Very Early Discharge After Primary Percutaneous Coronary Intervention for ST-Elevation Myocardial Infarction: Mortality Outcomes at Six Months

Safety of an Early Discharge Strategy (≤48 h) after ST-Elevation Myocardial Infarction

Background: Early discharge following ST-segment-elevation myocardial infarction (STEMI) confers notable advantages for both patients and healthcare systems. However, the adoption of a very early discharge strategy for selected patients remains limited due to safety considerations. We aimed to provide some insight into the safety of a discharge program with a hospital stay lasting <48 h after a primary percutaneous coronary intervention (PCI). Methods: Using a registry of 1105 patients undergoing primary PCI for STEMI in our hospital between January 2015 and October 2023, we enrolled all the patients who had a hospital stay ≤48 h, according to a prespecified institutional protocol. The primary objective was a combined rate of non-fatal stroke, non-fatal acute myocardial infarction, or cardiovascular death within 30 days of discharge. Emergency department visits or hospitalizations due to cardiovascular causes, along with the all-cause mortality, were measured during the same period. Results: A total of 453 (41%) patients were discharged ≤48 h after admission for a STEMI. The mean age was 62.4 (±12.5 years), 24.3% were women, and 17.9% were people with diabetes. Up to 96% of the procedures had been performed through radial artery access, and there were no major vascular complications. Regarding the primary endpoint, there was one event (0.2%; one patient suffered a non-fatal myocardial infarction). There were no cardiovascular deaths or deaths from other causes. Only five patients (1.1%) were re-hospitalized or visited the emergency department due to cardiovascular causes. Conclusions: An early discharge strategy for patients within 48 h of experiencing STEMI and undergoing primary PCI appears feasible and safe.

Impact of the COVID-19 Outbreak on the Treatment of Myocardial Infarction Patients

Purpose of review

The COVID-19 pandemic has led to an overburdened healthcare system. While an increased rate of ACS is expected due to the pro-thrombotic state of COVID patients, observed ACS incidence and admission rates were paradoxically decreased during the (first wave of the) pandemic. In this narrative review, we will discuss potential reasons for this decrease in ACS incidence. Furthermore, we will discuss ACS management during the COVID-19 pandemic, and we will discuss outcomes in ACS.

Recent findings

A reluctance to seek medical contact (in order not to further overburden the health system or due to fear of being infected with COVID-19 while in hospital) and unavailability of medical services seem to be important factors. This may have led to an increased symptom onset to first medical contact time and an increased rate of out-of-hospital cardiac arrests. A trend towards less invasive management was observed (less invasive coronary angiography in NSTEMI patients and more "fibrinolysis-first" in STEMI patients), although a large variation was observed with some centers having a relative increase in early invasive management. Patients with ACS and concomitant COVID-19 infection have worse outcomes compared to ACS patients without COVID-19 infection. All of the above led to worse clinical outcomes in patients presenting with ACS during the COVID-19 pandemic. Interestingly, staffing and hospital bed shortages led to experimentation with very early discharge (24 h after primary PCI) in low-risk STEMI patients which had a very good prognosis and resulted in significant shorter hospital duration.

Summary

During the COVID-19 pandemic, ACS incidence and admission rates were decreased, symptom onset to first medical contact time prolonged, and out-of-hospital rates increased. A trend towards less invasive management was observed. Patients presenting with ACS during the COVID-19 pandemic had a worse outcome. On the other hand, experimental very early discharge in low-risk patients may relieve the healthcare system. Such initiatives, and strategies to lower the reluctance of patients with ACS symptoms to seek medical help, are vital to improve prognosis in ACS patients in future pandemics.
