SummaryOur previous prospective study of post-infarction patients described a strong and significant association of increased plasma D-dimer concentrations in those who experienced a subsequent coronary death or non-fatal myocardial infarction. In the present study, we compare results on stored plasma obtained two months after the index myocardial infarction from 1,038 patients of this trial, using a simple automated latex agglutination (LA) assay in parallel with the standard ELISA test. Results show a somewhat higher mean value for the LA assay (702 ± 1092 vs. 638 ± 986 ng/ml, p = 0.0002), a strong linear correlation of the two assays (r = 0.86) and 88% agreement for values below 500 ng/ml by the ELISA test. D-dimer concentrations determined by each assay were highly correlated in patients with subsequent coronary artery events (p = 0.93) and quartile values for both the LA and ELISA were equally predictive of such events (p = 0.003 and p = 0.001, respectively). This is the first demonstration that a latex agglutination assay for D-dimer can be used to assess the prognostic risk of recurrent coronary thrombotic disease after myocardial infarction

Abstract Background While it is understood that coronavirus disease 2019 (COVID-19) is primarily complicated by respiratory failure, more data are emerging on the cardiovascular complications of this disease. A subset of COVID-19 patients present with ST-elevations on electrocardiogram (ECG) yet normal coronary angiography, a presentation that can fit criteria for myocardial infarction with no obstructive coronary atherosclerosis (MINOCA). There is little known about non-coronary myocardial injury observed in patients with COVID-19, and we present a case that should encourage further conversation and study of this clinical challenge. Case summary An 86-year-old man presented to our institution with acute hypoxic respiratory failure and an ECG showing anteroseptal ST-segment elevation concerning for myocardial infarction. Mechanic ventilation was initiated prior to presentation, and emergent transthoracic echocardiography reported an ejection fraction of 50–55%, with no significant regional wall motion abnormalities. Next, emergent coronary angiography was performed, and no significant coronary artery disease was detected. The patient tested positive for COVID-19. Despite supportive management in the intensive care unit, the patient passed away. Discussion We present a case of COVID-19 that is likely associated with MINOCA. It is crucial to understand that in COVID-19 patients with signs of myocardial infarction, not all myocardial injury is due to obstructive coronary artery disease. In the case of COVID-19 pathophysiology, it is important to consider the cardiovascular effects of hypoxic respiratory failure, potential myocarditis, and significant systemic inflammation. Continued surveillance and research on the cardiovascular complications of COVID-19 is essential to further elucidate management and prognosis.
