Several excellent reviews offer more detailed assessments of vascular cellular mechanisms (Cahill and Redmond 2012; Husain et al. 2014; Marchi et al. 2014; Toda and Ayajiki 2010). Several reports indicate that alcohol first exerts a seemingly positive effect, followed by a more negative impact (i.e., it is biphasic) on the endothelial–nitric oxide–generating system. Endothelial dysfunction is an early indicator of blood vessel damage and atherosclerosis, as well as a strong prognostic factor for future CV events (Deanfield et al. 2007; Ras et al. 2013). Low-to-moderate levels of alcohol consumption may initially improve endothelial function, whereas high daily levels and binge drinking may impair it.
This may also partially explain the abnormal heart rhythm some people experience connected with binge drinking, sometimes known as holiday heart. Its wise to reduce alcohol-consumption and as spirits and wine impact the liver metabolizing renin and angiotensin two hormones vital for controlling hypertension, it makes sense to monitor the effects of alcohol on blood pressure.

However, current recommendations like those from the Centers for Disease Control and Prevention (CDC) focus on limiting alcohol to one drink a day for women and two drinks a day for men. We will combine effect sizes across studies using the fixed‐effect model unless there is substantial statistical heterogeneity between effect sizes. Where there is substantial and unexplained heterogeneity, we will pool data using the random‐effects model. Where trials compare more than one dose of alcohol, each comparison will be handled separately.
In cardiomyocyte mitochondria as well as other mitochondrial types, such imbalances could lead to further decreases in cellular respiration and oxidative phosphorylation. Long-term heavy alcohol consumption induces adverse histological, cellular, and structural changes within the myocardium. These mechanisms contribute to the myocyte cellular changes that lead to intrinsic cell dysfunction, such as sarcoplasmic reticular dysfunction and changes alcohol lowers blood pressure in intracellular calcium handling and myocyte loss. However, modulatory influences related to drinking patterns, genetic susceptibility, nutritional factors, ethnicity, and gender also many play a role (Piano and Phillips 2014) (figure 4). Finally, in studies of people from certain Eastern European countries, investigators have failed to find a cardioprotective effect with any level of ethanol consumption (Britton and McKee 2000).

Investigators have used a variety of noninvasive tests to evaluate the acute effects of alcohol consumption on myocardial function and hemodynamics in healthy humans. As with isolated animal heart experiments, some investigators have found that acute alcohol exposure (blood alcohol levels 40 to 110 mg%) depresses myocardial systolic function in humans (Delgado et al. 1975; Lang et al. 1985; Timmis et al. 1975). However, these changes were transient, with small changes from baseline.
- Moderate‐certainty evidence indicates an increase in heart rate after 7 to 12 hours and ≥ 13 hours after high‐dose alcohol consumption, low certainty of evidence was found for moderate dose of alcohol consumption.
- One common risk factor for CV disease is the composition of the lipids found in the blood, and the effects of alcohol consumption on lipid profiles have been extensively studied.
- B95% confidence interval around the effect estimate includes both appreciable benefit and appreciable harm.
- We conducted a standard Chi² test through Review Manager Software 5.3 to test for heterogeneity (Review Manager (RevMan)).
