Association between Arterial Stiffness and Left Ventricular Diastolic Dysfunction in Stable Coronary Heart Disease

Background Arterial stiffness is one of coronary heart disease risks that exacerbates vascular and myocardial function. Arterial stiffness causes an increase in systolic pressure and decreases diastolic in the left ventricle. Cardio-ankle vascular index (CAVI) is a new tool used to detect arterial stiffness. Objectives Analyzing the correlation between arterial stiffness using cardio-ankle vascular index with left ventricular diastolic dysfunction in patients with stable coronary heart disease Method The study was conducted from March to May 2015. Data collected were age, gender, laboratory examination, echocardiography for diastolic function, ejection fraction, and CAVI. The data then were analyzed using SPSS (SPSS, Inc., Chicago, IL). Result The samples were 32 respondents (78.1% of males, average age of 58.22±7.6 years). The result of CAVI statistic test with diastolic dysfunction was r =0.394 and p value =0.026 (α =0.05). Conclusion There was a significant positive correlation between Arterial stiffness using CAVI with left ventricular diastolic dysfunction.
