Abstract: Abstract: Background: Prompt diagnosis of acute myovardial infarction or acute coronary syndrome is very important. Aim: A systematic review was conducted to determinate the accuracy of 10 important signs and symptoms in selected and non-selected patients. Design of study: Diagnostic meta-analysis. Method: Using Medline, Cinahl, Embase, tracing references, and by contacting experts, studies that described one of the ten signs and symptoms on one or both conditions were identified. Studies were excluded if they were not based on original data. Validity was assesses using Quada and all data were pooled using a random effects model. Resuls: Sixteen of the 28 included studies were about patients who were non-selected. In this group, absence of chest-wall tenderness on palpation had a pooled sensitivity of 92% (95% confidence interval [CI] = 86 to 96) for acute myocardial infarction and 94 % (95% CI = 91 tot96) for acute coronary syndrome. Oppressive pain followed with a pooled sensitivity of 60% (95% CI = 55 to 66) for acute myocardial infarction. Sweating had the highest pooled positive likelihood ratio (LR+), namely 2.92 (95% CI = 1.97 to 4.23) for acute myocardial infarction. The other pooked LR+ fluctuated between 1.05 and 1.49. Negative LRs (LR-) varied between 0.98 and 0.23. Absence of chest-wall tenderness on palpation had a LR- of 0.23 (95% CI = 0.18 to 0.29). Conclusion: Based on this meta-analysis it was not possible to define an important role for signs and symptoms in the diagnosis of acute myocardial infarction or acute coronary syndrome. Only chest -wall tenderness on palpation largely ruled out acute myocardial infarction or acute coronary syndrome in low -prevalence settings.
