A 60-year-old man with no coronary artery history and a normal resting electrocardiogram came to the hospital with his second stroke and underwent a treadmill exercise test before carotid endarterectomy. He had no chest pain and stopped because of leg pain. Five minutes after exercise he developed terminal T-wave inversion in leads V3 and V4 that lasted 7 minutes. The T-wave pattern resembled the Wellens pattern that has usually been seen after intense preinfarction rest pain and has usually lasted hours, days, or even weeks...

Advanced chronic kidney disease (CKD) is an independent predictor of mortality in patients undergoing transcatheter aortic valve implantation (TAVI). We aimed to identify predictors of 1-year mortality in patients after TAVI stratified by the presence or absence of advanced CKD (defined as estimated glomerular filtration rate ≤30 ml/min/1.73 m(2) or permanent renal replacement therapy). Patients (n = 1204) from 10 centers in Europe, Japan, and Israel were included: 464 with and 740 without advanced CKD...

Citation classics have been published in many fields of medicine; however, none have focused on interventional cardiology. The goal of this study was to identify the top 100 articles in the field of interventional cardiology and highlight their important trends and characteristics. The Scopus database was used by 2 independent reviewers to extract the top 100 articles using a variety of keywords. We found articles published between 1953 and 2012. Majority (n = 78) of the top 100 articles were published between 1996 and 2010, and the United States was affiliated with the highest number of articles in our list (n = 68)...

Immune light-chain (AL) amyloidosis with cardiac involvement is associated with a high mortality despite improved therapeutic regimens, but there are few reports on prognostic predictors and chronological changes in cardiac morphology and function. Prognosis and its predictors were evaluated in 36 consecutive patients with cardiac AL amyloidosis. Chronological changes in cardiac morphology and function were also evaluated. The median follow-up period was 0.95 years. The median survival time and the 3-year death-free rate after diagnosis in all-cause and cardiac deaths were 0...

Cholesterol crystals (CCs) have been associated with plaque rupture through mechanical injury and inflammation. This study evaluated the presence of CCs during acute myocardial infarction (AMI) and associated myocardial injury, inflammation, and arterial blood flow before and after percutaneous coronary intervention. Patients presenting with AMI (n = 286) had aspiration of culprit coronary artery obstruction. Aspirates were evaluated for crystal content, size, composition, and morphology by scanning electron microscopy, crystallography, and infrared spectroscopy...

Ticagrelor and prasugrel were found to be superior to clopidogrel for the treatment of acute coronary syndrome (ACS) after percutaneous coronary intervention (PCI); however, the comparative effectiveness of these 2 drugs remains unknown. We compared postdischarge outcomes among older patients treated with ticagrelor versus prasugrel after PCI for ACS. We linked clinical data from PCIs performed in older patients (age ≥65) for ACS at 47 Michigan hospitals to Medicare fee-for-service claims from January 1, 2013, to December 31, 2014, to ascertain rates of 90-day readmission and long-term mortality...

Although cardiovascular disease (CVD) and diabetes mellitus are largely lifestyle driven, lifestyle metrics are not used in clinical practice. This study examined the relevance of using a simple lifestyle risk score designed for primary care medicine by testing its ability to predict biological CVD risk factors in a cohort of 3,712 individuals involved in a workplace health evaluation or management program ("Grand Défi Entreprise" project). Using a lifestyle risk score based on waist circumference, fitness, nutritional quality, and physical activity level, employees were categorized into 3 distinct estimated lifestyle risk levels (low, intermediate, and high)...

The prevalence of atrial fibrillation (AF) is increasing in the United States as the population ages, but national surveillance is lacking. This cross-sectional study (2006 to 2014) analyzed data from the Healthcare Cost and Utilization Project's Nationwide Emergency Department Sample, the National (Nationwide) Inpatient Sample, and the National Vital Statistics System. Event totals were estimated independently for emergency department (ED) visits, hospitalizations, and mortality, and then collectively after applying criteria to identify mutually exclusive events...

We compared the incidence of left ventricular systolic dysfunction (LVSD) among patients with left bundle branch block (LBBB) to a matched cohort of patients with a narrow QRS duration <120 ms (NQRS). We hypothesized patients with preserved ejection fraction (EF) ≥50% and LBBB would have higher incidence of LVSD compared with a matched population of NQRS patients. Patients with LBBB on electrocardiogram within 30 days of a baseline echocardiogram with EF ≥50%, who had at least 1 follow-up echocardiogram ≥6 months later, were matched 1:1 on risk factors for cardiomyopathy to patients with NQRS...

Malnutrition has been associated with an increased risk of morbidity and mortality in patients who undergo cardiac surgery. However, many measurements of malnutrition have been inadequate prognostic markers. In this study, we sought to determine whether low preoperative serum prealbumin level was associated with morbidity and mortality in patients who underwent continuous-flow left ventricular assist device (CF-LVAD) implantation. From November 2003 to March 2016, 526 patients with chronic heart failure underwent implantation of a CF-LVAD (HeartMate II, n = 403; HeartWare HVAD, n = 123)...

Values for level- (apical, mid, and basal) and layer-based (endocardial, mid-myocardial, and epicardial) left ventricular (LV) longitudinal strain across age are scarce. The present study evaluates the effect of aging on level- and layer-specific LV longitudinal strain in subjects without structural heart disease. A total of 408 subjects (mean age 58 years [range 16 to 91]; 49% men) were evaluated retrospectively. Subjects were divided into equal groups based on age and gender. Subjects with evidence of structural heart disease or arrhythmias were excluded...

Supraventricular tachyarrhythmia (SVT), especially atrial fibrillation (AF), has been observed in patients with inherited cardiac arrhythmia (ICA). Data on the time course of SVT and the occurrence of SVT other than AF is limited. In this study, we examined the prevalence, co-existence, and the time course of different types of SVT in patients with various ICAs. In this retrospective study, we selected 393 patients (median 49 years, range 17 to 87, 57% male) from a cohort of patients visiting the outpatient clinic for cardiogenetic screening of ICA...

Previous studies have demonstrated that cardiorespiratory fitness is a strong marker of cardiovascular health. Machine learning (ML) can enhance the prediction of outcomes through classification techniques that classify the data into predetermined categories. The aim of the analysis is to compare the prediction of 10 years of all-cause mortality (ACM) using statistical logistic regression (LR) and ML approaches in a cohort of patients who underwent exercise stress testing. We included 34,212 patients (55% males, mean age 54 ± 13 years) free of coronary artery disease or heart failure who underwent exercise treadmill stress testing between 1991 and 2009 and had complete 10-year follow-up...

Recommendations for the management of low-density lipoprotein cholesterol (LDL-C) and the strategy of statin therapy differ between current guidelines. We performed a prospective cohort study using data from the National Health and Nutrition Examination Survey from 1999 to 2010. For all-cause, cardiovascular, and noncardiovascular mortalities, we used Cox proportional hazards models to analyze unadjusted and multivariable-adjusted hazard ratios (HRs). We included age, gender, race and ethnicity, educational attainment, smoking status, body mass index, previous history of cardiovascular disease and cancer, diabetes, hypertension, LDL-C levels, high-density lipoprotein cholesterol levels, log-transferred triglyceride levels, estimated glomerular filtration rate levels, and the presence or absence of macroalbuminuria for the adjustment...

"Early repolarization" (ER) is a frequent finding at standard electrocardiogram (ECG). In this study we assessed whether ER is associated with an increased risk of events, as recently suggested by some studies. We prospectively enrolled 4,176 consecutive subjects without any heart disease who underwent routine ECG recording. ER was diagnosed in case of typical concave ST-segment elevation ≥0.1 mV; a J wave was diagnosed when the QRS showed a notch or a slur in its terminal part. In this study we compared the 6-year outcome of all 687 subjects with ER/J wave and 687 matched subjects without ER/J wave (controls)...

Although both carotid intima-media thickness (cIMT) and carotid plaque score (cPS) determined by carotid ultrasonography reflect the severity of coronary atherosclerosis, there are few reports on direct comparisons of their clinical utilities in patients with familial hypercholesterolemia (FH). We aimed (1) to compare the clinical utilities of these measurements and (2) to estimate the onset and progression of carotid atherosclerosis in patients with FH. We examined 225 patients with FH (126 males; mean age, 51 ± 18 years) who underwent carotid ultrasonography...

Wilson's disease is a well-characterized disorder known to cause liver and brain disease due to abnormal copper deposition. Data regarding copper infiltration of the heart is conflicting, and the risk of heart disease has not been well described. We aimed to determine whether Wilson's disease is associated with cardiac myopathy, clinically evident in the atria as atrial fibrillation (AF) and in the ventricles as heart failure (HF). We longitudinally assessed 14.3 million patients in the California Healthcare Cost and Utilization Project database from 2005 through 2009 for diagnoses of Wilson's disease, AF, HF, and covariates using International Classification of Diseases-9th Edition codes...

Mechanical assist devices have emerged as an established therapeutic option for patients with end-stage heart failure. Because preimplant hypoalbuminemia is a known risk factor for adverse outcomes, we hypothesized that change in albumin may be a prognostic indicator in patients with continuous-flow left ventricular assist devices (cfLVADs). This is a retrospective single-center study of patients who underwent cfLVAD implantation (HeartMate II and HeartWare HVAD) at an academic center from 2008 to 2014. After excluding those who died, were transplanted, or hospitalized during the first 3 months post-implant, albumin values were obtained and stratified by an increase or a decrease from pre-implant to 3 months post-implant on 171 (81% male, mean age 57 ± 16 years) patients (139 for the survival analysis and 90 for the hospitalization analysis)...
