Abstract

Insights

Non-steroidal anti-inflammatory drugs (NSAIDs) may increase cardiovascular thrombotic event risk, particularly with long-term use of high-dose drugs like rofecoxib and diclofenac. Naproxen appears safer, with most NSAIDs showing a risk ratio below 2.

Area of Science:

  • Pharmacology
  • Cardiovascular Medicine
  • Epidemiology

Background:

  • NSAIDs, particularly rofecoxib, are linked to increased cardiovascular thrombotic events.
  • Risk is associated with COX-2 inhibitory potency, with naproxen being an exception.
  • Hypotheses include prostacyclin/thromboxane imbalance and COX-2-mediated hypertension.

Purpose of the Study:

  • To evaluate the cardiovascular risk associated with NSAID use.
  • To analyze data from clinical trials and observational studies on NSAID cardiovascular safety.

Main Methods:

  • Systematic review of clinical trials and observational studies.
  • Inclusion criteria: studies with follow-up of at least 6 months.
  • Analysis of cardiovascular risk data for various NSAIDs.

Main Results:

  • Ambiguous results regarding long-term NSAID exposure and cardiovascular risk.
  • Increased risk of myocardial infarction or stroke noted with high-dose rofecoxib and possibly diclofenac.
  • Limited risk increase with shorter NSAID exposure (under 30 days) and most other NSAIDs (risk ratio < 2).

Conclusions:

  • Long-term NSAID use, especially high-dose rofecoxib and diclofenac, may elevate cardiovascular risk.
  • Most NSAIDs show a low relative risk, particularly for short-term use.
  • Further research is needed to clarify risks associated with long-term use of most NSAIDs.

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System

The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...

Cardiovascular Drugs: Classification based on Therapeutic Indications

Cardiovascular diseases, encompassing a range of conditions, can significantly affect the heart's operations and the overall circulatory system. These conditions impair the heart's ability to pump blood, leading to a deficit in oxygen supply to crucial organs. Anomalies in the heart's electrical system, known as arrhythmias, can cause heartbeats to accelerate or slow down. Usually, heart rates increase during physical activity and decrease while resting or sleeping. However,...
