Quantity Is A Key Factor When It Comes To Alcohol And Heart Health

Top Ways How Alcohol Affects Blood Pressure You Never Knew About.

While moderate amounts of alcohol can offer some heart benefits, too much can have damaging effects.

For instance, the more alcohol you drink at one time, the higher your heart rate gets, according to research from the European Society of Cardiology. A sudden spike in heart rate is potentially dangerous to people with heart conditions, as it could trigger arrhythmias .

A study in the April 14, 2018, issue of The Lancet looked at the drinking habits of almost 600,000 people without heart disease, and found that people who had 10 or more drinks per week died one to two years earlier compared with those who drank five drinks or fewer per week. Having 18 drinks or more per week cut life expectancy by four to five years.

Alcohol Consumption For Someone With High Blood Pressure

If someone has high blood pressure, they should avoid drinking alcohol as much as possible. Most doctors recommend that people with high blood pressure should exercise and eat a healthy diet. Part of this healthy diet is avoiding alcohol use.

While alcohol does contribute to high blood pressure, it may be safe to use small amounts of alcohol. The American Heart Association says the maximum daily amount of alcohol consumption for people with hypertension is two drinks for men and one drink for women. Ultimately, the less you drink, the better it will be for your hypertension. The AHA recommendations may not work best for everyone, however, so be sure to speak with a doctor about your specific situation.

Ask The Doctor: Does Heart Rate Affect Blood Pressure

Q. When doctors interpret a blood pressure reading, should they also consider the heart rate? I am a 78-year-old man and have had high blood pressure for more than 40 years. I frequently monitor my blood pressure at home, resting for five minutes before I take the reading. My blood pressure is often higher when my heart rate is close to its usual resting rate and lower when my heart is beating faster than that. Can the body’s demands that cause higher blood pressure be partially satisfied by a faster heart rate?

A. First, let me congratulate you on monitoring your blood pressure at home. This is a great way for you to take control of your high blood pressure, and a good step toward preventing a stroke. Knowing that your blood pressure at home is under consistent control is more important than getting isolated readings at the doctor’s office. You are also resting before taking the reading, and this is important to avoid spuriously high readings that happen when someone rushes around, and then sits down quickly to take a blood pressure reading.

Why Does My Heart Beat Irregularly After Drinking White Wine

Some people find that particular types of alcoholic drinks impact them more than others. Wine, both red and white wine, are reported to cause many people with uncomfortable symptoms.

A glass of wine contains a chemical called tannins. If youre sensitive to this chemical, you might experience headaches, irregular heart rate or a stuffy nose . Wine also has a fair amount of histamines, which can trigger an allergic response in some.

If you reaction to wine is severe, its important to talk to a medical professional before drinking again. Although a true allergy to alcohol is rare, its still possible and could be serious. Or you might find that you have an allergy to an ingredient used in wine and should pick other alcoholic drinks without that ingredient. If you can avoid that particular ingredient, additive or preservative, your reaction might be reduced or stop completely.

Heart / High Blood Pressure Medications With Alcohol

5 Ways Alcohol Affects Your Heart

Medically reviewed by Leigh Ann Anderson, PharmD. Last updated on Nov 23, 2019.

Many of us combine alcohol with our heart medications. But can you safely drink alcohol with high blood pressure or other heart medications? This is a drug interaction question you might ask your doctor or pharmacist because use of heart medication is so common. Let’s look more closely.

Cardiovascular medications are widely prescribed to prevent or treat disorders of the cardiovascular system, such as:

They might also be used to treat other non-heart conditions like migraine headache or essential tremor.

In one study, Breslow and colleagues reported that out of roughly 17,000 drinkers, heart medications were the drug class with the highest percentage of possible alcohol interactions, at about 24 percent. Alcohol and blood pressure medication interactions comprised a large percentage of this group.

Alcohol itself may also lower blood pressure itself in some patients. Theoretically, a high blood pressure medication and alcohol consumption might worsen low blood pressure and lead to side effects like dizziness, lightheadedness, drowsiness, fainting, or falling.

    New Methods For Analyzing Alcohol Consumption And Stroke

    Investigators are using new methods to examine the relationship between alcohol consumption and CV outcomes. One such method includes Mendelian randomization, an epidemiologic study design that incorporates genetic information into traditional epidemiologic methods. Mendelian randomization offers an opportunity to test the relationship between a causal factor and a specific outcome . used Mendelian randomization to determine if a relationship exists between drinkers with a certain variant in the alcohol dehydrogenase ADH1B gene , which is associated with reduced alcohol consumption, and the likelihood of having fatal or nonfatal CHD and stroke. The investigators found that individuals with the A allele variant ADH1Brs1229984 consumed less alcohol and had a reduced risk of CHD and ischemic stroke compared with noncarriers. This implies that lower alcohol consumption, even in light-to-moderate drinkers, was beneficial for CV health. These results challenge the findings from several of the studies mentioned earlier that support a cardioprotective effect of low-to-moderate alcohol consumption. They also suggest that traditional epidemiologic studies may not capture important nuances related to selection bias or other errors that can affect study results .

    Can You Get High Blood Pressure From Drinking Alcohol

    Drinking alcohol has the potential to increase blood pressure in most individuals. Drinking more than three drinks in a single session can lead to a short-term increase in blood pressure. Excessive, long-term alcohol consumption and repeated binge drinking can lead to more sustained rise in blood pressure .

    In both cases, systolic blood pressure and diastolic blood pressure can reach unhealthy levels and put you at risk of heart-related complications. Those who already have high blood pressure have an even higher risk of developing hypertension complications from alcohol consumption.

    Many people are still at risk of developing high blood pressure from drinking any amount of alcohol, regardless of prior health status.

    Alcohol And Heart Health: Whats The Real Story

    The problem with most alcohol-related research is that it consists almost entirely of observational studies that only show an association, according to Dr. J. Michael Gaziano, a preventive cardiologist with Harvard-affiliated Brigham and Womens Hospitals Division of Aging and VA Boston.

    So far, the strongest evidence with heart health has shown that alcohol can increase levels of HDL cholesterol. HDL works to keep LDL cholesterol from clogging your arteries by moving it to the liver, where its broken down and removed from the body. Many studies have found that the combination of high HDL and low LDL levels protects against heart attacks and stroke. However, this is not the most important factor in preventing heart disease, and there are other ways to increase HDL than drinking alcohol, such as regular exercise, says Dr. Gaziano.

    Measurements Of Blood Pressure And Heart Rate

    Details on the methods used for measuring systolic and diastolic blood pressure and resting heart rate in each study are provided in . In cohorts where information about use of blood pressure lowering medication was available a constant was added to SBP and DBP in subjects on blood pressure lowering medication as recommended by Tobin and colleagues. If this information was not available SBP and DBP were analysed as they were. Availability of information on blood pressure lowering medication in each study is provided in . The following dichotomous outcomes were defined: 1) hypertension as SBP > 140 mmHg or DBP > 90 mmHg or taking blood pressure lowering medication, 2) severe hypertension as SBP > 160 mmHg or DBP > 100 mmHg, or taking blood pressure lowering medication. Thus, participants taking blood pressure lowering medication were defined as having both hypertension and severe hypertension. BMI was calculated as weight/height2 . Age was calculated as years at the time of measurements of blood pressure and heart rate.

    More Alcohol Means More Risk

    A recent study found a strong link between drinking one to three drinks a day and getting AFib.

    Heavy drinking, or more than three drinks a day, bumps up your risk even more. And it seems to keep going up the more you have. Studies suggest that for every extra daily drink, your risk goes up by 8%.

    You don’t have to drink regularly, either. Binge drinking, or having more than five drinks in a row, also makes getting AFib more likely. People in these studies drank wine or hard liquor. It’s not clear if beer has the same effect.

    Does Excessive Drinking Contribute To Heart Disease

    Heavy drinking, on the other hand, is linked to a number of poor health outcomes, including heart conditions. Excessive alcohol intake can lead to high blood pressure, heart failure or stroke. Excessive drinking can also contribute to cardiomyopathy, a disorder that affects the heart muscle.

    Whats more, alcohol can contribute to obesity and the long list of health problems that can go along with it, McEvoy says: Alcohol is a source of excess calories and a cause of weight gain that can be harmful in the long term.

    The takeaway, McEvoy says, is what you probably already knew: If you choose to drink alcohol, stick to moderate levels of drinking, and dont overdo it. Were not talking about going out and drinking yourself merry and then expecting good heart outcomes, McEvoy says.

    Alcohol And Symptoms Of Hypertension And Hypotension

    How does alcohol affect blood pressure? An investigation has shown there to be a strong association between the two factors although, the symptoms may be difficult to detect. Its also important to consider why does alcohol raise blood pressure? Hypertension is often known as the silent killer, and regular tests should be requested when alcoholism is a factor or if any of these symptoms are experienced.

    • Headaches
    • Difficulty drawing breath
    • Blurred vision

    It makes sense to reduce common risk-factors of alcohol and blood pressure and to try to break the addictive hold of alcoholism. Note that the elevated blood pressure may also be one of the alcohol allergy symptoms.

    Low blood pressure must also be considered as a risk.

    Symptoms include:

    Arteries tighten restricting blood flow due to escalating pressure. Dizziness or fatigue results. Staying hydrated if hypotension is present is all-important. Its wise to reduce alcohol-consumption and as spirits and wine impact the liver metabolizing renin and angiotensin two hormones vital for controlling hypertension, it makes sense to monitor the effects of alcohol on blood pressure.

    Drinking Can Increase The Risk Of An Immediate Cardiac Event

    While moderate or safe alcohol consumption is certainly better than consuming large quantities of alcohol, it does not necessarily prevent potential heart and other health conditions. In fact, studies have found that any alcohol consumption can increase a persons risk for an immediate cardiovascular event over the following 24 hours after drinking.

    However, moderate drinking may also act as a protectant against cardiovascular events for the week following moderate alcohol consumption. A study found that moderate drinkers or individuals that consume four or fewer drinks in one sitting were up to 30 percent less likely to experience a hemorrhagic stroke or myocardial infarction in the seven days after drinking.

    Conversely, heavy alcohol consumption can significantly increase a persons risk for cardiovascular problems in the week following drinking. In fact, consuming 19 to 30 drinks in one week can cause a person to be up to six times more likely to experience a cardiovascular event within a week.

    Why Does Your Heart Race When You Drink Alcohol

    How, exactly, does alcohol increase heart rate? And arent some types of alcohol supposed to be good for the heart?

    It appears that small amounts of alcohol may have some positive effect on your circulatory system. But the more you drink, the more those effects are overshadowed by other factors that put extra stress on your heart.

    A small, real-time study2 compared the effect of one vs two servings of alcohol in healthy volunteers. In the results, one drink appeared to dilate blood vessels, helping reduce how hard the heart had to work. But two drinks seemed to have the opposite effect, decreasing artery dilation while also increasing:

    • Sympathetic nervous system activity
    • The amount of blood pumping through the heart

    In other words, the more people drank, the harder the heart had to work to overcome the effects of alcohol. This may also partially explain the abnormal heart rhythm some people experience connected with binge drinking, sometimes known as holiday heart.

    Interestingly, despite red wine having a reputation for improving heart health, the study found no difference between this and other types of alcohol.

    Alcohol And Blood Pressure: What Are The Effects

    Disclaimer: Results are not guaranteed*** and may vary from person to person***.

    The relationship between the long-term use of alcohol and blood pressure levels is a major medical concern as alcoholic drinks are commonly consumed by most cultures in the world, and one in eight American adults suffer from alcohol abuse.

    Chronic alcohol consumption can have damaging effects on the liver, digestive tract, and vascular system, which leads to elevated blood pressure levels. This increases the risk for serious cardiovascular issues, like heart attack and stroke.

    The link between alcohol and blood pressure levels was first documented in the early 1900s. Dozens of studies since then have worked to establish the physiological mechanism behind the relationship, and research is still ongoing.

    Alcohol Chd And Stroke

    The relationship between and among alcohol consumption, CHD, and stroke has been extensively investigated. Many of these studies have been conducted in middle-aged and older people and across populations. These studies have used ecologic designs casecontrol designs and longitudinal research designs . Examples include the Health Professionals Follow-up Study , the Nurses Health Study , the Framingham Heart Study , the British Doctors Study, the Physicians Health Study, the Copenhagen City Heart Study , and INTERHEART . The availability of these diverse datasets has allowed for completion of several comprehensive systematic reviews and meta-analyses of alcohol, CHD, and stroke relationships. This section summarizes data from meta-analyses, along with data from large international studies such as INTERHEART and other recent studies using new methodologies such as Mendelian randomization .

    Who Is At Most Risk

    Does alcohol cause high blood pressure?

    Excessive drinking creates a multitude of health risks. Also, some people are at risk for cardiovascular problems even when they consume alcohol in smaller amounts. Examples of these groups include:

    • People already affected by heart failure
    • People already affected by HBP
    • People with high triglyceride levels
    • People already affected by heartbeat irregularities
    • People with diabetes
    • People with a history of strokes

    Anyone that falls within the listed categories may find that typical rules of consuming alcohol in moderation may not apply. These categories of people will have a stronger adverse reaction to having alcohol in the body, and the side effects may be more severe than for regular people. One of the risks that people in these categories are more exposed to include alcoholic cardiomyopathy, discussed in the next section.

    Preventing High Blood Pressure

    Limiting alcohol consumption can also help to prevent high blood pressure.

    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. A drink is one 12 oz. beer, 4 oz. of wine, 1.5 oz. of 80-proof spirits or 1 oz. of 100-proof spirits.

    Moderate Drinking And Blood Pressure

    While some people suggest that moderate alcohol consumption improves heart health, several studies found that moderate drinking can cause high blood pressure and other heart problems. Moderate alcohol usage, defined as two or more drinks , substantially increases your risk of developing long-term high blood pressure, or chronic hypertension. However, when people go from drinking heavily to drinking in moderation, both their systolic and diastolic readings will decrease.

    Moderate alcohol consumption may be allowable with certain high blood pressure medications, but it is important to consult a doctor or pharmacist before doing so.

    Actions On The Endocrine System

    It is known that alcohol increases plasma renin activity., , As the increase in renin activity was suppressed by pretreatment with propranolol in our study, it seems to be mediated by the sympathetic nervous system. Alcohol also stimulated the release of adrenocorticotropic hormone, and increases in plasma cortisol and aldosterone were observed after drinking. It has been reported that dexamethasone inhibited the BP elevation and sympathetic activation after alcohol ingestion. We and others, however, have failed to observe significant changes in adrenocorticotropic hormone, cortisol or aldosterone.,

    Alcohol suppresses the release of vasopressin however, this change does not seem to mediate the acute depressor effect of alcohol., , Several depressor hormones and substances, such as atrial natriuretic peptide, prostaglandin E2, beta endorphin and cyclic GMP, did not change after alcohol ingestion. Although data relating alcohol intake to plasma atrial natriuretic peptide have been inconsistent, Djousse et al. observed a positive relationship after adjusting for several confounding factors.

    The level of plasma insulin increases after alcohol intake however, the change is less than that induced by an isocaloric control drink. It has been shown that a light-to-moderate intake of alcohol enhances insulin sensitivity and reduces the risk of type 2 diabetes mellitus. Alcohol therefore seems to have a beneficial effect on insulin and glucose metabolism.
