Insights

Clevidipine effectively and safely lowers high blood pressure in patients with acute heart failure (AHF). This ultra-short-acting calcium channel blocker achieved target blood pressure without causing hypotension in AHF patients.

Area of Science:

  • Cardiology
  • Pharmacology

Background:

  • Acute severe hypertension is common in acute heart failure (AHF) patients.
  • Clevidipine, a dihydropyridine calcium channel blocker, is a potential treatment option.

Purpose of the Study:

  • To evaluate the efficacy and safety of clevidipine in AHF patients with severe hypertension.
  • To assess the time to reach the target blood pressure range and the incidence of hypotension.

Main Methods:

  • A post hoc subgroup analysis of the VELOCITY trial involving 19 AHF patients.
  • Patients received clevidipine to achieve a prespecified systolic blood pressure target range (ITR) within 30 minutes.

Main Results:

  • Median time to reach ITR was 11.3 minutes; 94% achieved ITR within 30 minutes.
  • No patients experienced hypotension below the ITR; heart rate remained stable.
  • Mean systolic blood pressure reduction was 50 mm Hg (25%) after 18 hours of continuous infusion.

Conclusions:

  • Clevidipine is safe, well-tolerated, and efficacious for managing hypertension in AHF patients.
  • It safely decreases systolic blood pressure without causing unexpected hypotension.

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...

Heart Failure Drugs: Diuretics

Heart failure and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...

Heart Failure Drugs: Inotropic Agents

Positive inotropic agents are commonly used as the first line of treatment for heart failure. One such agent is digoxin, derived from the genus Digitalis, which has been known for centuries but effectively utilized since 1785. However, these cardiac glycosides can have potentially toxic effects due to their mechanism of action, which involves inhibiting Na+/K+-ATPase and increasing contractility. Digoxin is absorbed orally and distributed in various tissues, including the CNS. It has a long...
Antihypertensive Drugs: Potassium-Sparing Diuretics01:28

Antihypertensive Drugs: Potassium-Sparing Diuretics

Liddle syndrome is a genetically inherited form of hypertension characterized by the overactivity of epithelial sodium channels in the nephron, the functional unit of the kidney. This heightened activity leads to increased sodium reabsorption and excessive excretion of potassium. To counteract this, potassium-sparing diuretics such as amiloride are used. They function by blocking these sodium channels, thereby reducing the influx of sodium into the epithelial cells and minimizing the loss of...
Heart Failure Drugs: Inhibitors of Renin-Angiotensin System01:26

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...
Heart Failure Drugs: β-Blockers01:22

Heart Failure Drugs: β-Blockers

β-adrenergic antagonists, commonly known as β-blockers, block the effects of sympathetic neurotransmitters such as noradrenaline (NA) and adrenaline (ADR). They have several beneficial effects in heart failure treatment. They reduce heart rate, the force of contraction, and cardiac muscle relaxation. They also slow the atrial-ventricular conduction rate and raise the threshold for arrhythmias. The concentration of β-blockers determines their effects on bronchodilation, vasodilation, and...
