Background: The utility of screening for the degree of common carotid artery (CCA) stenosis as a predictor of cardiovascular disease (CVD) in a general population remains unclear.

Methods And Results: We studied 4775 Japanese men and women whose CCA was measured using bilateral carotid ultrasonography at baseline (April 1994-August 2001). We calculated the degree of stenosis as a percentage of the stenotic area of the lumen in the cross-section perpendicular to the long axis.

Background: We previously developed risk models predicting stroke, coronary heart disease (CHD), and cardiovascular disease (CVD) among Japanese people from the Suita Study. Yet, applying these models at the national level was challenging because some of the included risk factors differed from those collected in the Japanese governmental health check-ups, such as Tokutei-Kenshin. We, therefore, conducted this study to develop new risk models for stroke, CHD, and atherosclerotic CVD (ASCVD), based on data from the Suita Study.

Hypertension is a significant risk factor for heart failure (HF). Since hypertension definition varies across guidelines, identifying blood pressure (BP) categories that should be targeted to prevent HF is required. We, therefore, investigated the association between hypertension per the 2017 American College of Cardiology/American Heart Association (ACC/AHA) and 2018 European Society of Cardiology/European Society of Hypertension (ESC/ESH) guidelines and HF risk.
