Background. The viral load of asymptomatic SAR-COV-2 positive (ASAP) persons have been equal to that of symptomatic patients, suggesting a similar risk for endothelial dysfunction and increased coagulation in asymptomatic and symptomatic patients. To date, there are no reports of ST-elevation myocardial infarction (STEMI) outcomes in ASAP patients. We evaluated thrombus burden and thrombus viral load and their impact on microvascular bed perfusion in the infarct area (myocardial lush grade, MBG) in ASAP compared to SARS-COV-2 negative (SANE) STEMI patients. Methods. This was an observational study of 46 ASAP, and 130 SANE patients admitted with confirmed STEMI treated with primary percutaneous coronary intervention and thrombus aspiration. The primary endpoints were thrombus dimension + thrombus viral load effects on MBG after PPCI. The secondary endpoints during hospitalization were major adverse cardiovascular events (MACEs). MACEs are defined as a composite of cardiovascular death, nonfatal acute AMI, and heart failure during hospitalization.Results. Thrombus dimensions were significantly higher in ASAP patients as compared to SANE patients. Interestingly, 39 (84.9%) of ASAP patients also had thrombus specimens positive for SARS-COV-2. In ASAP STEMI patients (n=46), thrombus viral load was a significant determinant of thrombus dimension independently of risk factors (pConclusions. In ASAP patients presenting with STEMI, there is strong evidence towards higher thrombus viral load, dimension, and poorer MBG. These data support the need to reconsider ASAP status as a risk factor that may worsen STEMI outcomes. |
