ABSTRACT

Background: Intracoronary imaging-guided percutaneous coronary intervention (PCI) is associated with improved outcomes compared with angiography-guided PCI. Data on racial/ethnic, sex, and economic disparities in the utilization and outcomes of intracoronary imaging in the United States are scarce. Methods: We analyzed the National Inpatient Sample (2016-2020) to examine racial/ethnic, sex, and economic differences in the utilization of intracoronary imaging among patients who underwent PCI. Trends, in-hospital mortality, and safety of intracoronary imaging were also assessed. Results: Among 2,212,595 weighted hospitalizations for PCI, 204,735 (9.2%) included intracoronary imaging. The utilization rate of intracoronary imaging was similar in Black and Hispanic patients compared with White patients (9.8% vs 10.2% vs 10.0%; P = .68) and lower for women compared with men (10.0% vs 10.3%; P = .01) and for patients with low and medium income compared with high income (9.2% vs 10.0% vs 12.5%; P < .01). In multivariable regression analysis, low and medium income were independently associated with lower intracoronary imaging use compared with high income (both P < .01). From 2016 through 2020, the use of intracoronary imaging in PCI increased significantly in all racial/ethnic, sex, and economic groups (all P trend < .01). Among patients who underwent PCI with intracoronary imaging, Black race was associated with higher odds of acute kidney injury compared with White race (adjusted odds ratio, 1.40; 95% CI, 1.25-1.57). In-hospital mortality was similar between different racial/ethnic, sex, and economic groups. Conclusions: Low and medium income are independently associated with lower intracoronary imaging use in PCI compared with high income. Further studies are needed to identify effective strategies to mitigate economic disparities in intracoronary imaging use.

ABSTRACT

Background: Disparities in access to care cause negative health consequences for underserved populations. Economic disparities in structural heart disease (SHD) interventions are not well characterized. Objectives: The objective of this study was to evaluate economic disparities in the utilization and outcomes of SHD interventions in the United States. Methods: We queried the National Inpatient Sample (2016-2020) to examine economic disparities in the utilization, in-hospital outcomes, length of stay, and cost of SHD interventions among patients ≥65 years of age. Outcomes were determined using logistic regression models. Results: A total of 401,005 weighted hospitalizations for transcatheter aortic valve replacement, left atrial appendage occlusion, transcatheter mitral valve repair, and transcatheter mitral valve replacement were included. Utilization rates (number of procedures performed per 100,000 hospitalizations) were higher in patients with high income compared with medium and low income for transcatheter aortic valve replacement (559 vs 456 vs 338), left atrial appendage occlusion (148 vs 136 vs 99), transcatheter mitral valve repair (65 vs 54 vs 41), and transcatheter mitral valve replacement (7.7 vs 6.7 vs 1.2) (all P < 0.01). Low- and medium-income patients had distinctive demographic and clinical risk profiles compared with high-income patients. There were no significant differences in the adjusted in-hospital mortality, key complications, or length of stay between high-, medium-, and low-income patients following any of the 4 SHD interventions. High-income patients incurred a modestly higher cost with any of the 4 SHD interventions compared with medium- and low-income patients. Conclusions: Economic disparities exist in the utilization of SHD interventions in the United States. Nonetheless, adjusted in-hospital outcomes were comparable among high-, medium-, and low-income patients. Multifaceted implementation strategies are needed to attenuate these utilization disparities.

ABSTRACT

Background: Data on racial/ethnic and sex disparities in the utilization and outcomes of tricuspid valve surgery (TVS) in the United States are scarce. The authors aimed to evaluate the impact of race/ethnicity and sex on the utilization and outcomes of TVS. Methods: The authors analyzed the National Inpatient Sample database from 2016 to 2020 to identify hospitalizations for TVS. Racial/ethnic and sex disparities in TVS outcomes were determined using logistic regression models. Results: Between 2016 and 2020, 19 395 hospitalizations for TVS were identified. The utilization rate (number of surgeries/100,000 hospitalizations) was lower in Black and Hispanic patients compared with White patients for surgical tricuspid valve repair (STVr) (331 versus 493 versus 634, P<0.01) and surgical tricuspid valve replacement (STVR) (312 versus 601 versus 728, P<0.01). Similarly, the utilization rate was lower for women compared with men for STVr (1021 versus 1364, P<0.01) and STVR (930 versus 1,316, P<0.01). Compared to White men undergoing TVS, all women had lower odds of acute kidney injury [adjusted odds ratio (aOR) 0.65, 95% CI 0.55-0.78] and higher odds of blood transfusion (aOR 1.30, 95% CI 1.07-1.59), and Black men had higher odds of blood transfusion (aOR 1.59, 95% CI 1.08-2.35). In-hospital mortality and other surgical complications were similar between all groups (all P>0.05). Conclusions: Significant racial/ethnic and sex disparities exist in the utilization of TVS in the United States. Further studies are needed to understand the reasons for these disparities and to identify effective strategies for their mitigation.

ABSTRACT

BACKGROUND: Cardiogenic shock (CS) is associated with significant morbidity and mortality. Sex differences in the outcomes and management of cardiogenic shock are not well established. The primary objective of this study is to investigate the differences inik cardiogenic shock outcomes between males and females. METHODS: A systematic review and meta-analysis were conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology. Studies were searched via the MEDLINE/PubMed, EMBASE, and Cochrane Central Register of Controlled Trials databases from inception to December 2022. RESULTS: The analysis included 24 studies comprising 1,567,660 patients. Compared to females, males with CS had a significantly lower risk of in-hospital all-cause mortality (risk ratio [RR] 0.88, 95 % confidence interval [CI] 0.85-0.90, p < 0.001) and 1-year mortality (RR 0.90, 95 % CI 0.89-0.92, p < 0.001). Males were more likely to undergo percutaneous coronary intervention (RR 1.21, 95 % CI 1.13-1.31, p < 0.0001) and intra-aortic balloon pump placement (RR 1.21, 95 % CI 1.11-1.32, p < 0.0001), with no significant sex differences in the use of extracorporeal membrane oxygenation or Impella. During the index hospitalization, males were at higher risk of arrhythmias (RR 1.18, 95 % CI 1.05-1.34, p = 0.003) and less likely to develop acute kidney injury (RR 0.86, 95 % CI 0.79-0.94, p < 0.001). CONCLUSION: Men have a lower all-cause mortality risk in cardiogenic shock. Addressing disparities in management is crucial for improving CS outcomes, especially for women.

ABSTRACT

BACKGROUND: Severe aortic stenosis (AS) is the most common valvular disease in the USA. Patients undergoing urgent or emergent transcatheter aortic valve replacement (TAVR) have worse clinical outcomes than those undergoing non-urgent procedures. No studies have examined the impact of procedural TAVR timing on outcomes in AS complicated by acute heart failure (AHF). AIMS: We aimed to evaluate differences in in-hospital mortality and clinical outcomes between early (<48 h) vs. late (≥48 h) TAVR in patients hospitalized with AHF using a real-world US database. METHODS: We queried the National Inpatient Sample database to identify hospitalizations with a diagnosis of AHF, aortic valve disease, and a TAVR procedure (2015-2020). The associations between TAVR timing and clinical outcomes were examined using logistic regression model. RESULTS: A total of 25,290 weighted AHF hospitalizations were identified, of which 6855 patients (27.1 %) underwent early TAVR, and 18,435 (72.9 %) late TAVR. Late TAVR patients had higher in-hospital mortality rate (2.2 % vs. 2.8 %, p < 0.01) on unadjusted analysis but no significant difference following adjustment for demographic, clinical, and hospital characteristics [aOR 1.00 (0.82-1.23)]. Late TAVR was associated with higher odds of cardiac arrest (aOR 1.50, 95 % CI: 1.18-1.90) and use of mechanical circulatory support (aOR 2.05, 95 % CI: 1.68-2.51). Late TAVR was associated with longer hospital stay (11 days vs. 4 days, p < 0.01) and higher costs ($72,851 vs. $53,209, p < 0.01). CONCLUSION: Early TAVR was conducted in approximately 25 % of the AS patients admitted with AHF, showing improved in-hospital outcomes before adjustment, with no significant differences observed after adjustment.

ABSTRACT

BACKGROUND: A significant proportion of patients requiring mitral valve (MV) intervention have undergone prior coronary artery bypass grafting (CABG). Reoperative heart surgery is associated with increased risk. AIMS: To evaluate the utilization and outcomes of transcatheter versus surgical MV interventions in patients with prior CABG. METHODS: We queried the Nationwide Readmission Database (2016-2021) to identify adults with prior CABG hospitalized for transcatheter or surgical MV intervention. In-hospital outcomes were compared using multivariable regression and propensity-matching analyses. Readmissions were compared using Cox proportional hazards regression model. RESULTS: Of 305,625 weighted hospitalizations for MV intervention, 23,506 (7.7%) occurred in patients with prior CABG. From 2016-2021, the use of transcatheter MV interventions increased among patients with prior CABG (72 to 191 for repair and 6 to 45 for replacement per 100,000 hospitalizations, both ptrend<0.001). Compared with surgical MV repair and replacement, transcatheter MV repair and replacement were associated with similar in-hospital mortality (adjusted odds ratio [aOR] 0.44, 95% confidence interval [CI] 0.20-1.03 for repair; aOR 0.61, 95% CI 0.38-1.02 for replacement) and 180-day heart failure readmissions (adjusted hazard ratio [aHR] 1.56, 95% CI 0.85-2.87 for repair; aHR 1.15, 95% CI 0.63-2.09 for replacement) and lower stroke, acute kidney injury, permanent pacemaker placement, length of stay, and nonhome discharges, respectively. Vascular complications were higher with transcatheter versus surgical MV replacement. CONCLUSIONS: Transcatheter MV interventions are increasingly used as the preferred modality of MV intervention in patients with prior CABG and are associated with similar in-hospital mortality and 180-day heart failure readmissions compared with surgical MV interventions.

ABSTRACT

A patient presenting with acute ischemic stroke associated with patent foramen ovale (PFO) had concurrent deep vein thrombosis, pulmonary embolism, and new-onset atrial fibrillation. Upon initiation of anticoagulation therapy, the patient developed hemorrhagic transformation of the stroke. The patient's multiple potential sources of embolic stroke were treated with concomitant left atrial appendage occlusion and PFO closure through the PFO, made possible by using the Steerable Amulet Sheath under 3D-intracardiac echocardiography guidance.

ABSTRACT

Introduction and importance: Chest pain is a frequent reason patients seek medical attention. The broad spectrum of potential etiologies makes determining the underlying cause of chest pain complex. Among cardiovascular etiologies, aortitis is a rare but life-threatening possibility that should be considered in the differential diagnosis. Case presentation: A 53-year-old female with a history of smoking presented with progressively worsening chest and epigastric pain over several weeks. She had seen multiple physicians previously for the same symptoms with unremarkable work-ups. Physical examination was notable for severe tenderness upon palpation of her lower abdomen. The electrocardiogram and troponins were unremarkable. Computed tomography of the abdomen revealed aneurysmal dilatation of the abdominal aorta, soft tissue thickening, and surrounding inflammatory stranding, consistent with aortitis. Infectious and autoimmune work-ups were unremarkable. Intravenous steroids were initiated, and her symptoms improved significantly. Her aortitis was attributed to inflammation secondary to chronic smoking. Clinical discussion: Aortitis is a rare condition with varied clinical presentations. Etiologies of aortitis include infection and non-infectious inflammation. Diagnosis of aortitis requires a thorough clinical assessment and prompt imaging of the aorta, with computed tomography being the preferred imaging modality. Conclusion: Evaluation for cardiovascular chest pain must extend beyond an electrocardiogram and troponin level. Imaging should be considered in patients with atypical symptoms. Aortitis is a rare but important diagnosis requiring immediate treatment.

ABSTRACT

Background: Outcomes of device-detected AF remain unclear in individuals without a prior history of AF. Methods: A meta-analysis was conducted to evaluate outcomes in individuals with no prior history of AF who experienced device-detected AF. Outcomes assessed were clinical AF, thromboembolism and all-cause mortality. A fixed-effects model was used to calculate RRs with 95% CI. Results: Compared to individuals who did not experience device-detected AF, those who did had increased risks of clinical AF (RR 3.33, 95% CI [1.99.5.57]; p<0.0001) and thromboembolic events (RR 2.21; 95% CI [1.72.2.85]; p<0.0001). The risk of all-cause mortality was similar between both groups (RR 1.19; 95% CI [0.95.1.49]; p=0.13). Subgroup analysis revealed an increased risk of thromboembolic events among device-detected AF .24 hours (RR 12.34; 95% CI [2.70.56.36]). Conclusion: While there is an increased risk of clinical AF and thromboembolism in individuals with device-detected AF, mortality was insignificant.

ABSTRACT

PURPOSE: Persistent microvascular obstruction (MVO) after successful percutaneous coronary intervention (PCI) in acute ST segment elevation myocardial infarction (STEMI) has been well-described. MVO predicts lack of recovery of left ventricular function and increased mortality. Sonothrombolysis utilizing diagnostic ultrasound induced cavitation of commercially available microbubble contrast has been effective at reducing infarct size and improving left ventricular ejection fraction (LVEF) when performed both pre- and post-PCI. However, the effectiveness of post-PCI sonothrombolysis alone after successful PCI has not been demonstrated. METHODS: A prospective randomized controlled trial was performed in 50 consecutive consenting patients with anterior STEMI who underwent a continuous microbubble infusion immediately following successful PCI. Intermittent high mechanical index (MI) impulses were applied only in the sonthrombolysis group. Delayed enhancement magnetic resonance imaging (MRI) was performed at 48 h and again at 6-8 weeks to assess for differences in infarct size, LVEF, and MVO. RESULTS: There were no differences between groups in age, gender, and cardiovascular risk factors. Significant (> 2 segments) MVO following successful PCI was observed in 66% of patients. Although sonothrombolysis reduced the extent of MVO acutely, there were no differences in infarct size, LVEF, or extent of MVO by MRI at 48 h. Twenty-eight patients returned for a follow up MRI at 6-8 weeks. LVEF improved only in the sonothrombolysis group (∆LVEF 7.81 ± 4.57% with sonothrombolysis vs. 1.77 ± 7.02% for low MI only, p = .011). CONCLUSION: Post-PCI sonothrombolysis had minimal effect on reducing myocardial infarct size but improved left ventricular systolic function in patients with acute anterior wall STEMI.

ABSTRACT

BACKGROUND: Culprit-only percutaneous coronary intervention (PCI) is commonly performed for acute coronary syndrome (ACS) with multivessel coronary artery disease (MVD) in the elderly. Complete revascularization has been shown to benefit the general population, yet its safety and efficacy in older patients are uncertain. METHODS: Following PRISMA guidelines, we systematically searched PubMed, Embase, and Cochrane databases for randomized controlled trials (RCTs) comparing complete versus culprit-only PCI in patients ≥65 years old with ACS and MVD. The primary outcome was major adverse cardiovascular events (MACE). Secondary outcomes included myocardial infarction (MI), ischemia-driven revascularization (IDR), all-cause mortality, and cardiovascular mortality. Data were pooled using a random effects model with a restricted maximum likelihood estimator to generate risk ratios (RRs). RESULTS: Five RCTs with 4105 patients aged ≥65 years were included. Compared with culprit-only PCI, complete revascularization reduced MI (RR 0.65; 95 % CI 0.49-0.85; p < 0.01). MACE (RR 0.75; 95 % CI 0.54-1.05; p = 0.09) and IDR (RR 0.41; 95 % CI 0.16-1.04; p = 0.06) were not significantly different between both strategies among those aged ≥65. However, there was a significant reduction in MI (RR 0.69; 95 % CI 0.49-0.96; p-value = 0.03), MACE (RR 0.78; 95 % CI 0.65-0.94; p < 0.01), and IDR (RR 0.60; 95 % CI 0.41-0.89; p < 0.01) in those aged ≥75. CONCLUSIONS: In elderly patients aged ≥65 years with ACS and MVD, a strategy of complete revascularization by PCI reduces MI compared to culprit-only PCI with no significant difference in MACE and IDR. However, complete revascularization reduced MI, MACE, and IDR in those aged ≥75 years suggesting a possible benefit in this age group.

ABSTRACT

Coronary artery disease is the most common cause of heart failure, which is the leading cause of cardiovascular-related death worldwide. There are insufficient data to make strong recommendations for percutaneous coronary intervention (PCI) in patients with severe ischemic left ventricular systolic dysfunction (LVSD). In that context, we performed a meta-analysis to compare the outcomes of PCI with those of optimal medical therapy alone in patients with severe ischemic LVSD. A systematic search was conducted in PubMed, EMBASE, and ClinicalTrials.gov from inception to December 2023. Our outcome of interest was all-cause mortality in patients undergoing PCI vs medical therapy. We used random effects models to aggregate data and to calculate pooled incidence and relative risk with 95% CIs. Four studies including 2 randomized controlled trials with 2080 patients (PCI, 1082; optimal medical therapy, 998) were included. All-cause mortality did not differ significantly between the groups: 168 patients (15.5%) in the PCI group vs 200 patients (20.0%) in the optimal medical therapy group (relative risk, 0.88; 95% CI, 0.75-1.09; P=.25). In conclusion, the available evidence indicates that PCI does not improve all-cause mortality in patients with severe LVSD without lifestyle-limiting anginal symptoms. Further data are needed to identify subgroups of patients better served by each modality.

ABSTRACT

BACKGROUND: Although anemia is common in patients with myocardial infarction (MI), management remains controversial. We quantified the association of anemia with in-hospital outcomes and resource utilization in patients admitted with MI using a large national database. METHODS: All hospitalizations with a primary diagnosis code for acute MI in the National Inpatient Sample (NIS) between 2014 and 2018 were identified. Among these hospitalizations, patients with anemia were identified using a secondary diagnosis code. Data on demographic and clinical variables were collected. Outcomes of interest included in-hospital adverse events, length of stay (LOS), and total cost. Multivariable logistic regression and generalized linear models were used to evaluate the relationship between anemia and outcomes. RESULTS: Among 1,113,181 MI hospitalizations, 254,816 (22.8%) included concomitant anemia. Anemic patients were older and more likely to be women. After adjustment for demographics and comorbidities, anemia was associated with higher mortality (7.1 vs. 4.3%; odds ratio 1.09; 95% confidence interval [CI] 1.07-1.12, p < 0.001). Anemia was also associated with a mean of 2.71 days longer LOS (average marginal effects [AME] 2.71; 95% CI 2.68-2.73, p < 0.05), and $ 9703 mean higher total costs (AME $9703, 95% CI $9577-$9829, p < 0.05). Anemic patients who received blood transfusions had higher mortality as compared with those who did not (8.2% vs. 7.0, p < 0.001). CONCLUSION: In MI patients, anemia was associated with higher in-hospital mortality, adverse events, total cost, and length of stay. Transfusion was associated with increased mortality, and its role in MI requires further research.

ABSTRACT

Introduction and importance: While vaping has increased significantly among young individuals, the effects of vape aerosol constituents on cardiac electrophysiological dynamics remain unknown. Case presentation: A 22-year-old female with a history of energy vaping presented with cardiac arrest. Found to have no pulse, CPR was started and an initial rhythm of ventricular tachycardia was obtained. Shock was administered with a follow-up rhythm of ventricular fibrillation. She was emergently defibrillated and entered atrial fibrillation with rapid ventricular response. Toxicology and troponins were all negative. Left heart catheterization and cardiac MRI were unremarkable. She was discharged with an external defibrillation vest and a tentative plan for outpatient electrophysiology study in the setting of negative work-up for cardiopulmonary arrest. Clinical discussion: Vaping-induced sudden cardiac arrest may be attributed to a reduction in cardiac repolarization reserve. Exposure to vegetable glycerin and propylene glycol, substances present in nearly all vape products, have been found to incite arrhythmias and disrupt cardiac conduction in animals. Acrolein, an aldehyde byproduct of glycerin, has also been found to induce arrhythmias due to autonomic dysfunction. Increased intracellular calcium concentration and free radical damage, which occur as a result of inhaling particulate matter generated from e-cigarettes, further propagates the risk of arrhythmia. Conclusion: The effects of inhaling vape aerosols remain not fully understood. While there is a perceived notion that nicotine-free aerosols may be harmless, that remains unclear. Further studies are needed to evaluate proarrhythmogenic effects and autonomic dysfunction from the various chemical substances present in vape aerosols.
