Insights
Body mass index (BMI) is not a useful predictor for patients with ischemic heart disease. This study found BMI did not correlate with prognosis despite associations with other cardiovascular risk factors.
Area of Science:
- Cardiology
- Public Health
- Clinical Research
Background:
- The prognostic value of Body Mass Index (BMI) in ischemic heart disease (IHD) patients remains unclear.
- Understanding BMI's role is crucial for risk stratification and patient management.
Purpose of the Study:
- To investigate the association between BMI and cardiovascular risk factors.
- To determine BMI's correlation with intra-hospital and 6-month mortality in IHD patients.
Main Methods:
- Prospective, multicenter study with 1063 IHD patients (25-75 years old).
- Data collected on demographics, anthropometrics, risk factors, and treatment.
- Univariate and multivariate analyses performed for prognostic assessment.
Main Results:
- Overweight and obesity (73.56% of patients) were linked to traditional risk factors (excluding smoking) and emergent factors.
- BMI showed no significant association with short-term or mid-term prognosis.
- No correlation found between BMI and patient mortality at 6 months.
Conclusions:
- Body Mass Index (BMI) is not a reliable anthropometric measure for predicting prognosis in patients following a first myocardial infarction.
- Clinical utility of BMI for post-MI risk assessment is limited.
Background And Objectives:
The value of body mass index in the prognosis of patients with ischemic heart disease is not well defined. The objective of our study was to determine the association of body mass index with classic and emergent cardiovascular risk factors and with intra-hospital and 6-months mortality.
Patients And Methods:
We conducted a prospective, multicenter study with a 6-months follow-up. We included 1063 patients between the ages of 25-75 years old who were consecutively admitted to the hospital within the first 24 hours of the onset of symptoms between years 2001 and 2003. We determined demographic and anthropometric variables, as well as classic and emergent factors of risk, clinical variables and the treatment administered. We carried out a univariate and multivariate analysis.
Results:
The percentage of patients with overweight or obesity in this population was 73.56%. Overweight and obesity were associated with classical risk factors, except for smoking, and emergent risk factors. Body mass index was not associated with short-or mid-term prognosis.
Conclusions:
Body mass index is not a useful anthropometric measure to determine the prognosis of patients after a first myocardial infarction.

Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...
