Similarities and Differences in Agents Used for the Treatment of Diastolic and Systolic Heart Failure

SimilaritiesDifferences
β-Blockers• Used to treat HTN• Used to modify left ventricular remodeling to prolong survival in SHF
• May be used to rate control patients with atrial fibrillation or flutter• Titrated slowly to specific dose in SHF
• In DHF, used to decrease heart rate and prolong diastole to reduce symptoms
• DHF titrated more rapidly to response than in SHF
Calcium channel blockers• May be used to treat HTN• Generally avoided in treating SHF
• Shown to improve diastolic parameters and exercise tolerance
• Particularly useful in setting of atrial fibrillation
Diuretics• Symptom reduction through volume reduction in acute and chronic settings• Patients with SHF more likely to require higher doses and long-term therapy
• May be used to treat HTN• Patients with DHF more likely to tolerate weaning
• Judicious use in DHF as patients may be preload-dependent
Nitrates• Used to treat patients with ischemic heart disease
• Contribute to volume reduction
ACEIs• May be used to treat HTN• Ample data to support use in SHF although relatively few studies in patients with DHF
• Associated with LV regression and experimental data suggest improved myocardial relaxation
ARBs• May be used to treat hypertension• Few trials in patients with DHF
• Associated with LV regression and experimental data suggest improved myocardial relaxation
Spironolactone• Aldosterone, which promotes fluid retention, myocardial, and vascular fibrosis is blocked. May have benefit in both DHF and SHF treatment• Shown to improve symptoms, decrease risk of death, and hospitalization in SHF
Digoxin*• Beneficial for rate control in patients with atrial fibrillation or flutter• Used to improve ejection fraction in patients with SHF
• May increase intracellular calcium concentration, which may impair diastolic relaxation
  • * Digoxin use is controversial in the treatment of DHF.

  • β-blocker, β-adrenergic receptor blocker; ACEI, angiotensin-converting enzyme inhibitor; ARB, angiotensin receptor blocker; HTN, hypertension; SHF, systolic heart failure; DHF, diastolic heart failure; LV, left ventricle.
