Abstract

The heart is a bio pump responsible for the provision of oxygen and nutrients to all body cells and it plays a vital role in the survival of the organism. The essential function of the heart is performed through the close interaction of cardiac myocytes with endocardial and capillary endothelial cells. The endothelium releases nitric oxide (NO) and modulates several physiological and pathological processes. The cardiac myocyte is also capable of NO production. Although the effect of NO on cardiac responses has been examined, data regarding the effect of NO on the heart remain controversial. The discrepancies in studies can be explained by several factors, such as different animal species, preparation, redox status and NO concentration. However, increasing interest in the role of NO has generated significant progress in the investigation of NO-based therapies. In this review, first, the general properties of NO are described as well as the physiological functions and pathological role in the heart. Then an evaluation is made of several important NO-related treatment options such as NO donors, NO synthase inhibitors, phosphodiesterase inhibitors and sGC stimulators/activators. A summary is also given of NO-based drug candidates planned for use in clinical trials in the near future.
