Several Drugs Prescribed for CHF
Congestive heart failure (CHF) is a term used to describe an impaired
ability of the heart to circulate blood to support the needs of tissues and
organs. Excessive workload on the heart due to increased systolic blood
pressure and increased diastolic volume contribute to this condition.
Typically, heart failure begins in the left heart ventricle, the main pumping
chamber. Ultimately, systolic function of the heart declines and diastolic
pressure increases. Coronary artery disease, acute myocardial infarction,
hypertension, alcohol abuse, or an infection may lead to this
condition, or the cause may be unknown. Although persons affected by
CHF initially do not experience symptoms, the ability to exercise is eventually
reduced, as the body is unable to support the increased demands
of exercise.
There are many medications available for the treatment of CHF. Diuretics,
such as bumetanide (Bumex) and furosemide (Lasix), work to
increase excretion of sodium and water, reducing volume and congestion
and leading to improvements in symptoms. Digoxin (Lanoxin) improves
symptoms by increasing heart muscle contractions. Vasodilators, such
as angiotensin-converting enzyme inhibitors, angiotensin receptor
blockers, and beta blockers, also may be prescribed.
