Alcohol and Blood Pressure: What to Know

The best way of knowing if there’s a problem is to have your blood pressure measured. You can have this done at your GP surgery, some local pharmacies, at your NHS Health Check or you can buy a reliable blood pressure monitor from the pharmacist. Healthcare professionals may recommend people with hypertension decrease the amount of alcohol they consume. Some researchers are involved in organizations with ties to the alcohol industry. In many ways, your medical history (and present) can tell you a lot about your future with alcohol.

  1. 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).
  2. Based on nine studies, McFadden 2005 reported that the mean increase in SBP was 2.7 mmHg and in DBP was 1.4 mmHg.
  3. The study also didn’t look at how different types of alcohol influenced blood pressure.
  4. This supports the findings from other studies that the alcohol-induced changes in HDL-c do not fully account for the lower risk of CHD in moderate alcohol drinkers (Mukamal 2012).
  5. It has also become clear over time that no amount of alcohol is considered safe for consumption, regardless of the type of alcohol.

Berglund 1989 published data only

Karatzi 2013Maufrais 2017 and Van De Borne 1997 measured blood pressure before and after treatment but did not report these measurements. This review did not find any eligible RCTs that reported the effects of alcohol on women separately. Because women could be affected differently by alcohol than men, future RCTs in women are needed. If future RCTs include both men and women, it is important that their blood pressure and heart rate readings are reported separately. Although eligible studies included East Asian, Latino, and Caucasian populations, they lacked African, South Asian, and Native Hawaiian/other Pacific Islander representation.

Antihypertensive drugs are shown to offer protection against alcohol induced responses in cultured human endothelial cells suggesting the possible involvement of renin-angiotensin system (RAS)[56]. It has been reported that a significant increase in plasma renin activity in patients consuming heavy alcohol compared to mild or moderate alcohol consumption[55,57,58]. However other reports showed no significant in plasma renin activity after alcohol consumption[48,59]. Other studies reported an expansion of the extracellular fluid after alcohol consumption which has been shown to elevate the systolic blood pressure in rats[60,61]. Chan et al[60] have proposed that expansion of the extracellular fluid is the result of elevated plasma vasopressin levels and plasma renin activity, indicating increased sympathetic stimulation.

Research shows that the polyphenols improve the cells lining the blood vessels, and do improve blood flow and heart health. The jury is still out, though, on whether this could potentially improve high blood pressure in severe cases. The type of alcoholic beverage also determines the impact on health, with red wine being considered eco sober house review healthy, for instance, due to the high polyphenol content. Most importantly, masked hypertension, where patients are hypertensive at home but not in the doctor’s office, is as serious a health risk as sustained hypertension. In various biologic systems, oxidative stress can be measured or inferred by several biologic indexes.

Only four studies included almost equal numbers of male and female participants (Buckman 2015; Foppa 2002; Maufrais 2017; Zeichner 1985). As a result, we were not able to quantify the magnitude of the effects of alcohol on men and women separately. This is unfortunate, as we have reason to believe that the effects of alcohol on BP might be greater in women. For medium doses of alcohol, moderate‐certainty evidence shows a decrease in SBP and DBP six hours after alcohol consumption, and low‐certainty evidence suggests a decrease in SBP and DBP for 7 to 12 hours after alcohol consumption.

Any disagreements regarding inclusion or exclusion of studies were resolved by discussion between review authors. The reason for exclusion was documented for each citation at the full‐text level. We also checked the list of references in the included studies and articles that cited the included studies in Google Scholar to identify relevant articles. We included 32 randomised controlled trials involving 767 participants published up to March 2019. Although these trials included adults from 18 to 96 years of age with various health conditions, most study participants were young healthy males. The AHA states even people who drink one alcoholic beverage per day showed a link to higher blood pressure compared to non-drinkers.

Notably, the heart attack risk was in inverse relation to alcohol consumption levels. With moderate doses of alcohol, blood pressure (BP) went up for up to seven hours but normalized after that. A biphasic response was observed with high doses of alcohol, with an initial decrease in both systolic and diastolic blood pressure (SBP and DBP, respectively) for up to 12 hours, increasing at more than 13 hours from consumption.

However, the negative associations between alcohol consumption and CV outcomes in these countries also may relate to pervasive patterns of binge drinking (Leon et al. 2009). More recently, Cosmi and colleagues (2015) examined the effects of daily wine consumption in subjects enrolled in an Italian stimulant overdose drug overdose cdc injury center 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).

The autophagy pathway also is rapidly upregulated during ATP depletion, mitochondrial dysfunction, and oxidative stress. Ethanol-mediated increases in autophagy therefore may be an important mechanism underlying the adverse myocardial effects of ethanol. More contemporary studies have not found evidence of mitochondrial injury in biopsy samples from long-term alcohol drinkers (Miró et al. 2000). Differences among results from human studies may relate to small sample sizes, duration of drinking, and degree of myocardial dysfunction.

The vagus nerve is a component of the parasympathetic nervous system and is largely responsible for regulation of the heart rate at rest. Rossinen 1997 and Van De Borne 1997 reported withdrawal of vagal tone and reduced heart rate variability within an hour after alcohol consumption; this explains the increased heart rate. Buckman 2015, Van De Borne 1997, and Fazio 2001 adult children of alcoholics also reported reduced baroreflex sensitivity following alcohol consumption. Impairment of baroreflex sensitivity results in failure to sense the increase in heart rate and maintenance of cardiovascular homeostasis. Kawano 2000 reported a reduction in plasma potassium levels after alcohol consumption, which might provide another reason for the increase in heart rate.
