Risk factors for doxorubicin-induced congestive heart failure
Annals of Internal Medicine
|November 1, 1979
Summary
Doxorubicin dose and patient age increase congestive heart failure risk. A weekly schedule significantly lowers this risk compared to a 3-week schedule, aiding clinical decisions.
Area of Science:
- Cardiology
- Oncology
- Pharmacology
Background:
- Doxorubicin is a widely used chemotherapy agent.
- Congestive heart failure is a known, serious side effect of doxorubicin therapy.
- Identifying risk factors is crucial for patient management.
Purpose of the Study:
- To identify potential risk factors for doxorubicin-induced congestive heart failure.
- To analyze the relationship between doxorubicin dosage, administration schedule, and heart failure incidence.
- To inform clinical practice regarding doxorubicin use.
Main Methods:
- Retrospective analysis of 4018 patient records.
- Examination of overall incidence of drug-induced congestive heart failure.
- Correlation analysis of risk factors including total dose, schedule, age, performance status, sex, race, and tumor type.
Main Results:
- Overall incidence of doxorubicin-induced congestive heart failure was 2.2%.
- Increased risk was associated with higher cumulative doxorubicin doses and advancing patient age.
- A weekly doxorubicin schedule showed a significantly lower incidence of heart failure compared to the every 3-week schedule.
Conclusions:
- Doxorubicin dose and patient age are significant risk factors for congestive heart failure.
- Weekly administration of doxorubicin may reduce cardiotoxicity.
- Findings support better risk-benefit assessment and development of safer anthracycline analogues.

Drug Toxicity: Risk factors
133
Adverse Drug Reactions (ADRs) are potential complications that arise during pharmacotherapy, influenced by multiple risk factors. Age plays a significant role; both neonates and the elderly are at heightened risk due to their respective immature and diminished metabolic and elimination processes. Gender also impacts ADRs, with females experiencing a 1.5 to 1.7-fold greater risk than males, which may be linked to pharmacokinetic, pharmacodynamic, and hormonal differences. Notably, neonates, the...

Heart Failure I: Introduction
1.2K
Heart failure refers to a clinical syndrome caused by structural or functional cardiac disorders that prevent the heart from pumping an adequate amount of blood to meet the body's metabolic needs. This condition often arises from myocardial infarction or ischemia, leading to decreased cardiac output, reduced tissue perfusion, impaired gas exchange, fluid volume imbalance, and decreased functional ability.Heart failure can result from disruptions in the mechanisms that regulate cardiac output...

Imbalances in Cardiac Output
3.4K
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...

Heart Failure Drugs: Inotropic Agents
1.8K
Positive inotropic agents are commonly used as the first line of treatment for heart failure. One such agent is digoxin, derived from the genus Digitalis, which has been known for centuries but effectively utilized since 1785. However, these cardiac glycosides can have potentially toxic effects due to their mechanism of action, which involves inhibiting Na+/K+-ATPase and increasing contractility. Digoxin is absorbed orally and distributed in various tissues, including the CNS. It has a long...

Pathophysiology of Heart Failure
4.5K
Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

Heart Failure Drugs: Diuretics

Heart failure and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...
