Insights
COVID-19 survivors show increased risk of myocardial ischemia and need for cardiac interventions. Myocardial perfusion scans (MPS) are reliable for assessing cardiovascular symptoms post-COVID-19.
Area of Science:
- Cardiology
- Infectious Diseases
- Public Health
Background:
- COVID-19 infection can impact cardiovascular health.
- Long-term effects of COVID-19 on the heart are still being investigated.
- Understanding post-COVID-19 cardiac complications is crucial for patient management.
Purpose of the Study:
- To determine if COVID-19 infection increases the risk of myocardial ischemia on myocardial perfusion scans (MPS).
- To assess if COVID-19 survivors require more coronary angiographies (CAG).
- To evaluate the necessity for invasive treatments (stent implantation, CABG) or medical therapy in COVID-19 patients.
Main Methods:
- A study group of patients with symptomatic COVID-19 (PCR positive) within 6 months underwent MPS.
- A control group of age- and gender-matched patients, who underwent MPS before the pandemic (Jan 2019-Sep 2019), was selected.
- Frequencies of ischemia, CAG, and treatments were compared between the COVID-19 group and the control group.
Main Results:
- Ischemia was significantly more frequent in the COVID-19 group (p < 0.001).
- The need for invasive evaluation (CAG) and treatment (medical or invasive) was higher in the COVID-19 group, regardless of MPS results (p=0.006 and p=0.015).
- This trend persisted for patients with abnormal MPS results but not for those with ischemia.
Conclusions:
- COVID-19 infection is associated with a significant increase in myocardial ischemia, CAG procedures, and cardiac treatments.
- Myocardial perfusion scan (MPS) is a reliable tool for evaluating cardiovascular symptoms in patients with a history of COVID-19.
Purpose:
To investigate if (i) the risk of ischemia on myocardial perfusion scan (MPS), (ii) number of coronary angiographies (CAG) performed, and (iii) necessity for invasive (stent implantation or coronary artery bypass grafting (CABG)) or medical treatment increased in patients infected with COVID-19.
Methods:
Patients who were referred to MPS between August 2020 and April 2021 with a history of active symptomatic COVID-19 infection (confirmed by PCR positivity) in the last 6 months were involved in the study group. Age-and gender-matched control group was composed of randomly chosen patients who attended for MPS between January 2019 and September 2019, before pandemic. Frequency of ischemia, CAG, and invasive or medical treatments were compared between groups.
Results:
Ischemia was reported more frequently in the study group (p < 0.001). In clinical evaluation, regardless of the MPS results, the necessity for invasive evaluation with CAG and treatment (either medical therapy or invasive interventions) was higher in the study group (p = 0.006 and p = 0.015). It was also true for patients with abnormal MPS results (p = 0.008 and p = 0.024) but not for the patients with ischemia (p = 0.29 and p = 0.06).
Conclusion:
There exists a significant increase in the frequency of ischemia on MPS, undergoing CAG, stent implantation or CABG, and initiation of medical therapy in patients with a history of COVID-19 infection in the last 6 months. MPS is a reliable method in patients who present with cardiovascular symptoms in the late COVID period.
