Extracting Angina Symptoms from Clinical Notes Using Pre-Trained Transformer Architectures [PDF]
AMIA Annual Symposium 2020, 2020 Anginal symptoms can connote increased cardiac risk and a need for change in cardiovascular management. This study evaluated the potential to extract these symptoms from physician notes using the Bidirectional Encoder from Transformers language model fine-tuned on a domain-specific corpus.

Novel Classification of Ischemic Heart Disease Using Artificial Neural Network [PDF]
Computing in Cardiology 2020, 2020 Ischemic heart disease (IHD), particularly in its chronic stable form, is a subtle pathology due to its silent behavior before developing in unstable angina, myocardial infarction or sudden cardiac death. Machine learning techniques applied to parameters extracted form heart rate variability (HRV) signal seem to be a valuable support in the early ...

Рациональная фармакотерапия в кардиологии, 2020 Aim. To evaluate the practice of prescribing antianginal/antiischemic therapy in patients who, after acute myocardial infarction (AMI), retained typical clinical manifestations of stable angina.Material and methods. The registry includes 160 patients who

Non-Linear Dynamics In Patients With Stable Angina Pectoris [PDF]
arXiv, 2001 We investigate the clinical and prognostic significance of fractal dimension and detrended fluctuation analysis by comparing the group of patients with stable angina pectoris without previous myocardial infarction with the group of age-matched healthy controls.

ESC Heart Failure, EarlyView.Abstract Aims Wild‐type transthyretin cardiac amyloidosis (ATTRwt) is a cardiomyopathy causing myocardial hypoperfusion and impaired cardiac mitochondrial function. Trimetazidine is an antianginal agent used in patients with stable angina pectoris, which improves cardiac contractility and mitochondrial function.

Changes in the Hurst exponent of heartbeat intervals during physical activities [PDF]
arXiv, 2002 The fractal scaling properties of the heartbeat time series are studied in a controlled ergometric regime using the Hurst rescaled range R/S analysis. The long-time "memory effect" quantified by the value of the Hurst exponent $H>0.5$ is found to increase during progresive physical activity at healthy subjects in contrast to those having stable angina ...

European Journal of Heart Failure, EarlyView.Summary of the machine learning clustering methodology and results of the study. Clusters are identified using machine learning approach in the learning set population evaluating specific combinations of multiple characteristics. Then identified clusters are predicted and tested in the learning set to evaluate their association with outcomes.

Predicting physiological developments from human gait using smartphone sensor data [PDF]
arXiv, 2017 Coronary artery disease, heart failure, angina pectoris and diabetes are among the leading causes of morbidity and mortality over the globe. Susceptibility to such disorders is compounded by changing lifestyles, poor dietary routines, aging and obesity.
