Abstract

Intravenous positive inotropic agents play an important role in the short-term management of acute decompensated heart failure. The most commonly used positive inotropic agents are beta-adrenergic agonists and phosphodiesterase inhibitors. Positive inotropic effect of these drugs is primarily through increasing cAMP and calcium concentration in cardiac myocytes, in which circumstance increased intracellular calcium consentrations may lead to serious adverse events. Calcium-sensitizing agents, in contrast, exert positive inotropic action by increasing the sensitivity of the contractile apparatus to calcium. Theoretically, these agents do not present major limitations of cAMP-dependent agents because they increase myocardial contractility without increasing intracellular cAMP or calcium. Levosimendan is a new calcium-sensitizing agent used in the treatment of decompensated heart failure. In this paper, we reviewed the use of intravenous positive inotropic agents and levosimendan in the treatment of acute decompensated heart failure.

Özet

Akut dekompanse kalp yetersizliği tedavisinde intravenöz pozitif inotropik ajanlar oldukça önemli bir rol oynamaktadır. En sık kullanılan inotropik ajanlar beta-adrenerjik agonistler ve fosfodiesteraz inhibitörleridir. Bu ilaçlar pozitif inotropik etkilerini kas hücresinde kalsiyum ve siklik AMP (cAMP) konsantrasyonunu artırarak gösterdiklerinden, hücre içi kalsiyum konsantrasyonunun artması istenmeyen ciddi olaylara neden olmaktadır. Kalsiyum duyarlılaştırıcı ajanlar kasılma elemanlarının kalsiyuma duyarlılığını artırarak pozitif inotropik etki gösterir. Teorik olarak bu ilaçlar hücre içi cAMP ve kalsiyum konsantrasyonunu artırmadan miyokard kontraktilitesini artırdıkları için, cAMP bağımlı ajanların olumsuz özelliklerini göstermez. Levosimendan dekompanse kalp yetersizliği tedavisinde kullanılan, kalsiyum duyarlılaştırıcı yeni bir inotropik ajandır. Bu derlemede, kalp yetersizliğinin akut alevlenmesinin tedavisinde kullanılan intravenöz pozitif inotropik ajanlar ve yeni bir inotropik ajan olan levosimendanın gözden geçirilmesi amaçlandı.
