Quick-acting heart pills are known to relieve tension, and patients with angina often take them orally during an angina attack. Angina is due to the presence of severe stenosis or even occlusion of the coronary arteries in patients with coronary heart disease. When the oxygen consumption of the heart muscle increases, the oxygen supply cannot keep up in time, and an imbalance between oxygen demand and supply occurs, triggering the symptoms of angina. The herbal ingredients of the quick-acting heart pill contain Chuanxiong and ice chips, and ice chips can not only play a role in relieving pain, but also can make the body appear sedated, which can relieve the body’s nervous discomfort. When the body’s tension is relieved, it can reduce the oxygen consumption of the heart muscle. Not only that, but ice chips can also effectively make the coronary artery blood vessels dilate, effectively improving the blood supply to the heart muscle. Therefore, quick-acting heart pills can relieve tension, and tension can reduce myocardial oxygen consumption, which is also one of the mechanisms of quick-acting heart pills to relieve angina.
