Several non-invasive methods are currently used to assess vascular stiffness. Pulse wave velocity (PWV) and the augmentation index (AIx) are the two major non-invasive methods of assessing arterial stiffness. A large amount of evidence indicates that carotid-femoral PWV is an intermediate endpoint for cardiovascular (CV) events, either fatal or non-fatal. Central AIx and pulse pressure have shown an independent predictive value for CV events in hypertensives and patients with coronary disease. Studies of arterial stiffness in patients with cardiovascular emergencies and acute coronary syndromes, respectively, are missing.
We performed measurements of arterial stiffness parameters using the TensioMed Arteriograph in 34 patients admitted for acute coronary syndromes (ACS), 24 hours after admission. The study group included 28 males (82.4%) and mean age was 61.7 ± 14.07 years. Arterial stiffness parameters as aortic PWV, aortic AIx, central systolic blood pressure (aortic SBP), central pulse pressure (aortic PP) were analyzed in relation to clinical, historical and paraclinical parameters in order to describe particularities in this patient population. We compared the results with an age and sex adjusted population of 34 controls randomly selected from the most recent Romanian cross-populational statistical survey, SEPHAR II.
In our group, 45.7% of patients were hypertensive and 37.1% were diabetic. Most of the patients were on treatment with ACE inhibitors (91.4%) and beta-blockers (80%), while 71.1% were on intravenous or oral nitrates. Mean stiffness parameters in this group were: aortic AIx=28.51 + 10.81, with only 14.8% of patients showing normal values; aortic PWV = 9.71 ± 1.82 m/s; aortic SBP = 121.71 ± 21.07 mm Hg; aortic PP = 44.39 ± 13.74 mm Hg. No correlations were identified in this small group between arterial stiffness parameters and treatment, history of hypertension or diabetes, type of ACS and angiographic coronary anatomy. While aortic AIx was clearly abnormal, reflecting changes in endothelial function and waves’ reflection, the other parameters of arterial stiffness were not different from other patient populations.
Aortic AIx is abnormally increased in patients with acute coronary syndromes. Parameters of arterial stiffness in patients with ACS are not related to treatment, type of coronary disease or previous patient history.
