Correlation study of peripheral vascular atherosclerosis with cardiac diastolic function

Abstract

Objective To study the correlation of the peripheral vascular atherosclerosis with cardiac diastolic function. Methods A total of 252 elderly patients from May 2013 to March 2015 were selected, who was diagnosed with peripheral arterial plaque. According to the level of left ventricular diastolic dysfunction, these patients were divided into mild group (n=120) and moderate group (n=132). The baPWV, ankle arm index, the peak early diastolic mitral valve blood flow velocity (E), E/peak late diastolic mitral valve blood flow velocity (A) and E/early diastolic mitral valve ring motion velocity ratio (E') were compared. The relationship between baPWV, ankle arm index and E/A, E/E ' were analyzed. Results The age of mild group was significantly lower than that of the moderate group(P 0.05). Conclusions baPWV, ankle arm index are noninvasive methods to assess artery elasticity, to evaluate normal ejection fraction, no obvious clinical symptoms of left ventricular diastolic dysfunction, take preventive measures timely. This has a significant guiding significance to avoid of progression to reduce ejection fraction and decrease heart failure. Key words: Atherosclerosis; Cardiac diastolic function; Heart failure
