BACKGROUND: Contrast-induced acute kidney injury (CI-AKI) was traditionally defined as an increase in serum creatinine (sCr) after contrast media exposure. Recently, serum cystatin C (sCyC) has been proposed as an alternative to detect acute changes in renal function. The clinical implications of combining sCyC and sCr to diagnose CI-AKI remain unknown. METHODS AND RESULTS: One thousand seventy-one consecutive patients undergoing coronary angiography/intervention were prospectively enrolled...

BACKGROUND: Most evidence of target-organ damage in hypertension (HTN) is related to the kidneys and heart. Cerebrovascular and cognitive impairment are less well studied. Therefore, this study analyzed changes in cognitive function in patients with different stages of hypertension compared to nonhypertensive controls. METHODS AND RESULTS: In a cross-sectional study, 221 (71 normotensive and 150 hypertensive) patients were compared. Patients with hypertension were divided into 2 stages according to blood pressure (BP) levels or medication use (HTN-1: BP, 140-159/90-99 or use of 1 or 2 antihypertensive drugs; HTN-2: BP, ≥160/100 or use of ≥3 drugs)...

BACKGROUND: Emergent myocardial reperfusion via primary percutaneous coronary intervention is optimal care for patients presenting with ST-segment elevation myocardial infarction (STEMI). Delays in such interventions are associated with increases in mortality. With the shift in focus to contact-to-device (C2D) time as a new perfusion metric, this study was designed to examine how sex affects C2D time and mortality in STEMI patients. METHODS AND RESULTS: Clinical data on male and female STEMI patients were extracted and analyzed from the National Cardiovascular Data Registry from July 1, 2008 to December 31, 2014...

BACKGROUND: High-potency statins reduce cardiovascular events after acute coronary syndromes but remain underused in clinical practice. We examined predictors of nonuse of high-potency statins after acute coronary syndromes. METHODS AND RESULTS: The Stabilization of pLaques usIng Darapladib-Thrombolysis in Myocardial Infarction (SOLID-TIMI 52) trial enrolled patients after an acute coronary syndrome in 36 countries between 2009 and 2011. Statin use was strongly encouraged throughout the trial, and statin potency was at the discretion of the treating physician...

BACKGROUND: Relevant clinical studies have been small and have not convincingly demonstrated whether the perioperative initiation of beta-blockers should be considered in patients with diabetes mellitus undergoing noncardiac surgery. METHODS AND RESULTS: In this nationwide propensity score-matched study, we included patients with diabetes mellitus undergoing noncardiac surgery between 2000 and 2011 from Taiwan's National Health Insurance Research Database. Patients were classified as beta-blocker and non-beta-blocker cohorts...

BACKGROUND: Aldosterone may have adverse effects in the myocardium and vasculature. Treatment with an aldosterone antagonist reduces cardiovascular risk in patients with acute myocardial infarction complicated by heart failure (HF) and left ventricular systolic dysfunction. However, most patients with acute coronary syndrome do not have advanced HF. Among such patients, it is unknown whether aldosterone predicts cardiovascular risk. METHODS AND RESULTS: To address this question, we examined data from the dal-OUTCOMES trial that compared the cholesteryl ester transfer protein inhibitor dalcetrapib with placebo, beginning 4 to 12 weeks after an index acute coronary syndrome...

BACKGROUND: Approximately one third of patients with ST-segment elevation myocardial infarction (STEMI) have left ventricular hypertrophy (LVH), which is associated with impaired outcome. However, the causal association between LVH and outcome in STEMI is unknown. We evaluated the association between LVH and: myocardial infarct size, area at risk, myocardial salvage, microvascular obstruction, left ventricular (LV) function (all determined by cardiac magnetic resonance [CMR]), and all-cause mortality and readmission for heart failure in STEMI patients treated with primary percutaneous coronary intervention...

BACKGROUND: Aortic stiffness impairs optimal ventricular-vascular coupling and left ventricular systolic function, particularly in the long axis. Left ventricular global longitudinal strain (GLS) has recently emerged as a sensitive measure of early cardiac dysfunction. In this study, we investigated the relation between aortic stiffness and GLS in a large community-based sample. METHODS AND RESULTS: In 2495 participants (age 39-90 years, 57% women) of the Framingham Offspring and Omni cohorts, free of cardiovascular disease, we performed tonometry to measure arterial hemodynamics and echocardiography to assess cardiac function...

BACKGROUND: The scientific evidence base in support of population-wide salt reduction is strong, but current high-quality data about salt intake levels in India are mostly absent. This project sought to estimate daily salt consumption levels in selected communities of Delhi and Haryana in north India and Andhra Pradesh in south India. METHODS AND RESULTS: In this study, 24-hour urine samples were collected using an age- and sex-stratified sampling strategy in rural, urban, and slum areas...

BACKGROUND: Macrophages and Wnt proteins (Wnts) are independently involved in cardiac development, response to cardiac injury, and repair. However, the role of macrophage-derived Wnts in the healing and repair of myocardial infarction (MI) is unknown. We sought to determine the role of macrophage Wnts in infarct repair. METHODS AND RESULTS: We show that the Wnt pathway is activated after MI in mice. Furthermore, we demonstrate that isolated infarct macrophages express distinct Wnt pathway components and are a source of noncanonical Wnts after MI...

BACKGROUND: Disrupted atherosclerotic plaques in the left anterior descending coronary artery are discussed controversially as a potential pathophysiological mechanism in Takotsubo syndrome (TTS). Therefore, the aim of the present study was to assess plaque burden and morphology by using optical coherence tomography in patients with TTS. METHODS AND RESULTS: A total of 23 consecutive TTS patients were included in this single-center study and underwent optical coherence tomography imaging of the left main coronary artery and the left anterior descending coronary artery at acute presentation...

BACKGROUND: Considerable controversy exists on the association between retinal vein occlusion (RVO) and stroke risk. Therefore, we conducted a meta-analysis to assess the relationship between RVO and stroke risk. METHODS AND RESULTS: PubMed, EMBASE, and the Cochrane library databases were searched for cohort studies with data on RVO and stroke risk. Studies that reported adjusted relative risks (RRs) with 95% CIs of stroke associated with RVO were included. Stratified analyses were conducted according to key characteristics...

BACKGROUND: Atherosclerosis is a chronic disease that is closely related to inflammation and macrophage apoptosis, which leads to secondary necrosis and proinflammatory responses in advanced lesions. Caspase-activated DNase (CAD) is a double-strand specific endonuclease that leads to the subsequent degradation of chromosome DNA during apoptosis. However, whether CAD is involved in the progression of atherosclerosis remains elusive. METHODS AND RESULTS: CAD(-/-)ApoE(-/-) and ApoE(-/-) littermates were fed a high-fat diet for 28 weeks to develop atherosclerosis...

BACKGROUND: A "Christmas holiday effect" showing elevated cardiovascular mortality over the Christmas holidays (December 25 to January 7) was demonstrated previously in study from the United States. To separate the effect of seasonality from any holiday effect, a matching analysis was conducted for New Zealand, where the Christmas holiday period falls within the summer season. METHODS AND RESULTS: New Zealand mortality data for a 25-year period (1988-2013) was analyzed based on the same methodology used in the previous study...

BACKGROUND: Coronary microcirculatory dysfunction portends a poor cardiovascular outcome. Invasive assessment of microcirculatory dysfunction by coronary flow reserve (CFR) and hyperemic microvascular resistance (HMR) is affected by coronary artery disease (CAD). In this study we propose minimal microvascular resistance (mMR) as a new measure of microcirculatory dysfunction and aim to determine whether mMR is influenced by CAD. METHODS AND RESULTS: We obtained 482 simultaneous measurements of intracoronary Doppler flow velocity and pressure...
