Diet may affect risk of sudden cardiac death

  • A study found that a diet high in added fats, fried foods, processed meats, and sugary drinks was associated with a greater risk of sudden cardiac death, while a Mediterranean diet was associated with a lower risk.
  • The findings provide evidence that adopting a healthier diet may decrease the risk of sudden cardiac death.

Diet is known to influence heart health. Experts recommend a diet low in sodium and saturated fat to reduce the risk of heart disease. A heart-healthy diet also includes plenty of vegetables, fruits, and whole grains. Research shows that the Mediterranean diet—full of fruits, vegetables, fish, cereals, and legumes, with little meat and dairy—may reduce the risk of heart disease.

Few studies have examined the relationship between overall diet and sudden cardiac death, a common cause of death in the United States. In sudden cardiac death, the heart abruptly stops beating, leading to death within an hour of symptoms. Small studies have suggested that the Mediterranean diet may lower the risk of sudden cardiac death.

A team led by Dr. James M. Shikany of the University of Alabama at Birmingham examined whether dietary patterns are associated with the risk of sudden cardiac death. The study was funded by NIH’s National Institute of Neurological Disorders and Stroke (NINDS), National Institute on Aging (NIA), and National Heart, Lung, and Blood Institute (NHLBI). Results were published in the Journal of the American Heart Association on July 6, 2021.

Physical Activity Decreases Sudden Cardiac Death Risk in Unfit Men

Dr Laukkanen said: “Sudden cardiac death (SCD) accounts for approximately 50% of deaths from coronary heart disease. SCD typically occurs shortly after the onset of symptoms, leaving little time for effective medical interventions, and most cases occur outside hospital with few or no early warning signs. Finding ways to identify individuals at elevated risk of SCD would allow early interventions on risk factors to be implemented.”

The current study investigated the impact of high leisure-time physical activity (LTPA) combined with cardiorespiratory fitness (CRF) on risk of SCD. It included 2,656 randomly selected men aged 42 to 60 years from the Kuopio Ischemic Heart Disease Risk Factor Study, a Finnish study of risk predictors for cardiovascular outcomes and SCD in the general population. Baseline cycle exercise test and risk factor assessment were performed in 1984-89. SCD was defined as death with cardiac origin within 24 hours after onset of symptoms.

Why You Shouldn’t Run a Marathon

I  have stated previously in these pages that I while I respect and admire the exercise of running, I have even considered taking it up to get more weight-bearing exercise, I think that on-balance marathons damage the body and should be avoided. Since October is the beginning of marathon season, I wanted to put this out.

Dr. Mercola
says, “Several recent studies have indicated that conventional cardio, especially endurance exercises such as marathon running can pose significant risks to your heart. It can result in acute volume overload, inflammation, thickening and stiffening of the heart muscle and arteries, arterial calcification, arrhythmias, and potentially sudden cardiac arrest and stroke—the very things you’re trying to avoid by exercising.
