Aims: We examined the hypothesis that high adherence to a Mediterranean diet reduces the risk of developing heart failure (HF) as well as the risk of death from HF.Methods and Results: The study population comprised 37 308 men from the Cohort of Swedish Men who were free from cardiovascular disease at baseline. The modified Mediterranean diet (mMED) score was created from a self-administered food frequency questionnaire, based on consumption of presumed beneficial/detrimental foods, on a 0-8 scale. Incident HF events were ascertained by linkage to the Swedish National Patient and the Cause of Death Registers. Relative risks (RR) with 95% confidence intervals (CI), adjusted for potential confounders, were estimated by Cox proportional hazards regression models. We identified 146 deaths from HF and 1269 incident HF events over a median follow-up of 10.9 years (1998-2008). The mMED score was inversely associated with risk of HF (multivariable RR for the highest vs. lowest quartile 0.69, 95% CI 0.57, 0.83); the corresponding RR of HF mortality was 0.55 (95% CI 0.31, 0.98). The multivariable RR for every two-point increment in the mMED score was 0.85 (95% CI 0.78, 0.91) for incidence of HF and 0.78 (95% CI 0.62, 0.98) for mortality from HF, respectively.Conclusions: High adherence to a Mediterranean diet was associated with a lower risk of HF and mortality from HF in men. Further studies are needed to replicate these findings in other populations. [ABSTRACT FROM AUTHOR]

Beneficial effects of Mediterranean diet (MD) have been consistently documented. However, to fully understand the public health implications of MD adherence, an informative step is to quantify these effects in terms of survival time differences. The aim of this study was to evaluate the impact of MD on survival, presenting results in terms of differences in median age at death. We used data from 71,333 participants from a large population-based cohort of Swedish men and women, followed-up between January 1, 1998, and December 31, 2012. A total score of MD, ranging from 0 to 8, was calculated by including information on vegetables and fruits consumption, legumes and nuts, non-refined/high fiber grains, fermented dairy products, fish, red meat, use of olive oil/rapeseed oil, and moderate alcohol intake. Multivariable-adjusted differences in median age at death were estimated with Laplace regression and presented as a function of the MD score. During 15 years of follow-up we documented 14,697 deaths. We observed a linear dose-response association between the MD score and median age at death, with higher score associated with longer survival. The difference in median age at death between participants with the extreme scores (0 vs 8) of MD was up to 2 years (23 months, 95 % CI: 16-29). In this study we documented that adherence to MD may accrue benefits up to 2 years of longer survival.

Background and Aims: The Mediterranean diet, which is palatable and easily achievable, has been associated with lower all-cause and cardiovascular disease (CVD) incidence and mortality. Data on heart failure (HF) and stroke types are lacking. The aim was to examine a Mediterranean diet in relation to incidence of myocardial infarction (MI), HF and stroke types in a Swedish prospective cohort., Methods: In a population-based cohort of 32,921 women, diet was assessed through a self-administered questionnaire. The modified Mediterranean diet (mMED) score was created based on high consumption of vegetables, fruits, legumes, nuts, whole grains, fermented dairy products, fish and monounsaturated fat, moderate intakes of alcohol and low consumption of red meat, on a 0-8 scale. Relative risks (RR) with 95% confidence intervals (CI), adjusted for potential confounders, were estimated by Cox proportional hazards regression models., Results: During 10 y of follow-up (1998-2008), 1109 MIs, 1648 HFs, 1270 ischemic strokes and 262 total hemorrhagic strokes were ascertained. A high adherence to the mMED score (6-8), compared to low, was associated with a lower risk of MI (RR: 0.74, 95% CI: 0.61-0.90, p = 0.003), HF (RR: 0.79, 95% CI: 0.68-0.93, p = 0.004) and ischemic stroke (RR: 0.78, 95% CI: 0.65-0.93, p = 0.007), but not hemorrhagic stroke (RR: 0.88, 95% CI: 0.61-1.29, p = 0.53)., Conclusions: Better adherence to a Mediterranean diet was associated with lower risk of MI, HF and ischemic stroke. The Mediterranean diet is most likely to be beneficial in primary prevention of all major types of atherosclerosis-related CVD., (Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.)
