Abstract

Background: Limited data is available on the potential value of estimated cardiovascular event risk for prediction of left ventricular (LV) remodeling and size of infarcted tissue after ST-elevation myocardial infarction (STEMI).

Methods: Therefore, we assessed in a consecutive series of patients with first STEMI, successful primary percutaneous coronary intervention (PCI), and single-vessel disease the potential relationship between the Framingham Risk Score and parameters of both LV remodeling and infarct tissue characteristics, as determined with contrast-enhanced (CE) cardiovascular magnetic resonance (CMR) 6 months after the index event. Parameters of LV remodeling were end-diastolic and end-systolic volumes, ejection fraction, and wall motion score index; infarct tissue characteristics comprised core, peri, and total infarct size, and transmural extent.

Results: A total of 25 patients (21 men, 56 ± 10 years) were studied, and the mean Framingham Risk Score was 14.1 ± 5.8%. There was a significant relation between Framingham Risk Score and multiple parameters of LV remodeling: LV ejection fraction, end-diastolic volume, end-systolic volume, and wall motion score index after 6 months (r=-0.55-0.76; p=0.000 for all). Framingham Risk Score showed no relation with various infarct tissue characteristics (ns). Male gender was the only component of the Framingham Risk Score that correlated individually with a few parameters of LV remodeling: LV end-diastolic volume and end-systolic volume (p=0.000 for both).

Conclusion: In a series of consecutive patients with first STEMI, successful primary PCI, and single-vessel coronary artery disease, we observed a significant relation between the Framingham Risk Score and several CMRbased parameters of LV remodeling. The results of our small hypothesis-generating study underline the supremacy of multifactorial risk scores as tools for prediction of unfavorable cardiovascular outcome. Additionally, the data support the hypothesis that there might be a future role for a novel and specific multifactorial risk score in predicting unfavorable LV remodeling, which finally could trigger risk-adjusted preventive measures.
