OBJECTIVE: Pulmonary embolism as a potential complication that may occur late in the course of COVID-19 cases. The aim of our study is to evaluate the frequency of pulmonary embolism in patients with new or ongoing dyspnea after a COVID-19 infection.

PATIENTS AND METHODS: This is a single-center, prospective observational study to evaluate the clinical and radiological outcomes of consecutive patients presenting outpatient clinic diseases to the chest and a new or ongoing dyspnea after a COVID-19 infection. Demographic, clinical and laboratory data were collected. Dyspnea was evaluated according to the New York Heart Association (NYHA) classification.

RESULTS: Pulmonary embolism was detected in 23.8% (25/105) of patients with new or ongoing dyspnea after a COVID-19 infection. Proportion of pulmonary embolism in patients with NYHA classes I, II, III and IV were respectively 8.7%, 20.0%, 30.0% and 35.3% (p for trend=0.02). Compared to NYHA class I and II patients with dyspnea, those in NYHA classes III and IV showed a higher rate of pulmonary embolism [31.6% vs. 14.6%, OR: 2.7 (1.0 to 7.1), p=0.04, respectively]. In Logistic Procedures, NYHA classes of dyspnea (OR: 4.3, 95% CI: 1.2 to 16.6, p=0.03) (NYHA class III and IV vs. NYHA class I and II) determine the likelihood of pulmonary embolism after COVID-19 infection.

CONCLUSIONS: Pulmonary embolism is common in patients with new or ongoing shortness of breath after a COVID-19 infection. Pulmonary embolism is more likely to develop in patients with higher NYHA classes.
