Filter by:Perioperative myocardial injury (PMI) after non-cardiac surgery (NCS), i.e. the elevation of postoperative troponin, occurs in nearly 20% of patients older than 45 years undergoing NCS and is independently and strongly associated with post-operative mortality (30-day mortality up to 10%). With over 300 million surgical interventions every year worldwide, PMI has a high clinical relevance on the health of the population. Heart rate (HR) is an independent and modifiable risk factor for PMI and death after non-cardiac surgery. Numerous studies showed that beta-blockers decrease myocardial ischemia after surgery in a heart-rate dependent manner, but this beneficial effect is surpassed by an increased incidence of perioperative hypotension and death. Currently, no single intervention is available to decrease the risk of perioperative cardiac complications. Ivabradine (IVA) is a negative chronotropic agent without significant effects on contractility or vascular tone and has been shown to improve outcomes in the setting of chronic and acute heart diseases. Rationale for pilot feasibility trial: the planned definitive large trial is a multicenter trial to investigate the efficacy of ivabradine to decrease perioperative myocardial injury. The intervention planned is complex and demands important resources. The investigators designed this pilot study to inform on the feasibility of the definitive large trial. This pilot study will also provide additional information that could help investigators improve the definitive large trial regarding recruitment, refinements to the study protocol and improving the participant's experience.
Previous report showed that 37% of patients with moderate to severe carbon monoxide (CO) poisoning experienced a myocardial injury, defined as elevated cardiac enzyme [creatine kinase, CK-MB, and cardiac troponin I (TnI)] or ischemic electrocardiogram (ECG) change. In other study, 24% of the patients with the myocardial injury after CO poisoning died during a median follow-up of 7.6 years. The myocardial injury was the major predictor of mortality. In addition, in the Taiwanese nationwide population-based cohort study, CO poisoning itself reported as a higher risk of a major adverse cardiovascular event. According to the previous study of investigators, among CO poisoned patients with myocardial injury, 74.4% of patients experienced CO-induced cardiomyopathy. All CO-induced cardiomyopathy recovered to normal status. In this situation, there is no definite approved reason why more cardiovascular events are occurred in CO poisoned patients with myocardial injury during long term follow-up period despite normalization of CO-induced elevated TnI and cardiac dysfunction. Two image cases related to cardiac magnetic resonance imaging (CMR) in acute CO poisoning previously reported. One image case reported that patient had mildly depressed left ventricular (LV) systolic function with hypokinesis of the anterior wall and regional akinesis of the inferior wall on the transthoracic echocardiography performed during hospitalization and late gadolinium-enhancement (LGE) images of CMR demonstrated multiple focal areas of high signal consistent with myocardial necrosis or fibrosis. Another image case reported an image case that in CMR, inferolateral mid-wall myocardial fibrosis, which was defined as LGE, was present despite the setting of a completely normal echocardiogram at 4-month follow-up in CO poisoned patients. Therefore, the investigators evaluate prevalence (frequency of LGE positive) and patterns (involved LV wall and range of LGE positive) of myocardial fibrosis (LGE positive) in acute CO-poisoned patients during acute (within seven days after CO exposure) and chronic phase (at 4-5 months after CO exposure) and whether LGE positive developed in acute phase have been changed through cardiac MRI performed at chronic phase. The investigators also evaluate LV ejection fraction and global longitudinal strain in transthoracic echocardiography performed at the ED (baseline) and within seven days (follow-up). The investigators also assessed the association between neurocognitive outcomes using the global deterioration scale (at 1, 6, and 12 months after CO exposure) and the presence of LGE positive.
Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) poses a significant threat to global health. As the disease progresses, a series of acute complications tend to develop in multiple organs. Beyond the supportive care, no specific treatment has been established for COVID-19. The effectiveness, both short-term and long-term, of some promising antivirals, such as the hydroxychloroquine combination with azithromycin, needs to be evaluated. This study aims to investigate the predictive role of cardiac biomarkers and pulmonary symptoms for late complications of COVID-19 coronavirus infection on the heart and lung in patients treated with the hydroxychloroquine / azithromycin combination therapy. Thus, COVID-19 coronavirus patients undergoing hydroxychloroquine / azithromycin combination therapy will be compared to patients not undergoing this therapy. The comparison will be made by the analysis of the relationships between (1) levels of ultrasensitive cardiac troponins collected at the beginning of the infection and cardiac magnetic resonance data in the 3rd and 12th months of troponin collection and (2) findings CT scans and the results of the ergospirometers tests performed in those same periods. It is expected to demonstrate that: (1) cardiac troponin and lung tomographic findings can predict late complications of COVID-19 coronavirus infection in the heart and lung, assessed by cardiac magnetic resonance and ergospirometers one year after the beginning of the infection, and (2) hydroxychloroquine / azithromycin combined therapy can abolish the onset of these complications late. Furthermore, the results may point to the need for more rigorous monitoring of cardiologists and pulmonologists of these patients, due to the risk of hemodynamic complications, arrhythmogenic and respiratory.
COVID-19 outbreak is often lethal. Mortality has been associated with several cardio-vascular risk factors such as diabetes, obesity, hypertension and tobacco use. Other clinico-biological features predictive of mortality or transfer to Intensive Care Unit are also needed. Cases of myocarditis have also been reported with COVID-19. Cardio-vascular events have possibly been highly underestimated. The study proposes to systematically collect cardio-vascular data to study the incidence of myocarditis and coronaropathy events during COVID-19 infection.We will also assess predictive factors for transfer in Intensive Care Unit or death.
Myocardial injury after noncardiac surgery (MINS) is common, silent, and strongly associated with morbi-mortality. There are some evidences in the littérature showing that troponin elevation pre and/or postoperatively and surgical Apgar score are strongly and independently associated with postoperative morbi-mortality. In this cohort study of orthopedic surgery patients (> 50years), the aim is to determine MINS incidence and to assess wich peri-operative factors are associated with the occurrence of MINS. The final objective is to create a score to better identified the patients with a MINS and a poor outcome.
Heart failure, one of the leading causes of connective tissue disease (CTD) mortality, has attracted increasing attention. Currently, no known study had focused on the effect of sacubitril/valsartan on right ventricular dysfunction and in the systemic disease induced heart disease. We aimed to observe the effect of sacubitril/valsartan on primary endpoints (6 minutes walking test and myocardial fibrosis) in CTD patients with right ventricular ejection fraction reduction (RV-HFrEF).
The "Hypotension Prediction Index (HPI)" was established by the Edwards Lifescience Company (Irvine, California, USA) and is CE certified. As part of the Edwards Acumen Decision-Support-Software-Suite the HPI is supported by the minimal invasive FloTrac Sensor. The HPI displays the probability of an occurring hypotension. The software was established with the help of 20.000 analyzed patient events. If the upper limit of the HPI is reached, the software is alarming the treating physician 8. At the university hospital of Giessen HPI analyses are used in the daily clinical routine as well as for scientific purposes. Preliminary data of the HPI-I-Trial ("Influence of the Hypotension Prediction Index on the number and duration of intraoperative hypotension in primary hip-endoprothetic replacement", University Hospital of Giessen) included patients, which underwent hip-endoprothetic replacement surgery and revealed that the use of HPI with a goal directed therapy (GDT) protocol compared to standard care significantly reduced the incidence and duration of intraoperative hypotension. Therefore HPI with GDT might reduce the incidence of hypotension related complications in a sicker patient cohort. The aim of the study is to investigate whether a goal directed treatment according to the Hypotension Prediction Index compared to standard care can reduce the incidence of intraoperative hypotension in patients under single lung ventilation.
Perioperative Myocardial Infarction (PMI) is a major contributor to perioperative mortality and morbidity with overall incidence of 5-16%. It is associated with increased 30-day mortality of 11.6% vs 2.2% of patients without PMI in non-cardiac surgical patients. However, its recognition and diagnosis remains challenging as the typical symptoms and findings of ischemic MI may be masked by post-operative changes and pain management. In this study, the investigators hope to determine if colchicine decreases the incidence of MINS in high risk surgical patients undergoing non-cardiac surgery and optimally establish colchicine as a viable therapy to improve perioperative cardiovascular outcome in those patients.
Recently, the use of preoperative BNP as a preoperative risk stratifcation tool was added to the Canadian Cardiovascular Society (CCS) guidelines (4) on perioperative cardiac risk assessment and management for patients who undergo noncardiac surgery, based on the prognostic value of preoperative BNP in indentifiy patients at significant risk of 30-day mortality, nonfatal myocardial infarction, or myocardial injury after noncardiac surgery (MINS). While the value of screening for high risk patients through the use of preoperative BNP been demonstrated, the management of postoperative ischemia is less clear. Therefore, this study aims to: 1. Evaluation of the use of BNP as a preoperative screening biomarker; how often is it ordered in Anesthesia Preadmission Clinic and what is the incidence of a positive result (BNP ≥ 92 ng/L) 2. Determine the incidence of myocardial injury after non-cardiac surgery (MINS) at 30 days and myocardial infarction at 1 year at a tertiary care center when BNP is used as a screening tool 3. Record patterns of management of patients with MINS 4. Determine the cost associated with the different patterns of management of MINS 5. Comparison with a cohort group who qualified for BNP screening according to CCS guidelines but did not have it measured. The investigators will attempt to evaluate the cohort group for MINS at 30 days and myocardial infarction at 1 year.
Del Nido cardioplegia has been used exclusively for myocardial protection in pediatrics cardiac surgery for decades. Its unique properties including lidocaine which helps counteract potassium depolarization of the myocardial cell membrane, inhibition of intracellular calcium accumulation, preservation of intracellular high-energy phosphates, free-radical scavenging and acid-base buffering have been proven to be very effective for myocardial protection during cardiac surgery for congenital heart disease and acquired heart disease. Recent studies have proven its safety, efficacy, and cost-effectiveness for myocardial protection in adult cardiac surgery as a single dose cardioplegia which is typically administered in a single dose fashion or with extended dosing intervals. In contrast, Traditional blood cardioplegia is commonly administered approximately every 20 minutes. These characteristics of del Nido cardioplegia allow for fewer interruptions and improve surgical workflow. The base solution for del Nido cardioplegia is normally Plasma-Lyte A (Baxter Healthcare Corporation, Deerfield, IL, USA) which has an electrolyte composition similar to the extracellular fluid and is calcium-free. Unfortunately, an unavailability of PlasmaLyte-A in many countries precluding utilization of del Nido cardioplegia with its normal base solution in many cardiac centers. To access the benefits of del Nido cardioplegia, we utilize lactated Ringer's solution as the base solution. This prospective randomized study aimed to evaluate myocardial preservation and clinical outcomes when using lactated Ringer's solution compared with PlasmaLyte-A as a base solution for del Nido cardioplegia.
