What is a cardiac stent and when do you need one?



Every year, nearly one million Americans are implanted with cardiac stents. These tiny, wiry tubes of woven metal help open the coronary arteries that supply the heart muscle with blood. Although it seems that more blood flow to the heart is always better, the final verdict on stents is more complicated. In some cases, it's better to simply say no.

Stents have become commonplace because in some cases they are really lifesaving. In most heart attacks, one of the coronary arteries completely clogs and can not deliver oxygenated blood to the heart. If the artery is not reopened immediately, the affected part of the heart degenerates into useless porridge. Because stents are the most efficient and durable arterial reopening tools, they are almost always the best treatment for heart attacks. The sooner a stent can be used, the more likely the result is likely to be. So the next time you develop pancreatic pains, do not waste time and call for an ambulance.

Unfortunately, stents can also be To prevent blood sticking to a stent, you need to take aspirin daily for the rest of your life, and you must also take a second blood-thinning medicine for at least a few months, which makes you more susceptible to bleeding If you give up the medication too soon, the stent can quickly clot and recapture the entire artery and even if you are perfect with your pills, your body can slowly sabotage the stent by depositing several cell layers on its inner surface – which the s has an effect of more as a hundred layers of paint on the walls of your bedroom. Over time, you may need a second stent to open the first one.

Given the risks associated with stents, there are two common scenarios in which you should think twice before having a cardiologist permanently installed in your heart:

Proverb # 1: Your heart attack was present some time [19659009EinStentistnichthilfreichwennSiebereitseinenHerzinfarkthattenundnichtsofortbehandeltwurdenDieKoronararterieistzwarimmernochverstopftdervonihrversorgteHerzmuskelkannjedochbereitstotseinUndesmachtkeinenSinndentotenMuskelwiedermitBlutzuversorgenLeiderkönnenSiediesenTeildesHerzensnichteinfachsteckenumzusehenoberwirklichtotistDeshalbführenÄrzteeinenspeziellenTestdurchderals"viabilityscan"bezeichnetwirdDieserScanunterscheidettoteBereicheindenHerzzellenvonsolchendieeinfachindenWinterschlafgehenundmöglicherweisemitmehrBlutflusswiederzumLebenerwachenWennderScanpositivistkanneinStenthilfreichseinWennnichtkümmernSiesichnicht

Say-No-scenario no. 2: Chronic chest pain [19659010] If your chest often hurts during exercise, it may be because one of your coronary arteries is constricted. Therefore, part of the heart muscle does not get enough blood when it works hard, and it causes pain, forcing you to sit down and get the pulse back to normal. A stress test usually confirms the diagnosis.

Although it seems intuitive that opening the artery would relieve pain, recent studies suggest that medications can provide equivalent relief and overall results. The most effective are beta-blockers, nitrates and ranolazine. (Of course you should also take measures to lower your blood pressure and your cholesterol.) If you smoke cigarettes, of course you should stop.)

The exceptions

There are two exceptions when a stent can be a better choice for chronic pain In the chest: First, if your pain is not controlled by pills or you do not like the side effects of pills, a stent is a good option Secondly, if your pain is caused by severe blockages – dangerous locations – such as the left aorta, the Nurturing more than half of your heart or all three coronary arteries – you may need stents or even a bypass surgery to lower your long-term risk of bad events such as heart attacks or death.

Like all medical treatments, stents have pros and cons They have been celebrated as miracle treatments – and sometimes really – but they are not the solution to every problem and it is you yourself (and your heart) guilty that you have no better alternative.
