Inpatient Hospitalizations due to Heart Attack (Acute Myocardial Infarction) by County, New Jersey, 2022
Why Is This Important?
A heart attack (acute myocardial infarction) occurs because of coronary heart disease, which is the narrowing of the coronary arteries that supply blood to the heart muscle. When the blood supply to part of the heart is interrupted or blocked, the heart muscle is deprived of oxygen. This can result in chest pain, shortness of breath, nausea, palpitations, sweating and anxiety. Risk factors for coronary heart disease include: high levels of low-density lipoprotein ("bad cholesterol") and triglycerides in the blood; high blood pressure; diabetes; a diet high in saturated fat; physical inactivity; obesity; and excessive alcohol use. Recent research has shown that fine particulate matter air pollution can increase the risk of heart attacks.
Definition
Inpatient hospitalizations due to acute myocardial infarction (heart attack) among residents aged 35 years and over. Primary diagnosis of acute myocardial infarction, defined by ICD-9 codes 410.00-410.92 for January 2000 through September 2015, and ICD-10 codes I21 and I22 for the last quarter of 2015 and beyond.

How the Measure is Calculated
Numerator:
Number of inpatient hospitalizations with a primary diagnosis of acute myocardial infarction occurring among residents aged 35 years and olderDenominator:
Estimated number of persons aged 35 years and older in the population
Data Issues
'''Overall Discharge Volume in 2020: ''' Hospital claim volume for the 2020 calendar year was markedly lower (19.9%) than for 2019, mostly due to the COVID-19 pandemic. This reduction was seen in both inpatient discharges (8.2% lower claim volume than 2019) and emergency department visits (27.3% lower claim volume than 2019). This was likely the result of hospital care being redirected to address the care for COVID-19 patients while elective surgeries and other outpatient care services were being postponed. '''ICD Coding between 2015 and 2016: ''' The nationwide switch from ICD-9-CM to ICD-10-CM hospital diagnosis coding on October 1, 2015 disrupted trends for some diseases and conditions. Interpret trend data in this report with caution. Also note that New Jersey's data for October through December, 2015 was recoded to ICD-9-CM so that entire year of data was coded the same way.Related Health Objectives and Indicators
