Final answer:
Drug-induced LQTS has various risk factors, including underlying heart conditions, medications, electrolyte imbalances, genetic predisposition, and impaired drug metabolism due to liver or kidney disease.
Step-by-step explanation:
Risk factors for drug-induced Long QT Syndrome (LQTS) comprise several factors that make certain individuals more susceptible to developing this condition when exposed to particular drugs. LQTS can lead to cardiac arrest, although it is not the same as myocardial infarction (MI). Some common risk factors for MI, a separate cardiac condition, include cardiovascular disease, smoking, and high LDL cholesterol. However, it's important to note that the risk factors specific for drug-induced LQTS may include underlying heart conditions, other medications that the patient is taking which may prolong the QT interval, electrolyte imbalances, such as low potassium or magnesium, genetic predisposition, liver or kidney disease which can affect drug metabolism, and the presence of other health conditions.
