Abstract

A paradigm shift demonstrating the feasibility of using the radial artery for primary angioplasty and the evaluation of high-risk subgroups. Materials and methods: The nature of the research may be described as prospective, observational, and descriptive. Patients who presented with acute ST-segment elevation myocardial infarction (STEMI) and were treated with PCI via RA at the cardiology department of a tertiary care centre were included in the study. The interventionist was given complete autonomy in deciding whether to use a RA or FA strategy. Patients who had PCI performed through the femoral artery were not allowed to participate in this research. Patients were hospitalized and underwent evaluation for baseline features such clinical history, physical examination, and investigations such as electrocardiogram, two-dimensional echo, and normal laboratory investigation. After that, patients were separated into two groups for the subgroup analysis: HRG patients and non-HRG patients. Patients with unfavourable characteristics were included in the HRG. These characteristics included age (greater than 80 years), cardiogenic shock, severe left ventricular systolic dysfunction, high degree AV block, low body surface area (BSA), multi-vessel percutaneous coronary intervention (PCI), diabetes mellitus, and low body mass index (BMI). Patients who did not have these characteristics were included in the non-HRG.
