Moderate coffee consumption can reduce risk of heart failure
Coffee is the most favourite brew lovers around the world who reach for their favorite morning brew probably aren’t thinking about its health benefits or risks. And yet this beverage has been subject to a long history of debate. Several studies suggests that when consumed in moderation, coffee can be considered a healthy beverage.
Congestive heart failure, or heart failure (HF), is a long-term condition that’s a serious cause of death, and coffee consumption is long related to cardiovascular diseases.
A study in Nutrition, Metabolism and Cardiovascular diseases journal reveals that a large cohort in UK were moderate coffee intake could reduce the risk of HF, but excessive coffee intake has no such effect, the impact of consuming more than6 cups/day of coffee on HF was not statistically significant. Different types of coffee have different effects on HF incidence and ground coffee can greatest reduces the risk of HF.
Researchers obtained Data from the UK Biobank, comprising 497,503 adults (age, 56.5±8.1 years; 54.6% women) who were free from HF at baseline in 2006–2010. The median follow-up time for the HF incidence was 11.9 years. Marginal structural models (MSM) were employed to adjust for potential time-varying confounders and account for bias caused by loss of follow-up. Furthermore, they used a restricted cubic spline to test and describe the nonlinear relationship between coffee consumption and HF risk.
The key findings of the study are
• At baseline, 70.5% of participants reported drinking ≥1 cups/d coffee and 2.7% participants developed HF.
• After adjusting for potential confounders, we identified a nonlinear J-shaped association between coffee consumption and HF risk (P<0.001).
• Compared with drinking coffee <1 cups/d, 1–2 cups/d (HR=0.878; 95% CI: 0.838–0.920), 3–4 cups/d (HR=0.920; 95% CI: 0.869–0.974) may be associated with a reduced risk of HF, while >6 cups/d (HR=1.209; 95% CI: 1.056–1.385) may be associated with a higher risk of HF.
• However, sensitive analyses stratified by gender and smoking status indicated that >6 cups/d does not significantly increase the risk of HF.
• Additionally, the type of coffee was found to significant impact on the incidence of HF (P<0.05).
Qiang Han and team concluded that In this large cohort of UK adults, moderate coffee consumption may reduce risk of HF incidence.
