Objective: Since the outbreak of the COVID-19 pandemic, healthcare professionals reported declining numbers of patients admitted with ST-segment myocardial infarction (STEMI) associated with increased in-hospital morbidity and mortality. However, the effect of lockdown on outcomes of STEMI patients admitted during the COVID-19 crisis has not been prospectively evaluated.Methods: A prospective, observational study on STEMI patients admitted to our tertiary care center during the COVID-19 pandemic was conducted. Outcomes of patients admitted during lockdown were compared to those patients admitted before and after pandemic-related lockdown.Results: A total of 147 patients were enrolled in our study, including 57 patients in the pre-lockdown group (November 1, 2019 to March 20, 2020), 16 patients in the lockdown group (March 21 to April 19, 2020), and 74 patients in the post-lockdown group (April 20 to September 30, 2020). Patients admitted during lockdown had significantly longer time to first medical contact, longer door-to-needle-time, higher serum troponin T levels, worse left ventricular end-diastolic pressure, and higher need for circulatory support. After a median follow-up of 142 days, survival was significantly worse in STEMI patients of the lockdown group (log-rank: p = 0.0035).Conclusions: This is the first prospective study on outcomes of STEMI patients admitted during public lockdown amid the COVID-19 pandemic. Our results suggest that lockdown might deteriorate outcomes of STEMI patients. Public health strategies to constrain spread of COVID-19, such as lockdown, have to be accompanied by distinct public instructions to ensure timely medical care in acute diseases such as STEMI.

Abstract Background The aim of the current study is to assess the natural history and prognostic value of elevated left ventricular end-diastolic pressure (LVEDP) in patients with ST-segment elevation myocardial infarction (STEMI) after reperfusion with thrombolysis; we utilize data from the Thrombolysis in Myocardial Infarction (TIMI) II study. Methods A total of 3339 patients were randomized to either an invasive (n = 1681) or a conservative (n = 1658) strategy in the TIMI II study following thrombolysis. To make the current cohort as relevant as possible to modern pharmaco-invasively managed cohorts, patients in the invasive arm with TIMI flow grade ≥ 2 (N = 1201) at initial catheterization are included in the analysis. Of these, 259 patients had a second catheterization prior to hospital discharge, and these were used to define the natural history of LVEDP in reperfused STEMI. Results The median LVEDP for the whole cohort was 18 mmHg (IQR: 12–23). Patients were divided into quartiles by LVEDP measured during the first cardiac catheterization. During a median follow up of 3 (IQR: 2.1–3.2) years, quartile 4 (highest LVEDP) had the highest incidence of mortality and heart failure admissions. In the cohort with paired catheterization data, the LVEDP dropped slightly from 18 mmHg (1QR: 12–22) to 15 mmHg (IQR: 10–20) (p = 0.01) from the first to the pre-hospital discharge catheterization. Conclusions LVEDP remains largely stable during hospitalisation post-STEMI. Elevated LVEDP is a predictor of death and heart failure hospitalization in STEMI patients undergoing successful thrombolysis. Graphic abstract

Backgrounds: Mortality and morbidity in acute myocardial infarction depend on the extent of the infarct area. Rapid recovery of coronary artery blood flow with primary percutaneous coronary intervention (pPCI) can limit the extent of infarction and improve left ventricular function. Acute myocardial infarction reduce diastolic function, which in the early stage of diastolic dysfunction, there is an increase in left ventricular end-diastolic pressure (LVEDP). The non-invasive marker of E/e’ ratio is an accurate parameter of increased LVEDP.Methods: This was a cross-sectional study enrolled consecutive patients with ST Segment Elevation Myocardial Infarction (STEMI) who underwent pPCI at Dr. Sardjito Hospital. The wire crossing time was calculated from the onset of chest pain until the guidewire crossed the infarct-related artery during the pPCI procedure. The E/e’ ratio was determined by transthoracic echocardiography which performed within 48 hours after the primary PCI. Correlation between the wire crossing time and the E/e’ ratio was assessed by the Pearson correlation test. The value of p <0.05 was considered statistically significant.Results: A total of 40 patients were enrolled in this study. The mean wire crossing time was 12.73±5.22 hours. The median value of the E/e’ ratio was 8.36 (range: 4.71-22.00). There was a moderate strength and significant correlation between the wire crossing time and the E/e’ ratio (r = 0.572; p <0.001). Patients with E/e’ ratio >15 had significantly longer wire crossing time than in patient with E/e’ ratio ≤15 (20.21±2.5 hours vs. 11.41±4.39 hours; p <0.001; respectively). The wire crossing time was independently associated the E/e’ ratio (r = 0.463; p = 0.003).Conclusion: There was a moderate strength and significant positive correlation between the wire crossing time and increased LVEDP, an earlier marker of diastolic dysfunction, measured by E/e’ ratio using TTE in patients with STEMI underwent pPCI.
