Cardiopulmonary Exercise Test in the Detection of Unexplained Post-COVID-19 Dyspnea


Posted: 2021-09-21 19:00:00
There is emerging evidence of prolonged recovery in survivors of coronavirus disease 2019 (COVID-19), even in those with mild COVID-19. In this paper, we report a case of a 39-year-old male with excessive body weight and a history of borderline values of arterial hypertension without therapy, who was mainly complaining of progressive dyspnea after being diagnosed with mild COVID-19. According to the recent guidelines on the holistic assessment and management of patients who had COVID-19, all preferred diagnostic procedures, including multidetector computed tomography (CT), CT pulmonary angiogram, and echocardiography, should be conducted. However, in our patient, no underlying cardiopulmonary disorder has been established. Therefore, considering all additional symptoms our patient had beyond dyspnea, our initial differential diagnosis included anxiety-related dysfunctional breathing. However, psychiatric evaluation revealed that our patient had only a mild anxiety level, which was unlikely to provoke somatic complaints. We decided to perform further investigations considering that cardiopulmonary exercise test (CPET) represents a reliable diagnostic tool for patients with unexplained dyspnea. Finally, the CPET elucidated the diastolic dysfunction of the left ventricle, which was the most probable cause of progressive dyspnea in our patient. We suggested that, based on uncontrolled cardiovascular risk factors our patient had, COVID-19 triggered a subclinical form of heart failure (HF) with preserved ejection fraction (HFpEF) to become clinically manifest. Recently, the new onset, exacerbation, or transition from subclinical to clinical HFpEF has been associated with COVID-19. Therefore, in addition to the present literature, our case should warn physicians on HFpEF among survivors of COVID-19. Keywords: Anxiety; Dysfunctional breathing; Heart failure; SARS-CoV-2.

感染症の炎症反応からメタボリックシンドロームの人を保護できるかもしれない2種類のペプチドが開発された

バンダービルト大学医療センター(VUMC)の研究者らが開発した細胞貫通ペプチドは、細菌やウイルスの感染によって生じ、しばしば致命的となる敗血症性ショックを動物モデルで予防することができたことが報告された。この研究成果は、2021年6月7日にScientific Reports誌のオンライン版に掲載され、COVID-19を含む微生物感染に対する制御不能な炎症反応による重篤な合併症や死亡のリスクが最も高い患者を保護する方法につなる可能性がある。…
