Systemic fibrinogen and neopterin are related to inflammation. We investigated the prognostic utility and possible interactions of these biomarkers in stable coronary artery disease (SCAD) patients undergoing coronary angiography. We included 3,545 patients with suspected stable angina with a median follow-up of 7.3 and 10.2 years for incident acute myocardial infarction (AMI) and all-cause mortality, respectively. Prospective associations were explored by Cox regression. Potential effect modifications were investigated according to strata of fibrinogen, neopterin or high-sensitivity troponin T (hsTnT) below and above the median, as well as gender and smoking habits...

An elderly male patient with coronary heart disease underwent coronary angiography, which revealed bilateral severe coronary artery stenosis. Four stents were implanted, and at 5 h post-surgery, typical hemorrhagic shock appeared. Echocardiography verified heavy bleeding in the right thoracic cavity. Emergency angiography excluded injury or perforation of the coronary artery, aorta, right subclavian artery and brachiocephalic artery. Considering the patient's history of chronic obstructive pulmonary disease and severe cough during the operation, it was suspected that hemothorax was induced by a blood vessel rupture in the pleura...

The percutaneous transradial artery approach for coronary angiography and intervention has been recognized as a safe and effective method, however, it is limited for endovascular therapy (EVT) for femoro-popliteal artery because of lack of devices with longer shaft. Herein, we report two EVT cases for superficial femoral artery disease treated with a long shaft balloon through the radial artery. Although femoro-popliteal artery intervention with this approach has several limits for available devices and technical issues, it is effective for particular patients who are impossible in EVT with femoral artery approach...

REVIEW
Sanjiv Gupta, Madan Mohan Gupta
Takotsubo syndrome is a reversible acute heart failure frequently precipitated by an emotional or physical stress. The clinical presentation resembles acute coronary syndrome. Pathogenesis is complex and may involve brain-heart axis and neuro-hormonal stunning of the myocardium. Coronary angiography reveals normal epicardial arteries with no obstruction or spasm. NT-ProBNP maybe remarkably elevated. Regional wall motion akinesia (RWMA) of left ventricle extends beyond the territory of one coronary artery. Reduced left ventricle ejection fraction (LVEF) and RWMA recover in 6-12 weeks...

Takotsubo syndrome is a rare clinical condition, with a pathophysiology that is not fully understood. Characterised by an acute and usually reversible heart failure, the condition is often preceded by a stressful event. For the diagnosis of Takotsubo syndrome to be possible, the absence of coronary artery disease as a cause is required. We report a case of Takotsubo syndrome in a 47-year-old woman of fertile age. Electrical and echocardiographic presentations were classical in the patient. However, abnormally elevated cardiac biomarkers were registered...

BACKGROUND: The prevalence of coronary artery disease is on the rise as the life expectancy of the population increases. However, treatment of acute coronary syndrome in the elderly patients has its own problems that have not been thoroughly addressed in the clinical trials. Since these patients are generally fragile and have multiple co-morbidities, the course of acute coronary syndrome can frequently be complicated. Infection, which co-exists either at the initial presentation or is acquired during the hospital stay, is a condition about which there is little published data...

OBJECTIVE: The universal definition of myocardial infarction (MI) differentiates MI due to oxygen supply/demand mismatch (type 2) from MI due to plaque rupture (type 1) as well as from myocardial injuries of non-ischaemic or multifactorial nature. The purpose of this study was to investigate how often physicians agree in this classification and what factors lead to agreement or disagreement. METHODS: A total of 1328 patients diagnosed with MI at eight different Swedish hospitals 2011 were included...

There are few data on the utility of physician selection of cardiac tests, including no-test, in a chest pain unit (CPU) to rule out acute coronary syndrome in low-risk patients without a history of coronary artery disease. We analyzed consecutive low-risk patients admitted to our CPU between 2012 and 2014 and determined the proportion of patients selected for testing, the type of initial cardiac test selected, and the incidence of major adverse cardiac events (MACEs) at 30 days and 6 months. The study group comprised 619 patients: mean age 57 years (27 to 92), 332 women (54%), and 360 (58%) with multiple cardiac risk factors...

There are plenty of data on morphology and lumen dimensions of diseased coronary arteries. However, information on normal coronary vessel anatomy is scarce. We provided computed tomography angiography-derived reference values of lumen dimensions in proximal and middle coronary segments in a healthy population with respect to gender and vessel dominance. Consecutive 2,849 computed tomography angiography examinations were reviewed to identify 201 subjects (77 men, patient age 50 ± 13 years) whose coronary arteries were free from any sign of atherosclerosis (calcium score 0, no detectable plaque)...

BACKGROUND: The regional needs and consolidation of cardiac surgery services (CSS) result in an increased number of stand-alone interventional cardiology units. We aimed to explore the impact of a heart team on the decision making and outcomes of patients with multivessel coronary artery disease referred for coronary revascularization in stand-alone interventional cardiology units. METHODS: This prospective study included 1063 consecutive patients with multivessel disease enrolled between January and April 2013 from all 22 hospitals in Israel that perform coronary angiography and percutaneous coronary intervention (PCI), with or without on-site CSS...

BACKGROUND: During transradial (TR) access, it remains unclear whether differences in baseline patients characteristics and hemostasis care impact the rate of radial artery occlusion (RAO). We sought to compare the rate of RAO after TR access with the 6 French(Fr) Glidesheath Slender (GSS6Fr, Terumo, Japan) or a standard 5 Fr sheath in Japanese and non-Japanese patients. METHODS AND RESULTS: The Radial Artery Patency and Bleeding, Efficacy, Adverse evenT (RAP and BEAT) trial randomized 1,836 patients undergoing TR coronary angiography and/or interventions to receive the GSS6Fr or the standard 5 Fr Glidesheath (GS5Fr, Terumo, Japan)...

Percutaneous treatment of chronic total occlusions (CTO) is one of the major challenges in contemporary interventional cardiology. These lesions are identified in 15% to 30% of all patients referred for coronary angiography. Percutaneous coronary intervention (PCI) of CTOs is technically challenging and requires familiarity with advanced interventional techniques as well as specialty equipment. The choice of strategy and materials is based on clinical features and coronary anatomy; the correct choice is essential to improve the success probability...

Transesophageal echocardiography (TEE) is the gold standard imaging study used in the diagnosis of infective endocarditis (IE). Computed tomography angiography (CTA) has undergone rapid advancement as a cardiac imaging technique and has previously shown promise in small non-randomized studies for evaluation of IE. We hypothesized that cardiac CTA would perform similarly to TEE in the detection of endocarditic lesions and that there would be no difference in clinical outcomes whether the coronary arteries were evaluated by CTA or invasive coronary angiography (ICA)...
