ABSTRACT

Silent myocardial infarction or unrecognized myocardial infarction has increased prevalence in elderly population with increased cardiovascular risk factors. However, its prevalence in COVID-19 patients is not well-known. A 77-year-old Caucasian male with COVID-19 pneumonia, presented with silent ST-segment elevation myocardial infarction, diabetic ketoacidosis and multiorgan failure. He underwent cardiac catheterization and drug eluting stent placement in the ostial right coronary artery with safety protocol. He was discharged to extended-care-facility in stable condition. This is a first case report of silent ST-segment elevation myocardial infarction in a patient presenting with COVID-19. In patients with COVID-19, acute myocardial infarction should be ruled out even when asymptomatic, especially in older patients. Prompt intervention using safety protocol is life-saving.

ABSTRACT

Coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2 has varied manifestation with multisystem involvement. Acute coronary syndrome in COVID-19 as a result of stent thrombosis is an uncommon entity and is often due to hypercoagulable state. A 40-year-old male was referred to us with acute onset chest pain. He also reported fever, sore throat and dry cough for six days which mandated testing for COVID-19 which turned out to be positive. He had a prior history of coronary artery disease with a drug eluting stent implanted two years back. An electrocardiogram was suggestive of acute anterior wall myocardial infarction while echocardiogram revealed hypokinesia of left anterior descending (LAD) artery territory. Coronary angiogram revealed non-occlusive thrombus in proximal LAD stent. A Thrombolysis in Myocardial Infarction (TIMI) III flow was restored following balloon angioplasty with a non-compliant balloon and use of glycoprotein (GP) IIb-IIIa receptor antagonist. A diagnosis of very late stent thrombosis subsequent to COVID-19 was made.

ABSTRACT

COVID-19 has varied cardiovascular manifestations including microvascular and macrovascular thrombi leading to multiorgan system injury and failure. This case describes a patient presenting with acute hypoxaemic respiratory failure from COVID-19 who abruptly developed a large thrombus in the right coronary artery leading to myocardial infarction. This case report reviews the ECG, heart catheterisation images prepercutaneous and postpercutaneous coronary intervention, critical care management and outcome in the context of the height of the COVID-19 pandemic in the Virginia area. A brief review of relevant literature regarding cardiovascular complications of COVID-19 is also provided. Unfortunately, the patient ultimately passed after 2 weeks of inability to wean off the ventilator.

ABSTRACT

OBJECTIVES: We sought to investigate stent healing and neointimal hyperplasia with ihtDEStiny drug-eluting stent (DES) by optical coherence tomography (OCT) examination conducted 9 months after implantation. BACKGROUND: The currently used DES present certain features that have been linked separately to their better performance in terms of efficacy and safety. METHODS: First-in-man, prospective and multicenter study including patients treated with ihtDEStiny stent undergoing OCT examination at 9 months follow up. The ihtDEStiny stent is a sirolimus eluting stent with an oval shape ultrathin struts (68 µm) and an abluminal coating of a fluoropolymer containing the antiplatelet agent triflusal. Primary endpoint was the percentage of obstruction of the in-stent volume by the neointima. RESULTS: In 58 patients (63 lesions) in-stent late lumen loss was 0.11 ± 0.23 mm (95% CI 0.05-0.16) with only in 6% of stents being > 0.5 mm and in-segment binary stenosis was 1.6%. In OCT mean neointima volume obstruction was 10.5 ± 6.9% with a mean neointima thickness of 110.9 ± 89.8 µm. The proportion of uncovered struts was 2.5%, malapposed struts 1.1% and malapposed/uncovered struts 0.7% and no subclinical thrombi detected. Mean incomplete stent apposition area was 0.1 ± 0.1 mm2. At 12 months target lesion revascularization rate was 3% and no stent thrombosis was reported. CONCLUSIONS: In this study the ihtDEStiny stent has shown a very low degree of neointimal proliferation associated with a low rate of uncovered/malapposed struts and total absence of subclinical thrombi at 9 months follow up.

ABSTRACT

BACKGROUND: Patients with diabetes have more extensive coronary disease, resulting in higher risks of adverse clinical events following stenting. In all-comer patients, contemporary DES have shown excellent safety and efficacy, but data on diabetic patients are scarce. Separately for the BIO-RESORT and BIONYX trials, we assessed the 2-year clinical outcomes of diabetic patients, treated with various contemporary drug-eluting stents (DES). METHODS: We performed two prespecified secondary analyses of two randomized DES trials, which both stratified for diabetes. The main endpoint was target vessel failure (TVF), a composite of cardiac death, target vessel myocardial infarction, or target vessel revascularization. Follow-up was finished before the COVID-19 pandemic. RESULTS: In BIO-RESORT, 624/3514 (17.8%) had diabetes: 211 received Orsiro sirolimus-eluting stents (SES), 203 Synergy everolimus-eluting stents (EES), and 210 Resolute Integrity zotarolimus-eluting stents (RI-ZES). TVF did not differ between SES (10.2%) and EES (10.0%) versus RI-ZES (12.7%) (SES vs. RI-ZES HR:0.78, 95%-CI [0.44-1.40]; p = 0.40, EES vs. RI-ZES HR:0.79, 95%-CI [0.44-1.40]; p = 0.42). In BIONYX, 510/2488 (20.5%) patients had diabetes: 250 received SES and 260 Resolute Onyx zotarolimus-eluting stents (RO-ZES). There was no difference in TVF between SES (10.7%) versus RO-ZES (12.2%) (HR:0.88, 95%-CI [0.52-1.48]; p = 0.63). CONCLUSIONS: There was no difference in 2-year clinical outcome among patients with diabetes, who were treated with SES, or EES, versus RI-ZES. In addition there was no difference in clinical outcome in diabetic patients, who were treated with SES versus RO-ZES. These findings may be considered as a signal of safety and efficacy of the studied DES in patients with diabetes.
