An analysis of long-term clinical outcome following the use of excimer laser coronary atherectomy in a large UK PCI center.

BACKGROUND: Excimer laser atherectomy (ELCA) is an established adjunctive technique to facilitate acute success in percutaneous coronary intervention (PCI). Despite this there are a lack of contemporary outcome data, particulary longer-term, forpatients treated with ELCA PCI. AIMS: To evaluate the contemporary use ofELCA in PCI, the frequency of periprocedural complications and the longer-term outcomes associated with ELCA PCI. METHODS: This was a retrospective study that included all patients undergoing PCI (with or without ELCA) between April 2005 and May 2021. Relevant features from all cases were downloaded from the patient record and matched to hospital data on mortality on November 22, 2022. Kaplan Meier curves were used to compare mortality between the ELCA PCI and non-ELCA PCI cohorts with a landmark at 1 year. Multivariable Cox regression was performed to assess whether ELCA PCI was independently associated with long-term mortality. RESULT: There were 21,256 patients in this analysis, of which 448 (2.1%) were treated with ELCA PCI. ELCA PCI was associated with a higher frequency of any periprocedural complication. Median follow-up was 2812 days (IQR, 1577-4245 days) with higher mortality in ELCA PCI (38.2% vs. 29.0%, p < 0.001). However, on multivariable analysis, ELCA PCI was not independently associated with long-term mortality. The TVR frequency in ELCA PCI was 16.7% but TVR was significantly higher for cases of in-stent restenosis (ISR) (29.5%). CONCLUSION: Despite ELCA PCI being used in higher risk populations with complex coronary artery disease there was no long-term increased mortality associated with the use of this device. ELCA PCI for ISR is highly effective and safe although TVR in this cohort remains high in long-term follow-up.

The impact of concomitant chronic total occlusion on clinical outcomes in patients undergoing transcatheter aortic valve replacement: a large single-center analysis.

Background: Coronary artery disease (CAD) is a common finding in patients with severe aortic stenosis undergoing transcatheter aortic valve replacement (TAVR). However, the impact on prognosis of chronic total occlusions (CTOs), a drastic expression of CAD, remains unclear. Methods and results: We retrospectively reviewed 1,487 consecutive TAVR cases performed at a single tertiary care medical center. Pre-TAVR angiograms were analyzed for the presence of a CTO. At the time of TAVR, 11.2% (n = 167) patients had a CTO. There was no significant association between the presence of a CTO and in-hospital or 30-day mortality. There was also no difference in long-term survival. LV ejection fraction and mean aortic gradients were lower in the CTO group. Conclusions: Our analysis suggests that concomitant CTO lesions in patients undergoing TAVR differ in their risk profile and clinical findings to patients without CTO. CTO lesion per se were not associated with increased mortality, nevertheless CTOs which supply non-viable myocardium in TAVR population were associated with increased risk of death. Additional research is needed to evaluate the prognostic significance of CTO lesions in TAVR patients.

Enteral nutrition in children and adolescents who receive extracorporeal membrane oxygenation and its impact on complications and mortality: A systematic review and meta-analysis.

Enteral nutrition (EN) is one method of nutrition support for children and adolescents receiving extracorporeal membrane oxygenation (ECMO) therapy, and there are no guidelines for its use in this population. We conducted a systematic review to determine whether EN is effective and safe in children supported by ECMO. We searched the Cochrane Library database, MEDLINE, and Embase on Ovid in March 2023 to identify studies that evaluated children and adolescents who received ECMO and were treated with EN. Random effects meta-analysis was used to estimate the odds of mortality with EN compared with parenteral nutrition (PN). A total of 14 studies were included in this review with 1650 patients (796 received EN). The median duration of ECMO was 5-10 days, and the median EN initiation time ranged from 23 h to 7 days. The pooled results suggest no significant difference in mortality with EN compared with PN (odds ratio [OR] = 0.77; 95% CI, 0.56-1.05; I2 = 26%). Exclusion of the only study that reported an increase in mortality resulted in a borderline significant reduction in mortality with EN (OR = 0.71; 95% CI, 0.51-1.00; I2 = 26%). The predictors of EN were male sex, older age, heavier weight, greater height, cardiac diagnosis, longer duration of ECMO, and use of venovenous ECMO. Most studies suggest no correlation between EN and complications. EN use in children and adolescents who receive ECMO does not appear to be associated with increased mortality compared with PN and was safe in terms of intestinal complications and feeding intolerance.

Structural Complications Following ST-Elevation Myocardial Infarction: An Analysis of the National Inpatient Sample 2016 to 2020.

ST-elevation myocardial infarction (STEMI) is a life-threatening emergency that can result in cardiac structural complications without timely revascularization. A retrospective study from the National Inpatient Sample included all patients with a diagnosis of STEMI between 2016 and 2020. Primary outcomes of interest were in-hospital mortality, length of stay (LoS), and healthcare costs for patients with and without structural complications. There were 994,300 hospital admissions included in the analysis (median age 64 years and 32.2% female). Structural complications occurred in 0.78% of patients. There was a three-fold increase in patients with cardiogenic shock (41.6% vs. 13.6%) and in-hospital mortality (30.6% vs. 10.7%) in the group with structural complications. The median LoS was longer (5 days vs. 3 days), and the median cost was significantly greater (USD 32,436 vs. USD 20,241) for patients with structural complications. After adjustments, in-hospital mortality was significantly greater for patients with structural complications (OR 1.99, 95% CI 1.73-2.30), and both LoS and costs were greater. There was a significant increase in mortality with ruptured cardiac wall (OR 9.16, 95% CI 5.91-14.20), hemopericardium (OR 3.20, 95% CI 1.91-5.35), and ventricular septal rupture (OR 2.57, 95% CI 1.98-3.35) compared with those with no complication. In conclusion, structural complications in STEMI patients are rare but potentially catastrophic events.

Missed Opportunities in Type 2 Diabetes Mellitus: A Narrative Review.

BACKGROUND: Type 2 diabetes mellitus (T2DM) is a significant health problem around the world. OBJECTIVE: This review aims to define missed opportunities and how they apply to patients with T2DM. METHOD: This narrative review describes the natural history of T2DM and also describes where missed opportunities may arise. RESULTS: Missed opportunities may relate to prevention, early detection, diagnosis, and treatment of diabetes. The cornerstone of T2DM prevention is the control of modifiable risk factors and lifestyle changes to potentially prevent diabetes. Early detection of T2DM is important as it is a chronic condition that can progress rapidly if untreated. Missed opportunities related to the diagnosis of T2DM draw attention to the heterogeneous presentation of diabetes. The condition can be incidentally identified in asymptomatic patients, so all healthcare professionals should be aware of the disease. Furthermore, it is not unexpected that patients with atypical symptoms may have a delay in diagnosis. The treatment-related missed opportunities in T2DM are broad and include self-care, education, remission of T2DM, risk factor management, prevention of complications, medication therapy and compliance, as well as individualized care. Considering patient pathways is a useful approach to evaluate missed opportunities in patient care. CONCLUSION: Missed opportunities are a concept that is not often considered in diabetes care, which calls upon reflection of real-world activities and consideration of whether patient outcomes could have been improved with changes in decision-making. Future studies that aim to improve patient care should consider this concept.

The impact of the site of myocardial infarction on in-hospital outcomes for patients with STEMI.

BACKGROUND: The territory and vessel involved in ST-elevation myocardial infarction (STEMI) is an important and there are limited contemporary studies from the national perspective. METHODS: A retrospective cohort study was undertaken of national representative hospital admission in the National Inpatient Sample with a diagnosis of anterior or non-anterior STEMI between 2017 and 2020. Multiple logistic regression and multiple linear regressions were used to determine if there are any differences in in-hospital mortality, length of stay (LOS) and cost for anterior and non-anterior STEMI. RESULTS: A total of 655 915 admissions with STEMI were included in the analysis (267 920 anterior STEMI, and 387 995 non-anterior STEMI). Non-anterior STEMI was associated with a significant reduction in mortality (OR 0.91 95% CI 0.89-0.99, P  = 0.011) and LOS (coefficient -0.15 95% CI -0.22 to -0.08, P  < 0.001) compared to anterior STEMI but there was no significant difference in healthcare costs (-297 95% CI -688 to 74). Analyses considering the infarct-related artery showed that the worse outcomes were associated with left main lesions and left-sided lesions had worse outcomes than right coronary artery lesions. CONCLUSION: Non-anterior STEMI is associated with reduced mortality and LOS compared to anterior STEMI. Left-sided coronary lesions had worse outcomes, compared to right coronary lesions. STEMI should be considered in terms of the vessel or territory affected, in relation to outcomes and healthcare costs.

Self-expanding versus balloon expandable stent for intracranial arterial stenosis: A systematic review and meta-analysis.

BACKGROUND AND PURPOSE: There are limited data regarding the comparison of balloon expandable stents (BES) and self-expanding stents (SES) for the treatment of intracranial arterial stenosis. METHODS: We conducted a systematic review to identify studies that compared SES and BES in patients with symptomatic intracranial arterial stenosis. Data were extracted from relevant studies found through a search of PubMed, Scopus, and Web of Science until from January 1, 2010 to September 28, 2023. Statistical pooling with random-effects meta-analysis was undertaken to compare the rates/severity of postprocedure stenosis, technical success, 30-day stroke and/or death, cumulative clinical endpoints, and restenosis rates. RESULTS: A total of 20 studies were included. The standardized mean difference (SMD) for postprocedure stenosis (%) was significantly lower (SMD: -0.52, 95% confidence interval [CI]: -0.79 to -0.24, p < .001, 10 studies involving 1515 patients) with BES. The odds for 30-day stroke and/or death were significantly lower (odds ratio [OR] 0.68, 95% CI: 0.50-0.94, p = .019, 15 studies involving 2431 patients), and cumulative clinical endpoints on follow-up were nonsignificantly lower (OR 0.64, 95% CI: 0.30-1.37, p = .250, 10 studies involving 947 patients) with BES. The odds for restenosis during follow-up were significantly lower (OR 0.50, 95% CI: 0.31-0.80, p = .004, 13 studies involving 1115 patients) with BES. CONCLUSIONS: Compared with SES, BES were associated with lower rates of postprocedure 30-day stroke and/or death with lower rates of restenosis during follow up and the treatment of symptomatic intracranial arterial stenosis.

Mechanical thrombectomy with intra-arterial thrombolysis versus mechanical thrombectomy alone in patients with acute ischemic stroke: A systematic review and meta-analysis.

BACKGROUND: There is conflicting evidence as to whether intra-arterial thrombolysis (IAT) adds benefit in patients with acute stroke who undergo mechanical thrombectomy (MT). METHODS: We conducted a systematic review to identify studies that evaluate IAT in patients with acute stroke who undergo MT. Data were extracted from relevant studies found through a search of PubMed, Scopus, and Web of Science until February 2023. Statistical pooling with random effects meta-analysis was undertaken to evaluate odds of functional independence, mortality, and near-complete or complete angiographic recanalization with IAT compared to no IAT. RESULTS: A total of 18 studies were included (3 matched, 14 unmatched, and 1 randomized). The odds ratio (OR) for functional independence (modified Rankin Scale: 0-2) at 90 days was 1.14 (95% confidence interval (CI): 0.95-1.37, p = 0.17, 16 studies involving 7572 patients) with IAT with moderate between-study heterogeneity (I2 = 38.1%). The OR for functional independence with IAT was 1.28 (95% CI: 0.92-1.78, p = 0.15) in studies that were either matched or randomized and 1.24 (95% CI: 0.97-1.58, p = 0.08) in studies with the highest quality score. IAT was associated with higher odds of near-complete or complete angiographic recanalization (OR: 1.65, 95% CI: 1.03-2.65, p = 0.04) in studies that were either matched or of randomized comparisons. CONCLUSION: Although the odds of functional independence appeared to be higher with IAT and MT compared with MT alone, none of the results were statistically significant. A prominent effect of the design and quality of the studies was observed on the association between IAT and functional independence at 90 days.

The impact of COVID-19 and the COVID-19 pandemic on hospitalized patients with STEMI in the United States: insights from the National Inpatient Sample.

BACKGROUND: It is unclear how COVID-19 pandemic affected care and outcomes among patients who are diagnosed with ST-elevation myocardial infarction (STEMI) in the USA. METHODS: We analyzed the data from National Inpatient Sample from 2016 to 2020 and assessed the impact of COVID-19 infection and the COVID-19 pandemic (year 2020) on in-hospital mortality, length of stay (LOS) and hospitalization costs.P. RESULTS: There were 1 050 905 hospitalizations with STEMI, and there was an 8.2% reduction in admissions in 2020. Patients with COVID-19 versus those without had significantly greater in-hospital mortality (45.2% vs. 10.7%; P < 0.001). In 2020, 3.0% of hospitalizations had a diagnosis of COVID-19, and the mortality was 11.5% compared to 10.7% for patients admitted in 2016-2019 period. There was a significantly increased mortality (OR 6.25, 95% CI 5.42-7.21, P < 0.001), LOS (coefficient 3.47, 95% CI 3.10-3.84, P < 0.001) and cost (coefficient 10.69, 95% CI 8.4-12.55, P < 0.001) with COVID-19 infection compared with no infection. There was a borderline difference in mortality (OR 1.04, 95% CI 1.00- 1.09, P = 0.050) but LOS (coefficient -0.21, 95% CI-0.28 to -0.14, P < 0.001) and costs (3.14, 95% CI 2.79 to 3.49, P < 0.001) were reduced in 2020 compared to 2016-2019 period. CONCLUSIONS: In conclusion, in patients hospitalized with STEMI, COVID-19 infection was associated with increased mortality, LOS, and cost but during the pandemic year of 2020 there was a small trend for increased mortality for patients with a diagnosis of STEMI.

The importance of pathways to facilitate early diagnosis and treatment of patients with cardiac amyloidosis.

Cardiac amyloidosis (CA) is a condition caused by extracellular deposition of amyloid fibrils in the heart. It is an underdiagnosed disease entity which can present with a variety of cardiac and non-cardiac manifestations. Diagnosis usually follows an initial suspicion based on clinical evaluation or imaging findings before confirmation with subsequent imaging (echocardiography, cardiac magnetic resonance imaging, 3,3-diphosphono-1,2-propanodicarboxylic acid scintigraphy) in combination with biochemical screening for monoclonal dyscrasia (serum free light chains and serum and urine electrophoresis) and/or histology (bone marrow trephine, fat or endomyocardial biopsy). More than 95% of CA can be classified as either amyloid light-chain (AL) CA or amyloid transthyretin (ATTR) CA; these two conditions have very different management strategies. AL-CA, which may be associated with multiple myeloma, can be managed with chemotherapy agents, autologous stem cell transplantation, cardiac transplant and supportive therapies. For ATTR-CA, there is increasing importance in making an early diagnosis because of novel treatments in development, which have transformed this once incurable disease to a potentially treatable disease. Timely diagnosis is crucial as there may only be a small window of opportunity where patients can benefit from treatment beyond which therapies may be less effective. Reviewing the existing patient pathway provides a basis to better understand the complexities of real-world activities which may be important to help reduce missed opportunities related to diagnosis and treatment for patients with CA. With healthcare provider interest in improving the care of patients with CA, the development of an optimal care pathway for the condition may help reduce delays in diagnosis and treatment and thus enhance patient outcomes.

Gastrointestinal bleeding in chronic kidney disease patients: a systematic review and meta-analysis.

Gastrointestinal bleeding (GIB) is a major cause of mortality in patients with renal failure. We conducted a systematic review of the literature to evaluate the rates, predictors, and outcomes of GIB in patients with chronic kidney disease (CKD). A search of MEDLINE and EMBASE databases was performed, and data were extracted from relevant studies. Statistical pooling was performed to determine the rate of GIB in patients with CKD, and a random-effect meta-analysis was performed to determine the predictors of GIB and mortality in patients with GIB. Twenty-two studies were included in this review, with 7,810,273 patients with CKD included in the analysis. The pooled results of five studies suggested that the rate of GIB in patients with CKD was 2.2%, and among the studies in which patients with CKD underwent endoscopy, the pooled results for GIB were 35.8%. Receipt of dialysis (OR 14.48, 95%CI 4.96-42.32), older age (OR 1.03, 95%CI 1.02-1.05), diabetes mellitus (OR 1.30, 95%CI 1.22-1.39), history of ulcers (OR 1.53, 95%CI 1.03-2.26), and cirrhosis (OR 1.73, 95%CI 1.41-2.12) were significantly associated with GIB. The pooled results suggest a twofold increase in the odds of mortality with GIB, with significant heterogeneity (OR 2.12, 95%CI 1.45-3.10, I2 = 93%). GIB in patients with CKD affects 2% of patients but can be greater in the group of patients who underwent endoscopy. Receipt of dialysis is a strong predictor of GIB, and sustained GIB is associated with a twofold increase in the odds of mortality compared to patients without GIB.

Key pointsThe rate of gastrointestinal bleeding (GIB) in patients with chronic kidney disease (CKD) was 2.2%.The rate of GIB in patients with CKD is higher in those who undergo endoscopy.Dialysis, older age, diabetes mellitus, history of ulcers, and cirrhosis were significantly associated with GIB in CKD.GIB in patients with CKD was associated with a twofold increase in the odds of mortality.

Acute ischemic stroke patients admitted to hospitals that perform percutaneous coronary interventions in the United States.

BACKGROUND: We explored the potential of mechanical thrombectomy (MT) for acute ischemic stroke patients at hospitals that perform percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI) in the United States. METHODS: We analyzed nationally representative data between 2017 and 2020 to determine the numbers, characteristics, and outcomes of acute ischemic stroke patients admitted to hospitals that perform both primary PCI and MT, hospitals that perform primary PCI but not MT and hospitals that perform neither PCI or MT. Multiple logistic regressions were performed to evaluate the effect of hospital type on in-hospital mortality and discharge home (without palliative care). RESULTS: A total of 1,210,415, 1,002,950, and 488,845 acute ischemic stroke patients were admitted to hospitals that performed both primary PCI and MT, performed primary PCI but not MT, or performed neither PCI nor MT, respectively. Compared with hospitals that performed both PCI and MT, the odds of in-hospital mortality were lower in hospitals that performed PCI only (odds ratio (OR) 0.88 95 % confidence interval (CI) 0.86-0.91, p<0.001) and hospitals that performed neither PCI or MT (OR 0.85 95 %CI 0.82-0.89, p<0.0010). There was no significant difference in the odds of discharge home between the three types of hospitals. CONCLUSIONS: Almost 37 % the patients with acute ischemic stroke are admitted to hospitals that perform primary PCI (but not MT) supporting strategies to increase the performance of MT in such hospitals as an option to increase rapid availability of MT in the United States.

Is high sensitivity troponin, taken regardless of a clinical indication, associated with 1 year mortality in critical care patients?

The aim of this study was to assess whether high sensitivity troponin (hs-cTnI) is associated with 1 year mortality in critical care (CC). One year mortality data were obtained from NHS Digital for a consecutive cohort of patients admitted to general CC unit (GCCU) and neuroscience CC unit (NCCU) who had hs-cTnI tests performed throughout their CC admission, regardless of whether the test was clinically indicated. Cox proportional hazards were used to estimate the risk of 1-year mortality. A landmark analysis was undertaken to assess whether any relationship at 1 year was driven by mortality within the first 30 days. A total of 1033 consecutive patients were included. At 1 year 254 (24.6%) patients had died. The admission log(10)hs-cTnI concentration in the entire cohort (HR 1.35 (95% CI 1.05-1.75) p = 0.009 with a bootstrap of 1000 samples) was independently associated with 1 year mortality. On landmark analysis the association with 1 year mortality was driven by 30 day mortality. These results indicate that admission hs-cTnI concentration is independently associated with 1 year mortality in CC and this relationship may be driven by differences in mortality at 30 days.

What Are the Causes of Death among Patients Admitted to a Contemporary Tertiary-Level Cardiology Department? An Analysis of 10 Years of Morbidity and Mortality Meetings.

Despite the efforts to deliver the best evidence-based care, in-hospital death is an inevitable event among some patients hospitalized in cardiology departments. We conducted a retrospective evaluation of mortality events from inpatient admissions to the cardiology department between 2010 and 2019. Data were collected from morbidity and mortality meeting presentations that evaluated comorbidities, medical history, treatments, and causes of death for the overall cohort and according to age group and sex. There were 1182 registered deaths. The most common causes of death among patients were acute myocardial infarction (AMI, 53.0%), heart failure (HF, 11.7%), cardiac arrest (CA, 6.6%), HF with complication/defined cardiomyopathy (6.3%), and sepsis (4.4%). We observed a decline in deaths from AMI from 61.9% in 2010 to 46.7% in 2019, while there was a clear increase in deaths from HF (11.1% in 2010 to 25.9% in 2019). Compared to patients ≥65 years, younger patients were more likely to have died from CA (15.7% vs. 4.3%, p < 0.001) and other cardiac reasons (3.0% vs. 0.4%, p < 0.001). The majority of deaths were due to AMI, HF, and CA. We observed a significant declining trend in the proportion of deaths due to AMI in recent years, with an increase in deaths due to HF.

Association between troponin level and medium-term mortality in 20 000 hospital patients.

INTRODUCTION: Cardiac troponin (cTn) concentrations above the manufacturer recommended upper limit of normal (ULN) are frequently seen in hospital patients without a clinical presentation consistent with type 1 myocardial infarction, and the significance of this is uncertain. The aim of this study was to assess the relationship between medium-term mortality and cTn concentration in a large consecutive hospital population, regardless of whether there was a clinical indication for performing the test. METHOD: This prospective observational study included 20 000 consecutive in-hospital and outpatient patients who had a blood test for any reason at a large teaching hospital, and in whom a hs-cTnI assay was measured, regardless of the original clinical indication. Mortality was obtained via NHS Digital. RESULTS: A total of 20 000 patients were included in the analysis and 18 282 of these (91.4%) did not have a clinical indication for cardiac troponin I (cTnI) testing. Overall, 2825 (14.1%) patients died at a median of 809 days. The mortality was significantly higher if the cTnI concentration was above the ULN (45.3% vs 12.3% p<0.001 log rank). Multivariable Cox analysis demonstrated that the log10 cTnI concentration was independently associated with mortality (HR 1.76 (95% CI 1.65 to 1.88)). Landmark analysis, excluding deaths within 30 days, showed the relationship between cTnI concentration and mortality persisted. CONCLUSION: In a large, unselected hospital population, in 91.4% of whom there was no clinical indication for testing, cTnI concentration was independently associated with medium-term cardiovascular and non-cardiovascular mortality in the statistical model tested.

Mechanical thrombectomy in patients with acute ischemic stroke in the USA before and after time window expansion.

BACKGROUND: In 2018, the time window for mechanical thrombectomy eligibility in patients with acute ischemic stroke increased from within 6 hours to within 24 hours of symptom onset. The purpose of this study was to evaluate the effect of window expansion on procedural and hospital volumes and patient outcomes at a national level. METHODS: We conducted a retrospective cohort study of patients with acute ischemic stroke undergoing mechanical thrombectomy using data from the National Inpatient Sample. We compared the numbers of mechanical thrombectomy procedures and performing hospitals between 2017 and 2019 in the USA, and the proportion of patients discharged home/self-care, those with in-hospital mortality and post-procedural intracranial hemorrhage (2019 vs 2017) after adjustment for potential confounders. RESULTS: The number of patients with ischemic stroke who underwent mechanical thrombectomy increased from 16 960 in 2017 to 28 120 in 2019. There was an increase in the number of hospitals performing mechanical thrombectomy (501 in 2017, 585 in 2019) and those performing ≥50 procedures/year (97 in 2017, 199 in 2019; P<0.001). The odds of in-hospital mortality decreased (OR 0.79, 95% CI 0.66 to 0.94, P=0.008) and the odds of intracranial hemorrhage increased (OR 1.18, 95% CI 1.06 to 1.31, P=0.003) in 2019 compared with 2017, with no change in odds of discharge to home. CONCLUSIONS: The window expansion for mechanical thrombectomy for patients with acute ischemic stroke was associated with an increase in the numbers of mechanical thrombectomy procedures and performing hospitals with a reduction of in-hospital mortality in the USA.

Cerebral infarction and in-hospital mortality for patients admitted to hospital with intracardiac thrombus: insights from the National Inpatient Sample.

The factors associated with cerebral infarction and mortality in patients hospitalized with intracardiac thrombus are unknown. A retrospective cohort study was undertaken of nationally representative hospital admissions in the National Inpatient Sample with a diagnosis of intracardiac thrombus between 2016 to 2019. Multiple logistic regressions were used to define factors associated with cerebral infarction and in-hospital mortality. There were a total of 175,370 admissions for patients with intracardiac thrombus and 10.1% patients had cerebral infarction (n = 17,675). Intracardiac thrombus represented 4.4% of primary diagnosis for admissions while circulatory conditions (65.4%), infection (5.9%), gastrointestinal conditions (4.4%), respiratory conditions (4.4%) and cancer (2.2%) were the other prevalent primary diagnoses. All-cause mortality was higher for patients with cerebral infarction (8.5% vs 4.8%). The five factors most associated with cerebral infarction were nephrotic syndrome (OR 2.67 95%CI 1.05-6.78), other thrombophilia (OR 2.12 95%CI 1.52-2.95), primary thrombophilia (OR 1.99 95%CI 1.52-2.53), previous stroke (OR 1.61 95%CI 1.47-1.75) and hypertension (OR 1.41 95%CI 1.27-1.56). The strongest independent predictors of death were heparin induced thrombocytopenia (OR 2.45 95%CI 150-4.00), acute venous thromboembolism (OR 2.03 95%CI 1.78-2.33, p < 0.001) acute myocardial infarction (OR 1.95 95%CI 1.72-2.22), arterial thrombosis (OR 1.75 95%CI 1.39-2.20) and cancer (OR 1.57 95%CI 1.36-1.81). Patients with intracardiac thrombus are at risk of cerebral infarction and in-hospital mortality. Nephrotic syndrome, thrombophilia, previous stroke, hypertension, and heparin induced thrombocytopenia were associated with cerebral infarction, while acute venous thromboembolism, acute myocardial infarction, and cancer were predictors of mortality.

In-hospital outcomes and conditions in patients with acute coronary syndrome and coronary artery aneurysms who undergo percutaneous coronary intervention.

BACKGROUND: Coronary artery aneurysms (CAA) are uncommon, often incidental findings in patients with acute coronary syndrome (ACS) that represent a management challenge due to as there is a paucity of literature in this area. METHODS: We analyzed the National Inpatient Sample database from 2016 to 2020 by including all patients with the admission diagnosis of the ACS who underwent percutaneous coronary intervention (PCI). We sought to evaluate the association of CAA with other relevant systemic conditions and determine the impact of CAA on in-hospital outcomes. RESULTS: Among 1,733,655 hospital admission with ACS who underwent PCI, 2675 had CAA. There was a 2-fold increase in odds of CAA if the patient had coronary artery dissection (OR 2.05 95%CI 1.12-3.75, p = 0.020) or extracoronary aneurysm (OR 2.47 95%CI 1.46-4.16, p = 0.001) and a 3-fold increase in odds if they had a systematic inflammatory disorder (OR 3.24 95%CI 2.08-5.07, p < 0.001). CAA was not associated with increased odds of mortality (OR 1.22 95%CI 0.76-1.95, p = 0.42), bleeding (OR 1.29 95%CI 0.86-1.95, p = 0.22), acute stroke (OR 0.91 95%CI 0.40-2.07, p = 0.83), major adverse cardiac and cerebrovascular events (OR 1.08 95%CI 0.72-1.61, p = 0.71) or cardiac complications (OR 0.85 95%CI 0.49-1.47, p = 0.55). However, it was significantly associated with increased odds of vascular complications (OR 2.17 95%CI 1.47-3.19, p < 0.001). CONCLUSIONS: For patients with ACS who undergo PCI, the presence of CAA is associated with greater odds of vascular complications but after adjustments there was no difference in mortality or other complications. In this population, CAA is more prevalent in patients with coronary dissection, extracoronary aneurysms and systemic inflammatory disorders.

Intra-arterial thrombolysis as adjunct to mechanical thrombectomy in acute ischemic stroke patients in the United States: A case control analysis.

BACKGROUND: Although observational studies have reported favorable clinical outcomes associated with intra-arterial thrombolysis as adjunct to mechanical thrombectomy, the cost and length of hospitalization associated with this intervention has not been studied. METHODS: We analyzed the nationally representative data of the United States data from Nationwide Inpatient Sample (NIS) to compare hospitalization cost and duration in addition to other outcomes in patients receiving (n = 1990) with those not receiving intra-arterial thrombolysis (n = 1990) in acute ischemic stroke patients undergoing mechanical thrombectomy using a case control design matched for age, gender, and presence of aphasia, hemiplegia, neglect, coma/stupor, hemianopsia and dysphagia. RESULTS: There was no difference in the median hospitalization cost in patients treated with intra-arterial thrombolysis compared with those not treated with intra-arterial thrombolysis: $36,992 [28,361 to 54,336] versus $35,440 [24,383 to 50,438], (regression coefficient 2,485 [-1,947 to 6,917], p = 0.27). There was no difference in the median length of hospitalization in patients treated with intra-arterial thrombolysis compared with those not treated with intra-arterial thrombolysis: 6 days [3 to 10] versus 6 days [4 to 10], (regression coefficient -0.34 [-1.47 to 0.80], p = 0.56). There was no difference in odds of home-discharge (OR 1.02 95%CI 0.72-1.43, p = 0.93) or post-procedural intracranial hemorrhage (OR 1.16 95%CI 0.83-1.64, p = 0.39) between the two groups. CONCLUSIONS: We did not observe an increase in the cost or length of hospitalization associated with the use of intra-arterial thrombolysis as adjunct to mechanical thrombectomy in acute ischemic stroke patients. If the ongoing randomized clinical trials demonstrate therapeutic efficacy in reducing death or disability, this intervention has a high likelihood of being beneficial overall.
