One-Year Death Rates for Heart Disease, Diabetes, and Stroke Decline
Chronic diseases – including diabetes, high blood pressure, and heart disease – are costly yet largely preventable. Chronic illnesses contribute to a substantial proportion of the nation’s health-related costs and remain the leading causes of illness, disability, and death in America.[1] This indicator reports prevalence and death data for heart disease, diabetes, and high blood pressure/stroke. Also tracked are hospitalizations due to heart failure and hypertension.
TREND
Heart Disease
The percentage of county residents ever diagnosed with heart disease decreased from 8.3% in 2022 to 5.5% in 2023. In 2023, San Bernardino County’s death rate due to heart disease was 164.3 deaths per 100,000 residents. This marks a 9.5% increase since 2014 when the death rate was 144.2 per 100,000 residents, and a one-year decrease of 8.2% since 2022 when the death rate was 179.0 per 100,000.

Diabetes
The long-term trend is toward increasing diabetes diagnoses and deaths. In 2023, 17.0% of adults in San Bernardino County had been diagnosed with diabetes in their lifetimes. This is an increase from 2022, when diabetes prevalence was 12.6%, and an increase from 2014, when 12.5% of adults in the county had a diabetes diagnosis. Deaths due to diabetes increased from 27.4 deaths per 100,000 residents in 2014 to 34.0 deaths per 100,000 residents in 2023. There has been, however, a decrease in deaths due to diabetes per 100,000 residents every year since 2020.

Blood Pressure / Stroke[2]
In 2023, 30.2% of adults in San Bernardino County had high blood pressure, which is a higher proportion than in 2022 when 28.8% of adults had high blood pressure.

The long-term trend, however, is upward, with a 24% increase in deaths per 100,000 due to strokes since 2014.

Hospitalizations Rates Due to Heart Failure and Hypertension Higher than California
In 2022, the hospitalization rates for heart failure (a chronic condition where the heart does not pump blood efficiently) and hypertension (high blood pressure) in San Bernardino County were 402.2 and 62.9 per 100,000 residents (risk adjusted), respectively. These are higher than the California hospitalization rate of 380.7 and 51.3 per 100,000 residents for heart failure and hypertension, respectively. The five-year trend for heart failure hospitalizations is down 5%, while the hospitalization rates for hypertension is up 18%.
