A new research shows that more people survive major heart attacks and have fewer problems if doctors use a mini-vacuum to clear out an artery blockage instead of pushing it aside to help blood flow. Suctioning out a clot before implanting a stent could lead to wider use in heart attack treatment.
Most heart attacks occur when a buildup of plaque in a coronary artery ruptures and a blood clot forms that blocks the flow of oxygen-rich blood to the heart. The most preferred treatment is an angioplasty to reopen the artery.
Doctors would use a procedure that would snake a tube through a blood vessel to the blocked artery and use a small balloon to compress the blockage and restore blood flow. A small metal-mesh stent is placed to keep the artery open. A bad thing about the procedure is that sometimes pieces of the clot or plaque breaks off and plugs the tinier vessels to restrict the blood flow to the heart.
