Brown OI, et al. – This study's purpose was to explore whether coffee consumption influenced mortality after acute myocardial infarction (AMI). It was concluded that drinking coffee habitually following AMI was connected with a lessened risk of mortality.

Methods

• In this study, the researchers carried out a dose–response meta-analysis of prospective studies that inspected the affiliation between coffee intake and mortality after an AMI.
• Utilizing a defined-search strategy, electronic databases (MEDLINE and Embase) were searched for papers published somewhere around 1946 and 2015.
• 2 eligible studies investigating post-AMI mortality risk against coffee consumption were distinguished and assessed utilizing set criteria.    
• Combined, these studies enlisted a sum of 3271 patients and 604 passed on.  
•  The hazard ratios for the following experimental groups were characterized: light coffee drinkers (1–2 cups/day) versus noncoffee drinkers, heavy coffee drinkers (>2 cups/day) versus noncoffee drinkers and heavy coffee drinkers versus light coffee drinkers.

Results

• Researchers found that a statistically significant inverse correlation was observed between coffee drinking and mortality; all 3 groups demonstrated a significant reduction in risk ratio.
• They added that light coffee drinkers versus noncoffee drinkers were connected with a risk ratio of 0.79 [95% confidence interval (CI): 0.66–0.94, P=0.008]; heavy coffee drinkers versus noncoffee drinkers were connected with a risk ratio of 0.54 (95% CI: 0.45–0.65, P<0.00001); and heavy coffee drinkers versus light coffee drinkers were connected with a risk ratio of 0.69 (95% CI: 0.58–0.83, P<0.0001).
