Alcohol Consumption and Cardiovascular Disease Risk: Placing New Data in Context PMC

They described an increased risk for hypertension in lifetime abstainers and a reduced risk in the less-heavy consumption group; nonetheless, when adjusted by a propensity score method, these findings were not significant. Current drinkers who drink 5 or more drinks/day at least monthly did show a significant risk of hypertension, meaning that consistent long-term heavy drinking is the real after the high the dea cause [60]. It’s also more likely to occur in people who have risk factors such as high blood pressure, heart disease, obesity, European ancestry or a family history of arrhythmias. About four decades ago, doctors began documenting cases of people experiencing arrhythmias after bouts of heavy drinking on weekends and holidays, a phenomenon that came to be known as holiday heart syndrome.

Long-term Effects

For example, despite the findings about moderate drinking and Afib risk, many studies have found lower rates of cardiovascular disease among people who drink moderately. Yet daily drinking that becomes excessive can increase your risk for high blood pressure, stroke and, importantly, obesity, which also increases your risk for Afib. Behavioral risk factors such as overweight and obesity, poor diet, sedentarism or low physical activity, excessive alcohol consumption, and smoking have been correlated with a higher incidence and prevalence of CVD, how long does ecstasy mdma stay in your system diabetes, and dementia [8,14,15]. A recent systematic review reported that non-smoker individuals, with a moderate alcohol consumption, who were physically active and followed a healthy diet showed a lower risk of all-cause mortality (66%) than those that had none or only one of these healthy behaviors [15]. Ford et al. [8] reported similar results, showing that non-smoker individuals following a healthy diet and who were physically active presented a lower risk of mortality by CVD (65%) than those that have none of these healthy behaviors.

  2. While some people develop a tolerance to alcohol over time, this isn’t true for everyone — and this ability doesn’t last forever, Dr. Cho notes.
  3. Long-term alcohol use can change your brain’s wiring in much more significant ways.
  4. Back home, if you start drinking regularly again and your blood pressure changes, your GP can alter your medications.

Is some level of alcohol safe or beneficial?

Both experimental approaches also prevented accumulation of ethanol-induced scarring (collagen and fibronectin); apoptotic cell death; and changes in the size, shape, and function of the heart after injury to heart muscle (ventricular remodeling). More recently, Cosmi and colleagues (2015) examined the effects of daily wine consumption in subjects enrolled in an Italian trial of heart failure patients (mean age ~67), most of whom had reduced ejection-fraction heart failure. Different levels of daily wine consumption (i.e., sometimes, 1 to 2 glasses/day, and ≥3 glasses/day) had no effect on fatal or nonfatal outcomes (e.g., hospitalization for a CV event).

Alcohol’s Effects on the Cardiovascular System

Since then, a number of large observational studies have found that people who regularly consume alcohol, even as little as one drink a day, have an increased likelihood of going on to develop atrial fibrillation compared with people who abstain. Although results related to levels of alcohol consumption and stroke events are less clear, some conclusions can be drawn. Approximately 1 to 2 drinks per day may have no effect on or lead to a slight reduction in stroke events; however, greater daily alcohol levels increase the risk for all stroke events and incident stroke types. In terms of stroke subtypes, compared with nondrinkers, current alcohol drinkers have an increased risk (~14 percent) for hemorrhagic stroke (Ronksley et al. 2011). It should also be noted that due to the limitations of alcohol-epidemiological studies, the beneficial associations tend to be overestimated.

We and our partners process data to provide:

All told, drinking alcohol in excess is the third-leading cause of preventable death in the United States. Instead, factors that coincided with moderate drinking, such as favorable lifestyle choices and, in some cases, the socioeconomic environment, were responsible. As such, evidence instead suggests that drinking alcohol in any amount can be harmful. Moderate drinking — one drink a day for women and two for men — appears to protect some people against heart disease. Figure 3 summarizes the potential mechanisms underlying the cardioprotective and adverse effects of alcohol consumption. This area of research was briefly outlined here; more comprehensive reviews on these mechanisms are available (Krenz and Korthuis 2012; Mathews et al. 2015).

A second caveat to consider is the “sick quitter” phenomenon, whereby abstainers (the referent category in many studies) include a mixture of long-term abstainers and those who have quit due to pre-existing illness. This results in an artificial elevation of the health risk among abstainers, in which it is not the absence of alcohol but impaired health status that increases the observed elevated risk [25, 41–50]. Epidemiological studies indicate a complex relationship between various dimensions of alcohol consumption (i.e., life course drinking patterns) and CVD outcomes. Most epidemiological studies to date have relied on a single measurement of alcohol intake at baseline.

After a person undergoes heart surgery, it is best to ask the doctor how much they should drink, as this could depend on individual circumstances and medical history. These usually come with a warning sticker from your pharmacy that tells you not to drink while you take them. One drink is 12 ounces of beer or wine cooler, 5 ounces of wine, or 1.5 ounces of 80-proof liquor. There are several actions that could trigger this block including submitting a certain word or phrase, a SQL command or malformed data. In many ways, your medical history (and present) can tell you a lot about your future with alcohol. That means, if you’re living with other medical conditions and/or taking certain medications, this will all have an impact on how alcohol affects you.

A J-shaped relationship for females showed protective effects at or below consumption levels of 15 g/day (Taylor et al. 2009). These data highlight how gender may be an important modifier of the alcohol threshold level and can shape the alcohol benefit–risk relationship. Another trend in recent studies of alcohol and CV risk and disease is to include a measurement for binge drinking.

According to 2022 research, any amount of alcohol can have a negative impact on the heart and cardiovascular system. The Dietary Guidelines for Americans recommends that people avoid drinking when possible. However, if someone wants to drink, it is best to stay within the recommended limits. Historically, some studies suggested that when people drank alcohol moderately, they experienced protective cardiovascular benefits.

Due to the limitations of typical epidemiological studies, other types of study design, such as Mendelian randomization studies using an instrumental variable approach, sought to answer questions about the causality of the lower risk of low-level alcohol drinkers. However, the use of such an approach [45,46], which depends on several assumptions that are not easily met in a complex relationship, such as between alcohol consumption patterns and CVD risk, is highly debated [47,48,49,50]. 3In this article, the term “moderate drinking” generally refers to the consumption of one or two drinks per day. Moderate drinking cannot be achieved by simply averaging the number of drinks consumed, however.

The authors speculated that the findings could have broader implications for healthy adults as well. Although moderate drinking is widely considered beneficial for heart health, the new research suggests that, at least in some people, it could potentially disrupt how the heart functions. The scientists found that drinking alcohol heightened the odds that a person would have an episode of atrial fibrillation, or an abnormal heart rhythm, within the next few hours. The conclusions, along with data from previous studies, suggest that people with a history of atrial fibrillation could reduce their chances of developing arrhythmias by cutting back on alcohol or avoiding it altogether. Ethanol-induced changes may be related to oxidative or nonoxidative pathways of ethanol metabolism.

And while enjoying celebratory spirits in moderation is alright for most people, it’s important to be aware you can fall victim to holiday heart syndrome if you overdo it. This is when overeating and overindulging in alcohol lead to an irregular heartbeat. On average, a regular heart rate is about 60 to 100 beats per minute when your body is at rest. But alcohol can lead to your heart rate temporarily jumping up in speed, and if it goes over 100 beats per minute, it can cause a condition called tachycardia.

Daily RW consumption for 21 consecutive days significantly enhanced vascular endothelial function in 20%. Although plasma stromal cell-derived factor-1 (SDF-1) concentrations remained unchanged, the endothelial progenitor cell (EPC) count and migration significantly increased after this period. RW increased the migration, proliferation, C-X-C chemokine receptor type 4 (CXCR-4) expression, and the activity of the alcohol and migraine drinks to avoid, remedies, and more Pi3K/Akt/eNOS signaling pathway and decreased the extent of apoptosis in glucose-stressed EPCs [36]. These factors combine to result in a lower rate of cardiovascular disease in people who drink moderate amounts of alcohol than in people who do not drink alcohol at all. In addition to the heart benefits, moderate alcohol intake can slightly lower your risk of type 2 diabetes, stroke and Alzheimer’s disease.

Your central nervous system consists of the brain, spinal cord, and neurons that communicate messages throughout your body. It powers key functions and processes like movement, memory, speech, thought processes, and more. A comprehensive 2015 review found that alcohol use is one of the leading contributors to pancreatitis because it causes the pancreas to produce toxic substances.

In addition, while such studies are innovative and potentially informative, they are not free of their own limitations and caution is equally required when interpreting the results of these new studies. In a meta-analysis of 11 cohorts published in 2014, an inverse risk relationship between average alcohol consumption and IHD in patients with hypertension was reported [37]. Similar associations have been reported among people with diabetes and non-fatal myocardial infarction [38,39,40,41,42]. A recent large-scale study from the UK reported a J-curve for most CVD outcomes in patients with CVD [43].
