Consumption of alcohol and blood pressure: Results of the ELSA-Brasil study PLOS ONE

For example, sympathetic activation could underlie the observed https://ecosoberhouse.com/ elevation, as could the disruption of carotid baroreceptor responses that regulate BP. This disruption might be due to higher amounts of endorphins and histamine released by alcohol. However, people who are dependent on alcohol or have been misusing alcohol for a long period of time may have difficulty quitting. When blood pressure decreases, these receptors help minimize how much the blood vessels stretch to increase blood pressure. Similarly, when blood pressure increases, these receptors increase the stretching of the blood vessel walls in order to decrease blood pressure. Alcohol increases blood levels of the hormone renin, which causes the blood vessels to constrict.

The Alcohol Dependence Scale12 was self-administered at the first screening visit to exclude candidates who evidenced manifestations of alcohol dependency, since it was considered unethical to withhold some form of intervention from dependent drinkers. The primary alcohol eligibility criterion was based on a structured interview instrument administered at the second screening visit. To be eligible a participant must have reported consumption of an average of at least 21 drinks per week in the most recent 6 months. The type of alcoholic beverage also determines the impact on health, with red wine being considered 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.

Polyphenols may help with health issues related to digestion, heart problems and diabetes, and eating themmay reducepeople’s risk of hypertension. However,one studyshowed that one drink of alcohol was capable of lowering blood pressure, regardless of whether it was red wine or another type of alcohol, meaning that any type of alcoholic drink can positively impact a person’s blood pressure. The results of PATHS should not alter recommendations that individuals with, or at risk of, hypertension should consume no more than an average of 1 to 2 drinks per day. In addition, more research is needed on biochemical indexes as markers for change in alcohol intake within the range studied herein. Average BP at each time period by treatment group is displayed in Figure 3 for all participants and for the hypertensive stratum. For the entire study, the larger differences in BP change from baseline were seen at 3, 12, and 24 months, significantly greater in the intervention group for DBP at 12 and 24 months . For the hypertensive stratum the only significant difference was for SBP at 3 months .

High‐dose alcohol consumption increased HR by approximately 6 bpm in participants, and the effect lasted up to 12 hours. After that, HR was still raised in participants, but it averaged 2.7 bpm.

On the other hand, other research has shown that there may be a link between alcohol and low blood pressure for people who drink one glass of alcohol a day. The evidence from investigations with various designs converge regarding the acute biphasic effect of ethanol on BP and the risk of chronic consumption on the incidence of hypertension, particularly for Blacks. These effects do not support the putative cardioprotective effect of consumption of low-to-moderate amounts of alcoholic beverages. Mechanisms of chronic BP increase and the demonstration of long-term benefits of reducing alcohol intake as a means to treat hypertension remain open questions.

  • There is likely a dose‐response effect of alcohol on BP, as the effects of alcohol appeared to last longer with higher doses.
  • Exceeding this limit increases the risk of cardiovascular, hepatic, and nervous system disorders (Bellentani 1997; Fuchs 2001; Gao 2011; Lieber 1998; McCullough 2011; Nutt 1999; Welch 2011).
  • If you drink, limit your alcohol consumption to no more than two drinks per day for men and no more than one drink per day for women.
  • In contrast, non-ABP average BP recorded at a similarly long follow-up did reach significance.
  • The diagnosis of abdominal obesity was established from the following WC values ≥80 and ≥94 cm for women and men, respectively .
  • We used Cochrane review manager software for all data analyses (Review Manager ).

Although eligible blood pressure and alcohol included East Asian, Latino, and Caucasian populations, they lacked African, South Asian, and Native Hawaiian/other Pacific Islander representation. Most of the hypertensive participants in the included studies were Japanese, so it is unclear if the difference in blood pressure between alcohol and placebo groups was due to the presence of genetic variants or the presence of hypertension. Large RCTs including both hypertensive and normotensive participants with various ethnic backgrounds are required to understand the effects of alcohol on blood pressure and heart rate based on ethnicity and the presence of hypertension.
