Objective. Acute mesenteric ischemia (AMI) is a rare but serious complication after cardiac surgery. The aim of this retrospective study was to evaluate the incidence, outcome, and perioperative risk factors of AMI in the patients undergoing elective cardiac surgery. Methods. From January 2005 to May 2013, all patients who underwent cardiac surgery were screened for participation, and patients with registered gastrointestinal complications were retrospectively reviewed. Univariate analyses were performed. Results. The study included 6013 patients, of which 52 (0.86%) patients suffered from AMI, 35 (67%) of whom died. The control group (150 patients) was randomly chosen from among cases undergoing cardiopulmonary bypass (CPB). Preoperative parameters including age (P = 0.03), renal insufficiency (P = 0.004), peripheral vascular disease (P = 0.04), preoperative inotropic support (P < 0.001), poor left ventricular ejection fraction (P = 0.002), cardiogenic shock (P = 0.003), and preoperative intra-aortic balloon pump (IABP) support (P = 0.05) revealed significantly higher levels in the AMI group. Among intra- and postoperative parameters, CPB time (P < 0.001), dialysis (P = 0.04), inotropic support (P = 0.007), prolonged ventilator time (P < 0.001), and IABP support (P = 0.007) appeared significantly higher in the AMI group than the control group. Conclusions. Prompt diagnosis and early treatment should be initiated as early as possible in any patient suspected of AMI, leading to dramatic reduction in the mortality rate.
Metabolic syndrome is a well-known cardiovascular risk factor closely related to increased insulin resistance. This study assessed the effects of metabolic syndrome on early post-operative mortality and morbidity in 100 coronary artery bypass graft (CABG) patients: 50 patients with and 50 without metabolic syndrome. A total of 17 patients were excluded from the analysis as they did not attend follow-up, leaving 51 males (61.4%) and 32 (38.6%) females of mean +/- SD age 60.02 +/- 9.76 years for analysis. Diabetes, hypertension and a high body mass index were significantly more common in patients with metabolic syndrome. A statistically significant relationship was found between metabolic syndrome and surgical wound infection. Non-significant positive correlations were found between metabolic syndrome and post-operative atrial fibrillation, surgical revision due to haemorrhage, ventricular tachycardia and ventricular fibrillation, and prolonged intubation. In conclusion, metabolic syndrome did not affect mortality, but did increase the risk of post-operative surgical wound infection.
Patients presenting to the emergency department with chest pain are evaluated by emergency physicians in hospitals without cardiology cover 24 h a day. The purpose of this study is to determine the consistency of electrocardiography (ECG) interpretation and chest pain likelihood classification between emergency physicians and cardiologists. This randomised prospective cross-sectional study was performed in a tertiary care university hospital emergency department. The study form included ECG interpretation and chest pain likelihood classification according to American College of Cardiology (ACC)/American Heart Association (AHA) guideline which were recorded by emergency physicians and cardiologists separately in a blinded fashion. All chest pain patients who consulted with a cardiologist were enrolled into the study during the study period. The consistency between the two groups and the kappa value were calculated. Recorded study forms of 133 patients with cardiology consultations were evaluated. The consistency in the interpretation of ECG between the emergency physicians and cardiologists was found to be 94.6% (kappa = 0.85) for ST segment elevation, 78.6% (kappa = 0.57) for ischaemic ECG findings and 79.3% (kappa = 0.36) for dynamic ECG changes. The consistency for the likelihood classification between two groups for predicting the pain as angina or non-cardiac was 90.8% (kappa = 0.30), for classifying as acute coronary syndrome or stable angina pectoris (SAP) was 95.6% (kappa = 0.26) and for classifying patients as low likelihood or intermediate-high likelihood was 86.3% (kappa = 0.61). A strong consistency was shown between the emergency physicians' and cardiologists' ECG interpretation especially in determining the ST segment elevation. And also, there is a strong concordance in the likelihood classification of chest pain patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
