Unlocking the enigma: decoding premature ventricular complexes for effective clinical assessment and risk management.

The identification of ventricular premature complexes during a cardiological evaluation necessitates the implementation of diagnostic processes aimed at discerning the clinical context that may predispose individuals to a high risk of sudden cardiac death. Epidemiological studies reveal that ventricular premature beats occur in approximately 75% of healthy (or seemingly healthy) individuals, as long as there is no evidence of underlying structural heart disease, such as benign idiopathic ventricular extrasystole originating from the right and left ventricular outflow tracts. In the real world, however, ventricular ectopic beats with morphologies very similar to seemingly benign occurrences are not uncommon.

Association of hospital-based substance use supports on emergency department revisits: a retrospective cohort study in Sudbury, Canada from 2018 to 2022.

Background: This study compares emergency department (ED) revisits for patients receiving hospital-based substance-use support compared to those who did not receive specialized addiction services at Health Sciences North in Sudbury, Ontario, Canada.

Methods: The study is a retrospective observational study using administrative data from all patients presenting with substance use disorder (SUD) at Health Sciences North from January 1, 2018, and August 31, 2022 with ICD-10 codes from the Discharge Abstract Database (DAD) and the National Ambulatory Care Database (NACRS). There were two interventions under study: addiction medicine consult services (AMCS group), and specialized addiction medicine unit (AMU group).

Canadian Addiction Treatment Centre (CATC) opioid agonist treatment cohort in Ontario, Canada.

Purpose: The Canadian Addiction Treatment Centre (CATC) cohort was established during a period of increased provision of opioid agonist treatment (OAT), to study patient outcomes and trends related to the treatment of opioid use disorder (OUD) in Canada. The CATC cohort's strengths lie in its unique physician network, shared care model and event-level data, making it valuable for validation and integration studies. The CATC cohort is a valuable resource for examining OAT outcomes, providing insights into substance use trends and the impact of service-level factors.

Outcomes of Total Aortic Arch Replacement in a Canadian Nationwide Registry.

Background: Accurate benchmarking of outcomes after elective open total arch replacement is important for surgical decision making and for comparisons with emerging endovascular technologies.

Methods: A multicentre registry of consecutive aortic arch procedures in 9 centres across Canada contained 250 elective total arch replacements from 2010 to 2021. A total of 728 patients undergoing elective hemiarch replacement over the same time period was used as a comparator group.

Cardiovascular Events After Aortic Root Repair in Patients With Marfan Syndrome.

Background: The usefulness of aortic valve sparing operations to treat aortic root aneurysm in patients with Marfan syndrome (MS) remains controversial.

Objectives: The purpose of this study was to evaluate the occurrence of cardiovascular events in patients with MS who have undergone valve-preserving aortic root replacement.

Methods: Patients with MS who had aortic valve sparing operations (reimplantation of the aortic valve or remodeling of the aortic root) from 1988 through 2019 were followed prospectively for a median of 14 years.
