The utility of geriatric nutritional risk index to predict outcomes in chronic limb-threatening ischemia.

OBJECTIVES: To assess geriatric nutritional risk index (GNRI) in patients with chronic limb-threatening ischemia (CLTI). BACKGROUND: The prevalence of CLTI continues to rise, with major amputation and mortality remaining prominent. Frailty is a vital risk factor for adverse outcomes in cardiovascular care. The GNRI is a nutrition-based surrogate for frailty that has been utilized in Southeast Asia to predict adverse events in CLTI. It has not yet been evaluated in a primarily Western population, nor in the context of wound healing. METHODS: Between 8August 2017 and April 2019, we identified patients undergoing endovascular interventions for CLTI at our institution, categorized into low GNRI (≤ 94, frail) versus normal GNRI (> 94, reference). We analyzed the risks of major adverse limb events (MALE), its individual components [mortality, major amputation, and target vessel revascularization (TVR)], amputation free survival (AFS), and wound healing using Kaplan-Meier and multivariate cox-proportional hazard regression analyses. RESULTS: A total of 255 patients were included in the analysis, with follow up of 14 ± 9.1 months. Lower GNRI was associated with higher cumulative event rates for MALE (71.0% vs. 43.3%, p < 0.001), mortality (34.3% vs. 15.2%, p < 0.001), major amputation (31.2% vs. 15.8%, p = 0.002), and freedom from AFS (56.0% vs. 28.2%, p < 0.001). There was a trend toward lower TVR and higher wound healing with higher GNRI score. CONCLUSIONS: Our single-center, retrospective evaluation of GNRI (as a surrogate for frailty) correlated with increased risks of MALE, mortality, and major amputation. Future directions should focus not only on the recognition of these patients, but risk-factor modification to optimize long-term outcomes.

Percutaneous mechanical thrombectomy and extracorporeal membranous oxygenation: A case series.

BACKGROUND: Massive or high-risk pulmonary embolism (PE) is a potentially life-threatening diagnosis with significant morbidity and mortality if treatment is delayed. Extracorporeal membrane oxygenation (ECMO) and large bore thrombectomy (LBT) in isolation have been used to stabilize and treat patients with massive PE, however, literature describing the combination of both modalities is lacking. We present a case series involving 9 patients who underwent combined ECMO and LBT and their outcomes. METHODS: This was a retrospective chart review of patients with confirmed PE, who underwent LBT and ECMO. We retrospectively captured clinical, therapeutic, and outcome data at the time of pulmonary embolism response team (PERT) activation and during the follow-up period for up to 90 days. RESULTS: Nine patients who had PERT activation with confirmed PE diagnosis have undergone combined LBT and ECMO initiation since the advent of our PERT program. The median age was 57 (range 28-68) years. Six patients out of 9 (55%) had cardiac arrest before therapy. All patients exhibited right heart strain on computed tomography and echocardiogram. The median ECMO duration was 5 days (range 2.3-11.6 days), with mean hospitalization of 16.1 days (range 1.5-30.9). Mortality was 22% at 90-day follow-up period. CONCLUSION: Patients with massive pulmonary embolism who suffer cardiac arrest have significant morbidity and mortality. ECMO in combination with LBT is a viable treatment option for patients with significant hemodynamic compromise.

Routine Use of the "Penumbra" Thrombectomy Device in Myocardial Infarction: A Real-World Experience-ROPUST Study.

Objectives: Evaluation of the safety and efficacy of the Penumbra device as an adjunct to percutaneous coronary intervention (PCI) in patients with myocardial infarction (MI) and a large thrombus burden that requires thrombectomy. Background: For patients with acute MI, PCI is the primary reperfusion method. Large thrombus burden has always been a limitation of successful reperfusion. However, the use of current aspiration devices has been associated with an increased incidence of stroke. Methods: We performed a retrospective chart review at the University Hospitals Medical Center in Cleveland. Our study included data from patients who underwent PCI for ST segment elevation myocardial infarction (STEMI) and non-ST segment elevation myocardial infarction (NSTEMI) assisted by the Penumbra Cat RX device (a wide-lumen thrombus aspiration catheter) between May 2019 and February 2021. The primary outcome was the final thrombolysis in myocardial infarction (TIMI) flow. The secondary endpoints were a composite of adverse cardiac events at 6 months. About 50% of the patients did undergo transfemoral PCI as per preference of individual operators. The Penumbra thrombectomy device can be used both by radial and femoral approach and does not need any different guide catheter use. Results: TIMI flow 3 was achieved in 111 patients (90.2%). The secondary endpoint occurred in 11 patients (8.9%, 3 MI, 8 heart failure hospitalizations). There were no stroke events or device-related complications. The door-to-balloon time was not affected by usage of the Penumbra device. Failure in the restoration of TIMI 3 flow was associated with the use of balloon angioplasty prior to the application of the Penumbra device, leading to distal embolization. Conclusions: The Penumbra Cat RX provides safe and effective thrombus removal with better clinical outcomes, even in high-risk patients with acute coronary syndrome.

Recurrent ventricular septal defect following closure CorMatrix: A case report.

Ventricular septal ruptures are an uncommon complication following acute myocardial infarction. Operative repair, utilizing a patch for closure of the defect, is the primary treatment modality to achieve hemodynamic stability. The use of an extracellular matrix derived from small intestinal submucosa as a scaffold for tissue repair is becoming increasingly common. Here, we present the case of a 58-year-old female found to have a ventricular septal rupture and posterior left ventricular aneurysm following late presentation after a myocardial infarction that required operative repair with a CorMatrix patch. Upon readmission for dyspnea and poor exercise tolerance several months later, the patch was subsequently found to have near-completely reabsorbed. There is a paucity of long-term outcomes data following the use of CorMatrix for septal defects, with rare reports of such reabsorption. Further study is required to identify the incidence and implications of such findings.

Multi-variable biomarker approach in identifying incident heart failure in chronic kidney disease: results from the Chronic Renal Insufficiency Cohort study.

AIMS: Heart failure (HF) is one of the leading causes of cardiovascular morbidity and mortality in the ever-growing population of patients with chronic kidney disease (CKD). There is a need to enhance early prediction to initiate treatment in CKD. We sought to study the feasibility of a multi-variable biomarker approach to predict incident HF risk in CKD. METHODS AND RESULTS: We examined 3182 adults enrolled in the Chronic Renal Insufficiency Cohort (CRIC) without prevalent HF who underwent serum/plasma assays for 11 blood biomarkers at baseline visit (B-type natriuretic peptide [BNP], CXC motif chemokine ligand 12, fibrinogen, fractalkine, high-sensitivity C-reactive protein, myeloperoxidase, high-sensitivity troponin T (hsTnT), fibroblast growth factor 23 [FGF23], neutrophil gelatinase-associated lipocalin, fetuin A, aldosterone). The population was randomly divided into derivation (n = 1629) and validation (n = 1553) cohorts. Biomarkers that were associated with HF after adjustment for established HF risk factors were combined into an overall biomarker score (number of biomarkers above the Youden's index cut-off value). Cox regression was used to explore the predictive role of a biomarker panel to predict incident HF. A total of 411 patients developed incident HF at a median follow-up of 7 years. In the derivation cohort, four biomarkers were associated with HF (BNP, FGF23, fibrinogen, hsTnT). In a model combining all four biomarkers, BNP (hazard ratio [HR] 2.96 [95% confidence interval 2.14-4.09]), FGF23 (HR 1.74 [1.30-2.32]), fibrinogen (HR 2.40 [1.74-3.30]), and hsTnT (HR 2.89 [2.06-4.04]) were associated with incident HF. The incidence of HF increased with the biomarker score, to a similar degree in both derivation and validation cohorts: from 2.0% in score of 0% to 46.6% in score of 4 in the derivation cohort to 2.4% in score of 0% to 43.5% in score of 4 in the validation cohort. A model incorporating biomarkers in addition to clinical factors reclassified risk in 601 (19%) participants (352 [11%] participants to higher risk and 249 [8%] to lower risk) compared with clinical risk model alone (net reclassification improvement of 0.16). CONCLUSION: A basic panel of four blood biomarkers (BNP, FGF23, fibrinogen, and hsTnT) can be used as a standalone score to predict incident HF in patients with CKD allowing early identification of patients at high-risk for HF. Addition of biomarker score to clinical risk model modestly reclassifies HF risk and slightly improves discrimination.

Proportionate and Absolute Vascular Disease Mortality by Race and Sex in the United States From 1999 to 2019.

Background Despite the known significant morbidity and mortality associated with cardiovascular disease and peripheral vascular disease (PVD), contemporary data describing racial demographics in PVD mortality are scarce. Methods and Results Using the multiple causes of death file from the Centers for Disease Control and Prevention's Wide-Ranging Online Data for Epidemiologic Research, we analyzed the trends of age-adjusted mortality (AAMR) for PVD and its subtypes (aortic aneurysm/dissection, arterial thrombosis, venous thrombosis/disease, pulmonary embolism), by race and sex between 1999 and 2019. Of the 17 826 871 deaths attributed to cardiovascular disease, a total of 888 187 (5.0%) PVD deaths were analyzed during the study period (12.4% Black, 85.6% White). Between 1999 and 2019, AAMR for PVD decreased by 52% (24.8-11.8 per 100 000 people) in the overall population. Despite a decrease in the overall mortality across all race and sex groups, Black men and Black women continued to have higher mortality for PVD (1.5×), aortic dissection (1.8×), arterial thrombosis (1.3×), and venous thrombosis/disease (2.0×) mortality compared with White men and White women in 2019. While there was a 53% decrease in PVD among White individuals (AAMR 24.5-11.5 per 100 000), there was only a 43% decrease (30.0-17.1) in PVD AAMR in Black individuals between 1999 and 2019. The ratio of PVD AAMR increased from 1.2 (1999) to 1.5 (2019) in Black men/White men and from to 1.3 (1999) to 1.5 (2019) in Black women/White women. Similar trends were noted in aortic dissection (Black men/White men, 1.2-1.8; and Black women/White women, 1.5-1.7), arterial thrombosis (Black men/White men, 1.0-1.3; and Black women/White women, 0.9-1.3), and venous thrombosis/disease (Black men/White men, 1.7-1.8; and Black women/White women, 1.7-2.0). Conclusions In this retrospective review of death certificate data in the United States, we demonstrate continued significant disparities between Black and White populations in PVD mortality and its subtypes. Future studies should investigate etiologies and social determinants of PVD mortality.

Non-invasive Imaging in the Evaluation of Cardiac Allograft Vasculopathy in Heart Transplantation: A Systematic Review.

Cardiac allograft vasculopathy (CAV) is the leading cause of long-term graft dysfunction in patients with heart transplantation and is linked with significant morbidity and mortality. Currently, the gold standard for diagnosing CAV is coronary imaging with intravascular ultrasound during traditional invasive coronary angiography. Invasive imaging, however, carries increased procedural risk and expense to patients in addition to requiring an experienced interventionalist. With the improvements in non-invasive cardiac imaging modalities such as transthoracic echocardiography, computed tomography, magnetic resonance imaging and positron emission tomography, an alternative non-invasive imaging approach for the early detection of CAV may be feasible. In this systematic review, we explored the literature to investigate the utility of non-invasive imaging in diagnosis of CAV in >3000 patients across 49 studies. We also discuss the strengths and weaknesses for each imaging modality. Overall, all 4 imaging modalities show good to excellent accuracy for identifying CAV with significant variations across studies. Majority of the studies compared non-invasive imaging with invasive coronary angiography without intravascular imaging. In summary, non-invasive imaging modalities offer an alternative approach to invasive coronary imaging for CAV. Future studies should investigate longitudinal non-invasive protocols in low-risk patients after heart transplantation.

Reported Pericardial Toxicities Associated with Acute Myelogenous Leukemia Treatments: A Pharmacovigilance Analysis of the FDA Adverse Reporting Database.

Acute myelogenous leukemia (AML) is one of the most common leukemias experienced in adults and conveys significant morbidity and mortality. While the traditional anthracycline based treatments of AML involves cytarabine, developments in alternatives (liposomal cytarabine, fludarabine, cladribine, azacitidine, decitabine), and targeted agents (midostaurin, gilteritinib, enasidenib, ivosidenib, gemtuzumab ozogamicin, and venetoclax) exist. Multiple cardiovascular adverse events, notably pericardial toxicity, have been observed in small studies; however, to date little is known about the comparative pericardial toxicity among these newer regimens. Due to the paucity of data, we sought to investigate the reported pericardial events and mortality associated with treatments for AML. Utilizing the Food and Drug Administration (FDA) Adverse Events Reporting System (FAERS), we identified all adverse events associated with FDA approved treatments for AML (2002-2022). Pericardial events were defined as pericarditis, pericardial effusion and tamponade. We excluded any individuals with age <18 years old. Logistic regression was utilized to identify factors associated with pericardial events. Out of 94,262 reported adverse events, 675 pericardial toxicities were included (243 pericarditis, 479 tamponade). Pericardial events occurred less often in Cladribine (0.3%, P < 0.001), fludarabine (0.4%, P < 0.001), Venetoclax (0.3%, P < 0.001), enasidenib (0.3%, P value < 0.001), and ivosidenib (0.3%, P < 0.001) compared to Cytarabine (0.9%). Tamponade events occurred significantly less often in cladribine (0.1%, P < 0.001), fludarabine (0.4%, P = 0.001), enasidenib (0.1%, P = 0.006), ivosidenib (0.1%, P = 0.01), and venetoclax (0.1%, P < 0.001) compared to cytarabine 0.7%. After adjusting for age and sex, Cladribine (reporting odds ratio [ROR] 0.35 [95% CI 0.18-0.68], P = 0.008) and Fludarabine (ROR 0.65 [0.45-0.92], P = 0.03), venetoclax (ROR 0.57 [0.41-0.79], P < 0.001) remained significantly associated with lower incidence of reported pericardial events. While cytarabine has been the routinely used and/or drug of choice for induction chemotherapy for AML, alternatives like cladribine may have a greater safety profile regarding pericardial toxicities. Future studies should be directed at further investigating cardiovascular safety profiles of AML induction therapy.

Seizure-Associated ST Elevation Myocardial Infarction in Absence of Plaque Rupture.

Acute coronary syndrome (ACS) is a very common cause of morbidity and mortality in the U.S. Here, we present a case of acute ST elevation myocardial infarction (STEMI) in the setting of seizure activity. In this rare case, we have data from optical coherence tomography (OCT) that showed no plaque disruption, showing the role of OCT in understanding the pathophysiology of STEMI and providing some ideas for the mechanism of this seizure-induced STEMI.
