Temporal Trends in Race and Sex Differences in Cardiac Arrest Mortality in the USA, 1999-2020.

Background: Cardiac arrest (CA) affects over 600,000 patients in the USA annually. Despite large-scale public health and educational initiatives, survival rates are lower in certain racial and socioeconomic groups.

Methods: A county-level cross-sectional longitudinal study using death data of patients aged 15 years or more from the US Centers for Disease Control and Prevention's Wide-Ranging Online Data for Epidemiologic Research (WONDER) database from 1999 to 2020.

Procedural and cardiovascular outcomes of geriatric vs non-geriatric patients undergoing permanent pacemaker implantation - a nationwide cohort analysis.

Background: Permanent pacemaker implantation is increasing exponentially to treat atrio-ventricular block and symptomatic bradyarrhythmia. Despite being a minor surgery, immediate complications such as pocket infection, pocket hematoma, pneumothorax, hemopericardium, and lead displacement do occur.

Methods: The Nationwide Inpatient Sample was queried from 2016 to 2018 to identify patients with pacemakers using ICD-10 procedure code.

Detection of myocardial dysfunction using global longitudinal strain with speckle-tracking echocardiography in patients with vs without rheumatoid arthritis: a systematic review and meta-analysis.

Objectives: Rheumatoid arthritis (RA) is a systemic autoimmune disorder primarily involving the peripheral joints. Systemic involvement can occur, including myocardial dysfunction. Speckle tracking echocardiography (STE) is a novel diagnostic study which is recently being used to detect subclinical cardiac dysfunction.

Valve-in-valve transcatheter aortic valve replacement versus redo surgical valve replacement for degenerated bioprosthetic aortic valve: An updated meta-analysis comparing midterm outcomes.

Background: Redo surgical aortic valve replacement (redo SAVR) and valve-in-valve transcatheter aortic valve replacement (ViV TAVR) are the two treatment strategies available for patients with severe symptomatic bioprosthetic aortic valve dysfunction. Herein, we performed a systematic review and meta-analysis comparing both early and mid-term outcomes of ViV TAVR versus redo SAVR in patients with bioprosthetic aortic valve disease.

Methods: PubMed, Cochrane reviews, and Google scholar electronic databases were searched and studies comparing ViV TAVR versus redo SAVR were included.

Prevalence of sustained hypertension and obesity among urban and rural adolescents: a school-based, cross-sectional study in North India.

Objective: Recent data on sustained hypertension and obesity among school-going children and adolescents in India are limited. This study evaluates the prevalence of sustained hypertension and obesity and their risk factors among urban and rural adolescents in northern India.

Setting: A school-based, cross-sectional survey was conducted in the urban and rural areas of Ludhiana, Punjab, India using standardised measurement tools.

Intra-operative uterine artery embolization with caesarean delivery in an adjoining operating theatre and catheter lab (OT/CL) complex vs. conventional management in patients with abnormally invasive placenta: a retrospective case control study.

Patients of abnormally invasive placenta (AIP) undergoing caesarean delivery are at increased risk of haemorrhage. Conventional management includes piecemeal removal of placenta or placenta left . However, they often require hysterectomy after delivery.

Determinants of in-hospital clinical outcome in patients with sub-massive pulmonary embolism.

Introduction: There is limited data regarding in hospital determinants of clinical deterioration and outcome in sub massive pulmonary embolism (PE). We aimed to evaluate these determinants by comparing biomarkers, CT pulmonary angiogram echocardiography, electrocardiography variables.

Methods: 57 patients of sub massive PE diagnosed on CT pulmonary angiogram were included.

Factors influencing prehospital delay in patients presenting with ST-elevation myocardial infarction and the impact of prehospital electrocardiogram.

Background: In ST-elevation myocardial infarction (STEMI), prehospital delay is a significant factor, decreasing likelihood of revascularization and increasing mortality. Prehospital delays are substantive in Indian patients with STEMI. Our study aimed to investigate factors associated with prehospital delay in patients with STEMI.
