DALLAS – June 22, 2020 – For decades, high-density lipoprotein (HDL) cholesterol has been dubbed “good cholesterol” because of its role in moving fats and other cholesterol molecules out of artery walls. People with higher HDL cholesterol levels tend to have lower rates of cardiovascular disease, studies have shown.
A patient who met many of the published safety guidelines for chloroquine therapy against COVID-19 was observed to have a very abnormal ECG pattern after treatment began, leading to multiple episodes of torsade de pointes (TdP), a life-threatening arrhythmia in which the lower chambers of the heart beat out of sync with the upper chambers.

Higher spirituality among stroke survivors was strongly linked to better quality of life for them and their caregivers who may also feel depressed, according to new research published today in Circulation: Cardiovascular Quality and Outcomes, an American Heart Association journal. May is American Stroke Month.
An interdisciplinary research team establishes a new technological pipeline to build a 3D map of the neurons in the heart, revealing foundational insight into their role in heart function and cardiac disease
Atrial fibrillation ranks among the most common heart conditions, and episodes are difficult to predict. Researchers have proposed a way to define cardiac state and have studied the dynamics before the cardiac rhythm changes from normal sinus to AF rhythm and vice versa. The work, appearing in Chaos and based on critical transition theory, looks to provide an early warning for those with paroxysmal atrial fibrillation with potential implications for future wearable devices.
The Cardiovascular Research Foundation (CRF) has announced that TVT Connect, the Structural Heart Summit, will take place online June 18-28, 2020. TVT Connect features expertly developed series, late-breaking clinical science, challenging cases, industry-sponsored sessions, and connection to a community of thought leaders from across the globe.
Transforming how common health conditions are diagnosed using point-of-care and wearable bio diagnostic devices is the goal of a new $2.2 million University of South Australia project.
Strokes are the fifth most common cause of death in the United States and a leading cause of disability among survivors. Fortunately, most strokes — more than 80% — are preventable by managing risk factors.
The information came from the Prospective Urban Rural Epidemiological (PURE) study which followed the participants an average of 10 years.
Many patients with heart disease face limited treatment options. Fortunately, stem cell biology has enabled researchers to produce large numbers of cardiomyocytes, which may be used in advanced drug screens and cell-based therapies. However, current image analysis techniques don’t allow researchers to analyze heterogeneous, multidirectional, striated myofibrils typical of immature cells. In the Journal of Applied Physics, researchers showcase an algorithm that combines gradient methods with fast Fourier transforms to quantify myofibril structures in heart cells with considerable accuracy.
