Health Indicator Report of Heart Attack: Hospitalizations

Heart attacks are associated with coronary heart disease, the number one killer of Utahns. There are several types of risk factors associated with heart attacks. Some of these include family history, high blood pressure, tobacco use, high cholesterol, physical inactivity, diabetes, obesity, and exposures to environmental contaminants. Recent studies have shown significant relationships between air pollutants and increased risk of heart attack or other forms of coronary heart disease. Particulate matter (PM,,2.5,,) has shown to be associated with increased risk in sensitive sub-populations such as the elderly, patients with preexisting heart disease, and those who are survivors of a heart attack.

Heart Attack Hospitalizations: Age-adjusted Rates Among Persons 35 and Over by Year, Utah, 2000-2013


This data is provided to the Environmental Epidemiology Program (EEP) within the Utah Department of Health (UDOH). This data is converted from being discharge data (which is present on the queryable data sets) to data by admission date. Heart attacks were defined with a primary diagnosis of 410-410.92 according to the International Classification of Diseases (ICD-9) codes. The U.S. is currently using the 10th revision (ICD-10) to code causes of death. The 9th revision (ICD-9) is still used for hospital and emergency department visits.   [[br]] [[br]] Age-adjusted rates were calculated using county specific crude rates for ages 35 and older with 2000 standard U.S. population weights for age 35 and older.

  • Population Estimates: National Center for Health Statistics (NCHS) through a collaborative agreement with the U.S. Census Bureau, IBIS Version 2013

Data Interpretation Issues

Hospitalization data for heart attacks do not include individuals who do not receive medical care or who are not hospitalized. This includes those who die in emergency rooms, in nursing homes, or at home, and those treated in outpatient settings. Also, the measures are based upon events, not individuals. Therefore, if an individual is admitted multiple times, each admission will be counted separately. This could overestimate the true prevalence of heart attacks. NOTE: This data is based on the date of admission, not the date of discharge (such as what is used in the IBIS query). Therefore data will differ between IBIS query and the values reported here.


A heart attack, also known as a myocardial infarction, occurs when a coronary artery is completely blocked by a clot resulting in lack of blood flow to the heart and death of part of the heart muscle. These heart attack hospitalizations are based on the date of admission (using the same discharge dataset, but converting to date of admission).


This indicator contains the following ways of characterizing hospitalizations:[[br]] # Number of hospitalizations for a primary diagnosis of heart attack. # Rate of hospitalization among persons 35 and over by age group. # Age-adjusted rate of hospitalization for persons 35 and over. # Average daily number of hospitalizations by month. # Maximum daily number of hospitalizations by month. # Minimum daily number of hospitalizations by month.


When applicable, population was obtained from the IBIS query for appropriate years by 5-year age groups for persons 35 and above.

What Is Being Done?

Over the past several years, the Utah Bureau of Emergency Medical Services and Preparedness (BEMS) has enlisted the expertise of hospital cardiac care experts, cardiologists, emergency physicians, other emergency medical providers, the Utah Hospital Association, and the American Heart Association to develop a system to speed the recognition and treatment of heart attack patients. The focus of this system is to integrate emergency medical services (EMS) and hospitals to get patients with a certain type of heart attack, called a ST segment elevation myocardial infarction (STEMI), to the best hospital that is able to treat them in the shortest possible time. The Utah STEMI system involves a multi-faceted approach to heart attack victims. EMS agencies, utilizing field electrocardiograms, identify STEMI patients and alert hospital emergency departments of the patient's condition and time of arrival. The field ECG is transmitted to the receiving hospital directly from the patient's location, allowing immediate review by the hospital physicians. This allows them to assist in the field care of the patient, as well as to activate their hospital STEMI team to ready the cath lab. As a result of this coordinated response, precious minutes are saved.
