Unusual electrocardiographic changes during acute pancreatitis

Assessment of frontal QRS-T angle in distinguishing mild and severe acute pancreatitis in emergency department: A retrospective study

Acute pancreatitis (AP) is a disease that poses significant health risks with potential severe outcomes. Identifying markers for severity can aid in early intervention and improve prognoses. This study, conducted in the emergency department, investigates the QRS-T angle as a potential indicator of severity in patients with acute pancreatitis. This retrospective study included 367 patients diagnosed with AP, classified as either mild acute pancreatitis or severe acute pancreatitis based on Ranson criteria. The QRS-T angle was measured using standard 12-lead electrocardiogram, and the data were analyzed to compare the QRS-T angles between the mild acute pancreatitis and severe acute pancreatitis groups. This research adhered to the guidelines outlined in the Strengthening the Reporting of Observational Studies in Epidemiology statement. The study included 367 patients, 94% (n = 345) had mild pancreatitis while 6% (n = 22) had severe pancreatitis. Severe cases had a significantly higher median age (P < .001) and higher rates of hypertension and diabetes mellitus (P = .027, P = .011). Severe cases also had higher Ranson scores (3 [IQR 3-3.25] vs 1 [IQR 1-2], P < .001) and longer hospital stays (6 [IQR 2.75-11.5] days vs 3 [2-5] days, P = .029). Additionally, severe pancreatitis group showed higher QRS-T angle (P < .001), higher rates of abnormal QRS angles (31.8% vs 10.1%, P = .002), and QRS-T angles (31.8% vs 8.1%, P < .001). The QRS-T angle may serve as a valuable clinical tool for differentiating between mild and severe forms of acute pancreatitis. This could potentially help clinicians in stratifying patients according to their risk and tailoring their management accordingly.

Necrotizing acute pancreatitis with electrocardiogram changes masquerading acute coronary syndrome

Acute pancreatitis (AP) refers to the acute inflammation of the pancreas; however, if there is concurrent necrosis, it is called necrotizing acute pancreatitis (NAP). The diagnosis is sometimes difficult because it might mimic acute coronary syndrome (ACS). We report a case of a 28-year-old male, who presented to the emergency department (ED) with severe epigastric pain, shortness of breath and diaphoresis for 4-5 h. The initial electrocardiogram (ECG) showed marked sinus bradycardia with an incomplete left bundle branch block. Considering the clinical presentation and ECG changes, he was managed as ACS and was rushed to catheterization laboratory for a coronary angiogram, which was reported normal. Subsequently, his serum pancreatic enzymes were elevated, and computed tomography of the abdomen showed NAP. In ED settings, it is difficult to differentiate between the two, particularly when AP presents with ECG manifestations masquerading as ACS.

Cardiac depression in severe acute pancreatitis: development mechanisms and possible treatment approaches. Review

Cardiac depression, also known as myocardial depression, is one of the typical complications of severe acute pancreatitis. The review describes modern views on the mechanism of development of this phenomenon; the place of the term «myocardial depression factor» at the current stage of study of the problem was discussed; pathogenetic factors of myocardial depression requiring further study have been identified. An attempt to consider cardiac depression as a phenomenon involving the whole cardiovascular system, rather than the heart along, was made. Each pathophysiological factor is examined in terms of the possibility of clinical use.

Recommendation for Inclusion of Surface Echocardiography in Evaluation of Chest Pain in Acute Emergency Care

Objective  A significant number of conditions may mimic acute myocardial infarction when patients present to acute emergency care (AEC) with chest pain. A proportion of such patients may exhibit ST segment abnormality on the electrocardiogram (ECG) which is due to conditions other than acute coronary syndromes (ACS) or myocardial infarction. The American Heart Association/American College of Cardiology guidelines (2015) algorithm for ACS does not include echocardiographic evaluation in the assessment of chest pain. Patients with chest pain may be subjected to investigations and interventions based on ECG leading unwarranted invasive procedures, which may prove unnecessary, futile, and even detrimental. This study was performed to determine if a bedside echocardiography would help identify the conditions that do not need intervention and might possibly change the treatment pathway at the right time.

Materials and Methods In a prospective observational study design, adult patients presenting to AEC with chest pain were included in the study. After the assessment of airway, breathing and circulation, and initiation of bed side monitoring, a 12-lead ECG was obtained. Patients exhibiting a significant ST change on ECG were subjected to bedside echocardiography, that is, two-dimensional (2D) transthoracic echocardiography (2D-TTE) with a cross reference to a consultant cardiologist for the precise assessment and diagnosis. The findings of echocardiography were correlated with electrocardiogram for possible diagnostic coronary angiography and percutaneous coronary intervention. The results of ECG, echocardiography, and coronary angiography (if done) were analyzed to determine the sensitivity and specificity of echocardiography for ACS.

Results Among 385 patients in the study, 312 were suspected to suffer acute coronary syndrome; among these patients, eight patients turned out to have chest pain due to non-ACS. Of the 73 patients, the chest pain was suspected to be not of cardiac ischemia origin; among these patients, 66 patients were true negative and 7 patients were false positive. Echocardiography was the predictive of ischemic chest pain with a predictive value of 97.7%. The specificity of echocardiography calculated from the above confusion matrix was 90.4% and sensitivity was 97.4%. The positive predictive value of 2D-TTE was 97.7% and negative predictive value was 89.1%. The overall accuracy of bedside 2D-TTE was 96.1%.

Conclusion Echocardiography was found to be an effective tool in aiding diagnosis of a patient presenting to AEC with chest pain and ST-T changes in ECG. A significant percentage of patients (18.7%) presented to AEC with chest pain, ST-T changes and found to have causes other than ACS, and screening echocardiography (2D-TTE) was able to identify 90.4% of those cases. From this study, we conclude that bedside echocardiography had high specificity (90.4%) and sensitivity (97.43%) in identifying regional wall motion abnormality due to ACS. Hence, bedside echocardiography is recommended in patients with chest pain and ST-segment abnormality to avoid unnecessary delay in diagnosis and invasive interventions in non-ACS.

Acute Pancreatitis Masquerading as Inferior Wall Myocardial Infarction: A Review

A rare presentation of acute pancreatitis is with electrocardiographic (ECG) changes that mimic myocardial ischemia. We present a report of a patient that presented with hemodynamic instability and new ECG changes of ST segment elevations in contiguous leads II, III, and aVF mimicking an inferior wall myocardial infarction. Emergent coronary angiography showed no significant coronary obstruction, but it was followed by a left-sided hemiplegia with radiographic evidence of diffuse embolic stroke. The patient was later found to have an underlying diagnosis of pancreatitis. Additional history that later became available indicated a history of severe acute pancreatitis treated elsewhere a few months prior to the current admission. We present the first comprehensive review of the literature comprising 36 total cases with pancreatitis masquerading as acute myocardial infarction, with inferior wall STEMI pattern being the most frequent. We present this case to highlight the diagnostic dilemma posed by this masquerade of a high acuity myocardial infarction and to highlight alternative diagnoses to be considered in such clinical circumstances.
