ABSTRACT

BACKGROUND: The association between arterial stiffness (AS) and stable coronary artery disease (CAD) has been previously demonstrated. Whether increased arterial stiffness is associated with severe CAD in patients with acute coronary syndrome (ACS) is less explored.

AIM: We aim to investigate the relationship between AS parameters and the extent and severity of CAD in patients with ACS.

METHODS: The study population consisted of 275 patients with ACS. We measured various AS parameters including pulse wave velocity (PWV), augmentation index (AIx), and central pulse pressure (cPP). CAD extent and severity was evaluated by the number of vessels with greater than 70% stenosis.

RESULTS: The study population was predominantly men (77, 5%) with an average age of 56, 410, 6 years. One hundred and fifteen patients were diabetic and 97 were hypertensive. One hundred fifty patients were admitted for ST elevation myocardial infarction (54, 5%) and 37, 5% for non ST elevation myocardial infarction. Thirty six percent of patients had single vessel disease and 47, 6% of the study population had multivessel disease. At the multivariate analysis, a positive correlation was observed between the number of coronary vessels disease and PWV. PWV (OR=1,272; IC95% [1,090; 1,483]; p=0,002) and cPP (OR=1,071; IC95% [1,024; 1,121]; p=0,003) were also independent predictors of multivessel disease.

CONCLUSION: In patient with ACS, PWV is correlated with the extent of coronary artery disease, as measured by the number of vessels disease. PWV and cPP were also independent predictors of multivessel disease.
