Effectiveness of pulsatility index of carotid Doppler ultrasonography to predict cardiovascular events

Purpose The pulsatility index obtained from carotid ultrasonography is regarded as a marker of cerebrovascular resistance. The impact of PI on cardiovascular events has yet to be fully addressed, however. Method Fifty-four patients who underwent both carotid ultrasonography and coronary angiography were followed for 5. 9 3. 2 years. The relationship between cardiovascular events and PI was investigated. According to each threshold of PI for common carotid arteries, internal carotid arteries, and external carotid arteries, respectively, the patients were divided into two groups based on each threshold of PI value for common carotid arteries, internal carotid arteries, and external carotid arteries. The groups with CCA-PI 1. 71, ICA-PI 1. 20, and ECA-PI 2. 46 had a higher incidence of cardiovascular events, respectively. According to a multivariate Cox regression study adjusting for cardiovascular risk factors, high PI of CCA, ICA, or ECA was a risk factor for cardiovascular events.
