A new study identifying 56 non-clinical risk factors associated with sudden cardiac arrest (SCA), spanning lifestyle, physical measures, psychosocial factors, socioeconomic status, and the local environment, offers compelling evidence that improving these unfavorable profiles could prevent up to 63% of SCA cases. The article appearing in the Canadian Journal of Cardiology, published by Elsevier, provides new insights into how lifestyle and environmental factors can contribute to SCA prevention.

For almost 60 years, measuring cholesterol levels in the blood has been the best way to identify individuals at high risk of cardiovascular disease.
