Alcohol consumption can elevate an individual's risk of ische­mic stroke by 2.three occasions within the first hour after ingestion compared with threat throughout alcohol-free durations, no matter the type of liquor consumed.

Interviews with 209 males and 181 girls (average age: sixty eight years) conducted a median of three days put up-stroke revealed that 248 of the sufferers consumed wine, beer, and/or liquor within the prior yr, 104 within 24 hours of stroke onset, and 14 within one hour of stroke onset. The investigators calculated the relative threat of stroke within the hour after ingesting to be 2.three, which was similar for several types of alcoholic beverages and when the sample was restricted to individuals who were not uncovered to other potential stroke triggers on the time, equivalent to exercising vigorously or consuming a caffeinated beverage. The relative risk fell to 1.6 occasions greater within the second hour after drinking, returned to baseline throughout the subsequent three hours, and was 30% decrease than baseline after 24 hours.

Patients reported that they normally drank small quantities every time, and solely 13 said they usually drank greater than two servings.
