Inflammation in heart disease: do researchers know enough?

Anti-inflammatory therapies for cardiovascular disease are nearing the clinic. But whether scientists understand how inflammation contributes to fatty-deposit build-up well enough to target it effectively is open to debate.

Is there more to a healthy-heart diet than cholesterol?

A high-fat diet is thought to increase the risk of a heart attack. But some say that the long-held dogma of ‘bad’ cholesterol might be flawed.

Developing a vaccine against atherosclerosis

The notion that atherosclerosis can be prevented or mitigated by vaccination is now moving towards clinical trials. This strategy is based on the existence of autoimmunity to LDL, the cholesterol-carrying particles that accumulate in arteries. In this Comment, we…

Cardiovascular risks of climate change

Extreme heat events are now more frequent in many parts of the world as a result of climate change. The combined effects of heat, air pollution, individual age, and socioeconomic and health status are responsible for avoidable acute events of cardiovascular disease…

Pulling at the heart: COVID-19, race/ethnicity and ongoing disparities

Social determinants of health in the African diaspora drive the lack of disease testing, increased prevalence of comorbid disease and reduced access to drugs, resulting in disproportionately higher COVID-19-related mortality among Black individuals than the rest of…

Genetic and functional insights into the fractal structure of the heart

A genome-wide association study shows that myocardial trabeculae are an important determinant of cardiac performance in the adult heart, identifies conserved pathways that regulate structural complexity and reveals the influence of trabeculae on the susceptibility to cardiovascular disease.

The effects of endurance exercise on the heart: panacea or poison?

Moderate exercise improves cardiovascular health and is associated with physiological cardiac adaptations; by contrast, the hearts of endurance athletes can undergo maladaptations, including myocardial fibrosis and arrhythmias. In this Review, Parry-Williams and…
