AI Article Synopsis

  • Patients who underwent coronary artery bypass grafting (CABG) are less likely to use certain preventive cardiovascular drugs at discharge compared to those who had percutaneous coronary intervention (PCI) after an acute coronary syndrome (ACS).
  • A study at St Paul's Hospital included 275 patients aged 18 and older, revealing that while both groups received common medications like acetylsalicylic acid and β-blockers, CABG patients received significantly fewer P2Y12 inhibitors and angiotensin-modulating agents.
  • Results indicate that while high use of acetylsalicylic acid, β-blockers, and statins was consistent across both groups, CABG patients had lower prescription rates for P2Y12 inhibitors and angiotensin-modulating

Article Abstract

Background: Data suggest that patients who undergo coronary artery bypass grafting (CABG) have a lower rate of secondary preventive cardiovascular pharmacotherapy use compared with patients who undergo percutaneous coronary intervention (PCI). This study sought to assess the rate of use of preventive pharmacotherapy at discharge in patients who underwent CABG vs PCI post-acute coronary syndrome (ACS).

Methods: A prospective cohort study was conducted at St Paul's Hospital in Vancouver, Canada. Patients aged ≥ 18 years who presented with an ACS and underwent CABG or PCI between January and November 2018 were included. Data on preventive pharmacotherapy use and reasons for justified nonuse (eg, intolerance, contraindication) were collected.

Results: A total of 275 patients were included. Mean age was 65 years, and 83% were male. Overall, 141 patients (51%) underwent CABG and 134 patients (49%) underwent PCI. All patients received acetylsalicylic acid, but more patients who underwent CABG received 325 mg (vs 80-81 mg) compared to PCI (25% vs 1%, 0.01). Use of P2Y12 inhibitors was higher in patients who underwent PCI (primarily ticagrelor) compared with patients who underwent CABG (primarily clopidogrel) (99% vs 26%, 0.01). All patients who underwent CABG received a β-blocker vs 96% of patients who underwent PCI ( 0.017). Use of angiotensin-modulating agents was higher in patients who underwent PCI (98% vs 65%, 0.01). Statin use was similar between groups (99% vs 99%, 0.96), but more patients who underwent PCI received maximum-dose therapy (89% vs 64%, 0.01).

Conclusions: Use of acetylsalicylic acid, β-blockers, and statins in patients post-ACS was high regardless of revascularization strategy, whereas P2Y12 inhibitors and angiotensin-modulating agents were underused in patients who underwent CABG even after adjusting for justified nonuse.

Objective: Awake, endoscopic spinal fusion has been utilized as an ultra-minimally invasive surgery technique to accomplish the goals of spinal fixation, fusion, and disc height restoration. While many techniques exist for this approach, this series represents a single institution's experience with a large cohort and the evolution of this method.

Methods: The medical records of a consecutive series of 400 patients treated over a 10-year period were retrospectively reviewed.

Objective: Endovascular treatment (EVT) is an effective treatment for patients with acute vertebrobasilar artery complex occlusion (VBAO). However, the benefit of bridging thrombolysis prior to EVT remains controversial. The purpose of the present study is to explore the best treatment strategy between bridging treatment (BT) and direct EVT in patients with acute VBAO.
