ABSTRACT
Background In a young healthy patient, acute cardiogenic shock with a dilated, thickened left ventricle is strongly suggestive of acute myocarditis. Case SM is a 33 year-old healthy man who presented with decompensated heart failure with severe hypervolemia. Notably, he was exposed to Hand-Foot-Mouth disease (HFMD) two weeks prior. B-type natriuretic peptide was elevated at 3,417 pg/mL (normal range < 50 pg/mL), and troponin was elevated. Echocardiogram revealed dilated, severe systolic dysfunction with thickened left ventricular walls. He progressed to cardiogenic shock and multi-organ failure. Right heart catheterization revealed significantly reduced cardiac output and index of 2.36 and 1.2, respectively. His course was complicated by left ventricular thrombus and subacute embolic stroke, acute renal failure and liver failure. He was treated with afterload reduction, inotropes, and diuresis. His shock resolved, and he improved with medical therapy for cardiomyopathy. Decision-making The clinical course is consistent with acute myocarditis leading to cardiogenic shock with multi-organ failure. A broad differential was considered, including viral etiologies, autoimmune diseases, vasculitis, and toxin-mediated myocarditis. Viral labs including COVID-19 and influenza, as well as HIV, and hepatitis B and C viruses were negative. Coxsackie B2 antibody was positive at 1:80, which is consistent with past or current infection. Rheumatology evaluation was unrevealing, and vasculitis was deemed unlikely given normal inflammatory markers. Urine drug screen was unrevealing. However, adrenergic myocarditis remained on the differential given an adrenal nodule noted on imaging. Plasma free metanephrines were significantly elevated, consistent with pheochromocytoma. Conclusion This is a case of acute myocarditis with two likely etiologies. The patient's presentation correlates temporally with exposure to HFMD, suggesting viral myocarditis. However, he had gross hypervolemia and diuresed 50 pounds, which suggests a more indolent course. We propose that he had adrenergic myocarditis and undetected cardiomyopathy which was exacerbated by a second insult, the Coxsackie virus.Copyright © 2023 American College of Cardiology Foundation
ABSTRACT
Background: The mRNA COVID vaccine is a rare cause of myocarditis in young patients. We describe a case of cardiogenic shock with extensive workup ruling out COVID vaccine induced myocarditis. Case: 42-year-old female who drinks 5 Monster energy drinks and 3-4 cups of coffee daily presented to the hospital with palpitations two weeks following her mRNA COVID vaccine. EKG showed atrial tachycardia with heart rates of 160 beats per minute. Adenosine and Lopressor were administered resulting in hemodynamic instability requiring norepinephrine. An echocardiogram showed dilated cardiomyopathy with ejection fraction of 15%. Right heart catheterization was performed, and the cardiac index was 1.22 L/min/m², systemic vascular resistance was 1918 dynes*sec*cm-5 and wedge pressure was 31 mm Hg. The patient was started on nitroprusside, furosemide, and milrinone drips and she began to improve. The patient was adamant the vaccine is what triggered her heart failure and extensive testing was performed to rule out COVID vaccine induced myocarditis. Workup showed normal coronary arteries and no evidence of infiltrative disease or myocarditis on cardiac MRI. The etiology was from tachycardia induced cardiomyopathy triggered by excessive stimulants and the patient had successful atrial tachycardia ablation of the right superior pulmonary vein. She was discharged on medical therapy for heart failure and advised to stop drinking energy drinks. Decision-making: Once the patient did not respond to the rate controlling agents an echocardiogram showed reduced ejection fraction. Right heart catheterization confirmed cardiogenic shock and nitroprusside and milrinone were started to help reduce afterload and improve contractility. Workup to exclude COVID induced myocarditis lead to the diagnosis of tachycardia induced cardiomyopathy and atrial tachycardia ablation was performed. Conclusion: We report a case of cardiogenic shock with workup diagnosing tachycardia induced cardiomyopathy induced from a combination of excessive monster energy drinks and coffee. She was treated successfully with afterload reduction, inotrope support, and atrial tachycardia ablation.
ABSTRACT
Background: In order to counter and control the spread of the new COVID-19 pandemic, at the beginning of March 2020, the Romanian government decided to apply strict isolation and quarantine measures. Objective: In the present study, we aimed to analyze the impact of the COVID-19 pandemic and isolation/quarantine at home on lifestyle and daily diet, and to identify changes caused by the pandemic related to the nutritional status and food preferences of the Romanian population. Material and Method: We conducted a prospective observational study based on a structured questionnaire that included 30 items for investigating multiple aspects regarding the dietary habits in the context of the pandemic, quarantine and social isolation imposed by the new SARS-CoV-2 coronavirus. The questionnaire was disseminated on various online platforms accessible from any device with an internet connection in Romania, on social media groups between January and March 2021. The questionnaire was made online, using the Google Forms platform, this method being very useful for carrying out the proposed evaluation, as it facilitated the national dissemination of the evaluation questionnaire. The final study group consisted of 620 respondents from 35 counties of Romania. Results: Regarding weight status, we found that the respondents showed significantly more frequent weight fluctuations during the pandemic than before (p <0.0001). The results showed an increase in the mean weight of the respondents during the pandemic vs. their mean weight before (p = 0.04). In contrast, there were no statistically significant differences between the BMI calculated before and during the pandemic (p = 0.3). Respondents, who had a chaotic diet (40.64%) before the pandemic, became significantly more organized in this regard during the pandemic (35.96%) (p = 0.008). Conclusions: We can state that the pandemic period and isolation at home analyzed in terms of eating habits had positive consequences for about half of the study participants which adopted an organized, diversified eating behavior and balanced lifestyle.
