Impact of diabetes on epicardial reperfusion and mortality in a contemporary STEMI population undergoing mechanical reperfusion: Insights from the ISACS STEMI COVID 19 registry.
Nutr Metab Cardiovasc Dis
October 2024
Background And Aim: Diabetes has been shown in last decades to be associated with a significantly higher mortality among patients with ST-segment elevation myocardial infarction (STEMI) treated with primary PCI (PPCI). Therefore, the aim of current study was to evaluate the impact of diabetes on times delays, reperfusion and mortality in a contemporary STEMI population undergoing PPCI, including treatment during the COVID pandemic.
Methods And Results: The ISACS-STEMI COVID-19 is a large-scale retrospective multicenter registry involving PPCI centers from Europe, Latin America, South-East Asia and North-Africa, including patients treated from 1st of March until June 30, 2019 and 2020.
Background: Hypertension is the most prevalent cardiovascular risk factor, with several detrimental effects on the cardiovascular system. Contrasting results have been reported so far on its prognostic role in patients admitted for ST-segment elevation myocardial infarction (STEMI). Therefore, we investigated the impact of hypertension on short-term mortality in a large multicenter contemporary registry of STEMI patients, including patients treated during COVID-19 pandemic.

- * A study involving over 16,600 STEMI patients found a 16% reduction in PPCI procedures in 2020 compared to 2019, with the elderly experiencing the most significant delays.
- * Consequently, there was a notable increase in 30-day mortality rates during the pandemic, particularly among older patients, attributed to longer ischemia times and treatment delays.
Article Synopsis
- The COVID-19 pandemic significantly reduced the number of primary percutaneous coronary interventions (PPCIs) for ST-segment elevation myocardial infarction (STEMI) patients by 16% in 2020 compared to 2019.
- Despite this reduction affecting both genders equally, 30-day mortality rates increased notably for female patients during the pandemic, while male patients did not show a significant change.
- The analysis highlights the importance of addressing gender-specific outcomes in cardiac care during public health crises.
Article Synopsis
- The "smoking paradox" refers to lower mortality rates in smokers among STEMI patients, particularly in the context of modern primary PCI protocols during the COVID-19 pandemic.
- A large retrospective study revealed that among 16,083 STEMI patients, active smokers had better postprocedural blood flow and lower mortality rates compared to both non-smokers and previous smokers.
- The findings suggest that despite initial challenges in treatment, active smoking was linked to improved heart health outcomes in this patient population, indicating the need for further investigation into this unexpected relationship.
Article Synopsis
- - The study examined how SARS-CoV-2 positivity affects outcomes for patients with ST-segment elevation myocardial infarction (STEMI) who undergo primary percutaneous coronary intervention (PCI), using data from the ISACS-STEMI COVID-19 registry.
- - Results showed that SARS-CoV-2 positive patients were older, more likely to experience cardiogenic shock, and had worse post-procedural outcomes, including lower blood flow and increased need for thrombectomy.
- - Importantly, SARS-CoV-2 positivity was linked to higher in-hospital mortality (25.7% vs 7%) and significantly increased 30-day mortality rates (34.4% vs 8.5%), indicating that the virus
Background: Chronic obstructive pulmonary disease (COPD) is projected to become the third cause of mortality worldwide. COPD shares several pathophysiological mechanisms with cardiovascular disease, especially atherosclerosis. However, no definite answers are available on the prognostic role of COPD in the setting of ST elevation myocardial infarction (STEMI), especially during COVID-19 pandemic, among patients undergoing primary angioplasty, that is therefore the aim of the current study.

Diabetes mellitus have been recognized favoring the coronavirus infection with consequent increase mortality in COVID-19. No data have been so far reported in diabetic patients suffering from ST-elevation myocardial infarction (STEMI), a very high-risk population deserving of RASI treatment.

However, like all procedures, transradial approach is not free from complications. In this case, we describe a unique case of a large symptomatic radial artery pseudoaneurysm requiring urgent surgical intervention.
