A Mediterranean weight loss plan was superior to a low-fat weight loss plan in stopping main CV occasions in secondary prevention of CVD, in line with findings from the CORDIOPREV examine.
In a single-center evaluation following greater than 1,000 sufferers assigned to 2 high-intensity weight loss plan interventions for 7 years, researchers additionally discovered the intervention successfully modified the dietary habits for each the Mediterranean and the low-fat weight loss plan teams, leading to vital dietary modifications towards the assigned weight loss plan.
“In males, the Mediterranean weight loss plan confirmed a fair increased superiority than the low-fat weight loss plan, with an almost 33% discount in main cardiovascular occasions,” Javier Delgado-Lista, MD, PhD, of the lipids and atherosclerosis unit at Hospital Universitario Reina Sofia in Cordoba, Spain, and colleagues wrote. “The Mediterranean weight loss plan additionally confirmed increased efficacy within the whole cohort (males and girl) with no household historical past of coronary coronary heart illness, in members with an LDL lower than 100 mg/dL at baseline, in sufferers youthful than age 70 years at examine entry, and people with a dietary adherence of greater than 80% to the assigned weight loss plan all through the examine.”
Outcomes by weight loss plan kind
Delgado-Lista and colleagues analyzed information from 1,002 adults with established CHD (aged 20 to 75 years) randomly assigned to a Mediterranean weight loss plan or a low-fat weight loss plan intervention, with a follow-up of seven years. The imply age was 60 years and 82.5% of members have been males.
Scientific investigators have been masked to remedy task; members weren’t. The first consequence was a composite of main CV occasions, together with MI, revascularization, ischemic stroke, peripheral artery illness and CV demise.
The findings have been printed in The Lancet.
Researchers discovered members in each teams adhered to the 2 diets; the Mediterranean and the low-fat weight loss plan teams additionally elevated their fiber consumption (imply, 2.3 g per 1,000 kcal vs. 3.2 g per 1,000 kcal) on account of a better consumption of greens, fruits and legumes. Individuals in each teams additionally decreased consumption of crimson or processed meats, candy or carbonated drinks and fats spreads.
The first endpoint occurred in 87 members within the Mediterranean weight loss plan group and in 111 within the low-fat group, for a crude charge of 28.1 per 1,000 person-years (95% CI, 27.9-28.3) within the Mediterranean weight loss plan vs. 37.7 per 1,000 person-years (95% CI, 37.5-37.9) within the low-fat group (P = .039).
In all fashions, researchers discovered the Mediterranean weight loss plan was superior to a low-fat weight loss plan.
Adjusted HRs for the first endpoint ranged from 0.719 (95% CI, 0.541-0.957) to 0.753 (95% CI, 0.568-0.998) in favor of the Mediterranean weight loss plan vs. low-fat consuming plan.
“When evaluating the completely different elements of the composite main consequence, we didn’t discover any vital statistical distinction between diets,” the researchers wrote.
When evaluating affected person subgroups, the Mediterranean weight loss plan was superior to the low-fat weight loss plan in members with no household historical past of CHD, in these with out hypertension at baseline, in these youthful than 70 years at examine entry, and people with LDL decrease than 100 mg/dL.
“The truth that main endpoint charges have been decrease than anticipated would possibly help the speculation that the 2 diets had excessive efficacy in stopping cardiovascular recurrences and help the earlier outcomes of research with low-fat weight loss plan vs. management diets or with the Mediterranean weight loss plan in members at excessive danger in main prevention,” the researchers wrote.
Findings vital for males
The researchers additionally famous that the prevalence of the Mediterranean weight loss plan was increased in males, suggesting there was not sufficient energy within the feminine group or that intercourse is an element within the dietary response. Major endpoints occurred in 16.2% of males within the Mediterranean weight loss plan group vs. 22.8% of males within the low-fat weight loss plan group, for an adjusted HR of 0.669 (95% CI, 0.489-0.915; P = .013); nonetheless, there have been no between-group variations for the ladies.
“On this sense, our examine was designed to symbolize the inhabitants with ischemic coronary heart illness and all sufferers who met the recruitment standards have been included, no matter intercourse,” the researchers wrote. “Future research ought to be created with enough energy to unveil particular sex-related results in ladies.”
