People Without Friends Have Worse Outcomes After Heart Attack

Without the support of friends and family, you’re less likely to emerge from a heart attack healthy.

A study in the Journal of the American Heart Association analyzed the responses of 3,432 heart attack patients on their levels of social support one month and then a year after a heart attack. One-fifth of them had low social support—meaning they felt that they didn’t have friends or family they could confide in or lean on for emotional or financial support—and during their recovery this group showed lower mental functioning, worse quality of life and more depressive symptoms. The effect affected men and women equally.

Encouraging social support isn’t usually seen as a top priority for heart attack recovery, but this is just one more piece of evidence that it should be: one study showed that within six months of having a heart attack, depression increased the risk of death from 3% to 17%.

“We shouldn’t just be concerning ourselves with pills and procedures,” said Harlan Krumholz, MD, the study’s senior author and director of the Center of Outcomes Research and Evaluation at Yale-New Haven Hospital, in a statement. “We have to pay attention to things like love and friendship and the context of people’s lives. It may be that these efforts to help people connect better with others, particularly after an illness, may have very powerful effects on their recovery and the quality of their lives afterwards.”
