Objectives: Assessing pulse wave velocity (PWV) represents the most simple and non-invasive method to determine arterial stiffness. Our goal is to analyze PWV after the exercise test in coronary revascularized patients and its implications in stratifying secondary cardiovascular disease prevention programs. Material and method: We analyzed 63 coronary patients that were interventionally revascularized. Patients were included in a cardiovascular rehabilitation program. We analyzed: age, fasting glycemia, effort systolic blood pressure, the lipid profile and the E/A report. Using the Complior device we determined PWV at maximum 15 minutes after the exercise test. We determined as risk factors: arterial hypertension, type 2 diabetes, CT>175 mg/dl, TG>150 mg/dl and LDL>100 mg/dl. Taking into account the presence of the risk factors we regrouped the initial group as it follows: group 1 - coronary patients with 1-2 risk factors and group 2 - coronary patients with more than 3 risk factors. Results: After the exercise test, PWV had an augmentated value for the whole group. Coronary patients who only had 1-2 risk factors and PWV after the exercise test of =10 m/s had a good lipid profile and diastolic function. Coronary patients with more than 3 risk factors and PWV of >10 m/s had a metabolic risk profile. Conclusions: Assessing PWV after the exercise test allows us to stratifiy the risk when starting the rehabilitation program (10 m/s=PWV>10 m/s) as well as modulate the secondary cardiovascular disease prevention measures.
