Ivabradine, sold under the brand name Procoralan among others, is a medication, which is a pacemaker current (If) inhibitor, used for the symptomatic management of heart-related chest pain and heart failure. Patients who qualify for use of Ivabradine for coronary heart failure are patients who have symptomatic heart failure, with reduced ejection volume, and heart rate at least 70 bpm, and the condition not able to be fully managed by beta blockers. [2]

Contents

Ivabradine acts by allowing negative chronotropy in the sinoatrial structure, thus reducing the heart rate via specific inhibition of the pacemaker current. It operates by a mechanism different from that of beta blockers and calcium channel blockers, which are two commonly prescribed antianginal classes of cardiac drugs. Ivabradine has no apparent inotropic properties and may be a cardiotonic agent.

Medical uses

It is used for the symptomatic treatment of chronic stable angina pectoris in patients with normal sinus rhythm who cannot take beta blockers. It is also being used off-label in the treatment of inappropriate sinus tachycardia (IST). [3] Ivabradine stands as a pharmacological option for controlling HR and rhythm without associated side effects in postoperative CABG patients with IST. [4]

Chest pain

Ivabradine is as effective as the beta blocker atenolol and comparable with amlodipine in the management of chronic stable angina, as demonstrated by improvements in total exercise duration in non-inferiority trials, hence it can be an alternative therapy for those who cannot tolerate conventional therapies. [5] [6] In people not sufficiently managed with beta blockers for their angina, adding ivabradine can further reduce heart rate and improve total exercise duration. [7]

Heart failure

It is used in combination with beta blockers in people with heart failure with LVEF lower than 35 percent inadequately controlled by beta blockers alone and whose heart rate exceeds 70 beats per minute. [8] In people not sufficiently managed with beta blockers for their heart failure adding ivabradine decreases the risk of hospitalization for heart failure. [2]

Tachycardia

The clinical use of ivabradine is predicated on its mechanism of action on sinoatrial nodal tissue where it selectively inhibits the funny current (If) and results in a decrease in heart rate. [9]

Ivabradine’s most frequent application in electrophysiology is for the treatment of inappropriate sinus tachycardia. Its use for inappropriate sinus tachycardia is not a European Medicines Agency or Food and Drug Administration approved indication for ivabradine. [9]

It has been used experimentally for the treatment of postural orthostatic tachycardia syndrome in patients with long COVID. [10]

Contraindications

Ivabradine is contraindicated in sick sinus syndrome. It should also not be used concomitantly with potent inhibitors of CYP3A4, including azole antifungals (such as ketoconazole), macrolide antibiotics, nefazodone and the antiretroviral drugs nelfinavir and ritonavir. [11]

Use of ivabradine with verapamil or diltiazem is contraindicated. [12]

Adverse effects

Overall, 14.5% of patients taking ivabradine experience luminous phenomena (by patients described as sensations of enhanced brightness in a fully maintained visual field). This is probably due to blockage of Ih ion channels in the retina, which are very similar to cardiac If. These symptoms are mild, transient, and fully reversible. In clinical studies, about 1% of all patients had to discontinue the drug because of these sensations, which occurred on average 40 days after the drug was started. [5]

In a large clinical trial, bradycardia (unusually slow heart rate) occurred in 2% and 5% of patients taking ivabradine at doses of 7.5 and 10 mg respectively (compared to 4.3% in those taking atenolol). [5] Headaches were reported in 2.6 to 4.8 percent of cases. [5] Other common adverse drug reactions (1–10% of patients) include first-degree AV block, ventricular extrasystoles, dizziness and/or blurred vision. [13]

Mechanism of action

Ivabradine acts on the If (f is for "funny", so called because it had unusual properties compared with other current systems known at the time of its discovery) ion current, which is highly expressed in the sinoatrial node. If is a mixed Na+–K+ inward current activated by hyperpolarization and modulated by the autonomic nervous system. It is one of the most important ionic currents for regulating pacemaker activity in the sinoatrial (SA) node. Ivabradine selectively inhibits the pacemaker If current in a dose-dependent manner. Blocking this channel reduces cardiac pacemaker activity, selectively slowing the heart rate and allowing more time for blood to flow to the myocardium. [14] [15] By inhibiting the If channel, ivabradine reduces the heart rate and workload on the heart. This is relevant in the usage of the medication to treat angina as well as congestive heart failure. This is in contrast to other commonly used rate-reducing medications, such as beta-blockers and calcium channel blockers, which not only reduce heart rate, but also the cardiac contractility. Given the selective decrease in rate without loss of contractility, ivabradine may prove efficacious for treatment of congestive heart failure with reduced ejection fraction.

Ivabradine binds to HCN4 receptors (potassium/sodium hyperpolarization-activated cyclic nucleotide-gated channel 4), utilizing Y506, F509 and I510 residues. [16]

Clinical trials

Coronary artery disease

The BEAUTIFUL study randomised over 10917 patients having stable coronary artery disease and left ventricle dysfunction (ejection fraction < 40%). Ivabradine did not show a significant reduction in the primary composite endpoint of cardiovascular death, admission to hospital for acute myocardial infarction, and admission to hospital for new onset or worsening heart failure. However, in a prespecified subgroup of patients with a baseline heart rate of more than 70 bpm, ivabradine significantly reduced the following secondary endpoints: [17]

These results were seen in combination therapy with beta blockers, and were found to be safe and effective in improving coronary artery disease outcomes in patients with heart rates of 70 bpm or more. [18]

The SIGNIFY trial randomised 19102 patients with stable coronary artery disease and an elevated heart rate greater than 70 beats per minute were assigned to an intervention of ivabradine or placebo in addition to standard therapy. Ivabradine did not significantly improve the secondary outcomes in patient groups, however did demonstrate a reduction in heart rate. When compared to the SHIFT study, a reduction in cardiovascular death or hospital admission was also demonstrated and hence should be considered when additional therapy is in question. [19] [20]

Chronic heart failure

In the SHIFT study, ivabradine significantly reduced the risk of the primary composite endpoint of hospitalization for worsening heart failure or cardiovascular death by 18% (P<0.0001) compared with placebo on top of optimal therapy. [21] These benefits were observed after 3 months of treatment. SHIFT also showed that administration of ivabradine to heart failure patients significantly reduced the risk of death from heart failure by 26% (P=0.014) and hospitalization for heart failure by 26% (P<0.0001). The improvements in outcomes were observed throughout all prespecified subgroups: female and male, with or without beta-blockers at randomization, patients below and over 65 years of age, with heart failure of ischemic or non-ischemic etiology, NYHA class II or class III, IV, with or without diabetes, and with or without hypertension. [22] A 2020 Cochrane review found no difference in cardiovascular mortality and serious adverse events between long-term treatment with ivabradine and placebo/usual care/no treatment in participants with heart failure with a reduced ejection fraction. [23]

A note of caution must be emphasised. Ivabradine, though indicated for chronic heart failure in patients who are clinically stable, is not indicated in acute heart failure where the enhanced heart rate represents cardiac reserve. Indiscriminate use of Ivabradine could destabilise these patients.

Multifocal atrial tachycardia (MAT) is an abnormal heart rhythm, specifically a type of supraventricular tachycardia, that is particularly common in older people and is associated with exacerbations of chronic obstructive pulmonary disease (COPD). Normally, the heart rate is controlled by a cluster of cells called the sinoatrial node. When a number of different clusters of cells outside the SA node take over control of the heart rate, and the rate exceeds 100 beats per minute, this is called multifocal atrial tachycardia.

<span class="mw-page-title-main">Landiolol</span> Chemical compound

Landiolol (INN) is an ultra short-acting, β1-superselective intravenous adrenergic antagonist, which decreases the heart rate effectively with less negative effect on blood pressure or myocardial contractility. In comparison to other beta blockers, landiolol has the shortest elimination half-life, ultra-rapid onset of effect, and predictable effectiveness with inactive metabolites. The pure S-enantiomer structure of landiolol is believed to develop less hypotensive side effects in comparison to other β-blockers. This has a positive impact on the treatment of patients when reduction of heart rate without decrease in arterial blood pressure is desired. Landiolol was developed by modifying the chemical structure of esmolol to produce a compound with a higher rate of cardioselectivity and a greater potency without increasing its duration of action. It is sold as landiolol hydrochloride. Based on its positive benefit risk profile, landiolol has been granted the marketing authorization and introduced to the European markets under the brand names Rapibloc, Raploc, Runrapiq, Landibloc mid 2016. Landiolol is available in Japan under the brand names Onoact (50 mg) and Corbeta.

<span class="mw-page-title-main">Coronary ischemia</span> Medical condition

Coronary ischemia, myocardial ischemia, or cardiac ischemia, is a medical term for a reduced blood flow in the coronary circulation through the coronary arteries. Coronary ischemia is linked to heart disease, and heart attacks. Coronary arteries deliver oxygen-rich blood to the heart muscle. Reduced blood flow to the heart associated with coronary ischemia can result in inadequate oxygen supply to the heart muscle. When oxygen supply to the heart is unable to keep up with oxygen demand from the muscle, the result is the characteristic symptoms of coronary ischemia, the most common of which is chest pain. Chest pain due to coronary ischemia commonly radiates to the arm or neck. Certain individuals such as women, diabetics, and the elderly may present with more varied symptoms. If blood flow through the coronary arteries is stopped completely, cardiac muscle cells may die, known as a myocardial infarction, or heart attack.

<span class="mw-page-title-main">Acute decompensated heart failure</span> Medical condition

Acute decompensated heart failure (ADHF) is a sudden worsening of the signs and symptoms of heart failure, which typically includes difficulty breathing (dyspnea), leg or feet swelling, and fatigue. ADHF is a common and potentially serious cause of acute respiratory distress. The condition is caused by severe congestion of multiple organs by fluid that is inadequately circulated by the failing heart. An attack of decompensation can be caused by underlying medical illness, such as myocardial infarction, an abnormal heart rhythm, infection, or thyroid disease.

Atrial tachycardia is a type of heart rhythm problem in which the heart's electrical impulse comes from an ectopic pacemaker in the upper chambers (atria) of the heart, rather than from the sinoatrial node, the normal origin of the heart's electrical activity. As with any other form of tachycardia, the underlying mechanism can be either the rapid discharge of an abnormal focus, the presence of a ring of cardiac tissue that gives rise to a circle movement (reentry), or a triggered rapid rhythm due to other pathological circumstances.
