RESUMO
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.
RESUMO
BACKGROUND: PROTECT IV is a current enrolling randomized controlled trial evaluating high-risk percutaneous coronary intervention (HR-PCI) with prophylactic Impella versus no Impella to reduce the composite primary endpoint of all-cause death, stroke, myocardial infarction (MI), or cardiovascular hospitalization. In a PROTECT IV-like cohort of patients who underwent HR-PCI without Impella, we aimed to report the rate of major adverse events to determine whether the trial is adequately powered. METHODS AND RESULTS: A total of 700 patients meeting similar inclusion/exclusion criteria of PROTECT IV who underwent HR-PCI without Impella at a single tertiary center from 2008 to 2022 were included in the analysis. The composite rates of all-cause death, MI, target lesion revascularization, and target vessel revascularization at 1, 2, and 3 years were estimated using the Kaplan-Meier method, and the results were used to calculate the sample size under the constant hazard ratio assumption and expected number of events to be observed used in planning PROTECT IV. The primary endpoint occurred in 30.8 % of patients at 2 years. PROTECT IV assumes a hazard ratio of 0.75 using a multivariate Cox regression, which, under a 5 % level and 90 % power, yields 516 events. This implies a 2-year primary outcome rate of 50 % for the non-Impella arm. CONCLUSION: Therefore, PROTECT IV estimates that a sample size of 1252 patients is required for Impella to be declared superior to the non-Impella group. Using our observed 2-year outcome of 30.8 %, we estimate that PROTECT IV requires 1966 patients, demonstrating that PROTECT IV is probably underpowered.
RESUMO
Bioprosthetic aortic valve thrombosis is frequently detected after transcatheter and surgical aortic valve replacement due to advances in cardiac computed tomography angiography technology and standardized surveillance protocols in low-surgical-risk transcatheter aortic valve replacement trials. However, evidence is limited concerning whether subclinical leaflet thrombosis leads to clinical adverse events or premature structural valve deterioration. Furthermore, there may be net harm in the form of bleeding from aggressive antithrombotic treatment in patients with subclinical leaflet thrombosis. This review will discuss the incidence, mechanisms, diagnosis, and optimal management of bioprosthetic aortic valve thrombosis after transcatheter aortic valve replacement and bioprosthetic surgical aortic valve replacement.

Spontaneous coronary artery dissection (SCAD) is a rare cause of ST-segment elevation myocardial infarction (STEMI), predominantly affecting women. Because primary percutaneous coronary intervention (PPCI) is reserved for a select group of patients, vulnerable and minority patients may experience delays in appropriate management and adverse outcomes. We examined the racial differences in the outcomes for patients with SCAD who underwent PPCI for STEMI. Records of patients aged ≥18 years who underwent PPCI for SCAD-related STEMI between 2016 and 2020 were identified from the National Inpatient Sample database. Clinical, socioeconomic, and hospital characteristics were compared between non-White and White patients. Weighted multivariate analysis assessed the association of race with inpatient mortality, length of stay (LOS), and hospitalization costs. The total weighted estimate of patients with SCAD-STEMI who underwent PPCI was 4,945, constituting 25% non-White patients. Non-White patients were younger (56 vs 60.7 years, p <0.001); had a higher prevalence of diabetes, acute renal failure, and obesity; and were more likely to be uninsured and be in the lowest income group. Inpatient mortality (7.7% vs 8.4%, p = 0.74) and hospitalization costs ($34,213 vs $31,858, p = 0.27) were similar for non-White and White patients, and the adjusted analysis did not show any association between the patients' race and inpatient mortality (odds ratio 0.60, 95% confidence interval [CI] 0.32 to 1.13, p = 0.11) or hospitalization costs (ß [ß coefficient]: 215, 95% CI -4,193 to 4,623, p >0.90). Similarly, there was no association between the patients' race and LOS (incident rate ratio 1.20, 95% CI 1.00 to 1.45, p = 0.054). The weighted multivariate analysis showed that age; clinical co-morbidities such as diabetes, acute renal failure, valvular dysfunction, and obesity; low-income status; and hospitalization in the western region were associated with adverse outcomes. In conclusion, our study does not show any differences in inpatient mortality, LOS, and hospitalization costs between non-White and White patients who underwent PPCI for SCAD-related STEMI.

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.

BACKGROUND: Coronary microvascular dysfunction (CMD) has been implicated as a potential mechanism in the pathophysiology of different clinical presentations, including ischemia and no obstructive coronary artery disease (INOCA), myocardial infarction and nonobstructive coronary arteries (MINOCA), stress cardiomyopathy, heart failure, and myocarditis. There are limited data about the role of CMD in cancer therapy-related cardiovascular toxicities. CASE PRESENTATIONS: Four women with a diagnosis of active cancer receiving treatment who developed subsequent MINOCA or INOCA presented for cardiac catheterization. Upon coronary angiography showing no obstructive coronary arteries, coronary function testing was performed to evaluate for CMD. METHODS: Coronary physiology was assessed measuring non-hyperemic (resting full-cycle ratio [RFR]) and hyperemic (fractional flow reserve [FFR]) indices using a physiologic pressure wire. The wire also measured coronary flow reserve (CFR), index of microcirculatory resistance (IMR), and RFR using thermodilution technology. CMD was confirmed if the CFR was <2.5 and the IMR was >25. RESULTS: Among 4 patients with diagnosis of active cancer presenting with chest pain, there was no evidence of obstructive coronary artery disease, leading to separate diagnoses of INOCA, MINOCA, stress cardiomyopathy, and myocarditis. We found CMD in 2 patients (1 with INOCA and 1 with immune checkpoint inhibitor-related myocarditis). CONCLUSIONS: CMD may play a role in cardiovascular toxicities. Further coronary physiology studies are needed to understand the mechanisms of cancer therapy-related cardiovascular toxicity and CMD, as well as optimal preventive and treatment options.
RESUMO
Advances in cardiology have led to improved survival among patients with congenital heart disease (CHD). Racial disparities in cardiovascular and maternal outcomes are well known and are likely to be more profound among pregnant women with CHD. Using the 2001 to 2018 National Inpatient Sample, we identified all hospitalizations for delivery among women ≥ 18 years of age with CHD. Unadjusted and adjusted between-race differences in adverse maternal cardiovascular, obstetric, and fetal events were assessed using logistic regression models. During the study period, we identified 52,711 hospitalizations for delivery among women with concomitant CHD. Of these, 66%, 11%, and 16% were White, Black, and Hispanic, respectively. Obstetric complications and fetal adverse events were higher among Blacks compared to Whites and Hispanics (44% vs. 33% vs. 37%, p < .001; 36% vs. 28% vs. 30%, p < .001), respectively. No between-race differences were observed in overall cardiovascular adverse events (27% vs. 24% vs. 23%, p < .21). However, heart failure was significantly higher among Black women (3.6% vs. 1.7% vs. 2.2%, p = 0.001). While a lower income quartile was associated with higher rates of adverse outcomes, adjustment for income did not attenuate the adverse impact of race. Black females with CHD diagnoses were more likely to experience adverse obstetric, fetal events, and heart failure compared to White and Hispanic women irrespective of their income status. Further research is needed to identify causes and devise interventions to mitigate racial disparities in the care of pregnant women with CHD.
RESUMO
Background: Vascular access closure is essential in large-bore arteriotomy procedures, such as transcatheter aortic valve replacement. âSuture-based devices are frequently used for vascular access closure. MANTA (Teleflex) is a collagen plug-based device used to achieve hemostasis with evolving efficacy and safety data. This study aimed to evaluate plug-based versus suture-based closure devices following large-bore arteriotomy procedures. Methods: We conducted a systematic review searching PubMed, Cochrane Library, and ClinicalTrials.gov (inception through November 2021) for studies evaluating plug-based versus suture-based closure devices following large-bore arteriotomy procedures. We performed a meta-analysis comparing the length of stay, device failure, mortality, bleeding, and vascular complications between these 2 types of devices. Results: Eleven studies (2 randomized controlled trials and 9 observational studies) with a total of 3123 patients were included in this analysis. Compared with suture-based devices, plug-based devices were associated with a significant decrease in the length of stay (standardized mean difference: -0.14; 95% CI, -0.25 to -0.03) and vascular closure device failure (odds ratio, 0.63; 95% CI, 0.44-0.91) following the procedure. There were no significant differences in all-cause mortality, major or minor bleeding, and major or minor vascular complications between plug-based and suture-based closure devices. Conclusions: Plug-based vascular closure devices were associated with a shorter length of stay and lower risk of device failure following large-bore arteriotomy procedures without differences in mortality, bleeding, or vascular complications than suture-based closure devices.
RESUMO
Background: The role of atherectomy in treating femoropopliteal disease has been evolving rapidly. However, the clinical efficacy and safety of adjunctive atherectomy to percutaneous balloon angioplasty (BA) (plain balloon and drug-coated BA) remains controversial. We sought to perform a meta-analysis comparing atherectomy plus balloon angioplasty (ABA) versus BA alone in treating femoropopliteal disease. Methods: We searched PubMed, Cochrane Central Register of Clinical Trials, EMBASE, and ClinicalTrials.gov (from inception through January 10, 2022) for studies comparing ABA versus BA for femoropopliteal disease. We used a random-effects model to calculate risk ratio (RR) with 95% CIs. Target lesion revascularization (TLR), primary patency, and bailout stenting were the primary outcomes. Results: Nine studies with 699 patients were included (4 randomized and 5 retrospective studies). Compared to BA alone, the ABA group showed a significant decrease in TLR driven by nonrandomized studies (RR 0.59; 95% CI, 0.40-0.85; P = .005) and bailout stenting (RR, 0.32; 95% CI, 0.21-0.48; P < .0001). There was no significant difference in TLR when the analysis was performed including only randomized trials. There was no significant difference in the primary patency between the 2 groups (RR, 1.04; 95% CI, 0.95-1.14; P = .37). Conclusions: Data from randomized trials suggest that compared with BA alone, the combination of atherectomy and BA showed no difference in TLR or primary patency. In observational studies, TLR and bailout stenting were reduced in ABA group but there was no difference in primary patency. Further studies are needed to investigate the clinical outcomes of atherectomy combined with BA in femoropopliteal lesions compared with BA alone.
