Factors influencing blood pressure in chronic alcoholics
Insights
Alcohol-induced hypertension is common during alcohol withdrawal, affecting nearly half of patients. Blood pressure normalizes as withdrawal symptoms subside, highlighting the transient nature of this hypertension.
Area of Science:
- Cardiology
- Addiction Medicine
- Internal Medicine
Background:
- Hypertension is a significant health concern, and its relationship with alcohol use requires further investigation.
- Alcohol withdrawal syndrome (AWS) is a complex physiological state with various associated symptoms.
Purpose of the Study:
- To investigate the prevalence and characteristics of hypertension in patients undergoing alcohol detoxification.
- To explore the relationship between hypertension, alcohol withdrawal severity, and long-term alcohol consumption patterns.
Main Methods:
- Prospective study of 96 patients admitted for alcohol detoxification.
- Monitoring of blood pressure (systolic and diastolic) and severity of alcohol-withdrawal symptoms.
- Follow-up assessment of blood pressure in relation to alcohol abstinence or relapse.
Main Results:
- 48% of patients exhibited hypertension during detoxification (BP > 140/90 mmHg).
- Elevated blood pressure correlated with the severity of alcohol-withdrawal symptoms.
- Hypertension resolved in most patients (91%) after withdrawal symptoms abated.
- Blood pressure remained normal with abstinence but increased upon relapse to drinking.
- No consistent link was found between hypertension and alcoholic liver disease severity.
Conclusions:
- Alcohol-related hypertension is frequently observed during the acute alcohol-withdrawal syndrome.
- The likely mechanism involves increased noradrenergic activity associated with withdrawal.
- Maintaining alcohol abstinence is crucial for managing alcohol-related hypertension.
Abstract:
1. Of 96 alcoholics admitted for detoxification, 48% were hypertensive (systolic blood pressure greater than 140 mmHg and/or diastolic pressure greater than 90 mmHg). 2. Elevation of both systolic and diastolic blood pressures was related to the severity of alcohol-withdrawal symptoms. 3. After these symptoms had abated only 9% of patients remained hypertensive. 4. Blood pressure remained normal if patients abstained from alcohol after discharge but rose in those who started drinking again. 5. Hypertension was not consistently related to the presence or severity of alcoholic liver disease. 6. Alcohol-related hypertension may be the result of the alcohol-withdrawal syndrome; increased noradrenergic activity is suggested as the likely mechanism.
