RESUMO

Our aim was to assess whether long-term adherence to a Mediterranean diet (MedDiet) and leisure-time physical activity (LTPA) were associated with a lower initiation of cardiovascular drug use. We studied the association between cumulative average of MedDiet adherence and LTPA and the risk of cardiovascular drug initiation in older adults at high cardiovascular risk (PREvención con DIeta MEDiterránea trial participants) non-medicated at baseline: glucose-lowering drugs (n = 4437), antihypertensives (n = 2145), statins (n = 3977), fibrates (n = 6391), antiplatelets (n = 5760), vitamin K antagonists (n = 6877), antianginal drugs (n = 6837), and cardiac glycosides (n = 6954). One-point increases in MedDiet adherence were linearly associated with a decreased initiation of glucose-lowering (HR: 0.76 [0.71-0.80]), antihypertensive (HR: 0.79 [0.75-0.82]), statin (HR: 0.82 [0.78-0.85]), fibrate (HR: 0.78 [0.68-0.89]), antiplatelet (HR: 0.79 [0.75-0.83]), vitamin K antagonist (HR: 0.83 [0.74; 0.93]), antianginal (HR: 0.84 [0.74-0.96]), and cardiac glycoside therapy (HR: 0.69 [0.56-0.84]). LTPA was non-linearly related to a delayed initiation of glucose-lowering, antihypertensive, statin, fibrate, antiplatelet, antianginal, and cardiac glycoside therapy (minimum risk: 180-360 metabolic equivalents of task-min/day). Both combined were synergistically associated with a decreased onset of glucose-lowering drugs (p-interaction = 0.04), antihypertensive drugs (p-interaction < 0.001), vitamin K antagonists (p-interaction = 0.04), and cardiac glycosides (p-interaction = 0.01). Summarizing, sustained adherence to a MedDiet and LTPA were associated with lower risk of initiating cardiovascular-related medications.

RESUMO

OBJECTIVE: To examine in older individuals at high cardiovascular risk whether following a Mediterranean diet decreased the necessity of antihypertensive drugs and modulated their associated cardiovascular risk. METHODS: In the PREvención con DIeta MEDiterránea study, we assessed whether volunteers randomly allocated to an intervention with a Mediterranean diet enriched with extra-virgin olive oil or nuts (relative to a low-fat control diet) disclosed differences in the risk of: initiating antihypertensive medication in nonusers at baseline (n = 2188); and escalating therapy in participants using one, two, or three drugs at baseline (n = 2361, n = 1579, and n = 554, respectively). We also assessed whether allocation to Mediterranean diet modified the association between antihypertensive drug use and incident cardiovascular events. RESULTS: Participants allocated to Mediterranean diet interventions were associated with lower risk of initiating antihypertensive therapy [5-year incidence rates: 47.1% in the control diet, 43.0% in MedDiets; hazard ratio = 0.84, 95% CI (0.74--0.97), in a model adjusted for age, sex, and recruitment site]. Volunteers using two drugs at baseline in the Mediterranean diet intervention enriched with extra-virgin olive oil decreased their risk of therapy escalation [5-year incidence rates: 22.9% in the control diet, 20.1% in the MedDiet; hazard ratio = 0.77, 95% CI (0.60--0.99)]. Allocation to Mediterranean diet interventions attenuated the association between antihypertensive therapy at baseline and incidence of major adverse cardiovascular events (P interaction = 0.003). CONCLUSION: In an older population at high cardiovascular risk, following a Mediterranean diet reduced the risk of initiating or escalating antihypertensive medication and attenuated cardiovascular risk in antihypertensive drug users.

RESUMO

Our aim is to assess whether following a Mediterranean Diet (MedDiet) decreases the risk of initiating antithrombotic therapies and the cardiovascular risk associated with its use in older individuals at high cardiovascular risk. We evaluate whether participants of the PREvención con DIeta MEDiterránea (PREDIMED) study allocated to a MedDiet enriched in extra-virgin olive oil or nuts (versus a low-fat control intervention) disclose differences in the risk of initiation of: (1) vitamin K epoxide reductase inhibitors (acenocumarol/warfarin; n = 6772); (2) acetylsalicylic acid as antiplatelet agent (n = 5662); and (3) other antiplatelet drugs (cilostazol/clopidogrel/dipyridamole/ditazol/ticlopidine/triflusal; n = 6768). We also assess whether MedDiet modifies the association between the antithrombotic drug baseline use and incident cardiovascular events. The MedDiet intervention enriched with extra-virgin olive oil decreased the risk of initiating the use of vitamin K epoxide reductase inhibitors relative to control diet (HR: 0.68 [0.46-0.998]). Their use was also more strongly associated with an increased risk of cardiovascular disease in participants not allocated to MedDiet interventions (HRcontrol diet: 4.22 [1.92-9.30], HRMedDiets: 1.71 [0.83-3.52], p-interaction = 0.052). In conclusion, in an older population at high cardiovascular risk, following a MedDiet decreases the initiation of antithrombotic therapies and the risk of suffering major cardiovascular events among users of vitamin K epoxide reductase inhibitors.

RESUMO

BACKGROUND: Hypertension remains the largest attributable risk factor of cardiovascular disease (CVD), and a reduction of cardiovascular events is linked to diminished elevated blood pressure (BP) values. High alcohol intake is a common cause of hypertension, but some studies have suggested that moderate wine consumption may reduce BP and increase plasma nitric oxide (NO) due to its polyphenol content. OBJECTIVE: The aim of the present study was to compare the effects of Andalusian aged white wine (AWW) under a veil of flor, an alcoholic beverage with a moderate polyphenol content, with those of gin, an alcoholic beverage without polyphenols, on BP and plasma NO in men at high cardiovascular risk. METHODS: This study was designed as an open, randomized crossover-controlled trial in which 38 high-risk male volunteers, aged 55 to 80, received 30 g of ethanol daily in the form of AWW or gin. This was carried out over the course of three weeks, after a two-week washout period. At baseline and after each intervention period, BP, anthropometric parameters, and plasma NO were measured; food intake was also recorded, and physical activity was monitored. RESULTS: Compared to gin, AWW significantly reduced systolic and diastolic BP (p ≤ 0.033; both) and increased plasma NO levels (p = 0.013). Additionally, changes in BP values observed after AWW significantly correlated with increases in plasma NO. No changes in food intake, physical activity, body weight, or waist were observed between the two intervention periods. CONCLUSIONS: Moderate daily consumption of AWW may be useful to reduce elevated BP due to an increase of NO synthesis. This effect could be attributed to grape-derived compounds in AWW, such as polyphenols, which are not present in gin.

RESUMO

BACKGROUND: Atherosclerosis is an inflammatory disease. Previous studies have suggested the beneficial effects of moderate consumption of alcoholic beverages on reducing cardiovascular risk (CVR). The aim of this study was to evaluate the effects of acute consumption of Andalusian aged wine (AAW) and gin by analyzing the expression of genes related to the appearance and progression of atherosclerosis in men with high CVR. METHODS: We performed an open, randomized, controlled, crossover trial including 41 men with high CVR between 55 and 80 years age, who received a single dose of AAW or gin (0.5 g ethanol/kg). The expression of 10 genes related to atherosclerosis was determined by RT-PCR at baseline and 4 h after the intervention. RESULTS: Gene expression analysis 4 h after consumption of each alcoholic beverage showed a significant decrease in Toll-like receptors 4 and 6 (TLR4, TLR6) and Caspase-1 (p < 0.05 all). Additionally, TLR2, Interleukin-1 receptor, chemokine receptor 3 and inflammasome expression decreased after AAW intake (p < 0.05, all) while only chemokine receptor 5 decreased after gin consumption (p = 0.039). CONCLUSION: The decrease in the expression of several genes related to the appearance and progression of atherosclerosis was greater after AAW than gin intake, suggesting that the phenolic content of AAW may play a protective role against atherosclerosis.
