Insights

Perindopril treatment increased plasma levels of Thrombospondin-1 (TSP-1) in hypertensive patients with endothelial dysfunction. This finding highlights TSP-1 as a biomarker for Perindopril

Area of Science:

  • Cardiovascular Research
  • Pharmacology
  • Biomarker Discovery

Background:

  • Thrombospondin-1 (TSP-1) is an angiogenesis inhibitor with complex roles in cardiovascular disorders (CVDs).
  • Its precise function in CVD physiopathology is not fully understood, potentially due to its multiple cellular interactions.
  • TSP-1 influences NO-mediated signaling, angiogenesis, tissue perfusion, and endothelial cell proliferation.

Purpose of the Study:

  • To quantify the effect of Perindopril on plasma TSP-1 levels in hypertensive patients with endothelial dysfunction.
  • To compare Perindopril's effect on TSP-1 with other antihypertensive drugs (beta-blockers, calcium channel blockers, diuretics).

Main Methods:

  • A comparative study involving hypertensive patients with endothelial dysfunction undergoing chronic treatment.
  • Quantification of plasma TSP-1 levels in patients treated with Perindopril, other antihypertensives, and a control group.

Main Results:

  • Patients treated with Perindopril exhibited significantly increased plasma TSP-1 levels.
  • TSP-1 levels in the Perindopril group were higher compared to both other hypertensive patients and the control group.

Conclusions:

  • Perindopril treatment leads to elevated plasma TSP-1 levels in hypertensive patients with endothelial dysfunction.
  • This suggests TSP-1 as a biomarker reflecting the pleiotropic, anti-proliferative, and anti-inflammatory effects of Perindopril.

Antihypertensive Drugs: Angiotensin-Converting Enzyme Inhibitors

Angiotensin-converting enzyme (ACE), a vital component of the renin-angiotensin-aldosterone system, is abundant in lung endothelial cells. ACE converts the inactive decapeptide, angiotensin I, into the active octapeptide, angiotensin II. This potent vasoconstrictor narrows blood vessels, increasing resistance to blood flow and elevating blood pressure. Angiotensin II also stimulates aldosterone production, encouraging kidney cells to reabsorb more sodium and water from urine, thereby increasing...

Treatment for Pulmonary Arterial Hypertension: Endothelin Receptor Antagonists

Endothelins (ETs) are potent vasoactive peptides critical in the human body's various physiological and pathological processes. One of the most promising therapeutic strategies for treating pulmonary arterial hypertension (PAH) involves counteracting the effects of these endothelins using a class of drugs known as endothelin receptor antagonists.
ETs are synthesized through a complex sequence of enzymatic steps, primarily involving an enzyme referred to as endothelin-converting enzyme...

Antihypertensive Drugs: Angiotensin II Receptor Blockers

In the renin-angiotensin-aldosterone system, a hormone called angiotensin II plays a crucial role. It binds to the AT1 receptors in vascular smooth muscles coupled with Gq proteins. The activation of these receptors activates an enzyme called phospholipase C, which releases two molecules: inositol trisphosphate and diacylglycerol. These molecules cause a chain reaction that leads to the phosphorylation of myosin light chains and promotes interaction between actin and myosin, leading to smooth...

Antihypertensive Drugs: Direct Renin Inhibitors

The renin-angiotensin-aldosterone system (RAAS) is an intricate physiological pathway involving numerous enzymes and hormones, including renin, angiotensin-converting enzyme (ACE), angiotensin I and II, and aldosterone. Imbalances within this system increase the production of angiotensin II and aldosterone. Increased angiotensin II levels promote vasoconstriction and blood pressure elevation. Concurrently, higher aldosterone levels stimulate sodium and water reabsorption in the kidneys,...

Antihypertensive Drugs: Vasodilators

Vasodilators, primarily affecting the smooth muscles within arterial and venous walls, are commonly used for hypertension treatment. Medications such as minoxidil and hydralazine primarily target arteries and arterioles, while sodium nitroprusside acts on arterioles and venules. Minoxidil, functioning as a prodrug, is metabolized by hepatic sulfotransferase into its active form, minoxidil sulfate, after oral administration. This metabolite binds to the sulfonylurea receptor (SUR) component of...

Hypertension II: Pathophysiology

Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...
