We aimed to assess the impact of diabetes on the postoperative outcomes of bariatric surgery and compare three techniques: sleeve gastrectomy, Roux-en-Y, and gastric banding. : We extracted data from the National Inpatient Sample (2015-2019) using ICD codes.

Dysregulation of long non-coding RNA gene expression pathways in monocytes of type 2 diabetes patients with cardiovascular disease.

Background: Monocytes play a central role in the pathophysiology of cardiovascular complications in type 2 diabetes (T2D) patients through different mechanisms. We investigated diabetes-induced changes in lncRNA genes from T2D patients with cardiovascular disease (CVD), long-duration diabetes, and poor glycemic control.

Methods: We performed paired-end RNA sequencing of monocytes from 37 non-diabetes controls and 120 patients with T2D, of whom 86 had either macro or microvascular disease or both.

QPGx-CARES: Qatar pharmacogenetics clinical applications and research enhancement strategies.

Pharmacogenetic (PGx)-informed medication prescription is a cutting-edge genomic application in contemporary medicine, offering the potential to overcome the conventional "trial-and-error" approach in drug prescription. The ability to use an individual's genetic profile to predict drug responses allows for personalized drug and dosage selection, thereby enhancing the safety and efficacy of treatments. However, despite significant scientific and clinical advancements in PGx, its integration into routine healthcare practices remains limited.

Acute Triple Coronary Artery Occlusion Leading to Cardiogenic Shock and Cardiac Arrest Emphasizing the Role of Mechanical Circulatory Support (Escalate before It's Too Late).

We report a case of cardiac arrest in a 38-year-old male with no past medical history who presented as a case of ST-segment elevation myocardial infarction, and coronary angiography showed triple coronary artery thrombosis complicated with cardiogenic shock (CS) that warrants starting on inotropic support and insertion of intra-aortic balloon pump. CS diagnosis with a high likelihood of deterioration was established based on hemodynamics assessment; hence, an early prompt decision for escalation of mechanical circulatory support to Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) was made, which helped to prevent the patient's further deterioration and organ damage. The patient had uneventful VA-ECMO decannulation and was transferred to the ward and discharged after 28 days in stable condition on oral medical therapy and was following up regularly in the cardiology clinic.

The Effect of Beta-Blocker Post-Myocardial Infarction With Ejection Fraction >40% Pooled Analysis From Seven Arabian Gulf Acute Coronary Syndrome Registries.

The use of beta-blockers (BB) in reduced left ventricular ejection fraction (LVEF) post-myocardial infarction (MI) is associated with reduced 1-year mortality, while their role in patients with mid-range and preserved LVEF post-MI remains controversial. We studied 31,620 patients who presented with acute coronary syndrome (ACS) enrolled in seven Arabian Gulf registries between 2005 and 2017. Patients with LVEF ≤40% were excluded.

Predictors of 30-Day Re-admission in Cardiac Patients at Heart Hospital, Qatar.

Background: Cardiovascular disease patients are more likely to be readmitted within 30 days of being discharged alive. This causes an enormous burden on health-care systems in terms of poor care of patients and misutilization of resources.

Aims And Objective: This study aims to find out the risk factors associated with 30-day readmission in cardiac patients at Heart Hospital, Qatar.

Type 2 diabetes and in-hospital sudden cardiac arrest in ST-elevation myocardial infarction in the US.

Aims: We aimed to assess the impact of diabetes on sudden cardiac arrest (SCA) in US patients hospitalized for ST-elevation myocardial infarction (STEMI).

Methods: We used the National Inpatient Sample (2005-2017) data to identify adult patients with STEMI. The primary outcome was in-hospital SCA.

Characteristics and predictors of out-of-hospital cardiac arrest in young adults hospitalized with acute coronary syndrome: A retrospective cohort study of 30,000 patients in the Gulf region.

Introduction: The characteristics of young adults with out-of-hospital cardiac arrest (OHCA) due to acute coronary syndrome (ACS) has not been well described. The mean age of gulf citizens in ACS registries is 10-15 years younger than their western counterparts, which provided us with a unique opportunity to investigate the characteristics and predictors of OHCA in young adults presenting with ACS.

Methodology: This was a retrospective cohort study using data from 7 prospective ACS registries in the Gulf region.

Atrioventricular Conduction Disorders as a Complication of Inferior ST-Elevation Myocardial Infarction in Patients with COVID-19 Infection.

This case series demonstrates how COVID-19 infection might affect the heart in the context of acute myocardial infarction. Atrioventricular (AV) block might appear as one of the significant cardiac complications of acute MI in patients who tested COVID-19 PCR positive regardless of the presence of CVOID-19 infection symptoms. In our series, conduction disorders as a complication of acute inferior STEMI are more common in patients who tested positive for the COVID-19 infection.

Diabetes outcomes in heart failure patients with hypertrophic cardiomyopathy.

We aimed to assess diabetes outcomes in heart failure (HF) patients with hypertrophic cardiomyopathy (HCM). The National Inpatient Sample database was analyzed to identify records from 2005 to 2015 of patients hospitalized for HF with concomitant HCM. We examined the prevalence of diabetes in those patients, assessed the temporal trend of in-hospital mortality, ventricular fibrillation, atrial fibrillation, and cardiogenic shock and compared diabetes patients to their non-diabetes counterparts.

Validation of Polygenic Risk Scores for Coronary Heart Disease in a Middle Eastern Cohort Using Whole Genome Sequencing.

Background: Enthusiasm for using polygenic risk scores (PRSs) in clinical practice is tempered by concerns about their portability to diverse ancestry groups, thus motivating genome-wide association studies in non-European ancestry cohorts.

Methods: We conducted a genome-wide association study for coronary heart disease in a Middle Eastern cohort using whole genome sequencing and assessed the performance of 6 PRSs developed with methods including LDpred (PGS000296), metaGRS (PGS000018), Pruning and Thresholding (PGS000337), and an EnsemblePRS we developed. Additionally, we evaluated the burden of rare variants in lipid genes in cases and controls.

Gender Association with Incidence, Clinical Profile, and Outcome of Out-of-Hospital Cardiac Arrest: A Middle East Perspective.

Background: Out-of-hospital cardiac arrest (OHCA) is a leading cause of death worldwide. However, there is limited information on the outcome of the OHCA in the Middle East population, and limited studies have been carried out in the Arab Gulf countries. Hence, we aim to study the incidence and rate of survival in the OHCA setting and to assess the impact of gender on the clinical outcome following OHCA.

Khat Chewing and Cardiovascular Disease.

Khat chewing is a deeply rooted habit in Yemen. It has social, economic, and medical problems. Chronic use of khat chewing increases the risk of many medical complications.

Comparison of in-hospital and out-of-hospital cardiac arrest of trauma patients in Qatar.

Background: Cardiac arrests in admitted hospital patients with trauma have not been described in the literature. We defined "in-hospital cardiac arrest of a trauma" (IHCAT) patient as "cessation of circulatory activity in a trauma patient confirmed by the absence of signs of circulation or abnormal cardiac arrest rhythm inside a hospital setting, which was not cardiac re-arrest." This study aimed to compare epidemiology, clinical presentation, and outcomes between in- and out-of-hospital arrest resuscitations in trauma patients in Qatar.

The Prevalence and Genetic Spectrum of Familial Hypercholesterolemia in Qatar Based on Whole Genome Sequencing of 14,000 Subjects.

Familial hypercholesterolemia (FH) is an inherited disease characterized by reduced efficiency of low-density lipoprotein-cholesterol (LDL-C) removal from the blood and, consequently, an increased risk of life-threatening early cardiovascular complications. In Qatar, the prevalence of FH has not been determined and the disease, as in many countries, is largely underdiagnosed. In this study, we combined whole-genome sequencing data from the Qatar Genome Program with deep phenotype data from Qatar Biobank for 14,056 subjects to determine the genetic spectrum and estimate the prevalence of FH in Qatar.
