    Efficiency of ranolazine in the patient with microvascular angina, atrial fibrillation and migraine.
    Wiad Lek 2016 ;69(6):832-837
    Department of Internal Therapy №1 of Vinnitsa National Pirogov Memorial Medical University, Vinnitsa, Ukraine.
    Microvascular angina (MVA) is rather a common form of stable ischemic coronary disease (CAD) as that such diagnosis is made in 20-30% of patients who previously underwent coronary angiography. The disease occurs three times more frequently in women than in men irrespective of age. Most of these patients are 45-60 years old. Read More

    Suppression of Tumorigenicity 2 in Heart Failure With Preserved Ejection Fraction.
    J Am Heart Assoc 2017 Feb 18;6(2). Epub 2017 Feb 18.
    Mayo Clinic, Rochester, MN
    Background: Soluble suppression of tumorigenicity 2 (sST2) receptor is a biomarker that is elevated in certain systemic inflammatory diseases. Comorbidity-driven microvascular inflammation is postulated to play a key role in heart failure with preserved ejection fraction (HFpEF) pathophysiology, but data on how sST2 relates to clinical characteristics or inflammatory conditions or biomarkers in HFpEF are limited. We sought to determine circulating levels and clinical correlates of sST2 in HFpEF. Read More

    Real-life experience with the specific reversal agent idarucizumab for the management of emergency situations in dabigatran-treated patients: a series of 11 cases.
    J Thromb Thrombolysis 2017 Feb 16. Epub 2017 Feb 16.
    General Hospital Jesenice, Jesenice, Slovenia.
    Non-vitamin K antagonist oral anticoagulants (NOACs) have a favorable benefit-risk profile compared with vitamin K antagonists. However, the lack of specific reversal agents has made the management of some patients receiving long-term treatment with NOACs problematic in emergency situations such as major bleeding events or urgent procedures. Idarucizumab, a fully humanized Fab antibody fragment that binds specifically and with high affinity to dabigatran, was recently approved for use in adult patients treated with dabigatran when rapid reversal of its anticoagulant effect is required.

    Curr Atheroscler Rep 2017 Mar;19(3):13
    McMaster University, Hamilton, ON, Canada.
    Purpose Of Review: Previous research suggests that low-moderate alcohol consumption may have cardioprotective effects, while heavy or binge-pattern drinking is harmful. New evidence and research methodology may inform safe thresholds of alcohol use. This review examines recent evidence regarding alcohol's effect on cardiovascular disease, with a special consideration of pattern, drink type, and total quantity. Read More

    Reversal of Direct Oral Anticoagulants: Current Status and Future Directions.
    Semin Respir Crit Care Med 2017 Feb 16;38(1):40-50. Epub 2017 Feb 16.
    Department of Medicine and Biochemistry and Biomedical Sciences, Thrombosis and Atherosclerosis Research Institute, McMaster University, Hamilton, Ontario, Canada.
    Direct oral anticoagulants (DOACs) are increasingly used for prevention and treatment of venous thromboembolism and for prevention of stroke in patients with nonvalvular atrial fibrillation. In phase III clinical trials that included more than 100,000 patients, the DOACs were at least as effective as vitamin K antagonists (VKAs) and were associated with less serious bleeding, particularly less intracranial bleeding. Real-world evidence supports these outcomes. Read More
