Abstract
Alcohol is the most frequently consumed toxic substance in the world and remains a major global public health issue, with one in three adults consuming it worldwide. Alcohol use is a leading risk factor for disease, contributing to over 60 acute and chronic health conditions, with a particularly complex association with cardiovascular disease. Chronic excessive alcohol consumption is associated with a range of cardiac complications, including decreased myocardial contractility, hypertension, arrhythmias, MI and heart failure. However, low-level alcohol consumption is believed to have a protective effect against ischaemic heart disease and diabetes. In most cohort studies, small to moderate amounts of alcohol consumption have not been linked to heart failure, indicating a threshold effect of alcohol with individual (possibly genetic) predisposition rather than a continuous effect of exposure. This review article explores the potential benefits of alcohol on the heart, the association between alcohol use and alcoholic cardiomyopathy and the epidemiology, clinical correlates and management of alcoholic cardiomyopathy.

Abstract
BACKGROUND We analyzed the association between light-to-moderate alcohol intake and the risk of heart failure (HF). METHODS AND RESULTS We studied 60,665 individuals free of HF who provided information on alcohol consumption in a population-based cohort study conducted in 1995-97 in Norway. Sociodemographic factors, cardiovascular risk factors and common chronic disorders were assessed by questionnaires and/or by a clinical examination. The cohort was followed for a first HF event for an average of 11.2 ± 3.0 years. Mean alcohol consumption was 2.95 ± 4.5 g/day; 1588 HF cases occurred during follow-up. The quantity of alcohol consumption was inversely associated with incident HF in this low-drinking population. The risk was lowest for consumption over three but less than six drinks/week; the multivariate hazard ratio when comparing this category to non-drinkers was 0.67 (95% CI: 0.50-0.92). Among problem drinkers based on CAGE questionnaires, total consumption showed no favorable association with HF, even when overall consumption was otherwise moderate. Excluding former drinkers and controlling for common chronic diseases had minimal effect on these associations. Frequent alcohol consumption, i.e. more than five times/month, was associated with the lowest HF risk; the adjusted hazard ratio comparing this group to alcohol intake less than once/month was 0.83 (95% CI: 0.68-1.03). We found no evidence for a differential effect according to beverage type, nor that the competing risks of death from other causes modified the association. CONCLUSIONS Frequent light-to-moderate alcohol consumption without problem drinking was associated with a lower HF risk in this population characterized by a low average alcohol intake.

Abstract
Alcohol is the most frequently consumed toxic substance in the world. Low to moderate daily intake of alcohol has been shown to have beneficial effects on the cardiovascular system. In contrast, exposure to high levels of alcohol for a long period could lead to progressive cardiac dysfunction and heart failure. Cardiac dysfunction associated with chronic and excessive alcohol intake is a specific cardiac disease known as alcoholic cardiomyopathy (ACM). In spite of its clinical importance, data on ACM and how alcohol damages the heart are limited. In this review, we evaluate available evidence linking excessive alcohol consumption with heart failure and dilated cardiomyopathy. Additionally, we discuss the clinical presentation, prognosis and treatment of ACM.

Abstract
Numerous studies have used a J-shaped or U-shaped curve to describe the relationship between alcohol use and total mortality. The nadir of the curves based on recent meta-analysis suggested optimal benefit at approximately half a drink per day. Fewer than 4 drinks per day in men and fewer than 2 per day in women appeared to confer benefit. Reductions in cardiovascular death and nonfatal myocardial infarction were also associated with light to moderate alcohol intake. Although some studies suggested that wine had an advantage over other types of alcoholic beverages, other studies suggested that the type of drink was not important. Heavy drinking was associated with an increase in mortality, hypertension, alcoholic cardiomyopathy, cancer, and cerebrovascular events, including cerebrovascular hemorrhage. Paradoxically, light-to-moderate alcohol use actually reduced the development of heart failure and did not appear to exacerbate it in most patients who had underlying heart failure. Numerous mechanisms have been proposed to explain the benefit that light-to-moderate alcohol intake has on the heart, including an increase of high-density lipoprotein cholesterol, reduction in plasma viscosity and fibrinogen concentration, increase in fibrinolysis, decrease in platelet aggregation, improvement in endothelial function, reduction of inflammation, and promotion of antioxidant effects. Controversy exists on whether alcohol has a direct cardioprotective effect on ischemic myocardium. Studies from our laboratory do not support the concept that alcohol has a direct cardioprotective effect on ischemic/reperfused myocardium. Perhaps the time has come for a prospectively randomized trial to determine whether 1 drink per day (or perhaps 1 drink every other day) reduces mortality and major cardiovascular events.

Abstract
Moderate drinking has complex associations with cardiovascular diseases other than coronary heart disease. Recent cohort studies examining the relationship between alcohol use and ischemic stroke have shown a modest association, with risk ratios approximating 0.8 and the lowest risk among those who drink less than daily. In contrast, alcohol use is generally associated with an approximate dose-dependent risk for hemorrhagic stroke throughout the full range of intake. Several prospective studies of alcohol intake and congestive heart failure have found lower risk with moderate drinking. This risk is also dose dependent through the moderate range, but its underlying mechanism remains uncertain. Accounting for the lower risk of myocardial infarction associated with moderate intake does not eliminate the observed association. Cohort studies have found no association of long-term alcohol intake with risk of atrial fibrillation below levels of at least 3 standard drinks per day. Finally, two prospective studies have found lower risks of claudication or clinically more severe peripheral arterial disease among moderate drinkers, an association also supported by cross-sectional studies of alcohol intake and ankle-brachial index.

Abstract
OBJECTIVES We investigated the association between alcohol consumption and incident congestive heart failure (CHF) both overall and after adjusting for incident myocardial infarction (MI). BACKGROUND Moderate alcohol consumption has been associated with lower risk of CHF and MI. METHODS The Cardiovascular Health study, a prospective cohort study of cardiovascular disease risk factors and outcomes, followed 5,888 subjects > or =65 years old for 7 to 10 years. Cox models were used to estimate the adjusted risk of CHF by reported alcohol consumption. RESULTS There were 5,595 subjects at baseline at risk for incident CHF with alcohol data and 1,056 events during follow-up. Compared with abstainers, the adjusted risk of CHF was lower among subjects who reported consuming 1 to 6 drinks per week (hazard ratio [HR] 0.82, 95% confidence interval [CI] 0.67 to 1.00, p = 0.05) and 7 to 13 drinks per week (HR 0.66, 95% CI 0.47 to 0.91, p = 0.01). Time-dependent adjustment for incident MI altered only slightly the association between moderate alcohol consumption and CHF (for 1 to 6 drinks per week, HR 0.84, 95% CI 0.65 to 1.04; for 7 to 13 drinks per week, HR 0.69, 95% CI 0.49 to 0.99). Baseline former drinkers had a higher risk of CHF than abstainers (HR 1.51, p < 0.01), but those who quit during the study did not have a higher risk (HR 0.83, 95% CI 0.66 to 1.03). CONCLUSIONS Moderate alcohol use is associated with a lower risk of incident CHF among older adults, even after accounting for incident MI and other factors.

Abstract
Substantial evidence has shown that moderate drinkers have lower rates of coronary heart disease (CHD) than abstainers, but the effects of alcohol consumption among patients with established CHD are less clear. Alcohol intake has important effects on risk factors for reinfarction, including higher levels of high-density lipoprotein cholesterol and triglycerides, lower levels of fibrinogen and other prothrombotic factors, lower fibrinolytic potential, and antiplatelet activity. Studies of patients at risk for CHD, such as those with diabetes, hypertension, and hyperlipidemia, have shown that the association of moderate drinking and CHD is at least as strong as it is in the general population. Most recently, studies have found that survivors of acute myocardial infarction who drink moderately have a risk of death approximately 20%-30% lower than do abstainers or rare drinkers. Nonetheless, the risks and benefits of alcohol use remain complex, even among patients with CHD, and no simple recommendation regarding alcohol consumption can be made for all patients.

Abstract
BACKGROUND Current heart failure (HF) guidelines note that alcohol use should be discouraged or restricted in patients with HF resulting from left ventricular systolic dysfunction. Existing knowledge is limited in the area of HF and alcohol. METHODS AND RESULTS The purpose of this article is to review the evidence regarding the acute and long-term use of alcohol in the setting of HF. In addition, general aspects about alcohol and alcoholic beverages that are important for understanding and interpreting alcohol-related literature are reviewed and that can be used when discussing alcoholic beverage use with patients with HF. CONCLUSIONS There is some emerging evidence that suggests light drinking (1 to 14 drinks per week) is safe and even beneficial in HF patients with ischemic left ventricular dysfunction (LVD). However, there are no effects of light drinking in HF patients with nonischemic LVD. Clinicians should reinforce the importance of evidence based pharmacologic and nonpharmacologic therapies in HF.

Abstract
OBJECTIVES The study evaluated the relationship between light-to-moderate alcohol consumption and prognosis in patients with left ventricular (LV) systolic dysfunction. BACKGROUND Although chronic consumption of large amounts of alcohol can lead to cardiomyopathy, the effects of light-to-moderate alcohol consumption in patients with LV dysfunction are unknown. METHODS The relationship between light-to-moderate alcohol consumption and prognosis was assessed in participants in the Studies of Left Ventricular Dysfunction (SOLVD), all of whom had ejection fraction values < or = 0.35. Baseline characteristics and event rates of patients who consumed 1 to 14 drinks per week (light-to-moderate drinkers, n = 2,594) were compared with those of patients who reported no alcohol consumption (nondrinkers, n = 3,719). The association between light-to-moderate alcohol consumption and prognosis was evaluated using Cox proportional hazards analysis, controlling for baseline differences and important covariates. RESULTS Mortality rates were lower among light-to-moderate drinkers than among nondrinkers (7.2 vs. 9.4 deaths/100 person-years, p < 0.001). Among patients with ischemic LV dysfunction, light-to-moderate alcohol consumption was independently associated with a reduced risk of all-cause mortality (RR [relative risk] 0.85, p = 0.01), particularly for death from myocardial infarction (RR 0.55, p < 0.001). The risks of cardiovascular death, death from progressive heart failure, arrhythmic death, and hospitalization for heart failure were similar for light-to-moderate drinkers and nondrinkers in this group. Among patients with nonischemic LV dysfunction, light-to-moderate alcohol consumption had no significant effect on mortality (RR 0.93, p = 0.5). CONCLUSIONS Light-to-moderate alcohol consumption is not associated with an adverse prognosis in patients with LV systolic dysfunction, and it may reduce the risk of fatal myocardial infarction in patients with ischemic LV dysfunction.

Abstract
BACKGROUND Alcohol consumption may be linked to syncopal events. The mechanisms by which alcohol may induce syncope are unknown. Impairment of the response to orthostatic stress may be involved. Using a double-blind, randomized, placebo-controlled study, we tested the hypothesis that short-term alcohol intake causes orthostatic hypotension because of an impairment in the vasoconstrictor response to orthostatic stress. METHODS AND RESULTS We examined the effects of alcohol on blood pressure, heart rate, and forearm vascular resistance (FVR) during orthostatic stress achieved by stepwise increases in lower-body negative pressure (LBNP) in 14 healthy young volunteers. During the placebo session, blood pressure did not change significantly during LBNP at -5, -10, and -20 mm Hg. A significant decrease in blood pressure was evident only at -40 mm Hg. In contrast, blood pressure fell significantly at all levels of LBNP during the alcohol session. Compared with placebo, alcohol potentiated the hypotensive responses to LBNP, particularly at -40 mm Hg, when the decrease in systolic blood pressure after alcohol intake (-14 mm Hg) was double that after placebo intake (-7 mm Hg). FVR increased with LBNP after placebo. However, after alcohol intake, FVR did not increase during LBNP despite the potentiated decrease in blood pressure. FVR responses during LBNP were reduced during alcohol compared with placebo consumption (P=0.04). CONCLUSIONS Short-term alcohol consumption elicits hypotension during orthostatic stress because of impairment of vasoconstriction. These findings have implications for the understanding of the hemodynamic effects of alcohol and, in particular, for understanding syncopal events that occur in association with alcohol intake.

Abstract
BACKGROUND AND OBJECTIVE Alcohol has marked effects on hemodynamic and hemostatic variables that might alter the presentation of acute myocardial infarction that follows its use. We sought to determine whether recent alcohol consumption alters the course or complications of acute myocardial infarction. METHODS In the Determinants of Myocardial Infarction Onset Study, we performed chart reviews and face-to-face interviews with 2161 patients who did not receive thrombolytic therapy. We assessed alcohol use before infarction, peak creatine kinase levels (1043 patients), electrocardiographic interpretations (1408 patients), and the presence of ventricular arrhythmias or congestive heart failure (all patients). RESULTS Among the 2161 patients, 399 (18.5%) drank alcohol within 24 hours before myocardial infarction. We found no significant difference in mean peak creatine kinase level between those who had recently used alcohol and those who had not in an adjusted comparison (-6.1% difference; 95% confidence interval [CI] -20.3%-10.7%; P =.46). We also found no differences in adjusted risk for Q-wave infarction, congestive heart failure, or ventricular arrhythmias (odds ratios 1.03 [95% CI, 0.73-1.45; P =.88], 1.01 [95% CI, 0.67-1.54; P =.95], and 1.04 [95% CI, 0.66-1.65; P =.86]). Categorization of the duration since last alcohol use into 6-hour intervals revealed no trends between time since last use of alcohol and any of these outcomes. CONCLUSIONS Recent alcohol use is not associated with changes in infarct size or risk for Q-wave infarction, congestive heart failure, or ventricular arrhythmia among this population.

Abstract
Relapse of congestive heart failure (CHF) frequently occurs and has serious consequences in terms of morbidity, mortality, and health care expenditure. Many studies have investigated the aetiological and prognostic factors of CHF, but there are only limited data on the role of precipitating factors that trigger relapse of CHF. Knowledge of potential precipitating factors may help to optimise treatment and provide guidance for patients with CHF. The literature was reviewed to identify factors that may influence haemodynamic homeostasis in CHF. Precipitating factors that may offer opportunities for preventing relapse of CHF were selected. Potential precipitating factors are discussed in relation to the pathophysiology of CHF: alcohol, smoking, psychological stress, uncontrolled hypertension, cardiac arrhythmias, myocardial ischaemia, poor treatment compliance, and inappropriate medical treatment. Poor treatment compliance in particular is frequently encountered in patients with CHF. Furthermore, studies of medical treatment under everyday circumstances indicate that some aspects of the management of CHF can be improved. In conclusion, the identification of precipitating factors for relapse of CHF may strongly contribute to optimal treatment. Improvement of treatment compliance and optimalisation of medical treatment may offer important possibilities to clinicians to reduce the number of relapses in patients with CHF.

Abstract
Ethanol consumption may induce acute and chronic effects on the myocardium. High-dose acute ethanol intake may induce a decrease in myocardial contraction and produce a variety of rhythm disturbances. These effects are more relevant in patients with underlying cardiomyopathy. Chronic ethanol intake may induce the development of a dilated cardiomyopathy, which is clinically and functionally similar to idiopathic dilated cardiomyopathy. Alcoholic cardiomyopathy is potentially reversible with abstinence. The prognosis depends on the persistence or abstinence of ethanol intake. There is a positive correlation between alcoholic cardiomyopathy and the presence of other ethanol-related diseases, such as skeletal myopathy and cirrhosis. In patients with a specific ethanol-related disease, the possible presence of other complications of alcoholism should be ruled out. Although there are several factors potentially implicated in the pathogenesis of alcohol-related myocardial damage, ethanol itself may induce direct myocardial lesions, which are dose-related and independent of nutrition, protein or ionic deficiencies. The most relevant pathogenic studies on alcoholic cardiomyopathy are based on the disruption of membrane permeability and ionic fluxes mediated by ethanol, inducing a decrease in the calcium transients through the sarcolemma and interfering with the excitation-contraction coupling of myocytes. Cell energy depletion or protein-turnover disruption may contribute to the deleterious effect of ethanol on the myocardium.

Abstract
OBJECTIVE To evaluate the effect of acute alcohol ingestion on myocardial ischaemia in patients with coronary heart disease and stable angina. DESIGN Randomised crossover study using fruit juice with and without ethanol. SETTING Division of cardiology in a university hospital. PATIENTS 20 patients with stable exertional angina and > or = 50% luminal diameter narrowing of at least one major coronary artery. INTERVENTIONS Each patient was studied on two separate days, once after administration of 1.25 g of ethanol per kilogram of body weight diluted to 15% in juice, and once after an equivalent volume of juice; both tests were in the evening and lasted 90 minutes. The patients were scheduled to have 8 periods of walking for 10 min according to a time table. An ambulatory electrocardiogram and the occurrence of anginal attacks were recorded and blood pressure and blood ethanol concentration were measured until the next morning. RESULTS The blood ethanol concentration (mean (SD)) rose to 28.8 mmol/l (1.3 (0.4)/1000). Alcohol raised the systolic blood pressure from 132 (16) to 141 (14) mm Hg (P < 0.05 compared with juice). The mean heart rate increased from 57 (7) to 64 (8) beats/min (P < 0.05) for 13 hours after ethanol ingestion compared with juice. The total duration of ischaemia during the ethanol test was 3.5 (median, range 0-80) min, compared with 0 (range 0-67) min for the juice test (P < 0.05). The difference resulted mainly from more silent ischaemia after ethanol ingestion (2.3 (0-80) v 0 (0-67) min; P < 0.05). The ST segment depression time integral increased during the ethanol test (4.4 (0-170) mm x min) relative to that during the juice test (0 (0-103) mm x min; P < 0.01) and especially during the following 13 hours after alcohol (3.5 (0-123) mm x min) compared with juice (0 (0-67) mm x min; P < 0.005). There were no changes in the number, duration, or ST segment depression time integral of the episodes of symptomatic angina, indicating that ethanol augmented the appearance of silent ischaemia. CONCLUSIONS Acute heavy ethanol drinking aggravates myocardial ischaemia in patients with stable angina pectoris.

Abstract
To investigate the time course of the effects of alcohol on blood pressure, we studied the response of ambulatory blood pressure, neurohumoral variables, and hemodynamics to a single moderate dose of alcohol in hypertensive patients. Sixteen Japanese men (22-70 years old) with essential hypertension who were habitual drinkers were examined under standardized conditions. On the alcohol intake day, they ingested 1 ml/kg ethanol (vodka) at dinner, and on the control day they consumed a nonalcoholic beverage. The order of the two periods was randomized. Mean ambulatory blood pressure was lower in the alcohol intake period than in the control period (125 +/- 3/74 +/- 2 versus 132 +/- 4/78 +/- 2 mm Hg, p less than 0.05), and the significant depressor effect of alcohol lasted for up to 8 hours after drinking. Blood pressure on the next day did not differ with or without alcohol intake. The acute hypotensive effect of alcohol was associated with an increase in heart rate and cardiac output and with a decrease in systemic vascular resistance as determined by echocardiography. Plasma catecholamine levels and renin activity rose significantly at 2 hours after dinner, whereas vasopressin and potassium levels fell on the alcohol day. Blood glucose and serum insulin levels were comparable between the two periods. Three patients with marked alcohol-induced flush had greater hypotensive and tachycardiac responses than those who did not show an alcohol-induced flush. The change in mean blood pressure induced by alcohol was negatively correlated with age, the baseline blood pressure, and the change in plasma norepinephrine. These results indicate that the major effect of acute alcohol intake is to lower blood pressure through systemic vasodilatation in hypertensive subjects. Ambulatory blood pressure monitoring may be useful for assessing blood pressure in habitual drinkers.

Abstract
Transmitral flow velocities were measured by Doppler echocardiography in nine healthy men who ingested 1 g/kg of ethanol within one hour. The measurements were made before the first drink and every hour thereafter for three hours. The peak mean (SE) blood ethanol concentration was 21.4 (1.0) mmol/l. Each man was also studied after drinking fruit juice. Ethanol increased the heart rate but did not change the peak transmitral velocities, the normalised peak filling rate, the deceleration of early flow, or the duration of relaxation as measured from the second heart sound to the peak early diastolic velocity. The ratio of the peak atrial to the peak early diastolic velocity rose from 0.41 (0.03) to 0.44 (0.03) after ethanol but remained unchanged after juice. The difference between juice and ethanol was independent of changes in heart rate. The fluid balance was more negative in the ethanol experiment (-727 (114) ml v -107 (70) ml), suggesting a reduction in preload, and the ethanol-induced net loss of fluid correlated with the concomitant change in the velocity ratio. A moderate dose of ethanol causes a small acute increase of the ratio of the peak atrial to the peak early diastolic velocity of mitral flow in healthy subjects. Although this change indicates altered diastolic function of the left ventricle, most of it may result from the diuretic effect of ethanol. Any major impairment of ventricular relaxation seems unlikely.

Abstract
Alcohol and food intake induce changes in LV performance which can be evaluated by radionuclide cardiographic methods. Alcohol probably exerts its effects by a direct action of ethanol in the blood on the myocardium, while the postprandial hemodynamic changes are related to the effects of food in the intestine. Alcohol intoxication causes a dose-dependent impairment of LV emptying at rest, whereas compensatory mechanisms other than an increased sympathetic nervous activity counterbalance this effect during exercise. In patients with coronary artery disease, alcohol induces only small changes in LV volumes at rest, possibly because of a concomitant vasodilation. Food intake seems to have a considerable influence on central hemodynamics leading to an increase in cardiac output both in healthy subjects and in patients with coronary artery disease. In healthy subjects an increase is recorded in the LVEDV and LVESV after a meal. The autonomic nervous system is probably responsible for most of the hemodynamic changes.

Abstract
The hemodynamic effects of acute alcohol intoxication were studied at rest and during upright exercise in 28 patients with coronary artery disease by right-sided heart catheterization and radionuclide cardiography. The mean arterial blood pressure at rest was reduced by 5% and the left ventricular ejection fraction at rest decreased 2% because of end-systolic dilation during intoxication (serum ethanol 21 mmol/liter). No changes were observed in heart rate, stroke volume, pulmonary artery pressure, pulmonary artery wedge pressure or total peripheral resistance. No significant changes occurred in plasma catecholamines, and no changes occurred in any variable during mild exercise corresponding to a 30 to 40% heart rate increase. Thus, alcohol ingested in moderate doses causes slight impairment of left ventricular emptying and a reduction in the arterial blood pressure at rest in patients with coronary artery disease. A mild exercise load can be tolerated during alcohol intoxication without hemodynamic changes.

Abstract
Trained, chronically instrumented, conscious dogs were used to evaluate the effect of propranolol (PRO), ethanol (ETH) or their combination (P + E) on the left ventricular (LV) function by first-pass radionuclide ventriculography (RNV). Six dogs were trained prior to a sterile left thoracotomy, where a left atrial catheter was implanted. After recovery of four days RNV was carried out by injecting a bolus of technetium-99m diethylenetriamine pentaacetic acid via the catheter to the left atrium. The data was collected for 12 sec. to a computer by frame rate of 20 frames/sec. from left lateral view of the dog. The experiments were performed both in four-leg standing and in 60-degree head-up tilted positions. After control measurements the data were obtained with 0.5 mg/kg of PRO, 0.45 g/kg of ETH and their combination. The P + E combination increased significantly LV end-diastolic and end-systolic volumes, whereas LV peak ejection rate and ejection fraction were decreased. Upright position diminished the LV volume and increased heart rate, while ejection fraction and cardiac output remained unchanged. The first-pass RNV method proved to be promising for measuring the cardiac pharmacological effects in conscious dogs. The combination of propranolol and ethanol in low doses induced an unexpectedly strong depression of LV function, which is supposed to be followed of latent cardiac depressing effect of ETH revealed by blockade of compensatory adrenergic mechanisms with PRO.

Abstract
Ethanol (1, 2 and 3 g/kg, intravenously) decreased the severity of the ischemic arrhythmias in rats with ligation of the left coronary artery and subsequent coronary reperfusion. Reperfusion arrhythmias occurring intensively after occlusion times of 5 and 15 min, respectively, were however not antagonized. Similar results were obtained in isolated perfused rat hearts with final concentrations of 4 and 6 mg ethanol/ml. In rats with reperfusion after 60 min of coronary occlusion, 2 g ethanol/kg significantly reduced the percentage of the ischemic area which underwent necrosis. Moreover, the increase in the wet weight/dry weight ratio of the lungs, as a measure of edema formation, was prevented. The ethanol effects are discussed in the light of present knowledge of the pathogenesis of arrhythmias and myocardial necrosis in experimental myocardial infarction.

Abstract
To evaluate the combined effects of alcohol and nitroglycerin on cardiovascular hemodynamics, M-mode echocardiography and sphygmomanometric blood pressure measurements were performed on two groups of normal subjects, before and after the administration of nitroglycerin, both in the sober state and during alcohol intoxication. In the first part of the study, 0.5 mg of nitroglycerin was given sublingually to 10 healthy volunteers 5-10 minutes after they had ingested 1 g/kg body weight of ethanol within a 30-minute period. Control experiments substituted juice for ethanol. The combined effects of ethanol and nitroglycerin on left ventricular diameters, systolic blood pressure, and wall stress were not significantly different from those of juice and nitroglycerin; heart rate and diastolic blood pressure were increased more (p less than 0.01) by ethanol and nitroglycerin. In the second part of the study, 1.0 mg of nitroglycerin was administered to a second group of 10 healthy volunteers, first in the control state and again 60 minutes after the subjects had ingested 1 g/kg body weight of ethanol within a 60-minute period. Systolic blood pressure and wall stress were significantly lower (p less than 0.01) after ethanol and nitroglycerin than after nitroglycerin before ethanol intake. We conclude that the nitroglycerin-induced reductions in left ventricular preload and afterload are not increased by alcohol during the very early phase of intoxication. However, 1 hour or more after alcohol ingestion nitroglycerin may decrease left ventricular afterload to a level significantly lower than that seen after nitroglycerin in the sober state.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Alcohol has acute and chronic cardiovascular effects. Acutely, alcohol depresses cardiac function and alters regional blood flow. Even when withdrawn from alcohol for several days, alcoholics may still manifest evidence of left ventricular dysfunction. In some alcoholics a severe muscle disorder may ensue with the clinical features of a dilated cardiomyopathy. The concomitant presence of a thiamine deficiency or cirrhosis may produce hemodynamic changes that can obscure the clinical features of alcohol-induced heart muscle disease. Alcoholics may also develop acute myocardial infarction with patent coronary arteries; some may have cardiac arrhythmias even without other evidence of heart disease. Although epidemiological studies suggest that moderate users of alcohol have fewer coronary events than teetotalers, such studies also demonstrate a relation between alcohol abuse and hypertension and an increased occurrence of coronary disease. Thus, the injurious cardiovascular effects of alcohol must be considered when establishing recommendations for its use.

Abstract
The interaction between alcohol abuse, changes in blood pressure, and electrolyte abnormalities is complex. Some effects of alcohol are seen only with acute ingestion, some during withdrawal, and some only in chronic drinkers. Careful attention to the interactions between the metabolism of various electrolytes can prevent unnecessary morbidity and mortality in alcoholic patients.

Abstract
Acute alcohol ingestion can lead to alterations of either mechanical function or electrophysiologic properties of the heart, whereas chronic consumption can lead to progressive cardiac dysfunction and congestive cardiomyopathy. On the other hand, alcohol appears to have a protective effect for coronary artery disease when consumed in low amounts, although prophylactic use of alcohol is not recommended.

Abstract
The aim of this study was to assess whether drinking social amounts of alcohol impairs myocardial contractility in normal humans. To that end, 17 healthy volunteers performed isometric handgrip exercise before and 60 minutes after an intake of 1 g/kg body weight of ethanol within 60 minutes. Left ventricular M-mode echocardiogram, systolic time intervals, and sphygmomanometric arterial blood pressure were recorded before and at the end of 4-min handgrip at 30% of maximum voluntary contraction. The blood ethanol concentration (mean +/- SD) was 24.4 +/- 2.0 mmol/liter. At rest, ethanol increased heart rate (p less than 0.05), and decreased left ventricular end-diastolic diameter (p less than 0.05), end-systolic diameter (p less than 0.01), and circumferential systolic wall stress (p less than 0.05). The indices of left ventricular performance were unchanged except for the maximum circumferential fiber shortening velocity which was increased after ethanol (p less than 0.001). The cardiac response to isometric exercise was similar before and after ethanol except that the handgrip-induced rise in systolic wall stress was smaller postingestion (p less than 0.05). This study does not support the view that drinking small to moderate amounts of alcohol brings about myocardial depression in normal humans. Although preload, afterload, and heart rate were altered by ethanol at rest, myocardial contractility was not impaired even during the afterload stress imposed by isometric exercise.
