Every 4 years, the men received a mailed survey that asked questions about what they ate and drank. From the answers, the researchers counted how many alcoholic drinks each man drank per day. Every 2 years, the researchers sent a survey that asked whether the men had experienced a heart attack or stroke. The survey also asked about health problems that are known to increase a person’s risk for heart disease or stroke. The researchers then examined whether men with high blood pressure who also drank alcohol had fewer strokes than men who did not drink alcohol.
