Milestone One Health Question Selection

Myocardial infarctions (MIs), another name for heart attacks, are common in people 60 and older. Blockage in a coronary artery reduces blood flow to the heart, leading to cardiac arrest. Plaque, which is made up of cholesterol, fat, and other chemicals, builds up over time in the coronary arteries and causes their obstruction (Gerstman, 2015). This research aims to determine whether or not heart attack victims' hospital stays are affected by their gender. The data used in this report was collected from the Worcester Heart Attack Study (WHAS100) by Hosmer et al. (2008). The research question is, "Does gender influence the length of stay (LOS) of myocardial infarction patients (MI)?" Acute care hospitalized patients with myocardial infarction will have their length of stay (LOS) and gender analyzed using the Stat Crunch software (Pearson Education, 2014) to see whether or not these factors have a significant effect on the patient's outcomes (MI). The test will be administered separately to male and female patients using a two-sample t-test.
