Each volunteer had his or her heart rate and blood pressure measured at rest, as well as coronary vascular conductance, a Doppler ultrasound measure of blood flow through the coronary blood vessels of the heart.
Transcatheter aortic heart valve surgery uses a small, collapsible heart valve, packaged within a balloon-expandable stent, similar to what is used routinely to open and reinforce coronary blood vessels.
Moreover, the medication Paclitaxel, which coats the stent, inhibits any negative effects on the coronary blood vessels that may result from the minimally-invasive procedure.
Trends were observed in data from tests of artery movement and function, demonstrating a potential restoration of unstented artery movement to coronary blood vessels after the stent was absorbed -- something that is not possible with permanent metal-based stent implants.
By carrying this gene vector into the coronary circulation, it should help the cells that form coronary blood vessels grow.
His team found that even in the presence of oxygen levels that would not normally trigger vessel dilation, drugs that lower intracellular ATP concentrations still open coronary blood vessels.
The development of coronary blood vessels during zebrafish heart regeneration has been postulated to occur in the same way as the heart and vessels were originally formed in the embryo.
It also improves the blood flow to the heart by improving the heart's ability to have its coronary blood vessels dilate.
Positive results from AtheroGenics' Phase II clinical trial, known as CART-1, suggested that AGI-1067 had a direct anti-atherosclerotic effect on the coronary blood vessels, which included improvements in lumen volume, plaque volume and total vessel volume.
The finding is "very important" and supports the view that smoking-related heart attacks result from more than a simple accumulation of fatty plaques inside coronary blood vessels, says Bernard Gersh, a cardiologist at the Mayo Clinic in Rochester, Minn.
However, the applications of drug-eluting stents are not confined to the coronary blood vessels.
Catheter based interventions in coronary blood vessels can be associated with a risk of a major adverse clinical event (MACE) (predominately myocardial infarction) or reduced blood flow to the vessels downstream of the treatment site.
