As a result, further research is necessary to confirm the effects on all people. If you hope that moderate drinking is good for you, that idea is falling out of favor. She notes that it can cause an enlarged heart (alcoholic cardiomyopathy), which weakens your heart and makes it harder to pump blood.
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 Sobriety 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.
The decrease in SBP was greater with 30 g of alcohol seven hours after consumption compared to placebo and 15 g and 60 g alcohol‐consuming groups. In this study, alcohol had no significant effect on DBP in the four groups. Medium‐dose alcohol decreased systolic blood pressure (SBP) by 5.6 mmHg and diastolic blood pressure (DBP) by 4 mmHg within the first six hours of consumption. Alcohol has been a part of almost every human culture for a very long time (McGovern 2009).
For the purposes of this review, if I² was greater than 50%, it was considered to show a substantial level of heterogeneity. Furthermore, we visually inspected the forest plot to check whether there were any non‐overlapping confidence intervals indicating heterogeneity. Last, we attempted to explore the reason for heterogeneity by looking for clinical and methodological differences between trials. We contacted the study authors for missing or unclear information relevant to the review using contact information provided in their respective articles. If the dose of a study was not reported in the article and the study author did not respond to our request, we excluded that study. Studies published in the American Heart Association’s scientific journals are peer-reviewed.
For low doses of alcohol, we found low‐certainty evidence suggesting that SBP, DBP, and MAP fall within the first six hours after alcohol consumption. Rosito 1999 reported the effects of 15, 30, and 60 g of alcohol compared to placebo on healthy male volunteers. According to our pre‐specified dose categories, both 15 g and 30 g of alcohol fell under the medium dose category. Including both of these doses or de‐selecting either one of these doses from Rosito 1999 from Analysis 2.1 and Analysis 2.2 (medium doses of alcohol) resulted in the same statistically significant conclusion. High‐dose alcohol consumption increased HR by approximately 6 bpm in participants, and the effect lasted up to 12 hours. For selective reporting for heart rate (HR), we classified only Koenig 1997 as having high risk of bias because heart rate was not reported.
For medium doses and high doses of alcohol, participants represented a range in terms of age, sex, and health condition. Because the participant population comprised predominantly young and healthy normotensive men, the overall evidence generated in this review cannot be extrapolated to women and older populations with other comorbidities. In the case of detection bias, we classified nine studies as having low risk of performance bias (Agewall 2000; Bau 2005; Bau 2011; Cheyne 2004; Dai 2002; Karatzi 2013; Narkiewicz 2000; Rosito 1999; Van De Borne 1997). All studies included an independent individual who was blinded to control and test groups to evaluate and analyse the data.
Recent research suggests that automated ambulatory blood pressure monitors are more reliable than manual sphygmomanometers, particularly because automated monitors reduce white coat anxiety (Mirdamadi 2017). Of the 32 included studies, seven studies used a manual mercury sphygmomanometer or a semi‐automated sphygmomanometer for BP measurement (Bau 2005; Dai 2002; Karatzi 2005; Kojima 1993; Potter 1986; Rossinen 1997; Van De Borne 1997). Mixing of various measurement techniques (manual, semi‐automated, and fully automated) in the meta‐analysis might have led to some of the heterogeneity. For multi‐arm trials, if a study reported more than one intervention arm, we identified the relevant intervention arm and included that in the review. If studies reported more than one placebo group, we combined them into a single group when appropriate, using the formulae for combining groups reported in Chapter 7 of the Cochrane Handbook for Systematic Reviews of Interventions (Higgins 2011). We followed the same formulae for combining groups if a study =https://ecosoberhouse.com/ reported two different types of alcoholic beverages containing the same amount of alcohol.
This review summarises the acute effects of different doses of alcohol on blood pressure and heart rate in adults (≥ 18 years of age) during three different time intervals after ingestion of alcohol. To determine short‐term dose‐related effects of how does alcohol affect blood pressure alcohol versus placebo on systolic blood pressure and diastolic blood pressure in healthy and hypertensive adults over 18 years of age. Another non-pharmacological prevention and treatment of alcohol-induced hypertension is physical conditioning or exercise training.
Karatzi 2013Maufrais 2017 and Van De Borne 1997 measured blood pressure before and after treatment but did not report these measurements. Several studies reported increased sympathetic nervous system activation and discharge of sympathetic amines after alcohol consumption43,48,49. Alcohol may cause hypertension by affecting the autonomic nervous system50. However, alterations in the sympatho-adrenal function that occur during ageing may cause older people to have a different reaction to factors triggering their autonomic system than do younger individuals51. The increased sympathetic outflow is expected not only to induce adrenoreceptor-mediated reactions (vasoconstriction, heart rate increase) but to stimulate oxidation reactions43.
