Introduction: Efforts to control the COVID-19 pandemic brought sweeping social change, with stay-at-home orders and physical distancing mandates in 43 of 50 states by April 2020. Early on, isolated studies around the world described reduced hospital admissions. Reports from some US hospitals also described declines in catheterization laboratory activations, and acute myocardial infarction (AMI) and stroke admissions. However, there have been few population-based analyses of emergency department (ED) visits to verify these initial reports and describe longer term impacts of the pandemic on care seeking behavior. Hypothesis: We hypothesized that AMI and stroke ED visits in North Carolina (NC) would decrease substantially after a statewide stay-at-home order was announced on March 27, 2020. Methods: We analyzed all ED visits from January 5 to August 28, 2020 using data collected by the NC Disease Event Tracking and Epidemiologic Collection Tool, a syndromic surveillance system that automatically gathers ED data in near-real time for all EDs in NC. Counts of AMI and stroke/transient ischemic attack (TIA) were ascertained using ICD-10-CM diagnosis codes. We compared weekly 2020 ED visit data before and after NC’s stay-at-home order, and to 2019 ED visit data. Results: Overall ED volume declined by 44% in the weeks before and after the stay-at-home order ( Figure ) while the prior year’s ED volume stayed steady at ~100,000 visits per week. From January 5 to March 28, there were 593 AMI and 791 stroke/TIA visits per week on average. By April 11, ED visits reached a nadir at 426 AMI and 543 stroke/TIA visits per week, representing a 28% and 31% decrease, respectively. Since June, AMI and stroke/TIA ED visits have rebounded slightly but have yet to reach pre-pandemic levels. Conclusions: We observed swift declines in AMI and stroke/TIA ED visits following NC’s stay-at-home order. These findings potentially reflect the avoidance of medical care due to fears of COVID-19 exposure and may eventually result in higher associated case fatality.

The Creation

SummaryAnalysis of electrocardiograms tape-recorded from patients admitted to hospital with acute myocardial infarction revealed that the pattern of ventricular extrasystolic activity was not significantly different among those who subsequently developed ventricular fibrillation and those who did not. Episodes of ventricular fibrillation occurred predominantly within 4 hours from the start of infarction. Patients were 3 times less likely to survive an episode of ventricular fibrillation if they also had left ventricular failure than if this feature was absent. Management of episodes of ventricular fibrillation was compared in patients before and after the creation of a specially staffed and equipped coronary care unit. The success of electric shock as a treatment for ventricular fibrillation was similar before and after the creation of the coronary care unit. An attempt was made to determine which features in the management of ventricular fibrillation in this and in previously published series were associated with patient survival.

Abstract Background In multiple studies, the potential relationship between daylight saving time (DST) and the occurrence of acute myocardial infarction (MI) has been investigated, with mixed results. Using the Dutch Percutaneous Coronary Intervention (PCI) registry facilitated by the Netherlands Heart Registration, we investigated whether the transitions to and from DST interact with the incidence rate of PCI for acute MI. Methods We assessed changes in hospital admissions for patients with ST-elevation myocardial infarction (STEMI) or non-STEMI (NSTEMI) undergoing PCI between 1 January 2015 and 31 December 2018. We compared the incidence rate of PCI procedures during the first 3 or 7 days after the transition with that during a control period (2 weeks before transition plus second week after transition). Incidence rate ratio (IRR) was calculated using Poisson regression. Potential gender differences were also investigated. Results A total of 80,970 PCI procedures for STEMI or NSTEMI were performed. No difference in incidence rate a week after the transition to DST in spring was observed for STEMI (IRR 0.95, 95% confidence interval (CI) 0.87–1.03) or NSTEMI (IRR 1.04, 95% CI 0.96–1.12). After the transition from DST in autumn, the IRR was also comparable with the control period (STEMI: 1.03, 95% CI 0.95–1.12, and NSTEMI: 0.98, 95% CI 0.91–1.06). Observing the first 3 days after each transition yielded similar results. Gender-specific results were comparable. Conclusion Based on data from a large, nationwide registry, there was no correlation between the transition to or from DST and a change in the incidence rate of PCI for acute MI.

In acute myocardial infarction (AMI), lack of oxygen delivery to myocardium leads to generation of reactive oxygen species (ROS) which play an important role in the pathogenesis of AMI. Endogenous anti-oxidants protect the myocardial tissues from the deleterious effect of free radical mediate injury. The study evaluates the extent of oxidative stress and antioxidant status against ROS in AMI patients and amelioration of oxidative stress after regular treatment and also assesses the association between oxidative stress and risk factors for atherosclerosis like dyslipidemia and diabetes mellitus (DM).The study was conducted on 72 AMI patients and age and sex matched 18 healthy controls. Patients were assigned to four groups, AMI without dyslipidemia or DM, with dyslipidemia, with DM and with both dyslipidemia and DM. Plasma malondialdehyde (MDA) and GSH content and vitamin E levels were determined on admission into hospital and on the 5th day of treatment. Plasma MDA level increased significantly (p<0.001) and erythrocyte GSH and plasma vitamin E levels were decreased (p<0.001) in all the groups of patients as compared to control. On the 5th day of regular treatment MDA level reduced (p<0.001) and GSH and vitamin E levels increased (p<0.001) in patients. The plasma MDA level was significantly higher (p<0.001) in patients with both dyslipidemia and DM or with only DM in comparison to patients without dyslipidemia and DM. The difference in the GSH level between patients with risk factors and without risk factors was not significant. It may be conclude that an imbalance exists between oxidant and antioxidant molecules in AMI patients which shift towards oxidative side and regular treatment restores this balance. There may be some association between oxidative stress in AMI and risk factors like dyslipidemia and diabetes mellitus.Bangladesh Med Res Counc Bull 2014; 40 (2): 79-84

The Impact

Introduction: Smoking is a well established risk factor for acute myocardial infarction (AMI). The potential impact of a nationwide comprehensive smoking ban (CSB) legislation on the incidence of AMI hospital admissions is not known. The aim of this analysis is to determine the impact of a nationwide CSB legislation on the incidence of AMI hospitalizations. Methods: We contacted the department of health at states with no CSB law for information on the total number of AMI discharges (ICD-9-CM 410), length of stay and charges in dollars for 2007. Expected decrease in the number of AMI in the year following a potential implementation of a nationwide CSB was calculated by multiplying the current number of AMI by the pooled relative risk reduction (RRR) obtained from a recent published meta analysis (RR 0.89). Results: In 2007, 37 States had CSB laws. There were 169,043 AMI hospitalizations in states without CSB. A nationwide smoking ban would result in 18,596 less AMI hospitalizations in the year following such a ban. This is associated with more than 92 million dollars in direct cost savings. Conclusion: A nationwide CSB legislation would result in significant reduction in the number of AMI hospitalizations. This is associated with significant cost saving. Further studies are needed to evaluate the impact of CSB on admission from other disease states.

In acute myocardial infarction (AMI), generation of free radicals contribute to its pathogenesis. We evaluated the extent of oxidative stress and its amelioration in AMI patients after regular treatment and assessed its association with risk factors like dyslipidemia and diabetes mellitus (DM). Plasma MDA level increased (p<0.001) and erythrocyte GSH and plasma vitamin E levels decreased (p<0.001) in AMI patients. On the 5th day of regular treatment MDA level reduced (p<0.001) and erythrocyte GSH and vitamin E levels increased (p<0.001). The rise in MDA and fall in vitamin E levels were significant (p<0.001) in patients with both dyslipidemia and DM in comparison to patients without dyslipidemia or DM. It is concluded that an imbalance exists between oxidant and antioxidant molecules in AMI patients which shifts towards oxidative side and treatment restores this balance. There may be some association between oxidative stress in AMI and risk factors like dyslipidemia and diabetes mellitus.University Heart Journal Vol. 10, No. 2, July 2014; 60-65
