Nsaids And Cardiovascular Disease: Minimizing The Risks

NSAIDS could increase heart attacks by 31% | quick tip 17

There are several factors to consider when evaluating the potential risk of NSAID therapy. The first is the duration of treatment. The risk of having a heart attack or stroke is extremely small over a short course of therapy , such as would be the case in treating acute pain from a musculoskeletal injury like tendonitis. Another important consideration is dose and frequency. The risk tends to increase with higher doses and increased frequency. The third factor is whether the person has existing cardiovascular disease. In people without known cardiovascular disease, the absolute increase in risk is incredibly small .

My general principles for NSAID use are:

  • In all patients, I recommend the lowest effective NSAID dose for the shortest duration of time to limit potential side effects.
  • In people without known cardiovascular disease, the increase in risk is so minimal that it rarely influences my decision about whether to use NSAIDs.
  • In patients with known cardiovascular disease, I might advise an alternative treatment. Many patients with pre-existing heart disease can be safely treated with short courses of NSAIDs. However, the choice of specific NSAID and dose is more important in these patients. I generally recommend the nonselective NSAID naproxen or the COX-2 selective NSAID celecoxib, as studies have demonstrated that these two drugs may have the best safety profile in higher-risk patients.

    How The Review Was Done

    This summary is based on a meta-analysis of 754 randomized controlled trials that included 353,809 people. 280 trials compared NSAIDs with placebo, and 474 trials compared 2 different NSAIDs. The publication period was 1990 to 2011.

    In studies providing individual participant data, the average age at start of treatment was 61 years.

    NSAIDs included were coxibs, diclofenac, ibuprofen, and naproxen.

    Outcomes included major vascular events major coronary events heart failure and gastrointestinal complications .

    Can I Use Nsaids If I Already Have Heart Disease

    If you have heart disease, talk to your healthcare provider about the best medication to use for treating aches, pains, or a fever. NSAIDs are not recommended if youve had a recent heart attack or heart surgery, for example.

    People with existing heart disease or those who have a high risk of developing heart disease have a higher risk of non-fatal heart attacks when taking high-dose diclofenac, high-dose ibuprofen, or celecoxib. It is likely your provider will avoid prescribing these medications if you have heart disease. The studies previously discussed suggest that short-term naproxen may be the safest option for people with heart problems if an NSAID is needed.

    Your provider may also suggest avoiding NSAIDs altogether and recommend a pain reliever like acetaminophen for occasional use. If your provider does tell you to take an NSAID, they will probably suggest you take it at the lowest dose and for the shortest period of time possible. If you are concerned about your heart risks, be sure to discuss this with your provider.

    Nsaids: Understanding The Fda’s Updated Warning

    NSAIDs Greatly Increase Risk After the First Heart Attack

    The U.S. Food and Drug Administration recently issued a consumer update announcing the agency is strengthening an existing warning in prescription drug labels and over-the-counter drug facts labels to indicate that nonsteroidal anti-inflammatory drugs can increase the chance of heart attack or stroke, possibly leading to death. The change was announced in July and publicized by the New York Times on July 9, 2015.

    What The Researchers Found

    As shown in the Table below, compared with placebo,

    • coxibs and diclofenac increased major vascular events, major coronary events, and vascular death. For 1,000 people prescribed a coxib or diclofenac for 1 year, 3 more had major vascular events, 1 of which was fatal.
    • ibuprofen increased coronary events.
    • all NSAIDS roughly doubled the risk of heart failure. For 1000 people taking coxibs for 1 year, 4 more had heart failure.
    • all NSAIDS increased GI complications. For 1000 people taking coxibs for 1 year, 3 more had GI complications.

    Confirmation Of Nsaid Risk

    All NSAIDs, including naproxen, were found to be associated with an increased risk of acute myocardial infarction. Risk of myocardial infarction with celecoxib was comparable to that of traditional NSAIDS and was lower than for rofecoxib. Risk was greatest during the first month of NSAID use and with higher doses.

    Does this mean that taking a single dose on an NSAID could cause a heart attack? If you were at high enough risk, yes, probably. If youre at low risk, even short-term use could increase risk, however.

    With use for one to seven days the probability of increased myocardial infarction risk was 92% for celecoxib, 97% for ibuprofen, and 99% for diclofenac, naproxen, and rofecoxib.

    So, be careful with NSAIDs.

    ABSTRACT: Nonsteroidal anti-inflammatory drugs are commonly used to treat pain associated with a variety of medical conditions. Nonselective NSAIDs reversibly inhibit the enzyme cyclooxygenase in both of its isoforms, COX-1 and COX-2. An increased risk of cardiovascular events has been associated with the use of NSAIDs, especially of COX-2 selective NSAIDs. Current evidence suggests that naproxen, a nonselective NSAID, is associated with the lowest risk of cardiovascular events. Therefore, naproxen is the NSAID of choice in patients with high cardiovascular risk.

    News: Can Ibuprofen Increase Risk Of Heart Attack

    Does taking pain medicine increase risk of heart attack or stroke?

    Non-steroidal anti-inflammatory drugs like ibuprofen are on just about every store shelf in America. Millions of people use them whenever they feel the slightest bit of discomfort. But even though these medications are seemingly everywhere, that doesnt mean they dont carry with them potentially major risks.

    What Should A Gp Do Instead

    What should a GP do for common musculoskeletal and osteoarthritis pains? The simplest and most effective way to reduce risk from NSAIDs is to avoid their use in older people and prescribe an alternative whenever possible. NICE recommends paracetamol or a topical NSAID as first line for pain relief in older patients or the use of opioid analgesics. Where an NSAID cannot be avoided, naproxen together with a proton pump inhibitor is the least worst option. However, even with a PPI, patients will remain at increased risk of cardiovascular and renal harm from NSAIDs including naproxen.

    Nsaids May Increase Heart Attack Risk

    Millions of people take over-the-counter NSAID pain medicines when they have a headache, fever, chills, joint pain or various other aches and pains. A new study shows that NSAIDs are associated with increased risk for heart attacks . The increased risk begins within the first week to month a person starts taking them. NSAIDs include ibuprofen , naproxen , diclofenac , celecoxib , etodolac , indomethacin , Rofecoxib, diflunisal , and a withdrawn prescription drug called Vioxx. Acetominophen is not an NSAID.

    The StudyThe researchers reviewed 82 studies covering 446,000 people and found that: People who used NSAIDs at any dose for one week to one month had a 20 to 50 percent increased risk of suffering a heart attack during the study period. Rofecoxib doubled the risk and ibuprofen and naproxen each increased the risk 75 percent. Higher doses increased heart attack risk. For example, heart attack risk increased more than 50 percent if the recommended dose of ibuprofen was doubled from 200 to 400 mg three-times-day, and 75 percent if the dose of naproxen was raised from 250 to 500 mg twice-a-day. The risk did not continue to increase when the NSAIDs were taken for more than for one month. The increased risk dropped to below 11 percent one month after people stopped taking the NSAID. People most likely to suffer a heart attack associated with taking NSAIDs were the ones with major risk factors such as high blood pressure. high cholesterol, high blood sugar or high insulin.

    Heart Attack Risk Highest In First Month Of Nsaid Use

    With the aim of closing this research gap, the team reviewed 82 studies that looked at the incidence of heart attack with NSAID use.

    After screening the studies for eligibility, the researchers were left with eight studies that included a total of 446,763 men and women from Canada, Finland, and the United Kingdom. Of these individuals, 61,460 had experienced a heart attack.

    The researchers looked at the NSAID use of each participant, focusing on specific types, including ibuprofen, diclofenac, celecoxib, rofecoxib, and naproxen.

    Overall, the team found that individuals who used any of these NSAIDs at any dose for at least 1 week had a 20 to 50 percent increased risk of heart attack , compared with individuals who did not use NSAIDs.

    Looking at heart attack risk by individual NSAID use, the researchers identified a possible 100 percent increased risk with rofecoxib, and a possible 75 percent increased risk for both ibuprofen and naproxen.

    The team uncovered evidence that suggests the first month of NSAID use poses the highest risk of heart attack, particularly if the drugs are taken at high doses.

    When Do Nsaids Become Dangerous

    Painkillers like ibuprofen can increase the risk of heart ...

    Just as with any medication, the use of NSAIDs comes with its benefits and risks. We will work with you to ensure that if NSAIDs are necessary, their benefits far outweigh the increased risk of heart attack or stroke. Generally speaking, however if we do have a different, safe, but similarly effective option, we will pursue it. Otherwise, the following are some ways to reduce your risk of heart attack or stroke when taking NSAIDs

    • Take the lowest possible dose to get relief
    • Take it for the shortest period of time to get relief
    • Do not drink while taking NSAIDs
    • Try other pain relievers such as acetaminophen/Tylenol instead
    • Take NSAIDs only on the orders of your cardiologist.

    Mechanism Of Cv Increased Risk Related To Nsaid Administration

    Based on previous assumptions, it seems that the higher the level of COX-2 inhibition and the lower the level of COX-1 inhibition, the greater the thrombotic risk related to NSAIDs. As suggested in previous literature, the extent of inhibition of COX-2-dependent prostacyclin may represent an independent key determinant of the increased risk of myocardial infarction among NSAIDs with nonfunctional suppression of platelet COX-1. Therefore, the assessment of whole blood COX-2 may represent a surrogate end point to predict the CV risk of these drugs. Nevertheless, the increased thrombotic risk related to NSAIDs is mainly but not only related to the COX-2 potency of each molecule and such results need to be confirmed in clinical settings, since questions still remain about the exact mechanisms underpinning NSAID-associated CV events.

    In fact, as shown by Warner and colleagues, nimesulide is a preferential COX-2 inhibitor but in contrast to coxibs, it seems to exhibit no significant CV toxicity. Moreover, Lapi and colleagues recently showed that nimesulide does not show a statistically significant increase in the number of cerebrovascular events.

    The necessity to use the lower effective dose for a shorter period of time was recently noted by the US Food and Drug Administration about the thrombotic risk related to NSAIDs .

    Even Short Term Nsaid Use Increase Risk After Heart Attack

    It is fairly known that pain killers in the group of non steroidal anti inflammatory drugs increase the cardiovascular risk in healthy individuals as well as those with a prior heart attack. Olsen and associates checked whether there is a relationship between the duration of use of NSAIDs and cardiovascular risk. The study evaluated over eighty three thousand patients thirty years or more in age admitted with first myocardial infarction between 1997 and 2006. There were over thirty five thousand reinfarction or death during the period of evaluation. About forty two percent of the subjects had received NSAIDs. They noted a hazard ratio of 1.45 with the use of NSAIDs for increased risk of death or myocardial infarction with the use of NSAIDs. While the increased risk started immediately on initiating certain NSAIDs, it occurred within one week with others. Authors suggested the limiting of NSAID use in those with prior myocardial infarction even though we need a good randomized controlled trial to clarify this issue further.

    Nsaids And Your Heart Do They Increase The Risk Of Heart Attack And Stroke

    NSAIDs or nonsteroidal anti-inflammatory drugs such as ibuprofen, marketed as Motrin and Advil and naproxen, often purchased as brand-name Aleve are front and center of pain aisles in just about every pharmacy or grocery store. These medications are available over the counter and used widely because of their exceptional effectiveness in relieving mild to moderate pain. Unlike acetaminophen or Tylenol, they also bring an anti-inflammatory component to the equation, meaning they are very useful for injuries and other inflammatory conditions.

    However, we have known since an FDA warning in 2005, that NSAIDs do, in fact, increase the risk of a heart attack and stroke. 10 years later, the FDA strengthen their warning to help ensure consumers were well educated about the risks. We have always known that some NSAIDs increased the risk of gastrointestinal bleeding, but heart attack and stroke risk is a relatively newer finding prompted by the recall of Vioxx in 2004 which may have caused over 100,000 heart attacks during the few years that it was sold.

    The current generation of NSAIDs:

    • Pose a higher risk of heart attack and stroke even with short term use a few to several weeks of use
    • This risk is increased the longer the NSAID is taken
    • The risk is also increased when higher doses are taken
    • Risks are highest for those with existing cardiovascular disease, but even those without heart disease are at elevated risk

    The Cyclooxygenase Enzyme And Its Physiologic Roles

    Study: Some heartburn drugs increase risk of heart attack

    NSAIDs are cyclooxygenase inhibitors. COX is an enzyme, which produces prostaglandin H2 from arachidonic acid. PGH-2 is a metabolite converted into prostanoids by tissue specific enzymes.

    Two basic isoforms of cyclooxygenase are known to date: COX-1 and COX-2. Initially, COX-1 was thought to be the constitutive form of the enzyme playing an important role in physiologic functions of the human body. At the same time, COX-2 was considered strictly inducible and thought to be responsible for inflammation and pain under pathologic circumstances. Recently, this theory was proven to be too simplistic. It is now known that COX-2 is permanently present in several tissues of the human body and plays an important role in multiple physiologic processes.

    With regards to the most common serious ADRs of NSAIDs, it is important to understand the role of COX-1 in the formation of protective prostaglandin E2 and prostacyclin . Both of these play a protective role in the gastric mucosa. In thrombocytes, COX-1 forms thromboxane A2 , which is a prostanoid antagonizing the anti-thrombotic and vasodilating effect of PGI-2 formed in the arteries by both COX isoforms. Within the kidney, PGE-2 formed by COX-1 plays a decisive role in the regulation of glomerular filtration, while PGI-2 produced by COX-2 affects renin secretion. Finally, products of both COX isoforms play a role in the kidney regulating excretion of sodium and water.

    Fda Strengthens Warning That Nsaids Increase Heart Attack And Stroke Risk

    • By Gregory Curfman, MD, Assistant Professor of Medicine, Former Editor-in-Chief, Harvard Health Publishing

    Back in 2005, the FDA warned that taking nonsteroidal anti-inflammatory drugs like ibuprofen and naproxen increased the risk of having a heart attack or stroke. In July 2015the FDA took the unusual step of further strengthening this warning. This was done on the advice of an expert panel that reviewed additional information about NSAIDs and their risks. Because ibuprofen and naproxen are available over-the-counter and so widely used, its important to be aware of the ibuprofen warnings and naproxen warnings and to take steps to limit the risk.

    Many people take NSAIDs to relieve mild to moderate pain. These medications may be particularly effective in conditions in which pain results primarily from inflammation, such as arthritis or athletic injury. While you can buy ibuprofen and naproxen on your own, doctors commonly write prescriptions for celecoxib , diclofenac and other NSAIDs. Aspirin is also an NSAID, but it does not pose a risk of heart attack or stroke. In fact, aspirin is commonly used to prevent heart attacks and strokes. So, it is not covered by this warning.

    The FDA has noted the following ibuprofen warnings and naproxen warnings along with similar risks of other NSAIDs:
