Effects of atherectomy on major adverse limb events for femoropopliteal interventions: Vascular Quality Initiative registry.

Background: Atherectomy use in treatment of femoropopliteal disease has significantly increased despite scant evidence of benefit to long-term clinical outcomes.

Aims: We investigated the clinical benefits of atherectomy over standard treatment for femoropopliteal interventions.

Methods: Using data from the Society of Vascular Surgery's Vascular Quality Initiative (VQI) registry, we identified patients who underwent isolated femoropopliteal interventions for occlusive disease.

Adiposity, aldosterone and plasma renin activity among African Americans: The Jackson Heart Study.

Objective: To analyze associations between adiposity and the renin-angiotensin-aldosterone system (RAAS) in a large African American (AA) cohort.

Methods: Cross-sectional associations of adiposity (body mass index [BMI], waist circumference [WC], waist:height ratio, waist:hip ratio, leptin, adiponectin, leptin:adiponectin ratio [LAR], subcutaneous [SAT] and visceral adipose tissue [VAT], and liver attenuation [LA]) with aldosterone, plasma renin activity (renin), and aldosterone:renin ratio (ARR) were assessed in the Jackson Heart Study using adjusted linear regression models.

Results: A 1-SD higher BMI was associated with a 4.

The role of aldosterone and ideal cardiovascular health in incident cardiovascular disease: The Jackson heart study.

Background: Higher levels of ideal cardiovascular health (ICH) are associated with lower levels of aldosterone and incidence of cardiovascular disease (CVD). However, the degree to which aldosterone mediates the association between ICH and CVD incidence has not been explored. Thus, we investigated the mediational role of aldosterone in the association of 5 components of ICH (cholesterol, body mass index (BMI), physical activity, diet and smoking) with incident CVD and the mediational role of blood pressure (BP) and glucose in the association of aldosterone with incident CVD in a cohort of African Americans (AA).

The role of aldosterone and ideal cardiovascular health in incident diabetes: The Jackson Heart Study.

Background: Greater attainment of ideal cardiovascular health (ICH) and lower serum aldosterone are associated with lower diabetes risk. Higher levels of ICH are associated with lower aldosterone. The mediational role of aldosterone in the association of ICH with incident diabetes remains unexplored.

Impact of Hospital Safety-Net Burden on Outcomes of In-Hospital Cardiac Arrest in the United States.

Unlabelled: High safety-net burden hospitals (HBHs) treating large numbers of uninsured or Medicaid-insured patients have generally been linked to worse clinical outcomes. However, limited data exist on the impact of the hospitals' safety-net burden on in-hospital cardiac arrest (IHCA) outcomes in the United States.

Objectives: To compare the differences in survival to discharge, routine discharge home, and healthcare resource utilization between patients at HBH with those treated at low safety-net burden hospital (LBH).

Associations of Cardiometabolic Multimorbidity With All-Cause and Coronary Heart Disease Mortality Among Black Adults in the Jackson Heart Study.

Importance: A combination of diabetes, coronary heart disease (CHD), and stroke has multiplicative all-cause mortality risk compared with any individual morbidity in White populations, but there is a lack of studies in Black populations in the US.

Objective: To examine the association of cardiometabolic multimorbidity (diabetes, stroke, and CHD) individually and collectively with all-cause and CHD mortality.

Design, Setting, And Participants: This cohort study included Black adults in the Jackson Heart Study followed over a median of 15 years.

Vitamin D, parathyroid hormone, glucose metabolism and incident diabetes in the multiethnic study of atherosclerosis.

Introduction: Higher concentrations of serum 25-hydroxyvitamin D (25(OH)D) and lower concentrations of parathyroid hormone (PTH) are associated with lower insulin resistance and incident diabetes in non-Hispanic White and Hispanic Americans. Results are mixed in other populations, with no observational studies in a large multiethnic cohort. The association of serum 25(OH)D with diabetes may vary by adiposity level.

Glucometabolic State Transitions: The Jackson Heart Study.

Background: Diabetes and prediabetes are common among African Americans (AA), but the frequency and predictors of transition between normal, impaired glucose metabolism, and diabetes are not well-described. The aim of this study was to examine glucometabolic transitions and their association with the development of type 2 diabetes (T2D).

Methods: AA participants of the Jackson Heart Study who attended baseline exam (2000-2004) and at least one of two subsequent exams (2005-2008 and 2009-2013, ~8 years) were classified according to glycemic status.

Intensive care unit hospitalizations and outcomes in patients with severe COVID-19 during summer and fall surges in Georgia.

Background: There is limited data on the difference in the clinical characteristics and outcomes of patients with severe coronavirus disease 2019 (COVID-19) infection in the summer compared to the fall surge.

Aim: To compare the sociodemographic, clinical characteristics, and outcomes among mechanically ventilated patients with severe COVID-19 infection admitted to the intensive care unit (ICU) during the summer and fall surges in the year 2020.

Methods: We included patients admitted to the ICU and treated with invasive mechanical ventilation for COVID-19 associated respiratory failure between April 1 and December 31, 2020.

Intravascular Ultrasound-Guided Catheter-Based Aspiration Thrombectomy in Patients With Acute Submassive Pulmonary Embolism: A Case Series.

Contrast pulmonary angiography by hand injection or power injection is widely used during catheter-based therapies for acute submassive and massive pulmonary embolism (PE). Particularly, in patients with pre-existing chronic kidney disease, this approach may present a prognostic challenge owing to a double-contrast load, initially during computed tomographic pulmonary angiography (CTPA), and during percutaneous treatment. Intravascular ultrasound (IVUS) has been used as an adjunctive imaging modality in the percutaneous treatment of chronic thromboembolic pulmonary hypertension, and in coronary and peripheral vascular interventions.

Association of Serum Aldosterone and Plasma Renin Activity With Ambulatory Blood Pressure in African Americans: The Jackson Heart Study.

Background: The renin-angiotensin-aldosterone system (RAAS) is an important driver of blood pressure (BP), but the association of the RAAS with ambulatory BP (ABP) and ABP monitoring phenotypes among African Americans has not been assessed.

Methods: ABP and ABP monitoring phenotypes were assessed in 912 Jackson Heart Study participants with aldosterone and plasma renin activity (PRA). Multivariable linear and logistic regression analyses were used to analyze the association of aldosterone and PRA with clinic, awake, and asleep systolic BP and diastolic BP (DBP) and ABP monitoring phenotypes, adjusting for important confounders.

Intravascular ultrasound-guided pulmonary artery embolectomy for saddle pulmonary embolism.

A percutaneous catheter-directed treatment approach is preferred among patients with acute submassive pulmonary embolism (PE) and chronic kidney disease (CKD), who are at significant risk of bleeding with thrombolytics. Limiting contrast volume in these patients could reduce morbidity and mortality associated with contrast-induced acute kidney injury (CI-AKI). We present the case of a 61-year-old African American woman (BMI 46.

Factors influencing the uptake of influenza vaccination in African American patients with heart failure: Findings from a large urban public hospital.

Background: Evidence suggests that annual influenza vaccination may prevent acute heart failure exacerbation episodes and improve survival.

Objective: Determine the influenza vaccination rate among African American patients with heart failure and identify predictors of uptake.

Methods: African American patients with heart failure were recruited at Grady Memorial Hospital, Atlanta GA between October 1, 2017 and April 28, 2018 (N = 281).

The association between health care coverage and prevalence of cardiovascular diseases and diabetes over a 10-year period.

Persons without health care coverage have poorer health outcomes. We investigated the association between health care coverage and trends in the prevalence of cardiovascular disease (CVD) and diabetes pre- and post-Affordable Care Act (ACA) periods. Using data from 3,824,678 surveyed adults in the Behavioral Risk Factor Surveillance System survey from 2007 - 2016, we calculated the yearly prevalence of CVD and diabetes.

The Association of Life's Simple 7 with Aldosterone among African Americans in the Jackson Heart Study.

Background: Among African Americans (AAs), attaining higher levels of American Heart Association (AHA) ideal cardiovascular health (Life's Simple 7 [LS7]) is associated with lower risk of diabetes and cardiovascular disease (CVD). We previously showed that aldosterone is associated with higher risk of diabetes and CVD in AAs. Thus, we investigated the association of LS7 metrics with aldosterone in the Jackson Heart Study (JHS).

Glycemic Markers and Subclinical Cardiovascular Disease: The Jackson Heart Study.

Background We investigated the associations of glycemic markers (HbA [hemoglobin A], fasting plasma glucose, and insulin resistance-homeostasis model assessment of insulin resistance) with subclinical cardiovascular disease (CVD) among blacks. Methods We included 4303 community-dwelling blacks (64% women; mean age, 54.5 years) without prevalent CVD.

Ideal cardiovascular health, glycaemic status and incident type 2 diabetes mellitus: the REasons for Geographic and Racial Differences in Stroke (REGARDS) study.

Aims/hypothesis: Ideal cardiovascular health (CVH) is associated with lower diabetes risk. However, it is unclear whether this association is similar across glycaemic levels (normal [<5.6 mmol/l] vs impaired fasting glucose [IFG] [5.

Renin-Angiotensin-Aldosterone System, Glucose Metabolism and Incident Type 2 Diabetes Mellitus: MESA.

Background Mechanistic studies suggest that aldosterone impairs glucose metabolism. We investigated the cross-sectional associations of aldosterone and plasma renin activity with fasting plasma glucose, insulin resistance ( IR ), β-cell function, and longitudinal association with incident diabetes mellitus among adults in MESA (the multiethnic study of atherosclerosis) prospective cohort study. Methods and Results Homeostatic model assessment of IR ( HOMA 2- IR ) and HOMA 2-β were used to estimate IR and β-cell function, respectively.

Comparison of Measures of Adiposity and Cardiovascular Disease Risk Factors Among African American Adults: the Jackson Heart Study.

Obesity, particularly central adiposity, is a well-established risk factor for cardiovascular disease (CVD). Waist circumference (WC) is measured in numerous epidemiologic studies as a relatively simple indicator of central adiposity. However, recently, investigators have considered a measure that takes height into consideration, waist-to-height ratio (WHtR) as a more sensitive predictor of CVD.
