Acute pericarditis

Acute Viral Pericarditis Complicated by Cardiac Tamponade as a Result of COVID-19

Severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) and coronavirus disease 2019 (COVID-19) predominantly cause respiratory symptoms but cardiovascular complications from COVID-19 have been documented in the literature. Acute pericarditis has been known to be caused by COVID-19 but severe cardiac complications, such as cardiac tamponade, have rarely been reported. Early diagnosis and treatment with pericardiocentesis are imperative, as this can improve patient outcomes. A 56-year-old female presented with chest pain and recurrent episodes of presyncope. The patient tested positive for SARS-Cov-2 through a polymerase chain reaction (PCR) test. The patient was hypotensive on arrival and the initial workup with electrocardiogram was significant for sinus tachycardia with low voltage QRS complexes in the precordial and limb leads. A transthoracic echocardiogram was also done and showed a large circumferential pericardial effusion with chamber collapse of the right atrium and right ventricle during diastole indicative of tamponade physiology. The patient's clinical course was complicated by pulseless electrical activity cardiac arrest during which a pericardiocentesis was done. One hundred (100) mL of serous pericardial fluid was drained and a return of spontaneous circulation was obtained after roughly 10 minutes of cardiopulmonary resuscitation. Further infectious and noninfectious workups, including malignant and rheumatologic etiologies for acute pericarditis, were negative. The patient was subsequently treated with high-dose non-steroidal anti-inflammatory drugs (NSAIDs) and colchicine for viral pericarditis. The patient's clinical course improved, and the patient was subsequently discharged after a prolonged hospital course to a subacute rehabilitation facility to undergo physical therapy.

Treatment with Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) Does Not Affect Outcome in Patients with Acute Myocarditis or Myopericarditis

Background: Previous animal studies reported an association of non-steroidal anti-inflammatory drugs (NSAIDs) with adverse outcomes in acute myocarditis, which is why these drugs are currently not recommended in affected patients. In this retrospective case-control study, we sought to investigate the effects of NSAID treatment in patients with acute myocarditis and myopericarditis to complement the available evidence. Method: A total of 114 patients with acute myocarditis were retrospectively enrolled. Demographical, clinical and laboratory data were extracted from hospital records. Patients who received NSAIDs (n = 39, 34.2%) were compared to controls. Follow-up on all-cause mortality was acquired for two years. Propensity score matching was additionally conducted to account for covariate imbalances between groups. Results: Treatment with NSAIDs was neither associated with a worse outcome (p = 0.115) nor with significant differences in left ventricular systolic function (p = 0.228) or in-hospital complications (p = 0.507). Conclusion: Treatment with NSAIDs was not associated with adverse outcomes in our study cohort. Together with the findings of previous studies, our results indicate that these drugs could be safely administered in patients with myocarditis and myopericarditis.

Acute Pericarditis: Aetiologic Diagnosis and Practical Aspect of the Management

Pericarditis is an uncommon pathology that represents 0.1% of patients hospitalized for chest pain with a wide etiological spectrum and whose cause is uncommonly highlighted. In order to determine the incidence of specific acute microbiological or autoimmune pericarditis and identify subsets of patients with a higher incidence of specific etiologies; and analyze the conformity of the management of acute pericarditis according to the recommendations, a retrospective inclusion of all patients admitted to our hospital from January 2010 to December 2018 with the diagnosis of acute pericarditis was conducted. Data concerning clinical, paraclinical and treatment items were collected. Ninety-nine patients were included. Specific etiologic exams were completely conducted in 63.6% of the patients. There was no link between the decision to conduct etiology exams and the age, gender, a history of acute pericarditis or relapse. There was a trend between an elevated CRP and the realization of the kit. There was a statistically significant link between the achievement of etiologic exams and the presence of severity criteria or the presence of a pericardial effusion. An etiology was found in 52.4%, more frequently microbiological (viral and Mycoplasma pneumoniae). Approximately 85.9% of all patients were hospitalized. Treatment was in accordance with the recommendations in 76.8%. Despite the percentage of microbiological etiologies found, it does not impact the therapeutic strategy. The criteria for hospitalization must be better suited since half of those hospitalized after the european society of cardiology (ESC) 2015 recommendations had no need to be. However, monitoring after discharge is not clearly defined by learned societies.

Spodick’s Sign: A Case Report and Review of Literature

Acute pericarditis is commonly diagnosed in patients who present with chest pain. Accurate diagnosis of acute pericarditis is essential because of its relative similarity to ST-elevation myocardial infarction (STEMI) in both clinical presentation and electrocardiogram (EKG) changes. Additionally, troponin elevation is occasionally seen in acute pericarditis due to myocardial involvement (myopericarditis), which makes accurate diagnosis more challenging. A 12-lead EKG remains the most useful diagnostic test in differentiating acute pericarditis from STEMI. Spodick's sign is a less recognized electrocardiographic feature of acute pericarditis and is frequently overlooked by clinicians. We present a case of a 52-year-old male who initially presented with acute onset substernal chest pain. His EKG revealed diffuse subtle ST elevation and downsloping TP segment (Spodick's sign). A coronary angiogram demonstrated normal coronaries which eliminated the possibility of coronary artery disease. In this article, we will discuss how to differentiate between acute pericarditis and myocardial infarction, with a focus on Spodick's sign, amongst other EKG findings suggestive of pericarditis.

Falciparum malaria mimicking acute myocardial infarction

Severe malaria is a concerning problem in developing country and is mostly due to Plasmodium Falciparum. Common organs involved are liver, central nervous system, lungs, kidneys, and vasculature. Cardiac involvement is very rare and is mostly underestimated. Cardiac involvement occurs in the form of myocardial dysfunction, arrhythmia, and ventricular systolic dysfunction. This is the rare case of acute pericarditis due to plasmodium falciparum mimicking as inferolateral ST elevation myocardial infarction (STEMI) due to suggestive electrocardiography (ECG) findings.
