[Pharmaca Induced Cardiac Injury]

Area of Science:

• Pharmacology
• Cardiology
• Toxicology

Context:

• Drugs modulate autonomic nervous system functions (sympathetic and parasympathetic).
• Drug metabolism can generate reactive species, directly damaging cardiomyocytes.
• Cardiac adverse drug reactions (ADR) manifest as arrhythmias, negative inotropy, and reduced myocardial perfusion.

Purpose:

• To highlight the underappreciated significance of cardiac ADRs.
• To emphasize the risks associated with pharmacodynamic drug-drug interactions.
• To introduce resources for identifying and managing drug-induced cardiac risks.

Summary:

• Cardiac ADRs stem from autonomic nervous system effects, hypersensitivity, or drug metabolism byproducts.
• These reactions can cause significant cardiac dysfunction, often masked by similar drug profiles across indications.
• Polypharmacy increases the risk of additive pharmacodynamic drug-drug interactions affecting cardiac function.

Impact:

• Increased awareness of cardiac ADRs can improve patient safety.
• Utilizing drug interaction databases and therapeutic drug monitoring aids in personalized and safer prescribing.
• Proactive identification and management of cardiac drug risks are essential in clinical practice.
