- Experiencing a substantial drop in income may raise the risk of having a heart attack or stroke years later, a recent study suggests.
"While chronic stress raises blood pressure and probably causes inflammation that affects blood vessels, I tend to believe the social and economic effects are more important," Havranek said by email. And, for the lucky ones whose fortunes improved dramatically, average household income rose from US$26,099 to US$53,347. These people with large income gains were 14per cent less likely to have a heart attack, stroke, or heart failure than their counterparts with steady earnings.
