Summary Introduction

The heart is the unique organ that pumps oxygenated blood and receives deoxygenated blood from other organs. Various malfunctions damage the heart such as low oxygen level causes angina pectoris, damage of heart cells leads to ischemia later to ischemic heart disease, deposits of fatty materials in the artery leads to Coronary Heart Disease (CAD), and acute CAD leads to heart attack. The angina pectoris is classified into three classical types of chest pain, namely chronic stable angina, unstable angina, and vasospastic angina. The nitrates and nitrites, calcium channel blockers (CCBs), and the beta-blockers are the classical three classes of drug that are used as antianginal drugs.
