Scientists at Harvard University have broken new ground in applying 3D printing technology to the problem of damaged hearts, providing a potential new tool to keep blocked arteries open and the blood pumping freely.

One of the key symptoms of congestive heart failure is fluid accumulation in the lungs. Currently, people need to visit a clinic in order to check for such accumulation. Thanks to a new device, however, they may soon be able to perform checks whenever they want, in their own home.

If you have high blood pressure, then you likely already know that it's the leading cause of stroke, and a major risk factor for cardiovascular disease. So, besides things like medication, diet changes and exercise, what can be done to reduce it? Well, exposure to blue light may help.

Using data from nearly half a million people, researchers have developed a DNA test called a Genomic Risk Score (GRS), which can assess a person's genetic risk factor for developing heart disease. The test will allow doctors to combine a GRS with other factors to better target at risk individuals.

If doctors want to check someone's heart rhythm while that person is out and about, the patient is required to wear a Holter monitor. Now, however, UK scientists have developed what they claim is a cheaper, more comfortable and faster-performing alternative, in the form of the Heartsense monitor.

A large-scale meta-analysis collecting data from 79 trials has concluded that omega-3 supplements have little to no effect in preventing heart disease, stroke or death. The results contrast the common belief that omega-3 supplements confer a variety of beneficial cardiovascular protections.

A new meta-study has concluded that multivitamins and mineral supplements do not improve cardiovascular health or protect against heart attack and stroke. The systematic review suggests if a person is generally healthy then multivitamin/mineral dietary supplements confer no cardiovascular benefits.

In one of the first examples of gene-editing technology being effectively used to knock out the expression of a gene in non-human primates, researchers have lowered the blood cholesterol in monkeys by disabling a single gene in the liver.

Researchers at the University of British Columbia (UBC) have developed a surgery-ready smart stent that keeps watch for the early warning signs of narrowing arteries, and sends out a wireless signal to alert the patient and doctors.
