BACKGROUND: To describe the long-term mortality of a complete national cohort of acute coronary syndrome (ACS) patients enrolled in 2002, to compare this with a national age, sex and Māori ethnicity matched population, and to assess the influence of baseline factors on the 12-year mortality. METHODS: We reviewed 721 patients with a discharge diagnosis of an ACS who were enrolled in the first New Zealand ACS audit group cohort over 14days in May 2002. We matched the cohort to the national mortality database using each patient's unique national identity number...

BACKGROUND : Efforts to safely reduce length of stay for emergency department patients with symptoms suggestive of acute coronary syndrome (ACS) have had mixed success. Few system-wide efforts affecting multiple hospital emergency departments have ever been evaluated. We evaluated the effectiveness of a nationwide implementation of clinical pathways for potential ACS in disparate hospitals. METHODS : This was a multicenter pragmatic stepped-wedge before-and-after trial in 7 New Zealand acute care hospitals with 31 332 patients investigated for suspected ACS with serial troponin measurements...

BACKGROUND: Arthroplasty implants commonly contain elemental metal that may undergo wear-related release. Recently, cases of hip implant-associated myocardial injury have been reported. However, we are not aware of any previous study that has systematically measured myocardial metal levels or examined the relationship with total hip arthroplasty (THA). METHODS: Archives of our institution were queried for autopsies of individuals who had undergone THA between 1990 and 2013...

ATP-sensitive K(+) (KATP) channels uniquely link cellular energy metabolism to membrane excitability and are expressed in diverse cell types that range from the endocrine pancreas to neurons and smooth, skeletal, and cardiac muscle. A decrease in the surface expression of KATP channels has been linked to various disorders, including dysregulated insulin secretion, abnormal blood pressure, and impaired resistance to cardiac injury. In contrast, up-regulation of KATP channel surface expression may be protective, for example, by mediating the beneficial effect of ischemic preconditioning...

OBJECTIVES: Early discharge of patients with presentations triggering assessment for possible acute coronary syndrome is safe when clinical assessment indicates low-risk, biomarkers are negative, and electrocardiograms (ECGs) are non-ischemic. We hypothesized that the Emergency Department Assessment of Chest Pain Score (EDACS) combined with a single measurement of high-sensitivity cardiac troponin (hs-cTn) could allow early discharge of a clinically meaningful proportion of patients. METHODS: We pooled data from 4 patient cohorts from New Zealand and Australia presenting to an ED with symptoms suggestive of ACS...

Importance: High-sensitivity cardiac troponin I testing is widely used to evaluate patients with suspected acute coronary syndrome. A cardiac troponin concentration of less than 5 ng/L identifies patients at presentation as low risk, but the optimal threshold is uncertain. Objective: To evaluate the performance of a cardiac troponin I threshold of 5 ng/L at presentation as a risk stratification tool in patients with suspected acute coronary syndrome. Data Sources: Systematic search of MEDLINE, EMBASE, Cochrane, and Web of Science databases from January 1, 2006, to March 18, 2017...

BACKGROUND: Children with obesity have hypertrophic cardiac remodeling. Hypertension is common in pediatric obesity, and may independently contribute to hypertrophy. We hypothesized that both the degree of obesity and ambulatory blood pressure (ABP) would independently associate with measures of hypertrophic cardiac remodeling in children. METHODS: Children, aged 8-17 years, prospectively underwent cardiovascular magnetic resonance (CMR) and ABP monitoring. Left ventricular (LV) mass indexed to height(2...

BACKGROUND: Sarcoidosis is believed to represent a genetically primed, abnormal immune response to an antigen exposure or inflammatory trigger, with both genetic and environmental factors playing a role in disease onset and phenotypic expression. In a population of firefighters with post-World Trade Center (WTC) 9/11/2001 (9/11) sarcoidosis, we have a unique opportunity to describe the clinical course of incident sarcoidosis during the 15 years' postexposure and, on average, 8 years following diagnosis...

BACKGROUND: Recently, 2 randomized controlled trials showed that the instantaneous wave-free ratio (iFR), a resting coronary physiological index, is noninferior to fractional flow reserve for guiding revascularization. The resting distal to aortic coronary pressure (Pd/Pa) measured at rest is another adenosine-free index widely available in the cardiac catheterization laboratory; however, little is known about the agreement of Pd/Pa using iFR as a reference standard. OBJECTIVES: The goal of this study was to investigate the agreement of Pd/Pa with iFR...

Fentanyl is a potent opiate commonly administered during cardiac catheterization procedures in North America. The question of whether fentanyl could have adverse consequences in patients undergoing percutaneous coronary intervention (PCI) is raised by recent research demonstrating that intravenous morphine significantly delays the absorption of oral P2Y12 platelet inhibitors. The presumed mechanism is slowed gastric emptying. The single-center Platelet Aggregation with tiCagrelor Inhibition and FentanYl (PACIFY) trial randomized adults undergoing clinically-indicated elective coronary angiography to receive the procedure with or without intravenous fentanyl (NCT02683707)...

Aims: Luma is a recently discovered, evolutionarily conserved protein expressed in mammalian heart that is associated with the LInker of Nucleoskeleton and Cytoskeleton (LINC) complex. The LINC complex structurally integrates the nucleus and the cytoplasm, and plays a critical role in mechanotransduction across the nuclear envelope. Mutations in several LINC components in both humans and mice result in various cardiomyopathies, implying they play essential, non-redundant roles. A single amino acid substitution of serine 358 to leucine (S358L) in LUMA is the unequivocal cause of a distinct form of arrhythmogenic cardiomyopathy...

BACKGROUND AIMS: Light chain (AL) amyloidosis is a protein misfolding disease characterized by extracellular deposition of immunoglobulin light chains (LC) as amyloid fibrils. Patients with LC amyloid involvement of the heart have the worst morbidity and mortality. Current treatments target the plasma cells to reduce further production of amyloid proteins. There is dire need to understand the mechanisms of cardiac tissue damage from amyloid to develop novel therapies. We recently reported that LC soluble and fibrillar species cause apoptosis and inhibit cell growth in human cardiomyocytes...
