Primary percutaneous coronary intervention (pPCI) is associated with improved prognosis in patients with ST-segment elevation myocardial infarction (STEMI). However, no-reflow phenomenon limits the benefit of revascularization and predicts adverse outcomes. The specific mechanism for its occurrence is still not entirely clear, and it is believed at present that platelet activation and inflammation play a pivotal role in developing no-reflow. Both increased mean platelet volume (MPV), which is a platelet activation marker, and lymphopenia, which is an inflammation marker, have been linked to adverse events and poor prognosis after STEMI...

Coronary computed tomography angiography (CCTA)-derived fractional flow reserve from computed tomography (CT-FFR) may provide better diagnostic performance over CCTA alone, but the complexity of its method limits the use in clinical environment. The aim of the present study is to validate a newly developed vessel-length based computational fluid dynamics scheme for the computation of FFR based on CCTA data, compare them with invasively measured FFR, and evaluate its diagnostic performance with that of CCTA...

History of major gastrointestinal (GI) bleeding may represent a frequent clinical indication for left atrial appendage occlusion (LAAO) in patients with non-valvular atrial fibrillation (AF). This study aims to investigate the procedural safety and long-term outcome of patients with previous major GI bleeding (MGIB) who underwent LAAO. Data from the Amplatzer Cardiac Plug multicenter registry on 1,047 patients were analyzed. Patients with previous MGIB as indication for LAAO were compared with patients without previous MGIB...

There are several prognostic risk scores available for patients with heart failure with reduced ejection fraction (HFrEF) that can aid in the decision of listing candidates for heart transplant (HTx). A direct comparison between these scores has not been performed. Therefore, our objective was to evaluate the calibration and discriminative power of 4 contemporary HF scores. A retrospective analysis of 259 patients with HFrEF who underwent cardiopulmonary exercise test was conducted. The Heart Failure Survival Score (HFSS), Seattle Heart Failure Model (SHFM), Meta-analysis Global Group in Chronic Heart Failure (MAGGIC), and Metabolic Exercise Cardiac Kidney Index (MECKI) were compared...

The unique, unphysiological Fontan circulation is associated with an impaired functional status of the patients that is suggested to deteriorate over time. Unfortunately, previous studies did not integrate both pulmonary and cardiac determinants of functional status. In addition, a comparison with the natural decrease in exercise capacity in healthy subjects (in both children and adults) is lacking. This single-center study aims to investigate the functional status in a cohort of Fontan patients in relation to time since Fontan completion and to identify its determinants, including cardiac characteristics and pulmonary characteristics...

Chronic kidney disease frequently accompanies end-stage heart failure and may result in consideration of simultaneous heart and kidney transplantation (SHKT). In recent years, there has been a significant increase in SHKT. This single-center cohort consisted of 35 patients who underwent SHKT during 1996 to 2015. The aim of this study was to review factors that may predict better long-term outcome after SKHT. Thirteen patients (37%) had delayed graft function (DGF) after transplant (defined as the need for dialysis during the first 7 days after transplant), which was significantly associated with mechanical circulatory support device therapy and high right ventricular systolic pressure before transplant...

There have been numerous studies reporting lower mortality rates in obese patients with various cardiovascular disorders than in nonobese patients, a phenomenon known as the "obesity paradox." Limited data exist regarding the effect of obesity on prognosis in patients with pulmonary arterial hypertension (PAH). We used the National Inpatient Sample database for years 2003 to 2011 to identify all patient hospitalizations aged ≥18 years with a primary diagnosis of PAH. Patients with a diagnosis of obesity were identified using Elixhauser co-morbidity measure provided in Nationwide Inpatient Sample database, based on International Classification of Diseases, Ninth Revision, Clinical Modification, codes and the diagnosis-related groups...

Venous thromboembolism (VTE) is a critical complication after surgery. Although pregnancy is a known risk factor of VTE, available data on the risk of postoperative VTE are scarce. Using the American College of Surgeons National Surgical Quality Improvement Program database between 2006 and 2012, we matched 2,582 pregnant women to 103,640 nonpregnant women based on age, race, body mass index, and modified Rogers score. Pregnant women, compared with matched nonpregnant women, experienced higher incidence of VTE (0...

Serum 25-hydroxyvitamin D [25(OH)D] concentration has been identified as a possible modifiable risk factor for cardiovascular disease (CVD). We hypothesized that serum 25(OH)D concentration would be associated with calcifications of the left-sided heart valves, which are markers of CVD risk. Aortic valve calcium (AVC) and mitral annular calcium (MAC) were quantified from cardiac computed tomography scans performed on 5,530 Multi-Ethnic Study of Atherosclerosis participants at the baseline examination (2000 to 2002) and at a follow-up visit at either Examination 2 (2002 to 2004) or Examination 3 (2004 to 2005)...

Brugada syndrome (BrS) is an autosomal dominant channelopathy which is responsible for a large number of sudden cardiac deaths in young subjects without structural abnormalities. The most challenging step in management of patients with BrS is identifying who is at risk for developing malignant ventricular tachyarrhythmia (VTA). In patients with BrS, conduction delay in the right ventricular outflow tract (RVOT) causes a prominent R wave in lead aVR. This electrocardiographic parameter can be useful to detect these high-risk patients...

Ambulatory blood pressure (BP) measurement (ABPM) is recommended to assess optimal BP control, and we studied its influence after an acute type B aortic dissection (ATBAD). We retrospectively collected data from 111 patients with ATBAD from January 2004 to September 2014. Controlled BP group was defined according to a 24-hour BP under 130/80 mm Hg during chronic phase. The population consisted of 85 men, with a mean age of 61 ± 13 years and mean body mass index of 28 ± 6 kg/m(2). The median delay between ambulatory BP measurement and ATBAD was 2 (0...

The aim of this study was to investigate patient outcomes after hospitalization for out-of-hospital cardiac arrest in the United States. We used the 2002 to 2013 Nationwide Inpatient Sample database to identify adults ≥18 years with an International Classification of Diseases, Ninth Revision, Clinical Modification, principal diagnosis code of cardiorespiratory arrest (427.5) or ventricular fibrillation (VF) (427.41). In 4 predefined federal geographic regions: Northeast, Midwest, South, and West, means and proportions of survival, survival stratified by initial rhythm, hospital charges, and cost were estimated...

Vascular complications are common after transcatheter aortic valve replacement (TAVR) and are associated with increased morbidity and mortality. Stent graft implantation enables percutaneous treatment of access site bleeding; however, the efficacy and durability and of this approach are unknown. We studied the immediate outcome of stent graft implantation for control of access site bleeding and the need for repeat vascular interventions after stenting, in a cohort of consecutive patients with severe symptomatic aortic stenosis who underwent transfemoral TAVR...

Racial differences in prevalence and in intervention rate of those with severe aortic stenosis have been reported. Our objective was to evaluate health disparities in referral to cardiothoracic surgery (CTS) for aortic stenosis in black and Hispanic compared with white patients before the transcatheter aortic valve replacement program was started in our community. Using a retrospective cohort design, we identified all patients >40 years, who had been captured with aortic valve disease from January 2011 to June 2016...

In patients with acute decompensated heart failure (HF), the influence of gender on anemia, left ventricular ejection fraction (EF), and outcomes is unclear. We evaluated the association of anemia and left ventricular EF with survival in men or women hospitalized for acute decompensated HF. Of the 4,842 patients enrolled in the Acute Decompensated Heart Failure Syndromes registry, 4,215 patients (2,450 men and 1,765 women) discharged alive after hospitalization for acute decompensated HF were enrolled to evaluate the association of gender, anemia (hemoglobin <13...

We estimated the inpatient resource use for a Fontan patient from birth to adulthood and explored factors that might induce cost differences (2014 US dollar). Inpatient costing records from 4 hospitals with greatest numbers of Fontan patients in Australia and New Zealand were linked with the Fontan registry database. Inpatient records between July 1995 and September 2014 for 420 Fontan patients were linked, and the most frequent primary diagnoses were hypoplastic left heart syndrome (20.7%), tricuspid atresia (19...

Trials of novel therapies for acute heart failure (HF) have followed a convention of short term, most commonly a 48-hour infusion of parenteral therapy compared with placebo or an active drug in a randomized, double-blind study design. Such trials include OPTIME-CHF, SURVIVE, VERITAS, PROTECT, ASCEND-HF, TRUE-HF, and RELAX-AHF-2. This article reviews how this practice in trials began and summarizes the reasons why such a brief exposure of any novel therapy has failed to reduce the end points of rehospitalization or death...

Chronic kidney disease (CKD) is a worldwide growing epidemic associated with an increased risk of cardiovascular morbidity and mortality. Left ventricular (LV) global longitudinal strain (GLS) is a measure of LV systolic function associated with prognosis in the general population. However, little is known about the association between LV GLS and survival in patients with CKD. The aim of the present study was to investigate the prognostic implications of LV GLS in predialysis and dialysis patients specifically...
