Post-COVID-19 Tachycardia Syndrome: A Distinct Phenotype of Post-Acute COVID-19 Syndrome.

In this paper we highlight the presence of tachycardia in post-acute COVID-19 syndrome by introducing a new label for this phenomenon-post-COVID-19 tachycardia syndrome-and argue that this constitutes a phenotype or sub-syndrome in post-acute COVID-19 syndrome. We also discuss epidemiology, putative mechanisms, treatment options, and future research directions in this novel clinical syndrome.

The Effects of Hydroxyurea Therapy on the Six-Minute Walk Distance in Patients with Adult Sickle Cell Anemia: An Echocardiographic Study.

Background: The impact of hydroxyurea (HU) medication as treatment of choice has not been evaluated in adult sickle cell anemia (SCA) patients in terms of the 6-min walk distance (6 MWD).

Aim: The aim of the study was evaluating the effects of HU on the 6 MWD, serum brain natriuretic peptide (NT-pro BNP) level, and pulmonary hypertension (PH) measured by tricuspid regurgitation velocity (TRV).

Methods: In this cross-sectional, prospective study, 110 patients with homozygous SCA were studied and compared with age- and gender-matched healthy controls.

Diabetes and Mortality in Acute Coronary Syndrome: Findings from the Gulf COAST Registry.

Background: The prevalence of traditional risk factors such as diabetes mellitus (DM) and obesity are increasing in patients with acute coronary syndrome (ACS). Furthermore, outcomes after ACS are worse in patients with DM. The high prevalence of DM and an early age at onset of ACS have been described in prior publications from the Gulf Coast Database.

Awareness, understanding, attitude and barriers toward prescribing modern cancer immunotherapies in the Arabian Gulf countries.

Introduction: The use of modern immunotherapy has been evolving over the past few years, and various new agents have been developed for new indications at multiple primary sites in oncology. It is important for physicians who are involved in cancer care to be aware and updated about new therapeutic agents and their indications, potential benefits, and side effects.

Patients And Methods: From October to November 2017, we conducted a survey on the awareness, understanding, attitude, and barriers associated with prescribing modern cancer immunotherapies among physicians in the Arabian Gulf countries.

Risk Stratification and in Hospital Morality in Patients Presenting with Acute Coronary Syndrome (ACS) in Bahrain.

Background: Risk factors and short-term mortality in patients presented with Acute Coronary Syndrome (ACS) in Bahrain has not been evaluated before.

Aim: In this prospective observational study, we aim to determine the clinical risk profiles of patients with ACS in Bahrain and describe the incidence, pattern of presentation and predictors of in-hospital clinical outcomes after admission.

Methods: Patients with ACS were prospectively enrolled over a 12 month period.

Penetrating Injury of the Heart From a Chronically Migrating Foreign Body.

A 46-year-old man experienced a remote unexpected lung injury with a sharp object. The object migrated over the years, penetrating the mediastinal structure, injuring the pericardium and the right-sided chambers of the heart. The injury was complicated by hemodynamic instability and pericardial tamponade.

Stent Thrombosis after Rescue Percutaneous Coronary Intervention in Acute ST-Segment Elevation Myocardial Infarction.

Main Problem: To determine the incidence of coronary stent thrombosis (ST) in patients with acute ST segment elevation myocardial infarction (STEMI) after rescue percutaneous coronary intervention (PCI).

Methods: An observational study looking at the incidence of ST in a middle-eastern population. A total of 510 consecutive patients presented with ST-segment elevation myocardial infarction (STEMI) were enrolled and underwent thrombolytic therapy with a total follow-up period of 2 years.

Design and Rationale of Gulf locals with Acute Coronary Syndrome Events (Gulf Coast) Registry.

Objectives: To describe the risk profile, management and one-year outcomes of patients hospitalized with acute coronary syndrome (ACS) in the Gulf region of the Middle East.

Subjects And Methods: The Gulf locals with acute coronary syndrome events (Gulf COAST) registry is a prospective, multinational, longitudinal, observational, cohort-based registry of consecutive citizens, from the Gulf region of the Middle East, admitted from January 2012 to January 2013 to 29 hospitals with a diagnosis of ACS. Data entered online included patient demographics, cardiovascular risk profiles, past medical history, physical findings on admission, in-hospital diagnostic tests and therapeutic management, as well as one year outcomes.

Elevated plasma fibrinogen rather than residual platelet reactivity after clopidogrel pre-treatment is associated with an increased ischemic risk during elective percutaneous coronary intervention.

Objectives: This study was undertaken to determine the roles of serum fibrinogen and residual platelet reactivity after clopidogrel pre-treatment on ischemic events after elective percutaneous coronary intervention (PCI).

Background: Both elevated serum fibrinogen and high platelet reactivity with thienopyridines are associated with ischemic cardiovascular events. Elevated fibrinogen also contributes to high on-clopidogrel platelet reactivity.

Multicenter international registry of unprotected left main coronary artery percutaneous coronary intervention with everolimus-eluting stents.

Objective: The aim of this study was to assess the clinical outcomes of percutaneous coronary intervention (PCI) with everolimus-eluting stents (EES) for the treatment of unprotected left main coronary artery (ULMCA) disease.

Background: The standard of care for the treatment of ULMCA disease is coronary artery bypass grafting (CABG). Data suggest that PCI with drug-eluting stents is a viable alternative to CABG for the treatment of ULMCA disease.

Coarctation of the thoracic aorta masquerading as bilateral aorto-iliac stenosis.

We present a case with coarctation of the aorta (CoA) with lifestyle limiting claudication and lower extremity weakness, successfully treated with surgical correction. The presented case discusses the diagnostic challenges associated with identifying CoA in patients with claudication.

Successful treatment of in-stent restenosis of a covered stent graft with a paclitaxel-eluting stent.

We present the case of a 58-year-old male with coronary artery disease and a significant stenosis of the left circumflex artery that was preceded by a coronary aneurysm. The stenosis and aneurysm were treated successfully with a coronary stent graft. The patient subsequently developed in-stent restenosis (ISR).
