BACKGROUND: Mortality data are affected by miscertification of the medical cause of death deaths and changes to cause of death classification systems. We present both mappings of ICD9 and ICD10 to a unified list of causes, and a new statistical model for reducing the impact of misclassification of cause of death. METHODS: We propose a Bayesian mixed-effects multinomial logistic model that can be run on individual record level death certificates to reclassify "garbage-coded" deaths onto causes that are more meaningful for public health purposes...

BACKGROUND: The Multimorbidity (MM) Index predicts the prognosis of patients from their diagnostic history. In contrast to existing approaches with broad diagnostic categories, it treats each diagnosis as a separate independent variable using individual International Classification of Disease, Revision 9 (ICD-9) codes. OBJECTIVE: This paper describes the MM Index, reviews the published data on its accuracy, and provides procedures for implementing the Index within electronic health record (EHR) systems...

Congestive heart failure (CHF) is a cardiac disease associated with the decreasing capacity of the cardiac output. It has been shown that the CHF is the main cause of the cardiac death around the world. Some works proposed to discriminate CHF subjects from healthy subjects using either electrocardiogram (ECG) or heart rate variability (HRV) from long-term recordings. In this work, we propose an alternative framework to discriminate CHF from healthy subjects by using HRV short-term intervals based on 256 RR continuous samples...

BACKGROUND/METHODS: The aging patient with severe congenital heart disease (CHD) faces many challenges: heart failure, arrhythmia, and in the Fontan patient, liver disease. Our goal was to define combined heart liver transplant (CHLT) and isolated orthotopic heart transplant (OHT) outcomes in U.S. adult CHD patients. The U.S. United Network for Organ Sharing (UNOS) thoracic and liver databases were queried for cardiac and CHD diagnoses, from inception-2014. RESULTS: In CHLT, CHD made up 22% of waitlist patients (non-CHD n=262 vs...

Heart failure (HF) is a growing global health concern that affects more than 20 million people worldwide. With an ever-growing segment of the population over the age of 65, the prevalence of HF and its associated costs are expected to increase exponentially over the next decade. Advances in the understanding of the pathophysiology and treatment of HF have resulted in the ability to enhance both the quantity and the quality of life of patients with HF. This article reviews the current understanding of the pathophysiology, cause, classification, and treatment of HF and describes areas of uncertainty that demand future study...

Heart failure (HF) has high morbidity and mortality in children. This study aimed to investigate the value of cardiac myosin binding protein-C (cMyBP-C) as a diagnostic and prognostic biomarker in children with heart failure. This study was a prospective case-control study that involved 50 children with acute HF and 25 healthy children of matched age and sex as a control group. cMyBP-C plasma levels were measured in patients with HF at the time of admission and 1 month after treatment. Echocardiographic assessment was done for all children...

BACKGROUND: Several studies have shown that, after an acute myocardial infarction, women have worse prognosis than males. However, it is not clear if female sex is an independent predictor of mortality risk. Our aim was to analyse sex influence on the prognosis of these patients. METHODS: Retrospective registry of patients with ST segment elevation myocardial infarction (STEMI) from January 2010 to April 2015. RESULTS: From 1111 patients, 258 (23...

BACKGROUND: The ACC/AHA guidelines introduced a new classification of severe aortic stenosis (AS) mainly based on maximum jet velocity (Vmax) and mean pressure gradient (mPG), but not on aortic valve area (AVA). However, prognostic value of this new classification has not yet been fully evaluated. METHODS AND RESULTS: We studied 1512 patients with asymptomatic severe AS enrolled in the CURRENT AS registry in whom surgery was not initially planned. Patients were divided into 2 groups: Group 1 (N=122) comprised patients who met the recommendation for surgery; high-gradient (HG)-AS (Vmax≥4...

BACKGROUND: The EQ-5D-3L, a generic multi-attribute utility instrument (MAUI), is widely employed to assist in economic evaluations in health care. The EQ-5D-3L lacks sensitivity when used in conditions such as cardiovascular disease (CVD). Although there are number of CVD specific quality of life instruments, currently, there are no CVD specific MAUIs. The aim of this study is to investigate the discriminative ability and responsiveness of the EQ-5D-3L and the Minnesota Living with Heart Failure Questionnaire (MLHF), a CVD specific quality of life instrument in a group of heart failure patients...

BACKGROUND: Hyperhomocysteinemia was found to be uniformly associated with the development of heart failure (HF) and HF mortality; however, it is uncertain whether this relation is causative or not. We used Mendelian randomization to examine the associations of the methylene tetrahydrofolate gene (MTHFR) and paraoxonase 1 gene (PON1) variants as a proxy for lifelong exposure to high Hcy and Hcy-thiolactone concentrations with the development of HF in men aged ≤60years and the occurrence of adverse effects at one-year follow-up...

REVIEW
Marco Guazzi, Valentina Labate
Pulmonary hypertension (PH) due to left heart disease (LHD), i.e., group 2 PH, is the most common reason for increased pressures in the pulmonary circuit. Although recent guidelines incorporate congenital heart disease in this classification, left-sided heart diseases of diastolic and systolic origin including valvular etiology are the vast majority. In these patients, an increased left-sided filling pressure triggers a multistage hemodynamic evolution that ends into right ventricular failure through an initial passive increase in pulmonary artery pressure complicated over time by pulmonary vasoconstriction, endothelial dysfunction, and remodeling of the small-resistance pulmonary arteries...

The new guidelines for the diagnosis and treatment of acute and chronic heart failure (HF) were presented in May 2016 during the congress of the Heart Failure Association (HFA) of the European Society of Cardiology (ESC) in Florence. An important amendment affects the classification of HF which now differentiates between HF with preserved ejection fraction (HFpEF) and left ventricular EF (LVEF) > 50%, HF with reduced ejection fraction (HFrEF, LVEF < 40%) and the new entity HF with mid-range ejection fraction (HFmrEF, LVEF 40-49%)...

INTRODUCTION: Primary hyperparathyroidism (pHPT), most commonly caused by solitary parathyroid adenomas, leads to mobilization of calcium and is known to result in nephrolithiasis and osteoporosis. To date, studies of pHPT and cardiovascular risk factors and events have produced discrepant findings, likely due to small sample sizes and enrolling populations with varying disease severity. HYPOTHESIS: We utilized a national registry, hypothesizing an association between pHPT and cardiovascular risk factors and events...

Risk assessment of congestive heart failure (CHF) is essential for detection, especially helping patients make informed decisions about medications, devices, transplantation, and end-of-life care. The majority of studies have focused on disease detection between CHF patients and normal subjects using short-/long-term heart rate variability (HRV) measures but not much on quantification. We downloaded 116 nominal 24-hour RR interval records from the MIT/BIH database, including 72 normal people and 44 CHF patients...

Heart failure (HF) progression has not been studied in pediatric patients as well as HF in patients with a normal ejection fraction (HFNEF). We aimed to evaluate galactin-3 in children with HFNEF and reduced ejection fraction (HFREF) and its correlation to disease severity and progression. This cross-sectional study involved 45 chronic HF patients taking G1a (23 HFNEF children) and G1b (22 HFREF children) compared to 45 age- and sex-matched controls (G2) subjected to history taking, Ross functional HF classification, conventional and tissue Doppler echocardiographic systolic and diastolic function assessment (FS%, E/A, S m, E m/A m, E/E m) and laboratory investigations [glomerular filtration rate, serum galactin-3 level (ELISA)]...
