Heart Attack Risk Linked to Work Stress

By: Sean Patterson - September 14, 2012

A new study published today in The Lancet shows that people with “highly demanding” job or those with “little freedom” are more likely to have a heart attack. Specifically, they are 23% more likely to have a heart attack than those with less stressful jobs.

The study, led by Professor Mika Kivimäki from the University College London department of epidemiology and public health, looked at 13 European national cohort studies from Belgium, Denmark, Finland, France Netherlands, Sweden, and the U.K. since 1985. The nearly 200,000 people who participated in the studies were given questionnaires that assessed their job demands, workload, time-pressure demands, and freedom to make decisions at work.

“The overall population attributable risk (PAR) for CHD events was around 3.4 per cent, suggesting that if the association were causal, then job strain would account for a notable proportion of coronary heart disease (CHD) events in working populations,” said Kivimäki. “As such, reducing workplace stress might decrease disease incidence. However, this strategy would have a much smaller effect than tackling standard risk factors such as smoking (PAR 36%) and physical inactivity (PAR 12%).”

The 23% higher risk of heart attack the new study finds stays consistent regardless of gender, age, or socioeconomic status. According to the University College London, previous studies linking work stress and heart disease have been limited, inconsistent, and put into question by shortcomings such as publication bias and reverse causation bias.

“The pooling of published and unpublished studies allowed us to investigate the association between CHD and exposure to job strain – defined by high work demands and low decision control – with greater precision than has been previously possible,” said Kivimäki. “Our findings indicate that job strain is associated with a small, but consistent, increased risk of experiencing a first CHD event such as a heart attack.”

    Study after study suggests that stress in any form is a contributing factor for heart disease. And worrying about stressful environments ironically adds to the stress already felt. So, what to do? The answer is to let go. Accept that the stress is a part of this job and expect things to be stressful. Practice saying, “It is what it is?” When you stop pushing against what-is, and instead go with the flow, all of of sudden you experience less stress. Nothing has changed in the circumstance, but everything has changed because your attitude has changed.

    There are several chapters on Stress and the heart in the Book: The Cure for Heart Disease (and Cancer Too) available on Amazon Kindle. I was in severe pain like a vise in my chest, at times all day long, and for 5 years. It was caused by the stress of being a busy trial lawywer. It was horrible. I have a several chapters on my entire experience with, Heart Stem Cell surgery, beta blockers and other useless prescription heart drugs in my book. I was in severe heart failure post infarct, for 5 long years. Later due to the things I did outlined in my book, especially using quality German made creatine pyruvate, I was able to finally recover from severe heart failure after a life threatening heart attack; this no thanks to the top doctors, stents, heart drugs, stem cell surgery, that were all completely useless. I was dying, really believe me. I used top quality creatine pyruvate made in Germany which was the only thing that saved my life. How this occurred is outlined in my 556 page 61 chapter book on Amazon Kindle titled: “The Cure for Heart Disease (and Cancer too)” by Stephen (Steve) Harte. I learned from Pax Beale after reading his biography. Pax felt so good using this same therapy as I did, after his doctor botched heart bypass and mortal heart failuire, that he then not only literally grew his heart back, but at age 63 became a world champion bodybuilder until he retired from competition at age 77. He is now 83 years old. This and the true peer reviewed scientific studies done in the US and worldwide are all outlined in my book which is priced next to nothing. Some of the studies actually compare pyruvate to commonly prescirbed heart drugs, and even stem cell surgery is compared in my book, and why this therapy worked and Stem Cell surgery did not; pyruvate is described as far superior. Nobody should die of a heart failure or from a heart attack any more. It is ridiculous. This really works, and requires only a reasonable determination. Regards, Stephen Harte, Author
