New research shows that having shingles may increase the risk of having a stroke years later.
Researchers at the University College London, UK, found that people ages 18 to 40 who had singles were more likely to have a heart attack, stroke, or transient ischemic attack (TIA), years later than those who did not have shingles. People over 40 who had shingles were more likely to have a heart attack or TIA, but not a stroke.
The study involved 106,600 people who had shingles and 213,200 people who did not. Researchers used a UK database to review patients’ records for about six years after they were diagnosed with shingles and for as long as 24 years for some participants. People under 40 years old were 74 percent more likely to have a stroke if they had had shingles.
