Heroin Use Is Associated With Vascular Inflammation in Human Immunodeficiency Virus.

BACKGROUND: Heroin use may work synergistically with human immunodeficiency virus (HIV) infection to cause greater immune dysregulation than either factor alone. Unraveling how this affects end-organ disease is key as it may play a role in the excess mortality seen in people with HIV (PWH) who use heroin despite access to care and antiretroviral therapy. METHODS: This is a prospectively enrolled, cross-sectional study of adults with and without HIV who use and do not use heroin using (18)F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) to compare tissue-specific inflammation including aortic (target-to-background ratio [TBR]), splenic, and bone marrow (standardized uptake value [SUV]). RESULTS: A total of 120 participants were enrolled. The unadjusted mean difference in aortic TBR was 0.43 between HIV-positive [HIV+] heroin+ and HIV+ heroin-negative [heroin-] (P = .02); however, among HIV-, aortic TBR was similar regardless of heroin-use status. Further, HIV-by-heroin-use status interaction was significant (P = .02), indicating that the relationship between heroin use and higher aortic TBR depended on HIV status. On the other hand, both HIV (1.54 vs 1.68; P = .04, unadjusted estimated means for HIV+ vs HIV-) and heroin use were associated with lower bone marrow SUV, although the effect of heroin depended on sex (heroin-use-by-sex interaction, P = .03). HIV-by-heroin-use interaction was not significant for splenic or bone marrow SUV. CONCLUSIONS: Aortic inflammation was greatest in PWH who use heroin, but paradoxically, bone marrow activity was the least in this group, suggesting complex and possibly divergent pathophysiology within these different end organs.

Case series of closure devices complications.

Vascular closure devices (VCD) are effective at achieving hemostasis. VCD failure is attributed to underlying arterial disease, leading to a hazardous situation for obtaining contralateral femoral access. Radial-to-peripheral (R2P) access has emerged as a safe option to rescue these procedural complications. Here, we present two cases of VCD failure rescue utilizing R2P and outline this approach step-by-step.

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.

Proportionate Cardiovascular Mortality in Chronic Inflammatory Disease in Adults in the United States From 1999 to 2019.

BACKGROUND: Despite a rising prevalence of chronic inflammatory disease (CID), the recent trends in cardiovascular disease (CVD) mortality of patients with CID is scarce. In this study, we investigated patterns of CVD mortality in systemic lupus erythematosus (SLE), inflammatory bowel disease (IBD), and rheumatoid arthritis (RA) compared with the general population. METHODS: We used the 1999 to 2019 multiple causes of death files from the national center for health statistics to analyze patterns and trends of proportionate CVD mortality in CID compared with the general population. RESULTS: We analyzed a total of 11,154 CVD deaths in IBD, 58,337 CVD deaths in RA, 6227 CVD deaths in SLE, and 17,826,871 CVD deaths in the general population. Between 1999 and 2019, we found that proportionate CVD mortality decreased significantly in the IBD group (25% to 16%), RA group (34% to 25%), and the general population (41% to 31%), but did not change for the SLE group (15% to 15%). Patients with SLE who died of CVD were approximately 10 years younger compared with CVD decedents with RA, IBD, or general population. The White population had higher proportionate CVD mortality than African American (IBD [19% vs 16%-18%] and SLE [14%-16% vs 12-14%], respectively). CONCLUSIONS: This study identifies current trends in CVD mortality in the CID population and elucidates current demographics in CVD mortality in CID. Although proportionate CVD mortality decreased in the general population, and in patients with RA and IBD, there was no change among patients with SLE. Further studies are needed to elucidate these differences.

The three faces of takotsubo cardiomyopathy in a single patient.

While the classical apical ballooning takotsubo cardiomyopathy (TC) was first reported in the 1990s, the rarer mid-ventricular and basal variants were not formally recognized until recently and they remain poorly understood. In this case report, we describe a 67-year-old woman who, during her hospitalization for a subarachnoid hemorrhage and subsequent readmission, experienced multiple complications, each of which resulted in a different variant of TC. To our knowledge, this is the first report of a single patient developing all three variants of TC.

Contrast-enhanced echocardiographic detection of severe aortic insufficiency in venoarterial extracorporeal membrane oxygenation.

Venoarterial (VA) extracorporeal membrane oxygenation (ECMO) support is an increasingly used temporizing therapy for patients with refractory cardiogenic shock. Contrast-enhanced echocardiography plays a critical role in the diagnosis and management of diseases that precipitate severe cardiac failure. In this case report, we describe a previously healthy 60-year-old woman who presented with dyspnea on exertion, and whose hospital course was complicated by ventricular fibrillation, emergent coronary artery bypass surgery (CABG), and ECMO support. Her contrast-enhanced ECMO images demonstrated a unique pattern of opacification of three of the four cardiac chambers, which led to a diagnosis of severe aortic insufficiency.

Retrospective analysis of ethnic/racial disparities and excess vascular mortality associated with the COVID-19 pandemic.

The Sars coronavirus 2019 (COVID-19) pandemic has resulted in increased morbidity and mortality; however, there is limited understanding of how excess mortality is distributed among different racial and ethnic subgroups and vascular diseases. METHODS: We conducted a retrospective, cross-sectional study design using data from the United States (US) Center for Disease Control (CDC) Wide Ranging Online Data for Epidemiologic Research (Wonder) database. The database contains death certificate information for all US residents by cause of death as ascertained by the treating physician. We examined the trends of excess death by vascular disease specific mortality among different racial and ethnicity subgroups. Excess deaths were defined as the difference between observed numbers of deaths in specific time periods and the expected numbers of deaths in the same time periods. We compared mortality rates during the reference period of 2018-2019 (pre-pandemic) with the study period of 2020-2021 (pandemic years). We also compared excess mortality rates among racial and ethnic subgroups (Non-Hispanic white, Non-Hispanic Black, and Hispanic individuals). Vascular disease was categorized by administrative diagnostic codes (ICD10): Vascular disease (I26, I82, I70-73, I74) and its subtypes Arterial thrombosis (I74), venous thromboembolism (I26, I82) and atherosclerotic disease (I70-73). RESULTS: Compared to 2018-2019, there was a 1.3 % excess mortality associated with vascular disease, a 12.2 % excess mortality due to arterial thrombosis mortality, and an 8.0 % excess mortality due to thromboembolism in 2020-2021. Black individuals demonstrated higher excess vascular mortality (6.9 %) compared to white individuals (-0.3 %) P < .001, higher excess venous thromboembolism mortality (14.1 % vs 5.1 % P = 0.002) and higher atherosclerosis mortality (2.1 % vs -2.6 % P = 0.002). Hispanics compared to white individuals had higher excess vascular mortality (5.1 % vs -0.3 % P = 0.03) and excess venous thromboembolism mortality (24.2 % vs 5.1 % P < 0.001). CONCLUSION: The COVID-19 pandemic has led to a significant and persistent increase in vascular mortality. Excess mortality has disproportionately affected Black and Hispanic individuals compared to white individuals, highlighting the need for further studies to address and eliminate these health care disparities.

Inhalation injury severity and systemic immune perturbations in burned adults.

OBJECTIVE: We aimed to determine whether the severity of inhalation injury evokes an immune response measurable at the systemic level and to further characterize the balance of systemic pro- and anti-inflammation early after burn and inhalation injury. BACKGROUND: Previously, we reported that the pulmonary inflammatory response is enhanced with worse grades of inhalation injury and that those who die of injuries have a blunted pulmonary immune profile compared with survivors. METHODS: From August 2007 to June 2011, bronchoscopy was performed on 80 patients admitted to the burn intensive care unit when smoke inhalation was suspected. Of these, inhalation injury was graded into 1 of 5 categories (0, 1, 2, 3, and 4), with grade 0 being the absence of visible injury and grade 4 corresponding to massive injury. Plasma was collected at the time of bronchoscopy and analyzed for 28 immunomodulating proteins via multiplex bead array or enzyme-linked immunosorbent assay. RESULTS: The concentrations of several plasma immune mediators were increased with worse inhalation injury severity, even after adjusting for age and % total body surface area (TBSA) burn. These included interleukin (IL)-1RA (P = 0.002), IL-6 (P = 0.002), IL-8 (P = 0.026), granulocyte colony-stimulating factor (P = 0.002), and monocyte chemotactic protein 1 (P = 0.007). Differences in plasma immune mediator concentrations in surviving and deceased patients were also identified. Briefly, plasma concentrations of IL-1RA, IL-6, IL-8, IL-15, eotaxin, and monocyte chemotactic protein 1 were higher in deceased patients than in survivors (P < 0.05 for all), whereas IL-4 and IL-7 were lower (P < 0.05). After adjusting for the effects of age, % TBSA burn, and inhalation injury grade, plasma IL-1RA remained significantly associated with mortality (odds ratio, 3.12; 95% confidence interval, 1.03-9.44). Plasma IL-1RA also correlated with % TBSA burn, inhalation injury grade, fluid resuscitation, Baux score, revised Baux score, Denver score, and the Sequential Organ Failure Assessment score. CONCLUSIONS: The severity of smoke inhalation injury has systemically reaching effects, which argue in favor of treating inhalation injury in a graded manner. In addition, several plasma immune mediators measured early after injury were associated with mortality. Of these, IL-1RA seemed to have the strongest correlation with injury severity and outcomes measures, which may explain the blunted pulmonary immune response we previously found in nonsurvivors.

An Interventional Odyssey: The Importance of Planning and Prompt Recognition and Treatment of Complications During a Complex Chronic Total Occlusion Intervention.

Despite significant progress, chronic total occlusion (CTO) percutaneous coronary interventions (PCI) are often challenging and carry increased risk of complications. We present a highly complex CTO PCI case that was successfully completed despite numerous complications (perforation, donor vessel closure, stent loss, guide extension tip fracture, access site bleeding and cardiac arrest) to highlight the importance of appropriate patient selection, pre-procedural planning, comprehensive patient-centered risk/benefit discussion, and prompt recognition and treatment of intra-procedural complications.

Ruptured mycotic coronary artery aneurysm.

Aneurysms complicated by rupture of the coronary arteries are exceedingly rare. Literature regarding management of mycotic aneurysms resulting in rupture is limited. Therefore, we describe a fascinating diagnosis, imaging progression and management of a ruptured mycotic coronary artery aneurysm.

Food insecurity and atherosclerotic cardiovascular disease risk in adults with diabetes.

OBJECTIVES: Adults with diabetes are at an increased risk of atherosclerotic cardiovascular disease (ASCVD), and food insecurity may be a major and underappreciated risk compounder in this population. We sought to analyze the prevalence of food insecurity and its association with ASCVD in adults with diabetes. METHODS: A total of 6424 participants with diabetes were included from the 2019 and 2020 National Health Interview Survey. Food insecurity was determined with a 10-question U.S. Adult Food Security Survey Module, and classified as high, marginal, low, and very low. ASCVD was defined as a self-reported history of coronary artery disease, myocardial infarction, or stroke. RESULTS: Of the 6424 included participants (weighted: n = 21 690 217), 5 405 543 (24.4%) reported a history of ASCVD and 2 946 061 (13.3%) were identified as food insecure (low or very low food security). Adults with food insecurity were more likely to have ASCVD than adults who were food secure (28.9% vs 23.7%; P = 0.008). In the multivariate analyses adjusted for traditional cardiovascular risk factors, all levels of food insecurity were associated with ASCVD compared with food-secure adults (marginal security: odds ratio [OR]: 1.60; 95% confidence interval [CI], 1.18-2.18]; P = 0.003; low security: OR: 2.09; 95% CI, 1.58-2.74]; P < 0.001; very low security: OR: 1.69; 95% CI, 1.22-2.34]; P = 0.001). The association persisted when adjusted for income, location, education, and insurance status. In adults with diabetes and ASCVD, income was a negative factor for food insecurity (OR: 0.71; 95% CI, 0.62-0.80; P < 0.001), but female sex and smoking were positive factors (OR: 1.90; 95% CI, 1.29-2.80; P = 0.001; and OR: 1.97; 95% CI, 1.23-3.18; P = 0.005; respectively). At younger ages, the prevalence of food insecurity increased, especially in adults with ASCVD. CONCLUSIONS: We showed that 13% of U.S. adults with diabetes are food insecure, which was associated with ASCVD independent of traditional and socioeconomic risk factors. Our findings emphasize the importance of recognizing food insecurity as a driver of ASCVD in adults with diabetes, and encourage future efforts at reducing this disparity.

Geographical Patterns and Risk Factor Association of Cardio-Oncology Mortality in the United States.

Cardio-oncology mortality (COM) is a complex issue that is compounded by multiple factors that transcend a depth of socioeconomic, demographic, and environmental exposures. Although metrics and indexes of vulnerability have been associated with COM, advanced methods are required to account for the intricate intertwining of associations. This cross-sectional study utilized a novel approach that combined machine learning and epidemiology to identify high-risk sociodemographic and environmental factors linked to COM in United States counties. The study consisted of 987,009 decedents from 2,717 counties, and the Classification and Regression Trees model identified 9 county socio-environmental clusters that were closely associated with COM, with a 64.1% relative increase across the spectrum. The most important variables that emerged from this study were teen birth, pre-1960 housing (lead paint indicator), area deprivation index, median household income, number of hospitals, and exposure to particulate matter air pollution. In conclusion, this study provides novel insights into the socio-environmental drivers of COM and highlights the importance of utilizing machine learning approaches to identify high-risk populations and inform targeted interventions for reducing disparities in COM.

Myocardial Injury and the Risk of Stroke in Patients With Chronic Kidney Disease (From the Chronic Renal Insufficiency Cohort Study).

Patients with chronic kidney disease (CKD) are at increased risk for stroke. High-sensitivity troponin (hsTP), a marker of myocardial injury, has been associated with stroke risk in patients without CKD, but whether this applies to patients with CKD is not known. We assessed whether hsTP levels is associated with incident stroke in patients with mild-to-moderate CKD without a history of stroke enrolled in the Chronic Renal Insufficiency Cohort. Patients were followed for incident stroke, and the association with hsTP was assessed. A total of 3477 patients without prior stroke were included in this investigation. Over a median follow-up of 7.3 years, 101 (2.8%) patients had an incident stroke. Baseline hsTP was associated with a 9-year risk of stroke (quartile 1: 1.8%, quartile 2: 3.8%, quartile 3: 4.9%, quartile 4: 7.3%; P < .001). After adjusting for traditional stroke risk factors, patients in the fourth quartile (hazard ratio: 2.52, 95% CI: 1.10-5.76, P = .021) had higher risk of stroke when compared with the lowest quartile of hsTP. In conclusion, hsTP levels are associated with increased risk of incident stroke in patients with mild to moderate CKD, and this association remains significant despite the adjustment for traditional risk factors and CKD.

Inflammatory Markers and Risk of Heart Failure With Reduced to Preserved Ejection Fraction.

Chronic systemic inflammation is associated with an increased risk of heart failure (HF). We sought to determine the association between biomarkers of systemic inflammation interleukin (IL)-6, IL-2, tumor necrosis factor alpha (TNF-α), and C-reactive protein (CRP) with those of HF and its subtypes. We hypothesize that inflammatory biomarkers IL-6, IL-2, TNF-α, and CRP are associated with HF and its subtypes. We included participants from the Multi-Ethnic Study of Atherosclerosis (a prospective population-based cohort study [2000 to 2002]), without a history of HF, and with available baseline inflammatory biomarkers. We explored the association of IL-6, IL-2, TNF-α, and CRP with incident HF, HF with reduced ejection fraction (left ventricular ejection fraction [LVEF] <40%, HFrEF), HF with midrange EF (LVEF 40% to 50%, HFmrEF), and HF with preserved ejection fraction (LVEF >50%, HFpEF). Among 6,814 participants, 195 developed HF over 10.9 years (56 HFrEF, 30 HFmrEF, and 57 HFpEF). In the models adjusted for clinical risk factors of HF, IL-6 (hazard ratio [HR] 1.33 per doubling; 95% confidence interval [CI] 1.10 to 1.60), TNF-α (HR 2.49 per doubling; 95% CI 1.18 to 5.28), and CRP (HR 1.18 per doubling; 95% CI 1.06 to 1.30) were associated with all HF, and IL-6 (HR 1.51 per doubling; 95% CI 1.09 to 2.10) and CRP (HR 1.21 per doubling; 95% CI: 1.01 to 1.45) were associated with incident HFpEF, whereas none of the examined biomarkers were associated with HFmrEF or HFrEF. In conclusion, inflammatory biomarkers (IL-6, TNF-α, and CRP) are independently associated with incident HF. IL-6 and CRP are associated with incident HFpEF but not HFrEF or HFmrEF. These findings suggest that activation of the IL-6/CRP pathway (as cause, consequence, or epiphenomenon) may be unique to HFpEF.

Myeloperoxidase is Independently Associated with Incident Heart Failure in Patients with Coronary Artery Disease and Kidney Disease.

Chronic kidney disease (CKD) is associated with high cardiovascular risk and mortality. Myeloperoxidase (MPO) has been linked to adverse events in patients with mild-moderate CKD. We sought to investigate whether MPO levels are associated with adverse outcomes in patients with CKD. We studied participants with mild to moderate CKD in the prospective chronic renal insufficiency cohort (CRIC). We followed patients for incident heart failure (HF), death, and composite outcome (myocardial infarction, incident peripheral arterial disease, cerebrovascular accident and death). A total of 3872 patients were included (2702 without CVD, 1170 with CVD). After multiple adjustments, doubling of MPO in patients with prior CAD was associated with risk of HF (HR 1.15 [1.01-1.30], P = 0.032) and mortality (HR 1.16 [1.05-1.30], P = 0.005), and composite outcome of MI, PAD, CVA and death (HR 1.12 [1.01-1.25], P = 0.031). In this cohort of patients with mild to moderate CKD and CAD, MPO levels are independently associated with incident HF, all-cause mortality, and a composite outcome.

Inflammation-mediated vitamin K and vitamin D effects on vascular calcifications in people with HIV on active antiretroviral therapy.

BACKGROUND: People with HIV (PWH) experience increased systemic inflammation and monocyte activation, leading to increased risk of cardiovascular events (death, stroke, and myocardial infarction) and higher coronary artery calcium scores (CACs). Vitamins D and K2 have significant anti-inflammatory effects; in addition, vitamin K2 is involved in preventing vascular calcifications in the general population. The roles of vitamins D and K in increased coronary calcifications in successfully treated PWH is less understood. METHODS: We prospectively recruited 237 PWH on antiretroviral treatment (ART) and 67 healthy controls. CACs were derived from noncontrast chest computed tomography (CT) and levels of 25-hydroxyvitamin D (vitamin D) and inactive vitamin K-dependent dephosphorylated-uncarboxylated matrix Gla protein (dp-uc MGP, marker of vitamin K deficiency) were measured in plasma during a fasting state. The relationship between inflammation markers, dp-uc MGP, and vitamin D on CACs were estimated using zero-inflated negative binomial regression. Adjusted models included 25(OH)D, MGP, sex, race, age, and markers of inflammation or monocyte activation. RESULTS: Overall, controls had lower median age (45.8 vs. 48.8; P = 0.03), a larger proportion of female individuals (55.2 vs. 23.6%; P < 0.0001), and nonwhite (33.8 vs. 70%; P < 0.0001). Among PWH, less than 1% had detectable viral load and the median CD4+ cell count was 682 (IQR: 473.00-899.00). 62.17% of the participants had zero CACs and 51.32% were vitamin D-deficient (<20 ng/ml). There was no difference in detectable CACs (P = 0.19) or dp-uc MGP (P = 0.42) between PWH and controls. In adjusted models, PWH with nonzero CACs have three times greater expected CAC burden compared with controls. Every 1% increase in MGP (worse K status) decreases the probability of having CACs equal to zero by 21.33% (P = 0.01). Evidence suggests that the effects of 25(OH)D and MGP are inflammation-mediated, specifically through sVCAM, TNF-αRI, and TNF-αRII. CONCLUSION: Vitamin K deficiency is a modifiable preventive factor against coronary calcification in PWH. Further research should determine whether vitamin K supplementation would reduce systemic inflammation, vascular calcification, and risk of cardiovascular events in PWH.
