ST elevation on electrocardiogram was the most effective feature for determining myocardial infarction with a positive likelihood ratio of 13.1, whereas clinical features in isolation were not useful.
Systematic Review
Effect estimate: LR+ 13.1
Objectives: The objectives were to ascertain the value of a range of methods—including clinical features, resting and exercise electrocardiography, and rapid access chest pain clinics (RACPCs)—used in the diagnosis and early management of acute coronary syndrome (ACS), suspected acute myocardial infarction (MI), and exertional angina.
Mant et al. (Sat,) conducted a systematic review in Acute and chronic chest pain, suspected acute coronary syndrome (ACS), acute myocardial infarction (MI), and exertional angina. Clinical features, resting and exercise electrocardiography (ECG), and rapid access chest pain clinics (RACPCs) was evaluated on Determination of myocardial infarction using ST elevation on ECG (LR+ 13.1). ST elevation on electrocardiogram was the most effective feature for determining myocardial infarction with a positive likelihood ratio of 13.1, whereas clinical features in isolation were not useful.
