Background: Acute myocardial infarction is one of the most common causes of mortality in developed countries, and high-sensitive troponin test usually becomes positive within 3 h from the onset of symptoms. Myocardial perfusion index (Tei index) is a parameter measured during the echocardiographic examination. Objectives: The aim of this study is to investigate the diagnostic value of the Tei index for early diagnosis of acute myocardial infarction in the emergency department and to evaluate the correlation between the Tei index and Hs-Troponin value. Materials and Methods: A total of 129 cases were evaluated, and patients were divided into two groups according to their final diagnosis as “acute myocardial infarction (non-ST segment elevation myocardial infarction)” and “non-acute myocardial infarction” groups. Baseline and third-hour Hs-Troponin levels and Tei index values were determined, and their correlation was analyzed. Results: A total of 84 cases were diagnosed with acute myocardial infarction (non-ST segment elevation myocardial infarction), 84.5% had positive Tei index results at the time of admission while the remaining 45 patients were diagnosed as non-acute myocardial infarction and only 48.9% of them had positive Tei index. The diagnostic value of the Tei index and Hs-troponin were calculated as 79.8% and 60%; 67.9% and 60%, respectively. Also, we found that a 0.02 or more increase in the Tei index value has a 97.6 sensitivity and 97.5 specificity for the diagnosis of non-ST segment elevation myocardial infarction. A weak correlation was found between the Tei index and Hs-Troponin values in the acute myocardial infarction group (r = 0.425) and a negative correlation in non-acute myocardial infarction patients at presentation. Conclusion: It is suggested that the use of Tei index might be used as a supportive measure for the early diagnosis of acute myocardial infarction, and the deterioration of Tei index seems to be more significant than Hs-Troponin especially in ruling out acute myocardial infarction.

Venous Stents

Venous thromboembolism is associated with significant morbidity and mortality if left untreated. Anticoagulation is the cornerstone of treatment. Venous stents are a relatively newer entity that are increasingly being used to treat venous stenosis/occlusion. It is a safe procedure, but complications include vein rupture, arterial puncture, retroperitoneal bleeding, and in-stent thrombosis. Stent migration is a rare but potentially fatal complication. We present a case of venous stent embolization to the heart that presented as a non-ST segment elevation myocardial infarction.

Background: Stay at home orders and fear of acquiring COVID-19 may have led to an avoidance of care for medical emergencies including acute myocardial infarction (AMI). We sought to examine rates of confirmed AMI cases between January 1-June 30, 2019 and 2020. Methods: We identified Kaiser Permanente Southern California members ≥ 18 years old with a hospitalization or emergency department visit for AMI, defined by ICD-10 primary diagnosis codes. Rates of AMI per 100,000 member-weeks were calculated for pre-pandemic and pandemic periods of January 1-March 3, 2020 and March 20-June 30, 2020, respectively, and in the same periods of 2019 overall and for ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI), separately. March 4-19, 2020 was considered a washout period given the gradual rollout of stay-at-home orders. Rate ratios (RR) and 95% confidence intervals (CI) were calculated comparing pre-pandemic and pandemic periods of 2020 to 2019 using Poisson regression. Results: The mean age of patients presenting with AMI during the 2020 (n=3,029) and 2019 (n=3,518) periods was 69 years, and a majority of events occurred among men (62%) and whites (47%). Rates of AMI in the pre-pandemic period of 2020 and same period in 2019 were 4.23 and 4.45 per 100,000 member weeks, respectively. During the pandemic period of 2020 and the same period in 2019, rates were 3.04 and 3.85 per 100,000 member-weeks, respectively. (Figure) There was no evidence rates of AMI were different during the pre-pandemic period of 2020 compared to the same period in 2019 (RR 0.95, 95% CI 0.88, 1.03). In contrast, rates of AMI were lower during the pandemic period of 2020 compared to the same period of 2019 (RR 0.79, 95% CI 0.74, 0.85), and among NSTEMI (RR 0.80, 95% CI 0.74, 0.86) and STEMI (0.74, 95% CI 0.66, 0.84) cases. Conclusion: AMI rates were lower during the COVID-19 pandemic compared to the year prior. Public health messaging is important to ensure people seek care for medical emergencies.
