#1
REVIEW
Jacob S Koruth, Anuradha Lala, Sean Pinney, Vivek Y Reddy, Srinivas R Dukkipati
The clinical use of ivabradine has and continues to evolve along channels that are predicated on its mechanism of action. It selectively inhibits the funny current (If) in sinoatrial nodal tissue, resulting in a decrease in the rate of diastolic depolarization and, consequently, the heart rate, a mechanism that is distinct from those of other negative chronotropic agents. Thus, it has been evaluated and is used in select patients with systolic heart failure and chronic stable angina without clinically significant adverse effects...

BACKGROUND: Some studies have demonstrated that low-density lipoprotein cholesterol (LDL-C) lowering therapy is one of the most important strategies to prevent coronary artery disease. Also, serum triglycerides (TG) and high-density lipoprotein cholesterol (HDL-C) are recognized as independent risk factors of cardiovascular diseases. The aim of this study was to investigate whether the nonfasting TG/HDL-C ratio could affect the incidence of cardiovascular events after percutaneous coronary intervention (PCI) even in patients treated with statins...

Does inflammation matter in coronary artery disease? Is it a driving force in atherosclerosis, or merely an epiphenomenon? And is there space for novel therapies besides those targeting cholesterol? The CANTOS trial, which was presented at the European Society of Cardiology meeting in Barcelona a few weeks ago provides answers to these important questions. Indeed, the results of this trial open up a new avenue for cardiovascular prevention.

BACKGROUND: Patients with obstructive (≥50% stenosis) left main (LM) coronary artery disease (CAD) are at high risk for adverse events; prior studies have also documented worse outcomes among women than men with severe multivessel/LM CAD. However, the prognostic significance of nonobstructive (1%-49% stenosis) LM CAD, including sex-specific differences, has not been previously examined. METHODS AND RESULTS: In the long-term CONFIRM (Coronary CT Angiography Evaluation For Clinical Outcomes: An International Multicenter) registry, patients underwent elective coronary computed tomographic angiography for suspected CAD and were followed for 5 years...

BACKGROUND: Coronary endothelial dysfunction (CED) is an early stage of atherosclerosis and is associated with adverse cardiovascular events. Inflammation may play a role in the development of endothelial dysfunction. To date no study has evaluated the relationship between C-reactive protein and CED. We aimed to determine if C-reactive protein is associated with CED. METHODS: In 1016 patients (mean age 50.7±12.3 years, 34% male) presenting to the catheterization laboratory with chest pain and non-obstructive coronary artery disease, coronary vasoreactivity was assessed by measuring the percent change in coronary blood flow (%ΔCBF) and coronary artery diameter (%ΔCAD) in response to intracoronary acetylcholine...

BACKGROUND: Experimental and clinical data suggest that reducing inflammation without affecting lipid levels may reduce the risk of cardiovascular disease. Yet, the inflammatory hypothesis of atherothrombosis has remained unproved. METHODS: We conducted a randomized, double-blind trial of canakinumab, a therapeutic monoclonal antibody targeting interleukin-1β, involving 10,061 patients with previous myocardial infarction and a high-sensitivity C-reactive protein level of 2 mg or more per liter...

Adipokines are mediators of body composition and are involved in obesity-related complications such as cardiovascular disease. Omega-3 supplementation has not been studied in the setting of body composition and follistatin-like 1 (FSTL1) levels in patients with coronary artery disease (CAD). This study aimed to investigate the effect of omega-3 polyunsaturated fatty acid (ω-3 PUFA) supplementation on body composition indices and serum levels of FSTL1 in CAD patients. A total of 42 male (aged 45-65 years) subjects with angiographically confirmed CAD were included in this randomized, double-blind, placebo-controlled trial study...

REVIEW
Dana K Dawson
Acute stress-induced (takotsubo) cardiomyopathy has a dramatic clinical presentation, mimicking an acute myocardial infarction and is triggered by intense emotional or physical stress. In this paper, we review the current state of knowledge of the mechanistic physiology underlying the left ventricular ballooning. The pathophysiology of the recovery from this acute heart failure syndrome is presented. The short-term and long-term outlook puts this new syndrome on a different perspective compared with recently held views...

BACKGROUND: Cardiac troponin is an independent predictor of cardiovascular mortality in individuals without symptoms or signs of cardiovascular disease. The mechanisms for this association are uncertain, and a role for troponin testing in the prevention of coronary heart disease has yet to be established. OBJECTIVES: This study sought to determine whether troponin concentration could predict coronary events, be modified by statins, and reflect response to therapy in a primary prevention population...

Platelets play a key role in the pathogenesis of acute coronary syndromes and this is why antiplatelet drugs are essential, both in the acute phase and in the long-term follow-up in preventing recurrent myocardial infarction, stroke and cardiovascular death. Aspirin is the most used agent and still remains the first choice drug for lifelong administration in secondary prevention after myocardial infarction. Dual antiplatelet therapy, targeting more than one pathway of platelet activation, has significantly improved the outcome of patients with acute coronary syndromes despite an increased risk of bleeding complications...

BACKGROUND: Spontaneous coronary artery dissection (SCAD) is a nonatherosclerotic but a rare and extremely dangerous clinical entity, it has a high prevalence in young female population with acute myocardial infarction (AMI). The previous reports were restricted to other countries' population, but rare in China. Hence, this study aimed to focus on the characteristics of SCAD as a cause of young female AMI population in Jiangsu, China. METHODS: This study enrolled young female AMI patients aged ≤50 years who underwent coronary angiography (CAG) and intracoronary imaging in our center between January 2013 and December 2016...

BACKGROUND: In patients with ST-segment elevation myocardial infarction (STEMI), the use of percutaneous coronary intervention (PCI) to restore blood flow in an infarct-related coronary artery improves outcomes. The use of PCI in non-infarct-related coronary arteries remains controversial. METHODS: We randomly assigned 885 patients with STEMI and multivessel disease who had undergone primary PCI of an infarct-related coronary artery in a 1:2 ratio to undergo complete revascularization of non-infarct-related coronary arteries guided by fractional flow reserve (FFR) (295 patients) or to undergo no revascularization of non-infarct-related coronary arteries (590 patients)...

BACKGROUND: Body-weight fluctuation is a risk factor for death and coronary events in patients without cardiovascular disease. It is not known whether variability in body weight affects outcomes in patients with coronary artery disease. METHODS: We determined intraindividual fluctuations in body weight from baseline weight and follow-up visits and performed a post hoc analysis of the Treating to New Targets trial, which involved assessment of the efficacy and safety of lowering low-density lipoprotein cholesterol levels with atorvastatin...

Right ventricular (RV) failure remains a major cause of global morbidity and mortality for patients with advanced heart failure, pulmonary hypertension, or acute myocardial infarction and after major cardiac surgery. Over the past 2 decades, percutaneously delivered acute mechanical circulatory support pumps specifically designed to support RV failure have been introduced into clinical practice. RV acute mechanical circulatory support now represents an important step in the management of RV failure and provides an opportunity to rapidly stabilize patients with cardiogenic shock involving the RV...

BACKGROUND: Coronary heart disease is a major cause of heart failure. Availability of risk-prediction models that include both clinical parameters and biomarkers is limited. We aimed to develop such a model for prediction of incident heart failure. METHODS: A multivariable risk-factor model was developed for prediction of first occurrence of heart failure death or hospitalization. A simplified risk score was derived that enabled subjects to be grouped into categories of 5-year risk varying from <5% to >20%...

BACKGROUND: Coronary heart disease (CHD) is the single most common cause of death globally. However, with falling CHD mortality rates, an increasing number of people live with CHD and may need support to manage their symptoms and improve prognosis. Cardiac rehabilitation is a complex multifaceted intervention which aims to improve the health outcomes of people with CHD. Cardiac rehabilitation consists of three core modalities: education, exercise training and psychological support. This is an update of a Cochrane systematic review previously published in 2011, which aims to investigate the specific impact of the educational component of cardiac rehabilitation...

RATIONALE: Higher social integration is associated with lower cardiovascular mortality; however, whether it is associated with incident coronary heart disease (CHD), especially in women, and whether associations differ by case fatality are unclear. OBJECTIVES: This study sought to examine the associations between social integration and risk of incident CHD in a large female prospective cohort. METHODS AND RESULTS: Seventy-six thousand three hundred and sixty-two women in the Nurses' Health Study, free of CHD and stroke at baseline (1992), were followed until 2014...
