RESUMEN
INTRODUCTION: Stanford Type A Aortic Dissection (TAAD) is characterized by a high in-hospital mortality rate and necessitates urgent surgical intervention. While socioeconomic status is known to influence health-care outcomes, its specific association with TAAD remains underexplored. This study aimed to investigate the population-based association between socioeconomic status with TAAD repair outcomes using a national registry. METHODS: Patients who had TAAD repair were identified in National Inpatient Sample from Q4 2015-2020. National Inpatient Sample stratified estimated median household income of residents within a patient's ZIP code. Patients residing in neighborhoods of incomes in the lowest and highest quartiles were selected as the study cohorts. Multivariable logistic regressions were used to compare in-hospital outcomes, adjusted for demographics, comorbid conditions, hospital characteristics, primary payer status, and transfer status. RESULTS: Compared to patients from high-income neighborhoods, patients in low-income communities had higher risks of mortality (adjusted odds ratio [aOR] 1.45, P = 0.01), acute kidney injury (aOR 1.225, P = 0.03), and infection (aOR 1.474, P = 0.02), as well as longer wait from admission to operation (24.96 ± 2.64 versus 18.00 ± 1.92 h, P = 0.03) and longer length of stay (15.06 ± 0.38 versus 13.80 ± 0.36 d, P = 0.01). In contrast, patients from low-income communities had less risk of hemorrhage/hematoma (aOR 0.691, P < 0.01) and lower total hospital charge (428,746 ± 10,658 versus 487,017 ± 16,770 US dollars, P < 0.01). CONCLUSIONS: Evidence suggests patients from lower-income communities may have limited access to health care and treatment delays, leading to higher mortality and complications. The underlying reasons for these disparities in economically disadvantaged communities warrant further investigation, which could focus on health-care accessibility, timely detection of TAAD, and prompt transfers to specialized centers.

BACKGROUND: Stanford Type A Aortic Dissection (TAAD) is an emergent condition with high in-hospital mortality. Gender disparity in TAAD has been a topic of ongoing debate. This study aimed to conduct a population-based examination of gender disparities in short-term TAAD outcomes using the National/Nationwide Inpatient Sample (NIS) database, the largest all-payer database in the US. METHODS: Patients undergoing TAAD repair were identified in NIS from the last quarter of 2015-2020. Multivariable logistic regressions were used to compare in-hospital outcomes between male and female patients, adjusted for demographics, comorbidities, hospital characteristics, primary payer status, and transfer status. RESULTS: There were 1454 female and 2828 male patients identified who underwent TAAD repair. Female patients presented with TAAD were at a more advanced mean age (64.03 ± 13.81 vs. 58.28 ± 13.43 years, p < 0.01) and had greater comorbid burden. Compared to male patients, female patients had higher risks of in-hospital mortality (17.88% vs. 13.68%, adjusted odds ratio (aOR) = 1.266, p = 0.01). In addition, female patients had higher pericardial complications (20.29% vs. 17.22%, aOR = 1.227, p = 0.02), but lower acute kidney injury (AKI; 39.96% vs. 53.47%, aOR = 0.476, p < 0.01) and venous thromboembolism (VTE; 1.38% vs. 2.65%, aOR = 0.517, p = 0.01). Female patients had comparable time from admission to operation and transfer-in status, longer hospital stays, but fewer total hospital expenses. CONCLUSION: Female patients were 1.27 times as likely to die in-hospital after TAAD repair but had less AKI and VTE. While there is no evidence suggesting delay in TAAD repair for female patients, the disparities might stem from other differences such as in care provided or intrinsic physiological variations.

BACKGROUND: Type A aortic dissection (TAAD) is an emergent condition that warrants immediate intervention. Peripheral artery disease (PAD) is a prevalent disease associated with worse outcomes in various cardiovascular procedures. However, it remains unclear whether PAD influences outcomes of TAAD repair. This study aimed to undertake a population-based analysis to assess impact of PAD on in-hospital outcomes following TAAD repair. METHODS: Patients underwent TAAD repair were identified in National Inpatient Sample from Q4 2015 to 2020. Multivariable logistic regressions were used to compare in-hospital outcomes between patients with and without PAD, adjusted for demographics, socioeconomic status, primary payer status, hospital characteristics, comorbidities, and transfer/admission status. RESULTS: 1525 patients with PAD and 2757 non-PAD patients underwent TAAD. PAD patients had higher mortality (18.62% vs 13.17%, aOR = 1.287, p = .01), AKI (51.41% vs 47.48%, aOR = 1.222, p < .01), infection (10.69% vs 8.02%, aOR = 1.269, p = .03), and vascular complication (7.28% vs 3.77%, aOR = 1.846, p < .01) but lower risks of pericardial complications (15.21% vs 19.95%, aOR = 0.696, p < .01). In addition, patients with PAD had longer time from admission to operation (1.29 ± 3.95 vs 0.70 ± 2.09 days, p < .01), longer LOS (14.92 ± 13.98 vs 13.41 ± 11.66 days, p = .01), and higher hospital charge (499,064 ± 519,405 vs 409,754 ± 405,663 US dollars, p < .01). CONCLUSION: PAD was independently associated with worse outcome after TAAD repair. The elevated mortality rate could be attributed to the delay in surgery, which may be related to preoperative peripheral malperfusion syndrome that is common in PAD patients. A balance between preoperative management and immediate TAAD repair might be essential to prevent the increased mortality risk from treatment delays among PAD patients.
RESUMEN
BACKGROUND: Alcohol abuse (AA) has s high prevalence, affecting 10 to 15 million Americans. While AA was demonstrated to negatively impact cardiovascular health, limited evidence from existing studies presents conflicting findings regarding the effects of AA on coronary artery bypass grafting (CABG) outcomes. This study aimed to compare the in-hospital outcomes after CABG between AA and non-AA patients. METHODS: Patients who underwent CABG were identified in National Inpatient Sample from Q4 2015-2020. Exclusion criteria included age<18 years and concomitant procedures. A 1:3 propensity-score matching was used to address differences in demographics, socioeconomic status, primary payer status, hospital characteristics, comorbidities, and transfer/admission status between AA and non-AA patients. In-hospital outcomes after CABG were examined. RESULTS: There were 5694 (3.39%) AA patients who underwent CABG. After matching, 17,315 from 162,488 non-AA patients were matched to all AA patients. AA and non-AA patients had comparable mortality (1.64% vs 1.55%, p = 0.67) and MACE (2.46% vs 2.56%, p = 0.73). However, AA patients had higher cardiogenic shock (8.31% vs 7.43%, p = 0.03), mechanical ventilation (11.51% vs 7.96%, p < 0.01), hemorrhage/hematoma (57.49% vs 54.75%, p < 0.01), superficial (0.99% vs 0.61%, p < 0.01) and deep wound complications (0.37% vs 0.18%, p = 0.02), reopen surgery for bleeding control (0.92% vs 0.63%, p = 0.03), transfer out (21.00% vs 16.38%, p < 0.01), longer time from admission to operation (p < 0.01), longer length of stay (p < 0.01), and higher hospital charge (p < 0.01). CONCLUSION: While AA was not found to be linked with in-hospital mortality or MACE after CABG, it was independently associated with postoperative complications. These findings could enhance preoperative risk stratification for AA patients and inform postoperative management following CABG.
RESUMEN
There is limited data on the effect of socioeconomic status (SES) on transcatheter (TAVR) and surgical aortic valve replacement (SAVR) outcomes for aortic stenosis (AS). This study conducted a population-based analysis to assess the influence of SES on valve replacement outcomes. Patients with AS undergoing TAVR or SAVR were identified in National Inpatient Sample from Q4 2015-2020. Multivariable logistic regressions were used to compare in-hospital outcomes between patients living in neighborhoods of income at the lowest and highest quartiles. Of 613,785 AS patients, 9.77% underwent TAVR and 10.13% had SAVR. These rates decline with lower neighborhood income levels, with TAVR/SAVR ratio also declining in lower-income areas. Excluding concomitant procedures, 58,064 patients received isolated TAVR (12,355 low-income and 15,212 high-income) and 43,694 underwent isolated SAVR (10,029 low-income and 10,811 high-income). Low-income patients, in both TAVR and SAVR, were younger but had more comorbid burden. For isolated TAVR, outcomes were similar across income groups. However, for isolated SAVR, low-income patients experienced higher in-hospital mortality (aOR = 1.44, p < 0.01), pulmonary (aOR = 1.13, p = 0.01), and renal complications (aOR = 1.14, p < 0.01). They also had more transfers, longer waits for operations, and extended hospital stays. Lower-income communities had reduced access to TAVR and SAVR, with TAVR accessibility being particularly limited. When given access to TAVR, patients from lower-income neighborhoods had mostly comparable outcomes. However, patients from low-income communities faced worse outcomes in SAVR, possibly due to delays in treatment. Ensuring equitable specialized healthcare resources including expanding TAVR access in economically disadvantaged communities is crucial.

BACKGROUND: Coronary artery disease (CAD) and valvular disease frequently coexist due to similar pathophysiology. Effort has been dedicated to comprehending the outcomes of concomitant coronary revascularization and valve replacement procedures. However, the understanding of how prior valve replacement affects the outcomes of coronary artery bypass grafting (CABG) remains limited. Thus, this study aimed to conduct a population-based examination of the in-hospital outcomes in patients with previous valve replacement in CABG. METHODS: Patients who underwent CABG were identified in the National Inpatient Sample in the USA from Q4 2015-2020. Patients with ageâ¯<â¯18â¯years and concomitant procedures were excluded. A 1:3 propensity-score matching was used to address differences in demographics, socioeconomic status, primary payer status, hospital characteristics, comorbidities, and transfer/admission status between patients with and without previous valve replacement. In-hospital postoperative outcomes were assessed. RESULTS: There were 514 patients with previous valve replacement who underwent CABG, who were matched to 1588 out of 167,668 controls. After matching, patients with valve replacement had mostly comparable in-hospital outcomes except for a higher risk of vascular complications (1.75â¯% vs 0.57â¯%, pâ¯=â¯0.02), a longer length of stay (10.90⯱â¯7.04â¯days vs 9.95⯱â¯6.53â¯days, pâ¯=â¯0.01), and higher hospital charges (275,465⯱â¯229,088 US dollars vs 231,648⯱â¯189,938 US dollars, pâ¯<â¯0.01). CONCLUSION: For short-term outcomes, CABG is generally safe for patients who have undergone previous valve replacement, although there is an increased risk of vascular complications that may warrant additional attention. The findings of this study can be valuable for preoperative risk assessment of patients who have had valve replacement and are considering CABG.
RESUMEN
BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a common comorbidity that has been linked to higher mortality and respiratory complications in cardiac surgery. However, the postoperative outcomes for COPD patients undergoing Type A Aortic Dissection (TAAD) repair remain unexplored. Thus, this study aimed to assess the impact of COPD on in-hospital outcomes of TAAD repair in a national registry. METHODS: Patients undergoing TAAD repair were identified in National Inpatient Sample from the last quarter of 2015-2020. Multivariable logistic regressions were used to compare in-hospital outcomes between patients with and without COPD, where demographics, comorbidities, hospital characteristics, primary payer status, and transfer status were adjusted. RESULTS: There were 701 (16.37 %) COPD patients and 3581 (83.63 %) non-COPD patients who went under TAAD repair, where the prevalence of COPD was higher than in the general population (6 %). COPD and non-COPD patients have comparable rates of in-hospital mortality (14.69 % vs 15.19 %, aOR 1.016, 95 CI 0.797-1.295, p = 0.9) and there was no indication of delayed surgery. However, COPD patients had a higher risk of mechanical ventilation (37.80 % vs 31.42 %, aOR 1.521, 95 CI 1.267-1.825, p < 0.01) and a higher rate of transferring out to other facilities (38.37 % vs 32.23 %, aOR 1.271, 95 CI 1.054-1.533, p = 0.01). In addition, COPD patients had a longer hospital length of stay (14.28 ± 11.32 vs 13.85 ± 12.78 days, F = 5.61, p = 0.01). CONCLUSION: The presence of COPD could be a risk factor for the development of aortic dissection. However, outcomes for COPD patients were largely similar to those without COPD. These findings can be valuable for preoperative assessments and tailoring perioperative care for COPD patients undergoing TAAD repair.
RESUMEN
Individuals affected by human immunodeficiency virus (HIV) have a growing demand for coronary artery bypass grafting (CABG) due to heightened risk for cardiovascular diseases and extended life expectancy. However, CABG outcomes in HIV patients are not well-established, with insights only from small case series studies. This study conducted a comprehensive, population-based examination of in-hospital CABG outcomes in HIV patients. Patients underwent CABG were identified in National Inpatient Sample from Q4 2015-2020. Patients with age < 18 years and concomitant procedures were excluded. A 1:5 propensity-score matching was used to address preoperative group differences. Among patients who underwent CABG, 613 (0.36%) had HIV and were matched to 3119 out of 167,569 non-HIV patients. For selected HIV patients, CABG is relatively safe, presenting largely similar outcomes. After matching, HIV and non-HIV patients had comparable in-hospital mortality rates (2.13% vs. 1.67%, p = 0.40). Risk factors associated with mortality among HIV patients included previous CABG (aOR = 14.32, p = 0.01), chronic pulmonary disease (aOR = 8.24, p < 0.01), advanced renal failure (aOR = 7.49, p = 0.01), and peripheral vascular disease (aOR = 6.92, p = 0.01), which can be used for preoperative risk stratification. While HIV patients had higher acute kidney injury (AKI; 26.77% vs. 21.77%, p = 0.01) and infection (8.21% vs. 4.18%, p < 0.01), other complications were comparable between the groups.
