Insights
Acute myocardial infarction (AMI) mortality is higher in patients over 65 and with anterior AMI. Survival rates improve after the initial critical period in the intensive care unit (ICU).
Area of Science:
- Cardiology
- Public Health
- Epidemiology
Context:
- Acute myocardial infarction (AMI) is a leading cause of death globally, particularly in industrialized nations.
- While more common in men, AMI is more fatal in women, with mortality increasing after age 50.
- Understanding factors influencing AMI mortality is crucial for improving patient outcomes.
Purpose:
- To analyze the survival rates of patients diagnosed with AMI in the intensive care unit (ICU) at Hospital of Cabueñes.
- To investigate the relationship between mortality, site, and type of AMI.
- To identify demographic and clinical factors associated with AMI mortality.
Summary:
- A retrospective study of 253 AMI patients in 2001 revealed that age over 65 and anterior AMI site significantly increase mortality.
- No significant differences in mortality were observed based on gender or electrocardiographic type of AMI.
- Mortality rates were highest in the initial days post-infarction, decreasing progressively during follow-up.
Impact:
- Age and anterior AMI site are key predictors of mortality, highlighting the need for targeted interventions.
- Mortality risk is elevated during ICU stay, emphasizing the importance of intensive monitoring and care.
- Findings contribute to a better understanding of AMI prognosis and inform clinical management strategies.
Introduction:
Acute myocardial infarction (AMI) is caused by total occlusion of the coronary artery lumen. Ischemic heart disease is the main cause of death in industrialized countries, it being more frequent in men, although more fatal in women. Its mortality rate increases after fifty years of age.
Objectives:
To perform a survival analysis of the patients with AMI diagnosis in the ICU of the Hospital of Cabueñes; to learn the relationship existing between the mortality rate, site and types of AMI. Patients and method. Retrospective descriptive study of 253 patients diagnosed of AMI in the year 2001 by review of clinical records and telephone follow-up. The variables used were age, gender, site and type of AMI. The SPSS statistical program was used to obtain the results.
Results:
Age above 65 years and anterior site of AMI increase mortality. No significant differences are observed in regards to gender and electrocardiographic type. Post-infarction mortality is very high in the first days, followed by a progressive decrease in the follow-up.
Conclusion:
Mortality is not conditioned by the different types of AMI and it is seen to be greater during the stay in the ICU.
