Interplay between climate, pollution and COVID-19 on ST-elevation myocardial infarction in a large metropolitan region.

Background: Collective risk factors such as climate and pollution impact on the risk of acute cardiovascular events, including ST-elevation myocardial infarction (STEMI). There is limited data however on the precise temporal and independent association between these factors and STEMI, and the potentially interacting role of government policies against Coronavirus disease 2019 (COVID-19), especially for Latin America.

Methods: We retrospectively collected aggregate data on daily STEMI admissions at 10 tertiary care centers in the Buenos Aires metropolitan area, Argentina, from January 1, 2017 to November 30, 2020.

One-Year Follow-Up Results From the Observational, Multicenter, Prospective, and Controlled Registry: The WALTZ All-Comers Study.

The aim of this study was to evaluate 1-year follow-up results in an all "comers" population treated with a new cobalt chromium bare-metal stent (BMS) design. Since August 2016 to March 2017, 201 (9.7% of screening population) consecutive patients undergoing coronary stent implantation in 11 centers in Argentina were prospectively included in our registry.

Lowering risk score profile during PCI in multiple vessel disease is associated with low adverse events: The ERACI risk score.

In recent years angiographic risk scores have been introduced in clinical practice to stratify different levels of risk after percutaneous coronary interventions (PCI). The SYNTAX score included all intermediate lesions in vessels ≥1.5 mm, consequently, multiple stent implantation was required.
