Abstract
Although a light to moderate alcohol intake is associated with a lower risk of acute coronary syndrome (ACS), alcohol is also associated with risk of hypertension, which in turn is a strong risk factor of ACS. We examined whether middle-aged men and women with hypertension also benefit from a light to moderate alcohol intake in relation to risk of ACS and overall mortality. We used data from 57,053 men and women, aged 50-64, who participated in the Danish Diet, Cancer and Health study. Information on alcohol intake (amount and frequency) was reported by the participants. Hypertension status was assessed at baseline by combining blood pressure measurements and self-reports. During follow-up, 860 and 271 ACS events occurred among men and women. Irrespective of alcohol intake, participants with hypertension had a higher risk than participants with normal blood pressure. Alcohol intake was associated with a lower risk of ACS among participants both with and without hypertension and there was no evidence of interaction between alcohol intake and hypertension. Those who drank moderately had a lower mortality than abstainers and those who drank heavily; and for all levels of alcohol intake, participants with hypertension had a higher risk than participants with normal blood pressure. Results were similar for men and women. These findings indicate that a light to moderate alcohol intake has similar effects on the risk of ACS in men and women with and without hypertension.

Abstract
The prevalence of hypertension has increased over the past decade in many developed and developing countries, including China. This increase may be associated with changes in lifestyle, including dietary patterns. We evaluated the association of dietary patterns with blood pressure (BP) by using data from a large, population-based cohort study of middle-aged and elderly Chinese men, the Shanghai Men's Health Study. The present cross-sectional analysis includes 39 252 men who reported no prior history of hypertension, diabetes, CHD, or stroke nor use of antihypertensive drugs at study enrolment. Three dietary patterns, 'vegetable', 'fruit and milk' and 'meat', were derived using factor analysis. The fruit and milk diet was inversely associated with both systolic and diastolic BP (Ptrend < 0.001). The adjusted mean systolic BP was 2.9 mmHg lower (95 % CI - 3.4, - 2.4), and diastolic BP was 1.7 mmHg lower (95 % CI - 2.0, - 1.4) for men in the highest quintile of the 'fruit and milk' pattern compared with men in the lowest quintile. This inverse association was more evident among heavy drinkers; the highest quintile of the 'fruit and milk' pattern was associated with a 4.1 mmHg reduction in systolic BP v. a 2.0 mmHg reduction among non-drinkers (Pinteraction = 0.003) compared to the lowest quintile. The corresponding reductions in diastolic BP were 2.0 v. 1.3 mmHg (Pinteraction = 0.011). The 'fruit and milk' pattern was associated with a lower prevalence of both pre-hypertension and hypertension, and the associations appeared to be stronger among drinkers. Results of the present study suggest an important role for diet in the prevention of hypertension.

Abstract
Research on how alcohol consumption influences the structure and blood supply of the brain has generally focused on two primary areas of interest: the atrophic effect of heavy drinking on brain structure and the effects of moderate and heavy drinking on the risk of stroke. Heavy alcohol consumption results in atrophy of gray and white matter, particularly in the frontal lobes, cerebellum, and limbic structures. Heavy drinking also raises the risk of ischemic and hemorrhagic stroke, while light drinking is associated with a lower risk of ischemic stroke. Recently, the author and his colleagues studied alcohol consumption and prevalence of subclinical abnormalities detected by magnetic resonance imaging of the brain among 3376 older adults enrolled in the Cardiovascular Health Study. They found that alcohol consumption was positively associated with measures of brain atrophy and inversely associated with subclinical infarcts in a dose-dependent manner. Alcohol consumption and white matter lesions had a U-shaped relationship, with the lowest prevalence among those who consumed 1-6 drinks per week. Further research is needed to determine how these associations interact to influence overall brain function.

Abstract
High blood pressure (BP) is a major health problem in the US, affecting more than 50 million people. Although high BP is among the most common reasons for outpatient visits, BP control is often inadequate. It is well established that BP can be lowered pharmacologically in hypertensive individuals; however, anti-hypertensive medications are not effective for everyone, and may be costly and result in adverse effects that impair quality of life and reduce adherence. Moreover, abnormalities associated with high BP, such as insulin resistance and hyperlipidaemia, may persist or may even be exacerbated by some anti-hypertensive medications. Consequently, there has been a great deal of interest in the development and application of behavioural interventions in the management of high BP. The main behavioural interventions that are recommended to reduce BP are exercise and the Dietary Approaches to Stop Hypertension (DASH) diet. Weight loss is also recommended for BP reduction in overweight individuals. Exercise alone is associated with reductions of approximately 3.5 and 2.0mm Hg in systolic (SBP) and diastolic blood pressure (DBP), respectively. Patients fed a DASH diet (a diet high in low-fat dairy products and fibre, including fruits and vegetables) had reductions in SBP and DBP of 5.5 and 3.0mm Hg, respectively, compared with those consuming a standard US diet. Reductions of approximately 8.5mm Hg SBP and 6.5mm Hg DBP accompany weight loss of 8 kg. In overweight hypertensive patients, a combined exercise and weight-loss intervention has been shown to decrease SBP and DBP by 12.5 and 7.9 mm Hg, respectively. There is evidence to suggest that these decreases in BP are associated with improvements in left ventricular structure and function, and peripheral vascular health. Both exercise training and weight loss have been shown to decrease left ventricular mass and wall thickness, reduce arterial stiffness and improve endothelial function. These data support the role of behavioural interventions in the treatment of patients with elevations in BP.
