Key result
Traditional cardiovascular risk factors, including diabetes (OR 5.27), hypertension (OR 5.24), kidney disease (OR 5.20), and obesity (OR 2.87), significantly increased the odds of myocardial infarction in older adults treated in primary care.
Why the study?
The prevalence of myocardial infarction and its association with cardiovascular risk factors in older adults in Primary Care required investigation.
Cross-Sectional (n=1,322)
Yes
Odds Ratio: 5.27 (95% CI 3.21–8.6)
Absolute Event Rate: 17.2% vs 3.3%
p-value: p=<0.001
Traditional cardiovascular risk factors, particularly diabetes, hypertension, and chronic kidney disease, are highly prevalent and strongly associated with increased odds of myocardial infarction among older adults in primary care.
Supports risk factor screening in northern Brazilian primary care elders; leaves open causal direction and generalizability pending longitudinal data.
OBJECTIVES: to investigate the prevalence of myocardial infarction and its association with cardiovascular risk factors in older adults in Primary Care. METHODS: this cross-sectional study involves 1,322 older adults assisted in Basic Health Units in the northernmost part of Brazil. Data were collected in 2020, covering information on myocardial infarction, hypertension, diabetes, hypercholesterolemia, obesity, chronic kidney disease, and smoking. RESULTS: myocardial infarction affected 10.5% of older adults, being more common in men (11.4% vs. 9.8%; p=0.327). Diabetes (OR=5.27; p<0.001), hypertension (OR=5.24; p<0.001), kidney disease (OR=5.20; p<0.001), and obesity (OR=2.87; p<0.001) significantly increased the odds of myocardial infarction. CONCLUSIONS: myocardial infarction affected 10% of older adults, and cardiovascular risk factors heightened this probability. Healthy lifestyle promotion and regular health monitoring are essential for its prevention.

Bertelli et al. (2025) conducted a cross-sectional in Myocardial infarction (n=1,322). Diabetes vs. Absence of diabetes was evaluated on Odds of myocardial infarction (OR 5.27, 95% CI 3.21-8.60, p=<0.001). Traditional cardiovascular risk factors, including diabetes (OR 5.27), hypertension (OR 5.24), kidney disease (OR 5.20), and obesity (OR 2.87), significantly increased the odds of myocardial infarction in older adults treated in primary care.
