Tsimane indigenous South Americans have lowest prevalence of coronary atherosclerosis of any population yet studied

The Tsimane people – a forager-horticulturalist population of the Bolivian Amazon – have the lowest reported levels of vascular ageing for any population, with coronary atherosclerosis (hardening of the arteries) being five times less common than in the US, according to a study published in The Lancet and being presented at the American College of Cardiology conference.

New stenting tool found to be less painful and cheaper than current methods

A new tool for assessing the narrowing of the heart's arteries was found to be as effective as current methods and less painful for patients.

New gene-silencing drugs cut cholesterol levels by half in early research

The first in a new class of gene-silencing drugs, known as inclisiran, has been shown to halve cholesterol levels in patients at risk of cardiovascular disease.

New portable camera can photograph the retina without need for pupil-dilating eye drops

It's the part of the eye exam everyone hates: the pupil-dilating eye drops. The drops work by opening the pupil and preventing the iris from constricting in response to light and are often used for routine examination and photography of the back of the eye.

Salk scientists develop new way to find responders to lithium therapy

For roughly one-third of people diagnosed with bipolar disorder, lithium is a miracle drug, effectively treating both their mania and depression. But once someone is diagnosed, it can take up to a year to learn whether that person will be among the 30 percent who respond to lithium or the 70 percent who do not.

Simple fix could eliminate unnecessary coronary stenting procedures

Physician researchers at Thomas Jefferson University suspect that some cases of coronary artery spasm go unrecognized and are incorrectly treated with stents.

Modern guidelines may miss some African-Americans eligible for statin therapy

African Americans experience a disproportionately high risk of cardiovascular disease, and statin treatment can be an important tool to lower the risk of plaque building up in the arteries.

Study sheds light on cellular mechanisms that enable prostate cancer cells to form secondary tumours

New King's College London research sheds light on the cellular mechanisms which enable cancer cells to escape the prostate and spread to other parts of the body.

MIT researchers devise new strategy to make tumor cells more susceptible to cancer treatment

MIT researchers have devised a way to make tumor cells more susceptible to certain types of cancer treatment by coating the cells with nanoparticles before delivering drugs.

Early treatment with stem cells can safely help recovery in stroke patients, study shows

A multicenter trial looking at whether a single dose of millions of adult, bone-marrow-derived stem cells can aid stroke recovery indicates it's safe and well-tolerated by patients but may not significantly improve their recovery within the first three months, researchers report.

Methylation status of ten positions in genome correlates with all-cause mortality

Various chemical modifications in the genome determine whether genes are read or deactivated. Methyl labels in the DNA play a key role in this "epigenetic" regulation of gene activity.

Medications, PCI equally beneficial for treating complete blockage in heart's arteries

In patients with a complete blockage in the heart's arteries that persists over time, treatment with medications alone was found to be equal to percutaneous coronary intervention (PCI), a procedure to open blocked arteries, in terms of major adverse events over three years, according to a study presented at the American College of Cardiology's 66th Annual Scientific Session.

Circadian misalignments may favor diabetes development

Like almost all light-sensitive living beings, human beings follow biological rhythms set on a period of about 24 hours.

New markers linked to recurrence of erratic heartbeats in some patients after ablation therapy

Ablation procedures restore a regular heartbeat in patients who have a dangerous, abnormal heart rhythm called atrial fibrillation. But it doesn't always work. Now, a new study suggests that certain molecules are associated with the recurrence of erratic heartbeats in some patients after ablation therapy.

Study finds low utilization rates of life-saving medications for high-risk PE patients

Pulmonary embolism (PE), a blood clot in the lungs which causes shortness of breath and chest pain, is the third leading cardiovascular cause of death in the United States with more than 100, 000 lives taken each year.

Many Canadian family doctors still use manual devices to measure blood pressure, study shows

A study by researchers at the University of Montreal Hospital Research Centre (CRCHUM) shows that more than half of family doctors in Canada are still using manual devices to measure blood pressure, a dated technology that often leads to misdiagnosis.

Pacing program can lead to seven-fold reduction in fainting episodes

Patients with recurrent fainting episodes (syncope) who received a pacemaker delivering a pacing program designed to detect and stop the abnormal heart rhythms that precede syncope had a seven-fold reduction in fainting compared with patients in a placebo pacing group, according to research presented at the American College of Cardiology's 66th Annual Scientific Session.

Uninterrupted use of new anticoagulant reduces major bleeding events during atrial fibrillation ablation

Uninterrupted treatment with dabigatran, a non-vitamin K antagonist oral anticoagulant (NOACs), before, during and after ablation to treat atrial fibrillation significantly reduced the incidence of major bleeding events compared with uninterrupted use of the more established anticoagulant warfarin, according to research presented at the American College of Cardiology's 66th Annual Scientific Session.
