AI Article Synopsis

  • This study investigates how serum calcium (SC) levels relate to the occurrence of postoperative atrial fibrillation (POAF) in patients undergoing heart surgery.
  • It analyzed data from over 12,000 patients, revealing that those with low SC levels had a significantly higher rate of POAF compared to those with normal levels.
  • The findings suggest that low SC levels are a risk factor for POAF, regardless of other factors like age, sex, and pre-existing health conditions.

Article Abstract

Objectives: This study aims to investigate the relationship between serum calcium (SC) levels and the incidence of postoperative atrial fibrillation (POAF) in patients undergoing coronary artery bypass graft surgery.

Methods: This retrospective, observational cohort study consecutively enrolled patients undergoing isolated coronary artery bypass grafting in Beijing Anzhen Hospital from January 2018 to December 2021. Patients with a previous history of atrial fibrillation or atrial flutter or requiring concomitant cardiac surgery were excluded. A logistic regression model was used to determine predictors of POAF. Multivariable adjustment, inverse probability of treatment weighting and propensity score matching were used to adjust for confounders. Moreover, we conducted univariable and multivariable logistic regression analyses on preoperative and postoperative SC and ionized SC levels.

Results: The analysis encompassed 12 293 patients. The POAF rate was significantly higher in patients with low SC level than those without (1379 [33.9%] vs 2375 [28.9%], P < 0.001). Low SC level was associated with an increased odds ratio of POAF (odds ratio [95% confidence interval]: 1.27 [1.18-1.37], P < 0.001). Inverse probability of treatment weighting and propensity score matching analyses confirmed the results. The increased POAF rate in low SC level group still existed among subgroup analysis based on different age, sex, body mass index, hypertension, hyperlipidaemia, CHA2DS2-VASc and magnesium.

Conclusions: Low SC level indicates elevated POAF risk in patients undergoing isolated coronary artery bypass graft surgery even after the adjustment for age, sex, cardiovascular risk factors, echocardiographic parameters and laboratory markers.

Enhanced Endothelialization Using Resveratrol-Loaded Polylactic Acid-Coated Left Atrial Appendage Occluders in a Canine Model.

ACS Appl Bio Mater

State Key Laboratory of Cardiovascular Disease, National Center for Cardiovascular Diseases, Chinese Academy of Medical Sciences & Peking Union Medical College, Fuwai Hospital, 167 Beilishi Road, Xicheng District, Beijing 100037, China.

Left atrial appendage occlusion (LAAO) is a well-established alternative to anticoagulation therapy for patients with atrial fibrillation who have a high bleeding risk. After occluder implantation, anticoagulation therapy is still required for at least 45 days until complete LAAO is achieved by neoendocardial coverage of the device. We applied a polylactic acid-resveratrol coating to the LAAO membrane to enhance endothelialization with the goal of shortening the anticoagulation therapy duration.

Aims: Atrial fibrillation (AF) accounts for about 20% of all ischemic strokes worldwide. It is known that AF impairs health-related quality of life (HRQOL) in the general population, but data on HRQOL in stroke patients with newly diagnosed AF are sparse.

Methods: Post hoc analysis of the prospective, investigator-initiated, multicenter MonDAFIS study (NCT02204267) to analyze whether AF-related oral anticoagulation (OAC), and/or AF-symptom severity are associated with HRQOL after ischemic stroke or transient ischemic attack (TIA).

Background: Heart failure (HF) is a risk factor for stroke among people with atrial fibrillation (AF). Prognosis following a HF diagnosis is often poor, but this is not accounted for in existing stroke risk scores.

Aim: To examine stroke incidence in people with HF and AF compared to AF alone, considering the competing risk of death.

Background: Aortic stenosis (AS) is a complex condition with various hemodynamic subtypes, each with distinct clinical profiles and outcomes. This study aimed to assess the characteristics and outcomes of different AS phenotypes based on flow and gradient patterns.

Methods: In this retrospective cohort study, we included 930 patients who underwent transcatheter aortic valve replacement (TAVR) for severe symptomatic AS at Mayo Clinic sites from 2012-2017.
