Objectives
• Understand the risks associated with NSAID use in patients
with and without history of cardiovascular disease
• Identify what patients are at highest risk for cardiovascular
complications with NSAID use and when alternate therapies
should be considered
• Understand factors that limit risk of cardiovascular events
associated with NSAIDs
3
Questions
1. Do NSAIDs increase cardiovascular risk in those with and without a
history of known cardiovascular disease?
2. Are there any NSAIDs that confer less risk of cardiovascular events?
3. What settings should NSAID use be considered contra-indicated from a
primarily cardiovascular standpoint?
4. Are there any other settings where NSAID use should be avoided from a
cardioprotective standpoint?
4
History of NSAIDs
• Aspirin has been on the market for greater than 115 years
• The NSAIDs “class” constitute a chemically heterogenous group of compounds with drug specific
selectivity that provide shared therapeutic effects
•
Analgesic
•
Anti-inflammatory
•
Antipyretic
• Marketing of NSAIDs began ~1963 with indomethacin
• Since then over 20 additional NSAIDs have been developed
• Estimated 70 million prescription NSAIDs written each year in the United States
• Combining over the counter use of NSAIDs 30 billion doses are consumed annually
5
History of NSAIDs
• Approximately 15 years ago selective inhibitors of cyclooxygenase-2 developed
• Showed promise based on anti-pyretic, anti-inflammatory and analgesics effects as a class
• Variability of effects noted based on pharmacokinetics and pharmacodynamics
• Development continued with unique targets elucidated
• i.e. chemoprevention of colorectal carcinoma
• As dosage limits pushed with newer drugs toxicity profiles became increasingly apparent
•
Multiple NSAIDs demonstrated vascular toxicity represented by heart failure and new onset or worsening of hypertension*
• This culminated in newer agents suggesting increased risk of cardiovascular thrombotic effects
• This was a surprise as aspirin had been shown to be cardioprotective to events in doses up to 1500mg a day**

US Food and Drug Administration Public
Health Advisory
• December 2004 Health Advisory
•
“Physicians prescribing celecoxib or valdecoxib should consider the emerging information when weighing the benefits against risks for individual
patients. Patients who are at a high risk of gastrointestinal (GI) bleeding, have a history of intolerance to nonselective NSAIDs, or are not doing
well on nonselective NSAIDs may be appropriate candidates for COX-2 selective agents.”
•
“Individual patient risk for cardiovascular events and other risks commonly associated with NSAIDs should be taken into account for each
prescribing situation.”
•
“Consumers are advised that all over-the-counter (OTC) pain medicines, including NSAIDs, should be used in strict accordance with the label
directions. If use of an (OTC) NSAID is needed for longer than ten days, a physician should be consulted.”
• April 2005 News Release
•
FDA asks valdecoxib sales and marketing to be suspended in the US
•
FDA requires celecoxib and all other prescription NSAIDs to have black box warning including CV eveents
•
FDA urges OTC NSAIDs to have more specific warnings of CV and GI events

NSAID Cardiovascular Controversy Begins…
9
Why are we here today???
•
FDA announcement July 2015 strengthens warnings for cardiovascular or cerebrovascular events
•
Based on the advisory committees’ recommendations, the prescription NSAID labels were revised to reflect the following information:
•
The risk of heart attack or stroke can occur as early as the first weeks of using an NSAID. The risk may increase with longer use of the NSAID.
•
The risk appears greater at higher doses.
•
It was previously thought that all NSAIDs may have a similar risk. Newer information makes it less clear that the risk for heart attack or stroke is similar for all
NSAIDs; however, this newer information is not sufficient to determine that the risk of any particular NSAID is definitely higher or lower than that of any
other particular NSAID.
•
NSAIDs can increase the risk of heart attack or stroke in patients with or without heart disease or risk factors for heart disease. A large number of studies
support this finding, with varying estimates of how much the risk is increased, depending on the drugs and the doses studied.
•
In general, patients with heart disease or risk factors for it have a greater likelihood of heart attack or stroke following NSAID use than patients without these
risk factors because they have a higher risk at baseline.
•
Patients treated with NSAIDs following a first heart attack were more likely to die in the first year after the heart attack compared to patients who were not
treated with NSAIDs after their first heart attack.
•
There is an increased risk of heart failure with NSAID use.

NSAIDs and Cardiovascular Risk
• NSAIDs differ many ways
•
•
•
•
Chemical class
Chemical structures
Variability in the manner in which they inhibit COX-1 and COX-2 isoenzymes
Causes varying effect on:
• Antipyretic effects
• Analgesic effects
• Anti-inflammatory effects

NSAIDs and Cardiovascular Risk
• How do aspirin derivatives increase risk of atherothrombosis???
• NSAIDs – selective and/or non-selective in inhibiting cyclooxygenase
• COX-1: produces prostaglandins used for stimulation of typical body functions
• i.e. stomach mucous production, regulation of gastric acid and kidney water excretion
• COX-2: produces prostaglandins used for signaling pain and inflammation

NSAIDs and Cardiovascular Risk
• Has been proposed that the major cardiovascular complications are COX-2 inhibition
mediated as blocking COX-2 shifts prothrombotic or antithrombotic balance on endothelial
surfaces
• Increases in sodium and water retention  edema  hypertension  HF
• Loss of protective effects of COX-2 upregulation
• May lead to myocardial ischemia and infarction
• Can lead to larger infarct size, greater thinning ventricular wall in infarct zone and increased tendency for myocardial
rupture*
• Imbalance of production of “prostanoids”, a subclass of eicosanoids containing:
• Prostaglandins – mediate inflammatory and anaphylactic reactions
• Thromboxanes – mediate vasoconstriction
• Prostacyclins – an active part of the resolution phase of inflammation

Considerations
• What factors play a role in NSAIDs and potential adverse cardiovascular effects?
• Does dose of NSAID matter?
• How long can NSAIDs be used before risk unacceptable?
• Are there any patient types more at risk?
• Is risk the same for those for primary and secondary events?
• Which agents, if any, confer the most risk?
• Is there additive therapy that can diminish this risk?
• What evidence is out there to answer any of these questions?
• Most current knowledge from collections of post hoc analyses of subgroups of patients from studies designed to
look at non-cardiovascular diseases
• Focus has primarily been on COX-2 inhibitors with nonselective NSAID risk estimated primarily from metaanalyses and observational studies
18

• To date there are a number of large systematic reviews published covering randomized trials and non-randomized
pharmaco-epidemiological studies

• Many of these studies use the same data looking for different endpoints and to this point it is all that is available
•
PRECISION is coming…..
19
Does Dose Matter???
• From a heart failure and ischemic cardiovascular event standpoint there is little data
available to estimate risk but in the studies available there seems to be consensus
that “low dose” NSAIDs (especially short term) do not confer as significant a risk
• What is considered “high dose” of commonly used NSAIDs
• Ibuprofen > 1200mg daily
• Diclofenac > 100mg daily
• Naproxen >500mg daily
• Celecoxib > 200 mg daily
• Rofecoxib > 25g daily (no longer on the market)
20
What Duration of Treatment Matters??
• Very few time to event analyses are available to answer this
• Only a couple studies were randomized and designed specifically to look at this question but these were in
the setting of the immediate post operative period with coronary artery bypass grafting (CABG)
•
Findings here have been very consistent with COX-2 inhibitors leading to an absolute contra-indication in the immediate
weeks post CABG
• These studies prompted some analyses of duration to treatment risk in patients with history of myocardial
infarction

Hypertension Risks
• Generally well accepted that most NSAIDs carry risk of elevating blood pressure
• Effects seem dose-dependent and probably involves inhibition of cyclooxygenase-2 (COX-2) in the
kidneys
• Presumably reducing sodium excretion and increasing intravascular volume
• Hard to generalize severity of effects on blood pressure as specific agents vary greatly on their effects
• Indomethacin and Naproxen most consistently seem to cause greatest increases in mean arterial pressure (~34 mmHg)
•
Arch Intern Med. 1993;153(4):477.
• Some studies have shown potential of NSAIDs to antagonize most anti-hypertensive treatments with
the exception of calcium channel blockers
•
Hypertension. 2007;49(3):408
24
Heart Failure Risks
• Also generally well accepted as a potential risk for developing heart failure and significant risk noted in
NSAID users with history of heart failure
• ACC guidelines discourage use of all NSAIDs in patients with chronic heart failure for some years now
• AHA has published prior scientific statements recommending against use of NSAIDs, particularly COX-2
inhibitors, in patients with established heart failure independent of severity of disease

Cardiovascular Events: Myocardial Infarctions
• As the rofecoxib studies for alternative indications and doses found increasing incidence of increased
ischemic CV events….
•
•
Concern about celecoxib safety as only valdecoxib and rofecoxib left market
Need for cardiovascular data on nonselective NSAIDs arose
•
Concern as most countries allow non-prescription use
• JAMA. 2006: 296: 1633-1644
•
•
•
•
Looked at eligible studies of case-control or cohort design on CV events
Eligible studies had to report on cardiovascular risks associated with NSAID use
Used nonuse/remote exposure as the reference point for risk calculation
7086 titles evaluated (from 1985-2006)  only 23 titles included in analysis
•
Totaled > 86,000 events and had > 1,000,000 controls

NSAIDs and Cardiovascular Risk
• Through most studies average relative risks with gastrointestinal complications are estimated
around 4 but cardiovascular complications seem to center in the range of 1 to 2
• Limits power of data statistically
• Raises importance of risk variability estimates within study participants
• Low vs High risk
• Low vs High dose
• Risk between similar drugs
• Data seem to suggest some traditional NSAIDs at higher doses seem to confer similar
elevated risks to what was demonstrated with prior available COX-2 inhibitors
• But what about low dosing more consistently as with non-prescription use???

Cardiovascular Risk with Non-steroidal AntiInflammatory Drugs: Systematic Review
• Based on same protocol as earlier discussed JAMA article (same authors)
• Confined analysis to non-randomised controlled observational designs
• Prior placebo controlled trial had captured insignificant events but ongoing meta-analyses
and additional randomised data published now allowed for it
• Period reviewed this time was January 1985 to November 2010
• Pair wise data was plentiful enough to be powered appropriately
• As many of the values of pooled relative risk found to be close to 1 a sensitivity analysis was
conducted to strength of association with cardiovascular events
• Due to volume of analyses the sensitivity analysis was limited to pair-wise comparisons of
drugs as this was most important measure of relative harm

Cardio-protection with aspirin & NSAIDs
• Does NSAID induced COX inhibition affect the cardio-protective effects of aspirin therapy?
•
Quick Answer: we don’t know definitively at this point (likely ibuprofen)
• Cardio-protective effect diminished
•

•
•
Ibuprofen shown to inhibit irreversible platelet inhibition of aspirin
NEJM. 2001;345: 1809-1817
•

• Cardio-protective effect unaffected
•
J Clinical Pharmacology. 2002;42: 1027-1030
•
•
Celecoxib showed no effect on the pharmacodynamics of aspirin
Circulation. 2003;108: 1191-1195
•
Suggested that short term use of NSAIDs did not effect aspirin

Summary – ACC, AHA, and ACR
• All discourage use of all NSAIDs in patients with chronic heart failure
• All recommend against use of NSAIDs, particularly COX-2 inhibitors, in patients
with established cardiovascular disease
• All recommend NSAIDs be avoided in patients taking aspirin for cardioprotective
benefit
• If treatment becomes necessary in this patient population ibuprofen should be avoided
(insufficient data to assess other NSAIDs)
• If the patient is at moderate to high risk of a potential cardiovascular event and
treatment becomes necessary then initial management should be attempted initially
with acetaminophen then naproxen
51
Summary
• Food and Drug Administration – July 2015
• The risk of heart attack or stroke can occur as early as the first weeks of using an NSAID.
• The risk appears greater at higher doses.
• Newer information is not sufficient to determine that the risk of any particular NSAID is definitely
higher or lower than that of any other particular NSAID.
• NSAIDs can increase the risk of heart attack or stroke in patients with or without heart disease or risk
factors for heart disease.
• Patients treated with NSAIDs following a first heart attack were more likely to die in the first year after
the heart attack compared to patients who were not treated with NSAIDs after their first heart attack.
• There is an increased risk of heart failure with NSAID use.
52
Questions and Answers
•
Do NSAIDs increase cardiovascular risk in those with and without a history of known cardiovascular disease?
•
•
Are there any NSAIDs that confer less risk of cardiovascular events?
•
•
Naproxen seems through most analyses to confer the lowest risk, particularly when used for short durations, especially in those without history of
cardiovascular disease
What settings should NSAID use be considered contra-indicated from a primarily cardiovascular standpoint?
•
•
Both selective and nonselective NSAID use is associated with increased risk of cardiovascular events such as ischemic cardiovascular disease and
heart failure. This effect all in drugs seems to be both dose and time dependent.
For the treatment of peri-operative pain in the setting of coronary artery bypass grafting, recent myocardial infarction and in those patients with
known heart failure
Are there any other settings where NSAID use should be avoided from a cardio-protective standpoint?
•
In patients taking low dose aspirin for cardio-protection long term NSAID use should be avoided as their use may attenuate this benefit
•
Ibuprofen in particular should always be avoided in this setting
