BACKGROUND: Myocardial injury after noncardiac surgery (MINS) is a major contributor to peri-operative morbidity and mortality with a reported incidence of about 8%. Tachycardia increases myocardial oxygen demand, and decreases oxygen supply, and is therefore a potential cause of MINS. OBJECTIVE: We tested the hypothesis that there is an association between intra-operative area above a heart rate (HR) of 90 bpm and a composite of MINS and in-hospital all-cause mortality...

Background: Although remote ischaemic preconditioning (RIP) provides protection against myocardial ischaemia and reperfusion injury during cardiac surgery, it is not widely used. Systemic intermittent hypoxic-hyperoxic training (IHHT) may be a suitable alternative. Methods: This is a prospective, single-centre, randomised controlled trial. 127 patients with ischaemic heart disease and indication for coronary artery bypass graft (CABG) surgery from the Cardiology Clinic IM Sechenov First Moscow State Medical University were randomly assigned to IHHT, IHHT-control or RIP...

BACKGROUND:  Periprocedural myocardial injury after coronary artery bypass grafting (CABG) may affect the patient's prognosis and may be due to a different set of factors beyond the atherosclerotic plaque instability. Considering the challenges in the diagnosis of myocardial injury after CABG, the aim of this study was to determine the association between postoperative early elevation of high-sensitivity troponin T (hsTnT) and all-cause 30-day mortality after CABG. METHODS:  We enrolled 600 consecutive patients who underwent CABG...

OBJECTIVE: Atrial fibrillation (AF) is one of the most common arrhythmias affecting the patient's quality of life, and its complications of thromboembolism can lead to serious consequences. AF patients are often in hypercoagulation status that can affect the prognosis. GPIIb/IIIa is a fibrinogen receptor that can bind to the ligands of platelet and cause aggregation. Therefore, GPIIb/IIIa can be treated as a marker of hemagglutination. This work aims to analyze the changes of GPIIb/IIIa after radiofrequency ablation of atrial fibrillation, and to investigate its relationship with recurrence...

PURPOSE OF REVIEW: Timely identification of high-risk surgical candidates facilitate surgical decision-making and allows appropriate tailoring of perioperative management strategies. This review aims to summarize the recent advances in perioperative risk stratification. RECENT FINDINGS: Use of indices which include various combinations of preoperative and postoperative variables remain the most commonly used risk-stratification strategy. Incorporation of biomarkers (troponin and natriuretic peptides), comprehensive objective assessment of functional capacity, and frailty into the current framework enhance perioperative risk estimation...

BACKGROUND: We tested the primary hypothesis that final intraoperative esophageal temperature is associated with increased odds of a composite of in-hospital all-cause mortality and myocardial injury within 7 days after noncardiac surgery. Secondary exposures were time-weighted average intraoperative temperature and area <37°C threshold. METHODS: Myocardial injury was defined by postoperative fourth-generation troponin T ≥0.03 ng/mL apparently due to cardiac ischemia...

BACKGROUND: Cellular injury is not avoidable with current cardioplegic solutions. The effect of adenosine on reducing cardiac injury post-surgery is controversial. The objective of the current study is to evaluate the effect of fast cardioplegic arrest induced by adenosine on high sensitive cardiac troponin I after heart valve surgery. METHODS: Forty-five patients with rheumatic heart diseases underwent heart valve surgery using conventional approach through median sternotomy...

BACKGROUND: Resting heart rate is well established as a predictor of morbidity and mortality in the general population. However, the relationship between preoperative heart rate and perioperative outcomes, specifically myocardial injury, is unclear. METHODS: This retrospective cohort study included patients undergoing elective major non-cardiac surgery from 2008 to 2014 at a multisite healthcare system. The exposure was ambulatory heart rate measured during the outpatient preoperative clinic visit, whereas the outcome of interest was myocardial injury (peak postoperative troponin I concentration >30 ng L-1 )...

An 84-year-old woman with previous spinal operations including vertebroplasty and lumbar decompressions was admitted electively under the spinal team for right-sided L4/5 decompression for worsening back pain which she undergoes using a posterior approach. Postoperatively, she develops stabbing upper central chest pain and given unremarkable chest X-ray, ECG and cardiac troponin, she undergoes a CT pulmonary angiogram which shows a fracture of the upper part of sternum but no pulmonary embolism. There is no history of recent trauma and this is deemed to be secondary to prolonged spinal surgery in the prone position in a patient with osteopenic bones...

BACKGROUND: Perioperative major adverse cardiovascular and cerebrovascular events (MACCEs) are incompletely understood, and risk prediction is imprecise. Atherogenic leukocytes are crucial in cardiovascular events. However, it is unclear if surgical interventions affect leukocyte counts or activation status. Therefore, we investigated whether noncardiac surgery in patients with elevated cardiovascular risk is associated with changes in atherogenic leukocyte subsets and if these changes are related to perioperative MACCEs...

Troponin-I (TN-I) levels are elevated following pediatric cardiac surgery with speculation that particular patterns may have prognostic significance. There is lack of procedure-specific data regarding postoperative TN-I levels in infants undergoing cardiac surgery. We hypothesized that TN-I elevation varies with type of surgery and persistent elevation predicts poor prognosis. We prospectively measured serial TN-I levels (preoperatively, 4, 8, 12, 24, and 48hours postoperatively) in 90 infants (age < 1 year) undergoing cardiac surgery: off cardiopulmonary bypass (CPB) (n = 15), on CPB (n = 43), and on CPB with ventricular incision (CPB with ventricular incision; n = 32)...

BACKGROUND: Cardiovascular events (CVE) might occur in 20% to 70% of liver transplant recipients, and major CVE are associated with poor long-term survival. Overall, the ability to identify patients at the highest risk of death after liver transplantation (LT) has been improved. Abnormal pretransplant troponin I (TnI) level is regarded as one of predictors of postoperative CVE. We evaluated the number of early CVE after LT and the impact of pretransplant TnI on cardiovascular morbidity...

BACKGROUND: Transit-time flow measurement (TTFM) should be routinely used in CABG surgery to verify graft function. Most recently, a 2D high-frequency-ultrasound (HF-US) epi-cardiac imaging probe has been released (MiraQTM, Medistim, Oslo, Norway), which allows to evaluate the cannulation/clamping site of the aorta morphologically and to evaluate the completed anastomosis. We aimed to evaluate the use of TTFM and HF-US on surgical strategy during CABG surgery. METHODS: A total of 65 consecutive patients undergoing CABG surgery were evaluated...

BACKGROUND: The recent technological evolution has also allowed for the treatment of juxtarenal aortic aneurysm (JAA) with an endovascular technique, but short- and long-term results must be compared with the results of open treatment, which is the gold standard. In this study, we analyzed the short- and long-term results of open surgical treatment (open repair) in patients with JAA in our series. METHODS: From January 2006 to December 2016, 155 patients were treated for JAA with open repair; the data were analyzed retrospectively...
