A growing volume of evidence correlates SARS-CoV-2 infection with myocardial injury, exposing patients to higher mortality risk. SARS-CoV-2 attacks the coronary arterial bed with various mechanisms including thrombosis/rupture of preexisting atherosclerotic plaque, de novo coronary thrombosis, endotheliitis, microvascular dysfunction, vasculitis, vasospasm, and ectasia/aneurysm formation. The angiotensin-converting enzyme 2 receptor plays pivotal role on the cardiovascular homeostasis and the unfolding of COVID-19. The activation of immune system, mediated by proinflammatory cytokines along with the dysregulation of the coagulation system, can pose an insult on the coronary artery, which usually manifests as an acute coronary syndrome (ACS). Electrocardiogram, echocardiography, cardiac biomarkers, and coronary angiography are essential tools to set the diagnosis. Revascularization is the first-line treatment in all patients with ACS and obstructed coronary arteries, whereas in type 2 myocardial infarction treatment of hypoxia, anemia and systemic inflammation are indicated. In patients presenting with coronary vasospasm, nitrates and calcium channel blockers are preferred, while treatment of coronary ectasia/aneurysm mandates the use of antiplatelets/anticoagulants, corticosteroids, immunoglobulin, and biologic agents.

Various clinical and laboratory parameters, adverse events, and disease activity indices were assessed, alongside drug efficacy and survival rates.RESULTSPatients with D2T RA exhibited higher seronegativity, prior use of bDMARDs and cDMARDs, and longer disease duration. Both groups experienced reductions in VAS and DAS28 scores, as well as SDAI, CDAI, HAQ, CRP, and ESR levels at baseline and 3, 6, and 12 months post-baricitinib initiation, with sustained efficacy observed over 12 months. The most prevalent adverse event was infection (28.21%). Although initial drug survival rates were similar between groups, the non-D2T RA group demonstrated higher rates at 24 months (46.70% vs. 59.40%).
