Key result
Essential hypertension is linked to ~52% higher β-thromboglobulin versus normotensive controls, indicating enhanced platelet activation.
Why the study?
Platelet function and prostanoid imbalance in essential hypertension and their modulation by antihypertensive therapy were not fully characterized.
Are platelet function and prostanoid levels altered in essential hypertension, and does antihypertensive therapy affect them?
Population
51 patients with uncomplicated essential hypertension and 44 age-matched normotensive controls
Comparison
Hypertensive patients vs normotensive controls; before and after antihypertensive therapy
Design
Cross-sectional study

May indicate platelet activation in hypertension; leaves open prognostic value and therapeutic implications.
Cross-Sectional (n=95)
Are platelet function and prostanoid levels altered in essential hypertension, and does antihypertensive therapy affect them?
Absolute Event Rate: 57.9% vs 38.1%
p-value: p=<0.02
Essential hypertension is associated with enhanced platelet function and imbalanced prostaglandin production, which may be partially reversed by antihypertensive therapy.
Kenji Sato (1987) conducted a cross-sectional in Essential hypertension (n=95). Essential hypertension vs. Normotensive controls was evaluated on Plasma beta-thromboglobulin (β-TG) concentration (p=<0.02). Patients with essential hypertension had significantly higher plasma levels of β-thromboglobulin (57.9 vs 38.1 ng/ml, p<0.02) and platelet factor 4 compared to normotensive controls, indicating enhanced platelet activation.
