Abstract
Background: Prevention of recurrent acute myocardial infarction achieved by controlling serum lipid levels at optimal levels, the patients’ perceptions of their illnesses and performing good behaviors including food consumption, exercise, adherence to medication, and smoking cessations.
Objective: This predictive correlation research aimed at examining the serum lipid levels among patients with recurrent acute myocardial infarctions and at studying the predictive power of five factors to affect the serum lipid levels among patients with recurrent acute myocardial infarctions.
Method: The subjects consisted of 91 individuals, who were patients with recurrent acute myocardial infarctions and who had received treatment at hospitals in the Eastern Region.
The subjects were selected by using simple random sampling. Data collection was conducted between January 2018 and January 2019. The research instruments consisted of the following: 1) a demographic questionnaire, 2) a medical records form, 3) an illness perceptions questionnaire, 4) an eating behaviors questionnaire, 5) an exercise behaviors questionnaire, 6) a medication adherence questionnaire, and 7) a smoking behavior questionnaire. Descriptive statistics and multiple linear regression analysis were employed to analyze the data.
Results: The mean serum lipid levels of the patients with recurrent acute myocardial infarctions had shown the total cholesterol levels to be normal (M = 173.4, SD = 46.9),
while the LDL cholesterol levels had been higher than the target (M = 109.3, SD = 41.8). Both the HDL cholesterol levels (M = 43.1, SD = 12.0) and the Triglyceride levels (M = 148.4, SD = 60.9) had been normal. The behavioral factor of medication adherence could predict the serum lipid levels of patients with recurrent acute myocardial infarctions in that the total cholesterol and LDL cholesterol had been statistically significant (β = -4.20, p = 0.02 and β = -5.65, p < 0.001). All factors can predict the LDL cholesterol at 10% (Adjust R2= 0.10, p = 0.01).
Conclusion: The mean LDL cholesterol of patients with recurrent acute myocardial infarctions had been higher than the normal values. This study suggests that nurses should be promoting medication adherence, which could determine the LDL cholesterol levels of patients with acute myocardial infarctions and could reduce recurrences.
