Insights

Potential COVID-19 treatments may pose cardiovascular risks. This review examines the cardiac conduction effects of antiviral and immunomodulatory drugs being investigated for Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) treatment.

Area of Science:

  • Cardiology
  • Infectious Diseases
  • Pharmacology

Background:

  • Coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2, impacts multiple organ systems, including the cardiovascular system.
  • Direct viral injury and the ensuing cytokine storm contribute to significant cardiovascular damage.
  • Effective anti-SARS-CoV-2 treatments are crucial for epidemic control.

Purpose of the Study:

  • To review the potential cardiovascular risks associated with emerging anti-SARS-CoV-2 therapies.
  • To specifically examine the impact of these drugs on cardiac conduction.
  • To inform clinical decision-making regarding treatment safety.

Main Methods:

  • Literature review of candidate anti-SARS-CoV-2 drugs.
  • Analysis of studies investigating drug effects on cardiovascular parameters.
  • Focus on drugs with antiviral and immunomodulatory mechanisms.

Main Results:

  • Candidate drugs, including antivirals and immunomodulators, are under investigation.
  • These treatments may present risks to cardiovascular health.
  • Alterations in cardiac conduction are a significant concern.

Conclusions:

  • Careful consideration of cardiovascular risks is necessary when selecting anti-COVID-19 treatments.
  • Further research is needed to fully elucidate the cardiac safety profile of these drugs.
  • Balancing therapeutic benefits against potential cardiac adverse effects is paramount.

Cardiovascular Drugs: Classification based on Therapeutic Indications

Cardiovascular diseases, encompassing a range of conditions, can significantly affect the heart's operations and the overall circulatory system. These conditions impair the heart's ability to pump blood, leading to a deficit in oxygen supply to crucial organs. Anomalies in the heart's electrical system, known as arrhythmias, can cause heartbeats to accelerate or slow down. Usually, heart rates increase during physical activity and decrease while resting or sleeping. However,...

Antiarrhythmic Drugs: Class II Agents as β-Adrenergic Blockers

Adrenergic stimulation generally impacts cardiac rate and rhythm. Specifically, stimulation of the β-adrenoceptors triggers an increase in intracellular calcium ion influx and pacemaker currents, which may cause arrhythmias. Catecholamines like adrenaline also demonstrate β2-adrenoceptor-mediated hypokalemia, impacting cardiac action potential and disrupting the normal cardiac rhythm. Class II antiarrhythmic drugs are β-adrenoceptor antagonists or β-blockers, which...

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-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,...

Antianginal Drugs: Calcium Channel Blockers and Ranolazine

Angina pectoris, a primary symptom of ischemic heart disease, requires careful pharmacological interventions. In this context, calcium channel blockers (CCBs) and ranolazine have emerged as crucial pharmacotherapeutic agents, providing deep insights into the complexities of angina management.
CCBs, a diverse class that includes dihydropyridines (nifedipine) and diphenylalkylamines (verapamil and diltiazem), exert their effect by blocking calcium channels in cardiac and smooth muscle cells. This...

Antiarrhythmic Drugs: Class IV Agents as Calcium Channel Blockers01:20

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...
