The Relationship between Wine Consumption and Cardiac Disease
The number of strokes is actually higher than the numbers suggest because a large percentage of strokes are “silent,” meaning that they go unnoticed by person.
The American Heart Association published an article written by Dr. Larry Goldstein on alcohol consumption and risk of stroke. Although not a study in itself, Goldstein evaluated 35 cohort studies between 1966 and 2002 that examined the relationship between alcohol and stroke.
Goldstein found that when compared to non-drinkers, moderate drinkers have significantly lower risk of suffering an ischemic stroke. However, when the number of drinks per day begins to rise above three, the risk of ischemic stroke rises above non-drinkers. Represented graphically, the curve would be “U-shaped,” with the risk of stroke decreasing from 0 – 1 drinks per day, then increasing proportionally after 2 drinks per day.
This information was backed up by a study published in the Journal of the American Medical Association (JAMA) by Dr. Sacco et. al. in The Protective Effect of Moderate Alcohol Consumption on Ischemic Stroke, Dr. Sacco et.al. found that moderate alcohol consumption (2 drinks per day or less) had a statistically significant cardio protective effect on ischemic stroke.
This study was performed in New York over a four year period. The results of the study were corrected for familial cardiac disease, diabetes, smoking, education, body mass index and hypertension. The conclusion of this study indicates that moderate alcohol consumption decreases the risk of stroke.
