Old age, diabetes, recurrent myocardial infarction, and low left ventricular ejection fraction were identified as key poor prognostic factors, which are exacerbated by patients' lack of disease awareness and inadequate self-care.
This study highlights the importance of continuous monitoring and education on self-care and lifestyle modification to prevent poor prognosis, such as heart failure, in post-MI patients.
BACKGROUND: As patients with myocardial infarction (MI) survive for a long time after acute treatment, it is necessary to pay attention to the prevention of poor prognosis such as heart failure (HF). To identify the influencing factors of adverse clinical outcomes through a review of prospective cohort studies of post-MI patients, and to draw prognostic implications through in-depth interviews with post-MI patients who progressed to HF and clinical experts. METHODS: A mixed-method design was used that combined a scoping review of 21 prospective cohort studies, in-depth interviews with Korean post-MI patients with HF, and focus group interviews with cardiologists and nurses. RESULTS: A literature review showed that old age, diabetes, high Killip class, low left ventricular ejection fraction, recurrent MI, comorbidity of chronic disease and current smoking, and low socioeconomic status were identified as influencing factors of poor prognosis. Through interviews with post-MI patients, these influencing factors identified in the literature as well as a lack of disease awareness and lack of self-care were confirmed. Experts emphasized the importance of maintaining a healthy lifestyle after acute treatment with the recognition that it is a chronic disease that must go together for a lifetime. CONCLUSION: This study confirmed the factors influencing poor prognosis after MI and the educational needs of post-MI patients with transition to HF. Healthcare providers should continue to monitor the risk group, which is expected to have a poor prognosis, along with education emphasizing the importance of self-care such as medication and lifestyle modification.
Hwang et al. (Tue,) conducted a other in Myocardial infarction (post-MI) transitioning to heart failure (n=23). Risk factors for poor prognosis (e.g., old age, diabetes, recurrent MI, lack of self-care) was evaluated on Influencing factors of poor prognosis after MI. Old age, diabetes, recurrent myocardial infarction, and low left ventricular ejection fraction were identified as key poor prognostic factors, which are exacerbated by patients' lack of disease awareness and inadequate self-care.
