INTRODUCTION: Since mortality and morbidity of coronary artery disease are high, there is a need for non-invasive diagnostic methods for early diagnosis and prediction of ischemic heart disease (IHD) outcome. This study aimed to assess the relationship between angiographic findings, the Presystolic wave (PSW) and some of the ischemic related parameters in echocardiography of the patients with chronic stable angina.
MATERIALS AND METHODS: This cross-sectional study was conducted on the patients with chronic angina pectoris who referred to a tertiary hospital for coronary angiography in Mashhad, Iran. Demographic and medical history of the patients, as well as echocardiography findings, including ejection fraction (EF), regional wall motion abnormalities (RWMA), PSW and diastolic function were recorded. Angiographic findings, including SYNTAX score were also assessed.
RESULTS: A total of 220 patients (132 males and 88 females) with the mean age of 62.43 ± 11.40 years old participated in this study. The prevalence of PSW was 49.1%. The absence of the PSW was related to more RWMA (P =.002), and higher stages of left ventricular diastolic dysfunction (LVDD) (P =.029) and higher SYNTAX score (P =.001). There was a significant association between the absence of the PSW and EF categories, especially in severe LV systolic dysfunction (LVEF < 30%) (P =.001).
CONCLUSIONS: The findings of this study revealed that PSW is strongly associated with the SYNTAX score. The absence of the PSW may indicate patients at high-risk clinical status (higher SYNTAX score, severe systolic dysfunction, more RWMA, and higher stages of LVDD).
