Insights

Verapamil improved congestive heart failure (CHF) and exercise tolerance in elderly patients with diastolic dysfunction. This treatment enhanced left ventricular (LV) diastolic function, offering a potential therapeutic benefit.

Area of Science:

  • Cardiology
  • Geriatrics
  • Pharmacology

Background:

  • Elderly patients with preserved left ventricular (LV) systolic function often experience diastolic dysfunction, leading to congestive heart failure (CHF).
  • Assessing and improving LV diastolic function is crucial for managing CHF in this population.

Purpose of the Study:

  • To evaluate the effect of verapamil on left ventricular (LV) diastolic function in elderly patients with CHF.
  • To determine if verapamil improves clinical symptoms and exercise capacity in patients with diastolic dysfunction.

Main Methods:

  • A randomized, placebo-controlled crossover study involving 15 elderly patients with CHF (NYHA class II-III) and normal LV systolic function.
  • Verapamil (120 mg daily) or placebo was administered for three months, with a one-week washout period.
  • Assessments included congestive heart failure (CHF) score, treadmill exercise test, and Doppler echocardiography.

Main Results:

  • Verapamil significantly improved CHF scores and increased exercise time compared to placebo.
  • Doppler echocardiography revealed significant improvements in LV diastolic function with verapamil, including increased mitral A wave duration/pulmonary venous atrial systolic reversal duration and decreased isovolumic relaxation time.
  • Verapamil did not alter blood pressure, heart rate, LV ejection fraction, LV mass, or cardiac output.

Conclusions:

  • Three months of verapamil treatment can effectively improve congestive heart failure (CHF) symptoms, enhance exercise tolerance, and improve left ventricular (LV) diastolic function in elderly patients.
  • Verapamil is a potential therapeutic option for elderly patients with diastolic dysfunction contributing to CHF.

Antiarrhythmic Drugs: Class IV Agents as Calcium Channel Blockers

Class IV antiarrhythmic drugs, such as verapamil and diltiazem, block calcium channels. They primarily affect the heart, slowing the conduction in calcium-dependent tissues like the SA and AV nodes. These drugs manage reentrant supraventricular tachycardia (SVT) and reduce ventricular rate in atrial flutter/fibrillation.
Verapamil, a calcium channel blocker, inhibits calcium movement across myocardial cell membranes and vascular smooth muscle. This results in the dilation of coronary and...

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...
Imbalances in Cardiac Output01:26

Imbalances in Cardiac Output

The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send blood...
Mitral Regurgitation I: Introduction01:20

Mitral Regurgitation I: Introduction

Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...

Heart Failure II: Pathophysiology

Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

Cardiomyopathy II: Dilated Cardiomyopathy

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...
