The standardized techniques of blood pressure (BP) measurement in the clinic are emphasized and it is recommended to replace mercury sphygmomanometer by a non-mercury sphygmomanometer. Out-of-office BP using home monitoring (HBPM) or ambulatory (ABPM) even automated office (AOBP) correctly measure patient’s genuine BP. Hypertension (HTN) treatment should be individualized based on cardiovascular (CV) risk level Based recent clinical study data proving benefits intensive lowering high...

BackgroundCoronary artery calcium (CAC) score is a clinically validated marker of cardiovascular disease risk. We developed and novel risk stratification system based on deep-learning-predicted CAC from retinal photographs.MethodsWe used 216 152 photographs five datasets South Korea, Singapore, the UK to train validate algorithms. First, using one dataset Korean health-screening centre, we trained deep-learning algorithm predict probability presence (ie, score, RetiCAC). stratified RetiCAC...
