Heart disease is the number one cause of death in the US, around 24% of deaths every year. Strokes are fifth most common cause of death at 5%, dementia sixth most common at 3.6%, data here from 2014. Accidents have beaten strokes out for fourth place because of "unintentional overdose" deaths.
I did a physical on a man recently, who said what was the best thing he could do for his health?
"Reduce or better yet quit alcohol." is my reply. Even though he's within "current guidelines". I showed him the first of these studies.
Two recent studies get my attention for the relationship between the heart and the brain and alcohol.
In this study: http://www.onlinejacc.org/content/64/3/281, 79,019 Swedish men and women were followed after completing a questionnaire about alcohol consumption.
They were followed from 1998 to 2009 and 7,245 cases of atrial fibrillation were identified. The relative risk for atrial fibrillation was alcohol dose dependent: that is, the people who did not drink had a relative risk of atrial fibrillation set at 1.0. At 1-6 drinks per week the risk was 1.07, at 7-14 per week the risk was 1.07, at 14-21 drinks per week 1.14 and at >21 drinks per week 1.39. They also break it down by number of drinks per day. So why do we care about atrial fibrillation? "Atrial fibrillation (AF)/atrial flutter (AFL), the most common cardiac arrhythmia, is accompanied with a 4- to 5-fold increased risk for stroke, tripling of the risk for heart failure, doubling of the risk for dementia, and 40% to 90% increase in the risk for all-cause mortality."
Atrial fibrillation, stroke, congestive heart failure, dementia and 40-90% increase in all-cause mortality. Want to protect your brain and live longer? Quit alcohol.
Well, that instantly decreased my enthusiasm for alcohol, now down to one drink per week if that.
Here is a second study: https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(18)30134-X/fulltext?code=lancet-site
In the 599 912 current drinkers included in the analysis, we recorded 40 310 deaths and 39 018 incident cardiovascular disease events during 5·4 million person-years of follow-up. For all-cause mortality, we recorded a positive and curvilinear association with the level of alcohol consumption, with the minimum mortality risk around or below 100 g per week. Alcohol consumption was roughly linearly associated with a higher risk of stroke (HR per 100 g per week higher consumption 1·14, 95% CI, 1·10–1·17), coronary disease excluding myocardial infarction (1·06, 1·00–1·11), heart failure (1·09, 1·03–1·15), fatal hypertensive disease (1·24, 1·15–1·33); and fatal aortic aneurysm (1·15, 1·03–1·28). By contrast, increased alcohol consumption was log-linearly associated with a lower risk of myocardial infarction (HR 0·94, 0·91–0·97). In comparison to those who reported drinking >0–≤100 g per week, those who reported drinking >100–≤200 g per week, >200–≤350 g per week, or >350 g per week had lower life expectancy at age 40 years of approximately 6 months, 1–2 years, or 4–5 years, respectively."
Ok, over half a million people followed, 40K+ deaths, 39K+ heart events (heart attack, atrial fibrillation, new congestive heart failure, etc), that's a pretty impressive study.
A 5% 12 ounce beer is 14 grams of alcohol. Here: https://www.niaaa.nih.gov/alcohol-health/overview-alcohol-consumption/what-standard-drink. Our local brewery and pourhouse usually serve pints, 16 oz, and the range is from 5% to over 9% alcohol. Two 9% pints is how many standard drinks? You do the math. Currently the recommendations in the US are no more than seven drinks per week for women (98 grams) and fourteen for men (196 grams) per week, no saving it up for the weekend, no bingeing. The UK stops at 98 grams for both men and women. The rest of Europe goes higher.
Heart and brain, how I love you! I like my brain and don't want to pickle it. I think I'll choose heart and brain over alcohol, long term over short term, health over escapism.
Have a great week!
