One-Year Long-Term Follow up for Post-Acute Sequelae of Covid-19 Pots Patients

Background: Persistence of orthostatic tachycardia, palpitations, and fatigue beyond 4 weeks of an acute COVID-19 infection has been termed Post-Acute Sequelae of COVID-19 (PASC) POTS. We have previously reported 6-month outcomes of PASC POTS. Long-term management and outcomes of these patients is unknown. Objective(s): To examine the long-term management and outcomes of PASC POTS patients. Method(s): We conducted a retrospective study of all patients who were diagnosed with POTS at Cardiology, Neurology, and Rehabilitation Post-COVID clinic after a COVID-19 infection between March 1, 2020, and November 1, 2022, at the University of Texas Health San Antonio. We examined COVID history, POTS diagnosis, management, and one-year outcomes of post-COVID POTS patients. Result(s): In 42 patients that were diagnosed with PASC POTS, 33 had a one-year follow-up. 100% were female, 60.6% were Caucasian. Average age was 40.6 + 11 years while the average BMI was 31.9 + 10.4 kg/m2. The most common symptoms were fatigue (87.9%), palpitations (75.7%), brain fog (72.7%), orthostatic tachycardia, exercise intolerance, and dyspnea (70%). The mean heart rate change with 10-minute standing test was 42.68 + 26.73 beats per minute. At 12-months follow-up, the most common symptom was still fatigue (66.7%), palpitations (45.5%), orthostatic tachycardia, and orthostatic intolerance (42.4%). All patients were managed with increased salt and fluid intake, lower compression stockings and rehabilitation. Fifty five percent of patients were treated with Enhanced External Counter Pulsation (EECP), 42% were treated with beta blockers, 18% with fludrocortisone, 15% with midodrine, and 15% with Pyridostigmine. At 1 year follow-up, 33% of patients reported improvement in their symptoms, 33% reported worsening of symptoms, 24% reported stable symptoms, and 9% had resolution. Conclusion(s): PASC POTS patients continue to experience adverse symptoms even at one year. Physical therapy and rehabilitation and pharmacological therapy appear improve symptoms in a minority of patients.Copyright © 2023

Impact of the COVID-19 pandemic on cardiovascular heart disease medication use: time-series analysis of England's prescription data during the COVID-19 pandemic (January 2019 to October 2020).

BACKGROUND: Management of high blood pressure (BP) typically requires adherence to medication regimes. However, it is known that the COVID-19 pandemic both interrupted access to some routine prescriptions and changed some patient health behaviours. AIM: This study, therefore, retrospectively investigated prescription reimbursement of cardiovascular (CVD) medicines as a proxy measure for patient adherence and access to medicines during the pandemic. METHODS: A cohort study of all primary care patients in England prescribed CVD medicines. The exposure was to the global pandemic. Prescriptions were compared before and after the pandemic's onset. Statistical variation was the outcome of interest. RESULTS: Descriptive statistics show changes to monthly prescriptions, with wide confidence intervals indicating varying underlying practice. Analysis of variance reveals statistically significant differences for bendroflumethiazide, potassium-sparing diuretics, nicorandil, ezetimibe, ivabradine, ranolazine, colesevelam and midodrine. After the pandemic began (March-October 2020), negative parameters are observed for ACE inhibitors, beta-blockers, calcium channel blockers, statins, antiplatelet, antithrombotics, ARBs, loop diuretics, doxazosin, bendroflumethiazide, nitrates and indapamide, indicating decelerating monthly prescription items (statistically significant declines of calcium channel blockers, antithrombotic, adrenoreceptor blockers and diuretics) of CVD medicines within the general population. Many data points are not statistically significant, but fluctuations remain clinically important for the large population of patients taking these medications. CONCLUSION: A concerning decline in uptake of CVD therapies for chronic heart disease was observed. Accessible screening and treatment alongside financial relief on prescription levies are needed.

THE UNPREDICTABILITY OF LABILE BP: AFFERENT BAROREFLEX FAILURE IN A CRITICAL PATIENT WITH MULTIPLE THYROID SURGERIES AND COVID-19 INFECTION

SESSION TITLE: Cardiovascular Critical Care Cases SESSION TYPE: Rapid Fire Case Reports PRESENTED ON: 10/19/2022 12:45 pm - 1:45 pm INTRODUCTION: The carotid sinus-arterial baroreflex is essential in maintaining blood pressure (BP) regulation. Afferent baroreflex failure (ABF) can present with labile changes in BP within seconds and can be secondary to neck surgery or radiation (RT). The prevalence and etiology of this condition remain unknown, and management of BP can be challenging. We present here the first case, to our knowledge, of ABF precipitated by thyroidectomy, in a patient (pt) with active COVID-19 pneumonia (PNA), causing difficult control of severely labile BP in a critical care unit. CASE PRESENTATION: A 74-year-old female with a history of COPD and a thyroid mass s/p an open left hemithyroidectomy & isthmusectomy, partial right thyroidectomy with drain placement who presented with dyspnea and hypoxia with COVID-19 PNA and superimposed bacterial PNA. She was immediately intubated and admitted to the ICU. Due to improved alertness and breathing, an extubation trial was done on day 2 but was unsuccessful due to a neck mass compressing the trachea, and during extubation, the pt began to develop stridor, desaturate, and was reintubated. CT head and neck showed a markedly enlarged thyroid with left tracheal deviation and the pt underwent complete thyroidectomy the following day. On the 4th day following surgery, the pt desaturated on PRVC and CXR showed new consolidation, and the PNA panel was positive for K. pneumoniae. The pt's BP began to fluctuate from the 80's/40's - 260's/190's. Titrating pressors were not effective in controlling her volatile BP. Clonidine was started to control hypertensive urgencies, but severe subsequent hypotensive episodes made it difficult to continue. A trial of Fentanyl drip did not add a benefit either. Adequate BP control was finally achieved through administering Clonidine only when SBP reached above 180mmHg and Midodrine when SBP reached below 80mmHg. DISCUSSION: Blood pressure changes can be sensed by carotid sinus stretch receptors. ABF can manifest secondary to carotid sinus nerve damage following neck surgery or radiation. The diagnosis of ABF remains ill-defined;with limited research available to guide definitive management. Critically ill patients with poor prognosis have demonstrated higher ACTH levels with a longer cortisol release, with elevated IL-8 and IL-6 concentrations, concluding potential destructive pituitary-adrenal axis response in the setting of inflammation. IL-6 in particular can manifest following hypoxic conditions. In certain cases of POTS and AD in COVID-19, there has been an improvement of symptoms with the use of B-blockers, fludrocortisone, midodrine, methyldopa, and clonidine. CONCLUSIONS: Additional research with a multidisciplinary approach is warranted to fully optimize the treatment of ABF in patients with neck surgery and or inflammatory conditions such as COVID-19.

COVID-19-INDUCED POSTURAL ORTHOSTATIC TACHYCARDIA SYNDROME

SESSION TITLE: Extraordinary Cardiovascular Reports SESSION TYPE: Rapid Fire Case Reports PRESENTED ON: 10/18/2022 01:35 pm - 02:35 pm INTRODUCTION: Postural orthostatic tachycardia syndrome (POTS) is one of the most common autonomic disorders (1). POTS is diagnosed by increasing heart rate by 30 bpm on more, within the first 10 minutes of standing, without orthostatic hypotension (2). Associated debilitating symptoms are lightheadedness, fainting, tremor, orthostatic intolerance, and tachycardia (2). Viral infections such as HIV, hepatitis C, mumps, Epstein bar virus, and influenza have been commonly reported with POTS syndrome (3 ). We are presenting a rare case of COVID-19 induced POTS. CASE PRESENTATION: 38-year-old presented to the hospital with the chief complaint of shortness of breath chest tightness. Her past medical history was significant for COVID-19 infection two weeks before presentation. On arrival patient's vitals were within normal limits. Her physical examination was unremarkable. Laboratory investigations, including complete blood count, thyroid function test, and comprehensive metabolic profile, were unremarkable. Chest x-ray, CT angiogram, and echocardiogram were unremarkable for any consolidation, pulmonary embolism, and congestive heart failure. Orthostatic vitals were obtained, showing that the patient's heart rate increased from 90 beats/minute to 140 beats/minute, from supine to standing. This patient was diagnosed with COVID-19 induced POTS, given she was meeting the criteria of POTS and no other reason was found for postural orthostatic tachycardia. She was managed conservatively with hydration, and the patient was also instructed about yoga therapy. She was discharged home with a cardiology follow-up. DISCUSSION: COVID-19 induced POTS is a relatively new entity that most commonly affect female, and the estimated prevalence is around is 17 per 100,000 patients (3). It has been reported that 10% of the patient who tests positive for COVID-19 infection remains unwell beyond three weeks after recovery from the infection (2). For some of those patients, POTS may be the cause of their symptoms. The exact pathophysiology for COVID-19 induced POTS is poorly understood and may includes peripheral neuropathy, baroreceptor dysfunction, hypovolemia, and increased serum norepinephrine (2). Nonpharmacological treatment includes increasing fluid consumption of 2 to 3 L of water per day, lower limb compression stockings, and regular exercise (2). The commonly off-label pharmacological treatment include ivabradine, fludrocortisone, midodrine, and beta-blockers (2). CONCLUSIONS: POTS is a new and under-recognized entity. The clinician should have a high suspicion of POTS syndrome in a patient with a history of recent or remote COVID-19 infection presenting with orthostatic symptoms. Timely diagnosis is essential to prevent the morbidity associated with debilitating symptoms. Reference #1: Blitshteyn S & Whitelaw S.

Review of Integrative Therapies for Management of Post-COVID Dysautonomia

Methods: We reviewed reports of post COVID dysautonomia and management strategies pursued to understand best practices and provide a primer for clinicians to guide patient management. We reviewed the literature for case reports of post COVID dysautonomia and compiled the cases into a table. Treatment approaches and outcomes were aggregated into an algorithm for management guidance. Results: Ten studies regarding post COVID dysautonomia were reviewed. Strategies included conservative approaches such as fluids, salt consumption, compression stockings, abdominal binders and head of bed elevation as well as strength building such as yoga, resistance exercise, and recumbent physical activity. Moreover, psychosocial support including cognitive behavioral therapy, biofeedback, and support groups were emphasized along with pharmacologic remedies such as midodrine, ivabradine, fludrocortisone, intravenous immunoglobulin, gabapentin, and topical lidocaine in additoin to interventions such as enhanced external counterpulsation. Primary and secondary outcomes included self-report surveys, autonomic laboratory testing, hand grip strength and heart rate variability. Background: Growing numbers of cases of dysautonomia after acute COVID-19 infection are being reported involving previously healthy patients. This post-COVID dysautonomia is predominantly characterized by lingering neurologic and cardiovascular dysfunction including tachycardia, orthostatic intolerance, migraine, exercise intolerance, fatigue, and cognitive impairment. Anxiety, insomnia, and uncertainty surrounding the COVID-19 pandemic present additional risk factors for sympathetic overdrive and deconditioning. Best management strategies and practice guidelines for this patient population remains unknown. Conclusion: Our review suggests consideration of an integrative, multimodal treatment approach involving physical activity, mental well-being, nutrition, stress management, and medication. These primarily facilitate management of dysautonomia, but rarely lead to complete symptom resolution. Despite the uncertainty associated with post-COVID dysautonomia, patient validation, education, and lifestyle approaches provide the cornerstone of management. Since post-COVID dysautonomia will comprise an increasing number of care consultations, clinician awareness, prompt diagnosis, and personalized management are essential.

Putting midodrine on the MAP: An approach to liberation from intravenous vasopressors in vasodilatory shock.

PURPOSE: Prolonged duration of intravenous (IV) vasopressor dependence in critically ill adult patients with vasodilatory shock results in increased length of stay in both the intensive care unit (ICU) and hospital, translating to higher risk of infection, delirium, immobility, and cost. Acceleration of vasopressor liberation can aid in reducing these risks. Midodrine is an oral α 1-adrenergic receptor agonist that offers a potential means of liberating patients from IV vasopressor therapy. This clinical review summarizes primary literature and proposes a clinical application for midodrine in the recovery phase of vasodilatory shock. SUMMARY: Five studies with a total of over 1,000 patients conducted between 2011 and 2021 were identified. In observational studies, midodrine administration was demonstrated to lead to faster time to liberation from IV vasopressor therapy and shorter ICU length of stay in patients recovering from vasodilatory shock. These findings were not replicated in a prospective, multicenter, randomized controlled trial. In this review, literature evaluating midodrine use for IV vasopressor liberation is summarized and study limitations are discussed. CONCLUSION: On the basis of this review of current literature, recommendations are provided on selecting appropriate candidates for adjunctive midodrine in the recovery phase of vasodilatory shock and considerations are discussed for safely and effectively initiating, titrating, and discontinuing therapy.
