Insights
Electrocardiogram (ECG) abnormalities were found in nearly one in five Ugandans at risk for Long COVID. This highlights the need for integrated ECG screening in Long COVID follow-up care.
Area of Science:
- Cardiology
- Infectious Diseases
- Public Health
Background:
- COVID-19 is known to cause significant cardiovascular complications.
- Long COVID can manifest with various persistent symptoms, including cardiovascular effects.
- Understanding these long-term cardiovascular impacts is crucial for patient management.
Purpose of the Study:
- To investigate the prevalence of electrocardiographic (ECG) abnormalities in individuals at risk of developing Long COVID in Uganda.
- To identify potential risk factors associated with these ECG abnormalities.
- To inform clinical practice regarding cardiovascular monitoring post-COVID-19.
Main Methods:
- A cross-sectional study was conducted between February and June 2022.
- Standard resting ECGs were performed on 244 participants at least 2 months post-acute COVID-19.
- Data on sociodemographics, clinical characteristics, and vital signs were collected.
Main Results:
- 18.9% of participants exhibited abnormal ECG findings.
- Non-specific T-wave inversion was the most common abnormality.
- Females had a lower prevalence of ECG abnormalities (aPR: 0.52), while smokers had a higher prevalence (aPR: 2.03).
Conclusions:
- A significant proportion of individuals at risk for Long COVID in Uganda presented with ECG abnormalities.
- ECG screening should be considered for integration into the follow-up care of patients at risk of Long COVID.
- These findings underscore the importance of cardiovascular surveillance in post-COVID-19 care.
Background:
COVID-19 has a significant cardiovascular involvement. Electrocardiographic (ECG) abnormalities among people at a risk of Long COVID in Uganda was investigated.
Methods:
A cross-sectional study was conducted from February to June 2022 at the post COVID - 19 clinic in Mulago National Specialized Hospital, Kampala. A standard resting ECG was performed on individuals at least 2 months following acute COVID-19, with a negative SARS-CoV-2 reverse-transcription polymerase chain reaction. Sociodemographic and clinical characteristics as well as vital signs were recorded for all study participants.
Results:
Of the 244 study participants, 117 (47.9%) were female. The median age of all the participants was 33.0 (interquartile range: 26.0 - 43.5) years. Twenty-five (10.2%) participants had a history of smoking while 117 (48%) had a history of alcohol intake. In total, 46 (18.9%) had abnormal ECG findings (95% Confidence Interval (CI): 14.39 - 24.29) and non-specific T-wave inversion (n = 16, 34%) was the most frequent ECG abnormality. The proportion of participants with ECG abnormalities was 48% lower among females (adjusted prevalence ratio (aPR): 0.52, 95% CI: 0.28 - 0.96, p value < 0.05) and 2-fold greater for those with a history of smoking (aPR: 2.03, 95% CI:1.096 - 3.776, p value < 0.05).
Conclusion:
One in five Ugandans who were checked at the clinic at a risk of Long COVID showed ECG abnormalities. ECG screening is suggested to be integrated into the follow-up care of those at a risk of Long COVID.
