Risk Factors for Acute Myocardial Infarction in Latin America

FLFernando LaņasÁAÁlvaro AvezumLBLeonelo E. Bautista

Key Result

The Framingham cardiovascular risk score was not independently associated with a non-dipper blood pressure pattern after adjusting for blood pressure levels, whereas age (OR 1.06) and obesity (OR 1.82) were independent predictors.

Structured PICO

What are the primary modifiable risk factors associated with first acute myocardial infarction in Latin America?

P
Population
308 participants from the CHICAMOCHA cohort (269 with probable hypertension and 39 controls) evaluated with ambulatory blood pressure monitoring after a median 12-year follow-up.
E
Exposure
Presence of cardiovascular risk factors (psychosocial stress, hypertension, diabetes mellitus, smoking, increased waist-to-hip ratio, increased apolipoprotein B to A-1 ratio)
C
Comparator
Absence of these risk factors or lower tertiles
O
Outcome
First acute myocardial infarctionhard clinical

Modifiable risk factors, particularly abdominal obesity, abnormal lipids, and smoking, account for 88% of the population-attributable risk for acute myocardial infarction in Latin America.

Main Result

Absolute Event Rate: 74% vs 57%

p-value: p=0.039

Abstract

BACKGROUND: Current knowledge of the impact of cardiovascular risk factors in Latin America is limited. METHODS AND RESULTS: As part of the INTERHEART study, 1237 cases of first acute myocardial infarction and 1888 age-, sex-, and center-matched controls were enrolled from Argentina, Brazil, Colombia, Chile, Guatemala, and Mexico. History of smoking, hypertension, diabetes mellitus, diet, physical activity, alcohol consumption, psychosocial factors, anthropometry, and blood pressure were recorded. Nonfasting blood samples were analyzed for apolipoproteins A-1 and B-100. Logistic regression was used to estimate multivariate adjusted odds ratios (ORs) and their 95% confidence intervals (CIs). Persistent psychosocial stress (OR, 2.81; 95% CI, 2.07 to 3.82), history of hypertension (OR, 2.81; 95% CI, 2.39 to 3.31), diabetes mellitus (OR, 2.59; 95% CI, 2.09 to 3.22), current smoking (OR, 2.31; 95% CI, 1.97 to 2.71), increased waist-to-hip ratio (OR for first versus third tertile, 2.49; 95% CI, 1.97 to 3.14), and increased ratio of apolipoprotein B to A-1 (OR for first versus third tertile, 2.31; 95% CI, 1.83 to 2.94) were associated with higher risk of acute myocardial infarction. Daily consumption of fruits or vegetables (OR, 0.63; 95% CI, 0.51 to 0.78) and regular exercise (OR, 0.67; 95% CI, 0.55 to 0.82) reduced the risk of acute myocardial infarction. Abdominal obesity, abnormal lipids, and smoking were associated with high population-attributable risks of 48.5%, 40.8%, and 38.4%, respectively. Collectively, these risk factors accounted for 88% of the population-attributable risk. CONCLUSIONS: Interventions aimed at decreasing behavioral risk factors, lowering blood pressure, and modifying lipids could have a large impact on the risk of acute myocardial infarction among Latin Americans.

Laņas et al. (2007) conducted a cross-sectional in Hypertension and Cardiovascular Risk (n=308). Framingham cardiovascular risk score (EFRCV) vs. Lower risk tertiles was evaluated on Non-dipper blood pressure pattern on ambulatory monitoring (p=0.039). The Framingham cardiovascular risk score was not independently associated with a non-dipper blood pressure pattern after adjusting for blood pressure levels, whereas age (OR 1.06) and obesity (OR 1.82) were independent predictors.
