Background: It remains controversial whether adding ezetimibe to low/moderate-intensity statins has a more beneficial impact on the treatment efficacy and safety of patients with existing atherosclerotic cardiovascular disease (ASCVD) compared to high-intensity statin regimens.

Hypothesis: A combination of low/moderate-intensity statins plus ezetimibe might be more effective and safer than high-intensity statin monotherapy.

Methods: We searched databases for randomized controlled trials comparing lipid profile alterations, drug-related adverse events, and MACE components between high-intensity statin monotherapy and low/moderate-intensity statin plus ezetimibe combination therapy.

Key Clinical Message: It is important to note that prevention of button battery ingestion is the most effective way to reduce its incidence and complications. This is unachievable without providing educational plans for parents. Moreover, triage nurses and first-line staff who take the history of patients and physicians should take the history to evaluate the risk of battery ingestion.

Background: Patients with -thalassemia major depend on lifelong transfusion, resulting in tissue iron overload. This longitudinal retrospective observational study aims to assess myocardial and liver iron overload using magnetic resonance imaging (MRI) and investigate the lag between myocardial and liver iron unloading in -thalassemia patients undergoing chelation therapy.

Methods: Beta-thalassemia major patients with at least two MRI studies between 2016 and 2020 were enrolled.

Article Synopsis
  • New-onset postoperative atrial fibrillation (POAF) is common after coronary artery bypass grafting (CABG) and can increase stroke risk; this study compares the safety and feasibility of two anticoagulants, Warfarin and Rivaroxaban, in such patients.
  • A randomized trial with 66 patients showed no thrombotic or major bleeding events in either group, although minor bleeding occurred with no significant difference.
  • The findings suggest that both anticoagulants are safe and effective, potentially favoring Rivaroxaban for its convenience in managing POAF after CABG surgery.*

Background: The control of blood pressure (BP) is a challenge in diabetic patients and is associated with adverse outcomes of diabetes. In this systematic review and metaanalysis, we investigated the BP control rate among hypertensive diabetic patients in the Eastern Mediterranean Region (EMR) countries.

Methods: We systematically searched PubMed, Scopus, Embase, Cochrane, and Web of Science databases up to January 2023 for observational studies on BP control among hypertensive diabetic patients in all EMR countries.

Background: Extensive evidence has suggested the cardio-protective properties of the polyphenol curcumin. The aim of this study was to investigate the effects of a highly bioavailable curcumin supplement on cardiometabolic risk factors, health-related quality of life, and depression in patients with coronary slow flow phenomenon (CSFP).

Methods: This randomized double-blind placebo-controlled clinical trial was conducted in 42 patients with CSFP (age 35-70 years, 25 ≤ body mass index < 40 kg/m).

Background: High-intensity statin therapy is currently recommended initial guideline therapy in ACS treatment. However, only a minority of patients are achieving LDL-C attainment goal at 6 months. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are on recommended guideline therapy post-ACS if LDL-C goal attainment is not achieved after high-intensity statin (4-6 weeks) and after the addition of ezetimibe if guideline goal attainment is not achieved after an additional 4-6 weeks.

Background: Transcatheter aortic valve implantation (TAVI) has been increasingly used in patients with severe aortic stenosis (AS). Since coronary artery disease (CAD) is common among these patients, it is crucial to choose the best method and timing of revascularization. This study aims to compare different timing strategies of percutaneous coronary intervention (PCI) in patients with severe AS undergoing TAVI to clarify whether PCI timing affects the patients' outcomes or not.

Key Clinical Message: The history of any allergy to the medications should be asked by physicians before administration of the medication. The coincidence of allergic and ACS symptoms after a short time of drug administration might be an indicator of Kounis syndrome. Allergic and coronary symptoms should be considered and treated.

Increased bleeding tendency is a common and challenging complication of warfarin therapy which results in extensive pharmacogenomic studies in order to develop a personalized dosing approach and minimize the risk of related side effects. Here we aimed to explore the potential role of NQO1 gene expression in warfarin response in a group of Iranian patients. We also evaluated the NQO1 promoter methylation and its association with mRNA expression.

Background: Blunt traumatic aortic injury (BTAI) is the second leading cause of death due to traumas in young patients. The primary presentation might be chest or interscapular pain, difficulty in breathing, and, in severe cases, hypotension. Considering the rapid deterioration of these patients' clinical conditions, prompt diagnosis and treatment initiation are crucial.

Article Synopsis
  • This study assessed how multiarterial grafts (MAG) compare to single arterial grafts (SAG) in terms of all-cause mortality and major adverse events in patients from a Middle Eastern nation.
  • A total of 23,798 patients were analyzed, with findings showing that MAG had lower crude mortality and adverse event rates initially, but these benefits diminished after adjusting for various patient characteristics.
  • The results suggest that while MAG did not improve outcomes for the overall patient population, certain subgroups like younger males and those without risk factors may benefit, warranting further investigation through clinical trials.

Article Synopsis
  • - The study aimed to investigate how sleep duration impacts the risk of developing hypertension (HTN), as previous evidence has been inconsistent about this relationship.
  • - A meta-analysis of 16 cohort studies (involving over 1 million participants) found that short sleep durations are linked to an increased risk of HTN, with more significant risk observed in those sleeping less than 5 hours, and females being more affected than males.
  • - The findings suggest that while short sleep increases the risk of HTN, long sleep does not, indicating a need for targeted prevention strategies for those with insufficient sleep.

Key Clinical Message: Clinicians should consider spontaneous coronary artery dissection in middle-aged women presenting with acute coronary syndromes and a history of tamoxifen use, to ensure timely diagnosis, and appropriate management strategies.

Abstract: Spontaneous coronary artery dissection (SCAD) is characterized by a non-iatrogenic, nontraumatic separation of the coronary artery wall, contributing to acute coronary syndromes (ACS), and sudden cardiac death. SCAD predominantly affects the left anterior descending artery (LAD) and is frequently observed in middle-aged women.
