Insights

Off-pump coronary artery bypass grafting (CABG) has a low incidence of postoperative atrial fibrillation (POAF). Chronic renal failure and exclusive use of venous grafts are key predictors of POAF in these patients.

Area of Science:

  • Cardiovascular Surgery
  • Cardiac Surgery Outcomes
  • Arrhythmia Research

Background:

  • Postoperative atrial fibrillation (POAF) is a significant concern following coronary artery bypass grafting (CABG).
  • Off-pump CABG (OPCABG) may offer potential benefits in reducing POAF incidence.
  • Understanding POAF predictors in OPCABG is crucial for patient management.

Purpose of the Study:

  • To determine the incidence of POAF in patients undergoing CABG without cardiopulmonary bypass (CPB).
  • To identify independent predictor factors for POAF in the context of OPCABG.

Main Methods:

  • Retrospective cohort study of 280 patients undergoing OPCABG from December 2008 to December 2011.
  • Evaluation of patient characteristics, comorbidities (including chronic renal failure), and graft types (arterial vs. venous).
  • Statistical analysis using univariate and multivariate models to identify POAF predictors.

Main Results:

  • The overall incidence of POAF after OPCABG was 5.0%.
  • Chronic renal failure (CRF) was independently associated with an increased risk of POAF (OR, 3.31).
  • Exclusive use of venous-origin grafts also significantly increased POAF risk (OR, 9.81).

Conclusions:

  • Off-pump CABG is a safe and effective myocardial revascularization technique with a low POAF rate.
  • Chronic renal insufficiency is an independent risk factor for POAF after OPCABG.
  • The sole use of venous grafts is a significant predictor of POAF in OPCABG patients.

Amyloid Fibrils03:03

Amyloid Fibrils

Amyloid fibrils are aggregates of misfolded proteins.  Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils. 
Amyloid deposits were observed as early as 1639 in the liver and the spleen.   In 1854, Rudolph Virchow performed iodine staining,...

Cardiopulmonary Resuscitation I: Adult

Cardiopulmonary resuscitation, or CPR, is a life-saving emergency procedure performed when a person's heart has stopped beating or they are no longer breathing. The foundation of CPR is Basic Life Support (BLS), which focuses on the early recognition of cardiac arrest, the immediate start of high-quality chest compressions, and the timely use of an automated external defibrillator (AED).Assessing Responsiveness and Checking the Carotid PulseWhen approaching an unresponsive person, first ensure...

Fibril-associated Collagen

Fibril-associated collagens are a type of collagens present in the extracellular matrix with interrupted triple helices or FACIT (Fibril-associated collagens interrupted triple-helices). FACIT help connect and attach the collagen fibrils with each other as well as with other proteins of the extracellular matrix.
For example, the type II collagen fibrils in cartilage have covalently bound type IX fibril-associated collagens at regular intervals. Other types of fibril-associated collagens are...

Cardiopulmonary Resuscitation III: AED Use

Introduction to AEDAn Automated External Defibrillator (AED) is a portable medical device that analyzes the heart's rhythm and, if necessary, delivers an electrical shock to help the heart re-establish an effective rhythm during sudden cardiac arrest (SCA). SCA occurs when the heart suddenly and unexpectedly stops beating, leading to a loss of blood flow to the brain and other vital organs. In such emergencies, time is of the essence, and using an AED, combined with Cardiopulmonary...
