This antiplatelet agent exerts its effect through direct inhibition of adenosine diphosphate (ADP) binding to its receptor and of the subsequent ADP-mediated activation of the lipoprotein GPIIb/IIIa complex.
A meta-analysis of data from randomized, parallel-designed, placebo-controlled studies involving >44,000 patients demonstrated that those who had taken the cycloxygenase-2 (COX-2) inhibitor celecoxib (50–800 mg TDD) had a lower incidence of adverse cardiorenal events including hypertension, edema, or congestive heart failure than those taking nonselective non-steroidal anti-inflammatory drugs (NSAIDs), according to an oral and poster presentation at the 21st annual scientific meeting of the American Society of Hypertension (ASH) in New York, NY.
While the increased risk of vascular events associated with cyclooxygenase-2 (COX-2) inhibitors has been well established, new data are emerging that demonstrate similar risk increases associated with non-steroidal anti-inflammatory drugs (NSAIDs) that are not selective for COX-2. The data, published in the British Medical Journal (BMJ), were from a meta-analysis of published and unpublished randomized trials. The study comes more than a year after the withdrawals of the COX-2-selective NSAIDs rofecoxib and valdecoxib from the US market.
A meta-analysis of data from national hospital records in Denmark and from the country's national prescription registry showed that the use of selective cyclooxygenase-2 (COX-2) inhibitors in all doses and nonselective non-steroidal anti-inflammatory drugs (NSAIDs) in high doses raised the risk of death in patients who experienced first-time acute myocardial infarction (MI).
An observational cohort study found that the risk of major congenital malformations for infants who were exposed to angiotensin-converting enzyme (ACE) inhibitors during their first trimester increased by a factor of more than 2, while exposure to other antihypertensive medications did not demonstrate an increased risk.
A cohort study with a nested case-control analysis of first hospitalizations for heart failure (HF) associated the use of non-steroidal anti-inflammatory drugs (NSAIDs) with a 30% increase in the target end point among patients aged 60 to 84 years.
Phase 3 clinical trials demonstrated that the once-daily, highly selective beta blocker nebivolol lowers blood pressure in a dose-dependent manner and is well tolerated at all doses, according to presenters at the 21st annual scientific meeting of the American Society of Hypertension (ASH), in New York, NY.
A review of agents in late-stage development for the treatment of atherosclerosis and thrombosis (June 2006).
Angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) play a role in the treatment of hypertension (HTN) and heart failure (HF). The literature shows that in patients with HTN with comorbidities, such as HF, myocardial infarction (MI), diabetes mellitus, chronic kidney disease, and stroke, ACE inhibitors and ARBs appear to provide added benefit beyond solely lowering blood pressure. In addition, clinical trials have also demonstrated that ACE inhibitors and ARBs may be beneficial in the prevention of diabetes, atrial fibrillation (AF), and recurrent stroke. This review evaluates the practice guidelines and current literature to assess the implications for the use of ACE inhibitors or ARBs in HTN and HF.
The 55th Annual Scientific Session of the American College of Cardiology (ACC) assembled from March 11 to March 14, 2006, in Atlanta, Ga, to exchange new and continuing research in cardiovascular disease. The program featured more than 1,600 oral and poster presentations of original research and hundreds of invited lectures and interactive sessions, with many offering the opportunity to update attendees' knowledge of available and investigational pharmaceuticals.
Aspirin is the cornerstone of therapy in the treatment and prevention of cardiovascular disease. The potential benefit of aspirin therapy may be significantly reduced in patients with aspirin resistance, creating a clinical and economic burden on the healthcare system. The purpose of this article is to clarify the term "aspirin resistance," describe the proposed mechanisms, review the clinical outcome studies with associated resistance testing, and discuss the potential pharmacologic management of this problem. Literature searches were performed using MEDLINE (January 1966 to January 2006) for review articles on aspirin resistance and antiplatelet activity. Aspirin's primary mechanism of action is to irreversibly inhibit cyclooxygenase-1 (COX-1); however, there are reports of alternative biochemical pathways producing platelet aggregation. The addition of thienopyridines to aspirin should be considered for the management of aspirin-resistant patients. (Formulary. 2006;41:192–201.)
Topiramate safely decreases body mass, hypertension. Topiramate reduces body weight and blood pressure with generally mild-to-moderate adverse effects, according to a randomized, placebo-controlled trial involving obese subjects with hypertension.
A recent meta-analysis published in the Journal of the American Medical Association (JAMA) found that statins have no effect on cancer risk. The finding is in contrast with at least 7 retrospective analyses that suggest that statins reduce the risk of developing cancer.
The serine protease inhibitor aprotinin (Trasylol, Bayer) may increase the risk of renal failure, myocardial infarction, heart failure, stroke, and encephalopathy among patients undergoing coronary artery bypass graft (CABG) surgery, according to an observational study in the New England Journal of Medicine (NEJM).
Beta blockers, touted for 3 decades as first-line drugs in the treatment of hypertension, are less than optimum in comparison to other antihypertensive drugs and raise the risk of stroke, according to a meta-analysis published online by The Lancet.
Early invasive strategy, recommended by the current guidelines in the treatment of patients with acute coronary syndromes (ACS), did not excel when compared with its more conservative alternative in a randomized study published in the New England Journal of Medicine.
Utilizing statin therapy, researchers have provided further evidence that absolute reductions in LDL-C reduce the incidence of coronary heart disease (CHD) and other major vascular events.
