Insights
Mild COVID-19 (coronavirus disease 2019) can lead to serious cardiac issues and blood clots. This case highlights the need for further research into post-COVID-19 thrombophilia and prophylaxis strategies.
Area of Science:
- Cardiology
- Infectious Diseases
- Neurology
Background:
- COVID-19 (coronavirus disease 2019) is a global pandemic associated with significant morbidity and mortality.
- Myocardial injury and thromboembolism are recognized complications in severe COVID-19.
- The risks of these complications in asymptomatic or mild COVID-19 cases remain largely unknown.
Observation:
- A 35-year-old man with no prior cardiac history presented with chest pain and elevated troponin levels.
- He had a history of mild, unspecified viral illness one month prior, later testing positive for SARS-CoV-2 antibodies.
- Diagnostic workup revealed new cardiomyopathy, left ventricular thrombus, and coronary artery thrombosis, followed by a middle cerebral artery stroke.
Findings:
- The patient experienced multiple thromboembolic events, including coronary artery and cerebral artery thrombosis, following a mild COVID-19 infection.
- Cardiac evaluation demonstrated new-onset cardiomyopathy and thrombus formation.
- Despite initial treatment, a second arterial thromboembolic event (stroke) occurred prior to discharge.
Implications:
- Mild COVID-19 can precipitate significant cardiac injury and coagulopathy, even in young individuals without prior health conditions.
- This case underscores the need for further investigation into the duration of thrombophilia post-COVID-19 recovery.
- Guidelines are needed for thromboprophylaxis in specific populations and for determining the optimal duration of therapy after COVID-19.
Background:
COVID-19 has spread worldwide and has caused significant morbidity and mortality. Myocardial injury and thrombo-embolism are known complications for those with severe forms of disease. The incidence and risk factors for these complications for those patients who are asymptomatic or with mild forms of COVID-19 is unknown.
Case Summary:
In this report we describe the case of a 35-year-old man with no past cardiac history who presented with chest pain and a high-sensitivity troponin level of 386 ng/L in the context of an unspecified mild viral illness 1 month previously. Diagnostic evaluation revealed a new cardiomyopathy, left ventricular thrombus, and mid right coronary artery thrombosis. The coronary thrombosis was treated with thrombectomy. SARS-CoV-2 antibodies returned positive. He initially did well post-procedure; however, prior to discharge, he developed a second arterial thrombo-embolism event, a middle cerebral artery stroke. He was treated with thrombectomy and remains hospitalized.
Discussion:
Recognition that mild COVID-19 can be complicated by subsequent cardiac injury and/or coagulopathy is important. As more people recover from this viral illness and return to normal activity levels, discussion among cardiac experts has begun regarding screening for occult myocardial injury in those who plan to resume competitive athletic activity. This case highlights the need for investigation regarding (i) the duration of thrombophilia after recovery from illness; (ii) the population that should receive thromboprophylaxis; and (iii) the duration of thromboprophylaxis therapy for COVID-19.
