Coffee consumption lowers risk of CVD, IHD mortality in MI patients
Drinking coffee, whether caffeinated or decaffeinated, is associated with a reduced risk of cardiovascular disease (CVD) and ischaemic heart disease (IHD) mortality in patients with a prior myocardial infarction (MI), according to a recent study.
In this prospective study, researchers included 4,365 Dutch patients from the Alpha Omega Cohort (aged 60 to 80 years; 21 percent female) who suffered from an MI <10 years before study enrollment. They collected dietary data at baseline (2002 to 2006), including coffee consumption over the past month, with a 203-item validated food-frequency questionnaire.
Causes of death were monitored until 1 January 2013. Multivariable Cox proportional hazard models were used, adjusting for lifestyle and dietary factors, to estimate hazard ratios (HRs) for mortality in categories of coffee consumption.
Of the patients, 96 percent drank coffee, with a median of 375 mL/d (about 3 cups a day) total intake. A total of 945 patients died, including 396 CVD-related and 266 IHD-related deaths, during a median 7.1 years of follow-up.
An inverse association was observed between coffee consumption and CVD mortality, with HRs of 0.69 (95 percent CI, 0.54 to 0.89) for >2 to 4 cups/d and 0.72 (0.55 to 0.95) for >4 cups/d, compared with 0 to 2 cups/d. Corresponding HRs were 0.77 (0.57 to 1.05) and 0.68 (0.48 to 0.95) for IHD-related mortality and 0.84 (0.71 to 1.00) and 0.82 (0.68 to 0.98) for all-cause mortality, respectively.
There were similar associations for decaffeinated coffee and for coffee with additives.
“Consumption of coffee, one of the most popular beverages around the world, has been associated with a lower risk of cardiovascular and all-cause mortality in population-based studies,” according to researchers.
