Abstract
Seventy percent people are able to recognize chest pain as myocardial infarction (MI) symptoms. There is no difference in awareness of MI symptoms between male and female. There is wide variation in awareness of MI symptoms. The prevalence varies from less than 5% in African countries such as Kenya, Tanzania and in Asian countries such as Nepal to as high as 90% in Germany.
Background and Objectives
Knowledge about myocardial Infarction (MI) symptoms is crucial because inadequate awareness ensures direct association with patient delay and adverse health events subsequently.
Methods
PRISMA guidelines were followed while conducting the systematic review with PROSPERO number CRD42020219802. An electronic search was conducted comprehensively through 5 databases to find those relevant articles systematically. Prevalence was calculated for each typical symptom of MI separately and subgroup analysis according to continent, country, gender and ethnicity was done. Meta-Analysis was conducted by using statistical software R version 3.4.3. A random-effects model was used.
Results
Studies from 35 different countries with 120,988,548 individuals were included in the final analysis. The prevalence of chest pain awareness was highest, while it was lowest for jaw, back, and neck pain. There was no difference in terms of awareness in males and females. Prevalence of awareness of typical MI symptoms was higher in the Caucasian white, white, and non-Hispanic white groups than in other groups. The prevalence varies from less than 5% in African countries such as Kenya, Tanzania and Asian countries such as Nepal to as high as 90% in Germany.
Conclusions
People are well aware of chest pain as a symptom of MI. However, there is limited knowledge regarding other typical symptoms of MI.
