Abstract
BACKGROUND Alcohol consumption has been associated with higher blood pressure and an increased risk of hypertension. However, the possible exposure thresholds and effect-modifiers are uncertain. METHODS We assessed the dose-response relationship between usual alcohol intake and hypertension incidence in nonexperimental cohort studies. After performing a systematic literature search through February 20, 2024, we retrieved 23 eligible studies. We computed risk ratios and 95% CI of hypertension incidence using a nonlinear meta-analytic model based on restricted cubic splines, to assess the dose-response association with alcohol consumption. RESULTS We observed a positive and almost linear association between alcohol intake and hypertension risk with risk ratios of 0.89 (0.84-0.94), 1.11 (1.07-1.15), 1.22 (1.14-1.30), and 1.33 (1.18-1.49) for 0, 24, 36 and 48 g/d, respectively, using 12 g alcohol/d as the reference value. In sex-specific analyses, the association was almost linear in men over the entire range of exposure but only observed above 12 g/d in women, although with a steeper association at high levels of consumption compared with men. The increased risk of hypertension above 12 to 24 g alcohol/d was similar in Western and Asian populations and considerably greater in White than in Black populations, mainly due to the positive association in women at moderate-to-high intake. CONCLUSIONS Overall, our results lend support to a causal association between alcohol consumption and risk of hypertension, especially above an alcohol intake of 12 g/d, and are consistent with recommendations to avoid or limit alcohol intake. Sex and ethnicity appear to be major effect-modifiers of such association.

Vascular injury associated with ethanol intake is driven by AT1 receptor and mitochondrial dysfunction. Biomed Pharmacother 2023; 169:115845. [PMID: 37951022 DOI: 10.1016/j.biopha.2023.115845] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2023] [Revised: 10/27/2023] [Accepted: 11/05/2023] [Indexed: 11/13/2023] Open
Abstract
BACKGROUND Renin-angiotensin (Ang II)-aldosterone system (RAAS) is crucial for the cardiovascular risk associated with excessive ethanol consumption. Disturbs in mitochondria have been implicated in multiple cardiovascular diseases. However, if mitochondria dysfunction contributes to ethanol-induced vascular dysfunction is still unknown. We investigated whether ethanol leads to vascular dysfunction via RAAS activation, mitochondria dysfunction, and mitochondrial reactive oxygen species (mtROS). METHODS Male C57/BL6J or mt-keima mice (6-8-weeks old) were treated with ethanol (20% vol./vol.) for 12 weeks with or without Losartan (10 mg/kg/day). RESULTS Ethanol induced aortic hypercontractility in an endothelium-dependent manner. PGC1α (a marker of biogenesis), Mfn2, (an essential protein for mitochondria fusion), as well as Pink-1 and Parkin (markers of mitophagy), were reduced in aortas from ethanol-treated mice. Disturb in mitophagy flux was further confirmed in arteries from mt-keima mice. Additionally, ethanol increased mtROS and reduced SOD2 expression. Strikingly, losartan prevented vascular hypercontractility, mitochondrial dysfunction, mtROS, and restored SOD2 expression. Both MnTMPyP (SOD2 mimetic) and CCCP (a mitochondrial uncoupler) reverted ethanol-induced vascular dysfunction. Moreover, L-NAME (NOS inhibitor) and EUK 134 (superoxide dismutase/catalase mimetic) did not affect vascular response in ethanol group, suggesting that ethanol reduces aortic nitric oxide (NO) and H2O2 bioavailability. These responses were prevented by losartan. CONCLUSION AT1 receptor modulates ethanol-induced vascular hypercontractility by promoting mitochondrial dysfunction, mtROS, and reduction of NO and H2O2 bioavailability. Our findings shed a new light in our understanding of ethanol-induced vascular toxicity and open perspectives of new therapeutic approaches for patients with disorder associated with abusive ethanol drinking.

Abstract
Consumption of high amounts of ethanol is a risk factor for development of cardiovascular diseases such as arterial hypertension. The hypertensive state induced by ethanol is a complex multi-factorial event, and oxidative stress is a pathophysiological hallmark of vascular dysfunction associated with ethanol consumption. Increasing levels of reactive oxygen species (ROS) in the vasculature trigger important processes underlying vascular injury, including accumulation of intracellular Ca2+ ions, reduced bioavailability of nitric oxide (NO), activation of mitogen-activated protein kinases (MAPKs), endothelial dysfunction, and loss of the anticontractile effect of perivascular adipose tissue (PVAT). The enzyme nicotinamide adenine dinucleotide phosphate (NADPH) oxidase plays a central role in vascular ROS generation in response to ethanol. Activation of the renin-angiotensin-aldosterone system (RAAS) is an upstream mechanism which contributes to NADPH oxidase stimulation, overproduction of ROS, and vascular dysfunction. This review discusses the mechanisms of vascular dysfunction induced by ethanol, detailing the contribution of ROS to these processes. Data examining the association between neuroendocrine changes and vascular oxidative stress induced by ethanol are also reviewed and discussed. These issues are of paramount interest to public health as ethanol contributes to blood pressure elevation in the general population, and it is linked to cardiovascular conditions and diseases.

Abstract
A large percentage of obese patients in the United States suffer a comorbid substance use disorder, mainly alcohol use. Alcohol consumption interferes with the absorption of dietary methyl donors such as folate required for the one-carbon metabolism pathway and subsequently for DNA methylation. In this study, we assessed the association between alcohol consumption and DNA methylation in obese subjects. We obtained visceral adipose tissue (VAT) biopsies from bariatric patients. DNA methylation of 94 genes implicated in inflammation and immunity were analyzed in VAT in relation to alcohol consumption data obtained via questionnaires. Vasoreactivity was measured in the brachial artery and the VAT-isolated arterioles. Pro-inflammatory genes were significantly hypomethylated in the heavy drinking category correlating with higher levels of circulating inflammatory cytokines. Alcohol consumption correlated positively with body mass index (BMI), fat percentage, insulin resistance, impaired lipid profile, and systemic inflammation and negatively with plasma folate and vitamin B12, inflammatory gene DNA methylation, and vasoreactivity. In conclusion, these data suggest that alcohol intake is associated with lower DNA methylation and higher inflammation and cardiometabolic risk in obese individuals.

Abstract
Epidemiological studies have established the association between excessive alcohol consumption and systemic hypertension (SH). However, there are conflicting reports of the association of low to moderate alcohol consumption with SH. The objective of the study was to examine the associations of alcohol consumption and blood pressure categories using the 2017 American College of Cardiology/American Heart Association high blood pressure guidelines. This analysis included 17,059 participants from the Third National Health and Nutrition Examination Survey. Alcohol consumption was ascertained by way of a questionnaire. Blood pressure (mm Hg) was measured during the in-home interview and the participant's visit to the mobile examination center. We used multivariable logistic regression models to examine cross-sectional associations of alcohol consumption and blood pressure categories based on new American College of Cardiology/American Heart Association High Blood Pressure guidelines. Models were adjusted for age, gender, income, and cardiovascular risk factors. Compared with never drinkers, moderate drinkers (7 to 13 drinks/week) had increased odds of prevalent stage 1 and stage 2 SH (odds ratio [95% confidence interval] 1.51 [1.22 to 1.87] and 1.55 [1.20 to 2.00]). Similarly, there were significantly higher odds of prevalent stage 1 and stage 2 SH among heavy drinkers (≥14 drinks/week) (odds ratio [95% confidence interval] 1.65 [1.33 to 2.05] and 2.46 [1.93 to 3.14]). We did not find any association between alcohol consumption and elevated blood pressure category. Response bias must be considered because alcohol consumption was self-reported. Our study indicates the need for further research to understand the potential mechanisms by which alcohol consumption increases the risk of SH. In conclusion, this analysis from a population-based survey showed an association between moderate and heavy alcohol consumption and a higher prevalence of SH.

Abstract
Background We aimed to investigate the association between alcohol drinking patterns and the presence of impaired fasting glucose (IFG) and diabetes mellitus (DM). Methods We used data from the Korean National Health and Nutrition Examination Survey, 2010–2014. The participants were aged ≥30 years and had no previous diagnosis of DM. High-risk drinking was defined as alcohol consumption of ≥7 glasses at a sitting for men, and ≥5 glasses for women. After adjusting for confounding factors, a polychotomous logistic regression analysis was performed to assess the association of drinking patterns with IFG and DM. Results For men, high-risk drinking was associated with higher odds ratios (ORs) of IFG (2–4/month, OR 1.51; 95% confidence interval [CI], 1.13–2.04; 2–3/week, OR 1.79; 95% CI, 1.38–2.33; and ≥4/week, OR 2.24; 95% CI, 1.65–3.03) and of DM (2–4/month, OR 2.12; 95% CI, 1.20–3.77; 2–3/week, OR 1.78; 95% CI, 1.05–3.03; and ≥4/week, OR 2.98; 95% CI, 1.72–5.17). For women, high-risk drinking was associated with higher risk of IFG (2–4/month, OR 1.51; 95% CI, 1.04–2.21; 2–3/week, OR 3.19; 95% CI, 2.20–4.64; and ≥4/week, OR 2.23; 95% CI, 1.23–4.06), but not of DM, compared with non-high-risk drinkers who consumed alcohol ≤1 day/month. Non-high-risk drinkers who consumed alcohol ≥4 days/week had higher ORs of DM in men, but lower ORs of DM in women compared with non-high risk drinkers who consumed alcohol ≤1 day/month. Conclusions Compared with non-high-risk alcohol drinking, even occasional high-risk alcohol drinking was associated with a higher risk of IFG in men and women, and DM in men. Nearly daily non-high-risk alcohol drinking was associated with a higher risk of DM in men and lower risk of DM in women.

Abstract
OBJECTIVE To analyze the dose-risk relationship for alcohol consumption and intracerebral hemorrhage (ICH) in the Ethnic/Racial Variations of Intracerebral Hemorrhage (ERICH) study. METHODS ERICH is a multicenter, prospective, case-control study, designed to recruit 1,000 non-Hispanic white patients, 1,000 non-Hispanic black patients, and 1,000 Hispanic patients with ICH. Cases were matched 1:1 to ICH-free controls by age, sex, race/ethnicity, and geographic area. Comprehensive interviews included questions regarding alcohol consumption. Patterns of alcohol consumption were categorized as none, rare (<1 drink per month), moderate (≥1 drink per month and ≤2 drinks per day), intermediate (>2 drinks per day and <5 drinks per day), and heavy (≥5 drinks per day). ICH risk was calculated using the no-alcohol use category as the reference group. RESULTS Multivariable analyses demonstrated an ordinal trend for alcohol consumption: rare (odds ratio [OR] 0.57, p < 0.0001), moderate (OR 0.65, p < 0.0001), intermediate (OR 0.82, p = 0.2666), and heavy alcohol consumption (OR 1.77, p = 0.0003). Subgroup analyses demonstrated an association of rare and moderate alcohol consumption with decreased risk of both lobar and nonlobar ICH. Heavy alcohol consumption demonstrated a strong association with increased nonlobar ICH risk (OR 2.04, p = 0.0003). Heavy alcohol consumption was associated with significant increase in nonlobar ICH risk in black (OR 2.34, p = 0.0140) and Hispanic participants (OR 12.32, p < 0.0001). A similar association was not found in white participants. CONCLUSIONS This study demonstrated potential protective effects of rare and moderate alcohol consumption on ICH risk. Heavy alcohol consumption was associated with increased ICH risk. Race/ethnicity was a significant factor in alcohol-associated ICH risk; heavy alcohol consumption in black and Hispanic participants poses significant nonlobar ICH risk.

Abstract
OBJECTIVES Tea has long been hypothesized to possess hypotensive effects. However, there is uncertainty regarding the association of tea consumption with arterial blood pressure (BP). We aimed to examine the association between tea consumption and BP components including systolic BP (SBP) and diastolic BP (DBP). DESIGN Community-based, cross-sectional study of Suzhou City, Jiangsu Province, China. SETTING Tea consumption has protective influence on BP and presence of hypertension. PARTICIPANTS 4579 older adults aged 60 years or older from the Weitang Geriatric Diseases study. MEASUREMENTS Detailed information regarding tea consumption was collected using a pre-designed questionnaire. BP components were measured at least 3 times with a minimum 5-minute interval, by well-trained research nurses. METHODS Data of 4579 older adults (response rate: 82%) aged 60 years or older from the Weitang Geriatric Diseases study were included in the analysis and we estimated the relationship of tea consumption and BP using linear regression models and the association between tea consumption and risk of hypertension using logistic regression models. RESULTS In linear regression models, higher tea consumption frequency was found to be associated with lower systolic BP values, after adjusting for the effect of age, sex, education level, lifestyle-related factors, and cardiometabolic confounding factors in overall (coefficient =-1.49, P=0.0003), normotensive (coefficient =-0.91, P=0.017) and participants without anti-hypertensive treatment (coefficient =-1.26, P=0.027). Significant inverse association between diastolic BP and frequency of tea consumption was also observed in the overall subjects (coefficient =-0.74, P=0.003). In multivariate logistic analyses, habitual tea drinking was inversely associated with presence of hypertension [odds ratio (OR)=0.79, P=0.011] , and there was a progressive reduction in risk associated with higher frequency of tea consumption (P for trend=0.011). CONCLUSION Habitual tea consumption was found to be associated with lower values of components of BP and a reduced likelihood of having hypertension in older adults. Given the widespread consumption of tea throughout China and the world, together with the major cardiovascular disease risk, our findings have important implications for human health.

Abstract
BACKGROUND Older adults can experience unfavorable health effects from drinking at relatively low consumption levels because of age-related physiological changes and alcohol's potentially adverse interactions with declining health, increased medication-use and diminishing functional status. At the same time, alcohol use in older adults may be protective against heart disease, stroke, and other disorders associated with aging. We developed "A Toast to Health in Later Life! Wise Drinking as We Age," a web-based educational intervention to teach older adults to balance drinking risks and benefits. OBJECTIVE To examine the intervention's feasibility in a sample of community-dwelling current drinkers ≥55 years of age and examine its effects on their quantity and frequency of alcohol use, adherence to standard drinking guidelines, and alcohol-related risks. METHODS Participants were recruited in person, by mail and by telephone between September and October 2014 from a community-based social services organization serving Los Angeles County. Once enrolled, participants were randomly assigned to the intervention or to a control group. The conceptual frameworks for the intervention were the Health Belief Model, models of adult learning, and the US Department of Health and Human Services guidelines for designing easy-to-use websites. The intervention's content focuses on the relationship between drinking and its effects on older adults' medical conditions, use of medications, and ability to perform daily activities. It also addresses quantity and frequency of alcohol use, drinking and driving and binge drinking. The control group did not receive any special intervention. Data on alcohol use and risks for both groups came from the online version of the Alcohol-Related Problems Survey and were collected at baseline and four weeks later. Data on usability were collected online from the intervention group immediately after it completed its review of the website. RESULTS The 49 intervention and 47 control participants did not differ at baseline in age, ethnicity, medication use, medical conditions, or alcohol use and both groups were mostly female, college-educated, and in good health. Of the intervention participants, 94% (46/49) had little or no difficulty using the website, with 67% (33/49) reporting that they will change the way they think about drinking because of their exposure to the education. At the 4-week follow-up, the intervention group reported drinking less (P=.02). No changes between groups were found in quantity and frequency, adherence to recommended guidelines, or risk status. CONCLUSIONS Community-dwelling older adults are receptive to online alcohol education. To be most effective, the education should be included as a component of a larger effort consisting of screening and counseling preferably in a health care setting.

Abstract
For centuries, multiple medical risks of heavy alcohol drinking have been evident with simultaneous awareness of a less harmful or sensible drinking limit. The increased risks of heavy drinking, defined as three or more standard-sized drinks per day, are both cardiovascular (CV) and non-CV. The CV risks include the following: (i) alcoholic cardiomyopathy (ACM), (ii) systemic hypertension, (iii) atrial arrhythmias, (iv) haemorrhagic stroke and, probably, ischaemic stroke. By contrast, modern epidemiological studies have shown lower morbidity and mortality amongst light-moderate drinkers, due mostly to a reduced risk of coronary artery disease (CAD), with contributions from ischaemic stroke and heart failure (HF). A low level of alcohol drinking has no clear relation to increased risk of any CV condition, except for haemorrhagic stroke. There is good evidence that supports the existence of mechanisms by which alcohol might protect against CAD, but the mechanisms for other alcohol-CV associations remain unclear. Interrelationships amongst the CV conditions affect the individual alcohol-disease relationships; for example, lower CAD risk in light-moderate drinkers is to a large extent responsible for the reduced HF risk. International comparison data plus the presence of proposed beneficial nonalcohol components in wine (particularly in red wine) suggest that this beverage type might afford extra CAD protection. However, the effect of beverage choice is confounded by a healthier drinking pattern and more favourable risk traits in wine drinkers. Debate persists about methodological and public health issues related to the epidemiology of alcohol-related CV disease.

Abstract
Intracerebral hemorrhage (ICH) is a very complex pathology, with many different not fully elucidated etiologies and prognostics. It is the most severe subtype of stroke, with high mortality and morbidity rates. Unfortunately, despite the numerous promising preclinical assays including neuroprotective, anti-hypertensive, and anti-inflammatory drugs, to this moment only symptomatic treatments are available, motivating the search for new alternatives. In this context, stem cell therapy emerged as a promising tool. However, more than a decade has passed, and there is still much to be learned not only about stem cells, but also about ICH itself, and how these two pieces come together. To date, rats have been the most widely used animal model in this research field, and there is much more to be learned from and about them. In this review, we first summarize ICH epidemiology, risk factors, and pathophysiology. We then present different methods utilized to induce ICH in rats, and examine how accurately they represent the human disease. Next, we discuss the different types of stem cells used in previous ICH studies, also taking into account the tested transplantation sites. Finally, we summarize what has been achieved in assays with stem cells in rat models of ICH, and point out some relevant issues where attention must be given in future efforts.

Abstract
OBJECTIVES We hypothesized that chronic ethanol intake enhances vascular oxidative stress and induces hypertension through renin-angiotensin system (RAS) activation. METHODS AND RESULTS Male Wistar rats were treated with ethanol (20% v/v). The increase in blood pressure induced by ethanol was prevented by losartan (10mg/kg/day; p.o. gavage), a selective AT1 receptor antagonist. Chronic ethanol intake increased plasma renin activity (PRA), angiotensin converting enzyme (ACE) activity, plasma angiotensin I (ANG I) and angiotensin II (ANG II) levels and serum aldosterone levels. No differences on plasma osmolality and sodium or potassium levels were detected after treatment with ethanol. Ethanol consumption did not alter ACE activity, as well as the levels of ANG I and ANG II in the rat aorta or mesenteric arterial bed (MAB). Ethanol induced systemic and vascular oxidative stress (aorta and MAB) and these effects were prevented by losartan. The decrease on plasma and vascular nitrate/nitrite (NOx) levels induced by ethanol was prevented by losartan. Ethanol intake did not alter protein expression of ACE, AT1 or AT2 receptors in both aorta and MAB. Aortas from ethanol-treated rats displayed decreased ERK1/2 phosphorylation and increased protein expression of SAPK/JNK. These responses were prevented by losartan. MAB from ethanol-treated rats displayed reduced phosphorylation of p38MAPK and ERK1/2 and losartan did not prevent these responses. CONCLUSIONS Our study provides novel evidence that chronic ethanol intake increases blood pressure, induces vascular oxidative stress and decreases nitric oxide (NO) bioavailability through AT1-dependent mechanisms.

Abstract
Excessive ethanol consumption affects virtually any organ, both by indirect and direct mechanisms. Considerable research in the last two decades has widened the knowledge about the paramount importance of proinflammatory cytokines and oxidative damage in the pathogenesis of many of the systemic manifestations of alcoholism. These cytokines derive primarily from activated Kupffer cells exposed to Gram-negative intestinal bacteria, which reach the liver in supra-physiological amounts due to ethanol-mediated increased gut permeability. Reactive oxygen species (ROS) that enhance the inflammatory response are generated both by activation of Kupffer cells and by the direct metabolic effects of ethanol. The effects of this increased cytokine secretion and ROS generation lie far beyond liver damage. In addition to the classic consequences of endotoxemia associated with liver cirrhosis that were described several decades ago, important research in the last ten years has shown that cytokines may also induce damage in remote organs such as brain, bone, muscle, heart, lung, gonads, peripheral nerve, and pancreas. These effects are even seen in alcoholics without significant liver disease. Therefore, alcoholism can be viewed as an inflammatory condition, a concept which opens the possibility of using new therapeutic weapons to treat some of the complications of this devastating and frequent disease. In this review we examine some of the most outstanding consequences of the altered cytokine regulation that occurs in alcoholics in organs other than the liver.

Abstract
OBJECTIVE The purpose of the present study was to determine the impact of alcohol consumption on the incidence of hypertension. METHODS A total of 32,389 male coal mine workers from Kailuan Coal Group in northern China (Kailuan study), free of hypertension, myocardial infarction, stroke, transient ischemia attack and cancer, were followed up every 2 years for 4 years. The average alcohol intake during the past year was reported as baseline. RESULTS During 4 years of follow-up, 9151 out of 32,389 workers developed hypertension categorically. At the end of the follow-up, the cumulative incidence of hypertension in relation to daily alcoholic intake of none, 1-24, 25-49, 50-99, 100-149 and at least 150 g was 25.03, 28.82, 30.10, 37.07, 40.14 and 42.49%, respectively. After adjusting for age, we found that the relative risk of hypertension in those who were never exposed to alcohol was the lowest, with the group 25-49 g/day being the next. This trend was unchanged after adjustment for age, exercise, smoking status, job type and salt intake. After further adjustment for BMI, history of high cholesterol and diabetes mellitus, a positive, linear association between alcohol consumption and the risk of hypertension was found. Models stratified by baseline SBP (<120 and 120-139 mmHg) or DBP (<80 and 80-89 mmHg) did not alter the trend. CONCLUSION The Kailuan study demonstrates that long-term alcohol intake is an independent risk factor of incident hypertension in a large cohort of coal mine workers. Even light-to-moderate alcohol consumption increases the risk of incident hypertension.

Abstract
Epidemiological, preclinical and clinical studies established the association between high alcohol consumption and hypertension. However the mechanism through which alcohol raises blood pressure remains elusive. Several possible mechanisms have been proposed such as an imbalance of the central nervous system, impairment of the baroreceptors, enhanced sympathetic activity, stimulation of the renin-angiotensin-aldosterone system, increased cortisol levels, increased vascular reactivity due to increase in intracellular calcium levels, stimulation of the endothelium to release vasoconstrictors and loss of relaxation due to inflammation and oxidative injury of the endothelium leading to inhibition of endothelium-dependent nitric oxide production. Loss of relaxation due to inflammation and oxidative injury of the endothelium by angiotensin II leading to inhibition of endothelium-dependent nitric oxide production is the major contributors of the alcohol-induced hypertension. For the prevention of alcohol-induced hypertension is to reduce the amount of alcohol intake. Physical conditioning/exercise training is one of the most important strategies to prevent/treat chronic alcohol-induced hypertension on physiological basis. The efficacious pharmacologic treatment includes the angiotensin-converting enzyme (ACE) inhibitors or angiotensin II type 1 receptor blockers (ARBs) which have antioxidant activity and calcium channel blockers. The most effective prevention and treatment of alcohol-induced hypertension is physical exercise and the use of ACE inhibitors or ARBs in the clinic

Abstract
The influences of life habits on the cardiovascular system may have important implications for public health, as cardiovascular diseases are among the leading causes of shorter life expectancy worldwide. A link between excessive ethyl alcohol (ethanol) consumption and arterial hypertension was first suggested early last century. Since then, this proposition has received considerable attention. Support for the concept of ethanol as a cause of hypertension derives from several epidemiologic studies demonstrating that in the general population, increased blood pressure is significantly correlated with ethanol consumption. Although the link between ethanol consumption and hypertension is well established, the mechanism through which ethanol increases blood pressure remains elusive. Possible mechanisms underlying ethanol-induced hypertension were proposed based on clinical and experimental observations. These mechanisms include an increase in sympathetic nervous system activity, stimulation of the renin-angiotensin-aldosterone system, an increase of intracellular Ca2+ in vascular smooth muscle, increased oxidative stress and endothelial dysfunction. The present report reviews the relationship between ethanol intake and hypertension and highlights some mechanisms underlying this response. These issues are of interest for the public health, as ethanol consumption contributes to blood pressure elevation in the population.

Abstract
BACKGROUND Although heavy alcohol consumption is associated with hypertension, the impact of lighter consumption on blood pressure (BP) is controversial. The protective effect of light alcohol consumption on cardiovascular disease described in previous studies could be, in part, mediated by effects of alcohol on BP. However, only a few studies investigating the association between alcohol and BP included elderly subjects, despite their higher risk of hypertension sequelae. Accordingly, we evaluated the relationship between alcohol consumption and 24-hour ambulatory BP in a community-based elderly cohort. METHODS Among the participants in the Cardiac Abnormalities and Brain Lesion study, 553 subjects (mean age = 70.6 ± 9.6 years) who underwent 24-hour ambulatory BP monitoring were examined. Alcohol consumption was categorized as (i) none (reference; <1 drink/month); (ii) very light consumption (1 drink/month to 1 drink/week); (iii) light consumption (2 drinks/week to 1 drink/day); (iv) moderate-to-heavy consumption (>1 drink/day). Former drinkers were excluded. RESULTS After adjustment for relevant covariables, mean values of daytime diastolic BP (DBP), nighttime DBP, and 24-hour DBP were significantly higher in moderate-to-heavy drinkers than in the reference group, whereas systolic BP parameters were not significantly different across consumption groups. Daytime systolic BP and DBP variability (SD of the measurements) were significantly lower in very light drinkers than in the reference group, independent of potential confounders. CONCLUSIONS Moderate-to-heavy alcohol consumption was associated with higher DBP values. Very light alcohol consumption was associated with reduced daytime BP variability. The latter association may contribute to the known beneficial cardiovascular effects of light alcohol consumption.

Abstract
The objective of this study was to examine the effect of age on the relationship between alcohol consumption and incident hypertension in a general Japanese population. A cohort of Japanese men (n=37 310) and women (n=78 426) aged 40 to 79 years who underwent community-based health checkups from 1993 to 2004 and were free of hypertension were followed up with annual examinations, including the measurement of blood pressure, until the end of 2010. Incident hypertension was defined as systolic blood pressure of ≥140 mm Hg, diastolic blood pressure of ≥90 mm Hg, or the initiation of treatment for hypertension. Hazard ratios for incident hypertension according to alcohol consumption were estimated using a Cox proportional hazards model adjusted for possible confounding variables. A total of 45 428 participants (39.3%) developed hypertension (16 155 men and 29 273 women) for a mean follow-up time of 3.9 (1-18) years. Significant associations between alcohol consumption and incident hypertension were found in both sexes and age groups (P for trend was <0.001 for men aged 40-59 years and aged 60-79 years; 0.004 for women aged 40-59 years and 0.026 for women aged 60-79 years). No significant interaction with age on the association of alcohol consumption with incident hypertension was found in either sex (P for interaction, >0.05). Our results suggest that alcohol consumption is a similar risk factor for incident hypertension in both the middle-aged and the older populations.

Abstract
AIMS The aim of this consensus paper is to review the available evidence on the association between moderate alcohol use, health and disease and to provide a working document to the scientific and health professional communities. DATA SYNTHESIS In healthy adults and in the elderly, spontaneous consumption of alcoholic beverages within 30 g ethanol/d for men and 15 g/d for women is to be considered acceptable and do not deserve intervention by the primary care physician or the health professional in charge. Patients with increased risk for specific diseases, for example, women with familiar history of breast cancer, or subjects with familiar history of early cardiovascular disease, or cardiovascular patients should discuss with their physician their drinking habits. No abstainer should be advised to drink for health reasons. Alcohol use must be discouraged in specific physiological or personal situations or in selected age classes (children and adolescents, pregnant and lactating women and recovering alcoholics). Moreover, the possible interactions between alcohol and acute or chronic drug use must be discussed with the primary care physician. CONCLUSIONS The choice to consume alcohol should be based on individual considerations, taking into account the influence on health and diet, the risk of alcoholism and abuse, the effect on behaviour and other factors that may vary with age and lifestyle. Moderation in drinking and development of an associated lifestyle culture should be fostered.

Abstract
CONTEXT AND OBJECTIVE Epidemiological studies show the apparent link between excessive alcohol consumption and hypertension. However, the association between alcohol intake and blood pressure among non-hypertensive individuals is scarcely examined. METHODS This analysis included participants in the 1999-2004 National Health and Nutrition Examination Survey who were aged 20 to 84 years without a diagnosis of cardiovascular disease, hypertension or pregnancy, whose systolic/diastolic blood pressure (SBP/DBP) was lower than 140/90 mmHg, who were not on antihypertensive medication, and who consumed 12 drinks or more during the past 12 months (N = 3957). Average drinking volume (average alcohol intake per day), usual drinking quantity (drinks per day when drinking) and frequency of binge drinking were used to predict SBP/DBP. Covariates included age, gender, race/ethnicity, education level, smoking status, average physical activity level, and daily hours spent on TV/ video/computer. RESULTS Drinking volume was directly associated with higher SBP in a linear dependent manner (an increment of 10 g of alcohol per day increased average SBP by 1 mmHg among both men and women). Drinking above the US Dietary Guidelines (men more than two drinks and women more than one drink per drinking day) was associated with higher SBP. Binge drinking was associated with both higher SBP and higher DBP. Average intake greater than two drinks per day was particularly associated with higher DBP among women (P = 0.0003). CONCLUSION This analysis from a population-based survey indicates a direct association between higher alcohol consumption and a higher prevalence of prehypertension among non-hypertensive drinkers.

Abstract
Although neighbourhood social capital can be beneficial for individual health, supporting evidence in the UK is scant. We aim to find the net effect of neighbourhood social capital and deprivation on individual health beyond sociodemographic composition of neighbourhood. We propose a multilevel path analytic model of health to delineate complex pathways involving neighbourhoods (measured as local super output area) and individuals. Analysis of the most recent data containing independent measures of neighbourhood social capital shows that neighbourhood social capital appears to be associated with benefits in some aspects of individual health in the Welsh setting. The improvement stands beyond individual determinants and neighbourhood deprivation. Social scientists and public health officials have reason to continue focusing on the neighbourhoods as well as the individuals to improve the health of the population.

Abstract
PURPOSE The pressor effect of caffeine has been established in young men and premenopausal women. The effect of caffeine on blood pressure (BP) remains unknown in postmenopausal women and in relation to hormone replacement therapy (HRT) use. MATERIALS AND METHODS In a randomized, 2-week cross-over design, we studied 165 healthy men and women in 6 groups: men and premenopausal women (35-49 yrs) vs. men and postmenopausal women (50-64 yrs), with postmenopausal women divided into those taking no hormone replacements (HR), estrogen alone, or estrogen and progesterone. Testing during one week of the study involved 6 days of caffeine maintenance at home (80 mg, 3x/day) followed by testing of responses to a challenge dose of caffeine (250 mg) in the laboratory. The other week involved ingesting placebos on maintenance and lab days. Resting BP responses to caffeine were measured at baseline and at 45 to 60 min following caffeine vs placebo ingestion, using automated monitors. RESULTS Ingestion of caffeine resulted in a significant increase in systolic BP in all 6 groups (4 +/- .6, p < 0.01). Diastolic BP significantly increased in response to caffeine in all (3 +/- .4, p < 0.04) but the group of older men (2 +/- 1.0, p = 0.1). The observed pressor responses to caffeine did not vary by age. CONCLUSIONS Caffeine resulted in an increase in BP in healthy, normotensive, young and older men and women. This finding warrants the consideration of caffeine in the lifestyle interventions recommended for BP control across the age span.

Abstract
INTRODUCTION AND AIMS This study aims to examine the causal effect of alcohol consumption on the risk of high blood pressure in Russia. DESIGN AND METHODS Using data from the Russian Longitudinal Monitoring Survey, we estimated the influence of alcohol consumption on high blood pressure, controlling for social and other factors related to alcohol use. To address the issue of causality, we instrumented alcohol consumption by the number of frequent alcohol drinkers in the household. RESULTS We found that frequent consumption of vodka and beer has an adverse impact on health. In particular, frequent vodka consumption increases the likelihood of high blood pressure by 2.88% while frequent beer consumption increases it by 2.06%. Controlling for the endogeneity of frequent alcohol consumption using the instrumental variable method produces an even larger effect for frequent vodka consumption, with a marginal effect of 7.23%. DISCUSSION AND CONCLUSION Prevention policies as well as government programs aimed at treating alcohol-related health outcomes should take into consideration the significant adverse effect of alcohol consumption on high blood pressure. It is also recommended that policy interventions aimed to address alcohol addiction issues in Russia explicitly differentiate between vodka and beer drinkers.

Abstract
AIMS Excessive alcohol use in the form of binge drinking is associated with many adverse medical outcomes. Using an animal model, the primary objective of this study was to determine the effects of repeated episodes of binge drinking on myocardial structure, blood pressure (BP) and activation of mitogen-activated protein kinases (MAPKs). The effects of carvedilol, a beta-adrenergic blocker, were also examined in this animal model of binge drinking. METHODS Rats were randomized into three groups: control, binge and binge + carvedilol (20 mg/kg). Animals received intragastric administration of 5 g ethanol/kg in the morning × 4 days (Monday-Thursday) followed by no ethanol on Friday-Sunday. Animals were maintained on the protocol for 5 weeks. BP was measured using radiotelemetry methods. Animals underwent echocardiography at baseline, 2.5 and 5 weeks. Myocardial MAPKs were analyzed at 5 weeks using western blot techniques. RESULTS Over the course of 5 weeks, binge drinking was associated with significant transient increases in BP that were greater at 4 and 5 weeks compared with earlier time points. Carvedilol treatment significantly attenuated the binge-induced transient increases in BP at 4 and 5 weeks. No significant changes were found in echocardiographic parameters at any time period; however, binge drinking was associated with increased phosphorylation of p38 MAPK, which was blocked by carvedilol treatment. CONCLUSION Repeated episodes of binge drinking result in progressive and transient increases in BP, no change in myocardial structure and differential regulation of MAPK activation.

Abstract
There is increasing evidence for a protective effect of tea consumption against cardiovascular disease. This review summarizes the available epidemiological data providing evidence for and against such an effect. We also review observational and intervention studies that investigated an effect of tea and tea extracts on cardiovascular risk factors, including blood pressure, serum lipids, diabetes mellitus, and obesity. Finally, we review potential mechanisms of benefit, including anti-inflammatory, anti-oxidant, and anti-proliferative effects, as well as favorable effects on endothelial function. Overall, the observational data suggest a benefit, but results are mixed and likely confounded by lifestyle and background dietary factors. The weight of evidence indicates favorable effects on risk factors and a number of plausible mechanisms have been elucidated in experimental and translational human studies. Despite the growing body evidence, it remains uncertain whether tea consumption should be recommended to the general population or to patients as a strategy to reduce cardiovascular risk.

Abstract
BACKGROUND It has been suggested that in animal models, red wine may have a protective effect on the vascular endothelium. However, it is not known whether this effect is also present in human small vessels and whether it is specific for certain wines. The objective of this study is to compare the vasodilator effects in subcutaneous small resistance arteries of wines with different flavonoid content as well as of ethanol vs. wines in normotensive (NT) subjects and in patients with essential hypertension (EH). METHODS Twenty-six EH and 27 NT were included in the study. Subcutaneous small resistance arteries were dissected and mounted on a micromyograph. Then we evaluated vasodilator responses as concentration-response curves (20, 30, and 50 microl) to the following items: (i) a red wine produced in small oak barrels ("en barrique": EB) (Barolo Oberto 1994), (ii) a red wine produced in large wood barrels (LB) (Barolo Scarzello 1989), (iii) a red wine produced in steel tanks (Albarello Rosso del Salento 1997), and (iv) a white wine produced in steel tanks in the presence or absence of an inhibitor of the nitric oxide (NO) synthase (L-NMMA 100 micromol/l). RESULTS A dose-dependent vasodilator effect of red wines (particularly EB and LB) was detected in both NT and HT. The observed response was not reduced after preincubation with L-NMMA. CONCLUSIONS Our results suggest red wines are more potent vasodilator than ethanol alone, possibly depending on the content of polyphenols or tannic acid. HT show similar responses compared with NT, indicating that red wine is not harmful in this population.

Abstract
The relation between alcohol consumption and incident hypertension is unclear, and most observational studies have not accounted for socioeconomic factors. This study examined the association between alcohol consumption in a diverse group of young adults and incident hypertension over 20 years. Participants (n = 4,711) were from the Coronary Artery Risk Development in Young Adults Study cohort, recruited in 1985 (aged 18-30 years) from Birmingham, Alabama; Chicago, Illinois; Minneapolis, Minnesota; and Oakland, California. The 20-year incidence of hypertension for never, former, light, moderate, and at-risk drinkers was 25.1%, 31.8%, 20.9%, 22.2%, and 18.8%, respectively (P < 0.001). Race, gender, age, family history of hypertension, body mass index, income, education, and difficulty paying for basics and medical care were associated with hypertension. Adjustment using Cox proportional hazard models revealed no association between baseline alcohol consumption and incident hypertension, except among European-American women in whom any current alcohol consumption was associated with lower risk of incident hypertension. The lack of association between alcohol and hypertension in the majority of this socioeconomically diverse cohort is not definitive. Future studies should include social factors, such as income and education, and consider additional characteristics that may modify or confound associations between alcohol and blood pressure.

Abstract
The substantial medical risks of heavy alcohol drinking as well as the probable existence of a less harmful or safe drinking limit have been evident for centuries. Modern epidemiology studies suggest lowered risk of morbidity and mortality among lighter drinkers. Thus, defining "heavy" drinking as > or =3 standard drinks per day, the alcohol-mortality relationship is a J-curve with risk highest for heavy drinkers, lowest for light drinkers and intermediate for abstainers. A number of non-cardiovascular and cardiovascular problems contribute to the increased mortality risk of heavier drinkers. The lower risk of light drinkers is due mostly to lower risk of the most common cardiovascular condition, coronary heart disease (CHD). These disparate relationships of alcoholic drinking to various cardiovascular and non-cardiovascular conditions constitute a modern concept of alcohol and health. Increased cardiovascular risks of heavy drinking include: (1) alcoholic cardiomyopathy, (2) systemic hypertension (high blood pressure), (3) heart rhythm disturbances, and (4) hemorrhagic stroke. Lighter drinking is not clearly related to increased risk of any cardiovascular condition and, in observational studies, is related to lower risk of CHD, ischemic stroke, and diabetes mellitus. A protective hypothesis for CHD is supported by evidence for plausible biological mechanisms attributable to ethyl alcohol. International comparisons and some prospective study data suggest that wine is more protective against CHD than liquor or beer. Possible non-alcohol beneficial components in wine (especially red) support possible extra protection by wine, but a healthier pattern of drinking or more favorable risk traits in wine drinkers may be involved.

Abstract
BACKGROUND Alcohol intake and smoking have been reported to influence atherosclerotic progression. OBJECTIVE The purpose of this study was to determine whether the associations of alcohol intake with blood pressure (BP) and serum lipid concentrations are modified by smoking in Japanese women. METHODS Eligible subjects were healthy female Japanese workers aged 35 to <55 years who had received periodic health examinations at workplaces in Yamagata Prefecture in Japan. Subjects were classified as smokers or nonsmokers and subclassified into 3 subgroups based on average daily reported alcohol intake: nondrinkers, light drinkers (<15 g/d), and heavy drinkers (>-15 g/d). The means of each variable (systolic and diastolic BP [SBP and DBP, respectively] and serum concentrations of total cholesterol [TC], low-density lipoprotein cholesterol [LDL-C], high-density lipoprotein cholesterol [HDL-C], and triglycerides) were compared among the 2 groups of smoking history and 3 subgroups of alcohol intake after adjusting for age and body mass index. RESULTS A total of 16,805 healthy women were enrolled (14,695 nonsmokers, 2110 smokers). In smokers, SBP was significantly higher in heavy drinkers than in nondrinkers, and DBP was significantly higher in light drinkers and heavy drinkers than in nondrinkers (all, P < 0.01). In nonsmokers, SBP was not significantly higher in light drinkers and heavy drinkers versus nondrinkers, and the difference in DBP between heavy drinkers and nondrinkers was significant (P < 0.01), but that between light drinkers and nondrinkers was not. In smokers but not in nonsmokers, serum TC concentration was significantly lower in heavy drinkers than in nondrinkers. In smokers and nonsmokers, LDL-C was significantly lower in light and heavy drinkers than in nondrinkers (all, P < 0.01), and serum HDL-C was significantly higher in light and heavy drinkers than in nondrinkers (all, P < 0.01). The differences in mean LDL-C between light and heavy drinkers versus nondrinkers were numerically greater in smokers than in nonsmokers. CONCLUSION In this sample of women in Japan, serum LDL-C concentration was significantly lower in drinkers than in nondrinkers, and smoking might increase this association between alcohol intake and lowered LDL-C.

Abstract
Alcohol abuse is a major predictor of premature death, and also an independent risk factor for coronary death. Alcoholics are often heavy smokers. In a large primary prevention trial in middle-aged men with 7,495 participants, registration data were used to identify subjects with alcohol problems. Smokers had slightly lower blood pressure and were somewhat leaner than non-smokers, but had slightly higher serum cholesterol levels. Alcohol-registered subjects also tended to have lower blood pressure levels, and higher serum cholesterol. The relative risk of non-fatal myocardial infarction during the follow-up period of 11.8 years was essentially doubled in smokers compared to non-smokers, regardless of registration for alcohol problems. Among the non-alcoholic subjects, the relative risk of coronary death in smokers was double that of non-smokers, whereas the risk in non-smoking alcoholic subjects was not significantly increased. In smoking alcoholics the relative risk was substantially raised to 4.2 (3.0-7.0; 95% c.i.). In multivariate analysis both smoking and alcohol abuse were independently associated with coronary death. A possible mechanism might be through a combination of tobacco-induced coronary arteriosclerosis and the cardiotoxic effects of alcohol. As to total mortality, a smoking non-alcoholic man had a relative risk of dying almost double that of a non-alcoholic non-smoker. Among non-smoking alcoholics the risk was three times and, in smoking alcoholics over four times that of the non-alcoholic non-smokers.

Abstract
This paper summarizes the current epidemiological evidence on coffee consumption in relation to blood pressure (BP) and risk of hypertension. Data from cross-sectional studies suggest an inverse linear or U-shaped association of habitual coffee use with BP in different populations. Prospective studies suggest a protective effect of high coffee intake (4 or more cups per day) against hypertension, mainly in women. Furthermore, the risk of hypertension may be lower in coffee abstainers. Randomized controlled trials, which are mostly of short duration (1–12 weeks), have shown that coffee intake around 5 cups per day causes a small elevation in BP (∼2/1 mmHg) when compared to abstinence or use of decaffeinated coffee. With regard to underlying biological mechanisms, most research has been devoted to BP-raising effects of caffeine. However, there are many other substances in coffee, such as polyphenols, soluble fibre and potassium, which could exert a beneficial effect in the cardiovascular system. Although the precise nature of the relation between coffee and BP is still unclear, most evidence suggests that regular intake of caffeinated coffee does not increase the risk of hypertension.

Abstract
Many in vivo trials have evaluated the effects of grape products on different CVD risk factors. Most published studies have dealt with some specific aspects of mechanisms of grape flavonoid action or have focused only on one product, such as wine. The aim of the present paper is to review trials dealing with grape products and CVD published during the last 13 years (seventy-five trials). Polyphenols, alcohol and dietary fibre are the main constituents of the tested products. In animal and human studies, grape products have been shown to produce hypotensive, hypolipidaemic and anti-atherosclerotic effects, and also to improve antioxidant status as measured in terms of plasma antioxidant capacity, oxidation biomarkers, antioxidant compounds or antioxidant enzymes. Differences in the design of the studies and in the composition of the tested products (not always provided) could explain the different results of these studies.

Abstract
Gender-related impact of alcohol consumption on blood pressure (BP), serum lipoprotein profile, and C-reactive protein (CRP) concentrations was evaluated prospectively. Alcohol drinking status was assessed as abstainers and categories of light, moderate, and heavy (daily >40 ml ethanol) intake. Mean age of the 3,443 men and women who were followed up for a mean of 7.4 years was 47.6+/-12 years. In each multivariable linear or logistic regression analysis, alcohol drinking status was adjusted for age, sex, smoking status, and physical activity. Among men, drinking was significantly associated positively with low-density lipo protein (LDL) cholesterol, apolipoprotein (apo) B, systolic and diastolic BP, and with CRP in a log-linear manner exhibiting features of a threshold at heavy drinking. With respect to response of serum triglycerides to light-to-moderate drinking, whereas men exhibited a significant increase, women exhibited a decline (P<.05). Lower BPs (P<.03) and CRP levels (P=.032) were observed in female drinkers than abstainers and, as distinct from men, no increases in LDL cholesterol and apoB were noted. Heavy drinking tended to protect the sexes against the risk of developing low high-density lipoprotein cholesterol levels in prospective multi adjusted analyses. Sex modulates response of cardiometabolic risk variables to moderate alcohol consumption among Turks. Only women respond with lower triglycerides and CRP, whereas men show a log-linear positive association of drinking categories with BP, LDL cholesterol, apoB, and CRP.

Abstract
Alcohol-induced endothelial changes might contribute to an increase in blood pressure in regular alcohol consumers. Some antihypertensive drugs affect oxidative stress and endothelial function and might counteract the effects of alcohol at the cellular level. The aim of this study was to investigate in vitro the effects of three different types of antihypertensive agents on alcohol-induced endothelial responses and oxidative stress. Cultured human endothelial cells were exposed to increasing concentrations (1, 10, 60 micromol/L) of zofenoprilat, carvedilol, and lacidipine in the absence and in the presence of ethanol (140 mmol/L). Concentrations of endothelin (ET) and nitric oxide (NO) were measured in the culture media as markers of endothelial function, and malondialdehyde (MDA) and intracellular glutathione (GSHi) were measured as markers of oxidative stress. Exposure to alcohol increased the levels of ET, NO, and MDA, and decreased GSHi. Carvedilol and zofenoprilat were more effective than lacidipine in counteracting the effects of alcohol on ET production. Alcohol-induced NO production was enhanced by carvedilol, whereas zofenoprilat and lacidipine did not have a significant effect. The alcohol-induced increase in MDA concentrations was blunted by all three drugs, but only carvedilol restored a normal response. All three drugs increased GSHi levels, with the effect being greater for carvedilol and lacidipine than zofenoprilat. Carvedilol is more effective than zofenoprilat and lacidipine in counteracting alcohol-induced endothelial responses in vitro and in decreasing oxidative stress. These effects might be particularly beneficial in patients with alcohol-related hypertension.

Abstract
In order to determine the threshold amount of alcohol consumption for blood pressure, we calculated the benchmark dose (BMD) of alcohol consumption and its 95% lower confidence interval (BMDL) in Japanese workers. The subjects consisted of 4,383 males and 387 females in a Japanese steel company. The target variables were systolic, diastolic, and mean arterial pressures. The effects of other potential covariates such as age and body mass index were adjusted by including these covariates in the multiple linear regression models. In male workers, BMD/BMDL for alcohol consumption (g/week) at which the probability of an adverse response was estimated to increase by 5% relative to no alcohol consumption, were 396/315 (systolic blood pressure), 321/265 (diastolic blood pressure), and 326/269 (mean arterial pressures). These values were based on significant regression coefficients of alcohol consumption. In female workers, BMD/BMDL for alcohol consumption based on insignificant regression coefficients were 693/134 (systolic blood pressure), 199/90 (diastolic blood pressure), and 267/77 (mean arterial pressure). Therefore, BMDs/BMDLs in males were more informative than those in females as there was no significant relationship between alcohol and blood pressure in females. The threshold amount of alcohol consumption determined in this study provides valuable information for preventing alcohol-induced hypertension.

Abstract
BACKGROUND AND PURPOSE Epidemiological data suggest that the risk of ethanol-associated cardiovascular disease is greater in men than in women. This study investigates the mechanisms underlying gender-specific vascular effects elicited by chronic ethanol consumption in rats. EXPERIMENTAL APPROACH Vascular reactivity experiments using standard muscle bath procedures were performed on isolated thoracic aortae from rats. mRNA and protein for inducible NO synthase (iNOS) and for endothelial NOS (eNOS) was assessed by RT-PCR or western blotting, respectively. KEY RESULTS In male rats, chronic ethanol consumption enhanced phenylephrine-induced contraction in both endothelium-intact and denuded aortic rings. However, in female rats, chronic ethanol consumption enhanced phenylephrine-induced contraction only in endothelium denuded aortic rings. After pre-incubation of endothelium-intact rings with L-NAME, both male and female ethanol-treated rats showed larger phenylephrine-induced contractions in aortic rings, compared to the control group. Acetylcholine-induced relaxation was not affected by ethanol consumption. The effects of ethanol on responses to phenylephrine were similar in ovariectomized (OVX) and intact (non-OVX) female rats. In the presence of aminoguanidine, but not 7-nitroindazole, the contractions to phenylephrine in rings from ethanol-treated female rats were greater than that found in control tissues in the presence of the inhibitors. mRNA levels for eNOS and iNOS were not altered by ethanol consumption. Ethanol intake reduced eNOS protein levels and increased iNOS protein levels in aorta from female rats. CONCLUSIONS AND IMPLICATIONS Gender differences in the vascular effects elicited by chronic ethanol consumption were not related to ovarian hormones but seemed to involve the upregulation of iNOS.

Abstract
BACKGROUND Wide pulse pressure is a potent risk factor for atherosclerotic disease, and hypertension is induced by habitual alcohol drinking. This concise study investigated whether age affects the relationship between alcohol drinking and pulse pressure. METHODS The participants were 99 661 male workers (20-69 years old) who had received periodic health check-ups. The mean levels of pulse pressure and blood pressure were compared among three different groups divided by the average amount of daily alcohol intake (nondrinkers; light drinkers, < 30 g ethanol/day; heavy drinkers, >or= 30 g ethanol/day) in each age group. RESULTS The mean pulse pressure was decreased in the thirties and forties age groups compared with that in the twenties age group, and then was increased with advance of age in the fifties and sixties age groups. Pulse pressure was significantly wider in heavy drinkers than in nondrinkers and light drinkers in all age groups, and the difference between pulse pressure of nondrinkers and that of heavy drinkers was greater in the fifties and sixties age groups than in the younger groups. Pulse pressure in light drinkers was significantly wider than that in nondrinkers in the fifties and sixties age groups but was not different from that in nondrinkers in the twenties to forties age groups. CONCLUSIONS Association of alcohol intake with pulse pressure is dependent on the amount of alcohol and is stronger in the elderly. Age as well as amount of alcohol intake should therefore be taken into account when the influence of alcohol drinking on pulse pressure is considered.
