About Heart Attack Hospitalizations Data
Overview
This site provides data of the number and rate of heart attack hospitalizations in New York State. Heart attack hospitalization data are presented by age groups, sex, month of year, and total population in selected three year intervals (ex. 2000-2002, 2001-2003, etc...). The table below shows key information about heart attack hospitalization data.

Interpreting Data
These data show only people who have been hospitalized for heart attack and would not include those not admitted to the hospital (e.g, people treated in nursing homes, outpatient settings, at home or emergency rooms).
Differences in heart attack hospitalization rates could reflect differences in diagnostic techniques, coding of heart attack, as well as differences that could affect the likelihood of people being hospitalized for heart attack, such as access to medical care, sociodemographic characteristics, individual behaviors and exposures to environmental risk factors.
Data show the number of heart attack hospitalizations rather than the number of patients who were admitted or seen for heart attacks. For example, if a person was hospitalized twice they would be counted twice.
View by County
View by County shows maps and tables of the number of heart attack hospitalizations and the heart attack age-adjusted hospitalization rate for New York State for a selected three year time period.
Heart Attack Age-Adjusted Hospitalizations
Users can compare heart attack hospitalizations for those aged 35 and above per 10,000 residents. The maps show average heart attack age-adjusted hospitalization rates for the selected three year period. Users can compare heart attack hospitalizations across counties in the following regions: New York State (whole state), New York City, New York State Excluding New York City. Users can see more clearly the differences in heart attack hospitalization rates between the remaining New York State counties when New York City counties are removed from the display.
View by Age, Age and Sex, and Month
View by Age, Age and Sex, and Month shows charts and tables of statewide heart attack hospitalizations by demographic characteristics of age, age and sex, and time (month) of year. Heart attack hospitalization rates and counts are provided.
Heart Attack Hospitalizations by Age Group, New York State
Users can evaluate if there are certain age groups with higher heart attack hospitalization rates. The chart shows six years of heart attack hospitalization rates per 10,000 by age group and year; the data table also includes the number of heart attack hospitalizations. The age groups are: 0-34 years, 35-44 years, 45-54 years, 55-64 years, 65-74 years, 75-84 years, and 85+ years.
Heart Attack Hospitalizations by Age Group and Sex, New York State
Users can view heart attack hospitalization rates for males and females in certain age groups. The chart shows heart attack hospitalization rates per 10,000 of males and females in the age groups of 0-34 years, 35-44 years, 45-54 years, 55-64 years, 65-74 years, and 75-84 years, and 85+ years; the data table also shows the number of heart attack hospitalizations in those categories.
Daily Average Heart Attack Hospitalizations by Month, New York State
Users can see how heart attack hospitalizations vary by time of year. The chart shows the daily average number of heart attack hospitalizations by the month averaged over a selected three year time period; the data table includes annual data.
About Unstable Rates
When a heart attack hospitalization rates is based on small numbers, an increase or decrease of just 1 or 2 heart attack hospitalizations from year to year can cause the heart attack hospitalization rate to change dramatically; such a rate is likely to be unstable. Unstable heart attack hospitalization rates are marked with the symbol 
in data tables when the rate is based on fewer than 12 cases. These rates should be interpreted with caution.
Technical Notes
- Heart attack hospitalization data for New York State was generated from the Statewide Planning and Research Cooperative System (SPARCS) database .
- Heart attack ED visit or hospitalization years and months are based on hospital admission date.
- In October 2015, reporting of diagnosis codes in the hospitalization and ED visit datasets switched from International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) coding to International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) coding. This may result in apparent changes in trends between 2015 and 2016 that are due solely to the switch from ICD-9-CM to ICD-10-CM.
- For Hospitalizations that had a hospital admission date before October 1, 2015: A heart attack hospitalization is defined as having a principal diagnosis with an International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) code of 410.
- For Hospitalizations that had a hospital admission date on or after October 1, 2015: A heart attack hospitalization is defined as having a principal diagnosis with an International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) code that starts with I21 (12 codes) or I22 (5 codes).
- Population estimates used for calculating heart attack hospitalization rates were taken from the U.S. Census Bureau. State hospitalization rates are based on State Characteristics Population Estimates File, available at Population Estimates Data Sets. New York State county level hospitalization rates are based on County Characteristics Resident Population Estimates File, available at Population Estimates Data Sets.
- Heart attack hospitalization rates and age-adjusted rates were calculated per 10,000 residents. The age-adjusted rates were calculated using the 2000 U.S. Standard Population.
