Abstract

The pathophysiology of myocardial infarction (MI) may differ depending on whether it occurs early or late in life. We tested the hypothesis that risk factor pattern differs according to the age at MI. We performed a matched case-control study in the population-based Malmö Preventive Project (n = 33 346), where 3687 individuals developed MI during 22 ± 7 years of follow-up (=cases). The cases were divided into quartiles (Q1-Q4) according to age at event and were assigned two matched controls free from MI during follow-up. We used conditional logistic regression to assess relationship between risk factors at baseline and case status within quartiles of age at incident MI. The median (range) age (years) at incident MI in Q1 was 52.9 (37.0-57.1), Q2 60.8 (57.1-63.6), Q3 66.6 (63.6-69.7), and Q4 73.5 (69.7-84.0). The odds ratio (95% CI) for incident MI associated with 1 SD increase of baseline cholesterol decreased with age of MI and was 1.68 (1.50-1.87) for Q1, 1.43 (1.28-1.61) for Q2, 1.27 (1.14-1.42) for Q3, and 1.08 (0.98-1.19) for Q4. Similarly, family history of MI had a stronger relationship with MI in Q1 than with MI in Q4 of MI age, whereas smoking displayed a U-shaped relationship. Exposure to the remaining risk factors di...Continue Reading

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.
