Background:
- Adenosine is an endogenous nucleoside with established cardiovascular applications.
- Its use extends to diagnostic procedures and therapeutic interventions.
Purpose of the Study:
- To review the multifaceted roles of adenosine in cardiovascular medicine.
- To highlight its utility in pharmacologic stress testing and interventional cardiology.
Main Methods:
- Review of existing literature on adenosine's cardiovascular uses.
- Analysis of its application in stress tests, cardiac catheterization, and acute myocardial infarction treatment.
Main Results:
- Adenosine is effective for pharmacologic stress tests.
- Direct coronary artery administration aids in fractional flow reserve measurement and treating no-reflow.
- Adenosine improves outcomes when used with thrombolytics for myocardial infarction.
Conclusions:
- Adenosine is a valuable agent for cardiovascular evaluation and treatment.
- Its diverse applications underscore its importance in managing cardiac conditions.
Abstract:
Adenosine is an endogenous nucleoside available for the diagnosis and treatment of various cardiovascular conditions. It may be given for pharmacologic stress tests as well as administered directly into the coronary arteries during cardiac catheterization. The latter treatment may be utilized to measure fractional flow reserve in addition to treating the no-reflow phenomenon. Adenosine has also been shown to improve the clinical outcome of thrombolytics given in the setting of acute myocardial infarction. Adenosine is a useful agent for evaluation and treatment of the cardiovascular system.

Antianginal Drugs: Nitrates and β-Blockers
Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow. Administered...
