A meta-analysis of 19 randomized trials found COX-2 inhibitors significantly associated with blood pressure elevation compared to NSAIDs and placebos. This increased risk may be clinically significant for patients at elevated cardiovascular risk, particularly in the elderly population.
Researchers have identified two genomic regions associated with hypertension in African Americans, which can help locate genes affecting the condition. The study uses a genome-wide scan to compare genetic variations between African and European populations.
Alcohol contributes significantly to global health, with 4% of the global burden attributed to it. Raising prices and reducing availability can lower consumption and mortality rates. However, ineffective policies hinder progress in controlling excessive drinking.
Recent studies on COX-2 inhibitors have found that celecoxib may not increase blood pressure, while rofecoxib does, and that these drugs are safe for patients with type 2 diabetes. However, patients taking warfarin with COX-2 inhibitors or NSAIDs have an increased risk of upper gastrointestinal hemorrhage.

A study led by Mount Sinai School of Medicine researchers found that imidazole-4-acetic acid-ribotide may be a primary cause of high blood pressure and a molecular link to diabetes. The molecule binds to receptors in the brain, leading to elevated blood pressure, which can also impair insulin release.
Yale researchers found strong clinical evidence to support treating systolic blood pressure of at least 160 mm Hg in older adults. Treatment decisions should prioritize patient preferences and tolerance of therapy due to limited evidence on benefits.
Studies found strong evidence supporting treatment of systolic hypertension in older persons with SBP of at least 160 mm Hg. Treatment guidelines recommend thiazide diuretics and long-acting calcium channel blockers as first-line therapy for SH. Despite effectiveness, poor control of SH among patients is increasing.
