A drug-eluting stent (DES) is a peripheral or coronary stent (a scaffold) placed into narrowed, diseased peripheral or coronary arteries that slowly releases a drug to block cell proliferation.

What does DES mean in cardiology?

Drug-eluting stents (DES) are vascular prostheses used by interventional cardiologists to reopen and maintain patent coronary arteries narrowed by arteriosclerosis. The history of interventional cardiology began with balloon angioplasty in 1977. Sigwart et al. introduced the first bare metal stent (BMS) in 1986.

What drugs are used in DES?

DES consist of a standard metallic stent, a polymer coating, and an antirestenotic drug that is mixed within the polymer and released over time. First-generation DES include sirolimus-eluting stents (SES; 2003) and paclitaxel-eluting stents (PES; 2004) (TABLE 1).

What does DES mean medical terms?

What is DES? Diethylstilbestrol (DES) is a synthetic form of the female hormone estrogen. It was prescribed to pregnant women between 1940 and 1971 to prevent miscarriage, premature labor, and related complications of pregnancy (1).

What is the purpose of drug-eluting stent?

A stent is a small mesh tube inserted into an artery to keep it open. A drug-eluting stent is coated with a slow-release medication to help prevent blood clots from forming in a stent. Blood clotting in a stent can cause a future blockage (restenosis) and may lead to a heart attack.

What artery is nicknamed The Widowmaker?

A widowmaker is an informal term for a heart attack that involves 100 percent blockage in the left anterior descending (LAD) artery, says Stanley Chetcuti, M.D., an interventional cardiologist at the University of Michigan Frankel Cardiovascular Center.

How long do you have DAPT after stent?

The most recent American College of Cardiology/American Heart Association guidelines on duration of dual‐antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) with drug‐eluting stents (DESs) give a class I recommendation to continue DAPT for at least 12 months after an acute coronary syndrome (ACS) …

What's the meaning of DES?

Data encryption standard. … An encryption standard developed by IBM and adopted by the United States government in 1976 for non-classified applications. DES also was widely used by financial institutions for electronic financial transfers.

What is a DES doctor?

des. is, it’s a temporary title, like US presidents are “president elect”: Following a successful defence, the title of Doctor designatus (Dr. des.) may be used until the doctoral degree is gained.

Is DES still used?

Key Takeaways It reached a point where 56-bit was no longer good enough to handle the new challenges to encryption. … Triple DES is still used today, but it’s considered a legacy encryption algorithm. Note that NIST plans to disallow all forms of Triple-DES from 2024 onward.

Who created DES?

IBM developed DES in the 1970s based on Horst Feistel’s earlier design. It was submitted to the US Government’s precursor to the National Institute of Standards and Technology (NIST) in response to calls for a data-protection algorithm.

What is DES in security?

The Data Encryption Standard (DES) was a standard used by the United States government to encrypt and secure sensitive information. The DES was submitted by IBM to the United States government in the 1970s to secure unclassified, yet sensitive, government information.

When can I stop Plavix after a stent?

The data “suggest that all patients with drug-eluting stents should continue to take [Plavix] for at least 12 months after [stent implantation], and possibly indefinitely,” Eisenstein and colleagues conclude.

How many heart stents can a person have?

Patients Can’t Have More Than 5 To 6 Stents In Coronary Arteries: A Myth.

What percent of blockage requires a stent?

By clinical guidelines, an artery should be clogged at least 70 percent before a stent should be placed, Resar said. “A 50 percent blockage doesn’t need to be stented,” he said.

What are the disadvantages of stents?

• Re-narrowing of your artery. When angioplasty is combined with drug-eluting stent placement, there’s a small risk the treated artery will become clogged again. …
• Blood clots. Blood clots can form within stents even after the procedure. …
• Bleeding. You may have bleeding in your leg or arm where a catheter was inserted.

How long do you have to take blood thinners after a stent?

It has been common practice for patients who have had a stent placed to clear a blocked artery to take an anti-clotting drug (such as Plavix, Effient, or Brilinta) plus aspirin for 12 months after the procedure. Taking these two medications, called dual anti-platelet therapy, reduces the risk of forming blood clots.

What is the Dapt score?

The DAPT score is a clinical prediction score assessing ischemic and bleeding risks at 12 to 30 months following percutaneous coronary intervention (PCI) to inform the duration of dual antiplatelet therapy (DAPT).

Which artery is the most common to have blockage?

Although blockages can occur in other arteries leading to the heart, the LAD artery is where most blockages occur.

Can you Stent a 100 blocked artery?

“Patients typically develop symptoms when an artery becomes narrowed by a blockage of 70 percent or more,” says Menees. “Most times, these can be treated relatively easily with stents. However, with a CTO, the artery is 100 percent blocked and so placing a stent can be quite challenging.”

Does apple cider vinegar clean arteries?

Although we’re not sure where this claim originated from, we do know there is no scientific evidence proving apple cider vinegar clears clogged arteries. In fact, vinegar should not be substituted for standard treatment.

What does DES stand for encryption?

What is Data Encryption Standard (DES)? Data Encryption Standard (DES) is an outdated symmetric key method of data encryption. It was adopted in 1977 for government agencies to protect sensitive data and was officially retired in 2005.

What is the heart of Data Encryption Standard DES?

The heart of DES is the DES function. The DES function applies a 48-bit key to the rightmost 32 bits to produce a 32-bit output. to 48 bits. Although the relationship between the input and output can be defined mathematically, DES uses a Table to define this P-box.

What does Des stand for in government?

The Department of Economic Security (DES) is the safety net agency for the State of Arizona. As one of the largest agencies in state government, DES serves more than 2 million Arizonans annually through more than 40 programs that address the social and economic needs of those we serve.

How does DES work?

DES works by encrypting groups of 64 message bits, which is the same as 16 hexadecimal numbers. To do the encryption, DES uses “keys” where are also apparently 16 hexadecimal numbers long, or apparently 64 bits long. However, every 8th key bit is ignored in the DES algorithm, so that the effective key size is 56 bits.

Why is DES used?
