BACKGROUND: Myocardial injury after noncardiac surgery, as measured by troponin elevation, is strongly associated with mortality. However, it is unknown in which patients prognosis can be improved. The presence of kinetic changes of troponin may be associated with a worse prognosis and warrant more aggressive management. Therefore, we aimed to study the kinetics of troponin in patients with postoperative myocardial injury, and to determine the added predictive value of kinetic changes of troponin on mortality...

OBJECTIVE: The aim of this study is to identify the association between early postoperative troponin elevations and outcomes after major colorectal surgery. BACKGROUND: Myocardial infarction is the leading cause of death after noncardiac surgery. Most postoperative myocardial infarctions are clinically silent, and asymptomatic troponin elevations have the same early mortality as symptomatic infarctions. METHODS: Patients over the age of 45, undergoing major colorectal surgery from March 2015 to January 2016, were identified...

Myocardial injury is the most common cause of death during the 30 days after noncardiac surgery. Only 14% of patients who are experiencing a perioperative myocardial infarction will have chest pain, and 65% are entirely clinically silent, which means that they will go undetected without routine troponin screening. Although it is tempting to dismiss asymptomatic troponin elevation, mortality is similar with and without symptoms. Furthermore, mortality at 30 days in patients who have postoperative troponin elevation is a concerning 10%, which represents a 5-fold increase from background risk...

BACKGROUND: To evaluate the role of routine troponin surveillance in patients undergoing major noncardiac surgery, unblinded screening with cardiac consultation per protocol was implemented at a tertiary care center. In this study, we evaluated 1-year mortality, causes of death, and consequences of cardiac consultation of this protocol. METHODS: This observational cohort included 3224 patients ≥60 years old undergoing major noncardiac surgery. Troponin I was measured routinely on the first 3 postoperative days...

PURPOSE OF REVIEW: To review myocardial injury after noncardiac surgery (MINS), focusing on recent studies, including data on high-sensitivity troponin, which is likely to alter our understanding of MINS. RECENT FINDINGS: MINS is greatly underappreciated by clinicians, possibly because of its silent presentation. However, MINS is both common and clinically important. In total, 8% of at-risk patients will suffer a MINS, an event that is associated with death within 30 days with an odds ratio of 3...

BACKGROUND: Myocardial injury after non-cardiac surgery (MINS) is closely related to increased cardiovascular mortality. AIM: To evaluate the relationship between MINS and interarm systolic blood pressure difference (IASBPD), which has previously been shown to correlate with the frequency of cardiovascular events and arterial arteriosclerotic processes. METHODS: This observational, single-centre cohort study included 240 consecutive noncardiac surgery patients aged ≥ 45 years...

Cardiovascular complications, particularly perioperative myocardial infarction/injury, seem to be major contributors to mortality after noncardiac surgery. With surgical procedures being very frequent (900 000/year in Switzerland), perioperative myocardial injury is common in everyday clinical practice. Over 80% of patients experiencing perioperative myocardial injury do not report symptoms. Therefore perioperative myocardial injury remains undiagnosed and untreated. Moreover, its silent presentation results in limited awareness among both clinicians and the public...

BACKGROUND: Postoperative myocardial injury occurs frequently after noncardiac surgery and is strongly associated with mortality. Intraoperative hypotension (IOH) is hypothesized to be a possible cause. The aim of this study was to determine the association between IOH and postoperative myocardial injury. METHODS: This cohort study included 890 consecutive patients aged 60 yr or older undergoing vascular surgery from two university centers. The occurrence of myocardial injury was assessed by troponin measurements as part of a postoperative care protocol...

OBJECTIVES: To determine whether preoperative endothelial dysfunction provides risk stratification for perioperative renal injury in patients undergoing noncardiac surgery. The relationship between perioperative renal injury and myocardial injury after noncardiac surgery (MINS) was explored secondarily. DESIGN: An observational study. SETTING: Two academic medical centers. PARTICIPANTS: A total of 218 patients scheduled to undergo intermediate or high-risk noncardiac surgery...

BACKGROUND: Intraoperative electrocardiographic monitoring is considered a standard of care. However, there are no evidence-based algorithms for using intraoperative ST segment data to identify patients at high risk for adverse perioperative cardiac events. Therefore, we performed an exploratory study of statistical measures summarizing intraoperative ST segment values determine whether the variability of these measurements was associated with adverse postoperative events. We hypothesized that elevation, depression, and variability of ST segments captured in an anesthesia information management system are associated with postoperative serum troponin elevation...

BACKGROUND: Compelling evidence from large randomized trials demonstrates the salutary effects of statins on primary and secondary protection from adverse cardiovascular events in high-risk populations. Our objective was to investigate the role of perioperative statin therapy in noncardiac vascular and endovascular surgery. METHODS: Electronic information sources were systematically searched to identify studies comparing outcomes after noncardiac surgical or endovascular arterial reconstruction in patients who were and were not taking statin in the perioperative or peri-interventional period...

BACKGROUND: Whether carotid artery stenosis predicts stroke after noncardiac surgery remains unknown. We therefore tested the primary hypothesis that degree of carotid artery stenosis is associated with in-hospital stroke or 30-day all-cause mortality after noncardiac surgery. As carotid artery stenosis is also a marker for cardiovascular disease, our secondary hypothesis was that degree of carotid artery stenosis is associated with postoperative myocardial injury. METHODS: We included adults who had noncardiac, noncarotid surgery at Cleveland Clinic from 2007 to 2011 and had carotid duplex ultrasound performed either within 6 months before or 1 month after surgery...

PURPOSE OF REVIEW: Recent investigations have substantially improved our understanding of myocardial injury after noncardiac surgery (MINS). RECENT FINDINGS: MINS is defined as a prognostically relevant myocardial injury due to ischemia that occurs during or within 30 days after noncardiac surgery. MINS occurs in 8% of adults undergoing major noncardiac surgery and is diagnosed with an elevated postoperative troponin measurement. MINS is associated with significant morbidity, and approximately 10% of patients experiencing MINS will die within 30 days...

PURPOSE OF REVIEW: To review the current evidence for detection and management of perioperative myocardial ischemia. RECENT FINDINGS: Patients who sustain a myocardial injury after noncardiac surgery are predominantly asymptomatic. Myocardial injury after noncardiac surgery is associated with both short-term and long-term mortality. Mortality from both cardiac and noncardiac causes is significant. SUMMARY: Perioperative physicians should refrain from the use of nonsurgical diagnostic criteria for myocardial infarction and adopt the clinical entity known as myocardial injury after noncardiac surgery in order to allow for better determination of the prevalence of this perioperative complication...
