discrimination than older models. Because the exact same risk factors are incorporated, using the new risk estimators may lead to inaccurate assessment of atherosclerotic cardiovascular risk in special groups such as younger individuals with unique ASCVD risk factors. In general, there appears to be an overestimation of risk when applied to modern populations with greater use of preventive therapy, although the magnitude of overestimation remains unclear. Because absolute risk estimates are directly used for treatment decisions in the new cholesterol guidelines, these issues could result in overuse of pharmacologic management. The guidelines could provide clearer direction on which individuals would benefit from additional testing, such as coronary calcium scores, for more personalized preventive therapies. We applaud the advances of these new guidelines, and we aim to critically appraise the applicability of the risk assessment tools so that future iterations of the estimators can be improved to more accurately assess risk in individual patients.
