Risk Profile and Prognostic Implications of Premature Advanced Coronary Atherosclerotic Disease Among Young to Early Middle-aged Adults: The Coronary Artery Calcium Consortium.

Introduction: Premature advanced subclinical coronary atherosclerosis among young adults is an under-recognized and unique disease phenotype that has not been well characterized.

Methods: We used data from 44,047 participants with no prior CVD history (59.8% male) from the Coronary Artery Calcium (CAC) Consortium.

Gender disparity in morbidity and mortality among patients with ST-elevation myocardial infarction due to spontaneous coronary artery dissection complicated by cardiogenic shock.

Background: There is limited data on gender differences among patients with spontaneous coronary artery dissection (SCAD) who present as ST-elevation myocardial infarction (STEMI) and develop cardiogenic shock (CS).

Objectives: To describe outcomes of SCAD patients presenting with STEMI and CS and outline the differences between men and women.

Methods: We queried the US Nationwide Readmissions Database (NRD) from January 2016 to December 2020 to identify patients with SCAD presenting with STEMI who developed CS.

Coronary Artery Calcium for Risk Stratification of Heart Failure Mortality: The Coronary Artery Calcium Consortium.

Background: There is increasing interest in predicting heart failure (HF), a major cause of morbidity and mortality with a significant financial burden. The role of coronary artery calcium (CAC), an accessible and inexpensive test, in predicting long-term HF mortality among asymptomatic adults remains unknown. We aimed to determine whether CAC burden is associated with HF-related mortality in the CAC Consortium.

Coronary Artery Calcium for Risk Stratification Among Persons With Very High HDL Cholesterol.

Background: Compared to normal high-density lipoprotein (HDL) cholesterol values, very high HDL cholesterol is associated with a higher incidence of mortality and atherosclerotic cardiovascular disease (ASCVD). As such, clinical risk stratification among persons with very high HDL cholesterol is challenging.

Objectives: Among persons with very high HDL cholesterol, the purpose was to determine the prevalence of coronary artery calcium (CAC) and compare the association between traditional risk factors vs CAC for all-cause mortality and ASCVD.

Left Main Coronary Artery Calcium and Diabetes Confer Very-High-Risk Equivalence in Coronary Artery Calcium >1,000.

Background: Although a coronary artery calcium (CAC) of ≥1,000 is a subclinical atherosclerosis threshold to consider combination lipid-lowering therapy, differentiating very high from high atherosclerotic cardiovascular disease (ASCVD) risk in this patient population is not well-defined.

Objectives: Among persons with a CAC of ≥1,000, the authors sought to identify risk factors equating with very high-risk ASCVD mortality rates.

Methods: The authors studied 2,246 asymptomatic patients with a CAC of ≥1,000 from the CAC Consortium without a prior ASCVD event.

Clinical characteristics and statin eligibility of patients under 50 with ST-elevation myocardial infarction.

Aims: This study seeks to understand the clinical characteristics, risk factors, and statin eligibility of younger adults who present with STEMI.

Methods: We performed a retrospective analysis of a prospective cohort of STEMI patients <50 years. Baseline characteristics, medical history, prior medications, drug use, lipid profiles, cardiovascular risk factors were examined.

Outcomes of transforaminal epidural injection of amniotic membrane/umbilical cord particulate for lumbar radiculopathy: a case series.

Background: Radiculopathy can be a debilitating condition. Amniotic membrane/umbilical cord (AM/UC) particulate is a relatively new injectable treatment modality. Herein we report the outcomes of epidural injection of AM/UC particulate in managing lumbar radiculopathy.

The association of lipoprotein(a) and coronary artery calcium in asymptomatic patients: a systematic review and meta-analysis.

Aims: Lipoprotein(a) [Lp(a)] is an atherogenic lipid particle associated with increased risk for coronary heart disease (CHD) events. Coronary artery calcium (CAC) score is a tool to diagnose subclinical atherosclerosis and guide clinical decision-making for primary prevention of CHD. Studies show conflicting results concerning the relationship between Lp(a) and CAC in asymptomatic populations.

Coronary artery calcium and the risk of cardiovascular events and mortality in younger adults: a meta-analysis.

Aims: American College of Cardiology/American Heart Association 2019 prevention guidelines recommend utilizing coronary artery calcium (CAC) to stratify cardiovascular risk in selected cases. However, data regarding CAC and risk in younger adults are less robust due to the lower prevalence of CAC and lower incidence of events. The objective of this meta-analysis is to determine the ability of CAC to predict the risk of cardiovascular events and mortality in adults <50.

Thoracic Aortic Calcium Density and Area in Long-Term Atherosclerotic Cardiovascular Disease Risk Among Men Versus Women.

Background: The development of thoracic aortic calcium (TAC) temporally precedes coronary artery calcium more often in women versus men. Whether TAC density and area confer sex-specific differences in atherosclerotic cardiovascular disease (ASCVD) risk is unknown.

Methods: We studied 5317 primary prevention patients who underwent coronary artery calcium scoring on noncontrast cardiac gated computed tomography with TAC >0.

Effect of routine suction on lung aeration in critically ill neonates and young infants measured with electrical impedance tomography.

Endotracheal suctioning is a widely used procedure to remove secretions from the airways of ventilated patients. Despite its prevalence, regional effects of this maneuver have seldom been studied. In this study, we explore its effects on regional lung aeration in neonates and young infants using electrical impedance tomography (EIT) as part of the large EU-funded multicenter observational study CRADL.

Neonatal high-frequency oscillatory ventilation: where are we now?

High-frequency oscillatory ventilation (HFOV) is an established mode of respiratory support in the neonatal intensive care unit. Large clinical trial data is based on first intention use in preterm infants with acute respiratory distress syndrome. Clinical practice has evolved from this narrow population.

Cardiovascular risk stratification among individuals with obesity: The Coronary Artery Calcium Consortium.

Objective: The effectiveness of coronary artery calcification (CAC) for risk stratification in obesity, in which imaging is often limited because of a reduced signal to noise ratio, has not been well studied.

Methods: Data from 9334 participants (mean age: 53.3 ± 9.

Association of triglyceride levels with adverse cardiovascular events in patients with ST-segment elevation myocardial infarction.

Although there is an established association between elevated triglyceride (eTG, ≥175 mg/dl) levels and adverse cardiovascular events, some studies have suggested that eTG levels may be linked to neutral or even improved clinical outcomes, particularly among patients with acute myocardial infarction. However, these studies had certain limitations, including small sample sizes, heterogeneous study populations, and inadequate statistical adjustments. To address these limitations, we conducted an analysis of 5347 patients with ST-segment elevation myocardial infarction (STEMI) between March 2003 and December 2020, using a prospective registry-based cohort from two large, regional STEMI centers.

Integrated smoking cessation and mood management following acute coronary syndrome: Protocol for the post-acute cardiac event smoking (PACES) trial.

Background: Approximately 400,000 people who smoke cigarettes survive Acute Coronary Syndrome (ACS; unstable angina, ST and non-ST elevation myocardial infarction) each year in the US. Continued smoking following ACS is an independent predictor of mortality. Depressed mood post-ACS is also predictive of mortality, and smokers with depressed mood are less likely to abstain from smoking following an ACS.

Coronary Artery Calcium Dispersion and Cause-Specific Mortality.

Coronary artery calcium (CAC) measures subclinical atherosclerosis and improves risk stratification. CAC characteristics-including vessel(s) involved, number of vessels, volume, and density-have been shown to differentially impact risk. We assessed how dispersion-either the number of calcified vessels or CAC phenotype (diffuse, normal, and concentrated)-impacted cause-specific mortality.

Estimated versus observed 10-year atherosclerotic cardiovascular event rates in a rural population-based health initiative: The Heart of New Ulm Project.

Objective: Assess discrepancy between estimated 10-year atherosclerotic cardiovascular disease (ASCVD) risk and observed 10-year event rates in a rural population participating in cardiovascular health initiative.

Methods: The study included a rural sample of individuals participating in the Heart of New Ulm (HONU), a population-based health initiative aimed at reducing ASCVD risk in a rural community. HONU conducted over 100 baseline screening events with 5221 individuals participating in 2009.

Mortality impact of low CAC density predominantly occurs in early atherosclerosis: explainable ML in the CAC consortium.

Background: Machine learning (ML) models of risk prediction with coronary artery calcium (CAC) and CAC characteristics exhibit high performance, but are not inherently interpretable.

Objectives: To determine the direction and magnitude of impact of CAC characteristics on 10-year all-cause mortality (ACM) with explainable ML.

Methods: We analyzed asymptomatic subjects in the CAC consortium.

Association between hypercholesterolemia and mortality risk among patients referred for cardiac imaging test: Evidence of a "cholesterol paradox?".

Aim: Some observational studies have observed a lower, rather than higher, mortality rate in association with hypercholesterolemia during follow-up of patients after cardiac stress testing. We aim to assess the relationship of hypercholesterolemia and other CAD risk factors to mortality across a wide spectrum of patients referred for various cardiac tests.

Methods And Results: We identified four cardiac cohorts: 64,357 patients undergoing coronary artery calcium (CAC) scanning, 10,814 patients undergoing coronary CT angiography (CCTA), 31,411 patients without known CAD undergoing stress/rest single-photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI), and 5051 patients with known CAD undergoing stress/rest SPECT-MPI.

Discordance Between Coronary Artery Calcium Area and Density Predicts Long-Term Atherosclerotic Cardiovascular Disease Risk.

Background: Coronary artery calcium (CAC) is commonly quantified as the product of 2 generally correlated measures: plaque area and calcium density.

Objectives: The authors sought to determine whether discordance between calcium area and density has long-term prognostic importance in atherosclerotic cardiovascular disease (ASCVD) risk.

Methods: The authors studied 10,373 primary prevention participants from the CAC Consortium with CAC >0.
