There is limited information regarding clinical characteristics and outcomes of patients with SARS-CoV-2 (COVID-19) disease presenting with ST-segment elevation myocardial infarction (STEMI). In this multicenter retrospective study, we reviewed charts of patients admitted with symptomatic COVID-19 infection and STEMI to a total of 4 hospitals spanning Italy, Lithuania, Spain and Iraq from February 1, 2020 to April 15, 2020. A total of 78 patients were included in this study, 49 (63%) of whom were men, with a median age of 65 [58, 71] years, and high comorbidity burden. During hospitalization, 8 (10%) developed acute respiratory distress syndrome, and 14 (18%) required mechanical ventilation. 19 (24%) patients were treated with primary Percutaneous Coronary Intervention (PCI) and 59 (76%) were treated with fibrinolytic therapy. 13 (17%) patients required cardiac resuscitation, and 9 (11%) died. For the 19 patients treated with primary PCI, 8 (42%) required intubation and 8 (42%) required cardiac resuscitation; stent thrombosis occurred in 4 patients (21%). A total of 5 patients (26%) died during hospitalization. 50 (85%) of the 59 patients initially treated with fibrinolytic therapy had successful fibrinolysis. The median time to reperfusion was 27 minutes [20, 34]. Hemorrhagic stroke occurred in 5 patients (9%). Six patients (10%) required invasive mechanical ventilation; 5 (9%) required cardiac resuscitation, and 4 (7%) died. In conclusion, this is the largest case series to-date of COVID-19 positive patients presenting with STEMI and spans 4 countries. We found a high rate of stent thrombosis, indicating a possible need to adapt STEMI management for COVID-19 patients.
Background:The coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus, has had a major impact on the behavior of patients, as well as on the delivery of healthcare services. With older and more medically vulnerable people tending to stay at home to avoid contracting the virus, it is unclear how the behavior of people with acute myocardial infarction (AMI) has changed. The aim of this study was to determine if delays in presentation and healthcare service delivery for AMI exist during the COVID-19 pandemic compared to the same period a year prior. Methods:In this single-center, retrospective study, we evaluated patients admitted with ST-segment elevation myocardial infarction (STEMI) or non-ST-segment elevation myocardial infarction (NSTEMI) during early months of the COVID-19 pandemic (March 11, 2020 to April 20, 2020 compared to patients admitted with same diagnosis during the same period a year prior.Results: There were 30 and 62 patients who presented with NSTE-MI in the pandemic and pre-pandemic eras, respectively. The median pain-to-door time was significantly larger during the pandemic compared to pre-pandemic era (1,885 (880, 5,732) vs. 606 (388, 944) min, P < 0.0001). There was a significant delay in door-toreperfusion time during the pandemic with a median time of 332 (182, 581) vs. 194 (92, 329) min (P = 0.0371). There were 24 (80%) and 25 (42%) patients who presented after 12 h of pain onset in pandemic and pre-pandemic eras, respectively (P = 0.0006). There were 47 and 60 patients who presented with STEMI during the pandemic timeframe of study and pre-pandemic timeframe, respectively. The median pain-to-door time during the pandemic was significantly larger than that of the pre-pandemic (620 (255, 1,500) vs. 349 (146, 659) min, P = 0.0141). There were 22 (47%) and 14 (24%) patients who presented after 12 h of pain onset in the pandemic and prepandemic eras, respectively (P = 0.0127). There was not a significant delay in door-to-reperfusion time (P = 0.9833). There were no differences in in-hospital death, stroke, or length of hospitalization between early and late presenters, as well as between pandemic and pre-pandemic eras. Conclusions:In conclusion, this study found that patients waited significantly longer during the pandemic to seek medical treatment for AMI compared to before the pandemic, and that pandemic-specific protocols may delay revascularization for NSTEMI patients. These findings resulted in more than a threefold increase from the onset of symptoms to revascularization increasing the risks for future complications such as left ventricular dysfunction and cardiovascular death. Efforts should be made to increase patients' awareness regarding consequences of delayed presentation, and to find a balance between hospital evaluation strategies and goals of minimizing total ischemic time.
BackgroundMutation in SCARB1 gene, exon 8 rs5888, has been associated with altered lipid levels and cardiovascular risk in humans though the results have been inconsistent. We analysed the impact of SCARB1 single nucleotide polymorphism (SNP) rs5888 with plasma lipid profile and association with coronary artery disease (CAD) in a Lithuanian population characterized by high morbidity and mortality from CAD and high prevalence of hypercholesterolemia.MethodsThe study included 1976 subjects from a random sample (reference group) and an myocardial infarction (MI) group of 463 patients. Genotyping of SCARB1 (rs5888) was carried out using the real-time polymerase chain reaction method.Results/principal findingsAnalysis of rs5888 C/T gene polymorphism in the reference group revealed that male TT genotype carriers (25–74 years) had significantly higher total cholesterol and triglyceride concentrations (5.70 mmol/l vs. 5.49 mmol/l; p = 0.036, and 1.70 mmol/l vs. 1.40 mmol/l, p = 0.023, respectively) than CT carriers and the oldest males (65–74 years) TT carriers had significantly higher high density lipoprotein cholesterol concentrations in comparison to heterozygous (1.52 mmol/l vs. 1.36 mmol/l, p = 0.033). The youngest female (25–44 years) TT genotype carriers had significantly lower low density lipoprotein cholesterol concentrations in comparison to C homozygous (2.59 mmol/l vs. 2.92 mmol/l, p = 0.023). The frequency of the SCARB1 TT genotype in the oldest male MI group (65–74 years) was significantly lower than in the corresponding reference group subjects (9.4% vs. 22.3%, p = 0.006). SCARB1 TT genotype was associated with decreased odds of MI in males aged 65–75 years (OR = 0.24, 95% CI 0.10-0.56, p = 0.001).Conclusions/significanceSCARB1 polymorphism is associated with lipid metabolism and CAD in an age- and gender- dependent manner. Analysis of SCARB1 SNP rs5888 C/T genotypes revealed an atheroprotective phenotype of lipid profile in older men and in young women TT genotype carriers in the reference group. SCARB1 TT genotype was associated with decreased odds of MI in aged men.
