van Dongen LH, et al. – This
prospective investigation assessed the link between coffee consumption
(caffeinated and decaffeinated) and cardiovascular disease (CVD)
mortality, ischemic heart disease (IHD) mortality, and all–cause
mortality, respectively, in patients with a previous experience of
myocardial infarction (MI). Researchers concluded drinking coffee,
either caffeinated or decaffeinated, may lower the risk of CVD and IHD
mortality in patients with a prior MI.
Methods
- This study included 4365 Dutch patients from the Alpha Omega Cohort who were aged 60–80 y (21% female) and had experienced an MI <10 y before study enrollment.
- Using a 203-item validated food-frequency questionnaire, dietary data including coffee consumption over the past month was collected, at baseline (2002–2006).
- Until 1 January 2013, researchers monitored causes of death.
- They obtained HRs for mortality in categories of coffee consumption from multivariable Cox proportional hazard models, adjusting for lifestyle and dietary factors.
Results
- Findings revealed that most patients (96%) drank coffee, and the median total coffee intake was 375 mL/d (~3 cups/d).
- Data reported that during a median follow-up of 7.1 y, a total of 945 deaths occurred, including 396 CVD-related and 266 IHD-related deaths.
- Researchers observed that coffee consumption was inversely associated with CVD mortality, with HRs of 0.69 (95% CI: 0.54, 0.89) for >2–4 cups/d and 0.72 (0.55, 0.95) for >4 cups/d, compared with 0–2 cups/d.
- In addition, results highlighted that corresponding HRs were 0.77 (95% CI: 0.57, 1.05) and 0.68 (95% CI: 0.48, 0.95) for IHD mortality and 0.84 (95% CI: 0.71, 1.00) and 0.82 (95% CI: 0.68, 0.98) for all-cause mortality, respectively.
- They also found similar associations for decaffeinated coffee and for coffee with additives.
