An acute myocardial infarction, also known as a heart attack, occurs when the blood supply to the heart is severely reduced or completely blocked. During a heart attack, heart muscle cells do not receive enough oxygen and begin to die. The more time that passes without treatment to restore blood flow, the greater the damage to the heart.
Research has identified several factors that increase the risk of a heart attack including hypertension, low high-density lipoprotein (HDL) cholesterol, high low-density lipoprotein (LDL) cholesterol, high triglycerides, poor diet, obesity, and having a family history of heart disease. Research has also suggested a relationship between outdoor air pollution and an increased risk of heart attack and other forms of heart disease. A number of studies, usually focused on the elderly, have reported associations between air pollution and hospitalizations for heart attacks and other forms of heart disease. In addition, exposure to secondhand tobacco smoke, a type of air pollution, is linked to an increased risk of coronary heart disease.

Tracking Heart Attacks in Louisiana
These measures were developed following the Centers for Disease Control and Prevention (CDC) Standards for Nationally Consistent Data and Measures (NCDMs) within the Environmental Public Health Tracking Network. The purpose of NCDMs is to ensure compatibility and comparability of data and measures useful for understanding the impact of our environment on our health. The Health Data Explorer contains data on the following measures for hospitalizations with a primary diagnosis of heart attack among persons 35 and over:
