Insights
Antiplatelet therapy in COVID-19 patients showed more typical radiological findings but did not impact ventilation needs or outcomes. Mechanical ventilation remained the strongest predictor of a poor outcome in these patients.
Area of Science:
- Cardiology
- Pulmonology
- Infectious Diseases
Background:
- COVID-19 presents a significant risk for both venous and arterial thromboembolism.
- The role of antiplatelet therapy in modifying the disease course of COVID-19 requires further investigation.
Purpose of the Study:
- To investigate the effect of antiplatelet therapy on the clinical course and outcomes of hospitalized COVID-19 patients.
- To identify predictors of adverse outcomes, including the need for mechanical ventilation and typical radiological findings.
Main Methods:
- A cohort of 152 hospitalized COVID-19 patients was evaluated.
- Data collected included demographics, comorbidities, medication use (antiplatelets, anticoagulants), laboratory findings, and mechanical ventilation status.
- Patient outcomes were categorized as 'good' (discharged) or 'bad' (deceased or referred to higher care).
Main Results:
- The need for mechanical ventilation was the strongest predictor of a bad outcome.
- Patients on antiplatelet medication showed a higher incidence of typical radiological findings.
- Factors predicting the need for ventilatory support included elevated LDH and CRP levels, cardiac conduction abnormalities, and chronic lung conditions.
Conclusions:
- While antiplatelet use correlated with typical radiological findings in COVID-19, it did not alter ventilation requirements or patient outcomes.
- Mechanical ventilation remains the most critical factor associated with poor prognosis in COVID-19 patients.
Introduction:
Covid-19 is associated with a high risk of venous thromboembolism. In addition, cases of arterial thromboembolism were also reported. We investigated the effect of antiplatelet therapy on the disease course.
Methods:
We evaluated a cohort of inpatients with Covid-19 (n = 152). We recorded the patient's demographic data, their comorbidities, medication use including the use of antiplatelets and anticoagulants, laboratory findings and data about mechanical ventilation. We then separated the patient's outcomes into either being "bad" (dead or referral to higher level of care) or "good" (discharged). Then we evaluated the factors that contributed to the patient needing ventilatory support and to showing typical radiological findings.
Results:
In our cohort, 21 patients received ventilatory support whereas 131 did not require the use of ventilators. 127 patients had good outcomes and 25 had bad outcomes. By using multivariate analysis, we found that the need for ventilatory support was the strongest predictor of a bad outcome. All patients who were on ventilators displayed typical radiological findings. The factors predicting the need for ventilatory support were LDH and CRP levels, the presence of cardiac conduction abnormalities as well as chronic lung conditions. Cardiac conduction abnormalities, LDH and CRP levels, and the use of antiplatelets, were factors that predicted typical radiological findings.
Conclusions:
There was a higher incidence of typical radiological findings in patients on antiplatelet medication. However, it did not translate into changes in the ventilation requirement or in the outcome. The need for mechanical ventilation was the strongest predictor of a bad outcome.
