NSAIDs may impair renal function in patients with a decreased effective circulating volume by inhibiting prostaglandin synthesis.

Consequently, water and sodium retention, and decreases in renal blood flow and glomerular filtration rate may occur, affecting the unstable cardiovascular homeostasis in these patients. In patients with pre-existing heart failure, this may lead to cardiac decompensation. The same study highlighted the differences between various coxibs. Significant increases in blood pressure were found with rofecoxib and etoricoxib, while the effect of celecoxib on blood pressure appeared to be minimal.

The risk of NSAID-mediated BP increase in patients with pharmacologically controlled hypertension also depends on the antihypertensive drug used by the patient. The effect of beta-blockers and various renin-angiotensin-aldosterone system RAAS inhibitors seems to be influenced the most [ 40 , 42 ].

The most likely reason is that NSAIDs under normal circumstances inhibit the production of renin as a compensatory mechanism for the retention of water and sodium caused by them and also by direct COX-2 inhibition. If RAAS is inhibited chronically by the antihypertensive regimen used by the patient, the previously described compensatory mechanism can't help to avoid an increase in the blood pressure [ 43 ]. Most patients with severe rheumatoid arthritis and osteoarthritis are elderly and often have multiple co-morbidities, including hypertension treated with antihypertensive drugs.

Under these circumstances the safe and effective treatment of their symptoms is problematic [ 44 ]. In a pilot study by Varga, et al. Inhibition of prostanoid production in the kidney may reduce glomerular filtration and excretion of sodium and water. NSAIDs are therefore associated with risk of hypervolemia and worsening heart failure.

The study by Heerdink, et al. The authors did not find a significant difference between individual NSAIDs, which suggests a class effect. The highest risk of heart failure decompensation was present within the first days of treatment initiation and gradually decreased to the level of placebo after a month. NSAID users were found to have a relative risk of 2. In patients with established CV disease, the RR was noticeably higher Mamdani, et al.

The relative risk in users of non-selective agents was 1. Celecoxib was not associated with increased risk. The level of risk displays a large variability between individual drugs in the group and seems to be affected by the baseline cardiovascular risk of patients, although CV ADRs can develop even in individuals without a pre-existing CV condition. It appears that the absolute degree of COX-2 inhibition and not COX-2 selectivity is responsible for the increased risk.

Differences in pharmacokinetics might also play a role. Patients with congestive heart failure are at risk of the disease decompensation while taking NSAIDs.

The risk is highest in patients taking diuretics, especially during the first few weeks of NSAID treatment. In conclusion, it should be stressed that candidates for long-term administration of NSAIDs are commonly elderly patients, who often suffer from arterial hypertension, CHF and coronary artery disease. Adequate monitoring for signs and symptoms of adverse effects with proper patient education are required to increase patient safety during NSAID therapy. The duration of NSAID treatment should be limited as much as the clinical situation allows and only the minimal effective dose should be used.

Keywords: non-steroidal anti-inflammatory drugs, cardiovascular risk, adverse effect, cardiovascular event, arterial hypertension, heart failure.

Non-selective COX-1 and COX-2 inhibitors: acetylsalicylic acid, ibuprofen, diclofenac, ketoprofen, indomethacin, naproxen Preferential COX-2 inhibitors: meloxicam, nimesulide, etodolac Selective COX-2 inhibitors: celecoxib, rofecoxib, etoricoxib, valdecoxib. Open in a separate window. Gastrointestinal erosions and ulcers of gastric mucosa, nausea, vomiting, bloating, diarrhea, constipation Renal reduced glomerular filtration rate, Na and water retention, pitting edema, hyperkalemia, kidney failure, interstitial nephritis Cardiovascular thrombotic events, increased blood pressure, congestive heart failure, palpitations Central nervous system headache, fatigue, insomnia, vertigo, seizures Other bleeding, asthma attacks, Reye's syndrome, urticaria, neutropenia.

Thrombotic events After introduction of the first coxibs to clinical practice, multiple large, randomized clinical trials were organized to assess their gastrointestinal tolerability. Table 3 Overview of the results of Trelle, et al.

Table 5 Relative risk of cardiovascular events with preferential and selective COX-2 inhibitors compared to controls in a meta-analysis McGettigan and Henry. Possible mechanisms for the increased risk of thrombotic events The first theory trying to explain the risk of thrombotic events of selective COX-2 inhibitors was based on the assumption that COX-2 in the vessel wall was an important source of prostacyclin, whereas COX-1 was responsible for the production of thromboxane in platelets.

Increase in arterial blood pressure NSAIDs can cause sodium and water retention, as well as reduce formation of the vasodilator prostacyclin in the vessel wall.

Heart failure Inhibition of prostanoid production in the kidney may reduce glomerular filtration and excretion of sodium and water. Footnotes The authors have declared that no competing interests exist.
