HbA1C's predictive value for postoperative complications in cardiac surgery has been mixed. Studies did not account for HbA1C being over-read in anemic patients. This study proposes a novel way of using a ratio of HbA1C over hemoglobin (HH ratio). Retrospective recruitment of patients undergoing cardiac surgery was done with ethics approval. The primary objective of our study is to look for the correlation of HH ratio with 90-day (short-term) and 1-year (long-term) mortality. The secondary objective is to investigate its association with other adverse events. Statistical analysis was done using multivariable regressions and Cox proportional hazard models. Of the 974 patients recruited, 618 had a HH Ratio0.7 was associated with 90-day mortality (HR 5.12, P = 0.033 and HR 7.25, P= 0.048 respectively) and 1-year mortality (HR 4.53, P = 0.028 and HR 9.20, P = 0.022 respectively). The higher HH ratio groups were also associated with increased length of stay (hours) in the intensive care unit (P less then 0.001) and renal complications (P less then 0.001). Our study showed a positive association of HH ratio with 90-day and 1-year mortality and postoperative adverse outcomes in patients undergoing cardiac surgery. The HH ratio has the potential to be a new perioperative target.Aortic arch pathologies have been a surgical challenge, involving cerebral, visceral and myocardial protection. Innovative techniques including total arch replacement and frozen elephant trunk had evolved over last decades with promising mid-term outcomes. We evaluate our mid-term outcomes on total arch replacement with frozen elephant trunk and the role of timely second staged interventions. Between August 2014 and April 2020, 41 patients with aortic arch pathologies underwent total arch replacement with frozen elephant trunk with Thoraflex-Hybrid-Plexus device (Vascutek, Inchinnan, Scotland). Patients' perioperative, clinical and radiological outcomes were reviewed. check details Post discharge survival (n = 37) at 3 year was 100%. Overall survival of 85.3% over a median follow up of 3.3 years, inpatient mortality of 9.8%. Distribution of aortic pathologies with acute type A dissection or intramural hematoma (n = 15, 36.6%), thoracic aortic aneurysm, including arch and descending aortic aneurysm (n = 9, 22%) and chronic aortic dissection including chronic type A and type B dissections (n = 13, 31.7%). Mean operative, circulatory arrest, and antegrade cerebral perfusion time were 417 ± 121 minutes, 89 ± 28 minutes, and 154 ± 43 minutes, respectively. Second stage procedures were performed in 32% and distal stent graft induced new entry was observed in 19% of patients. We reported an Asian series of Thoraflex with outstanding midterm clinical outcomes, given descending aortic pathologies were tackled with a timely second stage interventions. The observation of aortic remodeling and distal stent graft induced new entry requires further investigations.The present study aims to investigate whether preoperative statin use is associated with less postoperative atrial fibrillation occurrence after septal myectomy in patients with hypertrophic obstructive cardiomyopathy (HOCM). Clinical data of consecutive patients with HOCM who underwent septal myectomy between February 2009 and May 2019 at our institution was retrospectively reviewed. The cohort was divided into 2 groups according to the status of preoperative statin use (statin group vs no statin group). Logistic regression was used to explore associations of clinical variables with postoperative atrial fibrillation occurrence. A total of 1307 patients with HOCM underdoing septal myectomy were included in the present study, with 109 patients in the statin group and 1198 in the no statin group. Among 322 patients (24.6%) developing postoperative atrial fibrillation, 21 cases (19.3%) occurred in the statin group, while 301 cases (25.1%) were in the no statin group (P = 0.202). After propensity score matching with confounding variables at baseline, 91 paired patients were included in the matched cohort. Postoperative atrial fibrillation developed in 17 (18.7%) and 38 (41.8%) in the statin and no statin groups, respectively (P = 0.001). Preoperative statin use was associated with less postoperative atrial fibrillation occurrence (odds ratio 0.220, 95% confidence interval 0.083-0.588, P less then 0.003). The present study suggested that preoperative statin use was associated with less postoperative atrial fibrillation occurrence after septal myectomy in patients with HOCM. This finding may provide clues for subsequent prospective study to investigate this clinical issue.To review the incidence of retrograde type A aortic dissection (RTAD) after thoracic endovascular aortic repair (TEVAR) of patients with type B aortic dissection, and to investigate its time trends and underlying risk factors. The incidence rate of RTAD after TEVAR for type B aortic dissection was gathered as a cumulative pool for each year in meta-analysis. Linear regression was used to establish the temporal trend of RTAD incidence. Annual decrease rate was calculated for the fulltime frame. Sixty-six articles were included in this study, which represented 11,149 patients enrolled since 1994, and the research published between 2000 and 2019. The overall pooled rate of RTAD incidence is 2.20% (95% confidence interval 0.0162-0.0284; P less then 0.0001). The incidence numbers fluctuated for many years while continuing to decline, ultimately reaching a valley in 2016-2017. The linear regression analysis identified a 0.4% decrease in incidence rate along with a declining oversize rate of stent-grafts. The overall average incidence of RTAD in the past 21 years was 2.2%. The downward incidence trend may be attributed to the lower oversize rate and the improved design of stent-grafts, as well as sophisticated manipulation and delayed TEVAR intervention.Fluoroquinolone use has been associated with collagen disease events, raising safety concerns. We hypothesized that the use of fluoroquinolones is associated with aortic aneurysm (AA) and aortic dissection or aortic rupture (AD/AR). We performed a systematic review with meta-analysis on studies published until March 2019. Seven observational studies were included, comprising 2,851,646 participants. The studies were evaluated regarding their risk of bias. Results on fluoroquinolone use risk comparing with nontreatment and with beta-lactam antibiotic use were extracted. The estimates were pooled through a random-effects model meta-analysis and heterogeneity assessed through the I2 statistic. Sensitivity analysis were performed, grouping studies per design and with exclusion of studies with critical risk of bias. Fluoroquinolone use was associated with a higher risk of AA/AD/AR, comparing with a nontreatment intervention (odds ratio = 2.26; 95%CI 1.93-2.65; I2 = 30%) and comparing with a beta-lactam intervention (odds ratio = 1.
