The Cardiovascular Diseases (CVD) are the leading cause of death in the world, being prevention recognized to be a key intervention able to contradict this reality. In this context, although there are several models and scores currently used in clinical practice to assess the risk of a new cardiovascular event, they present some limitations. The goal of this paper is to improve the CVD risk prediction taking into account the current models as well as information extracted from real and recent datasets. This approach is based on a decision tree scheme in order to assure the clinical interpretability of the model...

BACKGROUND: Antiphospholipid antibody syndrome (APS) is a disorder associated with both arterial and venous thromboembolic disease, including acute myocardial infarction (AMI). Given that management with anticoagulants is critical and differs from usual AMI care, identification of key discriminators of patients with AMI with APS is important. METHODS: We performed an English-language systematic review of the literature of cases and case series of patients with AMI and APS from inception until 20 March 2016, collecting demographics, investigations, and outcomes...

BACKGROUND: This study assessed the non-inferiority and safety of regadenoson administration during recovery from inadequate exercise compared with administration without exercise. METHODS: Patients unable to achieve adequate exercise stress were randomized to regadenoson 0.4 mg either during recovery (Ex-Reg) or 1 hour after inadequate exercise (Regadenoson) (MPI1). All patients also underwent non-exercise regadenoson MPI 1-14 days later (MPI2). The number of segments with reversible perfusion defects (RPDs) detected using single photon emission computerized tomography imaging was categorized...

BACKGROUND: Inflammation plays an essential role in the development and complications of atherosclerosis plaques, including acute coronary syndromes (ACS). Indeed, previous reports have shown that within the coronary circulation of ACS patients, several soluble mediators are released. Moreover, it has been demonstrated that endothelial dysfunction might play an important role in atherosclerosis as well as ACS pathophysiology. However, the mechanisms by which these soluble mediators might affect endothelial functions are still largely unknown...

To understand the current impact of diabetes mellitus (DM) on long-term outcomes among patients referred for coronary angiography, we studied 14,337 consecutive patients (5,279 diabetic patients [37%]) referred to coronary angiography for assessment or treatment of coronary artery disease. We investigated long-term all-cause mortality and its interaction with hypoglycemic therapy and presenting coronary status. At baseline, patients with DM had more hypertension, hyperlipidemia, and renal failure; more were women, overweight, and more had previous coronary interventions...

Advances in medical and interventional therapy over the last few decades have revolutionized the treatment of acute myocardial infarction. Despite the ability to restore epicardial coronary artery patency promptly through percutaneous coronary intervention, tissue level damage may continue. The reported 30-day mortality after all acute coronary syndromes is 2 to 3%, and around 5% following myocardial infarction. Post-infarct complications such as heart failure continue to be a major contributor to cardiovascular morbidity and mortality...

BACKGROUND: Thin-cap fibroatheroma (TCFA) is assumed to cause acute coronary syndromes. OBJECTIVE: To compare the accuracy of different models for diagnosing TCFA using parameters derived by CT, validated against optical coherence tomography (OCT). METHODS: One hundred twenty-nine plaques in 106 patients were analyzed using data acquired by 64-row CT with a reconstruction thickness of 0.67 mm and an increment of 0.33 mm. TCFA was defined by OCT as a plaque with lipid content in ≥2 quadrants and the thinnest part of the fibrous cap measuring ≤65 μm...

Low adherence to secondary prevention medications (ATM) of patients after acute coronary syndrome (ACS) is associated with poor clinical outcomes. However, literature provides limited data on assessment of ATM and risks associated with poor in Chinese patients with ACS. In the current work, ATM was assessed in consecutively recruited patients with ACS in Tongji Hospital from November 5, 2013 to December 31, 2014. A total of 2126 patients were classified under low adherence (proportion of days covered (PDC) C< 50%) and high adherence (PDC>50%) groups based on their performance after discharge...
