Cardiac arrest: a case-based review.

BACKGROUND Coffee is commonly consumed among young people in China. However, consumers are rarely aware of physically adverse effects as a result of excessive consumption of caffeine. DATA SOURCES A literature search using multiple databases was performed for articles published with concentration on meta-analyses, systematic reviews, and randomized controlled trials. RESULTS Excess coffee consumption is also a risk of primary cardiac arrest especially in young people. Treatment modalities include activated charcoals, beta-blockers, vasopressin and hemodialysis when necessary. CONCLUSION Coffee consumers should be advised not to routinely take more than moderate coffee.
