Impact of Allopurinol Pretreatment on Coronary Blood Flow and Revascularization Outcomes after Percutaneous Coronary Intervention in Acute STEMI Patients: A Randomized Double Blind Clinical Trial.

Introduction: The generation of reactive oxygen species, which is induced by the activation of the xanthine oxidase (XO) enzymatic system, is one of the primary causes of ischemia-reperfusion injury for an ischemic heart. Allopurinol, as an XO inhibitor, plays an inhibitory role in free radical production in ST-elevation myocardial infarction (STEMI) patients. The aim of this study is to evaluate the impact of allopurinol pre-treatment on post-revascularization outcomes in patients admitted with STEMI.

Severe fetal hemolytic disease due to anti-M alloimmunization: A case report and literature review.

Fetal hemolysis is caused by maternal antibodies that cross the placenta. Anti-M antibodies can rarely cause severe forms of alloimmunization in the fetus and newborn. We present a case of severe anti-M alloimmunization requiring a total of 8 intrauterine transfusions, in a patient with a prior poor obstetrical history.

Right heart failure with left ventricular assist devices: Preoperative, perioperative and postoperative management strategies. A clinical consensus statement of the Heart Failure Association (HFA) of the ESC.

Right heart failure (RHF) following implantation of a left ventricular assist device (LVAD) is a common and potentially serious condition with a wide spectrum of clinical presentations with an unfavourable effect on patient outcomes. Clinical scores that predict the occurrence of right ventricular (RV) failure have included multiple clinical, biochemical, imaging and haemodynamic parameters. However, unless the right ventricle is overtly dysfunctional with end-organ involvement, prediction of RHF post-LVAD implantation is, in most cases, difficult and inaccurate.

Mechanisms of myocardial reverse remodelling and its clinical significance: A scientific statement of the ESC Working Group on Myocardial Function.

Cardiovascular disease (CVD) is the leading cause of morbimortality in Europe and worldwide. CVD imposes a heterogeneous spectrum of cardiac remodelling, depending on the insult nature, that is, pressure or volume overload, ischaemia, arrhythmias, infection, pathogenic gene variant, or cardiotoxicity. Moreover, the progression of CVD-induced remodelling is influenced by sex, age, genetic background and comorbidities, impacting patients' outcomes and prognosis.

Update of the clinical guideline for hypertension diagnosis and treatment in Iran.

Background: This article introduces the updated version of the Iranian guideline for the diagnosis and treatment of hypertension in adults. The initial version of the national guideline was developed in 2011 and updated in 2014. Among the reasons necessitating the update of this guideline were the passage of time, the incompleteness of the scopes, the limitation of the target group, and more important is the request of the ministry of health in Iran.
