Out-of-hospital cardiac death (OHCD) is a major clinical and public health problem. Many OHCDs are sudden unexpected cardiac deaths, particularly in younger adults.
United states (US) vital statistics mortality data from 1999 to 2010 were analyzed. OHCD is defined as deaths occurring out of the hospital or in the emergency room or as “dead on arrival” with an underlying cause of death reported as a cardiac disease (ICD10 code 100 to 109, 113, 120 to 151, or Q20 to Q24). Death rates were calculated for residents of the US aged 35 years and standardized to the 2000 US population.
Of 593 528 cardiac deaths among adults aged 35 years in 2010, 425 236 (71.6%) were defined as OHCDs. Overall, OHCDs accounted for 77.6% of cardiac death for ages 35 to 44 years; 77.8% for 45 to 54 years; 72.8% for 55 to 64 years; 65.4% for 65 to 74 years; 66.5% for 75 to 84 years; 75.8% for ≥85 years. Of all OHCDs in 2010, coronary artery disease was the underlying cause on 65.2% of death certificate. Death rates for OHCD increased with age and were higher in men than women; the gender difference narrowed however with increasing age. African Americans had higher death rates for OHCD than white, American Indian/Alaska Native, or Asian/Pacific Islander population. From 1999 to 2010, OHCD, as the proportion of all cardiac deaths, increased 11.7%, and age-adjusted OHCD rates declined 16.4% in men and 24.7% in women. During the same time, age-specific death rates for OHCD increased 2% among women aged 45 to 54 years.
OHCD remains an important public health problem in the US. National effort should target increased awareness of symptoms and signs of heart attack and cardiac arrest and should attempt to increase the numbers of bystanders trained and willing to initiate the “chain of survival”.
