Initial autopsy results show severe coronary artery disease and evidence of a prior heart attack, a forensic pathologist from the hospital where Lay was taken said, during a news conference. Final autopsy results are pending.
Lay, 64, was due to be sentenced in October after being convicted of 10 counts of conspiracy and fraud in the Enron trial in May. He faced 25 to 40 years in prison. The fall of Enron became one of the biggest corporate scandals in U.S. history.
WebMD spoke with cardiologist Robert Myerburg, MD, about the role may play in heart attacks. Myerburg is a professor of medicine and physiology in the cardiology division of the University of Miami's medical school. Myerburg is not familiar with Lay's medical history.
Long-Term Stress & Heart Risks
Heart attacks and sudden death have been studied in relation to long-term stress and short-term (acute) stress, Myerburg tells WebMD.
He describes long-term stress as spanning "a number of years," such as a "stressful job or a stressful environment throughout one's life." Myerburg says "there are some data that says that stress over the long term can… contribute to risk of heart attack and sudden death."
He notes that long-term stress "may increase the probability" of those problems, "as opposed to being the cause." In other words, long-term stress may make heart attack or sudden death more likely but probably aren't the sole cause of such problems.
Sudden Stress & Heart Problems
Short-term stress unfolds in "minutes to hours," Myerburg says.
For instance, he notes that when Los Angeles experienced an earthquake in 1994, the L.A. area had three to four times the number of heart attacks and cardiac arrests than would have been expected on any given day.
But over the next two or three weeks, L.A.'s heart attacks and sudden deaths were lower than normal, Myerburg says. The theory, he explains, is that the earthquake caused a spike in heart attacks and sudden deaths among people who were on the verge of those problems.
"One of the biggest challenges is unrecognized ," Myerburg says. He points out that "in a third of sudden deaths, sudden death is the first clinical manifestation of heart disease." Those victims had had no previous warning their hearts weren't healthy.
Long-Term Stress & Heart RisksWhere Does Lay Fit?
If Lay had had a heart attack or died suddenly upon hearing his verdict, that scenario would have qualified as acute stress. If his legal case had lasted 10 years, that would fit long-term stress, Myerburg says.
But Lay's death doesn't quite fit either pattern. "It's hard to know where to put that," Myerburg says, calling Lay's legal ordeal an "intermediate" length of stress.
Enron entered bankruptcy in 2001. And Lay's criminal case lasted several years, but it was "not long enough to talk about development of heart disease," and "not long enough to develop atherosclerosis," Myerburg says.
Long-Term Stress & Heart RisksCoping With Stress
Getting a thorough checkup can help gauge your heart risk. And since stress is part of life, learning to cope with it may help.
Handling stress can be "rough," Myerburg says. Acute stresses often can't be avoided, and long-term ones may be hard to budge.
Myerburg says he often advises people to see psychiatrists or psychologists to help them cope with situational stresses. He calls long-term stress a "quality of life issue."
The following strategies may help you cope with stress:
- Eat and drink sensibly. Overindulging in alcohol and food adds to stress.
- Assert yourself. Learn to stand up for your rights and beliefs while respecting those of others.
- Stop smoking. Nicotine acts as a stimulant and brings on more stress symptoms.
- Exercise regularly. It's a stress-buster. Get your doctor's approval before starting a new fitness program.
- Relax every day. Techniques include meditation, deep breathing, biofeedback, and mental imagery.
- Take responsibility. Control what you can and leave behind what you cannot control.
- Cut causes of stress. Take good care of yourself, don't overload your schedule, set priorities, and skip hassles, such as bad, traffic when possible.
- Examine your values and live by them. Doing so may make you feel better, even under stress.
- Set realistic goals and expectations. It's OK -- and healthy -- to admit you cannot be 100% successful at everything all at once.
- Build your self-esteem. Feeling overwhelmed? Remind yourself of what you do well.
- Get enough rest. The time you spend resting should be long enough to relax your mind as well as your body.
