Heart attack therapy: new stent - a vascular support dissolves by itself
The cardiological university clinic of the St. Josef Hospital was the first in Bochum and the surrounding area to successfully use a 44-year-old heart attack patient with a novel, self-dissolving stent. This special vascular support enables clinical director Prof. Dr. Andreas Mügge and his team to treat risky constrictions in the coronary arteries much more gently.
The new stent was used quickly and without any problems in a short inpatient stay by catheter. The previous stents, which are used for infarctions and other diseases, are metal stents that remain in the body for a lifetime. Occasional side effects resulting from this are now prevented by the new method.
The first cardiologist trained and certified in Bochum for this is senior physician Dr. Kaffer Kara: “It is a newly developed stent that consists of lactic acid crystals that remain stable for three to six months. They are then gradually absorbed through the blood without the patient noticing it. During this time, a special coating prevents tissue proliferation and thus renewed vasoconstriction. These stents only stabilize the vessel wall until the injuries have healed again and the vessel performs its function again on its own. And because no foreign material remains in the coronary artery, the risk of thrombosis and thus possible re-narrowing decreases in the long term. ”
Clinic director Prof. Andreas Mügge sees decisive advantages in the new therapy procedure: “With this we are also increasing the quality of patient care. So far, diseased vessels have been repaired purely mechanically. The stents used so far help the patient well, but they also remain in the vessel for the rest of life. We are pleased to be able to treat narrowed vessels that are ill in the future without leaving long-term residues. We give the vessel the opportunity to regenerate. And even with this procedure, the patient is not burdened unnecessarily, anesthesia is not necessary. "
Heart disease is the leading cause of death worldwide. Coronary heart disease (CHD) is at the top. In CHD, the arteries that supply the heart with blood constrict or clog through the formation of plaque. Plaque consists of fat, cholesterol, lime and other deposits that accumulate on the inside of the vessel. Over time, this plaque hardens and constricts the arteries, restricting the supply of oxygen to the heart muscle. Plaque can also tear open and cause blood clots on the surface of the plaque. Decreased or blocked blood flow to the heart can lead to angina pectoris (chest pain) or heart attack. (pm)
