RESUMEN
BACKGROUND AND AIMS: Persons with rheumatoid arthritis (RA) have an increased risk of obstetric-associated complications, as well as long-term cardiovascular (CV) risk. Hence, the aim was to evaluate the association of RA with acute CV complications during delivery admissions. METHODS: Data from the National Inpatient Sample (2004-2019) were queried utilizing ICD-9 or ICD-10 codes to identify delivery hospitalizations and a diagnosis of RA. RESULTS: A total of 12 789 722 delivery hospitalizations were identified, of which 0.1% were among persons with RA (n = 11 979). Individuals with RA, vs. those without, were older (median 31 vs. 28 years, P < .01) and had a higher prevalence of chronic hypertension, chronic diabetes, gestational diabetes mellitus, obesity, and dyslipidaemia (P < .01). After adjustment for age, race/ethnicity, comorbidities, insurance, and income, RA remained an independent risk factor for peripartum CV complications including preeclampsia [adjusted odds ratio (aOR) 1.37 (95% confidence interval 1.27-1.47)], peripartum cardiomyopathy [aOR 2.10 (1.11-3.99)], and arrhythmias [aOR 2.00 (1.68-2.38)] compared with no RA. Likewise, the risk of acute kidney injury and venous thromboembolism was higher with RA. An overall increasing trend of obesity, gestational diabetes mellitus, and acute CV complications was also observed among individuals with RA from 2004-2019. For resource utilization, length of stay and cost of hospitalization were higher for deliveries among persons with RA. CONCLUSIONS: Pregnant persons with RA had higher risk of preeclampsia, peripartum cardiomyopathy, arrhythmias, acute kidney injury, and venous thromboembolism during delivery hospitalizations. Furthermore, cardiometabolic risk factors among pregnant individuals with RA rose over this 15-year period.

OBJECTIVES: Aneurysmal subarachnoid hemorrhage (aSAH) accounts for 5% of strokes but results in significant morbidity and mortality. In addition to systemic inflammation, up to half of patients develop cardiac injury; however, the relationship between systemic inflammation and cardiac injury after aSAH is unknown. We investigated changes in leukocyte counts in relation to cardiac dysfunction MATERIALS AND METHODS: We reviewed the records of consecutive patients with SAH at our large academic medical referral center. The inclusion criteria were aSAH and available cardiac troponin I (cTnI) levels within 48 h of admission. The primary outcome was cardiac injury, defined as cTnI ≥0.04 ng/mL (lab reference range 0.01-0.03 ng/mL). We compared baseline characteristics, including serum leukocyte counts and performed univariable and multivariable logistic regression analysis to determine whether changes in leukocyte subpopulations predict cardiac injury. RESULTS: Of 288 SAH patients, 250 met inclusion criteria. Of these, 116 (46.4%) had elevated cTnI. In univariable analysis, total leukocyte count (p < 0.001), absolute neutrophil count (ANC, p < 0.001), and absolute monocyte count (p = 0.013), were associated with elevated cTnI. in multivariable analysis, total leukocyte count (OR=1.079, p = 0.037) and ANC (OR=1.081, p = 0.044) remained predictors of elevated cTnI. Adjusted ANC distinguishes between aSAH patients with normal and elevated TnI (area under the curve=0.766, p < 0.001) with specificity of 89.2%. CONCLUSIONS: Elevated total leukocytes and ANC are independently associated with cardiac injury in aSAH. Systemic inflammatory responses after aSAH may play a role in cardiac dysfunction, warranting additional studies to further characterize how cardiac inflammation after aSAH drives subsequent morbidity and mortality.

PURPOSE OF REVIEW: Heart centers for women (HCW) were developed due to the rising cardiovascular morbidity and mortality in women in the United States in the early 1990s. Our review encompasses the epidemiology, risk factors, diagnostic strategies, treatments, and the role of HCW in managing women with ischemic heart disease (IHD). RECENT FINDINGS: HCW use a multidisciplinary team to manage women with IHD. Due to the paucity of randomized controlled trials investigating various manifestations of IHD, some treatments are not evidence-based such as those for coronary microvascular dysfunction and spontaneous coronary artery dissection. Sex-specific risk factors have been identified and multimodality cardiac imaging is improving in diagnosing IHD in women. Treatments are being studied to help improve symptoms and outcomes in women with IHD. There has been progress in the care of women with IHD. HCW can be instrumental in treating women with IHD, doing research, and being a source of research study participants.

INTRODUCTION: Portable ECG devices are widely available yet there are limited data on their accuracy, physician and patient perceptions, and ease of use. The purpose of this study was to evaluate the accuracy of 4 single-lead portable ECG devices compared to a conventional 3-lead hospital cardiac monitor and to assess physician and patient perceptions of portable ECG devices. METHODS: Twenty consecutive hospitalized patients were provided 4 portable ECG devices for 30 second cardiac rhythm recording. ECG rhythm strips from the portable ECG devices were interpreted by a group of 5 physician reviewers. The reviewers then compared the portable ECG device rhythm strips to simultaneously recorded hospital cardiac monitor rhythm strips to determine physician preference. A cardiac electrophysiologist interpreted ECG rhythm strips from the hospital cardiac monitor as the "gold standard." Rhythm interpretations of the portable ECG devices and the hospital cardiac monitor were analyzed to evaluate clinical accuracy. Patient perceptions were evaluated by a 20-item questionnaire. RESULTS: There was less than 50% concordance of portable ECG device rhythm strips with the hospital cardiac monitor (when uninterpretable rhythm strips were included). Physicians usually preferred interpreting ECGs from hospital cardiac monitors compared to portable ECG devices. Manufacturer instructions were insufficient to allow patients to operate portable ECG devices in a limited time. Most patients felt comfortable using a portable ECG device if prescribed by a physician. CONCLUSION: Portable ECG devices may be a reasonable option for long-term rhythm surveillance in select patients. Widespread use of these devices cannot be endorsed unless improvements in their accuracy are properly addressed.

BACKGROUND: Left ventricular diastolic impairment and consequently elevated filling pressure may contribute to stasis leading to left atrial appendage thrombus (LAAT) in nonvalvular atrial fibrillation (AF). We investigated whether transthoracic echocardiographic parameters can predict LAAT independent of traditional clinical predictors. METHODS: We conducted a retrospective cohort study of 297 consecutive nonvalvular AF patients who underwent transthoracic echocardiogram followed by a transesophageal echocardiogram within one year. Multivariate logistic regression analysis models were used to determine factors independently associated with LAAT. RESULTS: Nineteen subjects (6.4%) were demonstrated to have LAAT by transesophageal echocardiography. These patients had higher mean CHADS2 scores [2.6 ± 1.2 vs. 1.9 ± 1.3, P = 0.009], higher E:e' ratios [16.6 ± 6.1 vs. 12.0 ± 5.4, P = 0.001], and lower mean e' velocities [6.5 ± 2.1 cm/sec vs. 9.1 ± 3.2 cm/sec, P = 0.001]. Both E:e' and e' velocity were associated with LAAT formation independent of the CHADS2 score, warfarin therapy, left ventricular ejection fraction (LVEF), and left atrial volume index (LAVI) [E:e' odds-ratio = 1.14 (95% confidence interval = 1.03 - 1.3), P = 0.009; e' velocity odds-ratio = 0.68 (95% confidence interval = 0.5 - 0.9), P = 0.007]. Similarly, diastolic function parameters were independently associated with spontaneous echo contrast. CONCLUSION: The diastolic function indices E:e' and e' velocity are independently associated with LAAT in nonvalvular AF patients and may help identify patients at risk for LAAT.

Nicotine is universally recognized as the primary addictive substance fuelling the continued use of tobacco products, which are responsible for over 8 million deaths annually. In recent years, the popularity of newer recreational nicotine products has surged drastically in many countries, raising health and safety concerns. For decades, the tobacco industry has promoted the myth that nicotine is as harmless as caffeine. Nonetheless, evidence shows that nicotine is far from innocuous, even on its own. In fact, numerous studies have demonstrated that nicotine can harm multiple organs, including the respiratory and cardiovascular systems. Tobacco and recreational nicotine products are commercialized in various types and forms, delivering varying levels of nicotine along with other toxic compounds. These products deliver nicotine in profiles that can initiate and perpetuate addiction, especially in young populations. Notably, some electronic nicotine delivery systems (ENDS) and heated tobacco products (HTP) can deliver concentrations of nicotine that are comparable to those of traditional cigarettes. Despite being regularly advertised as such, ENDS and HTP have demonstrated limited effectiveness as tobacco cessation aids in real-world settings. Furthermore, ENDS have also been associated with an increased risk of cardiovascular disease. In contrast, nicotine replacement therapies (NRT) are proven to be safe and effective medications for tobacco cessation. NRTs are designed to release nicotine in a slow and controlled manner, thereby minimizing the potential for abuse. Moreover, the long-term safety of NRTs has been extensively studied and documented. The vast majority of tobacco and nicotine products available in the market currently contain nicotine derived from tobacco leaves. However, advancements in the chemical synthesis of nicotine have introduced an economically viable alternative source. The tobacco industry has been exploiting synthetic nicotine to circumvent existing tobacco control laws and regulations. The emergence of newer tobacco and recreational nicotine products, along with synthetic nicotine, pose a tangible threat to established tobacco control policies. Nicotine regulations need to be responsive to address these evolving challenges. As such, governments should regulate all tobacco and non-medical nicotine products through a global, comprehensive, and consistent approach in order to safeguard tobacco control progress in past decades.

Although rheumatoid arthritis (RA) results in a 50% increased risk of cardiovascular disease mortality, comparable to the risk associated with diabetes mellitus, a significant care gap remains in cardiovascular risk management for this high-risk population. A retrospective cohort study was conducted at a minority-serving institution to assess demographic, clinical, and laboratory data associated with referral to cardiology by rheumatology. The results showed that a minority (5%) of patients were referred to cardiology during an outpatient rheumatology encounter. Patients referred were more likely to be on antihypertensive medication and aspirin. Differences in traditional cardiovascular risk factors such as systolic blood pressure, LDL cholesterol, smoking history, and diabetes mellitus were not significantly associated with being referred. Patients with RA who were evaluated by cardiology were more likely to be started on cardiovascular risk-reducing medications such as antihypertensive, lipid-lowering, and aspirin therapy. This study highlights a care gap in the evaluation and referral of patients with RA and recognizes the improved preventive cardiovascular care received by patients evaluated by a cardiologist.
RESUMEN
Background: Multidisciplinary rounds (MDR) consisting of social workers, dietitians, pharmacists, physical therapists, nurses, and physicians have been implemented at many healthcare institutions to address the complex components of inpatient care. However, little is known on the association of MDR on clinical outcomes across cardiovascular pathologies. This study aimed to investigate the impact of MDR on cardiovascular patients. Methods: Hospital admissions to inpatient cardiology were evaluated prior to (November 2017 to November 2018) and after implementation of MDR (December 2018 to August 2020) at a metropolitan academic medical center. The following outcomes were evaluated: clinical complications (incidence of stroke, gastrointestinal bleed, myocardial infarction, or systemic infection during hospitalization), Length of Stay (LOS), 30-day readmissions and all-cause in-hospital mortality. Secondary outcomes included utilization of physical therapy and dietary services. Results: Admissions were evaluated prior to (N = 1054) and after (N = 1659) MDR implementation. All-cause in-hospital mortality after MDR implementation decreased significantly from 2.8 to 1.6% (P = 0.03). Although the number of complications and LOS decreased, these differences were not statistically significant. No significant change was observed in 30-day readmissions. Significant increase in the utilization of physical therapy (34.2 to 53.5%; P < 0.01) and dietary services (7.2 to 19.3%; P < 0.01) were observed. Conclusion: Multidisciplinary rounds implementation was associated with significantly decreased mortality and positively impacted resource utilization with increased consultations for ancillary services. MDR is a high impact intervention that utilizes existing resources to improve mortality and should be implemented especially for cardiovascular patients. Further investigation into the benefit of MDR across different patient populations and care settings is warranted.
RESUMEN
Background: The mortality from COVID-19 alone cannot account for the impact of the pandemic. Cardiovascular disease (CVD) mortality has increased disproportionately in specific racial/ethnic populations. Objective: This study aimed to characterize how the COVID-19 pandemic impacted the association between CVD mortality and social and demographic factors as characterized by the Social Vulnerability Index (SVI). Methods: Medical Examiner Case Archive of Cook County, Illinois was utilized to identify CVD deaths in 2019 (pre-pandemic) and 2020 (pandemic). Rate ratios (RRs) were used to compare age-adjusted mortality rates (AAMRs). Addresses of deaths were geocoded to Chicago Community Areas. The Spearman's rank correlation coefficient (ρ) test was used to identify the association between SVI and CVD mortality. Results: AAMRs of CVD deaths significantly increased among non-Hispanic Black individuals (AAMRR, 1.1; 95 % CI, 1.1-1.2) and Hispanic individuals (AAMRR, 1.8; 95 % CI, 1.5-2.1) from 2019 to 2020. Among non-Hispanic White individuals, the AAMR did not significantly increase (AAMRR, 1.0; 95 % CI, 0.9-1.1). A significant positive association was observed between SVI and the percentage of non-Hispanic Black residents (ρ = 0.45; P < 0.05), while the inverse was observed with the percentage of non-Hispanic White residents (ρ = -0.77; P < 0.05). A significant positive association between SVI and CVD mortality rate increased (ρ = 0.24 and 0.28; P < 0.05). Conclusions: Significant association between SVI and CVD mortality was strengthened from 2019 to 2020, and CVD mortality increased among non-Hispanic Black and Hispanic populations. These findings demonstrate that the COVID-19 pandemic has led to an exacerbation of health inequities among different racial/ethnic populations resulting in increased CVD mortality.
RESUMEN
Importance: Individuals with systemic lupus erythematosus (SLE) have an increased risk of pregnancy-related complications. However, data on acute cardiovascular complications during delivery admissions remain limited. Objective: To investigate whether SLE is associated with an increased risk of acute peripartum cardiovascular complications during delivery hospitalization among individuals giving birth. Design, Setting, and Participants: This population-based cross-sectional study was conducted with data from the National Inpatient Sample (2004-2019) by using International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) or International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Clinical Modification (ICD-10-CM) codes to identify delivery hospitalizations among birthing individuals with a diagnosis of SLE. A multivariable logistic regression model was developed to report an adjusted odds ratio (OR) for the association between SLE and acute peripartum cardiovascular complications. Data were analyzed from May 1 through September 1, 2022. Exposure: Diagnosed SLE. Main Outcomes and Measures: Primary study end points were preeclampsia, peripartum cardiomyopathy, and heart failure. Secondary end points included ischemic and hemorrhagic stroke, pulmonary edema, cardiac arrhythmias, acute kidney injury (AKI), venous thromboembolism (VTE), length of stay, and cost of hospitalization. Results: A total of 63â¯115â¯002 weighted delivery hospitalizations (median [IQR] age, 28 [24-32] years; all were female patients) were identified, of which 77â¯560 hospitalizations (0.1%) were among individuals with SLE and 63â¯037â¯442 hospitalizations (99.9%) were among those without SLE. After adjustment for age, race and ethnicity, comorbidities, insurance, and income level, SLE remained an independent risk factor associated with peripartum cardiovascular complications, including preeclampsia (adjusted OR [aOR], 2.12; 95% CI, 2.07-2.17), peripartum cardiomyopathy (aOR, 4.42; 95% CI, 3.79-5.13), heart failure (aOR, 4.06; 95% CI, 3.61-4.57), cardiac arrhythmias (aOR, 2.06; 95% CI, 1.94-2.21), AKI (aOR, 7.66; 95% CI, 7.06-8.32), stroke (aOR, 4.83; 95% CI, 4.18-5.57), and VTE (aOR, 6.90; 95% CI, 6.11-7.80). For resource use, median (IQR) length of stay (3 [2-4] days vs 2 [2-3] days; P < .001) and cost of hospitalization ($4953 [$3305-$7517] vs $3722 [$2606-$5400]; P < .001) were higher for deliveries among individuals with SLE. Conclusions and Relevance: This study found that SLE was associated with increased risk of complications, including preeclampsia, peripartum cardiomyopathy, heart failure, arrhythmias, AKI, stroke, and VTE during delivery hospitalization and an increased length and cost of hospitalization.

BACKGROUND: As AF-associated morbidity and mortality are increasing, there is an acute need for improved surveillance and prevention strategies to reduce the impact of AF and related strokes. Specific echocardiographic parameters that can best predict future onset of AF within 3 months are lacking. METHODS: Twenty patients with AF, as identified by presence of ICD-9 diagnosis code, were compared with a control group of twenty age- and sex-matched patients selected from the same clinic population but without a diagnosis of AF. Transthoracic echocardiograms (TTE) obtained within 90 days prior to first documented AF episode (study group) or obtained closest to first clinic visit (control) were selected for review. RESULTS: Baseline characteristics, including age, BMI, presence of hypertension, hyperlipidemia, diabetes, and heart failure were comparable. Increased left atrial (LA) size (end systolic major axis in 2-chamber view: AF 4.62±0.03 vs control 3.79±0.21, P =0.03), increased mitral inflow (E/A ratio: AF 1.35±0.15 vs control 1.06±0.07, P =0.04), and reduced LA global longitudinal strain (AF -2.69±0.26 vs control - 3.59±0.31, P =0.04) were most closely associated with AF compared with the control group. Multivariate logistic regression was used to develop predictive models for AF onset. A combination of imaging and traditional clinical risk factors was the best AF prediction model with AUC of 0.94, which greatly exceeds the current best predictors published. From these parameters, we developed the SMASH2 scoring system for 90- day AF risk estimation. CONCLUSIONS: Risk factors for AF and early features of atrial cardiomyopathy including male sex, hypertension, LA enlargement, reduced mitral inflow, and reduced LA strain are powerful predictors of AF onset within 90 days, and may be used to prognosticate future AF risk.

Myocardial injury is a common complication of the COVID-19 illness and is associated with a worsened prognosis. Systemic hyperinflammation seen in the advanced stage of COVID-19 likely contributes to myocardial injury. Cardiac magnetic resonance imaging (CMR) is the preferred imaging modality for non-invasive evaluation in acute myocarditis, enabling risk stratification and prognostication. Modified scanning protocols in the pandemic setting reduce risk of exposure while providing critical data regarding cardiac tissue inflammation and fibrosis, chamber remodeling, and contractile function. The growing use of CMR in clinical practice to assess myocardial injury will improve understanding of the acute and chronic sequelae of myocardial inflammation from various pathological etiologies.
RESUMEN
Mile Square Health Center (MSHC), a network of Federally Qualified Health Centers (FQHCs) run by the University of Illinois Hospital (UIH) in Chicago, established Drive-Thru and Walk-Up COVID-19 testing sites. The primary aim of the UIH/MSHC testing project was to increase testing capacity in the most affected, racial/ethnic minority communities. More than 7,500 tests were performed over a six-month period. Half of those who were tested were Black and Latinx residents. The majority of those tested at the Walk-Up sites were Black, while "Other" race group tended to get tested in Drive Thru testing sites. Latinx residents had the highest positivity rate, followed by Other race group. Younger age groups were more likely to have higher positivity rates. Overall, UH/MSHC testing results reflected the overall Chicago COVID-19 testing results. Our findings substantiate the need to advocate for equitable resource allocation to counter the disproportionate burden of COVID-19 infection among minority communities. FQHCs were shown to be an effective approach to reduce structural barriers to COVID-19 testing and subsequently reduce disparities. Going forward, FQHCs can be key to ensuring COVID-19 vaccine outreach and dissemination.
RESUMEN
OBJECTIVE: Out-of-Hospital Cardiac Arrest (OHCA) is a global public health problem. There is inadequate data on OHCA in India. The Warangal Area out-of-hospital Cardiac Arrest Registry (WACAR) was planned to understand OHCA in a regional setting in India. METHODS: WACAR is a prospective one-year observational cohort study of OHCA in the Warangal area, Telangana, India. The study included 814 subjects of OHCA of presumed cardiac etiology brought to the Mahatma Gandhi Memorial Hospital during January 1, 2018, and December 31, 2018. The data collected included; standard Utstein variables with additional data on clinical characteristics (modified Utstein template). RESULTS: The majority of OHCA subjects were male with a median age of 60 years, and mostly occurring in residential locations within 1 h of onset of symptoms. Individuals with knowledge of CVD risk factors were more likely to report symptoms before OHCA. Data on resuscitation characteristics were inadequate. CONCLUSIONS: The WACAR study provides baseline data regarding OHCA in a regional setting in India. The study demonstrated barriers involving data collection, patient knowledge of CVD risk factors and disease, and access to healthcare, which; impacted the data registry.

Implantable cardioverter defibrillators (ICDs) have been a relative contraindication to cardiovascular magnetic resonance imaging. Although cardiovascular magnetic resonance provides valuable information regarding scar in patients with ventricular arrhythmias or cardiomyopathy, ICDs in these patients frequently cause artifacts hindering accurate interpretation of both cine and late gadolinium enhancement (LGE) images. We sought to quantify the frequency and severity of artifact on LGE images and assess whether a modified wideband LGE protocol could improve the diagnostic yield of scar identification in agreement with invasive electroanatomic mapping (EAM). Forty-nine patients with ICDs and ventricular tachycardia (VT) or cardiomyopathy underwent CMR (Philips 1.5T), including standard and wideband LGE imaging. A safety algorithm was followed throughout the protocol. Standard and wideband LGE short-axis images were graded using an artifact score on a per-slice basis. LGE on wideband images was compared with EAM in 27 of 49 patients who underwent VT ablation. There were no adverse patient- or device-related events. With standard LGE imaging, 84% of patients demonstrated some degree of hyperenhancement artifact, which persisted in 22% on wideband LGE but with much less extent. Wideband LGE imaging resulted in an increase from 48% to 94% diagnostic-quality slices, with a significant reduction in artifact score, and correlated with EAM in 21 of 27 patients (78%). In conclusion, assessment of standard LGE is markedly limited by artifact in patients with ICD. The use of wideband LGE significantly improves image quality and can accurately localize myocardial scar before VT ablation.

BACKGROUND: The impact of health insurance carrier and socioeconomic status (SES) on the adherence to appropriate use criteria (AUC) for radionuclide myocardial perfusion imaging (MPI) is unknown. HYPOTHESIS: Health insurance carrier's prior authorization and patient's SES impact adherence to AUC for MPI in a fee-for-service setting. METHODS: We conducted a prospective cohort study of 1511 consecutive patients who underwent outpatient MPI in a multi-site, office-based, fee-for-service setting. The patients were stratified according to the 2009 AUC into appropriate/uncertain appropriateness and inappropriate use groups. Insurance status was categorized as Medicare (does not require prior authorization) vs commercial (requires prior authorization). Socioeconomic status was determined by the median household income in the ZIP code of residence. RESULTS: The proportion of patients with Medicare was 33% vs 67% with commercial insurance. The rate of inappropriate use was higher among patients with commercial insurance vs Medicare (55% vs 24%; P < 0.001); this difference was not significant after adjusting for confounders known to impact AUC determination (odds ratio: 1.06, 95% confidence interval: 0.62-1.82, P = 0.82). The mean annual household income in the residential areas of patients with inappropriate use as compared to those with appropriate/uncertain use was $72 000 ± 21 000 vs $68 000 ± 20 000, respectively (P < 0.001). After adjusting for covariates known to impact AUC determination, SES (top vs bottom quartile income area) was not independently predictive of inappropriate MPI use (odds ratio: 0.9, 95% confidence interval: 0.53-1.52, P = 0.69). CONCLUSIONS: Insurance carriers prior authorization and SES do not seem to play a significant role in determining physicians adherence to AUC for MPI.
