The hypothesis that the action of alcohol on blood pressure is rapidly reversible and that its effect is therefore mainly due to very recent alcohol consumption was examined in this study. Five hundred and seventy-seven subjects were screened in an occupational survey. Alcohol consumption, documented with a 1-week retrospective diary was divided into two categories: "recent" and "previous" intake. Recent intake was defined as the amount consumed on days 1, 2, and 3 immediately preceding blood pressure measurement. Previous intake was defined as the amount consumed on days 4, 5, and 6 preceding blood pressure measurement. High recent alcohol intake significantly raised systolic and diastolic blood pressure in both men and women. Previous alcohol intake, however, did not appear to influence blood pressure. We conclude that the effect of alcohol on blood pressure appears to be predominantly due to alcohol consumed in the few days immediately preceding blood pressure measurement, with alcohol consumption before those few days exerting little effect on blood pressure.

Out of 1800 men and 1800 women being the random sample of population of two Warsaw districts aged 35-64 years, 1309 men and 1337 women (response rate 72.7% and 74.3% were screened in 1984 within the framework of the Pol-MONICA Warsaw Project. Standardized mean values of systolic blood pressure did not differ between men and women but the mean values of diastolic blood pressure were higher in men. Mean values of systolic and diastolic blood pressure increased in both sexes with age, however diastolic blood pressure increased only up to age 45-54 years. Prevalence of hypertension according to WHO criteria was higher in men than in women and in both sexes increased with age. Among subjects with hypertension the mild diastolic hypertension was most frequent. The high percentage of subjects with hypertension at screening was not previously detected (47.4% men and 27.6% women). The fact of hypertension detection was not equal with undertaking therapy because 58.9% men and 46.6% women with detected hypertension were never treated. The effectiveness of therapy (achieving goal) was 24% in men and 27.4% in women. The performed multiple regression analysis indicated that Quetelet index and pulse rate were independently related with systolic blood pressure in both sexes and additionally education level, alcohol consumption and HDL-cholesterol concentration in men and age and family history of hypertension in women. As far as the diastolic blood pressure is concerned the Quetelet index, pulse rate and family history were significantly related in both sexes and additionally in men ethanol consumption and HDL-cholesterol concentration.

Alcoholism is a prevalent problem of contemporary society, yet there are virtually no clinically effective drugs for the management of this disorder. A previous study demonstrating the ability of angiotensin-converting enzyme (ACE) inhibitors to attenuate voluntary alcohol intake in rats prompted the suggestion that these drugs, currently marketed for the treatment of hypertension, may also be useful in dealing with human alcohol abuse. The present experiments explored in more detail the effect and possible mechanisms of action of this class of drug on alcohol consumption in rats. Experiment one demonstrated that Abutapril, a new ACE inhibitor, significantly reduced alcohol intake and that this effect could not be blocked by either an ANG II or an opiate receptor antagonist suggesting that neither the peripheral renin-angiotensin system (RAS) nor the endogenous enkephalins are involved in the ability of ACE inhibition to attenuate alcohol intake. Experiments two and three showed that ACE inhibition effectively reduced alcohol drinking faster in animals with elevated RAS activity and not at all in animals with suppressed RAS activity indicating that initial levels of RAS activity may determine the speed and ability of ACE inhibition to attenuate alcohol intake. ACE inhibitors may reduce alcohol intake by elevating a nonapeptide fragment or by elevating central ANG II levels. The assessment of this class of drugs to reduce alcohol intake in humans should include a monitoring of the initial level of activity in the renin-angiotensin system since this may be a predictor of the effectiveness of treatment with the ACE inhibitors.

After smoking "crack" cocaine and consuming large quantities of ethanol, a 36-year-old man developed multiple, bilateral, deep, and superficial cerebral hematomas. He was hypertensive for several days, but angiography revealed no evidence of vascular malformation or vasculitis. The multifocality of the hematomas and lack of underlying disease suggest that the hemorrhages resulted from cocaine-induced acute hypertension or arterial spasm, possibly potentiated by heavy ethanol consumption.

Ethanol in acute low doses is believed to be relatively nontoxic to the normal myocardium, despite data indicating low-level contractility impairment. In patients with myocardial disease, or as the serum ethanol concentration is increased to high levels, angina, myocardial infarction, and arrhythmia may be potentiated. Chronic ethanol use, at moderate doses, may be protective against coronary artery disease, despite increased rates of hypertension. Alcohol consumption at high doses may result in dilated cardiomyopathy and a dismal prognosis. Alcohol abuse is associated with increased mortality.

The relations of systolic and diastolic blood pressures to alcohol intake and exercise tolerance levels in 15,612 men and 3,855 women were investigated. Alcohol intake was assessed by questionnaire and stratified into seven levels for men and six for women according to the ounces of ethanol consumed per week. Exercise tolerance was determined by maximal treadmill exercise testing and was categorized into six age-specific by sex-specific levels. Both systolic and diastolic blood pressure were significantly related to both alcohol intake and exercise tolerance levels in both men and women. These relations, which were positive for alcohol and negative for exercise tolerance, remained after covariance adjustment for age, body mass index, and cigarette smoking. Alcohol intake was not significantly correlated with exercise tolerance. The relation of blood pressure to alcohol was not linear because the blood pressure of moderate consumers of alcohol tended to be slightly lower than that of nondrinkers. Higher blood pressure was found only in drinkers whose ethanol intake exceeded 9.5 ounces (approximately 285 ml or 19 drinks) per week. However, heavy drinkers in high exercise tolerance categories had no higher blood pressure than nondrinkers in low exercise tolerance groups. Exercise tolerance or physiological fitness appears to be important in quantifying the relation between alcohol intake and blood pressure and should be considered in describing this relation.

We examined the prevalence of high ethanol intake, hypertension, and other risk factors for intracerebral hemorrhage in a case-control study of 24 young and middle-aged patients with intracerebral hemorrhage. We recorded ethanol consumption, history of hypertension, liver disease, cigarette smoking, and mild or severe coagulation disorder in each case of intracerebral hemorrhage and in 48 control patients matched by sex and age. In univariate matched analyses, the frequencies of high ethanol intake (p = 0.009), hypertension (p = 0.05), and coagulation disorder (p = 0.05) were higher in the cases than in the controls. After controlling for possible confounding factors, we found that high ethanol intake and hypertension were the only independent risk factors for intracerebral hemorrhage (p = 0.02 and p = 0.05, respectively). The hemorrhagic lesion found in cases with a high ethanol intake tended to be located in the cerebral lobes (p = 0.01), contrasting with the typical basal ganglia location of hypertensive hematomas (p = 0.009). We conclude that chronic, high ethanol intake should be considered as an important risk factor for lobar hematomas in young and middle-aged people.

Screening in general practice revealed a total of 124 patients (71 men and 53 women) with severe hypercholesterolaemia, defined as serum cholesterol levels over the 95th percentile for sex and age. The average serum cholesterol was 9.3 mmol/l with a maximal value of 15.5 mmol/l. On the basis of a dietary history for 48 hours and a dietetic interview, a dietician undertook a dietary analysis with the help of a computer programme (DANKOST) before and after dietary alterations for one and three months. The aims were normal body weight, cholesterol intake of under 200 mg/day, ratio between saturated and unsaturated fat between 1.0 and 1.8 and a roughage content of 26-30 g/day. A total of 61 patients completed the recommended dietary alterations. Alcohol intake was significantly higher in men and constituted more than 8% of the energy intake in 43 patients. Serum cholesterol was reduced by a total of 15.3%, triglyceride by nearly 20% while high density lipoprotein remained unchanged. The maximal decrease in serum cholesterol was 43%. In patients who adhered to the dietary changes, the average decrease was over 20%. Patients with hypertension and patients with serum cholesterol levels greater than or equal to 9 mmol/l showed greater decreases than the group as a whole. On the basis of the dietary interview, it did not prove possible to predict which patients would stick to the dietary restrictions.

We compared the cross-sectional association of alcohol consumption with blood pressure in 810 Japanese men (JM) living in Tokyo and 946 white men (WM) living in New York. Mean systolic (JM and WM, p less than 0.001) and diastolic blood pressure (JM, p less than 0.002; WM, p less than 0.001) were associated with alcohol consumption in both groups. Compared to abstainers, the heaviest drinkers had the highest systolic (JM, p = 0.001; WM, p less than 0.01) and diastolic (JM, p less than 0.002; WM, p less than 0.05) blood pressures. The relation of blood pressure to alcohol intake was J-shaped in the Americans, but linear in the Japanese. Exploratory analyses revealed that the J-shape may have been due to under-reporting of heavy alcohol ingestion by American abstainers. When abstainers were excluded, the relationships were similar in both the American and Japanese. The positive association between blood pressure and alcohol consumption persisted after adjustment for age, cigarette smoking, use of antihypertensive medications, body mass index, heart rate, abdominal skinfold thickness, hematocrit, fasting blood glucose, serum uric acid levels and urinary sodium/potassium ratio. Alcohol use was also related to prevalence of hypertension. These findings confirm the presence of an independent association between alcohol intake and blood pressure in both JM and WM and suggest that, despite differences in the metabolism of alcohol, the relation of alcohol consumption to blood pressure is similar in both nationalities.

Research on the interaction of alcohol and stress on the cardiovascular system published since 1981 is reviewed. Important variables that can modify the interaction of alcohol and stress are also discussed. Consistent findings have come from studies on stress-induced tachycardia which has been shown to be decreased by alcohol ingestion. Evidence from clinical, cohort, case-control, epidemiological research indicates that long-term ingestion of alcohol is associated with lower risk of coronary heart disease. Less clear is the association of the risk of hypertension and alcohol ingestion. Primarily in women, there might be a threshold low level of alcohol consumption which is not associated with the development of hypertension. With some stressors, alcohol may depress the stressor-induced elevation of plasma catecholamines. Mechanisms believed to mediate the described alcohol-stress interaction are discussed. Existing evidence support the following mechanisms: mediation via changes in plasma lipoproteins in the case of coronary heart disease and changes in plasma calcium levels for the blood pressure effects.
